[0020] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0021] The following is combined Figures 1-4 This invention describes a local centralized door closing control method, a door system, and a vehicle.

[0022] Please refer to Figure 1 , Figure 1 This is a flowchart illustrating the local centralized control door closing method provided by the present invention.

[0023] This invention provides a locally centralized door closing control method, applied to the door control unit of a vehicle, the control method comprising:

[0024] 101: Determine the current state of the trigger switch;

[0025] 102: When the current state of the trigger switch is the door closing action state, control the door state at the preset position to be open, and control the door state at other positions to be closed.

[0026] Currently, to accommodate passenger boarding and alighting, rail vehicles keep their doors open upon arrival at stations. However, issues such as platform noise and temperature fluctuations in the passenger compartment due to external environmental factors become increasingly pronounced as the train's stop time increases, severely impacting passenger comfort. To address these technical problems, this invention provides a locally controlled door closing method. First, the vehicle's door control unit determines the current state of a trigger switch, which can be either a reset state or a closing state. The trigger switch can be a key switch, a trigger button, or another trigger mechanism. When the trigger switch is in the closing state, the door control unit controls the doors at preset positions to be open and the doors at other positions to be closed. This control method can involve the door control unit directly executing the door opening / closing operation upon receiving a control command from the vehicle control unit, or the door control unit indirectly controlling the vehicle control unit to execute the door opening / closing operation. The preset position door status can be set to open, meaning the preset position door is not closed together with other doors and is directly in the open state, or the preset position door is closed together with other doors and then opened separately.

[0027] The preset position of the car door can be selected from the door closest to the entrance of the station, and the present invention does not make any special limitation.

[0028] In summary, the local centralized door closing control method of the present invention can improve passenger cabin comfort, reduce the working pressure of the air conditioning system, achieve energy conservation and emission reduction, while preserving the passage for passengers to get on and off the vehicle, and improving the safety and reliability of the door system.

[0029] Based on the above embodiments:

[0030] In a preferred embodiment, the trigger switch is a key switch; the key switch includes a reset position and a door-closing position; determining the current state of the trigger switch includes: acquiring the current position of the key switch; if the current position of the key switch is the reset position, determining the current state of the key switch as a reset action state; if the current position of the key switch is the door-closing position, determining the current state of the key switch as a door-closing action state.

[0031] Specifically, each set of doors can be equipped with a local centralized control door closing key switch, which is a three-position switch. The middle position is the reset position, and the left and right positions can independently control a set of normally open contacts. Contacts 3 and 4 are connected to the overall vehicle centralized control door closing circuit, and contacts 1 and 6 are connected to the local door control circuit. The train attendant can turn the square key switch for operating the outer door to the centralized control door closing position to confirm that the key switch is in the door closing state. The hard wires in the overall vehicle centralized control door closing circuit and the local door control circuit are connected to the relay contacts and energized, thus activating both the overall vehicle centralized control door closing circuit and the local door control circuit. Of course, the centralized control door closing can also be canceled by resetting the door closing key switch.

[0032] In a preferred embodiment, when the current state of the trigger switch is the door closing action state, controlling the door at a preset position to be in the open state and controlling the door at a position other than the preset position to be in the closed state includes: when the current state of the trigger switch is the door closing action state, determining that the vehicle-wide centralized control door closing circuit and the local door control circuit are both active; receiving a first vehicle-wide centralized control door closing command sent by the vehicle control unit; generating a control command when the first vehicle-wide centralized control door closing command is active; controlling the door at a position other than the preset position to close based on the first vehicle-wide centralized control door closing command; and controlling the door at the preset position not to close when the local door control circuit is active.

[0033] When the vehicle control unit detects that the vehicle's centralized door closing circuit is active, it sends a local centralized door closing command (first vehicle centralized door closing instruction) to the door's door control unit. If the local centralized door closing command becomes active, and the door has not activated the "centralized door closing" square key rotary switch, and if the conditions for allowing closing are met, the door that is not fully closed will be delayed for a set time before closing. At this time, the "internal door opening button" and the "external door opening button" will become inactive.

[0034] If an obstacle is detected in the closing direction during the closing process, the obstacle detection function is normal. If the obstacle detection is activated a specified number of times and the door is fully opened, the "Local Door Close Button" light will be forcibly activated and illuminated, allowing the mechanic to close the door using the "Local Door Close Button".

[0035] During the door opening process, if the local centralized control door closing train line becomes active, the door will wait for the door to open to the correct position, and then perform the closing action after a set delay.

[0036] Only doors whose "centralized door closing" square key rotary switch has been operated will remain open, and the "inner / outer door opening button" will be operable until the door receives a valid start command. Once the train attendant has confirmed that all other doors are correctly closed, they will close their own door using the "local closing button," at which point the "outer door opening button" light will turn off. After the last door is completely closed, the train attendant can signal the driver to allow departure by reversing the "remote door closing" square key rotary switch.

[0037] The start command can be heard from the driver's cab via a bell (generated by the vehicle control unit). The start command can only be issued from the door that received the remote closing command. A bell will be generated until the door is opened or the speed signal stops sending a stop signal.

[0038] If the door is not closed, the train attendant can cancel the centralized door closing by resetting the local centralized door closing key switch on the door from which the remote closing command was issued. The vehicle control unit will then disable the local centralized door closing train line. Thus, if the conditions for allowing the door to open are met, the door will be reopened, and passengers can open the door.

[0039] The "local close button" of the door that issued the centralized close command is enabled until the door is fully closed. When the door is fully closed, all buttons are deactivated, and the centralized close command can no longer be revoked.

[0040] If you want more doors to remain open when issuing a remote closing command, you must operate the electrical emergency unlock request switch on the door before issuing the remote closing command.

[0041] The vehicle control unit can, but is not limited to, detecting the status of the vehicle's centralized door closing circuit via Ethernet.

[0042] In a preferred embodiment, when the current state of the trigger switch is the door closing action state, controlling the door at a preset position to be in the open state and controlling the doors at other positions to be in the closed state includes: when the current state of the trigger switch is the door closing action state, determining that the vehicle centralized control door closing circuit and the local door control circuit are both active; receiving a second vehicle centralized control door closing command sent by the vehicle control unit; generating a control command when the second vehicle centralized control door closing command is active; controlling all doors of the vehicle to close based on the second vehicle centralized control door closing command; and controlling the door at the preset position to open when the local door control circuit is active.

[0043] In this embodiment, when the vehicle control unit detects that the centralized door closing circuit is active, it sends a second centralized door closing command to the door control unit. The door control unit then executes the closing operation for all doors of the vehicle. At this time, the "internal door opening button" and "external door opening button" become invalid. Subsequently, when the local door control unit detects that the local door control circuit is active, it controls the door that operated the "centralized door closing" square key rotary switch to open, and the "internal / external door opening button" becomes operable. This improves passenger comfort, reduces the workload of the air conditioning system, achieves energy conservation and emission reduction, and simultaneously preserves passenger access, improving the safety and reliability of the door system.

[0044] In a preferred embodiment, when the current state of the trigger switch is the door closing action state, controlling the door at a preset position to be in the open state and controlling the door at a position other than the preset position to be in the closed state includes: when the current state of the trigger switch is the door closing action state, determining that the vehicle-wide centralized control door closing circuit and the local door control circuit are both active; when the vehicle-wide centralized control door closing circuit is active, generating a third vehicle-wide centralized control door closing command; when the local door control circuit is active, generating a control command to prevent the door at the preset position from closing; and sending the third vehicle-wide centralized control door closing command and the control command to prevent the door at the preset position from closing to the vehicle control unit, so that the vehicle control unit can control the door at a position other than the preset position to close and the door at the preset position to remain open.

[0045] In this embodiment, when the vehicle's door control unit detects that the vehicle's centralized door closing circuit is active, it sends a third vehicle centralized door closing command to the vehicle control unit. The vehicle control unit will then execute a door closing operation at a location other than the preset position. At this time, the "internal door opening button" and the "external door opening button" will become invalid.

[0046] When the vehicle's door control unit detects that the vehicle's centralized door closing circuit is active, it sends a door-keeping control command to the vehicle control unit. The vehicle control unit will then keep the door open if only the "centralized door closing" square key rotary switch has been operated, and the "inner / outer door opening buttons" will be operable. This can improve passenger comfort, reduce the workload of the air conditioning system, achieve energy conservation and emission reduction, and at the same time maintain the passage for passengers to get on and off the vehicle, thus improving the safety and reliability of the door system.

[0047] In a preferred embodiment, when the current state of the trigger switch is the door closing action state, controlling the door at a preset position to be in the open state and controlling the doors at other positions to be in the closed state includes: when the current state of the trigger switch is the door closing action state, determining that the vehicle-wide centralized control door closing circuit and the local door control circuit are both active; when the vehicle-wide centralized control door closing circuit is active, generating a fourth vehicle-wide centralized control door closing command; when the local door control circuit is active, generating a preset position door opening control command; sending the fourth vehicle-wide centralized control door closing command to the vehicle control unit to control all doors of the vehicle to close; and sending the preset position door opening control command to the vehicle control unit to control the preset position door to open.

[0048] In this embodiment, when the vehicle's door control unit detects that the vehicle's centralized door closing circuit is active, it sends a fourth centralized door closing command to the vehicle control unit. The vehicle control unit then executes the closing operation for all doors of the vehicle. At this time, the "internal door opening button" and "external door opening button" become invalid. Subsequently, when the vehicle's door control unit detects that the vehicle's centralized door closing circuit is active, it sends a door opening control command to the vehicle control unit. The vehicle control unit then controls the door that operated the "centralized door closing" square key rotary switch to open, and the "internal / external door opening buttons" become operable. This improves passenger comfort, reduces the workload of the air conditioning system, achieves energy conservation and emission reduction, and simultaneously maintains passenger access, improving the safety and reliability of the door system.

[0049] As a preferred embodiment, the method further includes: sending the detected door status of the vehicle to the vehicle control unit, the door status including one or more combinations of open door status, closed door status, emergency unlocking, and malfunction.

[0050] To further improve the safety, reliability, and comfort of door control, in this embodiment, the vehicle's door control unit can also periodically or in real time monitor the corresponding door status, which can be open, closed, emergency unlocked, or faulty.

[0051] The door control unit of the vehicle door system can be one or more, and the trigger switch can be one or more. When there are multiple door control units, each door control unit can correspond to one trigger switch, or some door control units can have corresponding trigger switches. Therefore, the vehicle door system can achieve the effect of opening a preset number of doors and closing other doors, which is more flexible. This invention does not impose any particular limitations on this.

[0052] When the door control system has multiple door control units, each corresponding to a trigger switch, one door control unit can be defined as the master door control unit, and the others as slave door control units. Each door control unit periodically or in real-time monitors the corresponding door status. To conserve the interface resources of the vehicle control unit, the slave door control units can send the detected door status to the master door control unit, which then sends it to the vehicle control unit so that the vehicle control unit can monitor the status of the train doors. Of course, doors at preset positions can close after a preset time. The closing circuit and traction circuit are interlocked. After the vehicle control unit determines that all train doors are closed within a certain time, it controls the traction system to operate, thus enabling vehicle operation. This invention does not impose any particular limitations on this.

[0056] As a preferred embodiment, it also includes a local door opening / closing button, which is used by the user to manually open or close the local vehicle door, and the local vehicle door corresponds to the local door opening button.
