The Design of Measurement System of Aircraft Electrical Power Parameters Based on Virtual Instruments

This paper introduces the realization of data acquisition and processing system based on PXI module. This system uses hardware modules based on PXI Bus and Labview graphic program language to design the various arithmetic of aircraft electrical power parameters and implements the mutil channel data acquisition and high performance parallel data acquisition. By using the virtual instrument font panel, the GUI is very clear and simple to be operated. Experiment in some type aircraft electrical power supply system shows that the system has good and reliable performance for the measurement of steady and transient parameters. This system has prospects for extensive application to other measurements.
