Abstract:

Based on the analysis of the demand of virtual maintenance training and failure mechanism, the method based on multi-signal modeling for electronic equipment is put forward. The paper researches the problems of fault data generation and real-time detection, simulation of fault phenomena and flow of simulation running model in virtual environment. Virtual instrument developed in the environment of VC++ is used to get the test signal of virtual prototyping with the real-time communication module. Finally, a certain type of UAV command and control system fault modeling and simulation is achieved in Virtools, which verifies the feasibility of the method. The multi-signal model can describe the track of fault transfer completely and construct fault mechanism model efficiently and flexibly. It provides a favorable maintenance environment for implementation of logic diagnosis. 
