Chinese patent application No. 202410070615.5 filed on January 17, 2024 , entitled "Method and Device for Controlling Auxiliary Lock of Vehicle Door, and Rail Vehicle", which is hereby incorporated by reference in its entirety.
FIELD
-
The present invention relates to the field of rail vehicles, and in particular to a method and a device for controlling an auxiliary lock of a vehicle door, and a railway vehicle.
BACKGROUND
-
In traditional urban rail vehicles, vehicle doors are provided at both sides of a passenger compartment. When a vehicle arrives at a station, a vehicle door at a platform side is opened. Action of an electromagnetic valve corresponding to an auxiliary lock of the vehicle door for the passenger compartment is controlled by a "10-km train line" signal (speed signal). Since the "10-km train line" signal is not differentiated at two sides, although only the vehicle door at the platform side is opened when the vehicle arrives at a station, the electromagnetic valve corresponding to the auxiliary lock of the vehicle door at both sides is de-energized, causing all auxiliary locks to be unlocked when the "10-km train line" signal is at a low level (a vehicle speed is less than 12 kilometers per hour). Upon receiving a door opening command transmitted from a vehicle system, a door controller of the vehicle door at the platform side controls a motor to open the door. After passengers get on and off the vehicle, the vehicle door is closed. Once the vehicle departs from the station, when the "10-km train line" signal is at a high level (the vehicle speed is greater than 30 kilometers per hour), the electromagnetic valve corresponding to the auxiliary lock is energized, causing the auxiliary locks at both sides to be locked. Throughout the entire process, an auxiliary lock of a vehicle door at a non-platform side also needs to be unlocked and locked. Simultaneous actions of the auxiliary locks at both sides generate significant noise, increases the number of actions for the auxiliary locks, and reduces the service life of the auxiliary locks.
-
To differentiate the "10-km train line" signal at two sides, additional cables are required, not only increasing costs, occupying more spaces, but also adding failure points. Moreover, if current vehicles need to be modified, they need to be dismounted, consuming significant time and resources.

DETAILED DESCRIPTION
-
To clearly illustrate the purpose, solutions and advantages of the present invention, the solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. These embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without any creative effort belong to the scope of the present invention.
-
A method for controlling an auxiliary lock of a vehicle door according to an embodiment of the present invention is used for a door controller of a vehicle, as shown in FIG. 1, and includes:
step S110: after a vehicle departs from a current station, receiving a speed signal, and controlling, when the speed signal is at a high level and door opening side information for the next station is received, a door controller to stop outputting an electrical signal to an electromagnetic valve corresponding to the auxiliary lock. The speed signal refers to a "10-km train line" signal. After departing from the current station, the vehicle accelerates. When the speed exceeds 30 km/h, the vehicle network system may transmit a speed signal at a high level, and the electromagnetic valve corresponding to the auxiliary lock is energized to lock the auxiliary lock. When the speed signal is at a high level, i.e., the auxiliary locks of all vehicle doors are locked, the door opening side information for the next station may be received. Upon receiving the information, the door controller (here referring to a door controller of the vehicle door on the non-platform side of the current station) is controlled to stop outputting an electrical signal to an electromagnetic valve corresponding to the auxiliary lock. Since the speed signal is at a high level at this time, even if the door controller stops outputting the electrical signal to the electromagnetic valve corresponding to the auxiliary lock, this electromagnetic valve remains energized under the triggering of the speed signal. Therefore, the electromagnetic valves corresponding to 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. As the door opening side of the next station is different from that of the current station, the door controller of the vehicle door on the non-platform side of the current station is first controlled to stop outputting an electrical signal to the electromagnetic valve corresponding to the auxiliary lock. This facilitates the subsequent step S130 where the door controller of the vehicle door on the non-platform side of the next station is controlled to output the electrical signal to the electromagnetic valve corresponding to the auxiliary lock.
-
The door opening side information includes a target door opening side of the next station. The door opening side information for the next station may be acquired from the entire network system of the vehicle. For example, with the vehicle's approaching direction as a reference, if a 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, i.e., the left side serves as the platform side.
-
Step S120: acquiring a vehicle door side of a passenger compartment where the door controller is located. Each vehicle door corresponds to one door controller. After the vehicle starts running, the entire network system of the vehicle along the vehicle's movement direction may set vehicle door side information of the position where the door controller is located, and transmit the information to the door controller for storage, enabling real-time acquisition.
-
Step S130: when the target door opening side is different from the vehicle door side, controlling the door controller to output an electrical signal to an electromagnetic valve corresponding to the auxiliary lock corresponding to the vehicle door side. Only a door controller of the vehicle door on the non-platform side may satisfy the condition where the target door opening side is different from the vehicle door side. Therefore, the door controller of the vehicle door on the non-platform side outputs an electrical signal to the electromagnetic valve corresponding to the auxiliary lock corresponding to the door side, energizing the electromagnetic valve to maintain the locked state of the auxiliary lock. Even when the vehicle approaches the next station, and the speed signal, i.e., the "10-km train line" signal, is at a low level, the electromagnetic valve corresponding to the auxiliary lock corresponding to the vehicle door on the non-platform side may still remain energized via the electrical signal output from the door controller of the vehicle door on the non-platform side, and thus is not unlocked. For the platform side, when the speed signal, i.e., the "10-km train line" signal, is at a low level, the electromagnetic valve corresponding to the auxiliary lock corresponding to the vehicle door on the platform side is de-energized and unlocked.
-
In a method for controlling an auxiliary lock of a vehicle door according to the embodiment, a door controller on the non-platform side (or non-door opening side) is controlled to output an electrical signal to an electromagnetic valve corresponding to the auxiliary lock, causing the electromagnetic valve to keep in an energized state. Even when the vehicle is about to stop at the next station and the speed signal is at a low level, the electromagnetic valve remains energized via the electrical signal, to lock the auxiliary lock corresponding to the electromagnetic valve, which ensures that an auxiliary lock on a non-platform side is not unlocked, and both the action noise of the auxiliary lock and the number of instances of unlocking of the auxiliary lock are reduced to prolong the service life of the auxiliary lock.
-
In some embodiments, the door opening side information for the next station is transmitted from a vehicle network system, and after receiving the door opening side information for the next station, the method further includes: parsing the door opening side information of the next station to acquire the target door opening side of the next station. Every time the vehicle operations, door opening side information for the corresponding station is preset in the vehicle network system. Every time the vehicle departs from the station, the vehicle network system transmits door opening side information for the next station.
-
The method for controlling an auxiliary lock of a vehicle door according to the above embodiments affects the auxiliary lock unlocking and door opening function during emergency unlocking of the vehicle door on the non-platform side. In some embodiments, to ensure the normal operation of an emergency unlocking function for the vehicle door system (regardless of whether the vehicle is stopped or running, the vehicle door is unlocked by operating the emergency unlocking), after controlling the door controller to output an electrical signal to the electromagnetic valve corresponding to the auxiliary lock corresponding to the vehicle door side where the door controller is located, the method further includes: receiving an emergency unlocking signal for the auxiliary lock and transmitting an emergency unlocking command to an electromagnetic valve corresponding to the auxiliary lock. This command de-energizes the electromagnetic valve and unlocks the auxiliary lock, thereby realizing the emergency unlocking on the non-platform side and enabling the door opening function.
-
In some embodiments, the method for controlling the auxiliary lock of the vehicle door further includes:
when a door opening command received is inconsistent with the door opening side information for the next station, determining that the door opening side information for the next station is incorrect door opening side information. In this case, incorrect door opening information is returned to the vehicle network system. Due to various reasons such as the network, the door opening side information for the next station is an incorrect information. For example, while the platform side should be on the left, the target door opening side in the door opening side information for the next station is on the right. Consequently, an auxiliary lock of the vehicle door on the platform side cannot be opened, whereas an auxiliary lock of the vehicle door on the non-platform side is opened. However, the door controller of the vehicle door on the platform side still receives the door opening command. Since the vehicle door on the non-platform side cannot be opened even if the auxiliary lock of the vehicle door on the non-platform side is released, there is no safety hazard. It should be noted that, the door opening command is an enable signal directly transmitted from the vehicle network system to the door controller on the platform side. Upon receiving the door opening command, the door controller on the platform side acquires the vehicle door side information corresponding to the door opening command where the door controller is located, and the vehicle door side information where the door controller is located is compared with the door opening side information for the next station. In this manner, it determines whether the door opening side information for the next station is the incorrect door opening information.
-
The signal-controlled vehicle release command transmitted from a vehicle network system is received, and the signal-controlled vehicle release command is transmitted to the door controller receiving the door opening command to allow the door controller receiving the door opening command to stop outputting an electrical signal to an electromagnetic valve corresponding to the auxiliary lock, which means that it no longer controls the locking of the corresponding auxiliary lock. Instead, the locking and release of the auxiliary lock are switched to be controlled by the speed signal. In this case, since the door opening command has already been received, it indicates that the speed signal is already at a low level. The electromagnetic valve corresponding to the auxiliary lock is de-energized and unlocked, and the door controller receiving the door opening command controls the vehicle door to be opened.
-
In some embodiments, the method for controlling an auxiliary lock of a vehicle door further includes:
starting a timer when the target door opening side is the same as the vehicle door side and the speed signal is at a low level, for example, 3 seconds. When the speed signal is at a low level, a vehicle is about to enter a station and the speed is already less than 12 km/h. In this case, when the speed signal is at a low level, the electromagnetic valve corresponding to the auxiliary lock corresponding to the vehicle door on the platform side is de-energized (first de-energization of the electromagnetic valve). Under normal circumstances, the corresponding auxiliary lock will be unlocked within 3 seconds.
-
In case of detecting that the auxiliary lock is not unlocked within a preset time period, the door controller is controlled to transmit an electrical signal to the electromagnetic valve corresponding to the auxiliary lock. The preset time period may be set to 3 seconds. If there is no jamming in the auxiliary lock, the auxiliary lock may be unlocked within 3 seconds. When the auxiliary lock cannot be unlocked due to mechanical jamming or insufficient air pressure, the door controller is controlled to transmit an electrical signal to the electromagnetic valve corresponding to the auxiliary lock, to energize the electromagnetic valve to re-lock the auxiliary lock (first re-locking).
-
The door controller is controlled to transmit a de-energization signal to the electromagnetic valve corresponding to the auxiliary lock (second de-energization of the electromagnetic valve). After re-locking, the door controller is again controlled to transmit a de-energization signal to the electromagnetic valve corresponding to the auxiliary lock, allowing the auxiliary lock to unlock. Generally, in case that to the failure to unlock is caused by issues such as mechanical jamming or insufficient air pressure, the auxiliary lock is most likely to be unlocked successfully during the second unlocking attempt. For example, unlocking may succeed with a few seconds of delay, or when the air pressure becomes sufficient enough to enable unlocking.
-
In this embodiment, the auxiliary lock is re-locked and then unlocked again, which helps reduce the failure rate of the auxiliary lock of the vehicle door failing to unlock due to jamming.
-
After controlling the door controller to transmit a de-energization signal to the electromagnetic valve corresponding to the auxiliary lock, the method further includes:
- starting a timer, and in case of detecting that the auxiliary lock is not unlocked within a preset time period (e.g., 3 seconds), transmitting a signal that the auxiliary lock is fault to the vehicle network system. If the auxiliary lock is not unlocked after relocking and re-unlocking attempts, it indicates that the auxiliary lock has a major fault and cannot be locked. Therefore, the signal that the auxiliary lock is fault is transmitted to the vehicle network system. After receiving the signal that the auxiliary lock is fault, the vehicle network system alerts staff, prompting them to mechanically lock the vehicle door corresponding to the door controller. This ensures that the vehicle door remains closed and guarantees the safe operation of the vehicle. Specifically, the door controller transmits the signal that the auxiliary lock is fault to the vehicle network system, together with the serial number or identifier of the door controller, enabling the vehicle network system to locate the door controller with the faulty auxiliary lock; or
- starting a timer, and in case of detecting that the auxiliary lock is not unlocked within a preset time period, controlling the door controller to transmit the electrical signal to the electromagnetic valve corresponding to the auxiliary lock (second re-locking), and controlling the door controller to transmit the de-energization signal to the electromagnetic valve corresponding to the auxiliary lock again (third de-energization of the electromagnetic valve). When the auxiliary lock cannot be unlocked within the preset time period after controlling the door controller to transmit a de-energization signal to the electromagnetic valve corresponding to the auxiliary lock again, a signal that the auxiliary lock is fault is transmitted to the vehicle network system.
-
It should be noted that, in consideration of the vehicle's station stop time to avoid affecting the operation of the train on the entire line, if the first re-locking and re-unlocking attempt fails, the door controller is prioritized to be controlled to perform the mechanical locking action, to ensure that the door remains closed. If the vehicle has sufficient time to stop at a station, a second re-locking and re-unlocking attempt may be considered.
