Labview中英文简介
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。

虚拟函数波形发生器中英文资料外文翻译文献The Design of Virtual Function waveform Generator Abstract—In this paper, a Virtual Function Signal Generator is designed Based on Labview. How to design the generator is introduced in detail. The Virtual Function Signal Generator can generate basic wave such as Sine wave, formula wave, white noise etc. The generator has functions like wave showing and date saving in addition. Keywords- Virtual Instrument; Labview;Function Signal GeneratorI. INTRODUCTIONThe function signal generator is applied in great many of fields. Virtual Instrument is a new type of instrument which has especial functions that old one do not have. One VI includes PC, hardware which is particularly designed and special software. Being a graphical programming language Labview is used for date gathering, instrument controlling and date analyzing. How to design virtual function signal generator by Labview is explained in detail in the following paper.II. TOTAL DESIGNAccording to the principle of function signal generator,four parts were designed to compose virtual function signal generator. These four parts are property setting, signal generating, wave showing and date saving.A. Panel of GeneratorIn this system the panel are divided to property setting panel(fig.1) and total structure panel(fig.2) . Main options in the first one are frequency, amplitude, duty cycle and samples etc. about signal. These properties can be set in this panel. Total structure panel just includes four parts that were presented above and some additional parts.Figure 1.Property Set Panel Figure2.Total Structure PanelB. Function about InstrumentsThe Virtual Function Signal Generator can generate basic waves such as Sine wave , special waves like formula wave and some kinds of noise. Signal’s frequency can be regulated delicately or roughly. Property can be reset quickly and be used as subprogram sometimes. Moreover has the generator functions like wave showing and date saving etc.III. SOFTWARE ABOUT VIRTUAL FUNCTION SIGNALGENERATORThe Virtual Function Signal Generator was designed base on Labview 7.0. There are three modules which compose this system: module of property setting, wave generating, wave showing and saving.A. Module of Property SettingFrequency setting and property resetting are two important parts of this module. How to change frequency value multiply is explained in fig.3. Node Selectting is applied repeatedly and skillfully so that data can be input in many channels. Then select data by switch button. So frequency controlling can be designed as real instrument. How to reset property quickly is explained in fig.4.Figure4. Property ResetFigure3. Frequency ControlB. Module of Wave GeneratingThis module is the core of the Virtual Function Signal Generator. Structure CASE is used in this work. By special node many types of waves can be generated. For example, how to generate sine wave is explained in fig.5. The other ones can be generated in similar way.Figure5.Graphical Progranm About Sine Wave GenerateC. Module of Wave Showing and SavingIn fact this module is a composite one which include many functions as operating, applying, debugging, showing etc. Because of lots of acts would be operated though this interface, this interface must be not only practical but also nice. Fig.6 just explained how to solve these problems.Figure6.Graphical Program About TotalIV. CONCLUSIONBeing graphical language, Labview is very strong and easy tool to make system of measure and test. Virtual Function Signal Generator based on Labview has advantages such as having friendly interface, operating easily etc. It can generate many types of function signals which have big range of value of frequency and its output datas can be saved. So it can be applied widely.虚拟函数波形发生器的设计摘要在本次设计中,虚函数信号发生器是基于相位差来设计的。

Labview图形化编程语⾔中英⽂对照外⽂翻译⽂献中英⽂资料外⽂翻译National Instruments LabVIEW: A Programming Environment for Laboratory Automation and Measurement .National Instruments LabVIEW is a graphical programming language that has its roots in automation control and data acquisition. Its graphical representation, similar to a process flow diagram, was created to provide an intuitive programming environment for scientists and engineers. The language has matured over the last 20 years to become a general purpose programming environment. LabVIEW has several key features which make it a good choice in an automation environment. These include simple network communication, turnkey implementation of common communication protocols (RS232, GPIB, etc.), powerful toolsets for process control and data fitting, fast and easy user interface construction, and an efficient code execution environment. We discuss the merits of the language and provide an example application suite written in-house which is used in integrating and controlling automation platforms.Keywords: NI LabVIEW; graphical programming; system integration; instrument control; component based architecture; robotics; automation; static scheduling; dynamic scheduling; databaseIntroductionCytokinetics is a biopharmaceutical company focused on the discovery of small molecule therapeutics that target the cytoskeleton. Since inception we have developed a robust technology infrastructure to support our drug discovery efforts. The infrastructure provides capacity to screen millions of compounds per year in tests ranging from multiprotein biochemical assays that mimic biological function to automated image-based cellular assays with phenotypic readouts. The requirements for processing these numbers and diversity of assays have mandated deployment of multiple integrated automation systems. For example, we have several platforms for biochemical screening, systems for live cell processing, automated microscopy systems, and an automated compound storage and retrieval system. Each in-house integrated system is designed around a robotic arm and contains an optimal set of plate-processing peripherals (such as pipetting devices, plate readers, and carousels) depending on its intended range of use. To create the most flexible, high performance, and cost-effective systems, we have taken the approach of building our own systems in-house. This has given us the ability to integrate the most appropriate hardware and software solutions regardless of whether they are purchased from a vendor or engineered de novo, and hence we can rapidly modify systems as assay requirements change.To maximize platform consistency and modularity, each of our 10 automated platforms is controlled by a common, distributed application suite that we developed using National Instruments (NI) LabVIEW. This application suite described in detail below, enables our end users to create and manage their own process models (assayscripts) in a common modeling environment, to use these process models on any automation system with the required devices, and allows easy and rapid device reconfiguration. The platform is supported by a central Oracle database and can run either statically or dynamically scheduled processes.NI LabVIEW BackgroundLabVIEW, which stands for Laboratory Virtual Instrumentation Engineering Workbench is a graphical programming language first released in 1986 by National Instruments (Austin, TX). LabVIEW implements a dataflow paradigm in which the code is not written, but rather drawn or represented graphically similar to a flowchart diagram Program execution follows connector wires linking processing nodes together. Each function or routine is stored as a virtual instrument (VI) having three main components: the front panel which is essentially a form containing inputs and controls and can be displayed at run time, a block diagram where the code is edited and represented graphically, and a connector pane which serves as an interface to the VI when it is imbedded as a sub-VI.The top panel (A) shows the front panel of the VI. Input data are passed through “Controls” which are shown to the left. Included here are number inputs, a file path box, and a general error propagation cluster. When the VI runs, the “Indicator”outputs on the right of the panel are populated with output data. In this example, data include numbers (both as scalar and array), a graph, and the output of the error cluster. In the bottom panel (B) the block diagram for the VI is shown. The outer case structure executes in the “No Error” case (VIs can make internal errors o r if called as a sub-VI the caller may propagate an error through the connector pane).Unlike most programming languages, LabVIEW compiles code as it is created thereby providing immediate syntactic and semantic feedback and reducing the time required for development and testing.2Writing code is as simple as dragging and droppingfunctions or VIs from a functions palette onto the block diagram within process structures (such as For Loops, or Case Structures) and wiring terminals (passing input values, or references). Unit testing is simplified because each function is separately encapsulated; input values can be set directly on the front panel without having to test the containing module or create a separate test harness. The functions that generate data take care of managing the storage for the data.NI LabVIEW supports multithreaded application design and executes code in an inherently parallel rather than sequential manner; as soon as a function or sub-VI receives all of its required inputs, it can begin execution. In Figure 1b, all the sub-VIs receive the array input simultaneously as soon as the For Loop is complete, and thus they execute in parallel. This is unique from a typical text-based environment where the control flows line by line within a function. When sequential execution is required, control flow can be enforced by use of structures such as Sequences, Events, or by chaining sub-VIs where output data from one VI is passed to the input of the next VI.Similar to most programming languages, LabVIEW supports all common data types such as integers, floats, strings, and clusters (structures) and can readily interface with external libraries, ActiveX components, and .NET framework. As shown in Figure 1b, each data type is graphically represented by wires of different colors and thickness. LabVIEW also supports common configuration management applications such as Visual SourceSafe making multideveloper projects reasonable to manage.Applications may be compiled as executables or as Dynamic Link Libraries (DLLs) that execute using a run-time engine similar to the Java Runtime Environment. The development environment provides a variety of debugging tools such as break-points, trace (trace), and single-step. Applications can be developed using a variety of design patterns such as Client-Server, Consumer-Producer, andState-Machine. There are also UML (Unified Modeling Language) modeling tools that allow automated generation of code from UML diagrams and state diagrams.Over the years, LabVIEW has matured into a general purpose programming language with a wider user base.NI LabVIEW as a Platform for Automation and InstrumentationOur experience creating benchtop instrumentation and integrated automation systems has validated our choice of LabVIEW as an appropriate tool. LabVIEW enables rapid development of functionally rich applications appropriate for both benchtop applications and larger integrated systems. On many occasions we have found that project requirements are initially ill defined or change as new measurements or new assays are developed.. There are several key features of the language that make it particularly useful in an automation environment for creating applications to control and integrate instrumentation, manage process flow, and enable data acquisition.Turnkey Measurement and Control FunctionLabVIEW was originally developed for scientists and engineers .The language includes a rich set of process control and data analysis functions as well as COM, .NET, and shared DLL support. Out of the box, it provides turnkey solutions to a variety of communication protocols including RS232, GPIB, and TCP/IP. Control structures such as timed While Loops allow synchronized and timed data acquisition from a variety of hardware interfaces such as PCI, USB, and PXI. DataSocket and VI ServerDeployment of an integrated system with multiple control computers requires the automation control application to communicate remotely with instrument drivers existing on remote computers. LabVIEW supports a distributed architecture by virtue of enabling seamless network communication through technologies such as VI Server and DSTP (data sockets transfer protocol). DSTP is an application layer protocol similar to http based on Transmission Control Protocol/Internet Protocol (TCP/IP). Data sockets allow easy transfer of data between remote computers with basic read and write functions. Through VI server technology, function calls can be made to VIs residing on remote computers as though they are residing on the local computer. Both Datasockets and VI server can be configured to control accesses privileges.Simple User Interface (UI) ImplementationIn addition to common interface controls such as text boxes, menu rings, and check-boxes, LabVIEW provides a rich set of UI controls (switches, LEDs, gauges, array controls, etc.) that are pertinent to laboratory equipment. These have their origins in LabVIEWs laboratory roots and help in development of interfaces which give scientists a clear understanding of a system's state. LabVIEW supports UI concepts including subpanels (similar to the Multiple Document Interface), splitter bars, and XControls (analogous to OCX controls).Multithreaded Programming EnvironmentThe inherent parallel environment of LabVIEW is extremely useful in the control of laboratory equipment. Functions can have multiple continuous While Loops where one loop is acquiring data rapidly and the other loop processes the data at a much slower rate. Implementing such a paradigm in other languages requires triggering an independent function thread for each process and developing logic to manage synchronization. Through timed While Loops, multiple independent While Loops can be easily synchronized to process at a desired period and phase relative to one another. LabVIEW allows invoking multiple instances of the same function witheach maintaining its own data space. For instance, we could drag many instances of the Mean sub-VI onto the block diagramin Figure 1b and they would all run in parallel, independent of one another. To synchronize or enforce control flow within the dataflow environment, LabVIEW also provides functions such as queues, semaphores, and notification functions.NI LabVIEW Application Example: The Open System Control Architecture (OSCAR)OSCAR is a LabVIEW-based (v7.1) automation integration framework and task execution engine designed and implemented at Cytokinetics to support application development for systems requiring robotic task management. OSCAR is organized around a centralized Oracle database which stores all instrumentation configuration information used to logically group devices together to create integrated systems (Fig. 2). The database also maintains Process Model information from which tasks and parameters required to run a particular process on a system can be generated and stored to the database. When a job is started, task order and parameter data are polled by the Execution Engine which marshals tasks to each device and updates task status in the database in real time. Maintaining and persisting task information for each system has two clear benefits. It allows easy job recovery in the event of a system error, and it also provides a process audit trail that can be useful for quality management and for troubleshooting process errors or problems.Each OSCAR component is distributed across the company intranet and communicates with a central database. Collections of physical devices controlled through OSCAR Instrument packages (OIP) make up systems. Users interact with systems through one of the several applications built on OSCAR. Each application calls the RTM which marshals tasks from the database to each OIP. OSCAR has sets of tools for managing system configurations, creating Process Models, monitoring running processes, recovering error-state systems, and managing plate inventory in storage devices.OSCAR uses a loosely coupled distributed component architecture, enabled in large part by LabVIEWs DSTP and remote VI technologies that allow system control to be extended beyond the confines of the traditional central control CPU model. Any networked computer or device can be integrated and controlled in an OSCAR system regardless of its physical location. This removes the proximity constraints of traditional integrated systems and allows for the utilization of remote data crunchers, devices, or even systems. The messaging paradigm used shares many similarities with current Service Oriented Architectures or Enterprise Service Bus implementations without a lot of required programming overhead or middleware; a centralized server is not required to direct the XML packets across the network. An additional benefit to this loosely coupled architecture is the flexibility in front-end application design. OSCAR encapsulates and manages all functionality related to task execution and device control, which frees the developer to focus on the unique requirements of a given application. For example, an application being created for the purpose of compound storage and retrieval can be limited in scope to requirements such as inventory management and LIMS integration rather than device control, resource allocation, and task synchronization.The OSCAR integration framework consists of multiple components that enable device and system configuration, process modeling, process execution, and process monitoring. Below are descriptions of key components of the framework. Integration PlatformThe Oscar Instrument Package (OIP) is the low level control component responsible for communicating with individual devices. It can support any number of devices on a system (including multiple independent instances of the same type of device) and communicates to the Runtime Manager (RTM) via serialized XMLstrings over DSTP. This allows the device controller and RTM components to exist on separate networked computers if necessary. Additionally, the OIP controller communicates with a device instance via LabVIEW remote VI calls which provide a lower level of distribution and allow the device drivers to exist on a separate networked computer from the controller. At Cytokinetics, we currently support approximately 100 device instances of 30 device types which are distributed across 10 integrated systems.System ManagementAn OSCAR system is a named collection of device instances which is logically represented in the database. The interface for each device (commands and parameters) is stored in the database along with the configuration settings for each device instance (i.e., COM port, capacity). The System Manager component provides the functionality to easily manipulate this information (given appropriate permissions). When a physical device is moved from one system to another, or a processing bottleneck alleviated by addition of another similar device, system configuration information is changed without affecting the processes that may be run on the system.Process ModelingA process model is the logical progression of a sequence of tasks. For example, a biochemical assay might include the following steps (1) remove plate from incubator, (2) move plate to pipettor, (3) add reagent, (4) move plate to fluorescent reader, (5) read plate, and (6) move plate to waste. The Process Modeler component allows the end user to choose functions associated with devices and organize them into a sequence of logical tasks. The resulting process model is then scheduled via a static schedule optimization algorithm or saved for dynamic execution (Fig. 3). Aprocess model is not associated with a physical system, but rather a required collection of devices. This has two importantbenefits: (1) the scientist is free to experiment with virtual system configurations to optimize the design of a future system or the reconfiguration of an existing system, and (2) any existing process model can be executed on any system equipped with the appropriate resources.The top panel (A) shows the Process Schedule Modeler, an application that graphically displays statically scheduled processes. Each horizontal band represents a task group which is the collection of required tasks used by a process; tasks are color coded by device. The bottom panel (B) shows the UI from the Automated Imaging System application. The tree structure depicts the job hierarchy for an imaging run. Jobs (here AIS_Retrieval and AIS_Imaging) are composed of task groups. As the systems runs, the tasks in the task group are executed and their status is updated in the database.Process ExecutionProcess execution occurs by invoking the OSCAR RTM. The RTM is capable of running multiple differing processes on a system at the same time allowing multiple job types to be run in parallel. The RTM has an application programming interface (API) which allows external applications to invoke its functionality and consists of two main components, the Task Generator Module (TGM) and the Execution Engine. External applications invoke an instance of a Process Model through the TGM at which point a set of tasks and task parameters are populated in the OSCAR database. The Execution Engine continually monitors the database for valid tasks and if a valid task is found it is sent to the appropriate device via the OIP. The OSCAR system supports running these jobs in either a static or dynamic mode. For processes which must meet strict time constraints (often due to assay requirements), or require the availability of a given resource, a static schedule is calculated and stored for reuse.The system is capable of optimizing the schedule based on actual task operation times (stored in the database).Other types of unconstrained processes benefit more from a dynamic mode of operation where events trigger the progress of task execution as resources become available in real-time. When operating dynamically, intelligent queuing of tasks among multiple jobs allows optimal use of resources minimizing execution time while allowing for robust error handling.Process MonitoringAll systems and jobs can be monitored remotely by a distributed application known as the Process Monitor. This application allows multiple users to monitor active jobs across all systems for status and faults and provides email notification for fault situations.ConclusionCytokinetics has built and maintains an automation software infrastructure using NI LabVIEW. The language has proven to be a powerful tool to create both rapid prototype applications as well as an entire framework for system integration and process execution. LabVIEW's roots in measurement instrumentation and seamless network communication protocols have allowed systems to be deployed containing multiple control computers linked only via the network. The language continues to evolve and improve as a general purpose programming language and develop a broad user base.。

Access the LabVIEW Help by selecting Help»LabVIEW Help.•LabVIEW Quick Reference Card—Use this card as a reference for information about keyboard shortcuts and help resources.1Getting Started withLabVIEW Virtual InstrumentsLabVIEW programs are called virtual instruments, or VIs, because their appearance and operation imitate physical instruments, such as oscilloscopes and multimeters. LabVIEW contains a comprehensive set of tools for acquiring, analyzing, displaying, and storing data, as well as tools to help you troubleshoot code you write.In LabVIEW, you build a user interface, or front panel, with controls and indicators. Controls are knobs, push buttons, dials, and other input mechanisms. Indicators are graphs, LEDs, and other output displays. After you build the front panel, you add code using VIs and structures to control the front panel objects. The block diagram contains this code.You can use LabVIEW to communicate with hardware such as data acquisition, vision, and motion control devices, as well as GPIB, PXI, VXI, RS232, and RS485 instruments. Building a Virtual InstrumentIn the following exercises, you will build a VI that generates a signal and displays that signal in a graph. After you complete the exercises, the front panel of the VI will look similar to the front panel in the following figure.You can complete the exercises in this chapter in approximately 40 minutes.Figure 1-1. Front Panel of the Acquiring a Signal VIChapter 1Getting Started with LabVIEW Virtual InstrumentsLaunching LabVIEWThe Getting Started window appears when you launch LabVIEW. Use this window to create new projects and open existing files. You also can access resources to expand the capability of LabVIEW and information to help you learn about LabVIEW.The Getting Started window disappears when you open an existing file or create a new file and reappears when you close all open front panels and block diagrams. You also can display the window from the front panel or block diagram by selecting View»Getting Started Window. Opening a New VI from a TemplateLabVIEW provides built-in template VIs that include the subVIs, functions, structures, and front panel objects you need to get started building common measurement applications.Complete the following steps to create a VI that generates a signal and displays it in the front panel window.unch LabVIEW.2.Select File»New to display the New dialog box.3.From the Create New list, select VI»From Template»Tutorial (Getting Started)»Generate and Display. This template VI generates and displays a signal.A preview and a brief description of the template VI appear in the Description section. Thefollowing figure shows the New dialog box and the preview of the Generate and Display template VI.Figure 1-2. New Dialog Box4.Click the OK button to create a VI from the template. You also can double-click the nameof the template VI in the Create New list to create a VI from a template.LabVIEW displays two windows: the front panel window and the block diagram window.5.Examine the front panel window.The user interface, or front panel, appears with a gray background and includes controls and indicators. The title bar of the front panel indicates that this window is the front panel for the Generate and Display VI.Note If the front panel is not visible, you can display the front panel by selectingWindow»Show Front Panel. You also can switch between the front panel windowand block diagram window at any time by pressing the <Ctrl-E> keys. The <Ctrl>key in keyboard shortcuts corresponds to the (Mac OS X) <Command> key or(Linux)<Alt> key.6.Select Window»Show Block Diagram and examine the block diagram of the VI.The block diagram appears with a white background and includes VIs and structures that control the front panel objects. The title bar of the block diagram indicates that this window is the block diagram for the Generate and Display VI.7.On the front panel toolbar, click the Run button, shown below. You also can press the<Ctrl-R> keys to run a VI.A sine wave appears on the graph in the front panel window.8.Stop the VI by clicking the front panel STOP button, shown below.Adding a Control to the Front PanelFront panel controls simulate the input mechanisms on a physical instrument and supply data to the block diagram of the VI. Many physical instruments have knobs you can turn to change an input value.Complete the following steps to add a knob control to the front panel.Tip Throughout these exercises, you can undo recent edits by selecting Edit»Undoor pressing the <Ctrl-Z> keys.1.If the Controls palette, shown in Figure1-3, is not visible in the front panel window, selectView»Controls Palette.Tip You can right-click any blank space in the front panel or the block diagram todisplay a temporary version of the Controls or Functions palette. The Controls orFunctions palette appears with a thumbtack icon in the upper left corner. Click thethumbtack to pin the palette so it is no longer temporary.2.If you are a new LabVIEW user, the Controls palette opens with the Modern palette,shown in the following figure, visible by default. If you do not see the Modern palette, click Modern on the Controls palette to display the Modern palette.Figure 1-3. Controls Palette3.Move the cursor over the icons on the Modern palette to locate the Numeric Controlspalette.When you move the cursor over icons on the Controls palette, the name of the subpalette, control, or indicator appears in a tip strip below the icon.Note Some palette objects display a short name on the palette that is different fromthe name that appears in the tip strip. The short name abbreviates the name of thepalette object so that it fits in the space available on the palette. If you have difficultyfinding a palette object by its short name, use the Search button on the Controls orFunctions palette to find the palette object by name.4.Click the Numeric Controls icon to display the Numeric Controls palette.5.Click the Knob control on the Numeric Controls palette to attach the control to the cursor,and then add the knob to the front panel to the left of the waveform graph.You will use this knob in a later exercise to control the amplitude of a signal.6.Select File»Save As and save the VI as Ac quiring a Signal.vi in an easily accessiblelocation.Changing a Signal TypeThe block diagram has a blue icon labeled Simulate Signal. This icon represents the Simulate Signal Express VI. An Express VI is a component of the block diagram that you can configure to perform common measurement tasks. The Simulate Signal Express VI simulates a sine wave by default.Complete the following steps to change this signal to a sawtooth wave.1.Display the block diagram by pressing the <Ctrl-E> keys or by clicking the block diagram.Locate the Simulate Signal Express VI, shown below. The Simulate Signal Express VI simulates a signal based on the configuration that you specify.2.Right-click the Simulate Signal Express VI and select Properties from the shortcut menuto display the Configure Simulate Signal dialog box. (Mac OS X) Press <Ctrl>-click to perform the same action as right-click.Tip You also can double-click the Express VI to display the Configure SimulateSignal dialog box.3.Select Sawtooth from the Signal type pull-down menu.The waveform on the graph in the Result Preview section changes to a sawtooth wave. The Configure Simulate Signal dialog box should appear similar to the following figure.。

LabVIEW的基本概念和术语解析
LabVIEW的基本概念和术语解析LabVIEW（Laboratory Virtual Instrument Engineering Workbench）是一种由美国国家仪器公司（National Instruments）开发的图形化编程语言和集成开发环境。
它被广泛应用于各种科学和工程领域，用于实时数据采集、信号处理、控制系统设计等。
一、LabVIEW的基本概念1. 虚拟仪器：LabVIEW通过虚拟仪器的概念，将计算机软件与硬件设备相结合，实现了传统仪器的功能。
使用LabVIEW，我们可以创建虚拟仪器（Virtual Instrument），将实验中的传感器、仪器和控制设备的功能模拟成一个虚拟仪器。
虚拟仪器不仅仅是一个图形界面，它还包含了先进的数据处理和分析能力。
通过虚拟仪器，我们可以采集实时数据、分析实验结果，并进行可视化展示。
2. 图形化编程：LabVIEW采用图形化编程语言，即G语言（G Language）。
与传统的文本编程不同，G语言使用图形化的图标和线连接的方式来表示程序的流程和逻辑。
通过图形化编程，我们可以通过拖拽和连接不同的图标来构建程序。
这种方式可以使得程序的结构和逻辑更加直观和易于理解，降低了编程的复杂性。
3. 数据流编程：LabVIEW中的程序被称为虚拟仪器或者VI （Virtual Instrument）。
VI是基于数据流原理工作的，即数据在不同的节点之间流动。
数据流编程使得程序能够以并行的方式工作，每个节点的计算都在数据可用时自动触发。
这种方式可以提高程序的效率和响应速度。
二、LabVIEW的术语解析1. 块图（Block Diagram）：块图是LabVIEW程序的主要视图，用于表示程序的结构和逻辑。
块图由各种图标和线连接组成，展示了数据的流动和处理过程。
2. 前面板（Front Panel）：前面板是LabVIEW程序的用户界面，用于与用户进行交互。
前面板由各种控件和指示器组成，控件用于接收用户的输入，指示器用于显示计算结果或者实时数据。

美国国家仪器公司的LabVIEW ：一种实验室自动化和测量的编程环境美国国家仪器公司的LABVIEW是一种图形化编程语言，它的根源在于自动化控制和数据采集。
其图形化的代表性，类似于过程流程图，它为科学家和工程师提供一个直观的编程环境，在过去20年中成熟历程中，这个语言已经成为一个通用的编程环境。
LABVIEW使得它成为很好的自动化选择环境有几个主要特点，这些措施包括简单的网络通信，交钥匙执行共同的通信协议（RS232 ，GPIB总线等），成为过程控制和数据拟合、快速简便的用户界面的建设和一个有效率的程式码执行环境的强大工具。
我们讨论这种语言的优点，并提供一个例子，在公司内部是用来在整合和控制自动化平台的应用套件的书面。
关键词：NI LABVIEW ;图形化编程;系统集成;仪表控制;基于组件的体系结构;机器人;自动化;静态调度;动态调度;数据库导言cytokinetics是一个侧重于以小分子疗法发现细胞骨架为目标的生物制药公司。
自成立以来，我们形成了一个强大的技术基础设施，以支持我们发现药物的努力。
基础设施能提供以百万计画面显示化合物的能力，每年在测试范围从基于图像细胞检测与表型读出的复合生化检测模仿生物功能的自动化的能力。
要求处理这些数字和多样性的检测已授权部署多个综合自动化系统。
举例来说，我们有几个平台：生化检查，系统的活细胞处理系统，自动显微镜系统，以及一个自动复合存储和检索系统。
每一个在公司内部的综合系统是根据其打算使用范围，围绕着机械臂，并包含一个最佳的一套板加工外设（如移液设备，板读者，carousels ）设计的。
为了创造最灵活，高性能极具成本效益的系统，我们已采取的做法是在内部建设自己的系统。
这给赋予我们整合能力最适当的硬件和软件解决方案，无论是否从供应商购买或工程重新进行，因此我们可以迅速修改系统的检测要求的变化。
最大限度地平台的一致性和模块化，我们每10个自动化平台是由一个共同- 1 -的控制的，我们开发时使用美国国家仪器公司（Ni ）的分布式应用套件LABVIEW。
下面详细说明这个应用套件，使我们的最终用户能够创建和管理自己的过程模型（检测脚本），在一个共同的建模环境中，对任何自动化系统所需的设备使用这些过程模型，并允许容易和快速装置重构。
该平台是支持由一个中央Oracle数据库和可以运行无论是静态或动态预定进程。
NI LABVIEW背景LABVIEW是首次发表在1986年由美国国家仪器公司（德克萨斯州奥斯汀市）的实验室虚拟仪器工程工作台是一个图形化编程语言。
LABVIEW中实现了一个数据范式，其中的代码不是写，而是制定或图样类似流程图（图1）。
执行程序随着连接器电线连接节点处理一起。
每个功能或例行的存储作为一个虚拟仪器，它有三个主要部分组成：前面板，这基本上是一种形式，是一种包含输入和控制，并且可以实时显示，后面板是代码图形被编辑的地方，当它被嵌入作为子VI时，作为接口连接到VI的连接器窗格中。
图1 NI LABVIEW VI例子上面面板（A）表明虚拟仪器的前面板。
输入数据是通过显示在左侧的“控制量”输入的。
这里包括有多少输入，文件路径框，和一般的误差传播集群。
当VI 运行时，“显示量”输出在右边的面板上，该面板被输出数据填充。
在这个例子中，数据包括数字（既作为标和数组），一个图形，和输出错误群集。
在下边的面板作为虚拟仪器的后面板显示出来。
在“没有错误”的情况下，外部条件结构才执行（虚拟仪器通过连接器窗格对可以查出的内部错误或被称作子程序可能提示的错误）。
不同于大多数的编程语言，由于LABVIEW通过自己生成编制代码，从而提供即时的句法和语义的反馈和减少形成和测试所需的时间。
操作规则就像拖放功能或虚拟仪器从功能面板上的框图作为进程结构（如循环，或条件结构）- 2 -和线路终端（通过输入值，或参考）这么简单。
单元测试由于每个功能分别封装而简化;输入值可不必测试包含模块而直接对前面板设定或创建一个单独的测试。
这个功能产生的数据管理存储的数据。
NI LABVIEW以一个固有的并行而非顺序地方式支持多线程应用程序的设计和执行的代码;只要作为一个函数或子VI收到所有其需要的输入，便可以开始执行。
在图1 B中，所有子VI对收到数组输入尽快作为循环完成，因此，它们是并行执行的。
这是独特的从一个典型的基于文本的环境下，由线的一个功能控制流程线。
当需要顺序执行时，控制流可以使用结构执行，如序列，事件，或由链状子VI对那里的输出数据从一个VI传送作为另一个VI的输入。
类似于大多数编程语言，LABVIEW的支持所有常用的数据类型，如整数，浮点，字符串，和集群（结构）及可随时与外部图书馆，ActiveX组件，和NET 框架连接。
正如图1 B所示，每个数据类型通过不同颜色和厚度的电线图形代表。
LABVIEW的也支持常见的配置管理应用，如Visual SourceSafe的决策多媒体开发项目的合理管理。
申请者可被编译成可执行文件或动态链接库（DLL ）表示，执行使用的类似Java Runtime Environment的实时引擎。
开发环境提供了多种调试工具如断点，以动画方式显示数据及其子程序（子VI）的结果以及单步执行。
申请可开发利用各种设计模式，如客户端-服务器，消费者-生产者和状态机。
也有基于UML （统一建模语言）建模工具，允许自动生成的代码从UML的图表和状态图表. 多年来，LABVIEW的已发展成为一个拥有广泛的用户群的通用的编程语言。
NI LABVIEW作为自动化和仪器仪表的一个平台我们创造台式仪表和综合自动化系统的经验，已验证了我们选择的LABVIEW是一种适当的工具。
LABVIEW的快速发展使它成为既适合台式应用和较大的综合系统又有丰富功能的应用软件。
在很多场合我们发现，最初错误的定义或者由于新的测量方法或新的检测方法的发展要求项目改变。
该语言在自动化的环境，创建应用控制和仪器仪表整合，管理流程，使数据采集等有几个使它特别有用主要特点：- 3 -交钥匙工程的测量和控制功能LABVIEW最初是为高级科学家和工程师开发的。
这种语言包括一整套丰富的过程控制和数据分析功能，以及作为COM，.NET并共享DLL的支持。
除此之外，它提供了交钥匙解决方案，以不同的通信协议包括的RS232，GPIB的，和TCP/IP。
控制结构，如延时while循环，允许从各种硬件接口同步和定时，如PCI，11个USB及PXI12采集数据。
DataSocket技术及VI服务器一个集成系统的部署需要多台要求自动化控制应用的控制计算机与存在远程计算机的仪器驱动程序连接。
LABVIEW支持分布式体系结构，凭借有利的无缝网络通信通过技术，如VI服务器和DSTP (数据插口调动协议) 。
DSTP是一个类似于基于传输控制协议/网际协议（TCP / IP ）HTTP的应用层协议。
Data sockets允许远程计算机之间的基本读及写的功能和简单传输数据。
通过VI服务器技术，可以使存放在远程计算机上虚拟仪器就像是存放在本地计算机上一样进行功能调用。
可以配置Datasockets和VI服务器控制访问权限。
简单的用户界面（ UI ）的执行情况在除了共同的控制之外，例如文本框，菜单上的圆环，和复选框，LABVIEW，在相关的实验室设备提供了一整套丰富的UI控件（开关，发光二极管，仪表，数组控制等）。
这些有其起源于LABVIEWS实验室的根源，并帮助在发展中的界面，让科学家们清楚地了解一个系统的状态。
LABVIEW支持用户界面的概念，包括subpanels （类似多文档界面）分配器酒吧，和xcontrols （类似的OCX控件）。
多线程编程环境固有的并行环境的LABVIEW在控制实验室设备是极为有益的.功能可以有多个连续的While循环，而其中一个循环是迅速采集数据，另一个以循环以一个比较慢的速度采集回路数据。
在其他语言实施这样一个范式，需要触发一个独立的线程函数为每个进程和发展的逻辑来管理同步。
通过定时while循环，多个独立的while循环可以很容易地同步的过程在一个理想的时期和阶段进行- 4 -同步的过程。
LABVIEW的允许援引多个相同的功能对于每个包含自己的数据空间实例。
例如，我们在图1b可能拖动许多子VI事例，并且他们能相互独立的运行。
同步或执行控制流与数据流的环境，还提供了LABVIEW的功能，如队列，信号量，和通知功能。
NI LABVIEW应用程序实例：开放式系统控制建筑学(OSCAR) 奥斯卡是一个基于LABVIEW （v7.1 ）自动化集成框架和任务执行引擎设计和实施在cytokinetics支持要求机器人任务管理应用的开发系统。
奥斯卡是围绕着一个用于集中储存逻辑设备共同创造的所有仪器的配置信息的Oracle数据库的综合系统（图2 ）。
该数据库在运行其中的任务和参数所需的运行过程中还保持着过程模型的资料，特别是对系统可以生成并储存到数据库中。
当工作开始，在这个实时性数据库中，任务顺序和参数数据是通过纠察任务每个设备和更新任务的状态执行引擎的。
在系统误差情形下，它允许简单的工作补救，并且它也提供可以是有用于质量管理和为解决困难的过程错误或问题的处理查帐索引。
图2 奥斯卡组成图每个奥斯卡奖的组成部分是分布在整个公司内部网路，并且与中央数据库连接。
对于被OSCAR仪器包裹(OIP)控制的物理设备的组成的系统，用户通过在OSCAR建立的几种应用中的一种与系统交互。
每个从数据库中到每一个OIP纠察任务应用程序的调用叫RTM。
SCAR有套为处理系统布局，创造处理模型，监测连续过程，恢复错误状态系统和处理板材存货的工具在存贮设备。
奥斯卡采用了松散耦合的分布式组件架构，使在大部份由LABVIEW DSTP 和远程VI技术，允许系统控制，以延长超越的传统的中央控制的CPU型号的局限。
在OSCAR系统下，不管它的实际位置如何，任何网络的计算机或设备- 5 -可以集成和受控。
这去除传统集成系统接近度限制并且考虑到远程数据咬碎、设备，甚至系统的运用。
奥斯卡封装和管理的所有功能有关的任务的执行和控制装置，一个特定的应用，释放发展侧重于独特的需求，举例来说，一个正在创建的以应用为目的的复合存储和检索，可以在有限范围的要求，如库存管理和LIMS的整合，而非装置控制，资源分配和任务同步。
OSCAR集成框架包括设备和系统配置、过程建模，流程执行，过程监控的多个组分。
下面是框架的关键部件的描述：集成平台Oscar文书(OIP)是低级控制元件，负责与各自的设备沟通。
它通过被连载的XML串DSTP系统可以支持设备的所有数字(设备的同一个类型的包括多个独立事例)并且沟通对执行时间的管理(RTM) 。
如果需要存在这在分开的网络的计算机允许设备控制器和RTM组成。
