Design and Implementation of Testing and Diagnostic System for a Certain Head-Up Display Device

Head-up Display (HUD) is one of core devices of the air electron system for advanced campaign airplane, its performance is an important guideline for judging the campaign performance of airplane. In order to test the HUDs performance fully , diagnose and eliminate the HUDs faults effectively, the design and implementation of the testing and diagnostic system for a certain Head-Up Display (HUD) device is introduced. Based on the technology of fault converse inference , fuzzy nerve network and software adjusting itself etc, this system's reliability and flexibility is greatly enhanced. After being used, this system has lots of advantages, such as wide suitability , high automation and intelligence. It can test and diagnose the faults of the HUD device quickly and accurately, and it has a wide application foreground and good economic profit.
