Description

Technical Field

[0001] The present invention relates to a station platform door control system, which is applicable to subway screen doors, subway half-height safety doors, urban rail platform door systems, and BRT platform door systems. Specifically, it is an infrared wireless-based vehicle door and platform door control device and method. Background Art

[0002] Currently, the interface between the platform door and the signal system is divided into two parts: Ethernet and safety relay double-cut hard wire.

[0003] The Ethernet interface is responsible for transmitting the door-platform door alignment isolation information. The current information transmission is "vehicle control system" - "signal system" - "platform door central control panel 8" - "door control unit 9". The information transmission involves multiple changes in the transmission mode.

[0004] The double-cut hard wire of the safety relay contains information such as "door opening command", "door closing command", "close locking" and "interlock release". In some cases, the platform door system equipment and the interlocking system equipment are far apart, and long-distance thick cables need to be laid. Long-distance cables increase the uncertainty of information transmission. Summary of the invention
