Description

Technical Field

[0001] The present invention relates to the technical field of rail vehicles, and particularly to a method and device for controlling a door auxiliary lock and a rail vehicle. Background Art

[0002] There are doors on both sides of the passenger compartment of existing suburban rail vehicles. After the vehicle arrives at the station, the doors on the platform side are opened. Specifically, the solenoid valve of the door auxiliary lock in the passenger compartment of the vehicle is controlled by the "10-kilometer train line" signal (speed signal). Since the "10-kilometer train line" signal is not side-specific, when the vehicle arrives at the station, although only the doors on the platform side are opened, when the "10-kilometer train line" signal is at a low level (vehicle speed is less than 12 kilometers per hour), the solenoid valves of the auxiliary locks on both sides of the doors will lose power, and the auxiliary locks will be unlocked. After the door controller on the platform side receives the door-opening instruction sent by the vehicle system, it controls the motor to open the door. After the passengers get on and off the vehicle and the door is closed, when the vehicle starts to leave the station and the "10-kilometer train line" signal is at a high level (vehicle speed is greater than 30 kilometers per hour), the solenoid valves of the auxiliary locks are powered on, and the auxiliary locks on both sides are locked. It can be seen that during the whole process, the auxiliary locks of the doors on the non-platform side also need to be unlocked and locked. The noise generated by the simultaneous operation of the auxiliary locks on both sides is relatively large, and the number of operations of the auxiliary locks is increased, reducing the service life of the auxiliary locks.

[0003] If the "10-kilometer train line" signal is to be divided into sides, additional cables need to be arranged, which not only increases costs, occupies space but also increases the fault points; and if existing vehicles need to be retrofitted, the vehicle needs to be disassembled, consuming a large amount of costs and time. Summary of the Invention

Obviously, the drawings in the following description are some embodiments of the present invention. For those of ordinary skill in the art, without creative efforts, other drawings can also be obtained based on these drawings.

[0033] Figure 3 is a schematic structural diagram of the door controller provided by the present invention. Detailed Embodiments

[0034] To make the objectives, technical solutions, and advantages of the present invention clearer, the following will clearly and completely describe the technical solutions in the present invention in conjunction with the drawings in the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0035] The door auxiliary lock control method of the embodiments of the present invention is used for the door controller of a vehicle, as Figure 1 shown, and includes:

[0036] Step S110: After the vehicle leaves the current station, receive the speed signal. When the speed signal is at a high level and the door opening side information of the next station is received, control the door controller to stop outputting an electrical signal to the solenoid valve of the corresponding auxiliary lock. Here, the speed signal is the "10 km train line" signal. After the vehicle leaves the current station, as the vehicle speed increases, when the speed is greater than 30 km / h, the vehicle network system will send a speed signal at a high level, and the solenoid valve of the auxiliary lock will be energized to lock the auxiliary lock. When the speed signal is at a high level, that is, when the auxiliary locks of all doors are locked, the door opening side information of the next station will be received. When this information is received, control the door controller (here the door controller is the door controller of the non-platform side doors of the current station) to stop outputting 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 outputting an electrical signal to the solenoid valve of the corresponding auxiliary lock, the solenoid valve has been energized under the trigger of this speed signal. Therefore, the solenoid valves of the auxiliary locks of each door on both sides are in an energized state, and the auxiliary locks are all in a locked state. Since the door opening side of the next station is different from that of the current station, it is necessary to first control the door controller of the non-platform side doors of the current station to stop outputting an electrical signal to the solenoid valve of the corresponding auxiliary lock, so as to facilitate controlling the door controller of the non-platform side doors of the next station to output an electrical signal to the solenoid valve of the corresponding auxiliary lock in the subsequent step S130.

[0037] 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, taking the vehicle's forward direction as a reference, if the platform of the next station is on the left side of the vehicle, then the target door opening side of the next station is the left side, that is, the left side is the platform side.

[0038] Step S120: Obtain the door side where the passenger compartment of the vehicle where the door controller is located is located. Each door corresponds to a door controller. After the vehicle starts running, the entire vehicle network system will set the door side information where the door controller is located along the vehicle running direction and send this information to the door controller for storage for real-time acquisition.

[0039] Step S130: When the target door opening side is different from the door side where the door is located, control the door controller to output an electrical signal to the solenoid valve of the auxiliary lock corresponding to the door side where the door is located. For the door controllers of the non-platform side doors, the condition that the target door opening side is different from the door side where the door is located will be met. Therefore, the door controllers of the non-platform side doors output an electrical signal to the solenoid valve of the auxiliary lock corresponding to the door side where the door is located, so that the solenoid valve is energized to keep the auxiliary lock locked. Even when the speed signal, that is, the "10 km train line" signal, is at a low level when approaching the next station, the solenoid valve of the auxiliary lock of the non-platform side doors can still be kept energized through the electrical signal output by the door controller of the non-platform side doors and will not be unlocked. For the platform side, when the speed signal, that is, the "10 km train line" signal, is at a low level, the solenoid valve of the auxiliary lock of the platform side doors will lose power and unlock.

[0040] In the door auxiliary lock control method of this embodiment, the door controller on the non-platform side (or non-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 to stop at the next station and the speed signal becomes low, the solenoid valve can still remain energized through this electrical signal, thereby pressing the auxiliary lock corresponding to the solenoid valve, ensuring that the auxiliary lock on the non-platform side is not unlocked, reducing the action noise of the auxiliary lock and the unlocking times of the auxiliary lock, and improving the service life of the auxiliary lock.

[0041] In some embodiments, the opening side information of the next station is sent by the vehicle network system. After receiving the opening side information of the next station, it further includes: parsing the opening side information of the next station to obtain the target opening side of the next station. For each operation of the vehicle, the opening side information of the corresponding station is pre-set in the vehicle network system. When the vehicle departs each time, the vehicle network system will send the opening side information of the next station.

[0042] The door auxiliary lock control method of the above embodiment will affect the unlocking and opening function of the auxiliary lock when the non-platform side door is emergently unlocked. To ensure the normal emergency unlocking function of the door system (whether the vehicle is stopped or running, operating the emergency unlocking, the door will be unlocked), 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 where it is located, it further includes: receiving the auxiliary lock emergency unlocking signal, sending an emergency unlocking instruction to the solenoid valve of the corresponding auxiliary lock to de-energize the solenoid valve, and unlocking the auxiliary lock to realize the non-platform side emergency unlocking and releasing opening function.

[0043] In some embodiments, the door auxiliary lock control method further includes:

[0044] If the received opening instruction is inconsistent with the opening side information of the next station, it is determined that the opening side information of the next station is incorrect opening side information. At this time, an incorrect opening information is returned to the vehicle network system. Due to various reasons such as the network, the opening side information of the next station is incorrect. Originally, the left side is the platform side, but in the opening side information of the next station, the target opening side is the right side. The auxiliary lock of the platform side door cannot be opened, while the auxiliary lock of the non-platform side door is opened. However, it is still the door controller on the platform side door that receives the opening instruction. Even if the auxiliary lock of the non-platform side door is opened, the door will not open, so there is no safety hazard. It should be noted that: the opening instruction is an enabling signal, which is directly sent by the vehicle network system to the door controller on one side of the platform door. After receiving the opening instruction, by obtaining the information of the door side where the door controller corresponding to the opening instruction is located and comparing the information of the door side where the door controller is located with the opening side information of the next station, it is possible to determine whether the opening side information of the next station is incorrect opening information.

[0045] Receive the unlocking signal control vehicle command sent by the vehicle network system, and send the unlocking signal control vehicle command to the door controller that has received the door opening command, so that the door controller that has received the door opening command stops outputting an electrical signal to the solenoid valve of the corresponding auxiliary lock, that is, no longer controls the corresponding auxiliary lock to lock, and switches to being controlled by the speed signal to lock and release the auxiliary lock. At this time, since the door opening command has been received, it indicates that the speed signal is already at a low level, the solenoid valve of the auxiliary lock is powered off and unlocked, and the door controller that has received the door opening command controls the door to open.

[0046] In some embodiments, the method for controlling the door auxiliary lock further includes:

[0047] When the target door opening side is the same as the side where the door is located and the speed signal is at a low level, start timing, for example: time for 3 seconds. When the speed signal is at a low level, the vehicle is about to enter the station and the vehicle speed is already less than 12 kilometers per hour. At this time, in the state where the speed signal is at a low level, the solenoid valve of the auxiliary lock on the platform side door loses power (the solenoid valve loses power for the first time). Normally, the corresponding auxiliary lock will be unlocked within 3 seconds.

[0048] In the case where it is detected that the auxiliary lock is not unlocked within the preset time period, control the door controller to send an electrical signal to the solenoid valve of the corresponding auxiliary lock. The preset time period can be 3 seconds. If there is no jamming of the auxiliary lock, it will be unlocked within 3 seconds. Since the auxiliary lock cannot be unlocked due to mechanical jamming or insufficient air pressure, etc., at this time, control the door controller to send an electrical signal to the solenoid valve of the corresponding auxiliary lock to make the solenoid valve powered on and relock the auxiliary lock (relock for the first time).

[0049] Control the door controller 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, control the door controller to send a power-off signal to the solenoid valve of the corresponding auxiliary lock again to unlock the auxiliary lock. Usually, if it cannot be unlocked due to mechanical jamming or insufficient air pressure, etc., it is very likely to be unlocked successfully during the second unlocking. For example: unlock with a few seconds delay, the air pressure is more sufficient, making the unlocking successful.

[0050] In this embodiment, by relocking and then unlocking the auxiliary lock, the failure rate of the door auxiliary lock being jammed and unable to be unlocked is reduced.

[0051] Further, after controlling the door controller to send a power-off signal to the solenoid valve of the corresponding auxiliary lock, it further includes:

[0052] Start timing. If the auxiliary lock is not unlocked within a preset time period (e.g., 3 seconds), send an auxiliary lock failure signal to the vehicle network system. If the auxiliary lock fails to relock and then unlock again, it indicates that there is a major failure with the auxiliary lock and it cannot be opened. Therefore, send an auxiliary lock failure signal to the vehicle network system. After receiving the auxiliary lock failure signal, the vehicle network system reminds the staff, enabling the staff to mechanically lock the corresponding door of the door controller to ensure that the door no longer opens and ensure the safe operation of the vehicle. Specifically, when the door controller sends an auxiliary lock failure signal to the vehicle network system, it will also send the number or identifier of the door controller to the vehicle network system so that the vehicle network system can locate the door controller where the auxiliary lock fails.

[0053] Alternatively, start timing. If the auxiliary lock is not unlocked within the preset time period, control the door controller to send an electrical signal to the solenoid valve of the corresponding auxiliary lock (second relock), and control the door controller to send a power-off signal to the solenoid valve of the corresponding auxiliary lock again (third power-off of the solenoid valve). If the auxiliary lock cannot be unlocked within a predetermined time period after the door controller sends a power-off signal to the solenoid valve of the corresponding auxiliary lock again, send an auxiliary lock failure signal to the vehicle network system.

[0054] It should be noted that: considering the vehicle's stop time and not affecting the operation of trains on the entire line, after the first relock and unlock are unsuccessful, the door controller is preferentially controlled to perform the mechanical lock closing action to ensure that the door no longer opens. If there is sufficient vehicle stop time, the second relock and unlock can be considered.
