本文提出了面向性能的故障诊断方法。测后模拟一般都是从基本电路理论开始推导,从测试已知量求解故障位置或故障元件值。但一般从可及节点得到的测量值只是有效值,而不是基本电路理论中所要求的带相位的电量。诊断是为了维修,而维修是为了恢复仪器的性能。文中提出了直接面向性能的诊断与维修方法。先由检测量求解幅频特性,再由幅频特性求解元件值,以定位故障元件。
This paper presents a performance-oriented fault diagnosis method. After the test simulation is generally derived from the basic circuit theory, known from the test solution to the location of the fault location or fault component value. However, the measured values obtained from reachable nodes are only valid values, not the phase-laden quantities required in basic circuit theory. Diagnosis is for maintenance, and maintenance is to restore the performance of the instrument. The paper presents a direct-oriented performance of the diagnosis and repair methods. The first detection of the amount of frequency response characteristics, and then by the amplitude-frequency characteristics of component values to locate faulty components.
