某型机载电子吊舱维护训练系统设计

Design of maintenance training system for an airborne electronic pod

针对某型机载电子吊舱维护训练成本高、组织难、周期长等问题,设计实现了一种基于半实物仿真的维护训练系统,该系统不仅在外观、连接和操作上与实装一致,同时在内部设计了信号仿真、故障设置、状态采集电路,通过采用通用I/O模块及RS 485总线主从方式构建远程测控体系,实现对电子装备工作状态的仿真。在此基础上设计内外场维护训练平台,能仿真内外场通电测试中对吊舱的操作控制,可灵活设置故障并真实再现故障现象,实现了对该型吊舱一二线技术保障训练的全过程仿真。实际应用表明,采用该系统实施吊舱维护训练能有效节约训练成本,降低训练风险,提高训练效果。

Since the maintenance training of a certain airborne electronic pod has high cost and long cycle,an airborne electronic pod maintenance training system based on semi-physical simulation was designed. The external form,connection and operation of the system are similar to actual equipment. The signal simulation,fault setting and state acquisition circuits were de-signed in the maintenance training system. The universal I/O modules and RS 485 bus were adopted to monitor and control these circuits. Based on this remote control structure,the maintenance training platform was established to realize the whole technical support training process simulation. It can simulate testing operations which are identical to actual operations of detection device. It can set typical faults,which are accordant with real faults. The practical application effects show that the system is feasible and efficient for the airborne pod maintenance training.
