Intelligent train door redundancy control system and method based on redundancy technology

Abstract

The invention discloses an intelligent train door redundancy control system and method based on a redundancy technology. On the basis of an existing first train door control unit and second train doorcontrol unit, a redundancy train door control unit is further arranged, and once the redundancy train door control unit detects that the first train door control unit and / or the second train door control unit connected with the redundancy train door control unit breaks down, the redundancy train door control unit automatically conducts take-over control on the first train door control unit and / orthe second train door control unit which breaks down. Normal door opening and door closing of a train door can be guaranteed, and thus the reliability and efficiency of train operation are improved;and in addition, the redundancy train door control unit simultaneously monitors safety-related functions, input instructions and response results are compared (for example, if the door opening condition is not met, the train door moves in the door opening direction), abnormal actions are prevented, abnormal door opening under unexpected situations is prevented, and thus safety is improved.

Description

technical field [0001] The invention specifically relates to an intelligent vehicle door redundancy control system and method based on redundancy technology. Background technique [0002] The urban rail vehicle door system is a highly integrated system of electromechanical technology, software and hardware technology, which is a typical safety-related system. The Electric Door Control Unit (EDCU) is the key core component of the door system. On existing urban rail vehicles, each door system is only equipped with a fully functional EDCU, and each EDCU only controls the opening and closing of one door system, and reports the relevant information of the current door system (door status, fault information, etc.) to the Train Control and Management System (Train Control Management System, TCMS). Although some doors also have remote isolation devices, they only close and isolate the doors in the event of a failure, which cannot guarantee the subsequent normal operation of the veh...

Problems solved by technology

Although some doors also have remote isolation devices, they only close and isolate the doors in the event of a failure, which cannot guarantee the subsequent normal operation of the vehicle

[0003] For the existing door system, once an EDCU fails, the corresponding door will not be able to open and close, requiring the driver or crew to manually isolate the door, and the door will be out of service, which will seriously affect the reliability and efficiency of vehicle operation; Although the door of the isolation device does not require manual participation in the isolation, the door will be out of service, so it cannot guarantee the normal operation of the vehicle. When an emergency occurs, the door cannot be opened, and passengers cannot escape quickly and effectively, posing a greater safety hazard
