基于仿真模型的话音电台故障诊断方法
|
摘要
针对复现困难且缺乏测试数据和先验知识的电子通信设备故障,提出一种基于仿真模型的故障诊断方法。首先,建立故障系统的仿真模型,并尽可能精简该模型;然后利用该模型,对假设的故障原因逐一模拟,同时观察各个关键节点的输出;最后找出与已有测试数据最符合或最相近的结果,并完善仿真模型。在此基础上分析故障产生机理,完成故障诊断工作。该方法是一种正向逻辑推理法,与故障树分析法相反,可作为故障树分析法的补充手段,并在某话音电台的故障诊断过程中发挥了重要作用。
Aiming at the fault of electronic communication equipment, which is difficult to reproduce and lacks test data and prior knowledge, a fault diagnosis method based on simulation model is proposed. First, the simulation model of the fault system is established, and the model is simplified as far as possible. Then the model is used to simulate the hypothetical fault causes one by one, and to observe the output of each key node at the same time. Finally, find the most consistent or similar results with the existing test data, and improve the simulation model. On this basis, the failure mechanism is analyzed, and the fault diagnosis is completed. This method can be used as a supplementary means of fault tree analysis which is a forward logic reasoning method and is opposite to the fault tree analysis method, and plays an important role in the fault diagnosis of a voice radio.
