【摘要】：基于建模的故障诊断方法直观、可重构、效率高,但当前主要对电气系统的信号/功能进行建模,难以准确地将故障定位到电气系统中具体的物理位置。针对上述问题,将逻辑物理综合模型扩展应用到通用电气系统故障诊断,提出电气系统的逻辑物理综合建模原理,给出层次化建模、可更换单元合并处理、信号反馈闭环通路及故障模式自动关联等建模处理策略,以三角波发生器电路为例,说明电气系统逻辑物理综合建模的实现过程。实例结果表明,该逻辑物理综合建模方法可以将诊断过程和结果直观地显示出来,适用于通用电气系统的故障诊断。
[Abstract]:The method of fault diagnosis based on modeling is intuitionistic, reconfigurable and efficient, but it is difficult to locate the fault accurately in the physical position of the electrical system because of the modeling of the signal / function of the electrical system. Aiming at the above problems, the logic physical synthesis model is extended to the fault diagnosis of general electric system, and the principle of logic and physical synthesis modeling of electric system is put forward. Based on the signal feedback closed-loop path and the automatic correlation of the fault mode, the realization process of the logic physical synthesis modeling of electrical system is illustrated by taking the triangular wave generator circuit as an example. The example shows that the method can show the diagnosis process and result intuitively, and it is suitable for the fault diagnosis of the general electric system.
