Description

Technical Field

[0001] This invention relates to the field of vehicle braking technology, and in particular to a door gap compensator control system, method, rail vehicle, and electronic equipment. Background Technology

[0002] The door gap compensator is used to compensate for the gap between the door and the platform. After the rail vehicle stops, the door gap compensator's pedal extends towards the platform to facilitate passengers getting on and off the train. When the train departs, the door gap compensator's pedal retracts away from the platform so as not to affect the normal operation of the train.

[0003] Existing door clearance compensator controls are all simple "flip and restore" or "extend and retract" methods. These two simple control methods are prone to causing safety hazards for passengers disembarking due to insufficient extension of the door clearance compensator, or safety hazards caused by the train exceeding clearance limits due to insufficient retraction of the door clearance compensator. Therefore, there is an urgent need for a door clearance compensator control method that improves safety. Summary of the Invention

[0004] This invention provides a door gap compensator control system, method, rail vehicle, and electronic equipment to overcome the deficiencies in the prior art.

[0006] The vehicle control unit acquires the door control signal and controls the gap compensator to extend or retract according to the door control signal;

[0007] The door control unit acquires the detection signal from the gap compensator;

[0008] If the detection signal is not received or not extended to the correct position, the vehicle control unit disconnects the working circuit of the clearance compensator, causing the clearance compensator to be in a locked state.

[0009] The door control unit receives the gap compensator locking signal and controls the door to open or close according to the door control signal.

[0010] According to the door gap compensator control system provided by the present invention, when the detection signal indicates that the door is fully extended, the door control unit controls the door to open.

[0011] When the detection signal is received, the door control unit controls the door to close.

[0012] According to a door gap compensator control system provided by the present invention, the door control signal includes a door opening centralized control command signal, a zero speed signal, and a door closing centralized control command signal;

[0013] When the door control signal is an opening control command signal or a zero speed signal, the vehicle control unit controls the gap compensator to extend according to the door control signal;

[0014] When the door control signal is a door closing control command signal, the vehicle control unit controls the gap compensator to retract according to the door control signal.

[0015] According to the present invention, a door gap compensator control system is provided, the system further comprising a central control unit.

[0016] The central control unit controls the vehicle towing operation after receiving signals that all doors of each carriage are closed in place.

[0017] According to a door gap compensator control system provided by the present invention, when the vehicle control unit obtains the door control signal again, the vehicle control unit determines not to control the gap compensator in the locked state based on the gap compensator locking signal.

[0018] According to the door gap compensator control system provided by the present invention, when the vehicle control unit obtains the door control backup mode signal and the door control signal, the vehicle control unit sends the door control signal to the door control unit, and the door control unit controls the door to open or close according to the door control signal.

[0019] According to a door gap compensator control system provided by the present invention, the door control unit acquires a single door opening command signal or a single door closing command signal and sends it to the corresponding vehicle control unit.

[0020] The vehicle control unit controls the corresponding gap compensator to extend according to the single door opening command signal, or controls the corresponding gap compensator to retract according to the single door closing command signal.

[0021] The door control unit acquires the detection signal of the corresponding gap compensator;

[0022] If the detection signal is not received or not extended to the correct position, the vehicle control unit generates clearance compensator fault information to remind the driver to handle the situation; and disconnects the working circuit of the corresponding clearance compensator, so that the clearance compensator is in a locked state.

[0023] When the detection signal is received, the door control unit controls the corresponding door to close according to a single door closing command signal;

[0024] When the detection signal indicates that the door is in the extended position, the door control unit controls the corresponding door to open according to a single door opening command signal.

[0025] The present invention also provides a door gap compensator control method, comprising:

[0026] The door control signal is obtained through the vehicle control unit, and the gap compensator is extended or retracted according to the door control signal.

[0027] The detection signal of the gap compensator is obtained through the door control unit;

[0028] If the detection signal is not received or not extended to the correct position, the vehicle control unit disconnects the working circuit of the gap compensator, thereby locking the gap compensator.

[0029] The door control unit receives the gap compensator locking signal and controls the door to open or close according to the door control signal.

[0030] The present invention also provides a rail vehicle having any of the above-mentioned door gap compensator control systems.

[0031] The present invention also provides an electronic device, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the program to implement the door gap compensator control method as described above.

[0032] The present invention also provides a non-transitory computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the door gap compensator control method as described above.

[0033] This invention provides a door gap compensator control system, method, rail vehicle, and electronic equipment. In the case of a detection signal indicating that the door gap compensator is not fully received or not fully extended, the vehicle control unit disconnects the working circuit of the gap compensator, placing the gap compensator in a locked state. The door control unit receives the gap compensator locking signal and controls the door to open or close according to the door control signal. By disconnecting the working circuit of the faulty gap compensator, it remains in a non-operating state (i.e., fully retracted), thus preventing the gap compensator from not being fully extended or retracted, thereby avoiding safety hazards and ensuring the normal operation of the vehicle.

[0040] 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.

[0041] Figure 1 This is one of the structural schematic diagrams of the door gap compensator control system provided by the present invention. Figure 2 This is the second schematic diagram of the door gap compensator control system provided by the present invention. Figure 3 This is the third schematic diagram of the door gap compensator control system provided by the present invention.

[0042] like Figure 1 , Figure 2 as well as Figure 3 As shown, the door gap compensator control system includes a vehicle control unit 10, a door control unit 20, and a gap compensator 30.

[0043] Among them, the vehicle control unit 10 is located in different compartments, and the gap compensator 30 is located at the door (e.g. Figure 3As shown, each door corresponds one-to-one with a door control unit 20. That is, each door corresponds to one gap compensator 30 and one door control unit 20, and each car's vehicle control unit 10 corresponds to n door control units 20 and gap compensators 30. The vehicle control units 10 on m cars are communicatively connected to the central control unit in the driver's cab via a train gateway. The vehicle control units 10, gap compensators 30, and door control units 20 are also communicatively connected, specifically via MVB, Ethernet, CAN bus, etc., which are not limited in this invention.

[0044] Specifically, the vehicle control unit 10 acquires the door control signal and controls the gap compensator 30 to extend or retract according to the door control signal.

[0045] It should be noted that the door control signals are sent from the central control unit in the driver's cab to the vehicle control unit 10 in each compartment.

[0046] In this embodiment, the door control signals include a door opening control command signal, a zero-speed signal, and a door closing control command signal.

[0047] Accordingly, when the door control signal is a door opening control command signal or a zero speed signal, the vehicle control unit 10 controls the gap compensator 30 to extend according to the door control signal.

[0048] When the door control signal is a door closing control command signal, the vehicle control unit 10 controls the gap compensator 30 to retract according to the door control signal.

[0049] More specifically, the vehicle control unit 10 uses the solenoid valve in the drive clearance compensator 30 to extend or retract the clearance compensator 30 according to the door control signal.

[0050] The door control unit 20 acquires the detection signal of the gap compensator 30.

[0051] Specifically, a sensor (such as a distance sensor) installed at the door is used to detect whether the pedal in the clearance compensator 30 is extended or retracted in place, thereby generating a detection signal in the clearance compensator 30 and sending it to the door control unit 20.

[0052] If the detection signal is not received or not extended to the correct position, the vehicle control unit 10 disconnects the working circuit of the gap compensator 30, so that the gap compensator 30 is in a locked state.

[0053] Specifically, after the door control unit 20 receives the detection signal and transmits it to the vehicle control unit 10, if the detection signal indicates that the pedal is not in position or the pedal is not extended, the vehicle control unit 10 cuts off the working circuit of the clearance compensator 30, thereby putting the clearance compensator 30 in a locked state.

[0054] More specifically, if the clearance compensator 30 uses a cylinder to achieve the extension and retraction of the pedal, the cylinder includes a cylinder body and a piston that extends and retracts along the cylinder body. The cylinder body is provided with an extension air inlet and a retraction air inlet, which are respectively connected to air pipes for connecting to the air supply unit. When air is supplied to the extension air inlet of the cylinder, the piston of the cylinder extends, pushing the pedal body towards the platform. After the pedal body is in place, the clearance between the platform and the vehicle is reduced. When air is supplied to the retraction air inlet, the piston moves towards the vehicle body, causing the pedal body to retract into the vehicle body. Regarding the clearance compensator 30 described above, the clearance compensator 30 can be shut off by closing the air pipes, thereby realizing the working circuit of the vehicle control unit 10.

[0055] In other embodiments of the present invention, if the clearance compensator 30 realizes the flipping extension and retraction of the pedal through the flipping hinge mechanism, the clearance compensator 30 can be disconnected by disconnecting the working power supply, thereby realizing the working circuit of the vehicle control unit 10.

[0056] The door control unit 20 receives the gap compensator locking signal and controls the door to open or close according to the door control signal.

[0057] After the vehicle control unit 10 disconnects the working circuit of the gap compensator 30 that is not fully extended or not fully retracted, the gap compensator 30 will generate a gap compensator locking signal. The vehicle control unit 10 will then obtain the gap compensator locking signal, and the door control unit 20 will also obtain the gap compensator locking signal.

[0058] After receiving the lock signal from the clearance compensator, the door control unit 20 ignores clearance compensators 30 that are not fully extended or retracted, and directly controls the door corresponding to the clearance compensator 30 that is not fully extended or retracted according to the door control signal. That is, when a clearance compensator 30 malfunctions, its working circuit is cut off, keeping it in a non-working state (i.e., fully retracted), thereby avoiding the situation where the clearance compensator 30 is not fully extended or retracted, and thus avoiding safety hazards.

[0059] When the detection signal indicates that the door is extended, the door control unit 20 controls the door to open; when the detection signal indicates that the door is received, the door control unit 20 controls the door to close. More specifically, the door control unit 20 opens or closes the door by driving the door mechanism.

[0060] According to the door clearance compensator control system provided in this embodiment of the invention, when the detection signal indicates that the door is not fully extended or not fully retracted, the vehicle control unit 10 disconnects the working circuit of the clearance compensator 30, causing the clearance compensator 30 to be in a locked state. The door control unit 20 receives the clearance compensator locking signal and controls the door to open or close according to the door control signal. By disconnecting the working circuit of the faulty clearance compensator 30, it is kept in a non-working state (i.e., a fully retracted state), thereby avoiding the situation where the clearance compensator 30 is not fully extended or retracted, thus avoiding safety hazards and ensuring the normal operation of the vehicle.

[0061] Furthermore, based on the above embodiments, the system also includes a central control unit, which is located in the driver's cab and is used to achieve overall control of the vehicle.

[0062] The central control unit controls the vehicle's traction operation after receiving signals indicating that all doors in each compartment are closed. Specifically, after the door control unit 20 drives the door mechanism to close the door, it receives the door closure signal and sends it to the central control unit. The central control unit, after collecting all the door closure signals, determines that all doors are closed and then controls the vehicle's traction operation.

[0063] Furthermore, based on the above embodiments, when the vehicle control unit 10 obtains the door control signal again, the vehicle control unit 10 determines not to control the gap compensator 30, which is in the locked state, according to the gap compensator locking signal.

[0064] In this embodiment, after the vehicle control unit 10 has disconnected the working circuit for a gap compensator 30 that is not fully extended or retracted, the vehicle control unit 10 marks the corresponding gap compensator 30 based on the gap compensator locking signal fed back by the gap compensator 30. When the vehicle control unit 10 receives a door control signal to drive the solenoid valve in the gap compensator 30, it determines, based on the marking information, to ignore control of the faulty gap compensator 30. Furthermore, during subsequent vehicle maintenance, the faulty gap compensator 30 is maintained based on the marking information.

[0065] Furthermore, based on the above embodiments, when the vehicle control unit 10 obtains the door control backup mode signal and the door control signal, the vehicle control unit 10 sends the door control signal to the door control unit 20, and the door control unit 20 controls the door to open or close according to the door control signal.

[0066] In this embodiment, if the train's control network fails, the central control unit will automatically switch to the door control backup mode and transmit the door control backup mode signal to each vehicle control unit 10 and the door control unit 20.

[0067] In the door control standby mode, after receiving the door control signal, the vehicle control unit 10 will not drive the solenoid valve in the gap compensator 30 to make the gap compensator 30 extend or retract; instead, the door control unit 20 will directly open or close the door according to the door control signal, without checking whether the gap compensator 30 is extended or retracted, and without controlling the door according to the detection signal.

[0068] The door gap compensator control system provided in the embodiments of the present invention ensures normal door opening and closing even if the vehicle experiences a control network failure through the door control backup mode, and avoids safety hazards caused by the gap compensator 30 not being fully extended or retracted.

[0069] Furthermore, based on the above embodiments, the door control unit 20 acquires a single door opening command signal or a single door closing command signal and sends it to the corresponding vehicle control unit 10.

[0070] The vehicle control unit 10 controls the corresponding gap compensator 30 to extend according to the single door opening command signal, or controls the corresponding gap compensator 30 to retract according to the single door closing command signal.

[0071] The door control unit 20 acquires the detection signal of the corresponding gap compensator 30.

[0072] If the detection signal is not received or not extended to the correct position, the vehicle control unit 10 generates a fault message for the clearance compensator 30 to remind the driver to take action; and disconnects the working circuit of the corresponding clearance compensator 30, so that the clearance compensator 30 is in a locked state.

[0073] When the detection signal is received, the door control unit 20 controls the corresponding door to close according to a single door closing command signal.

[0074] When the detection signal indicates that the door is in the extended position, the door control unit 20 controls the corresponding door to open according to a single door opening command signal.

[0075] In this embodiment, a specific door is controlled to close by a single door opening command signal or a single door closing command signal, and the process is similar to that of the door opening centralized control command signal, the zero speed signal, and the door closing centralized control command signal.

[0076] Specifically, the door control unit 20 receives a single door opening command signal or a single door closing command signal issued by the central control unit. The single door opening command signal or the single door closing command signal includes at least the door information of the specified door, and the door information corresponds to the information of the door control unit 20.

[0077] After the door control unit 20 receives a single door opening command signal or a single door closing command signal, it forwards the signal to the vehicle control unit 10. The vehicle control unit 10 controls the extension and retraction of the gap compensator 30 corresponding to the specified door (i.e., the specified gap compensator 30), and then obtains the detection signal generated by the specified gap compensator 30 through the door control unit 20.

[0078] If the detection signal is not received or not extended to the correct position, the vehicle control unit 10 generates a fault message for the specified clearance compensator 30 based on the specified clearance compensator 30 information, to remind the driver to perform maintenance on the specified clearance compensator 30. At the same time, the vehicle control unit 10 disconnects the working circuit of the specified clearance compensator 30, putting the specified clearance compensator 30 into a locked state.

[0079] When the detection signal is received or extended, the door control unit 20 directly controls the opening and closing of the door based on a single door opening command signal or a single door closing command signal.

[0080] The door gap compensator control method provided by the present invention is described below. The door gap compensator control method described below can be referred to in correspondence with the door gap compensator control system described above.

[0081] Figure 4 This is a flowchart illustrating the door gap compensator control method provided by the present invention; as shown. Figure 4 As shown, a door gap compensator control method includes:

[0082] S401, the door control signal is obtained through the vehicle control unit 10, and the gap compensator 30 is extended or retracted according to the door control signal.

[0083] In this step, the door control signals are sent from the central control unit in the driver's cab to the vehicle control unit 10 in each compartment. More specifically, the door control signals include a door opening control command signal, a zero-speed signal, and a door closing control command signal. The vehicle control unit 10, based on the door control signals, causes the clearance compensator 30 to extend or retract via the solenoid valve in the drive clearance compensator 30.

[0084] S402, the detection signal of the gap compensator 30 is obtained through the door control unit 20.

[0085] In this step, a sensor (such as a distance sensor) installed at the door is used to detect whether the pedal in the clearance compensator 30 is extended or retracted in place, thereby generating a detection signal in the clearance compensator 30 and sending it to the door control unit 20.

[0086] S403, if the detection signal is not received or not extended to the correct position, the vehicle control unit 10 cuts off the working circuit of the gap compensator 30, so that the gap compensator 30 is in a locked state.

[0087] In this step, after the door control unit 20 receives the detection signal and transmits it to the vehicle control unit 10, if the detection signal indicates that the pedal is not in position or the pedal is not extended, the vehicle control unit 10 cuts off the working circuit of the clearance compensator 30, thereby putting the clearance compensator 30 in a locked state.

[0088] More specifically, if the clearance compensator 30 uses a cylinder to achieve the extension and retraction of the pedal, the cylinder includes a cylinder body and a piston that extends and retracts along the cylinder body. The cylinder body is provided with an extension air inlet and a retraction air inlet, which are respectively connected to air pipes for connecting to the air supply unit. When air is supplied to the extension air inlet of the cylinder, the piston of the cylinder extends, pushing the pedal body towards the platform. After the pedal body is in place, the clearance between the platform and the vehicle is reduced. When air is supplied to the retraction air inlet, the piston moves towards the vehicle body, causing the pedal body to retract into the vehicle body. Regarding the clearance compensator 30 described above, the clearance compensator 30 can be shut off by closing the air pipes, thereby realizing the working circuit of the vehicle control unit 10.

[0089] In other embodiments of the present invention, if the clearance compensator 30 realizes the flipping extension and retraction of the pedal through the flipping hinge mechanism, the clearance compensator 30 can be disconnected by disconnecting the working power supply, thereby realizing the working circuit of the vehicle control unit 10.

[0090] S404, the door control unit 20 receives the gap compensator locking signal and controls the door to open or close according to the door control signal.

[0091] In this step, after the vehicle control unit 10 cuts off the working circuit of the gap compensator 30 that is not fully extended or not fully retracted, the gap compensator 30 will generate a gap compensator locking signal. The vehicle control unit 10 will then obtain the gap compensator locking signal, and the door control unit 20 will also obtain the gap compensator locking signal.

[0092] After receiving the lock signal from the clearance compensator, the door control unit 20 ignores clearance compensators 30 that are not fully extended or retracted, and directly controls the door corresponding to the clearance compensator 30 that is not fully extended or retracted according to the door control signal. That is, when a clearance compensator 30 malfunctions, its working circuit is cut off, keeping it in a non-working state (i.e., fully retracted), thereby avoiding the situation where the clearance compensator 30 is not fully extended or retracted, and thus avoiding safety hazards.

[0093] According to the door clearance compensator control method provided in this embodiment of the invention, when the detection signal indicates that the door is not fully extended or not fully retracted, the vehicle control unit 10 disconnects the working circuit of the clearance compensator 30, causing the clearance compensator 30 to be in a locked state. The door control unit 20 receives the clearance compensator locking signal and controls the door to open or close according to the door control signal. By disconnecting the working circuit of the faulty clearance compensator 30, it is kept in a non-working state (i.e., a fully retracted state), thereby avoiding the situation where the clearance compensator 30 is not fully extended or retracted, thus avoiding safety hazards and ensuring the normal operation of the vehicle.

[0094] Figure 5 An example is a schematic diagram of the physical structure of an electronic device, such as... Figure 5 As shown, the electronic device may include a processor 510, a communication interface 520, a memory 530, and a communication bus 540, wherein the processor 510, the communication interface 520, and the memory 530 communicate with each other via the communication bus 540. The processor 510 can call logical instructions in the memory 530 to execute a door gap compensator control method. This method includes: acquiring a door control signal through a vehicle control unit and controlling the gap compensator to extend or retract according to the door control signal; acquiring a detection signal of the gap compensator through the door control unit; if the detection signal is not received or not fully extended, cutting off the working circuit of the gap compensator through the vehicle control unit, causing the gap compensator to be in a locked state; receiving a gap compensator locking signal through the door control unit and controlling the door to open or close according to the door control signal.

[0095] Furthermore, the logical instructions in the aforementioned memory 530 can be implemented as software functional units and, when sold or used as independent products, can be stored in a computer-readable storage medium. Based on this understanding, the technical solution of the present invention, essentially, or the part that contributes to the prior art, or a part of the technical solution, can be embodied in the form of a software product.

[0097] In another aspect, the present invention also provides a non-transitory computer-readable storage medium storing a computer program thereon, which, when executed by a processor, implements the door clearance compensator control methods provided above. The method includes: acquiring a door control signal through a vehicle control unit and controlling the clearance compensator to extend or retract according to the door control signal; acquiring a detection signal of the clearance compensator through the door control unit; in the event that the detection signal is not received or not fully extended, cutting off the working circuit of the clearance compensator through the vehicle control unit, thereby locking the clearance compensator; and receiving a clearance compensator locking signal through the door control unit and controlling the door to open or close according to the door control signal.
