Virtual instrument is the United States N

2、ational Instruments Corporation (Nl) out of the concept of modern computer technology and instrumentation technology in-depth integration of the product. Virtual Instrument virtual There are two levels of meaning: 1. A virtual control panel, two virtual test and measurement and analysis. Virtual ins

3、trument is characterized by . NIs withdrawal from a professionalgraphical programming software to design and development of virtual instruments, that is, Labiew. LabVIEW, short for Laboratory Virtual Instrument Engineering Workbench, is a programming environment in which you create programs using a

4、graphical notation (connecting functional nodes via wires through which data flows); in this regard, it differs from traditional programming languages like C, C+, or Java, in which you program with text. However, LabVIEW is much more than a programming language. It is an interactive program developm

5、ent and execution system designed for people, like scientistsand engineers,who need to program as part of their jobs. The LabVIEW development environment works on computers running Windows, Mac OS X, or Linux. LabVIEW can create programs that run on those platforms, as well as Microsoft Pocket PC, M

6、icrosoft Windows CE, Palm OS, and a variety of embedded platforms, including Field Programmable Gate Arrays (FPGAs), Digital Signal Processors(DSPs), and microprocessors. Using the very powerful graphical programming language that many LabVIEW users affectionately call G (for graphical), LabVIEW can

7、 increase your productivity by orders of magnitude. Programs that take weeks or months to write using conventional programming languages can be completed in of ideas, general programming, or even teaching basic programming concepts. Labiew feature continuously enriched and powerful, Labiew used for

8、data acquisition and control, data analysis and data representation, so that engineers and scientists to take full advantage of PC functions, quickly and easily complete their own power to make. Labview main features can be summarized as follows: a graphical environment for two instruments into a bu

9、ilt-in program compiler, so that run faster three flexible means of four supports multiple debugging platform 5 supports DDE functions. Labiew years of development from 1986 to now, support multiple popular operating systems,Labview main course of development are as follows: 1.1983 years in April, L

10、abview Development System in the United States Austin, Texas, the successful development of 2.佃85-year in May, NI introduced the Labview Beta test version 3.佃86-year in October, NI company officially released the Labview1.0 for Macintosh version of the 4.佃90-year in January, Labview2.0 came 5.1992-y

11、ear in August in support of SUN Solaris workstation and PC-Labview version available 6.1993-year in January, Labview3.0 version is developed 7.1998-year in February, Labview5.0 version available, this version is a milestone in the the Labview 7 series, introduced a new data type - Dynamic Data Types

12、 9.2022 years, Labview 8 version of the interview, the version of the specific distributed, intelligent outstanding features 10.2022, the 20th anniversary edition of Labview 8.20 an interview. 8.21 is the Chinese version of 11.2022-year in August, Labview8.5 available 12.2022-year in August, Labview

13、8.6 version available After 20 years of continuous innovation, development, Labview to rely on the concept of a new and unique advantages, and efficient and powerful, and open the three basic characteristics, and gradually become the industry standard. The above describes the characteristics of Labv

14、iew and development, described below Typically, a virtual instrument design steps are as follows: (1). In the design window, place the front panel controls, front panel using the tool template development window, the corresponding tools, fromthe control template and place a good accesscontrol is nee

15、ded to carry out parameter setting control properties, stickers text description tag. (2). In the flow chart editing window, place the nodes, frame, in the flow chart editing window, use the tool template correspondingtools, from a functional template and put a good access to the required icon, they

16、 are the flow chart in the nodes , frame. (3). The data flow programming, data flow using the connection tool according to the direction of the port, node, frame in turn connected to data from the source sent to the prescribed purpose terminal operating mode. (4). Run test, when the completion of st

17、ep (a), (2), (3), the front panel procedure and flow chart graphic design program is completed, a virtual instrument basically established, whether to achieve the desired functionality, need to run the test. There are two kinds of test methods. a.Simulation Test: do not use I O interface tests on th

18、e signal data is from array or signal-generating function, resulting emulation signal. b.Measured test: it is through the I O interface to test in experimental tests carried out prior to the virtual instrument unique advantage because of its repeated testing, debugging, and constantly improve the im

19、provement of virtual instrument is extremely convenient, is a traditional instrument can not be used in test methods. .debugging techniques,use the toolbar shortcut Run, of, Step, Breakpoint set to the following steps to program debugging. a.to identify grammatical errors, if there is a syntax error

20、, then when start the Shortcut Bar Run button, the button becomes a broken arrow, the program can not perform. Mouse click on the button, a list will pop up an error window, the window listed in the wrong item, and then click any one of the listed errors, click the Find function button, then the err

21、or object, or the port will be changed bright. b.slow tracking program running, use the shortcut in the toolbars of button, click the button, the button icon becomesclick Run button, the program on a slower speed. The implementation of the code was not grayed out after the implementation of the code

22、 the value of the data stream. This allows the data flow, and track the implementation of the procedures. c.breakpoints and single-step, in order to check the program logic error, you may want to program a block diagram node in a node implementation. Breakpoint tool to use a certain location in the

23、program to suspend program execution, using probes or single-step ways to view the data. d.set the probe, you can view the block diagram by setting the probe to open a connection procedure by a data valu e. (6). data observed, when the inspection observations were found toerror, the mouse click Highlight Execution button, and observe the various nodes in the data stream values. (7). named Save, save the designed I.
