The invention discloses a monitoring system for tramcar platform doors. The monitoring system includes a first vehicle-mounted remote controller, a second vehicle-mounted remote controller, a platform signal receiving device, an uplink tramcar detecting device, an downlink tramcar detecting device, an uplink logic unit controller, a downlink logic unit controller, a control panel, a monitoring host, uplink door machine controllers and downlink door machine controllers; the monitoring host monitors the states of the door machine controllers through two CAN communication buses; the uplink tramcar detecting device and the downlink tramcar detecting device are connected with the control panel respectively through the uplink logic unit controller and the downlink logic unit controller; the control panel is connected with the monitoring host; the platform signal receiving device is connected with the uplink logic unit controller and the downlink logic unit controller; the uplink logic unit controller and the downlink logic unit controller are directly connected with the monitoring host; and the uplink logic unit controller and the downlink logic unit controller are used for controlling door opening and closing actions of the door machine controllers. The real-time performance and reliability of the monitoring system can be ensured. The monitoring system can assist in preventing wrong control, and is safe and the reliable, and has a bright application prospect.
Description
technical field [0001] The invention relates to the technical field of rail transit doors, in particular to a monitoring system for tram platform doors. Background technique [0002] The door system of the tram platform is a barrier between people and the tram. Whether all the equipment of the door system works normally is directly related to the personal safety of the passengers on the platform. The monitoring of the door system must be real-time and reliable. Currently, there are The monitoring system of the tram station platform door system mostly uses the RS485 communication bus to realize the single door monitoring of a single platform, and the control system of the door system realizes the wireless control door opening and closing function through radio frequency or infrared remote control. [0003] However, the way of RS485 communication bus can only be carried out in the way of polling by the master station, and the real-time performance and reliability of monitoring...
