Abstract

Provided are a method and system for controlling a vehicle door and lighting during rail vehicle cleaning. By activating a locked vehicle mode, a vehicle door is controlled to be closed and locked, and lighting is simultaneously controlled to be turned off. By activating a cleaning mode, a local door switch is allowed to control a vehicle door switch and the lighting is simultaneously controlled to be turned on. When sanitary cleaning is being carried out, vehicle door and lighting control in a cab is not needed, and cooperation of professional maintenance personnel or drivers is not needed, thus saving manpower and material resources. Meanwhile, in the locked vehicle mode, the vehicle door cannot be opened by means of an emergency unlocking device, thus preventing persons other than professional maintenance personnel, a driver or a cleaner from entering the vehicle, thereby enhancing management of personnel boarding the vehicle, reducing potential safety hazards, and ensuring vehicle safety.

Description

Method, system and vehicle for controlling door and lighting of rail vehicle during cleaning

Technical field

The invention belongs to the technical field of vehicle lighting and door control, and in particular relates to a method, system and vehicle for controlling the door and lighting of a rail transit vehicle during cleaning.

Background technique

Rail transit vehicles, such as EMU trains and high-speed rail trains, need to clean their interiors after operation to ensure normal operation the next day. During sanitation and cleaning, the interior lighting and door opening and closing control are required, and the control switches or buttons for lighting and doors are arranged in the driver’s cab. Therefore, during sanitation and cleaning, professional maintenance personnel or drivers are required to monitor the doors and lighting on the vehicle. And operation, wasting manpower and material resources. At the same time, when the vehicle is parked at the station without power for a long time, other personnel can open the door of the vehicle through the emergency unlocking device to enter the vehicle, which is inconvenient for the management of the personnel on the vehicle, and there is a potential safety hazard.

Summary of the invention

In view of the shortcomings of the prior art, the present invention provides a method, system and vehicle for controlling the door and lighting of a rail vehicle during cleaning, so as to solve the problem of controlling the door and lighting of the rail vehicle during cleaning.

The present invention solves the above-mentioned technical problems through the following technical solutions: A method for controlling the door and lighting of a rail vehicle during cleaning, including:

Step 1: In the parking mode, activate the lock mode, and control the door to close and lock the door according to the lock mode activation signal, and at the same time control the lighting to turn off; when the lock mode is activated, the door cannot be opened through the emergency unlocking device;

Step 2: When cleaning is needed, turn off the lock mode. When the lock mode is turned off, open the door through the emergency unlocking device;

Step 3: Activate the cleaning mode, and control the door permission switch according to the cleaning mode activation signal, and control the lighting to turn on at the same time; when the cleaning mode is activated, the local door switch is used to control the opening and closing of the door;

Step 4: After the cleaning is completed, turn off the cleaning mode, restrict the control of the door by the local door switch, and activate the lock mode again.

The control method of the present invention closes and locks the car door and turns off the lighting through the car lock mode activation signal. In the car lock mode, the car door cannot be opened by the emergency unlocking device; when cleaning is needed, the car lock mode is turned off, and the car door is unlocked by emergency The device opens the car door, the cleaner enters the car, and then controls the door permission switch through the cleaning mode activation signal, that is, the local door switch can be used to control the opening and closing of the car door, and the lighting can be controlled at the same time; after the cleaning is finished, the cleaning mode is turned off and activated again In the car lock mode, the car door is controlled to be closed and locked through the car lock mode activation signal, and the lighting is turned off at the same time; the control method of the present invention does not need to control the car door and lighting in the driver's cabin, so there is no need for professional maintenance personnel or the driver to cooperate when cleaning The door and lighting can be controlled to facilitate vehicle maintenance and reduce the waste of manpower and material resources. At the same time, in the lock mode, the door cannot be opened through the emergency unlocking device, which prevents professional maintenance personnel, drivers or cleaning personnel from entering the vehicle.
