A screen door control device and control method with the function of preventing accidental movement

Abstract

The invention discloses a shielding door control device and method with the accidental movement preventing function. The device comprises a plurality of door control units and a central control disc respectively connected with the door control units. Each door control unit correspondingly drives and controls a unit door of one shielding door through a driving module, the output end of the driving module in each door control unit is further provided with a driving output control module for controlling the driving output, each driving module is connected with a direct current motor for controlling the corresponding unit door through the corresponding driving output control module, and the central control disc sends control instructions to the driving modules and the driving output control modules in the door control units to control the unit doors to move. The method includes the steps that when the shielding doors need to be controlled to be opened or closed, the driving modules and the driving output control modules are respectively controlled through the central control disc to control the shielding doors to move. The shielding door control device and method have the advantages that the structure is simple, the shielding-door accidental movement preventing function is achieved, and the safe performance is high.

Description

technical field [0001] The invention relates to the technical field of urban rail transit, in particular to a screen door control device and control method suitable for urban rail transit with the function of preventing accidental movement. Background technique [0002] There are subway and other rail transit construction projects in many cities across the country. The screen door system is installed on the edge of the station platform along the urban rail transit to provide a controllable passage between the public area of ​​the platform and the rail train. The screen door system is equipped with sliding doors, emergency doors, and end doors on the platform. When the train enters the station, the sliding doors are opened or closed in conjunction with the movement of the train doors to provide passengers with access to the train. The use of the screen door system separates the public area on the platform side from the space on the track side, avoiding the safety hazards of p...

AI Technical Summary

Problems solved by technology

The above-mentioned operation of the screen door is independently controlled by the drive circuit. If the action command received by the drive circuit is disturbed or the drive circuit is abnormal, resulting in a wrong recognition of the action command, it will lead to misoperation and cause the screen door to move unexpectedly, seriously affecting the operation of the vehicle and Safety of platform waiting personnel
