Petri网技术在火控系统故障诊断中的应用

Application of Petri Network Technology in Fire Control System Fault Diagnosis

以Petri网技术为工具，分析了火控系统的故障特点，建立了系统Petri网故障诊断模型，提出了系统故障诊断层次的Petri网表示方法和故障混合Petri网模型建立的新方法。HPSim仿真表明：该新方法比故障树等传统的方法具有方法简单、形象直观、建模简单等优点，并且该方法能方便地进行知识的表式、逻辑表达，对具有网络拓扑结构的分析尤为有效。

In this paper, by using Petri Net technology and analyzing the complex fire control system, the Petri Net model of system of fault diagnosis is built. The new way of Petri Net fault diagnosis expression and model of mixed fault is put forward. In addition, the new way as compared with traditional way, is simple and directly observable by HPSim simulink software. In particular, the new way is more effective in knowledge expression,logic convection, analysis of system with net topology construction .
