Abstract

The invention relates to a universal screen door linkage control system suitable for various wireless transmission modes, belonging to the technical field of rail transit signal safety control. The invention aims to overcome the defect of single wireless technology in the existing screen door linkage control system and simultaneously satisfy the large scale development of the urban rail transit. The system comprises a vehicle-mounted control subsystem, a double-network redundant wireless communication subsystem, a ground control subsystem and a screen door control subsystem. The whole screen door linkage control system is organically integrated through various wireless transmission modes of the double-network redundant wireless communication subsystem, and opening / closing control of the screen door is completed according to the command of the vehicle-mounted control subsystem. Aiming at different environments such as underground tunnels, overheads and the like in the urban rail transit, the corresponding wireless transmission modes are adopted to complete efficient and reliable transmission of the relevant information of screen door control. The technical scheme has the following beneficial effects: the communication modes are flexible and varied; and the economic cost is saved.

Description

technical field [0001] The invention belongs to the technical field of rail transit signal safety control, and in particular relates to a universal screen door linkage control system applicable to various wireless transmission modes. Background technique [0002] At present, the screen door linkage control system in urban rail transit realizes the connection and isolation between the public area of ​​the station platform and the rail area by controlling the opening / closing operation of the screen door. When the train stops at the station and the parking position is within the allowable error range, the shielded door control system receives the on-board signal system linkage control command to complete the opening / closing operation of the shielded door. The traditional screen door linkage control system adopts a single information transmission method, which is greatly affected by the environment and has poor versatility. The environment of urban rail transit platforms is com...
