| 摘 要： | 针对电路系统的特点,提出一种基于定性仿真和功能推理的故障诊断方法。在对电路系统进行简化与拆分的基础上,建立元件的定性仿真模型,对拆分后的电路系统进行定性仿真和推理,确定系统中功能执行元件的工作状态,并与实际的电路进行比较,从而将故障进行隔离定位。仿真实例说明了该方法的有效性。

| Abstract: | A method for fault diagnosis to the circuit is brought forward based on qualitative simulation and function reasoning.After the circuit system having been predigested and split,based on the simulation models,the states of the execute-components are confirmed through qualitative simulation.The fault can be isolated and located through comparing the simulation results with actual states of the components.The simulation result shows the effectiveness of the proposed method. |
