The invention provides a relay circuit diagnosis method and system, which are used in the field of relay circuit fault detection and diagnosis. The relay circuit diagnosis method comprises the steps of receiving a preset logic relationship of a relay circuit, collecting actual operation state information of the relay circuit, obtaining the actual logic relationship according to the actual operation state information, comparing the actual logic relationship with the preset logic relationship, and performing fault judgment according to a comparison result. According to the diagnosis method and device of the relay circuit, the specific fault position can be accurately positioned, and the accuracy of fault diagnosis of the relay circuit is improved.

    本发明提供的一种继电电路诊断方法及系统,用于检测继电电路故障诊断领域。继电电路诊断方法包括:接收继电电路的预设逻辑关系,采集继电电路的实际运行状态信息,根据该实际的运行状态信息得到实际逻辑关系,对比实际逻辑关系和预设逻辑关系,根据对比的结果进行故障判断。根据该继电电路的诊断方法及装置,可以准确的定位具体的故障位置,提高继电电路故障诊断的准确性。
