军用车辆电气系统典型故障诊断方法的研究

Research on Diagnosis Method of the Military Vehicle Electricity System Typical Fault

通过对电气系统常见的传感器类故障、电机类感性绕组的故障、输配电线路故障和数字控制部件故障的分析,提出了相应的基于恒流源的故障诊断方法、基于脉冲序列的故障诊断方法、基于状态信息(电压/电流等)的故障诊断方法和基于BIT的故障诊断方法.针对上述方法,采用Matlab软件进行了仿真,结果表明:提出的4种故障诊断方法能够对相应的典型故障进行合理有效的诊断,为应用新技术推进电气系统故障诊断技术研究提供了一种实现方法.

Through the analysis of the common electrical system faults imcluding sensor fault, motor perceptual winding fault, power transmission and distribution line fault and digital control unit, a series of fault diagnosis methods was proposed based on the constant current, the pulse sequence, the state information and the BIT in this paper. To evaluate these methods, the Matlab software is employed to simualte the diagnose, the results show that the proposed four kinds of fault diagnosis methods are able to produce reasonable and effective to the corresponding typical fault diagnosis, wahic demonstrates a novel applicable method for the application in fault diagnosis of the electrical system.
