Abstract: The weapon system has too many fault diagnosis systems and is invested too much in re-development. To solve those problems, the design of the platform is analyzed. The hardware of it consists of a control computer with PC104 structure and multi-type signal test interface boxes of equipments. The software of it synthesizes the methods of expert system, neural networks and signal process. The system model of the weapon system is abstracted. The particularity that there is no diagnosis interface and can not plug in or pull out the connectors frequently is proposed. A principle that it is better to diagnose without the direct connect and the order of fault diagnosis is from electrical control system to hydraulic system is summarized. The platform is used in practical equipment and a better effect is achieved.

摘要： 为了解决武器系统故障诊断系统繁多，重复开发和研制的经费投入过多等问题，提出了硬件采用PC104结构的主控计算机加各种型号装备的信号测试接口箱，软件综合采用专家系统、神经网络以及信号处理等故障诊断方法的平台研制方案。抽象了武器系统的系统模型，针对武器系统没有预留诊断接口、不能频繁地插拔连接器等特殊性，总结了尽量在与武器系统不发生物理连接的情况下定位故障以及故障排查的顺序是先电控系统后液压系统等平台建立的原则。该平台在实际装备上试用，取得了良好效果。
