Petri网是分析系统运行规律的有效工具。 Petri网过程可以反映系统故障传播的特征。提出了Petri网故障检测过程的构建和定义方法，分析了Petri网过程中的故障性能特征。基于上述研究基础，提出了一种基于Petri网过程的故障检测与定位方法。首先，给出了用于故障检测的具有输入和输出的Petri网模型。然后详细描述了利用该模型进行故障检测和定位的方法。最后给出时序电路故障检测实例，验证了该方法的正确性。
Petri net is an effective tool to analyze the operating rules of the system. Petri net process can reflect the feature of the system fault propagation. Construction and definition method of Petri net fault detection process is presented and the fault performance features in the Petri net process are analyzed. Based on the above research foundation, a method of fault detection and location with Petri net process is presented. Firstly, Petri net model with input and output for fault detection is given. Then fault detection and location method with this model is described in detail. Finally, an example of fault detection in sequential circuit is given to verify the correctness of the method.
