Abstract

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.

Description

technical field [0001] The present application relates to the field of circuit fault diagnosis, in particular to a relay circuit fault diagnosis. Background technique [0002] Relay circuit, also known as relay-contact circuit, is a circuit mainly composed of relay contacts and coils, electric construction and buttons, etc. This kind of circuit is generally more complicated, and it is usually used in automatic protection, safety protection, and conversion circuits. use. [0003] For some large-scale control circuits, more relays will be used to build the circuit, and the construction of the circuit is generally realized manually, and it is likely that there will be construction errors that the construction personnel have not discovered. In addition, the relay circuit may also fail during use. The existing fault diagnosis of the relay circuit is based on the input and output of the relay circuit. It is necessary to accurately find out the specific fault of the relay circuit...
