Testing Electrical Parameter SRD Based On Virtual Instrument

With the continuous development of modem science technology and economy, various measure and test instruments are required to accomplish more and more complicated jobs in measuring, monitoring and automatic manufacturing. And the demand for measure technology by test equipment is getting higher. As a result,the test cost increases by a wide margin. In recent years, a new measure technology that combines the technologies of electronic, technologies of computer, technologies of network, is developed and this new technology is named VI.This thesis examines the characteristics and problems of the present Switched Reluctance Motor inspecting and testing system, points out the inevitable appearance of Virtual Instrument. And explains the concept of VI, its hardware and software structure, its characters and applications, It develops a system based on the multi-function data adapt card and the graphic programming language - LabVIEW. The principle of this system is: Use DAQ cardto acquire physical analog and digital data coming from couples of sensors, appropriately process the data, then transmit it to computer by PCIBUS, the software of system will deal with the data. By this researches of VI it proved that this way of measuring is converient .reliable and effective.
