Abstract

The invention discloses a fault monitoring method for an interface circuit between an anti-flooding door and a signal system, comprising: collecting the interface circuit between the anti-flooding door and the signal system in real time, collecting key voltage information and relay state information of the interface circuit; The state information and the key voltage information of the interface circuit are analyzed in real time to obtain the alarm signal of the interface circuit; according to the alarm signal, the fault location of the anti-flood door and the signal interface circuit is located, and the fault monitoring of the anti-flood door is completed. This invention solves the problems of low efficiency and heavy workload in the traditional monitoring of the state of the anti-flood door and the signal interface, collects the interface voltage information, and collects the status of the relay and the interface voltage information for intelligent analysis, accurate alarm, and facilitates the interface between the anti-flood door and the signal The real-time monitoring of the status makes the monitoring more perfect and intuitive, and improves the timeliness, safety and accuracy of the monitoring.

Description

technical field [0001] The invention relates to the technical field of urban rail transit, in particular to a fault monitoring method for an interface circuit of an anti-flood door and a signal system. Background technique [0002] The anti-flood door equipment is a unique kind of airtight equipment in the subway system to prevent floods from flooding into the station and section tunnels. If a geological disaster occurs and the river water is poured into the subway tunnel, emergency partition measures can be taken for the anti-flood door equipment to avoid injury to personnel and related equipment. [0003] In urban rail transit, the signal system to protect the safety of subway trains must realize safe and efficient linkage control with the flood-proof door system. If the interface between the flood-proof door and the signal system fails, it will directly affect the safety of the train. With the rapid development of urban rail transit, the operating shifts are becoming mo...
