The Design of Med-Frequency Generator
Test System Based on Virtual Instrument
ABSTRACT:As the wide use of electrical machinery,we are stricter on the quality and function of electrical machinery.Therefore,we are stricter on the data collecting technology and processing technology too. traditional instruments and apparatuses cann’t satisfy the demand for production and experiment in many fields.at present,the development of the electronic technology and computering technology can offer a good condition for electrical machinery test system. the combination of technology of the computer and technology of instrument and apparatus produces the virtual instrument ——Testing and analysing technology in collection based on computer, the instrument enters the era of virtual instrument gradually.
In fact, according to the instrument’s demand, virtual instrument organize the data collecting system.By the research of virtual instrument,involve in some basic theories,such as data collecting technology and digital signal processing.At present,in the area of virtual instrument,the LabVIEW was invented by american company IN is one of computer language.It was used more extensive.
LabVIEW(Laboratory Virtual instrument Engineering workbench)is a figure programming language.When we use this language to write programs,we needn’t to write program code,the flow chart was replace program code. It can make better use of the terminology, picture identifier and concept that the technical personnels,scientists and engineers are familiar with. It can improve the work efficiency greatly when we are using it to do things such as principle research, design,test and realizing the equipment system.So it is widely accepted by the industrial fields,academic circles and the research labs.It is also considered as a standard software for data collecting and equipment controlling.
In a word, Med-frequency generator test system based on virtual Instrument is valuable and helpful for the development of test measurement system.It have already accorded with the request of the products basically.
