Description
Technical Field
The invention relates to an emergency unlocking control technology of a metro vehicle door, in particular to a control method of an emergency unlocking electromagnet of the metro vehicle door.
Background
The door emergency unlocking device is installed in the passenger room of the existing subway vehicle, and is used for manually opening the subway door under abnormal conditions, such as when the subway door cannot be opened or an emergency is encountered. The unlocking device is generally an emergency unlocking handle, and three gears of initial-request-unlocking are generally set. Typically, the unlocking handle is limited by the electromagnet control to be operable only to the "demand" position when the vehicle is at a non-zero speed, and the electromagnet control is released to be operable to the "unlocking" position when the vehicle is at zero speed.
As for the control method of the emergency unlocking device, by searching for the "door emergency unlocking control method", the following two methods are mainly disclosed:
the method comprises the following steps: the emergency unlocking control system and the control method of the vehicle door authorize the bulletin number CN109372351B; the control component is electrically connected with the unlocking component and is used for displaying the request signal and sending an unlocking instruction or a prohibiting instruction to the unlocking component according to the instruction of a driver after receiving the request signal, wherein the unlocking instruction is used for releasing the limit of the stopping unit on the driving piece, and the prohibiting instruction is used for enabling the stopping unit to be maintained in a state of limiting the position of the driving piece. And the method further comprises the step of directly executing the knob unlocking operation when the unlocking instruction or the prohibiting instruction sent by the driver is not received within the preset time after the request signal is sent to the driver. The method depends on that after a driver gives a corresponding unlocking permission and unlocking prohibition signal according to a feedback request signal, if the driver does not give the unlocking permission and unlocking prohibition signal within a certain time, the knob unlocking operation is directly executed. If the vehicle is in operation, there is a risk of allowing unlocking of the door.
The second method is as follows: door emergency unlocking control method and door system, application publication number: CN111335755a. If the vehicle is in a fault power-off condition, the handle of the emergency exit device is released by the handle control structure, and the handle is allowed to operate; if not, activating a vehicle door evacuation request loop, and sending an evacuation request signal to a train signal system by the vehicle door evacuation request loop; and after the train signal system receives the evacuation request signal, controlling the vehicle to stop in a safe area so as to activate a zero-speed vehicle line signal, controlling the vehicle door to prohibit unlocking of the vehicle line signal from being invalid, and further controlling the handle to be released by the handle control structure to allow the handle to operate. The method relies on the signal control system having to have the function of automatically controlling the vehicle in response to the unlocking request signal, which is typically only done in fully automatic driving vehicles, with certain limitations. And once someone operates the unlocking handle, the vehicle is finally stopped, and if the vehicle is stopped between two stations, the operation of the line is greatly influenced.

if the metro vehicle is stopped between two stations, based on the fact that the left master gate controller and the right master gate controller receive the high level of the vehicle zero-speed signal, the master gate controller which receives the vehicle door unlocking enabling signal releases the locking of the emergency unlocking devices which respectively correspond to the vehicle doors on the same side through the slave gate controllers on the same side; for each emergency unlocking device for unlocking the requested gear, the corresponding door is opened by the emergency unlocking device from the requested gear to the unlocking gear, and the emergency unlocking control of the door of the metro vehicle is realized.
And if the metro vehicle does not stop, the vehicle door emergency unlocking device requests gear locking, and the metro vehicle continues to run.
When the vehicle runs, based on the fact that a left main gate controller and a right main gate controller receive low level of a vehicle zero-speed signal, electromagnetic valves of all vehicle door emergency unlocking devices are not powered off, stop pins are not dropped, when an unlocking handle is operated to a request gear, stop is blocked, the main gate controller sends a signal of the request gear of the emergency unlocking devices to a vehicle network control host through a network bus, a driver cab display screen prompts a person to request emergency unlocking, a specific vehicle door is displayed, the vehicle network control host is linked with a video monitoring system, a CCTV display automatically calls a corresponding camera, the vehicle network control host receives high level of the vehicle zero-speed signal on the driver cab display screen through an acoustic and optical alarm prompt according to the received request signal, after a metro vehicle is parked, the main gate controller which receives a vehicle door unlocking enabling signal is in a preset first duration, and releases the lock of each corresponding to the request gear of each emergency unlocking device of each vehicle door on the same side through each slave gate controller on the same side; for each emergency unlocking device for unlocking the requested gear, the emergency unlocking device opens the corresponding door beyond the requested gear to the unlocking gear, so that the emergency unlocking control of the door of the metro vehicle is realized, and meanwhile, the main door controller transmits the information of the received door unlocking enabling signal to the main door controller at the other side; if the main door controller at the side of opening the door does not receive the door unlocking enabling signal within the preset first time period, the main door controller at the side is based on the high level of the vehicle zero-speed signal, the emergency unlocking devices at the corresponding side edges of the main door controller at the side are unlocked through the auxiliary door controllers at the side together with the main door controller at the side, and the emergency unlocking devices pass through the request gear to unlock the corresponding doors, so that the emergency unlocking control of the doors of the subway carriage is realized;
based on the state information of a driver stopping between two stations, based on the fact that a left master gate controller and a right master gate controller receive the high level of a vehicle zero-speed signal, the master gate controller which receives a vehicle door unlocking enabling signal releases the locking of each emergency unlocking device request gear corresponding to each vehicle door on the same side through each slave gate controller on the same side; for each emergency unlocking device for unlocking the requested gear, the corresponding door is opened by the emergency unlocking device from the requested gear to the unlocking gear, and the emergency unlocking control of the door of the metro vehicle is realized.
Based on the continuous driving information of the driver, the emergency unlocking handle is limited and cannot rotate to the request position, the request gear of the vehicle door emergency unlocking device is locked, and the subway vehicle continues to drive. The influence on the normal operation of the vehicle is reduced.
If the emergency unlocking device is operated, the device must be reset before the train is restarted aiming at the situation that the emergency unlocking device in the subway carriage is in an unlocking gear, the device needs to be reset to an initial state, the subway vehicle continues to run, and otherwise, the vehicle cannot move.
The invention designs a method for controlling an emergency unlocking electromagnet of a door of a metro vehicle, which aims to solve the technical problems that the operation of the metro vehicle is influenced by vehicle parking caused by the operation of an emergency handle by passengers, or the emergency escape right of the passengers is improved under the condition that a driver is disabled after the emergency parking, or the service life of the emergency unlocking electromagnet is prolonged, and the like.
