Train single-door control circuit

Abstract

The invention relates to a train single-door control circuit. The train single-door control circuit comprises a first circuit used for controlling a single door in the train dormant state and a secondcircuit used for controlling a train door in the train awakening activation state. When the train is in the dormant state, the second circuit is powered off, the first circuit works, a storage battery power source supplies power to a door control unit, and single-door control can be triggered by an electrolytic lock switch or a single-door button; and when the train is in the awakening activationstate, the first circuit is cut off, the second circuit is powered on, and under the conditions that a driver cab on the side is activated and the train is at a zero speed, single-door control is only triggered by activating the single-door button in the driver cab. Through the design, the service life of the mechanical device is guaranteed; and meanwhile, the circuit design cost and the fault rate are reduced, and the reliability is improved.

Description

technical field [0001] The invention relates to a single-door control circuit in sleep and wake-up states of rail vehicles, and is suitable for trams or unmanned trains without driver's cab doors. Background technique [0002] For traditional trams or unmanned trains, if there is no single cab door, the driver or maintenance personnel get on the train through the nearest passenger door close to the cab. Usually, only a purely mechanical device is considered to unlock a single door or a delay with a more complicated design is considered. The time and holding circuit realizes single door unlocking. [0003] The existing internal / external mechanical unlocking device is a purely mechanical structure. It is connected to an adjacent door through a wire rope, and the end unlocking device on the load-bearing drive mechanism is pulled by the wire rope to unlock, and only the door can be unlocked, and the door leaf needs to be manually unlocked. pull away.

[0002] For traditional trams or unmanned trains, if there is no single cab door, the driver or maintenance personnel get on the train through the nearest passenger door close to the cab. Usually, only a purely mechanical device is considered to unlock a single door or a delay with a more complicated design is considered. Time and holding circuit to realize single door unlocking

[0003] The existing internal / external mechanical unlocking device is a purely mechanical structure. It is connected to an adjacent door through a wire rope, and the end unlocking device on the load-bearing drive mechanism is pulled by the wire rope to unlock, and only the door can be unlocked, and the door leaf needs to be manually unlocked. pull away

[0004] The existing single-door unlocking control circuit adds relays, contactors, delay, and holding circuits, and the design of the control circuit is complicated, which increases the cost of circuit design and the failure rate
