Method and device for preventing subway train from running after objects are clamped between door of subway train and platform screen door

Abstract

The invention provides a method and a device for preventing a subway train from running after objects are clamped between a door of the subway train and a platform screen door, and belongs to the field of emergency safety devices. A door barrier-free automatic detecting interlocking condition and a corresponding automatic detecting device are added on the basis of the train starting safety interlocking conditions for the conventional rail vehicle control system, and are used for detecting whether objects which block light are clamped between two train doors after a train door 'closing' action is finished, a rail transit vehicle is prevented from starting and running after the objects are clamped between a door of the rail transit vehicle and the platform screen door, operation load of a driver can be reduced, the driver can concentrate on driving safely, and injury to passengers due to a 'door rushing' phenomenon can be prevented, station staff can timely and rapidly find out positions of 'door rushing' passengers or the clamped objects, faults can be removed in time, the safety of a whole rail traffic system can be improved, influences due to human factors are reduced, the stay time of the rail transit vehicle at each station can also be shortened, and the operation efficiency of the rail vehicle is improved.

Description

technical field [0001] The invention belongs to the field of emergency safety devices, in particular to a safety monitoring device for rail transit vehicles. Background technique [0002] With the rapid development of urban transportation construction, underground or above-ground rail transportation methods are increasingly used. [0003] In the current rail transit stations, in order to prevent passengers on the platform from being squeezed off the platform or falling into the gap between the platform and the rail transit vehicle compartment due to crowding, various guardrails or screen doors are usually installed. device. The common feature of these protective devices is that, on the positions opposite to the doors of rail transit carriages, movable doors that can move laterally are respectively correspondingly arranged, and warning lights and buzzers are usually arranged above the screen doors or on the guardrails. The dodge door is closed. When the rail transit vehicle...

Problems solved by technology

[0012] Objectively speaking, although the above supplementary measures are helpful to prevent the recurrence of such incidents, they rely too much on human factors such as the driver's sense of responsibility and personal quality, and are likely to affect the driver's driving operation energy and distract him. best choice

[0013] In addition, due to the existence of the screen doors, the platform staff cannot quickly find the location of the passengers who "rush the door" or the trapped objects. They can only search for the screen doors one by one, which is not convenient to rescue the trapped passengers and solve the problem in time.
