Problems solved by technology

Most of the existing technologies rely on the control interface of the ATP / ATO subsystem in the ATC system to complete the linkage control of the train door and the platform door, and cannot completely get rid of the interface with the signal system.
Another thing is that the reliability of the single wireless remote control system and method is not high, and it cannot be guaranteed that the train will not cause misoperation of the train door or the platform door within the non-stop precision range without causing the train door or the platform door to malfunction.

Embodiment Construction

[0029] Combine below figure 1 The train door and platform door linkage control system and linkage control method of the present invention are described as follows:

[0030] RFID radio frequency identification system:

[0031] Front-end RFID system, on-board RFID active tag 1, which integrates high-frequency 2.4GHZ transmission and low-frequency 120KHZ identification and positioning functions, and RFID reader 2 is installed on the side of the PSL operation box on the platform side facing the on-board tag; when the train enters the station and stops at the parking space After stabilization, the on-board tag is activated by the reader, and the tag sends a train arrival enabling signal with a high-frequency signal. The enabling signal recognizes the parking accuracy range of plus or minus 300mm. This enabling signal switch is connected in series with the hand / automatic signal in the headstock PSL controller 9, and when the headstock PSL mode of operation is automatic, this enabli...

Abstract

The invention provides a coordinated control system and method of a train door and a platform door. The coordinated control system comprises an RFID system, a ZigBee wireless two-way transmission system, a PSL platform door local control system and a PSA platform door state monitoring system; the RFID system provides an enabling switching signal of in-place stable stop of a train; the ZigBee wireless two-way transmission system completes wireless two-way transmission of instruction sending of the train door and the platform door and state feedback receiving of the platform door; the PSL platform door local control system completes data collection and transmission of the RFID system and ZigBee wireless two-way transmission system, and control over the platform door; the PSA platform door state monitoring system completes operation recording of all events, failure state alerting, and monitoring and control of on-line parameter adjustment. The coordinated control system and method of the train door and the platform door have the advantages that cost is low, the construction period is short, the interface integration level is high, higher reliability and safety are achieved, and operation is convenient.

Description

technical field [0001] The invention relates to automatic control, in particular to a train door and platform door linkage control system and a linkage control method. Background technique [0002] At present, the subway has become an important means of transportation for people to travel. With the accumulation of passenger flow during the peak period, passengers have put forward higher requirements for the operation efficiency of the subway. As far as the platform door system is concerned, the operation mode of the driver manually opening and closing the platform door and the station staff waving the flag to confirm the departure order has seriously affected the residence time of the subway on the platform and the departure time, so the train door and the platform door are synchronously and safely linked mode of operation is particularly important. However, for the existing old lines and newly-added electric railings or safety door platforms, the general method is to compl...
