Train door and platform door fault alignment isolation system and method for full-automatic driving train

Abstract

The invention discloses a fault alignment isolation system and method for a train door and a platform door of a full-automatic driving train, and aims to overcome the defects existing in linkage of the train door and the platform door in traditional CBTC (Communication Based Train Control), when the train door breaks down, a PSD does not open the platform door aligned with the faulty train door, and when the platform door breaks down, the TCMS does not open the train door aligned with the faulty platform door. Therefor, when one of the train door and the platform door breaks down, the other one is in linkage isolation, automatic alignment isolation judgment of the faulty door is achieved in advance, the faulty platform door or the train door is bypassed, the fault isolation state is visually displayed in real time, vehicle-mounted broadcasting and station broadcasting are linked, and system linkage failure is avoided. Low efficiency caused by manual bypass is replaced, the running efficiency of a train system is improved, and the riding safety of passengers is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of automation, and in particular relates to a fault alignment and isolation technology for car doors and platform doors. Background technique [0002] With the development of urban rail transit, subway platform doors have been widely used. In the traditional communication-based train automatic control system CBTC, the linkage control between the train door and the platform door has been realized after the train enters the platform and stops, that is, the signal system automatically opens the train door. At the same time, the platform door is controlled to open, and the train door is automatically closed, and the platform door is closed in linkage. [0003] In the traditional CBTC, the linkage between the train door and the platform door is realized through interlocking and forwarding. After the train enters the station and stops, the on-board control unit OBCU first judges whether the door opening condition ...

AI Technical Summary

Problems solved by technology

[0004] Traditional CBTC provides manual bypass function for drivers and platform staff. When one of the train door or platform door fails, the faulty door and the faulty platform door will be manually bypassed, and the system will no longer automatically realize the linkage control of the train door and platform door.

[0005] With the existing processing mechanism, when one of the train doors or platform doors fails, if manual bypass is not performed, the linkage operation will fail and there will be safety hazards. When multiple train doors or platform doors fail in the line, manual bypass is inefficient , especially on lines with very short intervals of vehicle operation, it will cause major problems such as delays, and it will also delay the travel time and affect the efficiency of train operation
