Embodiment 1

[0025] Existing car door emergency unlocking device such as figure 1 As shown, under normal circumstances, the knob 11 on the panel is in the "reset" position. When the knob 11 is turned, the knob 11 can be directly rotated from the "reset" position to the "unlock" position, and the corresponding train door will be unlocked and then Open, at the same time, the door controller sends the signal of emergency unlocking of the door to TCMS, the HMI display screen will send a warning signal to the driver, the door safety interlock circuit will be disconnected, and the train will be blocked for traction or automatic braking. After the unlocking device is manually restored, the train can continue to operate normally.

[0026] The above-mentioned emergency unlocking device is used to artificially open the train door when the door cannot be opened or in special circumstances such as emergencies; however, if the knob 11 is arbitrarily rotated under non-special circumstances, the normal o...

Embodiment 2

[0056] Figure 6 It is a flow chart of the method for controlling emergency unlocking of the vehicle door provided by Embodiment 2 of the present invention. Such as Figure 6 As shown, the emergency door unlocking control method provided in Embodiment 2 of the present invention is used in the emergency door unlocking control system provided in Embodiment 1 of the present invention. The control method specifically includes the following steps:

[0057] S101. When the knob for unlocking the vehicle door is rotated from the initial position to the unlocked position, limit the knob to the position corresponding to the request position, and send a request signal to the driver, wherein the request position is located between the initial position and the unlock position.

[0058] In the method provided in this embodiment, the vehicle door emergency unlocking device is a device provided in one embodiment, and the stop position when the knob 11 of the device is rotated includes an ini...

Abstract

The invention provides a train door emergency unlocking system and a control method. The train door emergency unlocking system comprises a transmission assembly, an unlocking assembly and a control assembly, wherein the transmission assembly and the unlocking assembly are located in a carriage where a train door is located; the transmission assembly comprises a knob and a driving part; the stayable positions of the knob comprise an initial position, a request position and an unlocking position, wherein the request position is located between the initial position and the unlocking position, andthe driving part and the knob are connected in a linkage mode; the unlocking assembly comprises an induction unit and a stop unit; the induction unit is used for sending a request signal to the control assembly when the knob rotates to the request position; the stop unit is used for limiting the driving part at the current position when the knob rotates to the request position; and the control assembly is electrically connected to the unlocking assembly, and is used for receiving and displaying the request signal and sending an unlocking or forbidding instruction to the unlocking assembly. According to the train door emergency unlocking system, the train delay caused by the fact that passengers mistakenly operate an emergency unlocking device can be avoided, so that the influence on the operation efficiency of a train is reduced.

Description

technical field [0001] The invention relates to the technical field of emergency unlocking of train doors, in particular to a control system and method for emergency unlocking of train doors. Background technique [0002] The emergency door unlocking device, also known as the train emergency door opening device, is a device used to artificially open the subway door under abnormal circumstances, such as when the door cannot be opened or when an emergency occurs. Under the protection of the vehicle system, once the emergency door unlocking device of the train is triggered, it will cause the train to block traction or automatically brake, and it must be manually restored by a special person before it can operate normally. Therefore, in non-special circumstances, once the door emergency unlocking device is triggered, the normal operation of the train will be delayed and the normal travel of all passengers on the entire line will be hindered. [0003] Such as figure 1 , is a st...
