Door auxiliary lock control method, device and rail vehicle

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to Chinese patent application No. 202410070615.5, filed on January 17, 2024, entitled “Door Auxiliary Lock Control Method, Device and Rail Vehicle,” which is incorporated herein by reference in its entirety. Technical Field

[0003] The present application relates to the technical field of rail vehicles, and in particular to a method and device for controlling a door auxiliary lock, and a rail vehicle. Background Art

[0004] Existing urban rail vehicles have doors on both sides of the passenger compartment. Upon arrival, the platform-side doors open. Specifically, the solenoid valves in the auxiliary locks on the passenger compartment doors are controlled by the "10 km train line" signal (speed signal). Since the "10 km train line" signal is not side-specific, even though only the platform-side doors open upon arrival, when the "10 km train line" signal is low (vehicle speed is less than 12 km / h), the solenoid valves in the auxiliary locks on both doors lose power, unlocking the auxiliary locks. The door controllers on the platform doors receive the door-opening command from the vehicle system and control the motors to open the doors. After passengers board and exit the vehicle, they close the doors. When the "10 km train line" signal is high (vehicle speed is greater than 30 km / h), the solenoid valves in the auxiliary locks on both doors are energized, locking the auxiliary locks on both sides. This process requires the auxiliary locks on the non-platform doors to be unlocked and locked. The simultaneous operation of both auxiliary locks generates a lot of noise, increases the number of times the auxiliary locks operate, and reduces their service life.

[0005] If the signal of the "10-kilometer train line" is to be split into two sides, additional cables will need to be laid, which will not only increase costs and occupy space but also increase failure points; and if existing vehicles need to be modified, they need to be dismantled, which will consume a lot of money and time. Summary of the Invention

[0017] According to the present application, a vehicle door auxiliary lock control method further includes:

[0018] When the target door opening side and the vehicle door side are the same and the speed signal is at a low level, start timing;

[0019] When it is detected that the auxiliary lock is not unlocked within a preset time period, the door controller is controlled to send an electrical signal to the solenoid valve corresponding to the auxiliary lock;

If the auxiliary lock cannot be unlocked within the predetermined time period after the door controller is controlled to send a power-off signal to the solenoid valve corresponding to the auxiliary lock again, an auxiliary lock fault signal is sent to the vehicle network system.

[0035] FIG3 is a schematic diagram of the gate controller structure provided in this application. DETAILED DESCRIPTION

[0036] To make the objectives, technical solutions, and advantages of this application more clear, the technical solutions of this application will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.

[0037] The vehicle door auxiliary lock control method according to an embodiment of the present application is used for a vehicle door controller, as shown in FIG1 , and includes:

[0038] Step S110: After the vehicle leaves the current station, it receives a speed signal. When the speed signal is high and the door opening information for the next station is received, the door controller is controlled to stop outputting electrical signals to the solenoid valves of the corresponding auxiliary locks. The speed signal is the "10 km train line" signal. After the vehicle leaves the current station, the number of vehicles increases. When the speed exceeds 30 km / h, the vehicle network system will send a high speed signal, energizing the solenoid valves of the auxiliary locks and locking them. When the speed signal is high, meaning all the doors' auxiliary locks are locked, the door opening information for the next station is received. Upon receiving this information, the door controller (here, the door controller for the non-platform door at the current station) is controlled to stop outputting electrical signals to the solenoid valves of the corresponding auxiliary locks. Because the speed signal is high at this time, even if the door controller stops outputting electrical signals to the solenoid valves of the corresponding auxiliary locks, the solenoid valves are already energized by the speed signal. Therefore, the solenoid valves of the auxiliary locks of the doors on both sides remain energized, and the auxiliary locks are all locked. 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 door of the current station to stop outputting electrical signals to the solenoid valve of the corresponding auxiliary lock, so as to control the door controller of the non-platform side door of the next station to output electrical signals to the solenoid valve of the auxiliary lock in the subsequent step S130.

[0039] 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 network system of the vehicle. For example, if the platform of the next station is on the left side of the vehicle based on the vehicle's forward direction, the target door opening side of the next station is the left side, that is, the left side is the platform side.

[0040] Step S120: Obtain the door side of the vehicle passenger compartment where the door controller is located. Each door corresponds to a door controller. After the vehicle is running, the entire network system of the vehicle along the direction of vehicle movement will set the door side information where the door controller is located, and send the information to the door controller for storage so that it can be obtained in real time.

[0041] Step S130: When the target door opening side and the 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 door side. The condition that the target door opening side and the door side are different is only satisfied for the door controller of the non-platform door. Therefore, the door controller of the non-platform door outputs an electrical signal to the solenoid valve of the auxiliary lock corresponding to the door side, energizing the solenoid valve to keep the auxiliary lock locked. Even when approaching the next station and the speed signal, i.e., the "10 km train line" signal, is low, the solenoid valve of the auxiliary lock of the non-platform door can still remain energized and unlocked due to the electrical signal output by the door controller of the non-platform door. For the platform side, when the speed signal, i.e., the "10 km train line" signal, is low, the solenoid valve of the auxiliary lock of the platform door loses power and unlocks.

[0042] In the vehicle door auxiliary lock control method of 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, so that the solenoid valve remains energized. Even when the vehicle is about to stop at the next station, after the speed signal is at a low level, the solenoid valve can still remain energized through the electrical signal, thereby tightening the auxiliary lock corresponding to the solenoid valve, ensuring that the auxiliary lock on the non-platform side is not unlocked, reducing the auxiliary lock operation noise and the number of times the auxiliary lock is unlocked, and improving the service life of the auxiliary lock.

[0043] In some embodiments, the door opening side information for the next stop is sent by a vehicle network system. After receiving the door opening side information for the next stop, the method further includes parsing the door opening side information for the next stop to obtain a target door opening side for the next stop. For each vehicle operation, the door opening side information for the corresponding stop is pre-set in the vehicle network system. Each time a vehicle exits a stop, the vehicle network system transmits the door opening side information for the next stop.

[0044] The door auxiliary lock control method of the above embodiment will affect the auxiliary lock unlocking and door opening function during emergency unlocking of the non-platform side door. In order to ensure the normal emergency unlocking function of the door system (regardless of whether the vehicle is stopped or running, the door will be unlocked by operating the emergency unlocking), in some embodiments, after controlling the door controller to output an electrical signal to the solenoid valve of the auxiliary lock corresponding to the door side, it also includes: receiving the auxiliary lock emergency unlocking signal, sending an emergency unlocking instruction to the solenoid valve of the corresponding auxiliary lock, causing the solenoid valve to lose power and the auxiliary lock to unlock, thereby realizing the emergency unlocking and door opening function on the non-platform side.

[0045] In some embodiments, the vehicle door auxiliary lock control method further includes:

[0046] If the received door opening command is inconsistent with the door opening side information for the next station, the door opening side information for the next station is determined to be incorrect. In this case, the incorrect door opening side information is returned to the vehicle network system. Due to various network issues, the door opening side information for the next station is incorrect. The original left side is the platform side, but the target door opening side in the door opening side information for the next station is the right side. The platform side door auxiliary lock cannot be opened, while the non-platform side door auxiliary lock is open. However, the door controller for the platform side door still receives the door opening command. Even if the non-platform side door auxiliary lock is open, the door will not open, so there is no safety hazard. It should be noted that the door opening command is an enable signal sent directly by the vehicle network system to the door controller on the platform side. After receiving the door opening command, by obtaining the door side information of the door controller corresponding to the door opening command and comparing the door side information of the door controller with the door opening side information of the next station, it can be determined whether the door opening side information for the next station is incorrect.

[0047] The vehicle network system receives the signal release command and sends it to the door controller that received the door opening command. This causes the door controller that received the door opening command to stop outputting electrical signals to the corresponding auxiliary lock's solenoid valve, effectively stopping the locking of the corresponding auxiliary lock and switching to the speed signal to control the locking and release of the auxiliary lock. At this point, since the door opening command has already been received, indicating that the speed signal is already low, the auxiliary lock's solenoid valve loses power and unlocks, allowing the door controller that received the door opening command to control the vehicle door.

[0048] In some embodiments, the vehicle door auxiliary lock control method further includes:

[0049] When the target door opening side is the same as the door side, and the speed signal is low, a timer starts, for example, 3 seconds. When the speed signal is low, the vehicle is about to enter the station and the speed is already less than 12 kilometers per hour. At this time, the solenoid valve of the auxiliary lock of the platform-side door loses power (the first time the solenoid valve loses power). Under normal circumstances, the corresponding auxiliary lock will be unlocked within 3 seconds.

[0050] If the auxiliary lock is not unlocked within a preset time period, the door controller sends an electrical signal to the solenoid valve of the corresponding auxiliary lock. The preset time period can be 3 seconds. If the auxiliary lock is not stuck, it will be unlocked within 3 seconds. If the auxiliary lock cannot be unlocked due to mechanical jamming or insufficient air pressure, the door controller sends an electrical signal to the solenoid valve of the corresponding auxiliary lock, energizing the solenoid valve and relocking the auxiliary lock (the first relock).

[0051] The door controller is controlled to send a power-off signal to the solenoid valve of the corresponding auxiliary lock (the solenoid valve loses power for the second time). After relocking, the door controller is controlled to send a power-off signal to the solenoid valve of the corresponding auxiliary lock again to unlock the auxiliary lock. Usually, if the door cannot be unlocked due to mechanical jamming or insufficient air pressure, it is likely to be unlocked successfully the second time. For example, if the unlocking is delayed for a few seconds, the air pressure is more sufficient, making the unlocking successful.

[0052] In this embodiment, the auxiliary lock is relocked and then unlocked, thereby reducing the failure rate of the vehicle door auxiliary lock being stuck and unable to be unlocked.

[0053] Furthermore, after controlling the door controller to send a power-off signal to the solenoid valve corresponding to the auxiliary lock, the method further includes:

[0054] The timer starts counting, and if the auxiliary lock is detected to be unlocked within a preset time period (for example, 3 seconds), an auxiliary lock fault signal is sent to the vehicle network system. If the auxiliary lock fails to be locked and unlocked again, it indicates that the auxiliary lock has a major fault and cannot be opened. Therefore, the auxiliary lock fault signal is sent to the vehicle network system. After receiving the auxiliary lock fault signal, the vehicle network system alerts the staff, who then mechanically locks the door corresponding to the door controller to ensure that the door cannot be opened and the vehicle can operate safely. Specifically, when the door controller sends the auxiliary lock fault signal to the vehicle network system, it will be sent along with the door controller's number or identification to the vehicle network system, so that the vehicle network system can locate the door controller with the auxiliary lock fault.

[0055] Alternatively, the timing starts, and when it is detected that the auxiliary lock is not unlocked within the preset time period, the door controller is controlled to send an electrical signal to the solenoid valve corresponding to the auxiliary lock (relocking for the second time), and the door controller is controlled to send a power-off signal to the solenoid valve corresponding to the auxiliary lock again (the solenoid valve loses power for the third time). If the auxiliary lock cannot be unlocked within the predetermined time period after the door controller is controlled to send a power-off signal to the solenoid valve corresponding to the auxiliary lock again, an auxiliary lock fault signal is sent to the vehicle network system.

[0056] It should be noted that, to ensure that the train's stop time is not affected and that train operations along the entire line are not impacted, the door controller will be prioritized for mechanical locking after the first attempt to relock and unlock the door fails, ensuring that the door cannot be opened. If the train has sufficient time to stop at the station, a second relock and unlock attempt may be considered.
