Description

Technical Field

[0001] This utility model relates to a station platform door control system, applicable to subway platform screen doors, subway half-height safety doors, urban rail platform door systems, and BRT platform door systems. More precisely, it is an infrared wireless-based door and platform door control device. Background Technology

[0002] Currently, the interface between the platform screen doors and the signaling system consists of two parts: Ethernet and dual-cut hardwired safety relays.

[0003] The Ethernet interface is responsible for transmitting alignment and isolation information between the train door and the platform screen door. Currently, the information transmission route is: "Train Control System" — "Signal System" — "Platform Screen Door Central Control Panel 8" — "Door Control Unit 9". This information transmission involves multiple changes in transmission methods.

[0004] The double-switch hardwired safety relay contains information such as "door opening command," "door closing command," "locking," and "interlock release." In some cases, the platform screen door system equipment and the interlocking system equipment are far apart, requiring the laying of long-distance, thick cables. Long-distance cables increase the uncertainty of information transmission. Utility Model Content

[0005] The purpose of this invention is to provide an infrared wireless control device for vehicle doors and platform screen doors, so as to change the current information transmission method, improve information transmission efficiency, and reduce construction costs.

[0006] The technical solution of this utility model relates to an infrared wireless vehicle door and platform door control device, characterized by comprising: a local control panel, a central control panel, a door control unit, an infrared ground control module, and an infrared vehicle control module; the central control panel is located in an equipment room; the local control panel is located at both ends of one side of the platform; the door control unit is located in the top box or side box of a single door unit; the infrared ground control module is located on the track side of the door unit; the infrared vehicle control module is located on the side or top of the vehicle door; wherein, the infrared vehicle control module and the infrared ground control module are installed in a position that ensures they are facing each other after the vehicle has come to a complete stop; the central control panel and the local control panel are electrically connected via a first communication interface, which is an internal relay contact interface; the central control panel and the emergency control panel are electrically connected via a second communication interface; the central control panel and the door control unit are electrically connected via a third communication interface; the door control unit and the infrared ground control module are electrically connected via a fourth communication interface; the infrared vehicle control module and the infrared ground control module are electrically connected via a fifth communication interface; and the infrared vehicle control module and the vehicle control system are electrically connected via a sixth communication interface.

[0007] The first communication interface is a relay contact interface.

[0008] The second communication interface is a relay contact interface.

[0009] The third communication interface is a hardwired interface.

[0010] The fourth communication interface is a serial bus interface.

[0011] The fifth communication interface is an infrared wireless communication interface.

[0012] The sixth communication interface is an Ethernet / bus communication interface.

[0013] The individual vehicle door and the individual platform door communicate in a one-to-one correspondence, and pairing and control information transmission are achieved through paired wireless communication.

[0014] The advantages of this invention are: the vehicle-controlled door opening information is sent directly from the vehicle to the platform door system, eliminating the need for long-distance and complex communication and communication mode conversion between the vehicle control system and the signal system, and between the signal system and the platform door system, thus saving on power cable consumption and reducing construction costs.

[0015] The optimization of positional isolation information into point-to-point information transmission saves intermediate steps such as information integration, conversion of multiple communication methods, and information packet distribution, thereby improving information transmission efficiency.

The infrared ground control module 10 forwards the commands to the door control unit 9 through the fourth communication interface. The door control unit 9, in conjunction with the platform-level door opening / closing commands received through the third communication interface 3, performs priority processing and then drives the circuit to complete the door opening / closing control.
