The invention discloses a redundancy control system of a train shield gate. The redundancy control system of the train shield gate comprises a vehicle-mounted device, a first vehicle-mounted radio frequency unit, a shield gate vehicle-mounted radio frequency unit, a movable closing control device, a fixed closing control device, an input and output control device and a shield gate control relay, wherein the first vehicle-mounted radio frequency unit and the shield gate vehicle-mounted radio frequency unit are connected with the vehicle-mounted device, the movable closing control device is connected with the first vehicle-mounted radio frequency unit through a movable closing access link in a wireless mode, and the fixed closing control device is connected with the shield gate vehicle-mounted radio frequency unit through a shield gate access link in a wireless mode. The invention further discloses a control method. The control method comprises the following steps that the vehicle-mounted device detects whether communication with the movable closing control device is normal, if yes, the vehicle-mounted device sends an instruction to the movable closing control device, and if not, the vehicle-mounted device detects whether communication with the fixed closing control device is normal. If the communication with the fixed closing control device is normal, the vehicle-mounted device sends an instruction to the fixed closing control device, and if the communication with the fixed closing control device is abnormal, the vehicle-mounted device detects a communication link and restarts the whole control process. The redundancy control system and method of the train shield gate guarantee the safety of the shield gate and open and close the shield gate in time, thereby guaranteeing smooth operation of a train.
Description
technical field [0001] The invention relates to the field of subway signal systems, in particular to a redundant control system and control method for train screen doors. Background technique [0002] At present, subway trains are generally driven automatically in a mobile blocking manner, and the train doors are automatically opened after arriving at the station. At the same time, the screen door next to the track should open automatically. The train is controlled by the on-board equipment, and the screen door is controlled by the mobile authorization device next to the track. Under normal circumstances, the communication between the on-board device and the mobile authorization device is normal. When the train door is opened, the screen door will also open at the same time. If the screen door cannot be opened in time or closed on time when the communication is abnormal, it will affect the operation of the train and easily cause safety accidents. Therefore, adding an addit...
