Description

Technical Field

[0001] This application relates to the technical field of emergency braking abnormal control, and particularly relates to a method and system for monitoring and closed-loop control of vehicle emergency braking abnormalities. Background Art

[0002] Emergency braking means that when the train encounters an emergency during operation, the driver / passenger / on-vehicle signal system quickly operates or sends a braking command, and the braking system stops the vehicle within the shortest distance. The subway train realizes the application and relief control of emergency braking through a hard wire loop running through the vehicle. In the emergency braking safety loop, the contacts of safety relays such as driver's cab occupancy, vigilance, main air pressure, on-vehicle signal, and overspeed are usually connected in series. Based on the principle of fail-safe design, the emergency braking safety loop usually adopts a normally-energized method. When the loop loses power, the emergency braking relay loses power, and at this time, an emergency braking command is triggered; to ensure safety, once the train triggers emergency braking, generally, the safety loop needs to be re-energized and the emergency braking relieved only after the train completely stops, which is achieved by connecting the zero-speed signal in series.

[0003] The emergency braking command is transmitted to each braking control unit (i.e., BCU) through the train line level signal. The braking control unit calculates the total braking force required by the train according to the train load signal and distributes the braking force, that is, adjusts the input air pressure of the unit brake to each bogie, and is internally equipped with an independent solenoid valve control to control the on / off of the unit brake air circuit to achieve the application and relief of braking. The on-vehicle signal system is connected to the vehicle emergency braking loop through a group of nodes. When the on-vehicle signal system needs to trigger emergency braking or a fault occurs in the on-vehicle signal system, the nodes will be disconnected, causing the emergency braking loop to be disconnected, and the vehicle system will complete the emergency braking.

[0004] The reasons for the vehicle to apply emergency braking usually include the following:

[0005] Insufficient main air pressure; when the train is in the running state and the direction handle is in the zero position; the DC110V control power supply loses power; the train is separated, i.e., decoupled; the train exceeds the limit speed protection value; the driver releases the vigilance button for a long time; the driver accidentally operates the emergency braking button on the driver's console; the train has a serious fault.

[0006] Existing papers and patents related to train emergency braking mainly focus on the design of the emergency loop in order to improve the reliability of the emergency braking circuit. Since the reasons for a train to apply emergency braking are relatively independent and each is responsible for its own, all the reasons for applying emergency braking are ultimately reflected in the energization / de-energization of the train's emergency loop as components of the emergency braking loop. Emergency braking is a hard-wired logic. In the existing design and control methods, after the vehicle applies emergency braking, there is no feedback and management of the application situation, resulting in incomplete control of the application of emergency braking, which belongs to open-loop control. Once problems such as the expiration of the service life of the relay, relay adhesion accidents, aging of the hard-wired circuit, or improper / loose button contact occur, it is easy to cause abnormal release of emergency braking, that is, the emergency braking application end has operated, but the emergency braking loop still remains in its original state, and then the vehicle may experience runaway or abnormal departure, leading to serious operation risks and safety accidents. When relay adhesion, power loss of the control power supply, or electromagnetic interference occurs, it causes the emergency braking loop to disconnect, thus triggering the vehicle's emergency braking, and the abnormal stop affects operation dispatching and the personal safety of passengers. Summary of the Invention

[0007] The embodiments of the present application provide a method and system for abnormal monitoring and closed-loop control of vehicle emergency braking, which at least solve the problems in the existing design and control methods. When the vehicle applies emergency braking, there is no feedback and management of the application situation, resulting in incomplete control of the application of emergency braking, abnormal release of emergency braking, and then runaway or abnormal departure, leading to serious operation risks and safety accidents. At the same time, it solves the problems that when relay adhesion, power loss of the control power supply, or electromagnetic interference occurs, it causes the emergency braking loop to disconnect, thus triggering the vehicle's emergency braking, and the abnormal stop affects operation dispatching and the personal safety of passengers.

[0048] The present invention will be described below in conjunction with specific embodiments.

[0049] Embodiment 1

[0050] This embodiment also provides a method for monitoring and closed-loop control of vehicle emergency braking anomalies. Please refer to Figure 1 , Figure 1 which is a flowchart of the method for monitoring and closed-loop control of vehicle emergency braking anomalies according to an embodiment of the present application. As shown in Figure 1 , the method for monitoring and closed-loop control of vehicle emergency braking anomalies includes:

[0051] Step S1 of collecting emergency braking state information: TCMS obtains emergency braking state information through communication and hard-wired acquisition methods;

[0052] Step S2 of emergency braking monitoring: According to the emergency braking state information, a first monitoring result is obtained by monitoring whether there is an emergency braking trigger condition and whether there is an emergency braking loop applied;

[0053] Vehicle emergency braking control step S3: After the TCMS notifies the on-vehicle signal system and the driver and crew to perform abnormal release or abnormal application of emergency braking on the vehicle according to the monitoring result, the on-vehicle signal system and the driver and crew perform the abnormal release or abnormal application of emergency braking on the vehicle according to the content notified by the TCMS. The TCMS controls the process of applying emergency braking on the vehicle according to the result of abnormal emergency release or abnormal application of emergency braking, forming a closed-loop control.

[0054] In the embodiment, the emergency braking monitoring step S2 includes:

[0055] According to the emergency braking state information, the CCU performs logical operations to monitor whether there is an emergency braking trigger condition and whether there is an emergency braking loop applied.

[0056] In the embodiment, the vehicle emergency braking control step S3 includes:

[0057] When it is monitored that there is an emergency braking trigger condition but there is no emergency braking loop applied, the TCMS notifies the on-vehicle signal system and the driver and crew to perform abnormal release of emergency braking on the vehicle;

[0058] After a preset delay time period, within the preset delay time period, monitor whether the on-vehicle signal system and the driver and crew also apply the emergency braking loop when performing abnormal release of emergency braking on the vehicle, and obtain a second monitoring result;

[0059] If it is monitored within the preset delay time period that the on-vehicle signal system and the driver and crew do not apply the emergency braking loop when performing abnormal release of emergency braking on the vehicle, the TCMS applies the maximum service braking to the vehicle;

[0060] When it is monitored that there is no emergency braking trigger condition but there is an emergency braking loop applied, the TCMS notifies the on-vehicle signal system and the driver and crew to perform abnormal application of emergency braking on the vehicle;

[0061] After the signal system and the driver and crew perform abnormal application of emergency braking on the vehicle, the signal system remotely or the driver and crew operate the bypass to obtain emergency braking bypass information;

[0062] The TCMS applies an emergency braking bypass according to the emergency braking bypass information and controls the vehicle according to the traction braking instruction, and no longer responds to the bypassed emergency braking reason.

[0063] In specific implementation, during the train operation, in case of an emergency or dangerous situation, the emergency brake will be triggered to stop the train within the shortest distance. The triggering of the emergency brake generally includes the signal system, the anti-collision system, and the vehicle hard wire. This proposal monitors and performs closed-loop control on the emergency brake applied by the vehicle hard wire to ensure the controllability of the emergency brake application process.

[0064] The reasons for applying the emergency brake by the vehicle hard wire are as follows: insufficient main air pressure; when the train is in operation and the direction handle is in the zero position; loss of power of the DC110V control power supply; train separation, i.e., uncoupling; the train exceeds the limit speed protection value; the driver releases the vigilance button for a long time; the driver accidentally operates the emergency brake button on the driver's console; serious train faults.

[0065] As the "brain and nerves" of the train, TCMS consists of devices such as a central control unit, a man-machine interface unit, a remote input / output unit, and a communication unit. The central control unit is responsible for summarizing the operation information of each train system and issuing train control instructions. The man-machine interface unit is responsible for displaying the train operation information, status / fault information. The remote input / output unit is the hard wire circuit acquisition / control device of the train. The reasons for the vehicle to apply the emergency brake are obtained from each system through communication, and the remote input / output unit monitors the hard wire. At the same time, the remote input / output unit also monitors the status of the emergency brake loop of the entire vehicle.

[0066] In the present invention, in view of the fact that all information of the emergency brake loop can be collected through communication and hard wire, including the emergency brake application / relief output of each system, the emergency brake hard wire trigger node, and the emergency brake loop status, and then the CCU performs logical operations to carry out emergency brake cause analysis and emergency brake application status feedback: 1. When it is monitored that the emergency brake is applied, that is, the communication status or the hard wire node does not trigger the emergency brake loop, TCMS promptly notifies the on-vehicle signal system to perform emergency brake protection and reminds the driver and crew of the abnormal relief of the emergency brake through the man-machine interface unit. The on-vehicle signal and the driver apply the emergency brake again. If there is no secondary application of the emergency brake after 10 cycles, that is, the recommended time, which is not mandatory, TCMS will control the application of the maximum service brake to ensure that the vehicle stops stably as soon as possible; 2. When it is monitored that the emergency brake loop is applied but there is no emergency brake command, that is, the communication status or the hard wire node situation, TCMS promptly notifies the on-vehicle signal system and reminds the driver and crew of the abnormal application of the emergency brake through the man-machine interface unit. After the on-vehicle signal system and the driver and crew confirm, it can be bypassed through TCMS, and the vehicle operation is not affected after bypassing.

[0067] Embodiment 2

[0068] The following combines Figure 2 to explain the process steps of the emergency brake abnormal relief and protection strategy, Figure 2 is the flow chart of the emergency brake abnormal relief and protection strategy according to the embodiment of the present application. AsFigure 2 As shown in the figure, the detailed process steps are as follows:

[0069] Step 1: Based on the TCMS, all status information of each node of the emergency brake can be collected through communication and hardwiring;

[0070] Step 2: The CCU performs logical operations to analyze the cause of the emergency brake and feedback the emergency brake application status. When it is detected that the emergency brake is applied but the emergency brake trigger condition is not triggered, the operations in Steps 3 and 4 are executed; when it is detected that there is no emergency brake trigger condition but the emergency brake loop is applied, the TCMS notifies the on-vehicle signal system and the crew to perform an abnormal application of the emergency brake on the vehicle, and the operation in Step 5 is executed;

[0071] Step 3: The TCMS promptly notifies the on-vehicle signal system to perform emergency brake protection and triggers an HMI sound and light alarm through the man-machine interface unit to remind the crew of the abnormal release of the emergency brake. The on-vehicle signal and the driver apply the emergency brake again;

[0072] Step 4: If the emergency brake is not applied again within the preset time period, the TCMS will control the application of the maximum service brake to ensure that the vehicle stops steadily as soon as possible;

[0073] Step 5: The TCMS notifies the on-vehicle signal system and the crew to perform an abnormal application of the emergency brake on the vehicle. After the on-vehicle signal system and the crew confirm, the crew operates the bypass to obtain the bypass information. The TCMS applies the bypass according to the bypass information and controls the vehicle according to the traction and brake commands, does not respond to the bypassed emergency brake cause, and does not affect the vehicle operation.

[0074] Embodiment 3

[0075] This embodiment also provides a vehicle emergency brake abnormal monitoring and closed-loop control system. Figure 3 It is a vehicle emergency brake information acquisition and display diagram according to the embodiment of the present application; as Figure 4 shown, the invented vehicle emergency brake abnormal monitoring and closed-loop control system is applicable to the above-mentioned vehicle emergency brake abnormal monitoring and closed-loop control method. The vehicle emergency brake control system includes:

[0076] Emergency brake status information acquisition unit 51: Acquire emergency brake status information through the TCMS;

[0077] Emergency brake monitoring unit 52: According to the emergency brake status information, obtain the first monitoring result by monitoring whether there is an emergency brake trigger condition and whether there is an emergency brake loop application;

[0078] Vehicle emergency braking control unit 53: After the TCMS notifies the on-vehicle signal system and the driver and crew to perform abnormal mitigation or abnormal application of emergency braking on the vehicle according to the monitoring results, the on-vehicle signal system and the driver and crew perform the abnormal mitigation or abnormal application of emergency braking on the vehicle according to the content notified by the TCMS, and the TCMS controls the process of applying emergency braking on the vehicle according to the result of abnormal mitigation of emergency braking or the result of abnormal application of emergency braking.

[0079] In the embodiment, the vehicle emergency braking control unit 53 includes:

[0080] The TCMS notifies the driver and crew to perform abnormal mitigation or application of emergency braking on the vehicle through the human-machine interface unit, and the TCMS notifies the abnormal mitigation or application of emergency braking of the vehicle by interacting with the signal system host.

[0081] In summary, in the existing emergency braking of vehicles and signal systems, they are applied independently. The control of vehicle emergency braking is an open-loop design, without feedback and management of the application situation. Once the service life of the relay expires, a relay adhesion accident occurs, the hard-wired circuit ages, or the button is not touched in place / loose, it is easy to cause abnormal application / mitigation of emergency braking, and then the vehicle has abnormal parking or rolling, leading to serious operation risks and safety accidents. The vehicle emergency braking abnormal monitoring and closed-loop control method and system involved in the present invention achieve closed-loop control of vehicle emergency braking management through the TCMS, can timely monitor the state information of each node of emergency braking and the state of the emergency braking loop, track the abnormal emergency braking in various fault situations, timely notify the on-vehicle signal system and the driver and crew, re-apply emergency braking when the abnormal emergency braking is mitigated, and still can apply the maximum service braking through the TCMS under the most unfavorable conditions, which not only ensures driving safety but also facilitates troubleshooting; when the abnormal emergency braking is applied, it is convenient to troubleshoot the triggering cause and supports bypass processing to resume normal driving as soon as possible.

[0082] The above embodiments only represent several implementation manners of the present application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the protection scope of the appended claims.
