Description

Technical Field

[0001] This application claims the priority of a Chinese patent application filed on January 17, 2024, with the application number 202410070615.5 and the invention title "Control Method, Device and Rail Vehicle for Auxiliary Lock of Vehicle Door", the whole of which is incorporated herein by reference.

[0002] This application relates to the technical field of rail vehicles, and in particular, to a control method, device and rail vehicle for an auxiliary lock of a vehicle door.

Background Art

[0003] In existing urban rail vehicles, vehicle doors are provided on both sides of the passenger compartment. After the vehicle arrives at the station, the vehicle doors on the platform side open. Specifically, the operation of the solenoid valve of the auxiliary lock of the vehicle door in the vehicle passenger compartment is controlled by the "10-kilometer train line" signal (speed signal). Since the "10-kilometer train line" signal does not distinguish between sides, when the vehicle arrives at the station, only the vehicle doors on the platform side open. However, when the "10-kilometer train line" signal is at a low level (the vehicle speed is less than 12 kilometers per hour), the solenoid valves of the auxiliary locks of the vehicle doors on both sides are both de-energized and cut off, and the auxiliary locks on both sides are unlocked together. After the door controller of the vehicle door on the platform side receives the door opening command transmitted from the vehicle system, it controls the motor to open the door. After passengers get on and off the vehicle, the vehicle door is closed. After the vehicle starts and departs from the station, when the "10-kilometer train line" signal becomes high level (the vehicle speed exceeds 30 kilometers per hour), the solenoid valve of the auxiliary lock is energized, and the auxiliary locks on both sides are locked. In the whole process, it is also necessary for the auxiliary locks of the vehicle doors on the non-platform side to be unlocked and locked. It can be seen that when the auxiliary locks on both sides operate simultaneously, a relatively large noise is generated, and the operation frequency of the auxiliary locks increases, resulting in a decrease in the service life of the auxiliary locks.

[0004] To differentiate between different tracks for the "10 km / h train line" signal would require laying additional cables, which would increase costs, expand the occupied space, and increase the number of potential failure points. Furthermore, modifying existing rolling stock would require disassembling the vehicles, consuming significant time and expense. [Overview of the project] [Problems that the invention aims to solve]

[Figure 3] It is a schematic diagram of the structure of a door controller according to the present application.

Embodiments for Carrying out the Invention

[0018] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution in the present application will be clearly and completely described below while referring to the drawings in the present application. Of course, the described embodiments are only some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the present application.

[0019] The control method for the auxiliary lock of the vehicle door according to the embodiment of the present application is used in the door controller of the vehicle. As shown in FIG. 1, it includes the following steps S110 to S130.

[0020] In step S110, after the vehicle departs from the current station, when a speed signal is received and the speed signal is at a high level and door opening side information of the next station is received, the door controller is controlled to stop the output of an electrical signal to the solenoid valve of the corresponding auxiliary lock. Here, the speed signal is a signal of the "10-kilometer train line", and after the vehicle departs from the current station, the vehicle accelerates. When the speed exceeds 30 kilometers per hour, the vehicle network system transmits a high-level speed signal, and the solenoid valve of the auxiliary lock is energized to lock the auxiliary lock. When the speed signal is at a high level, that is, when the auxiliary locks of all vehicle doors are locked, door opening side information of the next station is received. When this information is received, the door controller (here, the door controller of the non-platform side vehicle door of the current station) is controlled to stop the output of an electrical signal to the solenoid valve of the corresponding auxiliary lock. Since the speed signal is at a high level at this time, even if the door controller stops the output of an electrical signal to the solenoid valve of the corresponding auxiliary lock, the solenoid valve is energized by the trigger of the speed signal. Therefore, the solenoid valves of the auxiliary locks of each vehicle door on both sides are in an energized state, and all the auxiliary locks are in a locked state. Since the door opening side of the next station is different from the door opening side of the current station, it is necessary to first control the door controller of the non-platform side vehicle door of the current station to stop the output of an electrical signal to the solenoid valve of the corresponding auxiliary lock, so that in the subsequent step S130, the door controller of the non-platform side vehicle door of the next station is further controlled to output an electrical signal to the solenoid valve of the corresponding auxiliary lock.

[0021] The door opening side information includes the target door opening side of the next station. The door opening side information of the next station can be obtained from the entire vehicle network system. For example, based on the forward direction of the vehicle, if the platform of the next station is on the left side of the vehicle, the target door opening side of the next station is the left side, that is, the left side is the platform side.

[0022] In step S120, the location of the vehicle door side of the vehicle passenger compartment where the door controller is located is obtained. Each vehicle door corresponds to one door controller. After the vehicle starts moving, the entire vehicle network system sets the information of the vehicle door side where the door controller is located along the direction of vehicle travel, and transmits this information to the door controller for storage in real time.

[0023] In step S130, if the target door opening side and the current vehicle door side are different, the door controller is controlled to output an electrical signal to the solenoid valve of the auxiliary lock corresponding to the current vehicle door side. Only the door controller of the vehicle door on the non-platform side can satisfy the condition that the target door opening side and the current vehicle door side are different. Therefore, the door controller of the vehicle door on the non-platform side outputs an electrical signal to the solenoid valve of the auxiliary lock corresponding to the current vehicle door side, energizing the solenoid valve and maintaining the lock of the auxiliary lock. When approaching the next station, even if the speed signal, i.e., the "10 km / h train line" signal, is at a low level, the solenoid valve of the auxiliary lock on the vehicle door on the non-platform side can still be energized by the electrical signal output from the door controller of the vehicle door on the non-platform side and will not be unlocked. On the platform side, if the speed signal, i.e., the "10 km / h train line" signal, is at a low level, the solenoid valve of the auxiliary lock on the vehicle door on the platform side is de-energized and unlocked.

[0024] In the control method for the auxiliary lock of a vehicle door according to this embodiment, the door controller on the non-platform side (or non-door opening side) is controlled to output an electrical signal to the solenoid valve of the corresponding auxiliary lock. As a result, the solenoid valve remains energized, and even after the speed signal becomes low when stopping at the next station, the solenoid valve can still maintain energization due to the electrical signal. The auxiliary lock corresponding to the solenoid valve remains locked, thereby ensuring that the auxiliary lock on the non-platform side is not unlocked. This reduces the operating noise of the auxiliary lock and the number of times the auxiliary lock is unlocked, and extends the service life of the auxiliary lock.

[0025] In some embodiments, the door opening side information for the next station is transmitted from the vehicle network system, and further includes analyzing the door opening side information for the next station after receiving it, in order to obtain the target door opening side for the next station. Each time the vehicle travels, the door opening side information for the corresponding station is pre-configured in the vehicle network system, and each time the vehicle departs a station, the vehicle network system transmits the door opening side information for the next station.

[0026] The control method for the auxiliary lock of a vehicle door according to the above embodiment further includes, in some embodiments, controlling the door controller to output an electrical signal to the solenoid valve of the auxiliary lock corresponding to the vehicle door on the vehicle door side, then receiving an auxiliary lock emergency unlock signal and transmitting an emergency unlock command to the solenoid valve of the corresponding auxiliary lock, thereby cutting off the power to the solenoid valve, unlocking the auxiliary lock, and realizing the emergency unlock and door opening functions on the non-platform side when the vehicle door on the non-platform side is emergency unlocked, and ensuring the normal operation of the emergency unlock function of the vehicle door system (regardless of whether the vehicle is stopped or moving, when an emergency unlock operation is performed, the vehicle door is unlocked), and so on, when the vehicle door on the non-platform side is emergency unlocked, the unlock and door opening functions of the auxiliary lock are affected, and the normal operation of the emergency unlock function of the vehicle door system (regardless of whether the vehicle is stopped or moving, when an emergency unlock operation is performed, the vehicle door is unlocked), and so on, when the solenoid valve is emergency unlocked, the auxiliary lock is unlocked, and the emergency unlock and door opening functions on the non-platform side are realized.

[0027] In some embodiments, the method for controlling the auxiliary lock of the vehicle door is as follows: If the received door open command does not match the door open side information for the next station, the system determines that the door open side information for the next station is incorrect, and in this case, it further includes returning the incorrect door open information to the vehicle network system. Due to various reasons such as the network, the door open side information for the next station may be incorrect, and while the platform side should be on the left, if the target door open side in the door open side information for the next station is on the right, the auxiliary lock on the vehicle door on the platform side will not be released, and the auxiliary lock on the vehicle door on the non-platform side will be released. However, the door controller of the vehicle door on the platform side will still receive the door open command, and even if the auxiliary lock on the vehicle door on the non-platform side is released, the door will not open, and therefore no safety hazard will occur. The door open command is an enabling signal that is sent directly from the vehicle network system to the door controller on the platform door side. After receiving a door open command, the system can obtain information about the vehicle door where the door controller corresponding to the door open command is located, and by comparing this information with the door open information for the next station, it can determine whether the door open information for the next station is incorrect.

[0028] Upon receiving a vehicle signal control release command transmitted from the vehicle network system, the system sends a vehicle signal control release command to the door controller that received the door open command. This causes the door controller to stop outputting the electrical signal to the corresponding auxiliary lock's solenoid valve, meaning it no longer controls the locking of the corresponding auxiliary lock. Instead, the locking and unlocking of the auxiliary lock is switched to speed signal control. At this point, since the door open command has already been received, the speed signal is already at a low level. Therefore, the auxiliary lock's solenoid valve is de-energized and unlocked, and the door controller that received the door open command controls the vehicle door to open.

[0029] In some embodiments, the method for controlling the auxiliary lock of the vehicle door is as follows: If the target door opening side and the vehicle door side are the same and the speed signal is at a low level, timing is initiated, for example, for a period of 3 seconds. When the speed signal is at a low level, the vehicle is about to enter the station and its speed is already below 12 kilometers per hour. At this time, with the speed signal at a low level, the solenoid valve of the auxiliary lock on the platform-side vehicle door is de-energized (first de-energization of the solenoid valve), and under normal circumstances, the corresponding auxiliary lock is unlocked within 3 seconds.

[0030] If the system detects that an auxiliary lock has not been unlocked within a specified time period, the door controller is controlled to send an electrical signal to the corresponding auxiliary lock's solenoid valve. The specified time period may be 3 seconds, and if there is no blockage in the auxiliary lock, it should unlock within 3 seconds. If the auxiliary lock cannot be unlocked due to a mechanical blockage, insufficient air pressure, or other reasons, the door controller is controlled to send an electrical signal to the corresponding auxiliary lock's solenoid valve, energizing the valve and re-locking the auxiliary lock (first re-locking).

[0031] The door controller is controlled to send a power cut-off signal to the corresponding auxiliary lock's solenoid valve (second power cut-off to the solenoid valve). After relocking, the door controller is controlled again to send a power cut-off signal to the corresponding auxiliary lock's solenoid valve, unlocking the auxiliary lock. Generally, if unlocking is not possible due to mechanical blockage or insufficient air pressure, the second unlocking attempt is more likely to succeed, for example, after a delay of a few seconds, allowing sufficient air pressure to develop and enabling successful unlocking.

[0032] In this embodiment, the failure rate of the auxiliary lock of the vehicle door becoming jammed and unable to be unlocked is reduced by re-locking and then re-unlocking the auxiliary lock.

[0033] Furthermore, after controlling the door controller to send a power cut-off signal to the corresponding auxiliary lock solenoid valve, The system further includes starting timing and, if it detects that the auxiliary lock has not been unlocked within a predetermined time period (e.g., 3 seconds), sending an auxiliary lock failure signal to the vehicle network system. If attempts to relock and re-unlock the auxiliary lock fail, it indicates a serious failure in the auxiliary lock, rendering it impossible to unlock. Therefore, an auxiliary lock failure signal is sent to the vehicle network system, which, upon receiving the signal, alerts staff and prompts them to mechanically lock the vehicle door corresponding to the door controller. This ensures that the vehicle door cannot be opened and that the vehicle can be driven safely. Specifically, the door controller sends the auxiliary lock failure signal to the vehicle network system along with the door controller number or identifier, which allows the vehicle network system to identify the door controller that has experienced the auxiliary lock failure.

[0034] Alternatively, if timing is started and it is detected that the auxiliary lock has not been unlocked within a predetermined time period, the door controller is controlled to send an electrical signal to the solenoid valve of the corresponding auxiliary lock (second re-locking), to send a power cut-off signal to the solenoid valve of the corresponding auxiliary lock again (third power cut-off to the solenoid valve), and if the auxiliary lock cannot be unlocked within a predetermined time period after the door controller has been controlled to send a power cut-off signal to the solenoid valve of the corresponding auxiliary lock again, an auxiliary lock failure signal is sent to the vehicle network system.

[0035] Furthermore, considering the time trains spend stopped at stations, and to avoid affecting the operation of trains throughout the entire line, the door controller will be prioritized to perform a mechanical locking operation to ensure that the train doors do not open after the first attempt at re-locking and re-unlocking fails. If the train has sufficient time to stop at a station, a second attempt at re-locking and re-unlocking may also be considered.

[0036] The following describes a control device for the auxiliary lock of a vehicle door according to the present invention. The control device for the auxiliary lock of a vehicle door described below and the control method for the auxiliary lock of a vehicle door described above can be mutually referenced.

[0037] As shown in Figure 2, the control device for the auxiliary lock of a vehicle door according to the present invention includes an electrical signal stop module 210, a vehicle door side information acquisition module 220, and an electrical signal output module 230.

[0038] The electrical signal stop module 210 is for controlling the door controller to stop outputting an electrical signal to the corresponding auxiliary lock solenoid valve when the vehicle has departed the current station, and when the speed signal is at a high level and door opening information for the next station has been received, the door opening information includes the target door opening side for the next station.

This ensures that the auxiliary lock on the non-platform side is not unlocked, reducing the operating noise of the auxiliary lock and the number of times the auxiliary lock is unlocked, and extending the service life of the auxiliary lock.

[0047] Optionally, the control device for the auxiliary lock of the vehicle door further includes a power cut-off control module and a power re-energization control module.

[0048] The power cut-off control module is for starting timing when the target door opening side and the vehicle door side are the same and the speed signal is at a low level.

[0049] The re-energization control module controls the door controller to send an electrical signal to the corresponding auxiliary lock's solenoid valve if it detects that the auxiliary lock has not been unlocked within a predetermined time period.

[0050] The aforementioned power cut-off control module is further for controlling the door controller to transmit a power cut-off signal to the corresponding auxiliary lock solenoid valve.

[0051] Optionally, the vehicle door auxiliary lock control device further includes an isolation control module for starting timing after controlling the door controller to send a power cut-off signal to the solenoid valve of the corresponding auxiliary lock, and if it detects that the auxiliary lock has not been unlocked within a predetermined time period, for sending an auxiliary lock fault signal to the vehicle network system.

[0052] Alternatively, the re-energization control module further controls the door controller to send a power cut-off signal to the corresponding auxiliary lock solenoid valve, then starts timing, and if it detects that the auxiliary lock has not been unlocked within a predetermined time period, controls the door controller to send an electrical signal to the corresponding auxiliary lock solenoid valve; the power cut-off control module further controls the door controller to send a power cut-off signal again to the corresponding auxiliary lock solenoid valve; and the isolation control module further controls the door controller to send a power cut-off signal again to the corresponding auxiliary lock solenoid valve, and if the auxiliary lock cannot be unlocked within a predetermined time period, transmits an auxiliary lock failure signal to the vehicle network system.
