0.引言随着计算机技术、大规模集成电路技术和通讯技术的飞速发展，仪器技术领域发生了巨人的变化，美国于1986 年首先提出基于计算机技术的虚拟仪器(Virtual lnstruments 简称Ⅵ)的概念，把虚拟测试技术带入新的发展时期，随后研制和推出了基于多种总线系统的虚拟仪器。
虚拟仪器就是在通用计算机上加上软件和硬件，使得使用者在操作这台计算机时，就好象在操作一台自己设计的专用的传统电子仪器。
它可代替传统的测量仪器，如示波器、逻辑分析仪、信号发生器、频谱分析仪等；可集成于自动控制、工业控制系统；可自由构建成专有仪器系统。
它由计算机、应用软件和仪器硬件组成。
无论哪种虚拟仪器系统, 都是将仪器硬件搭载到笔记本电脑、台式PC或工作站等各种计算机平台(甚至可以是掌上电脑) 上，加上应用软件而构成的[1]。
虚拟仪器通过软件将计算机硬件资源与仪器硬件有机的融合为一体，从而把计算机强大的计算处理能力和仪器硬件的测量、控制能力结合在一起，大大缩小了仪器硬件的成本和体积，并通过软件实现对数据的显示、存储以及分析处理。
1.虚拟仪器发展历史及现状LabVIEW( Laboratory Virtual Instrument Engineering Work bench，实验室虚拟仪器工程平台) 是由美国NI公司( National Instruments ，国家仪器公司) 创立的一个功能强大而又灵活的仪器和分析软件应用开发工具，在实验测量、工业自动化和数据分析领域有着重要作用。

labview的基本构成
labview的基本构成LabVIEW（Laboratory Virtual Instrument Engineering Workbench）是一种图形化编程环境，主要用于测量和控制系统的设计。
LabVIEW的基本构成包括以下几个关键元素：1. 前面板（Front Panel）:•用户界面：前面板是LabVIEW程序的用户界面。
它是用户与程序交互的地方，包括控件（如按钮、滑块、图表）和指示器（如图形、数值显示）。
•控件和指示器：控件用于接收用户输入，而指示器用于显示程序输出或中间结果。
2. 图形程序（Block Diagram）:•数据流图：图形程序是LabVIEW的核心，用于实现程序的功能。
它是一个数据流图，其中各个图元表示不同的函数或操作。
连接这些图元的线表示数据流的方向。
•节点和连接线：图形程序由节点（图元）组成，节点执行特定的操作。
连接线表示数据的流向，沿着连接线传递数据。
3. 函数和VI（Virtual Instrument）:•函数：LabVIEW中的函数是基本的操作单元，执行特定的任务，如数学运算、逻辑判断等。
• VI： VI是LabVIEW中的虚拟仪器，可以包含一个或多个前面板和图形程序。
VI可用于将程序模块化，实现可重用的代码。
4. 控制面板（Control Palette）:•控制和显示元素：控制面板是LabVIEW中包含各种控制和显示元素的工具箱。
用户可以从控制面板中拖拽这些元素到前面板，用于构建用户界面。
5. 工具栏（Toolbar）:•编辑和运行：工具栏包含各种工具，如编辑工具、运行工具等，用于编辑程序和执行程序。
6. 项目（Project）:•项目资源：项目视图允许用户组织和管理LabVIEW项目，包括VI文件、数据文件、图标等。
项目视图使得对项目中的所有资源进行集中管理变得更加方便。
这些基本构成元素共同形成LabVIEW的整体框架，LabVIEW的独特之处在于其图形化编程环境，使得用户可以通过直观的方式设计、测试和部署测量和控制系统。
labview的使用方法
labview的使用方法LabVIEW（Laboratory Virtual Instrument Engineering Workbench）是一种LabVIEW （Laboratory Virtual Instrument Engineering Workbench）是一种图形化编程语言，主要用于数据采集、仪器控制、数据分析和测试等方面。
以下是使用LabVIEW的基本步骤：1. 安装LabVIEW软件：首先需要从官方网站下载并安装LabVIEW软件。
安装完成后，启动LabVIEW。
2. 创建新项目：在LabVIEW启动界面中，选择“新建”或“打开”一个已有的项目。
如果创建新项目，可以选择不同的模板，如“VI（Virtual Instrument）”、“Control Design”等。
3. 设计前面板（Front Panel）：前面板是用户与程序交互的界面，可以放置各种控件（如按钮、滑动条、图表等）来显示数据和接收用户输入。
在左侧的“控件”面板中选择所需的控件，然后将其拖放到前面板上进行布局。
4. 编写程序代码（Block Diagram）：在右侧的“块图”面板中编写程序代码。
LabVIEW使用图形化的编程方式，将各种功能模块以图标的形式表示，通过连线连接各个模块来实现程序逻辑。
常用的功能模块包括数学运算、数据处理、信号处理、文件操作等。
5. 调试和运行程序：在编写完程序代码后，需要进行调试以确保程序的正确性。
可以使用断点、单步执行等功能进行调试。
调试完成后，点击工具栏上的“运行”按钮或按F5键运行程序。
6. 保存和导出项目：在完成程序设计和调试后，需要将项目保存为.vi文件。
此外，还可以将程序导出为其他格式，如可执行文件（.exe）、动态链接库（.dll）等。
7. 部署和发布程序：将生成的可执行文件或动态链接库部署到目标计算机上，即可实现程序的功能。
如果需要将程序发布给其他用户，可以将项目打包成安装包或生成Web服务等形式。

In this paper, the VI technology is applied to the test and measurement of instrument current transformer (TA). By using the LabVIEW, the TA accuracy calibrator was developed. This virtual T.4 calibrator can automatically measure the accuracy of T.4 and can indicate the ratio error and phase error curves. The tests and calibration for the TA show that the virtual TA calibrator can be used in place of the traditional calibrator and is much better than the traditional one. Keywords：Instrument current transformer (TA), TA calibrator, Virtual Instruments, LabVIEW.I. INTRODUCTIONSince 1992 the VXIbus Rev.1.4standard was established by the United States and LabVIEW was presented by the National Instruments co.(Nl), the Virtual Instrument (VI) have lain the foundation for its commercial use. The main characteristic of Virtual Instrument is that it makes instruments by software. Most of the traditional instrument can be developed by VI. The VI is a real instrument made by the personal computer.The Instrument current transformer (TA) is widely used in all kinds of current measurement and it has the functions of protection, isolation and extending the measuring range. With the rapid development of computer measurement and control technology, and with the sequent emergence of current transformer and transducer, there is an increasing number of current transformers with high accuracy and low secondary current. The standard TA secondary current is usually 1A or 5A: some non-standard TA secondary current may be 0 1A or lower. Although we have the technique to make this kind of calibrator by means of hardware such as single chip computer and electroniccircuit, DSP and so on, it will cost too much money for these no-standard calibrator and will take too much time and the calibrator made by these hardware mill not be satisfactory in both function and practicality for designing all kinds of new TA.The calibrator that adopts VI technology not only can meet the requirements of the traditional one but also can satisfy customers with such advantages as multi-functions, convenience, and high ratio between performance and cost. The experiment results indicate that the virtual calibrator can provide excellent condition for TA measurement and design. The VI technology and personal computer must be widely used in the area of calibration on instrument transformer.Ⅱ. THE WORKING PRINCIPLE OF TA CALIBRATOR The error of TA includes ratio error and phase error. The measuring of the error of TA or the calibration of the accuracy of TA usually applies differential measuring method. The method needs a standard TA except the measured TA and a TA calibrator. There is the same turn ratio between the standard and measured T4 and the standard TA's accuracy should be 2 levels higher than the measured one. The calibrator function lies in forming comparison circuits, measuring, and showing the error at all range. The comparison circuit, also referred to the difference measuring principle circuit, is showed in Fig. 1. By measuring the voltage on I, and Rd, calculate the corresponding current. Then the calibrator can indicate the error.When a TA has the same turn ratio between the primary and secondary winding, the self-comparison circuit could be used and is shown in Fig.2. In the figures, TA0 and TAX are standard and TA being measured respectively. Np and Ns are primary and secondary winding turns. ip and io, id, i, are primary currentsecondary standard current, secondary error current, secondary current of TA being measured respectively. Ro and R,R, are secondary winding's resistance ofstandard TA, error currentdetecting resistance, burden resistance ofTA being measured respectively. To and K, Tb. T, are voltage sampling points which can calculate the current In this paper, only voltage between K and T, voltage between Tb and T, are being measured and they represent the voltage on R, and R, respectively.In general, the TA calibrator's principle of the sample resistance should be:1）it can not affect the accuracy of the comparison circuit. In the ideal condition R, and Rd should be 0, but it can not be sampled. So there must be sample resistance, in this paper, R, as shown in Fig, is used;1）the magnitude of the sample resistance should make the sampled standard currentand error current in pro rata and should not have too much difference. The sampled resistance is set by experiment: R, is the secondary standard current sampling resistance andcan be 0.1-0.50, R, is the error current sampling resistance and canbe, R, is the burden resistance and it depends on the TA being measured. E$ sampling the voltage uo and U, on R, and R, respectively, the ratio error and phase error are showed on the LED through some process and calculations.According to the TA error's phase diagram, when io is maximum, the value of id is the ratio error; when io changes from negative to positive and equals to 0, the value of id is the phase error. For the same principle, the relationship is equal to the voltage signal U, and ud. showed in Fig.3. a and b is represent the ratio error and phase error separately. the TA's real ratio error C and phase error 6 can be found out through proper calculation,Where U, is the amplitude of uo The T.4 calibrator doesn't need very high accuracy. 1% to 3% error for the calibrator is enough. Because of the difference measuring principle, the error is the read error of calibrator, that is, the TA's error's error being measured. But the calibrator needs to have a suitable enlargement factor. The calibrator maximum enlargement factor through all channels should be 1000 times.III. THE PRINCIPLE OF VIRTUAL CA LIBRATORThe Virtual Instrument consists of three parts: the external comparison circuit (showed in Fig.1 or Fig.2), data acquisition card (PCI-6023) installed in the PC and the VI program by LabVIEW Then, after the two channels' signal U, and ud come into the PC through the ADC, the rest of the work is done by the software. In this paper we use voltage U, on R, substitute for U, approximatively. The virtual calibrator's work flow chart is shown as follow:1) Set the essential initial values of the virtual calibrator;2) Press the start button to start to work, adjusting the voltage regulator and changing the primarycurrent, let the ratio between primary current and the rated current change from10% to 120%;3) The VI program willgroup the voltage signal U, and ud , then use the digital filter to eliminatethe harmonic:4) Calculatethe root-mean-square (RMS) value of tlx and 14, find out the amplitude of 21;5) Calculate the RMS valve of io (substitute for f, ), i, and the ratio between io and it's rated current and show the results.6) Find out the a and b showed in Fig. 3, calculate the ratio error and phase error and show the results.7) Set the L times loop, record and show the errors acquired by every time,8) Show and print all the results of calibration.9）Stop.The front panel of the virtual calibrator has the Controls, indictor and Switch. The function of Controls is to set the initial value before it works, The function of the Indictor is to show at1 kinds of needed values, including digital, curve and diagram etc.. 'The switch decides the start and stop of the virtual calibrator.Of course, to change the measuring range, the operator needs to adjust the voltage regulator and change the primary current. This operation is necessary like that of the traditional calibration, but the recording for the error in any range is done by the virtual calibration. This confirms the accuracy of recording and relieves the operator's work. The use of virtual calibrator is most interesting.The controls of virtual calibrator include:1) Setting the two sampling (analogue input) channels;2) Setting the magnitude of sampling resistance in the comparison circuit;3) Setting the secondary rated current of measured TA;4) Setting the number of sampling of error curve;The Indictor of virtual calibrator has:1) Showing ratio and phase error, ratio between the primary current and the rated ones in digital;2) Showing ratio and phase error, ratio between the primary) current and the rated ones Incurvesand diagram, where the curveinclude the active sampling points and function fitting curves;3) Showing the error for the ratio between the primary current and the rated current from 10% to 1 20°%;4) Showing the waveform of standard and error current, digital value of amplitude;5) Showing of digita1 RMS value the standard and error current;6) Showing the pole of TA in the comparison circuit;The above shows that the function of virtual calibrator is greatly expended that of the traditional ones. 7111s kind of calibrator is not only convenient to use, but also makes the performance of the calibrator much better. From the function that shows the waveform, we canfindout if there are some harmonics in the current, and confirm the accuracy for the calibrator.IV. EXPERIMENTThe virtual calibrator is mainly characterized by the flexibility compared with the traditional ones. Although the front panel has many functions, they can be easily extended by the user. So the virtual calibrator is of important value for the non-standard TA calibration.In the experiment, the primary current produce by a step-up current transformer and its' current controlled by a voltage regulator. Through fitting the comparison circuit, the measuring range of the virtual calibrator canbe set in any value. This paper gives SA and 0.1A two kinds of TA’s calibration experiment. The parameter and method, results are presented below.A. 5A TA experimentThe parameter of TA being measured is:Because of the 1:1 ratio of turn, the calibration for it doesn't need standard TA. The calibration circuit show in Fig2 We can apply self ca libration method to measure it’s accuracy. The results are presented in the Ftg.4 and Fig5 and show that this TA's accuracy can be defined as 0.5 degree.B. 0.1A TA experimentThe parameter of standard TA:From the Fig4 and 5, the accuracy of the TA being measured can be defined as 0.5 degree. In the experiment, the input signal of virtual calibrator should be properly grounded to avoid the disturbance. The sampling resistance in the comparison circuit should use precise ones and with no induction.V. CONCLUSIONSThe VI technique is one of the new scientific and technique productions. The appearance of VI is called“Revolution of Measuring and Control Technology”. According to the development of the software and hardware for computers, the VI t~hn01Ogy will have more developing space. The VIS will replace most of the traditional ones in the 21th century. With its flexibility, the virtual calibrator can measure any kind of T.4 including standard and non-standard ones. But the traditional calibrator can not measure most of the non-standard TA. It can record and save, display the data automatically. The method presented in this paper gives a new way to make he TA calibration. The main characteristics of the virtual calibrator are:1) Flexibility, virtual calibrator is mainly made of LabVIEW software and can be easilymodifiedby rewrite some software;2.) Multi function, VI is designed on PC. It has waveform indictor, parameter controls and so on.At the time wecalibrating a TKs accuracy, these functions can indicate many information such as waveform quality and so on;3) Convenience to carry and use;4) High efficiency and accuracy.;5) High ratio between performance and cost;6) For multiple use in one PC.7) It can record and save, display the calibration data automatically.基于LabVIEW的电流互感器校验仪Xin Ai Hai Bao T.H.

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 andscientific 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.

The available signal generation and processing, digital filtering, windowing, curve-fitting, For specialized analysis, such as joint time-frequency analysis, wavelets, 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 objects 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 and subVIs 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 evenuse the LabVIEW profiler to analyze 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) and cursors. Microsoft Windows users can employ OpenGL-based 3D graphs and then dynamically rotate, zoom, and pan these graphs with the mouse.Complex Measurements Made EasyDespite the complexity of the underlying algorithms that implement these functions, you will find them easy to use. For example, a set of built-in measurement functions uses the new waveform data type to accept real-world, time-domain signal inputs directly from DAQ hardware and report results ready for charting, graphing, or the next stage of signal processing.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, orprogrammers needing to adhere to stringent quality standards.
