摘　　要：某型军用雷达为复杂电子设备,其在服役部队的时间逐年增加,使用过程中的故障明显增多,由于基层级维修能力较弱,雷达的维修保障基本依靠工厂支援,及时性和有效性都不能满足部队需要,严重制约雷达分队战斗力的形成。为了解决雷达在基层部队使用中维修困难的问题,提高雷达的综合保障能力,研制了一种便携式故障诊断系统。该系统由信号采集板、嵌入式主板、电源管理模块、人机交互模块等组成,采用神经网络技术,实现了故障的快速诊断。解决了雷达现有维修设备体积庞大、配套设备复杂、价格昂贵、操控复杂等问题。实验结果表明,系统实现了故障诊断平台的小型化和智能化,具有较高的故障诊断效率,可快速提高雷达的维修保障能力。One type of military radar is a complex electronic equipment, the service time of a certain type of military radar has increased year by year, and the faults in the use process have increased significantly. Due to the weak maintenance capability at the grass-roots level, the maintenance support of the radar basically depends on factory support, and the timeliness and effectiveness can’t meet the needs of the army, which seriously restricts the formation of the combat effectiveness of the radar unit. In order to solve the problem of difficult maintenance of radar in grass-roots units and improve the comprehensive support ability of radar, a portable fault diagnosis system is developed. The system is composed of signal acquisition board, embedded motherboard, power management module and human-computer interaction module. Neural network technology is used to realize rapid fault diagnosis. It solves the problems of the existing radar maintenance equipment, such as huge volume, complex supporting equipment, high price, complex operation and so on. The experimental results show that the system realizes the miniaturization and intellectualization of fault diagnosis platform, has high fault diagnosis efficiency, and can quickly improve the maintenance and support ability of radar.
