Research And Design Based On Electrical Machinery Pilot System Of Lab VIEW
Abstract :This subject is research and design based on electrical machinery pilot system of LABVIEW, among them involve the slogan that "The software is an instrument " that U.S.A. NI Company advocated. The fictitious instrument is a brand-new subject. The traditional electronic measuring instrument, because its function is single , bulky, already it is very difficult to meet demands of real work and has compared with traditional instrument been shown as: With better function, processing speeds quick, frequency band wide, use wide, operate simple, volume little, expandability better. The popularization degree and performance of the microcomputer are improving constantly, make the system of fictitious instrument based on PC platform arise at the historic moment. This text has described the signal based on concept of the fictitious instrument and gathered the systematic realization scheme. Use the data collecting card of independent development, has realized because of PC platform finally, the figure with cymometer and analysis instrument function of frequency spectrum stores the oscillograph system. Because has used Lab VIEW to carry on systematic software development , has made this system have very good commonability and flexibility . This text software discuss data transmission, show and method that punish and realize the key technology of the course while the signal gathers mainly, guide and carry on programming according to the experiment at the same time, transfer every kind of sub VI , the purpose of the implementation system. Because this subject hardware adopts the fictitious instrument, only need the regular sensor , the core of the hardware is establishment and control of the frequency converter which controls the electrical machinery. This subject has greater potentiality, because can utilize simulation of PCI to export and automatically control the frequency converter , realize the design of the automatic data collecting system.
