Installation Instructions3.1 GeneralThese installation steps are designed to lead you through the proper installation and setup of a SERVOSTAR CD SynqNetsystem. They were developed with the assumption that you have a fundamental understanding of basic electronics, computers, mechanics, and proper safety practices. However, you do not have to be an expert in motion control to install and operate thedrive system. It is recommended that you read the entire manual completely before attempting installation or operation.High voltage can present dangerous and hazardous conditions if not performed by a qualified electrician. Be certain to follow all national and local codes during installation.1. Open the box(es) and remove all the contents. Check to ensure there is no visible damage to any of the equipment.2. Mount the SERVOSTAR CD SynqNet to the back panel. Refer to the appropriate Outline Dimensions in this manual. Metal-to-metal contact is important for electrical noise control!3. Wire the SERVOSTAR CD SYNQNET according to the appropriate System Wiring Diagram.4. Connect solid earth ground to frames of all components.5. Wire the main power (115/230 VAC). Wire the 24 volt supply to the connector at the top of the drive.6. Wire user I/O at connector C3: At a minimum, 24 volts must be brought in to the enable circuit. Be certain that connector C3 is inserted correctly.7. Wire the motor and feedback. Refer to the Feedback Wiring Diagram for additional information. 8. Wire Regen Resistor kit, if applicable. 9.Verify that all wiring is correct.10. Verify that earth grounds are connected. 11. Verify all electrical and safety codes are met.12. Connect the SynqNet cable between the Motion Controller and connector C4.3.2 GroundingSystem grounding is essential for proper performance of the drive system. A ground bus bar may be used as a single point ground for the system. Safety grounding should be provided to all pieces of the system from a “star point." In addition to the safety grounding, a high frequency ground must be provided that connects the back panel to the enclosure and, ultimately, to earth ground. The objective is to provide an extremely low impedance path between the filters, drives, power supplies, and earth ground. This high frequency ground is accomplished with the use of a flat braid or copper bus bar. It is important not to rely on a standard wire for the high frequency ground. In general, a wire has an inductance of 8nH-per-inch, regardless of diameter. At higher frequencies, this unwanted inductance between grounds equates to limited filter performance. When connecting high frequency grounds, use the shortest braid possible.3.3 BondingThe proper bonding of shielded cables is imperative for minimizing noise emissions and increasing immunity levels of the drive system. Its effect is to reduce the impedance between the cable shield and the back panel. Kollmorgen recommends that all shielded cables be bonded to the back panel.Power input wiring does not require shielding (screening) if the power is fed to the cabinet (enclosure) via metallized conduit. If metallized conduit is not implemented into the system, shielded cable is required on the power input wires and proper bonding technologies should be implemented.The motor and feedback cables should have the shield exposed as close to the drive as possible. This exposed shield is bonded to the back panel using either non-insulated metallic cable clamps or cable bonding clamps offered by Phoenix Contact (and others).3.4 CEFilteringThe SERVOSTAR drive system (drive, motor) has been designed to meet the CE standards. It is imperative for you to apply proper bonding and grounding techniques, described earlier in this section, when incorporating EMC noise filtering components for the purpose of meeting this standard.Noise currents often occur in two types. The first is conducted emissions that are passed through ground loops. The quality of the system grounding scheme inversely determines the noise amplitudes in the lines. These conducted emissions are of a common-mode nature from line to neutral (or ground). The second is radiated high-frequency emissions usually capacitively coupled from line-to-line and are differential in nature.To properly mount the filters, the enclosure should have an unpainted metallic surface. This allows for more surface area to be in contact with the filter housing and provides a lower impedance path between this housing and the back plane. The back panel, in turn, has a high frequency ground strap connection to the enclosure frame or earth ground.3.4.1 InputPowerThe Kollmorgen SERVOSTAR CD SynqNet electronic system components require EMI filtering in the input power leads to meet the conducted emission requirements for the industrial environment. This filtering blocks conducted-type emissions from exiting onto the power lines and provides a barrier for EMI on the power lines.Care must be taken to adequately size the system. The type of filter is based on the voltage and current rating of the system and whether the incoming line is single or three-phase. One input line filter is used for multi-axis control applications. These filters are mounted as close to the incoming power as possible so noise is not capacitively coupled into other signal leads and cables. Similarly, care should be taken when routing wires from the load side of the filter to the BUS Module. These lines may be noisy and should be separated from other sensitive cabling to avoid unwanted coupling of noise. Several manufacturers of these filters are listed below. They should be able to recommend the best filter design for most typical motor control applications. Kollmorgen has also provided specific filters recommendations that adequately attenuate the conducted noise to levels well below the CE limits. The implementation of the EMI filter should be done in accordance with the following guidelines: • Filter should be mounted on the same panel as the drive.• Filter should be mounted as close as possible to incoming cabinet power.• When mounting the filter to the panel, remove any paint or material covering. Use an unpainted metallic back panel, if possible.• Filters are provided with an earth connection. All ground connections are tied to ground.• Filters can produce high leakage currents. Filters must be earthed before connecting the supply!• Filters should not be touched for a period of 10 seconds after removing the supply.The following table shows recommended line filters:Drive Model # Recommended EMI Line FilterKollmorgen Part #Lx03 Filter Concepts SF7Schaffner FN258-7/07 n/aA-96776-001Lx06 Filter Concepts SF15Schaffner FN258-16/07 N/aA-96776-002Lx10 SchaffnerFN258-16/07A-96776-002 Lx20The filters called out in the table on the previous page are used on a one-to-one corresponedence withthe drive. If drives are paralled off one filter, it needs to be sized.Drives can be ganged off one EMI filter as shown in the Filter and Bonding Diagrams.3.4.2 Motor Line FilteringMotor filtering may not be necessary for CE compliance of SERVOSTAR systems. However, this additional filtering increasesthe reliability of the system. Poor non-metallic enclosure surfaces and lengthy, unbonded (or unshielded) motor cables thatcouple noise line-to-line (differential) are just some of the factors that lead to the necessity of motor lead filtering.Motor lead noise may be either common-mode or differential. The common-mode conducted currents occur between eachmotor lead and ground (line-to-neutral). Differential radiated currents exist from one motor lead to another (line-to-line). Thefiltering of the lines feeding the motor provide additional attenuation of noise currents that enter surrounding cables andequipment I/O ports in close proximity.Differential mode currents commonly occur with lengthy motor cables. As the cable length increases, so does its capacitanceand its ability to couple noise from line-to-line. While every final system is different and every application of the product causesa slightly different emission profile, it may become necessary to use differential mode chokes to provide additional noiseattenuation to minimize the radiated emissions. The use of a ferrite core (placed at the drive end) on each motor lead (shown inthe diagram below), attenuates differential mode noise and lower frequency (30-60 MHz) broadband emissions to withinspecifications. Kollmorgen recommends a Fair-Rite P/N 2643665702 (or equivalent) ferrite core. You should wrap each motorlead through the core several times, as shown in the next figure.Never wrap a ground lead through a core.To MotorCommon ModeFilteringDifferential Mode FilteringCommon mode currents occur from noise spikes created by the PWM switching frequency of the drive. The use of a ferrite or iron-powder core toroid, as shown in the figure above, places common mode impedance in the line between the motor and the drive. The use of a common mode choke on the motor leads may increase signal integrity of encoder outputs and associated I/O signals. The following is a list of toroidal and ferrite cores used to make common mode chokes:3.4.3 I/O FilteringI/O filtering, while not a necessity for CE compliance, may be desired (depending on system installation, application, andintegration with other equipment). It may be necessary to place ferrite cores on I/O lines to avoid unwanted signals entering and disturbing the drive system or other associated equipment. The following chart lists some ferrite parts that may be used for I/O filtering and noise attenuation. These parts are ideal for providing an in-line common mode impedance for I/O linesThe following figure illustrates the use of multiple turns through a clamp-on core. The more turns created, the more impedance is added to the line. Avoid putting the shield in a clamp-on core. It is undesirable to place an impedance inline with the shield. The use of ribbon cable may be common in many cabinets. Some ferrite clamps are designed just for ribbon cable use.4.

The use of armored (screened) motorcables bonded as close to the drive as possible are essential for CE compliance and stronglyrecommended to better the overall performance and reliability of the system.Note 6for CE compliance. As with the motor cables, the feedback cables should be bonded to the back panel. This bonding does twothings. First, it cuts down radiation from the drive, which may be in the form of high frequency energy resulting from internal processor clocks. Second, it providesimmunity for the drive. Since the feedback device is located internal to the motor, it is going to pick up some noise currents and transmit bonding directs the currents from the shield of the feedback cable to back panel ground. This reduces the amount of noise entering the drive.Note 7AC power lines that must be routed past other lines (such as motor cables or I/O lines) should cross at a 90º angle. This minimizes the coupling effect. Additionally, the power lines should be routed as close to the back panel aspossible. Any noise currents on the lines are capacitively coupled to the ground plane and not to other lines.Note 8Control (I/O) signals should be kept separate from all power and motor cables, if possible. Keep control wiring as short as possible and use screened wire. Bonding is also recommended but not required for CE compliance. A separation distance of 20 cm. (8 in.) is sufficient in most cases. Where control cables must cross power cables, they should cross at a 90ºangle.Note 9Motor cables and feedback cables exiting the cabinet going to the motor should be separated as much as possible. Ideally, the use of separate conduits provides good isolation, which can limit coupling of noise from motor to feedback cables.Note 1Input power enters enclosure from metal conduit. Thiseliminates the need for shielded input power cable.Note 2Single point ground. A bus bar (ground bus) is an excellent way to achieve this.Note 3High frequency ground between non-conductive back panel and enclosure. Also, a high frequency ground is required between the enclosure and earth ground.Note 4EMI filter grounding. Safetygrounds must be provided on the filters. Hazard potentials exist even when the power is off because of the capacitors internal to the filters.。

These systems allow users to issue commandsto the operating system by pointing to these icons by means of a mouse and pressing a button on the mouse. Older shells communicate with users through textualmessages using a keyboard and monitor screen.为了执行计算机的用户要求的操作,操作系统必须能够与用户进行通信。
部分操作系统处理这种通信通常被称为壳。
现代的外壳执行此任务通过一个图形用户界面(GUI)中,被操纵的对象,如文件和程序,代表pictoriallyon显示屏上的图标。
如何在C#用WM_COPYDATA消息来实现两个进程之间传递数据
如何在C#⽤WM_COPYDATA消息来实现两个进程之间传递数据简介:本⽂着重讲述了如果⽤WM_COPYDATA消息来实现两个进程之间传递数据.进程之间通讯的⼏种⽅法:在Windows程序中,各个进程之间常常需要交换数据,进⾏数据通讯。
常⽤的⽅法有使⽤内存映射⽂件通过共享内存DLL共享内存使⽤SendMessage向另⼀进程发送WM_COPYDATA消息⽐起前两种的复杂实现来,WM_COPYDATA消息⽆疑是⼀种经济实惠的⼀中⽅法.WM_COPYDATA消息的主要⽬的是允许在进程间传递只读数据。
Windows在通过WM_COPYDATA消息传递期间,不提供继承同步⽅式。
SDK⽂档推荐⽤户使⽤SendMessage函数,接受⽅在数据拷贝完成前不返回,这样发送⽅就不可能删除和修改数据:这个函数的原型及其要⽤到的结构如下:SendMessage(hwnd,WM_COPYDATA,wParam,lParam);其中,WM_COPYDATA对应的⼗六进制数为0x004AwParam设置为包含数据的窗⼝的句柄。
lParam指向⼀个COPYDATASTRUCT的结构:typedef struct tagCOPYDATASTRUCT{DWORD dwData;//⽤户定义数据DWORD cbData;//数据⼤⼩PVOID lpData;//指向数据的指针}COPYDATASTRUCT;该结构⽤来定义⽤户数据。
具体过程如下:⾸先,在发送⽅,⽤FindWindow找到接受⽅的句柄,然后向接受⽅发送WM_COPYDATA消息.接受⽅在DefWndProc事件中,来处理这条消息.由于中⽂编码是两个字节,所以传递中⽂时候字节长度要搞清楚.代码中有适量的解释,⼤家请⾃⼰看吧.具体代码如下://---------------------------------------------------//发送⽅://---------------------------------------------------using System;using System.Drawing;using System.Collections;using ponentModel;using System.Windows.Forms;using System.Data;using System.Runtime.InteropServices;namespace WindowsFormGetMsg{public class Form1 : System.Windows.Forms.Form{private System.Windows.Forms.TextBox textBox1;private ponentModel.Container components = null;const int WM_COPYDATA = 0x004A;public Form1(){InitializeComponent();}protected override void Dispose( bool disposing ){if( disposing ){if (components != null){components.Dispose();}}base.Dispose( disposing );}#region Windows Form Designer generated codeprivate void InitializeComponent(){this.textBox1 = new System.Windows.Forms.TextBox();this.SuspendLayout();//// textBox1//this.textBox1.Location = new System.Drawing.Point (176, 32); = "textBox1";this.textBox1.Size = new System.Drawing.Size(160, 21);this.textBox1.TabIndex = 0;this.textBox1.Text = "textBox1";//// Form1//this.AutoScaleBaseSize = new System.Drawing.Size(6, 14);this.ClientSize = new System.Drawing.Size(432, 266);this.Controls.AddRange(newSystem.Windows.Forms.Control[] {this.textBox1}); = "Form1";this.Text = "接收⽅";this.ResumeLayout(false);}#endregion[STAThread]static void Main(){Application.Run(new Form1());}protected override void DefWndProc(refSystem.Windows.Forms.Message m){switch(m.Msg){//接收⾃定义消息 USER,并显⽰其参数case WM_COPYDATA:COPYDATASTRUCT mystr = new COPYDATASTRUCT(); Type mytype = mystr.GetType(); mystr =(COPYDATASTRUCT)m.GetLParam(mytype); this.textBox1.Text =mystr.lpData;break;default:base.DefWndProc(ref m);break;}}}[StructLayout(LayoutKind.Sequential)]public struct COPYDATASTRUCT{public IntPtr dwData;public int cbData;[MarshalAs(UnmanagedType.LPStr)] public string lpData; }}//---------------------------------------------------//接受⽅//---------------------------------------------------using System;using System.Drawing;using System.Collections;using ponentModel;using System.Windows.Forms;using System.Data;using System.Runtime.InteropServices;namespace WindowsFormGetMsg{public class Form1 : System.Windows.Forms.Form{private System.Windows.Forms.TextBox textBox1;private ponentModel.Container components = null; const int WM_COPYDATA = 0x004A;public Form1(){InitializeComponent();}protected override void Dispose( bool disposing ){if( disposing ){if (components != null){components.Dispose();}}base.Dispose( disposing );}#region Windows Form Designer generated codeprivate void InitializeComponent(){this.textBox1 = new System.Windows.Forms.TextBox();this.SuspendLayout();//// textBox1//this.textBox1.Location = new System.Drawing.Point(176, 32); = "textBox1";this.textBox1.Size = new System.Drawing.Size(160,21);this.textBox1.TabIndex = 0;this.textBox1.Text = "textBox1";//// Form1//this.AutoScaleBaseSize = new System.Drawing.Size(6, 14);this.ClientSize = new System.Drawing.Size(432, 266);this.Controls.AddRange(newSystem.Windows.Forms.Control[] {this.textBox1}); = "Form1";this.Text = "接收⽅";this.ResumeLayout(false);}#endregion[STAThread]static void Main(){Application.Run(new Form1());}protected override void DefWndProc(refSystem.Windows.Forms.Message m){switch(m.Msg){//接收⾃定义消息 USER,并显⽰其参数case WM_COPYDATA:COPYDATASTRUCT mystr = new COPYDATASTRUCT(); Type mytype = mystr.GetType(); mystr =(COPYDATASTRUCT)m.GetLParam(mytype); this.textBox1.Text =mystr.lpData;break;default:base.DefWndProc(ref m);break;}}}[StructLayout(LayoutKind.Sequential)]public struct COPYDATASTRUCT{public IntPtr dwData;public int cbData;[MarshalAs(UnmanagedType.LPStr)] public string lpData; }}。

Introduction to the operating system of the new technology Abstract:the Operating System (Operating System, referred to as OS) is an important part of a computer System is an important part of the System software, it is responsible for managing the hardware and software resources of the computer System and the working process of the entire computer coordination between System components, systems and between users and the relationship between the user and the user. With the appearance of new technology of the operating system functions on the rise. Operating system as a standard suite must satisfy the needs of users as much as possible, so the system is expanding, function of increasing, and gradually formed from the development tools to system tools and applications of a platform environment. To meet the needs of users. In this paper, in view of the operating system in the core position in the development of computer and technological change has made an analysis of the function of computer operating system, development and classification of simple analysis and elaborationKey words: computer operating system, development,new technology Operating system is to manage all the computer system hardware resources include software and data resources; Control program is running; Improve the man-machine interface; Provide support for other application software, etc., all the computer system resourcesto maximize the role, to provide users with convenient, efficient, friendly service interface.The operating system is a management computer hardware and software resources program, is also the kernel of the computer system and the cornerstone. Operating system have such as management and configuration memory, decided to system resources supply and demand of priorities, control input and output devices, file system and other basic network operation and management affairs. Operating system is to manage all the computer system hardware resources include software and data resources; Control program is running; Improve the man-machine interface; Provide support for other application software, etc., all the computer system resources to maximize the role, to provide users with convenient, efficient, friendly service interface. Operating system is a huge management control procedures, including roughly five aspects of management functions, processes and processor management, operation management, storage management, equipment management, file management. At present the common operating system on microcomputer DOS, OS / 2, UNIX, XENIX, LINUX, Windows, Netware, etc. But all of the operating system with concurrency, sharing, four basic characteristics of virtual property and uncertainty. At present there are many different kinds of operating system, it is difficultto use a single standard unified classification. Divided according to the application field, can be divided into the desktop operating system, server operating system, the host operating system, embedded operating system.1.The basic introduction of the operating system(1)The features of the operating systemManagement of computer system hardware, software, data and other resources, as far as possible to reduce the work of the artificial allocation of resources and people to the machine's intervention, the computer automatically work efficiency into full play.Coordinate the relationship between and in the process of using various resources, make the computer's resources use reasonable scheduling, both low and high speed devices running with each other.To provide users with use of a computer system environment, easy to use parts of a computer system or function. Operating system, through its own procedures to by all the resources of the computer system provides the function of the abstract, the function of the formation and the equivalent of the operating system, and image, provide users with convenient to use the computer.(2)The development of the operating systemOperating system originally intended to provide a simple sorting ability to work, after updating for auxiliary more complex hardwarefacilities and gradual evolution.Starting from the first batch mode, also come time sharing mechanism, in the era of multiprocessor comes, the operating system also will add a multiprocessor coordination function, even the coordination function of distributed systems. The evolution of the other aspects also like this.On the other hand, on a personal computer, personal computer operating system of the road, following the growth of the big computer is becoming more and more complex in hardware, powerful, and practice in the past only large computer functions that it step by step.Manual operation stage. At this stage of the computer, the main components is tube, speed slow, no software, no operating system. User directly using a machine language program, hands-on completely manual operation, the first will be prepared machine program tape into the input, and then start the machine input the program and data into a computer, and then through the switch to start the program running and computing, after the completion of the printer output. The user must be very professional and technical personnel to achieve control of the computer.Batch processing stage. Due to the mid - 1950 - s, the main components replaced by the transistor computer, running speed hadthe very big enhancement, the software also began to develop rapidly, appeared in the early of the operating system, it is the early users to submit the application software for management and monitoring program of the batch.Multiprogramming system phase. As the medium and small-scale integrated circuit widely application in computer systems, the CPU speed is greatly increased, in order to improve the utilization rate of CPU and multiprogramming technology is introduced, and the special support multiprogramming hardware organization, during this period, in order to further improve the efficiency of CPU utilization, a multichannel batch system, time-sharing system, etc., to produce more powerful regulatory process, and quickly developed into an important branch of computer science, is the operating system. Collectively known as the traditional operating system.Modern operating systems. Large-scale, the rapid development of vlsi rapidly, a microprocessor, optimization of computer architecture, computer speed further improved, and the volume is greatly reduced, for personal computers and portable computer appeared and spread. Its the biggest advantage is clear structure, comprehensive functions, and can meet the needs of the many USES and operation aspects.2. New technology of the operating systemFrom the standpoint of the operating system of the new technology, it mainly includes the operating system structure design of the micro kernel technology and operating system software design of the object-oriented technology.(1) The microkernel operating system technologyA prominent thought in the design of modern operating systems is the operating system of the composition and function of more on a higher level to run (i.e., user mode), and leave a small kernel as far as possible, use it to complete the core of the operating system is the most basic function, according to the technology for micro kernel (Microkernel) technology.The microkernel structure(1) Those most basic, the most essential function of the operatingsystem reserved in the kernel(2)Move most of the functionality of the operating system intothe kernel, and each operating system functions exist in theform of a separate server process, and provide services.(3)In user space outside of the kernel including all operatingsystem, service process also includes the user's applicationprocess. Between these processes is the client/server mode.Micro kernel contains the main ingredient(1) Interrupt and the exception handling mechanism(2)Interprocess communication mechanisms(3)The processor scheduling mechanism(4)The basic mechanism of the service functionThe realization of the microkernelMicro kernel implementation "micro" is a major problem and performance requirements of comprehensive consideration. To do "micro" is the key to implementation mechanism and strategy, the concept of separation. Due to the micro kernel is the most important of news communication between processes and the interrupt processing mechanism, the following briefly describes the realization of both.Interprocess communication mechanismsCommunication service for the client and the server is one of the main functions of the micro kernel, is also the foundation of the kernel implement other services. Whether to send the request and the server reply messages are going through the kernel. Process of news communication is generally through the port (port). A process can have one or more ports, each port is actually a message queue or message buffer, they all have a unique port ID (port) and port authority table, the table is pointed out that this process can be interactive communications and which process. Ports ID and kernel power table maintenance.Interrupt processing mechanismMicro-kernel structure separation mechanism will interrupt and the interrupt processing, namely the interrupt mechanism on micro kernel, and put the interrupt handling in user space corresponding service process. Micro kernel interruption mechanism, is mainly responsible for the following work:(1) When an interrupt occurs to identify interrupt;(2) Put the interrupt signal interrupt data structure mapping tothe relevant process;(3) The interrupt is transformed into a message;(4) Send a message to the user space in the process of port, butthe kernel has nothing to do with any interrupt handling.(5) Interrupt handling is to use threads in a system.The advantages of the microkernel structure(1) Safe and reliableThe microkernel to reduce the complexity of the kernel, reduce the probability of failure, and increases the security of the system.(2) The consistency of the interfaceWhen required by the user process services, all based on message communication mode through the kernel to the server process. Therefore, process faces is a unified consistent processescommunication interface.(3) Scalability of the systemSystem scalability is strong, with the emergence of new hardware and software technology, only a few change to the kernel.(4) FlexibilityOperating system has a good modular structure, can independently modify module and can also be free to add and delete function, so the operating system can be tailored according to user's need.(5) CompatibilityMany systems all hope to be able to run on a variety of different processor platform, the micro kernel structure is relatively easy to implement.(6) Provides support for distributed systemsOperating under the microkernel structure system must adopt client/server mode. This model is suitable for distributed systems, can provide support for distributed systems.The main drawback of microkernelUnder the micro-kernel structure, a system service process need more patterns (between user mode and kernel mode conversion) and process address space of the switch, this increases costs, affected the speed of execution.3 .Object-oriented operating system technologyObject-oriented operating system refers to the operating system based on object model. At present, there have been many operating system used the object-oriented technology, such as Windows NT, etc. Object-oriented has become a new generation of an important symbol of the operating system.The core of object-oriented conceptsIs the basic idea of object-oriented to construct the system as a series of collections of objects. The object refers to a set of data and the data of some basic operation encapsulated together formed by an entity. The core of object-oriented concept includes the following aspects:(1) EncapsulationIn object-oriented encapsulation is the meaning of a data set and the data about the operation of the packaging together, form a dynamic entity, namely object. Encapsulated within the request object code and data to be protected.(2) InheritanceInheritance refers to some object can be inherited some features and characteristics of the object.(3) PolymorphismPolymorphism refers to a name a variety of semantics, or the same interface multiple implementations. Polymorphism inobject-oriented languages is implemented by overloading and virtual functions.(4) The messageNews is the way of mutual requests and mutual cooperation between objects. An object through the message to activate another object. The message typically contains a request object identification and information necessary to complete the work.Object-oriented operating systemIn object-oriented operating system, the object as a concurrent units, all system resources, including documents, process and memory blocks are considered to be an object, such as the operating system resources are all accomplished through the use of object services.The advantages of object-oriented operating system:(1)Can reduce operating system throughout its life period whena change is done to the influence of the system itself.For example, if the hardware has changed, will force the operating system also changes, in this case, as long as change the object representing the hardware resources and the operation of the object of service, and those who use only do not need to change the object code.(2)Operating system access to its resources and manipulation are consistent .Operating system to produce an event object, delete, and reference, and it produces reference, delete, and a process object using the same method, which is implemented by using a handle to the object. Handle to the object, refers to the process to a particular object table in the table.(3)Security measures to simplify the operating system.Because all the objects are the same way, so when someone tries to access an object, security operating system will step in and approved, regardless of what the object is.(4)Sharing resources between object for the process provides a convenient and consistent approach.Object handle is used to handle all types of objects. The operating system can by tracking an object, how many handle is opened to determine whether the object is still in use. When it is no longer used, the operating system can delete the object.ConclusionIn the past few decades of revolutionary changes have taken place in the operating system: technological innovation, the expansionof the user experience on the upgrade, application field and the improvement of function. As in the past few decades, over the next 20 years there will be huge changes in operating system. See we now use the operating system is very perfect. Believe that after the technology of the operating system will still continue to improve, will let you use the more convenient. Believe that the operating system in the future will make our life and work more colorful.。

软件系统之间的接口方式
软件系统之间的接口方式•概述软件接口是实现一个系统跟另外系统进行信息交互的桥梁,在不同的系统之间,根据系统的关联程度的不同存在紧耦合和松耦合两种:紧耦合要求接口响应反应快,消息不能阻塞;松耦合对响应反应要求比较低。
在目前应用中, Socket 、消息队列(Message Queue)、 WebService等都有相应的应用,但是应用中发现各通讯方式有自己固有的特征,“适合的才是最好的”,这是真理。
在接口和系统信息交互的过程中,两种模式使用得很普遍:同步调用和异步调用,同步调用要求接口发出请求消息后必须等待服务端系统的应答消息,接口阻塞直至超时;异步调用则发出请求消息后,接口可以从事其它处理,定时轮询服务端应答消息和消息或事件通知。
同步方式简单,但是很容易造成接口阻塞,造成消息积压超时。
•技术实现• Socket 通讯Socket 通讯相对来说是很古老的通讯方式,也是最常用的通讯方式。
Socket 通讯有阻塞和非阻塞两种方式。
在同步方式,采用阻塞编程比较简单,但是为了防止接口阻塞,我们需要设置 Socket 超时,因此可以使用 Socket 的 SELECT 模型(参考如下示例代码):ReceLen=0;CurReceLen=0;for(;;){iResult=select(0,&fdread,NULL,NULL,&timeout);if(iResult==0){AfxMessageBox("接收应答消息超时!!!",MB_OK|MB_ICONERROR); closesocket(Socket);return FALSE;}CurReceLen = recv(Socket, oBuf+ReceLen, len, NO_FLAG_SET); if((CurReceLen>0) && (CurReceLen != SOCKET_ERROR)){oBuf[ReceLen+CurReceLen]='\0';memcpy((char *)&MsgLen,oBuf,sizeof(WORD32));MsgLen=ntohl(MsgLen);if(ReceLen+CurReceLen==MsgLen){ReceLen+=CurReceLen;break;}ReceLen+=CurReceLen;}}在异步方式下,采用非阻塞方式实现比较方便,在非阻塞方式下可使用WSAAsyncSelect模型和 WSAEventSelect 模型: WSAAsyncSelect模型基于消息,WSAEventSelect 模型基于事件,下面的示例代码设置了 Socket 进行读写和关闭操作的消息:status = WSAAsyncSelect(TempSocket, hWnd, WSA_READ, FD_READ | FD_CLOSE | FD_WRITE);if (status == SOCKET_ERROR){WriteLogFile("Set stream socket module fail!!!IP(%s),Port(%d) and error(%d)",GetIPAddr((PeerMap+node)->IPAddr),(PeerMap+node)->PeerPortNo,WS AGetLastError());CloseSocket(TempSocket,__LINE__,__FILE__);return FALSE;}无论使用阻塞方式或非阻塞方式编程,需要重点考虑的一个问题:粘包现象,即应用发送两个或以上的数据包,在 Socket 通讯层将数据包合并成一个发送出去,因此接收端收到数据包以后需要对数据包根据应用定义的长度进行拆分,否则导致应用层丢包。

托盘程序
静态托盘程序的编写过程往NotifyIcon实例中添加菜单,首先要创建ContextMenu实例,此实例主要作用是表示快捷菜单,其中的菜单项是通过创建MenuItem实例来实现,托盘程序中的菜单有几个菜单项,就创建几个MenuItem实例。
然后把这些菜单项加入到ContextMenu实例,并把此实例赋值给NotifyIcon实例的ContextMenu属性,这样托盘程序右键点击弹出的菜单就完成了。
下面是具体代码:创建ContextMenu实例和MenuItem实例:FriendWithEventsContextMenu1 As System.Windows.Forms.ContextMenu FriendWithEventsMenuItem1 As System.Windows.Forms.MenuItem FriendWithEventsMenuItem2 As System.Windows.Forms.MenuItem FriendWithEventsMenuItem3 As System.Windows.Forms.MenuItem把这些菜单项加入到ContextMenu实例,并把ContextMenu实例赋值给NotifyIcon实例的ContextMenu属性:Me.MenuItem1=NewSystem.Windows.Forms.MenuItem()Me.MenuItem2=NewSystem.Windows.Forms.MenuItem()Me.MenuItem3=NewSystem.Windows.Forms.MenuItem()Me.NotifyIcon1.ContextMenu=Me.ContextMenu1Me.NotifyIcon1.Text="的托盘程序"Me.NotifyIcon1.Visible=True'设定托盘程序托盘区位置显示图标Me.NotifyIcon1.Icon=TrayIcon'在ContextMenu实例中加入菜单项Me.ContextMenu1.MenuItems.Add(Me.MenuItem1)Me.ContextMenu1.MenuItems.Add(Me.MenuItem2)Me.ContextMenu1.MenuItems.Add(Me.MenuItem3)Me.MenuItem1.Index=0Me.MenuItem1.Text="显示窗体"Me.MenuItem2.Index=1Me.MenuItem2.Text="隐藏窗体"Me.MenuItem3.Index=2Me.MenuItem3.Text="退出"当把ContextMenu实例赋值给NotifyIcon实例的ContextMenu属性后,托盘程序的缺省状态是当鼠标右击托盘图标,就会弹出对应的菜单。
Design Techniques For Emc Part 1 - Circuit Design, And Choice Of Components
Design Techniques for EMC – Part 1Circuit Design, and Choice of ComponentsBy Eur Ing Keith Armstrong CEng MIEE MIEEEPartner, Cherry Clough Consultants, Associate of EMC-UKThis is the first in a series of six articles on best-practice EMC techniques in electrical/electronic/mechanical hardware design, to be published in this journal over the following year. The series is intended for the designer of electronic products, from building block units such as power supplies, single-board computers, and “industrial components” such as motor drives, through to stand-alone or networked products such computers, audio/video/TV, instruments, etc.These articles were first published in the EMC Journal as a series during 1999. This version includes a number of corrections, modifications, and additions, many of which have been made as a result of correspondence with the following, to whom I am very grateful: Feng Chen, Kevin Ellis, Neil Helsby, Mike Langrish, Tom Liszka, Alan Keenan, T Sato, and John Woodgate. I am also indebted to Tom Sato for translating these articles into Japanese and posting them on his website: http://member.nifty.ne.jp/tsato/, as well as suggesting a number of improvements.The techniques covered in these six articles are:1) Circuit design (digital, analogue, switch-mode, communications), and choosingcomponents2) Cables and connectors3) Filters and transient suppressors4) Shielding5) PCB layout (including transmission lines)6) ESD, electromechanical devices, and power factor correctionA textbook could be written about any one of the above topics (and many have), so this magazine article format can do no more than introduce the various issues and point to the most important of the best-practice techniques.Before starting on the above list of topics it is useful see them in the context of the ideal EMC lifecycle of a new product design and development project.The project EMC lifecycleThe EMC issues in a new project lifecycle are summarised below:• Establishment of the target electromagnetic specifications for the new product, including: The electromagnetic environment it must withstand (including continuous, high-probability, and low-probability disturbance events) and the degradation in performance to be allowedduring disturbance events;Its possible proximity to sensitive apparatus and allowable consequences, hence the emissions specifications;Whether there are any safety issues requiring additional electromagnetic performance specifications. Safety compliance is covered by safety directives, not by EMC Directive;All the EMC standards to be met, regulatory compliance documentation to be created, and how much “due diligence” to apply in each case (consider all markets, any customers’ in-house specifications, etc.).• System design:Employ system-level best-practices (“bottom-up”);flow the “top-level” EMC specifications down into the various system blocks (“top-down”).• System block (electronic) designs:Employ electrical/electronic hardware design best-practices (“bottom-up”) (covered by these six articles);Simulate EMC of designs prior to creating hardware, perform simple EMC tests on early prototypes, more standardised EMC tests on first production issue.• Employ best-practice EMC techniques in software design.• Achieve regulatory compliance for all target markets.• Employ EMC techniques in QA to control:All changes in assembly, including wiring routes and component substitutions;All electrical/electronic/mechanical design modifications and software bug-fixes;All variants.• Sell only into the markets originally designed for;To add new markets go through the initial electromagnetic specification stage again. • Investigate all complaints of interference problemsFeed any resulting improvements to design back into existing designs and new products (a corrective action loop).This may look quite daunting, but it is only what successful professional marketeers and engineers already know to do, so as not to expose their company to excessive commercial and/or legal risks.As electronic technology becomes more advanced, more advanced management and design techniques (such as EMC) are required. There is no escaping the ratcheting effects of new electronic technologies if a company wants to remain profitable and competitive. But new electronics technologies are creating the worlds largest market, expected to exceed US$1 trillion annually in value (that’s $1 million million) within a couple of years and continue to increase at 15% or so per annum after that. Rewards are there for those that can take the pace.The following outlines a number of the most important best-EMC-practices. They deal with “what” and “how” issues, rather than with why they are needed or why they work. A good understanding of the basics of EMC is a great benefit in helping to prevent under or over-engineering, but goes beyond the scope of these articles.Table of contents for Part 11.

Circuit design and choice of components for EMCCorrect choice of active and passive components, and good circuit design techniques used from the beginning of a new design and development project, will help achieve EMC compliance in the most cost-effective way, reducing the cost, size, and weight of the eventual filtering and shielding required. These techniques also improve digital signal integrity and analogue signal-to-noise, and can save at least one iteration of hardware and software. This will help new products achieve their functional specifications, and get to market, earlier. These EMC techniques should be seen as a part of a company’s competitive edge, for maximum commercial benefit.1.1 Digital components and circuit design for EMC1.1.1 Choosing componentsMost digital IC manufacturers have at least one glue-logic range with low emissions, and a few versions of I/O chips with improved immunity to ESD. Some offer VLSI in “EMC friendly” versions (some “EMC” microprocessors have 40 dB lower emissions than regular versions).Most digital circuits are clocked with squarewaves, which have a very high harmonic content, as shown by Figure 1.The faster the clock rate, and the sharper the edges, the higher the frequency and emissions levels of the harmonics.So always choose the slowest clock rate, and the slowest edge rate that will still allow the product to achieve its specification. Never use AC when HC will do. Never use HC when CMOS 4000 will do. Choose integrated circuits with advanced signal integrity and EMC features, such as:• Adjacent, multiple, or centre-pinned power and ground.Adjacent ground and power pins, multiple ground and power pins, and centre-pinned power and ground all help maximise the mutual inductance between power and ground current paths, and minimise their self-inductance, reducing the current loop area of the power supply currents and helping decoupling to work more effectively. This reduces problems for EMC and ground-bounce. • Reduced output voltage swing and controlled slew rates.Reduced output voltage swing and controlled slew rates both reduce the dV/dt and dI/dt of the signals and can reduce emissions by several dB. Although these techniques improve emissions, they could worsen immunity in some situations, so a compromise may be needed• Transmission-line matching I/Os.ICs with outputs capable of matching to transmission-lines are needed when high-speed signals have to be sent down long conductors. E.g. bus drivers are available which will drive a 25Ωshunt-terminated load. These will drive 1 off 25Ω transmission line (e.g. RAMBUS); or will drive 2 off 50Ω lines, 4 off 100Ω lines, or 6 off 150Ω lines (when star-connected).• Balanced signalling.Balanced signalling uses ± (differential) signals and does not use 0V as its signal return. Such ICs are very helpful when driving high-speed signals (e.g. clocks > 66MHz) because they help to preserve signal integrity and also can considerably improve common-mode emissions and immunity.• Low ground bounce.ICs with low ground-bounce will generally be better for EMC too.• Low levels of emissions.Most digital IC manufacturers offer glue-logic ranges with low emissions. For instance ACQ and ACTQ have lower emissions than AC and ACT. Some offer VLSI in “EMC friendly” versions, for example Philips have at least two 80C51 microprocessor models which are up to 40dB quieter than their other 80C51 products.• Non-saturating logic preferred.Non-saturating logic is preferred, because its rise and fall times tend to be smoother (slew-rate controlled) and so contain lower levels of high-order harmonics than saturating logic such as TTL.• High levels of immunity to ESD and other disturbing phenomena.Serial communications devices (e.g. RS232, RS 485) are available with high levels of immunity to ESD and other transients on their pins. If their immunity performance isn’t specified to at least the same standards and levels that you need for your product, additional suppression components will be needed.• Low input capacitance.Low input capacitance devices help to reduce the current peaks which occur whenever a logic state changes, and hence reduce the magnetic field emissions and ground return currents (both prime causes of digital emissions).• Low levels of power supply transient currents.Totem-pole output stages in digital ICs go through a brief period when both devices are on, whenever they switch from one state to the other. During this brief period the supply rail is shorted to 0V, and the power supply current transient can exceed the signal’s output current.Both the transient current (sometimes called the ‘shoot-through’ current) and the voltage noise it causes on the power rails are prime causes of emissions. Relevant parameters may include the transient current’s peak value, its d I/d t (or frequency spectrum) and its total charge, any/all of which can be important for the correct design of the power supply’s decoupling. ICs with specified low levels of power supply transients should be chosen where possible.• Output drive capability no larger than need for the application.The output drive current of an IC (especially a bus driver) should be no larger than is needed.Drivers rated for a higher current have larger output transistors, which can mean considerably larger power supply transients. Their increased drive capability can also mean that the traces they drive can experience faster rise and falltimes than are needed, leading to increased overshoot and ringing problems for signal integrity as well as higher levels of RF emissions.All of the above should have guaranteed minimum or maximum (as appropriate) specifications (or at least typical specifications) in their data sheets.Second-sourced parts (with the same type number and specifications but from different manufacturers) can have significantly different EMC performance – something it is important to control in production to ensure continuing compliance in serial manufacture. If products haven’t been EMC tested with the alternative ICs fitted, it will be best to stick with a single source.Suppliers of high-technology ICs may provide detailed EMC design instructions, as Intel does for its Pentium MMO chips. Get them, and follow them closely. Detailed EMC design advice shows that the manufacturer cares about the real needs of his customers, and may tip the balance when choosing devices.Some FPGAs (and maybe other ICs) now have the ability to program the slew rate, output drive capability and/or output impedance of their drive signals. Their drive characteristics can be adjusted to give better signal integrity and/or EMC performance and this should help save time in development by reducing the need to replace ICs, change the values of components on the PCB, or modify the PCB layout.Where ICs’ EMC performances are unknown, correct selection at an early design stage can be made by EMC testing a variety of contenders in a simple standard functional circuit that at least runs their clocks, preferably performs operations on high-rate data too.Testing for emissions can easily be done in a few minutes on a standard test bench with a close-field magnetic loop probe connected to a spectrum analyser (or a wideband oscilloscope). Some devices will be obviously much quieter than others. Testing for immunity can use the same probe connected to the output of a signal generator (continuous RF or transient) – but if it is a proprietary probe (and not just a shorted turn of wire) first check that its power handling is adequate.Close-field probes need to be held almost touching the devices or PCBs being probed. To locate the “hottest spots” and maximise probe orientation they should first be scanned in a horizontal and vertical matrix over the whole area (holding the probe in different orientations at 90o to each other for each direction), then concentrating on the areas with the strongest signals.1.1.2 Batch and mask-shrink problemsSome batches of ICs with the same type numbers and manufacturers can have different EMC performance.Semiconductor manufacturers are always trying to improve the yields they get from a silicon wafer, and one way of doing this is to mask-shrink the ICs so they are smaller. Mask-shrunk ICs can have significantly different EMC performance, because smaller devices means:• less energy is required (in terms of voltage, current, power or charge) to control the internal transistors, which can mean lowered levels of immunity• thinner oxide layers, which can mean less immunity to damage from ESD, surge, or overvoltage• lower thermal capacity of internal transistors can mean higher susceptibility to electrical overstress• faster operation of transistors, which can mean higher levels of emissions and higher frequencies of emissions.Large users can usually arrange to get advance warnings of mask-shrinks so they can buy enough of the ‘old’ ICs to keep them in production while they find out how to deal with the changed EMC from the new mask-shrunk IC.It is possible to perform simple goods-in checks of IC EMC performance to see whether a new batch has different EMC performance, for whatever reason. This helps discover problems early on, and so save money.Alternatively, sample-based EMC testing in serial manufacture is required to avoid shipping non-compliant or unreliable products, but it is much more costly to detect components with changed EMC performance this way than it is at goods-in.1.1.3 IC sockets are badIC sockets are very bad for EMC, and directly soldered surface-mount chips (or chip and wire, or similar direct chip termination techniques) are preferred. Smaller ICs with smaller bondwires and leadframes are better, with BGA and similar styles of chip packaging being the best possible to date. Often the emissions and susceptibility of non-volatile memory mounted on sockets (or, worse still, sockets containing battery backup) ruin the EMC of an otherwise good design. Field-programmable low-profile SMD non-volatile memory ICs soldered direct to the PCB are preferred.Motherboards with ZIF sockets and spring-mounted heatsinks for their processors (to allow easy upgrading) are going to require additional costs on filtering and shielding, even so it will help to choose surface-mounted ZIF sockets with the shortest lengths of internal metalwork for their contacts.1.1.4 Circuit techniques• Level detection (rather than edge-detection) preferred for control inputs and keypresses.Use level detection ICs for all control inputs and keypresses. Edge detecting ICs are very sensitive to high-frequency interference such as ESD. (If control signals need to use such very high rates that they need to use edge-detecting devices, they should be treated for EMC as for any other high-speed communication link.)• Use digital edge-rates that are as slow and smooth as possible should be used wherever possible, especially for long PCB traces and wired interconnections (without compromising skew limits).Where skew is not a problem very slow edges should be used (could be ‘squared-up’ with Schmitt gates where locally necessary).• On prototype PCBs allow for control of logic edge speed or bandwidths (e.g. with soft ferrite beads, series resistors, RC or Tee filters at driven ends).Many IC data books don’t specify their output rise or fall times at all (or only specify the maximum times, leaving typical rates unspecified). Because it is often necessary to control unwanted harmonics, it is advisable to make provision for control of logic edge speed or bandwidths, (on prototype PCBs at least).Series resistors or ferrite beads are usually the best way to control edge rates and unwanted harmonics, although R-C-R tee filters can also be used and may be able to give better control of harmonics where transmission lines are used. (simple capacitors to ground can increase output transient currents and increase emissions.)• Keep load capacitance low.This reduces the output current transient when the logic state changes over and helps to reduce magnetic field emissions, ground bounce, and transient voltage drops in the ground plane and power supply, all important issues for EMC.• Fit pull-ups for open-collector drivers near to their output devices, using the highest resistor values that will work.This helps reduce the current loop area and the maximum current, and so helps to reduce magnetic field emissions. However, this could worsen immunity performance in some situations, so a compromise may be needed.• Keep high speed devices far away from connectors and wires.Coupling (e.g. crosstalk) can occur between the metallisation, bond wires, and lead frame inside an IC and other conductors nearby. These coupled voltages and currents can greatly increase CM emissions at high frequencies. So keep high speed devices away from all connectors, wires, cables, and other conductors. The only exception is high-speed connectors dedicated to that IC(e.g. motherboard connectors).When a product is finally assembled, flexible wires and cables inside may lie in a variety of positions. Ensure that no wires or cables can lie near any high-speed devices. (Products without internal wires or cables are usually easier to make EMC compliant anyway.)A heatsink is an example of a conductor, and clearly can’t be located a long way away from theIC it is to be cooling. But heatsinks can suffer from coupled signals from inside an IC just like any other conductor. The usual technique is to isolate the heatsink from the IC with a thermal conductor (the thicker the better as long as thermal dissipation targets are met), then ‘ground’ the heatsink to the local ground plane with many very short connections (the mechanical fixings can often be used).• A good quality watchdog that ‘keeps on barking’ is required.Interference often occurs in bursts lasting for tens or hundreds of milliseconds. A watchdog which is supposed to restart a processor will be no good if it allows the processor to be crashed or hung permanently by later parts of the same burst that first triggered the watchdog. So it is best if the watchdog is an astable (not a monostable) that will keep on timing out and resetting the microprocessor until it detects a successful reboot. (Don’t forget that the watchdog’s timeout period must be longer than the processor’s rebooting time.)AC-coupling of the watchdog input from a programmable port on the micro helps ensure reliable watchdog operation. For more on watchdogs, see section 7.2.3 in [1].• An accurate power monitor is needed (sometimes called a ‘brownout’ monitor).Power supply dips, dropouts interruptions, sags, and brownouts can make the logic’s DC rail drop below the voltage required for the correct operation of logic ICs, leading to incorrect functioning and sometimes over-writing areas of memory with corrupt instructions or data. So an accurate power monitor is required to protect memory and prevent erroneous control activity.Simple resistor-capacitor ‘power-on reset’ circuits are almost certainly inadequate.• Never use programmable watchdogs or brownout monitors.Because programmable devices can have their programs corrupted by interference, programmable devices must not be used for watchdog or power monitor functions.• Appropriate circuit and software techniques also required for power monitors and watchdogs so that they cope with most eventualities, depending on the criticality of the product, (not discussed further in this series of articles).• High quality RF bypassing (decoupling) of power supplies is vital at every power or reference voltage pin of an IC (refer to Part 5 of this series).• High quality RF reference potential and return-current planes (usually abbreviated to ‘ground planes’) are needed for all digital circuits (refer to Part 5 of this series).• Use transmission line techniques wherever the rise/fall time of the logic signal edge is shorter than the “round trip time” of the signal in the PCB track (transmission lines are described in detail in the 5th article in this series).Rule of thumb: round trip time equals 13ps for every millimetre of track length. For best EMC it may be necessary to use transmission line techniques for tracks which are even shorter than this rule of thumb suggests.• Asynchronous processing is preferred.Asynchronous (naturally clocked) techniques have much lower emissions than synchronous logic, and much lower power consumption too. ARM have been developing asynchronous processors for many years, and other manufacturers are now beginning to produce asynchronous products.One of the limitations on designing asynchronous ICs was the lack of suitable design tools (e.g.timing analysers). But at least one asynchronous IC design tool is now commercially available. Some digital ICs emit high level fields from their own bodies, and often benefit from being shielded by their own little metal box soldered to the PCB ground plane. Shielding at PCB level is very low-cost, but can’t always be applied to devices that run hot and need free air circulation.Clock circuits are usually the worst offenders for emissions, and their PCB tracks will be the most critical nets on a PCB, requiring component layout to be adjusted to minimise clock track length and keep each clock track on one layer with no via holes.When a clock must travel a long distance to a number of loads, fit a clock buffer near the loads so the long track (or wire) has smaller currents in it. Where relative skew is not a problem clock edges in the long track should be well-rounded, even sine-waves, squared up by the buffer near the loads.1.1.5 Spread-spectrum clockingSo-called "spread-spectrum clocking" is a recent technique that reduces the measured emissions, although it doesn't actually reduce the instantaneous emitted power so could still cause the same levels of interference with some fast-responding devices. It modulates the clock frequency by 1 or 2% to spread the harmonics and give a lower peak measurement on CISPR16 or FCC emissions tests. The reduction in measured emissions relies upon the bandwidths and integration time constants of the test receivers, so is a bit of a trick, but has been accepted by the FCC and is in common use in the US and EU. The modulation rates in the audio band so as not to compromise clock squareness specifications.Figure 2 shows an example of an emission improvement for one clock harmonic.Debate continues about the possible effects of spread-spectrum clocking on complex digital ICs with the suppliers claiming no problems and some pundits still urging caution, but at least one major manufacturer of high-quality PC motherboards is using this technique as standard on new products. Spread-spectrum clocking should not be used for timing-critical communications links, such as Ethernet, Fibre channel, FDDI, ATM, SONET, and ADSL.Most of the problems with emissions from digital circuits are due to synchronous clocking. Asynchronous logic techniques (such as the AMULET microprocessors being developed by Prof. Steve Furber’s group at UMIST) will dramatically reduce the total amount of emissions and also achieve a true spread-spectrum instead of concentrating emissions at narrow clock harmonics.1.2 Analogue components and circuit design1.2.1 Choosing analogue componentsChoosing analogue components for EMC is not as straightforward as for digital because of the greater variety of output waveshapes. But as a general rule for low emissions in high-frequency analogue circuits: slew rates, voltage swings, and output drive current capability should be selected for the minimum necessary to achieve the function (given device and circuit tolerances, temperature, etc.).But the biggest problem for most analogue ICs in low-frequency applications is their susceptibility to demodulating radio frequency signals which are outside their linear band of operation, and there are few if any data sheet specifications which can act as a guide for this. Specifications and standards for immunity testing of ICs are being developed, and in the future it may be possible to buy ICs which have EMC specifications on their data sheets.Different batches, second-sourced, or mask-shrunk analogue ICs can have significantly different EMC performance for both emissions and immunity. It is important to control these issues by design, testing, or purchasing to ensure continuing compliance in serial manufacture, and some suitable techniques were described earlier (section on choosing digital ICs).Manufacturers of sensitive or high-speed analogue parts (and data converters) often publish EMC or signal-to-noise application notes for circuit design and/or PCB layout. This usually shows they havesome care for the real needs of their customers, and may help tip the balance when making a purchasing decision.1.2.2 Preventing demodulation problemsMost of the immunity problems with analogue devices are caused by RF demodulation.Opamps are very sensitive to RF interference on all their pins, regardless of the feedback schemes employed (see Figure 3).All semiconductors demodulate RF. Demodulation is more common problem for analogue circuits, but can produce more catastrophic effects in digital circuits (when software gets corrupted).Even slow opamps will happily demodulate interference up to cellphone frequencies and beyond, as shown by the real product test results of Figure 4. To help prevent demodulation, analogue circuits need to remain linear and stable during interference. This is a particular problem for feedback circuits. Test the stability and linearity of the feedback circuit by removing all input and output loads and filters, then injecting very fast-edged (<1ns risetime) square waves into inputs (and possibly into outputs and power supplies, via small capacitors). The test signal amplitude is set so that the output pk-pk is about 30% maximum, to prevent clipping. The test signal’s fundamental frequency should be near the centre of the intended passband of the circuit.。
