Abstract

A control system of a subway platform shielded gate comprises a selector switch arranged on a platform local control plate, a selector switch arranged on a comprehensive backup plate and a shielded gate unit controller. The shielded gate unit controller comprises a safety relay control module and an electronic control module. The safety relay control module sends a hard wire instruction to a gating unit when operates normally. The selector switch arranged on the platform local control plate or the selector switch arranged on the comprehensive backup plate is switched over to enable the electronic control module to send the hard wire instruction to the gating unit when the safety relay control module operates abnormally. Due to the fact that the relay control module (RM) cannot output an effective instruction, the electronic control module (EM) sends a control instruction to a digital counting unit (DCU), and a situation that the shielded gate on the whole side cannot work normally when relay faults occur is avoided.

Description

technical field [0001] The invention designs a subway platform screen door system, in particular a control system for a subway platform screen door. Background technique [0002] The subway platform screen door (usually also called the platform safety door) is set along the edge of the subway platform, which can isolate the train from the waiting room of the subway platform. [0003] In the current subway shielded door system, only the logic control unit composed of safety relay group is used to control the switch of the whole side shielded door. Due to the limitation of the service life of the relay, or when the relay fails, the logic control unit cannot issue a door opening and closing command to the screen door, which will seriously affect the operation of the subway and cause adverse effects. Contents of the invention [0004] The object of the present invention is to provide a control system for a subway screen door, which is used to solve the technical problem that ...
