摘要
从故障诊断的角度对光驱电路板原理图进行分析,建立了光驱电路板的诊断信息流模型,模型反映了试验间及试验与故障之间的观察关系。基于该模型讨论了光驱电路板的故障诊断问题,实例说明了模型的有效性。
The schematic diagram of CD-ROM driver's PCB (Printed Circuit Board) is analyzed from the angle of fault diagnosis, and the diagnostic information flow model of CD-ROM driver's PCB is built. The observing relations among tests and relations between the faults and tests are emphasized and described clearly in this model. Based on this model, fault diagnosis of CD-ROM driver's PCB is studied, and efficiency of the model is verified.
