The interface structure and method between the high-speed rail disaster prevention and foreign object intrusion control system and the signal system

Abstract

The invention relates to the field of signal systems of high-speed rails, in particular to an interface structure between a disaster-preventing foreign matter invasion limiting system and a signal system of a high-speed rail and a method of the interface structure. The interface structure is characterized in that a set of acquisition lines are added to rear contacts of an uplink foreign matter invasion limiting relay and a downlink foreign matter invasion limiting relay and connected to an interface circuit board of a microcomputer monitoring system of a signal computer room; inspection relays, an uplink foreign matter invasion limiting relay front-contact alarm lamp and a downlink foreign matter invasion limiting relay front-contact alarm lamp are additionally arranged on the interface circuit board of the microcomputer monitoring system; a set of alarm circuit is formed by the contacts of the uplink inspection relay and the downlink inspection relay, the uplink foreign matter invasion limiting relay front-contact alarm lamp and the downlink foreign matter invasion limiting relay front-contact alarm lamp, and the circuit is used for comparing information acquired by the rear contacts of the uplink foreign matter invasion limiting relay and the downlink foreign matter invasion limiting relay with information sent by field monitoring points and giving an alarm. The interface structure between the disaster-preventing foreign matter invasion limiting system and the signal system of the high-speed rail and the method of the interface structure have the advantages that the problem of misinformation caused after the disaster-preventing foreign matter invasion limiting system of the high-speed rail is connected to an interface of a train control system is solved, the reason for faults can be judged out by electric service maintenance personnel by means of a microcomputer monitoring system analysis technique, and fault removal time is shortened.

Description

technical field [0001] The invention relates to the field of high-speed rail signal systems, in particular to the interface structure and method between the high-speed rail disaster prevention and foreign object invasion limiting system and the signal system. Background technique [0002] my country's high-speed railway disaster prevention and safety monitoring system is a project derived from the high-speed railway. Because it is not consistent with foreign standards, it cannot be referred to. The country is also in the initial stage of exploration, and there is no experience to learn from. The disaster prevention foreign object restriction subsystem needs to be linked with the signal system, and the disaster prevention equipment must have an interface with the signal device. During the interface process between the disaster prevention foreign object restriction system and the signal system, the signal system may be misconnected with the disaster prevention system informatio...

Problems solved by technology

[0009] The DC-24V power supply of the interface circuit board of the train control system → the drive unit of the uplink track circuit → the contact point (SGDJ) of the uplink track relay → the uplink information collection line → the cable from the train control system to the foreign object intrusion control combination cabinet → the foreign object intrusion limit combination in the signal room The front contact of the contact 1 of the downlink foreign matter invasion limit relay (XYWJ1) of the cabinet is disconnected from the middle contact, and the front contact of the uplink foreign matter invasion limit relay (SYWJ1) contact 1 is disconnected from the middle contact. The contacts are in bad contact, and the DC +24V power supply of the interface circuit board of the train control system cannot be supplied to the drive unit of the up track circuit, causing the drive unit of the up track circuit to lose power, reducing the reliability of the original interlocking system and generating false alarms, triggering the train control system, Cause the train control system to send instructions to the microcomputer interlocking system to make the section protection signal machine of the foreign object intrusion display a prohibition signal, and the section displays a red light band (indicating that the section is occupied), and the train is prohibited from entering the section, which will Unnecessary impact on rail transport
