System and method for controlling urban rail transit platform gap automatic compensation mechanism

Abstract

The invention discloses a system and method for controlling an urban rail transit platform gap automatic compensation mechanism. The system comprises a turnover pedal, a turnover mechanism, a turnover motor, a turnover motor controller, an expansion-in-place detecting switch, a door controller and an upper computer, wherein the turnover pedal is mounted on the external side of a safety door threshold through the turnover mechanism; the turnover motor is positioned on one side of the turnover mechanism to control the turnover of the turnover mechanism so as to expand or retract the turnover pedal; the expansion-in-place detecting switch is positioned on the other side of the turnover mechanism; the turnover motor is connected with the turnover motor controller; the expansion-in-place detecting switch is connected with the door controller; and the turnover motor controller and the door controller are connected with the upper computer, respectively. According to the invention, as a platform gap compensator and a safety door are linked with each other, passengers are prevented from missing steps or dropping small articles to rails and the problem that the vehicle body may be scratched by a fixed platform gap compensator is solved; and the system and method for controlling the urban rail transit platform gap automatic compensation mechanism, disclosed by the invention, has the advantages of safety, reliability, convenience in use and good application prospect.

Description

Technical field [0001] The invention relates to a control system and method for an automatic compensation mechanism of urban rail transit platform gaps, and belongs to the technical field of rail transit. Background technique [0002] In recent years, with the rapid development of the urban rail transit industry, people's requirements for the safety and comfort of urban rail transit operations have increased day by day, and the safety performance of urban rail transit safety doors has received more and more attention. At this stage, almost all new urban rail transit lines are equipped with rail transit safety doors. At the same time, the old lines in some cities have also started to install and renovate projects. [0003] The installation of safety doors on rail transit platforms can better ensure the safety of passengers waiting on the platforms, reduce station staff, reduce operating costs, and comprehensively solve new issues encountered in the development of intercity rail tra...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to overcome the existing fixed platform compensator to compensate the gap between the platform and the car body of the urban rail train, which often rubs against the car body during the operation of the train, and can only fill a small part of the gap. Gap, can not fundamentally solve the problem of gap

Compared with the prior art, the urban rail transit platform gap automatic compensation mechanism control system and method provided by the present invention enable the platform gap compensator to be linked with the safety door, which not only prevents passengers from stepping into the air or small objects fall to the track, but also It solves the problem that the fixed platform gap compensator will scratch the car body, is safe, reliable, easy to use, and has a good application prospect
