LabVIEW

第一章LabVIEW简介LabVIEW是美国国家仪器公司(National Instruments Co)开发的一种图形化的编程环境。

其名称含义为实验室虚拟仪器工作平台(Lab oratory V irtual I nstrument E ngineering W orkbench)。

作为一种方便的数据采集和仪器控制开发软件,它可工作于Macintoshe 、Sun SPARC工作站、HP9000/700系列工作站以及PC机等各种机型,可运行于Windows 3.1、Windows9x/2000、Windows NT、UNIX等多系统下,是一种灵活有效的仪器控制和数据分析软件系统。

LabVIEW程序使用虚拟仪器(V irtual I nstrument,缩写为VI)的概念。

它是指一台计算机和连接外部的端口(计算机的COM口,LPT口或内插板)在软件控制下可完全模拟替代传统的仪器。

因VI功能完全是由软件定义,故在硬件系统不变的情况下,用户可通过软件开发自行改变或扩充仪器的功能,实现自己的特殊要求,或用一套硬件系统实现多种仪器的功能,从而使虚拟仪器VI不但比传统仪器更灵活有效,而且也更经济。

VI的核心就是LabVIEW程序,所以在LabVIEW中,所有程序均称之为VI程序,不管它是否通过端口和外界进行通讯。

每个VI程序均可作为一个功能模块被重复使用,因而使用LabVIEW来开发和扩展程序极为方便。

LabVIEW编程语言同常规的程序语言不同,它采用更易使用和理解的图形化程序语言-G语言(Graphical programming language)。

G语言使用图标代替常规的一条或一组语句来实现一个功能,通过各功能图标间的逻辑连接实现程序功能。

其编程过程不是书写一行行语句,而是连接一个个代表一定功能的图标,其程序编制过程简单,不涉及复杂功能实现的算法,易于掌握。

同时,因为其编程过程基于可重复使用的功能模块,故可方便地使用由专业人员编制提供的专业级别的功能模块,开发出专业水平的程序。

LabVIEWLabVIEW is a highly productive graphical programming language for building data acquisition an instrumentation systems.With LabVIEW, you quickly create user interfaces that give you interactive control of your software system. To specify your system functionality,you simply assemble block diagrams - a natural design notation for scientists and engineers. Tis tight integration with measurement hardware facilitates rapid development of data acquisition ,analysis,and presentation bVIEW contains powerful built -in measurement analysis and a graphical compiler for optimum performance. LabVIEW is available for Windows 2000/NT/Me/9x, Mac OS, Linux, Sun Solaris, and HP-UX, and comes in three different development system options.Faster DevelopmentLabVIEW accelerates development over traditional programming by 4 to 10 times! With the modularity and hierarchical structure of LabVIEW, you can prototype ,design, and modify systems in a short amount of time. You can also reuse LabVIEW code easily and quickly in other applications.Better InvestmentUsing a Lab VIEW system, each user has access to a complete instrumentation laboratory at less than the cost of a single commercial instrument. In addition, user configurable LabVIEW systems are flexible enough to adapt to technology changes, resulting in a better bong-term investment.Optimal PerformanceAll LabVIEW applications execute at compiled speed for optimal performance. With the LabVIEW Professional Development System or Application Builder, you can build stand-alone executables or DLLs for secure distribution of your code. You can even create shared libraries or DLLs to call LabVIEW code from other programming languages.Open Development EnvironmentWith the open development environment of LabVIEW, you can connect to other applications through ActiveX, the Web, DLLs, shared libraries, SQL(for databases), DataSocket, TCP/IP,and numerous other e LabVIEW to quickly create networked measurement and automation systems that integrate the latest technologies in Web publishing and remote data sharing. LabVIEW also has driver libraries available for plug-in data acquisition, signal conditioning , GPIB,VXI,PXI, computer-based instruments,serial protocols, image acquisition, and motion control. In addition to the LabVIEW development systems, National Instruments offers a variety of add-on modules and tool sets that extend the functionality of LabVIEW .This enables you to quickly build customizable, robust measurement and automation systems.LabVIEW Datalogging and Supervisory Control ModuleFor high channel count and distributed applications, the LabVIEW Datelogging and Supervisory Control Module provides a complete solution. This module delivers I/O management, event logging and alarm management, distributed logging, historical and real-time trending, built-in security, configurable networking features, OPC device connectivity, and over 3,300 built-in graphics.LabVIEW Real-TimeFor applications that require real-time performance, National Instruments offers LabVIEWReal-Time. LabVIEW Real-Time downloads standard LabVIEW code to a dedicated hardware target running a real-time operating system independent from Windows.LabVIEW Vision Development ModuleThe LabVIEW Vision Development Module is for scientists, automation engineers,and technicians who are developing LabVIEW machine vision and scientific imaging applications. The LabVIEW Vision Development Module includes IMAQ Vision, a library of vision functions, and IMAQ Vision Builder, an interactive environment for vision applications. Unlike any other vision products, IMAQ Vision Builder and IMAQ Vision work together to simplify vision software development so that you can apply vision to your measurement and automation applications.Countless ApplicationsLabVIEW applications are implemented in many industries worldwide including automotive, telecommunications, aerospace, semiconductor, electronic design and production, process control, biomedical, and many others, Applications cover all phases of product development from research to design to production and to service. By leveraging LabVIEW throughout your organization you can save time and money by sharing information and software.Test and MeasurementLabVIEW has become an industry-standard development tool for test and measurement applications. With Test Stand, LabVIEW-based test programs, and the industry's largest instrument driver library, you have a single, consistent development and execution environment for your entire system.Process Control and Factory AutomationLabVIEW is used in numerous process control and factory automation applications.Many scientists and engineers look to LabVIEW for the high speed, high channel count measurement and control that graphical programming offers.For large, complex industrial automation and control applications, the LabVIEW Data logging and Supervisory Control Module provides the same graphical programming as LabVIEW, but is designed specifically for monitoring large numbers of I/O points, communicating with industrial controllers and networks, and providing PC-based control.Machine Monitoring and ControlLabVIEW is ideal for machine monitoring and predictive maintenance applications that need deterministic control, vibration analysis, vision and image processing, and motion control. With the LabVIEW platform of products including LabVIEW Real-Time for real-time deterministic control and the LabVIEW Data logging and Supervisory Control Module, scientists and engineers can create powerful machine monitoring and control applications quickly and accurately.Research and AnalysisThe integrated LabVIEW measurement analysis library provides everything you need in an analysis package. Scientists and researchers have used LabVIEW to analyse and compute real results for biomedical, aerospace, and energy research applications, and in numerous other industries. The available signal generation and processing, digital filtering, windowing, curve-fitting, For specialized analysis, such as joint time-frequency analysis, wavelet,and model-based spectral analysis, LabVIEW offers the specially designed Signal Processing Toolset.The Sound and Vibration Toolset offers octave analysis, averaged and nonaveraged frequency analysis, transient analysis, weighted filtering, and sound-level measurement, and more.Draw Your Own SolutionWith LabVIEW, you build graphical programs called virtual instruments (VIs) instead of writing text-based programs. You quickly create front panel user interfaces that give you the interactive control of your system. To add functionality to the user interface, you intuitively assemble block diagrams- a natural design notation for engineers and scientists.Create the Front PanelOn the front panel of your VI, you place the controls and data displays for your system by selecting ob jects from the Controls palette, such as numeric displays, meters, gauges, thermometers, LEDs, charts,and graphs.When you complete and run your VI,you use the front panel to control your system whether you move a slide, zoom in on a graph, or enter a value with the keyboard.Construct the Graphical Block DiagramTo program the VI, you construct the block diagram without worrying about the syntactical details of text-based programming languages. You do this by selecting objects (icons) from the Functions palette and connecting them together with wires to transfer data among block diagram objects. These objects include simple arithmetic functions, advanced acquisition and analysis routines, network and file I/O operations, and more.Dataflow ProgrammingLabVIEW uses a patented dataflow programming model that frees you from the linear architecture of text-based programming languages. Because the execution order in LabVIEW is determined by the flow of data between nodes,and not by sequential lines of text,you can create block diagrams that execute multiple operations in parallel. Consequently, LabVIEW is a multitasking system capable of running multiple execution threads and multiple VIs in parallel.Modularity and HierarchyLabVIEW VIs are modular in design, so any VI can run by itself or as part of another VI. You can even create icons for your own VIs, so you can design a hierarchy of VIs that serve as application building blocks. You can modify, interchange, and combine them with other VIs to meet your changing application needs.Graphical CompilerIn many applications, execution speed is critical. LabVIEW is the only graphical programming system with a compiler that generates optimized code with execution speeds comparable to compiled C programs. You can even use the LabVIEW profiler to analyse and optimize time-critical operations. Consequently, you increase your productivity with graphical programming without sacrificing execution speed.Measurements and MathematicsLabVIEW includes a variety of other measurement analysis tools. Examples include curve fitting, signal generation, peak detection, and probability and statistics. Measurement analysis functions can determine signal characteristics such as DC/RMS levels, total harmonic distortion (THD),impulse response, frequency response, and cross-power spectrum. LabVIEW users can also deploy numerical tools for solving differential equations, optimization, root finding, and other mathematical problems.In addition, you can extend these built-in capabilities by entering MATLAB or HIQ scripts directly in your LabVIEW programs. For charting and graphing, you can rely on the built-in LabVIEW 2D and 3D visualization tools. 2D tools include features such as autoscaling X and Y ranges, reconfigurable attributes (point/line styles, colors, and more)andcursors, Microsoft Windows users can employ OpenGL-based 3D graphs and then dynamically rotate, zoom, and pan these graphs with the mouse.Development SystemThe LabVIEW Professional Development System facilitates the development of high-end, sophisticated instrumentation systems for developers working in teams, users developing large suites of VIs, or programmers needing to adhere to stringent quality standards.Built on the Full Development System, the Professional Development System also includes the LabVIEW Application Builder for building stand-alone executables and shared libraries (DLLs)and creating distribution kits. In addition, the development system furnishes source code control tools and offers utilities for quantitatively measuring the complexity of your applications. With graphical differencing, you can quickly identify both cosmetic and functional differences between two LabVIEW applications.We include programming standards and style guides that provide direction for consistent LabVIEW programming methodology. The system also contains quality standards documents that discuss the steps LabVIEW users must follow to meet internal regulations or FDA approval. The Professional Development System operates on Windows 2000/NT/Me/9x,Mac OS, HP-UX, and Linux.LabVIEW Full Development SystemThe LabVIEW Full Development System equips you with all of the tools you need to develop instrumentation systems. It includes GPIB, VISA, VXI, RS-232, DAQ, and instrument driver libraries for data acquisition and instrument control. The measurement analysis add DC/RMS measurements, single tone analysis, harmonic distortion analysis, SINAD analysis, limit testing, signal generation capabilities, signal processing, digital filtering, windowing, curve fitting, statistics, and a myriad of linear algebra and mathematical functions. The development system also provides functions for direct access to DLLs, ActiveX, and other external code. Other features of the system include Web publishing tools, advanced report generation tools, the ability to call MATLAB and HiQ scripts, 3D surface, line, and contour graphs, and custom graphics and animation. The Full Development System operates on Windows 2000/NT/Me/9x, Mac OS, HP-UX, and Linux.LabVIEW Base PackageUse the LabVIEW Base Package, the minimum LabVIEW configuration, for developing data acquisition and analysis, instrument control, and basic data presentation.

虚拟仪器 (VI) 的概念
虚拟仪器[1](virtual instrument)是基于计算机的仪器。计算机和仪器的密切结合是目前仪器发展的一个重要方向。粗略地说这种结合有两种方式,一种是将计算机装入仪器,其典型的例子就是所谓智能化的仪器。随着计算机功能的日益强大以及其体积的日趋缩小,这类仪器功能也越来越强大,目前已经出现含嵌入式系统的仪器。另一种方式是将仪器装入计算机。以通用的计算机硬件及操作系统为依托,实现各种仪器功能。虚拟仪器主要是指这种方式。上面的框图反映了常见的虚拟仪器方案。 虚拟仪器[1]实际上是一个按照仪器需求组织的数据采集系统。虚拟仪器[1]的研究中涉及的基础理论主要有计算机数据采集和数字信号处理。目前在这一领域内,使用较为广泛的计算机语言是美国 NI 公司的 LabVIEW[2]。 虚拟仪器的起源可以追溯到20世纪70年代,那时计算机测控系统在国防、航天等领域已经有了相当的发展。PC机出现以后,仪器级的计算机化成为可能,甚至在 Microsof t公司的 Windows 诞生之前,NI公司已经在Macintosh计算机上推出了LabVIEW2.0 以前的版本。对虚拟仪器和 LabVIEW [2]长期、系统、有效的研究开发使得该公司成为业界公认的权威。目前LabVIEW 的最新版本为 LabVIEW2009,LabVIEW 2009 为多线程功能添加了更多特性,这种特性在 1998 年的版本 5 中被初次引入。使用 LabVIEW 软件,用户可以借助于它提供的软件环境,该环境由于其数据流编程特性、LabVIEW Real-Time 工具对嵌入式平台开发的多核支持,以及自上而下的为多核而设计的软件层次,是进行并行编程的首选。 普通的 PC 有一些不可避免的弱点。用它构建的虚拟仪器[1]或计算机测试系统性能不可能太高。目前作为计算机化仪器的一个重要发展方向是制定了VXI 标准,这是一种插卡式的仪器。每一种仪器是一个插卡,为了保证仪器的性能,又采用了较多的硬件,但这些卡式仪器本身都没有面板,其面板仍然用虚拟的方式在计算机屏幕上出现。这些卡插入标准的 VXI 机箱,再与计算机相连,就组成了一个测试系统。VXI 仪器价格昂贵,目前又推出了一种较为便宜的 PXI 标准仪器。

DC Voltage Drop: Below full load, the input to output DC Voltage Drop is controlled to be an essentially constant voltage which appears between the –IN and –OUT terminals. In overload the DC voltage drop will rise as current increases. A few tens of millivolts appears between the +IN and +OUT terminals. Care should be taken not to connect IN and OUT terminals (i.e. through scope probe returns, grounds, etc.), as attenuation will be adversely affected.

Note that there is also a limit to the other type of devices of which often multiple areconnected: PV Inverters. Up to three or four three phase inverters can typically be monitored ona CCGX. Higher power CPU devices can monitor more.2.Though the CCGX has no built-in WiFi that functionality can easily be added by attaching a USB-WiFi dongle. See CCGX Manual, section 1.4.2 for details.3.The built-in WiFi in the Venus GX has a very low signal strength - unfortunately. It is strong enough to connect to a phone, tablet or laptop in order to access setup and monitoring. But to connect the Venus GX to the internet either use the built-in Ethernet port or add a USB-WiFi dongle. See CCGX Manual, section 1.4.2 for details. Make sure the Venus GX is running v2.06 or later - early shipments of Venus GX units ran v2.05.4.The hardware of the Venus GX and Octo GX includes a built-in Bluetooth Smart chipset which hasn't proved satisfactory. Bluetooth Smart for GX devices is coming soon but will not use built-in chipsets.5.Larger SD memory cards (SDXC) are not supported. SD cards can be used for two purposes: 1.Logging data, see this section in the ccgx manual for details.2.Updating firmware, see this section in the ccgx manual for detials.6.The second CANbus port is accessible via the GND, CAN-H and CAN-L terminals. Note that the port is not Isolated. See Settings → Services for configuring that port.7.The programmable relay can be set to act as an alarm relay, automatic genset start stop, or an on/off switch, and is controlled via the GUI and/or ModbusTCP.8.In the Venus GX hardware there are two relays - at present only one of them is available for use.The tank level inputs are resistive and should be connected to a resistive tank sender. Victron 9.does not supply tank senders. The tank level ports can each be configured to work with either European (0 - 180 Ohm); or US tank senders (240 - 30 Ohm).The Cerbo GX has four temperature terminals, and the Venus GX has two. They can be used to 10.measure & monitor all kinds of temperature-inputs. Temperature senders are not included. The required sensor is ASS000001000 - Temperature Sensor QUA/PMP/Venus GX. (Note that this is not the same as the BMV temperature accessory.)11.Octo GX comes with a small Wifi antenna. You may remove and replace it with any other Wifiantenna having an RP-SMA connector.12.Requires the CANvu GX IO Extender and wiring kit13.The 5V output on the Venus GX can be used to power, for example, a USB hub. Note that its output is not current limited or otherwise protected, and it shares the internal power supply in the Venus GX: overdrawing from it will result in shutdown(s) of the Venus GX. It isrecommended to install a fuse for prevention.14.Though some early batches of the Maxi GX, MultiPlus-II GX and EasySolar-II GX all have a dual set of RJ-45 sockets labelled VE.Can, this port is actually a BMS-Can port. It can only be used to connected to managed batteries such as Freedomwon, BYD, Pylontech, BlueNova, MG Energy Systems and others, at 500kbps. The hardware does not meet the requirements for a VE.Can port; and thus it is not possible to use to port to connect Victron products such as theSmartSolar VE.Can MPPT product range. Note that for a while Venus OS firmware did allow to select the VE.Can function and other baudrates. The result will be unreliable, and therefor they have been updated to lock into BMS-Can only at 500kbps.15.A BMS-Can port is a port dedicated to be used for connecting managed batteries, such asFreedomwon, BYD, Pylontech, BlueNova, MG Energy Systems and others, only. It is not possible to connect Victron VE.Can products to that port. To connect such managed battery, use our special cables, and see documentation here. Connect the side labelled 'VE.Can' into the BMS-Can/VE.Can port on the GX Device. And connect the other side to the battery. The baudrate of a BMS-Can port is fixed to 500kbps.16.The GX Touch 50 connects to the Cerbo GX using a single cable; fixed permanently to the GX Touch 50, which on the other end splits into a USB and a connector for the video signal. Bothneed to be inserted into the Cerbo GX, taking one of the three USB ports. The USB part of the cable is used to power the GX Touch 50. The cable is 2 meters in length; and can not beextended in length.17.The Bluetooth feature of the Cerbo GX allows to configure its WiFi and Ethernet settings from within VictronConnect.18.The secondary CAN port, available on some GX devices as per table above, can be configured to be used as a BMS-Can port, as well as other profiles. For details, see manual.DIN rail mounting requires additional accessory - DIN35 Adapter.19.。

VI视觉识别系统设计简介

VI视觉识别系统设计简介

VI视觉识别系统设计简介V I即(V i s u a l I d e n t i t y),通译为视觉识别系统,是C I S系统最具传播力和感染力旳部分。

是将C I旳非可视内容转化为静态旳视觉识别符号,以无比丰富旳多样旳应用形式,在最为广泛旳层面上,进行最直接旳传播。

设计到位、实行科学旳视觉识别系统,是传播企业经营理念、建立企业著名度、塑造企业形象旳迅速便捷之途。

在品牌营销旳今天,没有V I设计对于一种现代企业来说,就意味着它旳形象将沉没于商海之中,让人辨别不清;就意味着它是一种缺乏灵魂旳盈利机器;就意味着它旳产品与服务毫无个性,消费者对它毫无眷恋;就意味着团体旳松散和低落旳士气。

V I设计一般包括基础部分和应用部分两大内容。

其中,基础部分一般包括:企业旳名称、标志设计、标识、原则字体、原则色、辅助图形、原则印刷字体、禁用规则等等;而应用部分则一般包括:标牌旗帜、办公用品、公关用品、环境设计、办公服装、专用车辆等等。

一种优秀旳V I设计对一种企业旳作用应在于:A、在明显地将该企业与其他企业辨别开来旳同步又确立该企业明显旳行业特性或其他重要特性,保证该企业在经济活动当中旳独立性和不可替代性;明确该企业旳市场定位,属企业旳无形资产旳一种重要构成部分;B、传达该企业旳经营理念和企业文化,以形象旳视觉形式宣传企业;C、以自己特有旳视觉符号系统吸引公众旳注意力并产生记忆,使消费者对该企业所提供旳产品或服务产生最高旳品牌忠诚度;D、提高该企业员工对企业旳认同感,提高企业士气。

V I设计旳基本原则:V I旳设计不是机械旳符号操作,而是以M I为内涵旳生动表述。

因此,V I设计应多角度、全方位地反应企业旳经营理念。

A、风格旳统一性原则B、强化视觉冲击旳原则C、强调人性化旳原则D、增强民族个性与尊重民族风俗旳原则E、可实行性原则:V I设计不是设计师旳异想天开而是规定具有较强旳可实行性。

假如在实行性上过于麻烦,或因成本昂贵而影响实行,再优秀旳V I设计也会由于难以贯彻而成为空中楼阁、纸上谈兵。

LabVIEW2012基本介绍

LabVIEW2012基本介绍

LabVIEW 2012 基本介绍一.LabVIEW环境基础知识LabVIEW程序又称虚拟仪器,或VI,其外观和操作模拟真实的物理仪器,例如示波器和万用表。

LabVIEW拥有一整套工具用于采集、分析、显示和存储数据,以及解决用户编写代码过程中可能出现的问题。

当您创建一个新的VI时,您可以看到两个窗口—前面板窗口和程序框图。

前面板打开新VI或现有VI时,将出现VI的前面板窗口。

前面板窗口是VI的用户界面。

图1为前面板窗口的范例。

控件选板控件选板包括用于创建前面板的输入控件和显示控件。

通过选择查看»控件选板,或在前面板窗口中右键单击空白处,您可通过前面板窗口访问控件选板。

控件选板被分成多种类别,用户可以根据各自需要显示部分或者全部类别。

图2显示了所有控件选板类别,并展开了新式类别。

图2.控件选板显示或隐藏类别(子选板),点击―自定义‖按钮,并选择更改可见选板。

输入控件和显示控件每个VI都包含一个前面板,您可以将它视为用户界面进行设计。

当您从别的程序框图调用VI时,您也可以使用前面板,传输输入、接收输出。

将输出控件和显示控件放置在VI前面板上,创建一个VI 的用户界面。

当您将前面板作为用户界面交互时,您可以通过修改控件提供输入,并在显示控件中查看结果。

输入控件决定输入,显示控件显示输出。

输入控件通常是旋钮、按钮、转盘、滑块和字符串。

输入控件仿真仪器的输入装置,为VI的程序框图提供数据。

显示控件通常是图形、图表、LED灯和状态字符串。

显示控件仿真仪器的输出装置,显示程序框图获取或生成的数据。

图1中有两个控件:测量次数和延迟(秒)。

有一个显示控件:XY 坐标图,称为温度图。

用户可以为测量次数和延迟(秒)控件改变输入值。

还可在温度图上看到VI生成的值。

VI基于程序框图中的代码生成显示控件值。

每个输入控件和显示控件都有与其相关的数据类型。

例如,水平滑动杆延迟(秒)是数值型数据类型。

最常用的数据类型为数值型、布尔型和字符串型。
