Design of Power Simulation Platform System Based on Virtual Instrument

In order to provide simulation environment for data control unit of avionics system and fulfill the demand of avionics system test,power simulation platform system which is based on virtual instrument is designed.By PXI technology and LabVIEW platform,the system is able to simulate discrete signal,analog signal and data bus communication.According to on-spot debug result,power simulation platform system can replace the former system which is imported and makes it possible to further improvement and upgrade the system.
