Research on Problem of Occasional False Alarms in a Certain Communication Navigation Recognition Subsystem
The communication navigation recognition subsystem has complex functions.The faults occur frequently during the ground power commissioning and flight of the aircraft.By analyzing the faults,the quality control of the product can be strengthened,and the technical status,reliability and maintainability of the product can be improved.The problem caused by virtual alarm of a certain band antenna interface module of the subsystem during a certain task execution period was analyzed and investigated.The cause of the problem was found and the corrective measures and summarizes were made.A sample for staring and continuing the troubleshooting of similar systems was provided.The product quality technical atatus and production troubleshooting efficiency were improved.
