指挥控制系统智能故障诊断技术研究

为有效提高指控装备故障诊断效率,将故障树分析法引入到故障检测专家系统的推理机制中,把指控装备中复杂的诊断分解为多个相对独立的故障树,建立基于故障树的专家系统诊断模型。通过对被测对象信号描述及适配器描述工具和诊断流程输入工具的开发,可快速完成对被测对象的需求信号和故障树的配置。通过仿真表明,该方法诊断效率高,能够快速地定位故障单元,准确率高,具有较高的实用性。

Study on intelligent diagnosing technology for C3I system

In order to improve the efficiency of diagnosis,fault tree is introduced into the expert system.The diagnosing course of C3I system is divided into separate fault trees,and the expert system model is established according to the fault trees.Configuration of signals and fault trees can be quickly finished by building tools for detecting signals,adapter describing and diagnosing course inputting.Simulation results indicate that this method is fast,accurate and efficient.
