智能控制系统中英文资料对照外文翻译文献附录一：外文摘要The development and application of Intelligence controlsystemModern electronic products change rapidly is increasingly profound impact on people's lives, to people's life and working way to bring more convenience to our daily lives, all aspects of electronic products in the shadow, single chip as one of the most important applications, in many ways it has the inestimable role. Intelligent control is a single chip, intelligent control of applications and prospects are very broad, the use of modern technology tools to develop an intelligent, relatively complete functional software to achieve intelligent control system has become an imminent task. Especially in today with MCU based intelligent control technology in the era, to establish their own practical control system has a far-reaching significance so well on the subject later more fully understanding of SCM are of great help to.The so-called intelligent monitoring technology is that:" the automatic analysis and processing of the information of the monitored device". If the monitored object as one's field of vision, and intelligent monitoring equipment can be regarded as the human brain. Intelligent monitoring with the aid of computer data processing capacity of the powerful, to get information in the mass data to carry on the analysis, some filtering of irrelevant information, only provide some key information. Intelligent control to digital, intelligent basis, timely detection system in the abnormal condition, and can be the fastest and best way to sound the alarm and provide usefulinformation, which can more effectively assist the security personnel to deal with the crisis, and minimize the damage and loss, it has great practical significance, some risk homework, or artificial unable to complete the operation, can be used to realize intelligent device, which solves a lot of artificial can not solve the problem, I think, with the development of the society, intelligent load in all aspects of social life play an important reuse.Single chip microcomputer as the core of control and monitoring systems, the system structure, design thought, design method and the traditional control system has essential distinction. In the traditional control or monitoring system, control or monitoring parameters of circuit, through the mechanical device directly to the monitored parameters to regulate and control, in the single-chip microcomputer as the core of the control system, the control parameters and controlled parameters are not directly change, but the control parameter is transformed into a digital signal input to the microcontroller, the microcontroller according to its output signal to control the controlled object, as intelligent load monitoring test, is the use of single-chip I / O port output signal of relay control, then the load to control or monitor, thus similar to any one single chip control system structure, often simplified to input part, an output part and an electronic control unit ( ECU )Intelligent monitoring system design principle function as follows: the power supply module is 0~220V AC voltage into a0 ~ 5V DC low voltage, as each module to provide normal working voltage, another set of ADC module work limit voltage of 5V, if the input voltage is greater than 5V, it can not work normally ( but the design is provided for the load voltage in the 0~ 5V, so it will not be considered ), at the same time transformer on load current is sampled on the accused, the load current into a voltage signal, and then through the current - voltage conversion, and passes through the bridge rectification into stable voltage value, will realize the load the current value is converted to a single chip can handle0 ~ 5V voltage value, then the D2diode cutoff, power supply module only plays the role of power supply. Signal to the analog-to-digital conversion module, through quantization, coding, the analog voltage value into8bits of the digital voltage value, repeatedly to the analog voltage16AD conversion, and the16the digital voltage value and, to calculate the average value, the average value through a data bus to send AT89C51P0, accepted AT89C51 read, AT89C51will read the digital signal and software setting load normal working voltage reference range [VMIN, VMAX] compared with the reference voltage range, if not consistent, then the P1.0 output low level, close the relay, cut off the load on the fault source, to stop its sampling, while P1.1 output high level fault light, i.e., P1.3 output low level, namely normal lights. The relay is disconnected after about 2minutes, theAT89C51P1.0outputs high level ( software design), automatic closing relay, then to load the current regular sampling, AD conversion, to accept the AT89C51read, comparison, if consistent, then the P1.1 output low level, namely fault lights out, while P1.3 output high level, i.e. normal lamp ( software set ); if you are still inconsistent, then the need to manually switch S1toss to" repair" the slip, disconnect the relay control, load adjusting the resistance value is: the load detection and repair, and then close the S1repeatedly to the load current sampling, until the normal lamp bright, repeated this process, constantly on the load testing to ensure the load problems timely repair, make it work.In the intelligent load monitoring system, using the monolithic integrated circuit to the load ( voltage too high or too small ) intelligent detection and control, is achieved by controlling the relay and transformer sampling to achieve, in fact direct control of single-chip is the working state of the relay and the alarm circuit working state, the system should achieve technical features of this thesis are as follows (1) according to the load current changes to control relays, the control parameter is the load current, is the control parameter is the relay switch on-off and led the state; (2) the set current reference voltage range ( load normal working voltage range ), by AT89C51 chip the design of the software section, provide a basis for comparison; (3) the use of single-chip microcomputer to control the light-emitting diode to display the current state of change ( normal / fault / repair ); specific summary: Transformer on load current is sampled, a current / voltage converter, filter, regulator, through the analog-digital conversion, to accept the AT89C51chip to read, AT89C51 to read data is compared with the reference voltage, if normal, the normal light, the output port P.0high level, the relay is closed, is provided to the load voltage fault light; otherwise, P1.0 output low level, The disconnecting relay to disconnect the load, the voltage on the sampling, stop. Two minutes after closing relay, timing sampling.System through the expansion of improved, can be used for temperature alarm circuit, alarm circuit, traffic monitoring, can also be used to monitor a system works, in the intelligent high-speed development today, the use of modern technology tools, the development of an intelligent, function relatively complete software to realize intelligent control system, has become an imminent task, establish their own practical control system has a far-reaching significance. Micro controller in the industry design and application, no industry like intelligent automation and control field develop so fast. Since China and the Asian region the main manufacturing plant intelligence to improve the degree of automation, new technology to improve efficiency, have important influence on the product cost. Although the centralized control can be improved in any particular manufacturing process of the overall visual, but not for those response and processingdelay caused by fault of some key application.Intelligent control technology as computer technology is an important technology, widely used in industrial control, intelligent control, instrument, household appliances, electronic toys and other fields, it has small, multiple functions, low price, convenient use, the advantages of a flexible system design. Therefore, more and more engineering staff of all ages, so this graduate design is of great significance to the design of various things, I have great interest in design, this has brought me a lot of things, let me from unsuspectingly to have a clear train of thought, since both design something, I will be there a how to design thinking, this is very important, I think this job will give me a lot of valuable things.中文翻译：智能控制系统的开发应用现代社会电子产品日新月异正在越来越深远的影响着人们的生活，给人们的生活和工作方式带来越来越大的方便，我们的日常生活各个方面都有电子产品的影子，单片机作为其中一个最重要的应用，在很多方面都有着不可估量的作用。

智能楼宇自动化系统引言楼宇自动化系统也叫建筑设备自动化系统(BuildingAutomationSystem简称BAS)，是智能建筑不可缺少的一部分，其任务是对建筑物内的能源使用、环境、交通及安全设施进行监测、控制等，以提供一个既安全可靠，又节约能源，而且舒适宜人的工作或居住环境。
2 楼宇自动化系统的组成与基本功能建筑设备自动化系统通常包括暖通空调、给排水、供配电、照明、电梯、消防、安全防范等子系统。
根据我国行业标准，BAS又可分为设备运行管理与监控子系统和消防与安全防范子系统，如图所示。
一般情况下，这两个子系统宜一同纳入BAS考虑，如将消防与安全防范子系统独立设置，也应与BAS监控中心建立通信联系以便灾情发生时，能够按照约定实现操作权转移，进行一体化的协调控制。
建筑设备自动化系统的基本功能可以归纳如下：(1)自动监视并控制各种机电设备的起、停，显示或打印当前运转状态。
(2)自动检测、显示、打印各种机电设备的运行参数及其变化趋势或历史数据。
(3)根据外界条件、环境因素、负载变化情况自动调节各种设备，使之始终运行于最佳状态。
(4)监测并及时处理各种意外、突发事件。
(5)实现对大楼内各种机电设备的统一管理、协调控制。
(6)能源管理：水、电、气等的计量收费、实现能源管理自动化。
(7)设备管理：包括设备档案、设备运行报表和设备维修管理等。
3 楼宇自动化控制系统的原理楼控系统采用的是基于现代控制理论的集散型计算机控制系统，也称分布式控制系统(Distributedcontrol systems简称DCS)。
它的特征是“集中管理分散控制”，即用分布在现场被控设备处的微型计算机控制装置(DDC)完成被控设备的实时检测和控制任务，克服了计算机集中控制带来的危险性高度集中的不足和常规仪表控制功能单一的局限性。
安装于中央控制室的中央管理计算机具有CRT显示、打印输出、丰富的软件管理和很强的数字通信功能，能完成集中操作、显示、报警、打印与优化控制等任务，避免了常规仪表控制分散后人机联系困难、无法统一管理的缺点，保证设备在最佳状态下运行。
以下介绍与分布控制系统相关的几个概念。
3.l 直接数字控制系统(DDC)直接数字控制系统(Direct Digital Control简称DDC)如图2所示。
计算机通过模拟量输入通道(AI)和开关量输入通道(DI)采集实时数据，然后按照一定的规律进行计算，最后发出控制信号，并通过模拟量输出通道(AO)和开关量输出通道(DO)直接控制生产过程。
因此DDC系统是一个闭环控制系统，是计算机在工业生产过程中最普遍的一种应用方式。
DDC系统中的计算机直接承担控制任务，因而要求实时性好、可靠性高和适应性强。
3．1．1 直接数字控制系统的组成直接数字控制系统主要由过程输入通道、过程控制计算机、过程输出通道三部分组成。
过程输入通道由模拟量输入和数字量输入两部分组成。
模拟量输入通道由变送器、采样开关、放大器、A／D转换器和接口电路组成。
其中变送器的作用是将非电量信号变换成标准电信号，可将温度、压力、流量变换成0-10mA或4-20mA 的直流电信号，它是通过A／D转换器来实现的。
—数字量输入通道由开关触点、光电耦合器和接口电路组成，反映生产过程的通／断状态的触点信号，经过光电耦合器和接口电路变换成数字信号送给计算机。
过程控制计算机直接承担运算和控制任务，首先通过过程输入通道采集被控对象的各种参数信号，再根据预定的控制规律(如PID)进行运算，然后向被控对象发出控制信号，再通过输出通道直接控制调节阀等执行机构。
过程输出通道由模拟量输出和数字量输出两部分组成。
前者把计算机输出的数字控制信号转换成模拟电压或电流信号，再经过放大器去驱动调节阀等执行器实现对生产过程的控制。
这一部分由接口电路、D／A转换器，放大器和执行器组成。
后者把计算机输出的开关信号，经放大器去驱动电磁阀和继电器执行器，它由接口电器、光电耦合器、放大器和执行器组成。
3．1．2 直接数字控制系统的基本算法按照偏差的比例(P)、积分(I)和微分(D)进行控制，是连续系统中技术成熟、应用最为广泛的一种基本规律，将PID控制规律离散化并在计算机上实现，可以方便地利用已积累的成熟技术，而且可以在被控对象的数学模型或参数不很清楚的情况下，经过在线整定达到满意的效果。
因此，将模拟调节规律离散化的数字PID算法，已被工业过程计算机控制系统普遍采用，成为DDC系统的基本算法。
数字PID控制算法，模拟量调节器的理想PID算式为式中e(t)——偏差(设定值与实际输出值之差)u(t)——控制量Kp——比例放大系数Ti一积分时间常数Td——微分时间常数写成传递函数形式为了能在计算机上实现，必须将连续形式的微分方程化为离散形式的差分方程。
设了为采样周期(与系统时间常数相比，T足够小)，k为采样序号(k=0，1，2，……)，可用矩形法计算而积以差分代替微分式中e(k)——第k次采样所得偏差值e(k-1)——第(k-1)次采样所得偏差值u(k)——第k时刻的控制量上式中的采样周期T越小(与系统时间常数比较而言)，则被控过程与连续控制过程越接近，又称为“准连续控制”。
3．2 分布式控制系统的体系结构分布式控制系统(Distributed Control Systems简称DCS)20世纪于70年代中期出现并迅速发展起来，它将计算机技术、控制技术、图形显示技术和通信技术汇集于一体，可对分散在现场的设备进行控制，又可方便地集中管理、操作，与以往的控制系统相比，既避免了单台计算机集中控制的不足，又克服了常规仪表人机交互困难的缺点。
分布式控制系统的多台微型计算机取代了集中控制系统的单台计算机，从体系结构上分散了危险性，提高了可靠性。
其基本结构功能如图3所示，图中现场控制站、数据采集站、工程师站、操作员站、监控计算机和管理计算机通过数据通信网络被有机地结合起来，组成分级分布控制系统。
3．2．1 分布式控制系统的数据通信网络数据通信网络是分布式控制系统的支柱。
整个分布式控制系统的结构，实质上是一个网络结构，现场控制站、数据采集站、工程师站、操作员站、监控计算机等都是这个网络上的“节点”，都含有CPU和网络接口，它们都有自己特定的网络地址(节点号)，可以通过网络发送和接收数据，网络中的各节点处于平等地位，既能共享资源，又不相互依赖，形成既有统一指挥，又使危险分散的功能结构，网络的架构区具有极大的伸缩性，可扩性很强，可以满足分布式控制系统扩充与升级的需要，十分灵活、方便。
(1)控制网络特点分布式控制系统的通信网络不同于通用计算机网络，与一般的通信网络比较，它有如下特殊要求：①有高可靠性和安全性，要求传递的信息绝对准确、可靠，为此常采用冗余技术、后备措施和自诊断功能。
如：控制站采用双CPU板，双I／0板等。
②具有良好的实时性。
③对环境适应性强。
(2)网络拓扑结构建筑设备自动化系统常用的有总线网和环网，在两种结构中任意两节点通信可直接通过网络进行，各节点处于平等地位。
(3)网络通信协议组成建筑设备自动化系统，必须有一种大家都能接受并且共同遵守的工作语言来实现相互之间的对话，这就是数据通信协议标准。
用于建筑自动化控制网络的BACnet协议由物理层、数据链路层、网络层和应用层组成，或相当于开放系统互联参考模型(OSI)的第一、二、三、七层协议其中：ARCnet 为令牌总线网，数据传输速率为2．5-20bit／s，有良好的实时性。
MS／TP是一种主／从令牌传递数据链路层技术，允许使用EIA-485硬件。
BACnet实现了不同生产厂家自控系统之间进行通信的技术，即从一个“岛”到另一个“岛”之间进行相互联系的技术。
5 结束语楼宇自动化控制技术在我国还是一个新兴的技术领域，随着更多智能建筑的出现，将有更加先进的技术补充到这一领域中，使这一技术更加成熟、完善。
