Description

TECHNICAL FIELD

[0001] The present application relates to the field of rail transit train control technology, and in particular to an automatic turn-back button sticking and sticking fault protection method, system, device and medium. BACKGROUND

[0002] With the wide application of the Communication Based Train Control System (CBTC) in the domestic rail transit industry, unmanned automatic turn-back is becoming more and more frequent in daily operation. The current unmanned automatic turn-back process under the vehicle is as follows: (1) When the vehicle-mounted controller VOBC detects that the train is stable and in the unmanned turn-back window, the MMI (Man Machine Interface) turn-back icon flashes, at which time the driver turns off the key and presses the automatic turn-back button on the driver's cab. (2) The driver gets off the train through the driver's room door and presses the automatic turn-back button in the platform area. (3) After the Computer Interlocking (CI) system detects that the platform automatic turn-back button is pressed, it forwards the button state to the zone controller (ZC), and the zone controller ZC generates a movement authorization for the vehicle-mounted controller VOBC, which controls the train to automatically run to the rear turn-back area of the station, and then to the platform after the end of the turn-back, and the driver gets on the train and turns on the key to complete the automatic turn-back process.

[0003] However, the above process has a safety hazard, that is, due to the frequent use of the platform automatic turn-back button, the reliability of the button will gradually decrease over time, which can easily cause the button to stick and stick, resulting in unintended train movement. When the driver presses the platform automatic turn-back button, the button will stick or stick, which will cause the Computer Interlocking CI to continuously collect the state that the button is pressed. In the above process, only step (1) is required to meet the conditions, and the system and the train will continue to perform steps (2)-(3). If the driver does not leave in time due to the fault, the moving train will be hung or jammed in the gap, which may cause personnel injury accidents and has a great safety hazard.

[0004] Therefore, there is an urgent need to provide a method that can effectively monitor the automatic turn-back button sticking fault and effectively protect the safety of the driver. SUMMARY

[0041] In order to make the person skilled in the art better understand the technical solutions in one or more embodiments of the present specification, the technical solutions in one or more embodiments of the present specification will be clearly and completely described below in combination with the drawings in one or more embodiments of the present specification. Obviously, the described embodiments are only a part of the embodiments of the present specification, rather than all the embodiments. Based on one or more embodiments of the present specification, all other embodiments obtained by those skilled in the art without creative labor should belong to the protection scope of the present application.

[0042] The present application will be described in detail below in combination with specific embodiments and drawings.

[0043] Method embodiment

[0044] According to the embodiment of the present application, an automatic turn-back button sticking and jamming fault protection method is provided, as shown in the figure, the automatic turn-back button sticking and jamming fault protection method provided by the present embodiment, the automatic turn-back button sticking and jamming fault protection method according to the embodiment of the present application, comprising the steps of: Figure 1

[0045] Step S1, the computer interlocking CI acquires the state of the platform automatic turn-back button in a hard-wired manner.

[0046] Step S2, when the computer interlocking CI detects that the platform automatic turn-back button is pressed, if it is detected that the platform automatic turn-back button is in a continuous activation state, the computer interlocking CI determines that the platform automatic turn-back button has sticking and jamming and starts the protection process, does not trigger the train to execute automatic turn-back action, and sends periodic alarm information to the train monitoring system.

[0047] The automatic turn-back button sticking and jamming fault protection method provided by the present embodiment, when it is detected that the platform automatic turn-back button is in a continuous activation state, it means that the button has sticking and jamming fault. In order to prevent the train from continuing to execute automatic turn-back operation, the computer interlocking CI directly enters the protection state and no longer sends indication information to the zone controller ZC, realizing the monitoring and protection of the button sticking and jamming fault, and sending corresponding alarm to the train monitoring system, prompting the operation personnel to overhaul and replace the faulty button. The method of the present embodiment is the fault monitoring of the sticking and jamming of the platform automatic turn-back button in the rail transit signal system, which effectively avoids the personnel casualty accident caused by the driver not leaving in time due to the automatic turn-back button fault.

[0048] In the present embodiment, the pressed state of the automatic turn-back button can be realized by the information acquisition mode of the computer interlocking CI, or by the feedback of the automatic turn-back button to the computer interlocking CI. The process is not limited too much.

[0049] ​The design of the entire system in this embodiment should consider the timeliness of system fault handling during train operation. The entire protection process should be designed to ensure that the train system can realize and complete it in a timely manner, and to ensure the timeliness and applicability of the fault detection and protection process of the entire system. Therefore, in order to better realize the reversal protection process under the fault state of the automatic reversal button sticking and jamming on the platform, the following specific embodiment can be referred to.

[0050] In one embodiment, when the computer interlocking CI detects that the automatic turnaround button on the platform has been pressed and remains pressed, it determines that the button is stuck and enters a protective state. In order to prevent the automatic turnaround process from continuing, the computer interlocking CI will send feedback information that the turnaround button is invalid to the area controller ZC. When the area controller ZC receives the corresponding signal, it will send feedback to the onboard controller VOBC. Since the current automatic turnaround conditions are not met, VOBC will not control the train to turn around automatically.

[0051] Further reference Figures 2-3 As shown, Figure 2 This is a flowchart illustrating the specific execution of step S1 in this embodiment. Figure 3 The corresponding embodiment provided in this example Figure 2 The flowchart shows the process flow; therefore, step S1 specifically includes the following steps:

[0052] Step S10: When the computer interlocking CI detects that the automatic reversing button on the platform has been pressed, it determines whether the button has rebounded. If the automatic reversing button does not rebound within a preset time period, it is in a continuously active state. The computer interlocking CI then determines that the button has stuck and starts the protection process.

[0053] Step S11: The computer interlocking CI sends feedback to the area controller ZC that the reversing button is invalid, and sends an automatic reversing button fault alarm to the ATS system.

[0054] Step S12: The area controller ZC forwards the invalid status of the platform turnaround button to the vehicle controller VOBC. VOBC will not trigger the train to perform automatic turnaround operation, and the ATS system will periodically send alarm information to the maintenance terminal to remind maintenance personnel to inspect the faulty button.

[0055] In this preferred embodiment, the preset time period can be set to 5-10 seconds.

[0056] In this embodiment, when the automatic turnaround button on the platform malfunctions, the computer interlocking (CI) sends feedback to the area controller (ZC) indicating that the turnaround button is invalid and prevents the VOBC from triggering the train to perform the automatic turnaround operation, thus achieving a protective state to avoid potential casualties caused by the driver not having time to leave due to the automatic turnaround button malfunction.

[0057] In another embodiment, when the computer interlocking CI detects that the platform automatic return button is pressed, and the button is in a continuously pressed state, it is determined that the button is stuck and enters a protection state, at this time in order to realize the automatic return process is no longer executed, the computer interlocking CI makes the return route of the corresponding platform in a closed state, when the area controller ZC does not detect the return route, the automatic return condition is not met, and the VOBC will not control the train to automatically return.

[0058] Further, referring to Figures 4-5 As shown in the figure, Figure 4 The step S1 provided for the embodiment specifically includes the flowchart, Figure 5 The corresponding Figure 4 The flowchart of the embodiment is shown in the figure, therefore, the step S1 specifically includes the following steps:

[0059] Step S20, when the computer interlocking CI detects that the platform automatic return button is pressed, determine whether the button is rebounded, if the automatic return button is not rebounded within a preset period, it is in a continuously activated state, then the computer interlocking CI determines that the button is stuck and starts the protection process;

[0060] Step S21, the computer interlocking CI will not handle the return route of the corresponding platform, and sends the automatic return button fault alarm information to the ATS system.

[0061] Step S22, the area controller ZC does not detect the return route feedback to the on-board controller VOBC, the on-board controller VOBC will not trigger the train to execute the automatic return operation, and the ATS system periodically sends the alarm information to the maintenance terminal to prompt the maintenance personnel to repair the fault button.

[0062] In this embodiment, in order to avoid the automatic return button from being touched by mistake, or to solve the problem that the train does not know that the automatic return button is stuck and continues to return, the automatic return trigger condition is set to be that the computer interlocking CI detects that the platform automatic return button is pressed at least twice, so that it is determined that the automatic return button is normal, and the train return action is continued.

[0063] In this embodiment, in order to avoid the existing platform automatic return button sticking and causing casualties, two automatic return buttons in series can be arranged at the platform as trigger buttons for automatic return action, and the automatic return action of the train is activated only when the two buttons are pressed at the same time. Because the probability of the two buttons being stuck or sticking at the same time is smaller than that of a single button, this design can reduce the probability of failure.

[0064] System embodiment

[0065] According to the embodiment of the present application, an automatic return button sticking and sticking fault protection system is provided, as shown inFigure 6 Fig. 1 is a schematic diagram of an automatic turn-back button sticking and jamming fault protection system provided by the embodiment, and the automatic turn-back button sticking and jamming fault protection system according to the embodiment of the application comprises a computer interlocking CI 10 and a train monitoring system 20 which are communicatively connected.

[0066] The computer interlocking CI 10 detects that the platform automatic turn-back button is pressed, and if it is detected that the platform automatic turn-back button is in a continuously activated state, it is determined that the platform automatic turn-back button is stuck and a protection process is started, the train is not triggered to perform an automatic turn-back action, and periodic alarm information is sent to the train monitoring system 20.

[0067] The automatic turn-back button sticking and jamming fault protection system provided by the embodiment, when the computer interlocking CI 10 detects that the platform automatic turn-back button is in a continuously activated state, it indicates that the button has a sticking and jamming fault. In order to prevent the train from continuing to perform an automatic turn-back operation, the computer interlocking CI 10 directly enters a protection state and no longer sends indication information to the zone controller ZC, thereby achieving monitoring and protection of the button sticking and jamming fault and sending corresponding alarms to the train monitoring system to prompt the operator to repair and replace the faulty button. The embodiment effectively avoids personnel injury accidents caused by the driver not leaving in time due to the automatic turn-back button fault in the fault monitoring of the sticking and jamming of the platform automatic turn-back button in the rail transit signal system.

[0068] In the embodiment, the pressed state of the automatic turn-back button can be achieved by information collection of the computer interlocking CI 10 or by feedback of the automatic turn-back button to the computer interlocking CI 10, and the process is not limited.

[0069] The design of the entire system of the embodiment should consider the timeliness of system fault handling in the train operation process, the entire protection process should consider that the train system can be timely realized and automatically completed, and the timeliness and applicability of the entire system fault detection and protection process should be ensured. Therefore, in order to better realize the turn-back protection control under the sticking and jamming fault state of the platform automatic turn-back button, the embodiment further comprises a zone controller ZC 30 and a vehicle-mounted controller VOBC 40, and the fault protection process is realized by the computer interlocking CI 10, the zone controller ZC 30 and the vehicle-mounted controller VOBC, and the details are as follows.

[0070] When the computer interlocking CI 10 detects that the platform automatic return button is pressed and the button is in a continuously pressed state, it is determined that the button is stuck and enters a protection state, at this time in order to realize the automatic return process no longer continues to be executed, the computer interlocking CI 10 will feedback the return button state invalid information to the area controller ZC 30, the area controller ZC 30 receives the corresponding signal and feedbacks to the vehicle-mounted controller VOBC 40, the current automatic return condition is not satisfied, and the vehicle-mounted controller VOBC 40 will not control the train to automatically return.

[0071] In a specific embodiment, the fault protection process is realized by the computer interlocking CI 10, the area controller ZC 30, the vehicle-mounted controller VOBC 40 and the ATS system 50, and the specific implementation is as follows.

[0072] The computer interlocking CI 10: detects that the platform automatic return button is pressed, determines whether the button rebounds, if it is detected that the automatic return button is in a continuously activated state within a preset period, it is determined that the button is stuck and a protection process is started, and feedbacks the return button state invalid information to the area controller ZC 30 and sends the automatic return button fault alarm information to the ATS system 50.

[0073] The area controller ZC 30: forwards the state that the platform return button is invalid to the vehicle-mounted controller VOBC 40, and the vehicle-mounted controller VOBC 40 will not trigger the train to perform the automatic return operation.

[0074] The ATS system 50: periodically sends the alarm information to the maintenance terminal to prompt the maintenance personnel to repair the faulty button.

[0075] Preferably, the preset period can be set to 5-10s.

[0076] In this embodiment, when the platform automatic return button fails, the computer interlocking CI realizes the protection state by feeding back the return button state invalid information to the area controller ZC and making the VOBC not trigger the train to perform the automatic return operation, so as to avoid personnel casualty accidents caused by the automatic return button failure and the driver not leaving in time.

[0077] In another embodiment, when the computer interlocking CI 10 detects that the platform automatic return button is pressed and the button is in a continuously pressed state, it is determined that the button is stuck and enters a protection state, at this time in order to realize the automatic return process no longer continues to be executed, the computer interlocking CI 10 makes the return route of the corresponding platform in a closed state, when the area controller ZC 30 determines that the return route is in an unopened state, the automatic return condition is not satisfied, and the vehicle-mounted controller VOBC 40 will not control the train to automatically return.

[0078] Further, the fault protection process is implemented by the computer interlocking CI 10, the zone controller ZC 30, the vehicle onboard controller VOBC 40 and the ATS system 50 as follows.

[0079] The computer interlocking CI 10: When the computer interlocking CI detects that the platform automatic return button is pressed, it is determined whether the button is rebounded, and if it is detected that the automatic return button is in a continuously activated state within a preset period, the computer interlocking CI determines that the button is stuck and starts the protection process, and the corresponding platform return route is not handled, and the automatic return button fault alarm information is sent to the ATS system.

[0080] The zone controller ZC 30: The return route is not detected and is fed back to the vehicle onboard controller VOBC, and the vehicle onboard controller VOBC will not trigger the train to perform the automatic return operation.

[0081] The ATS system 50: The alarm information is periodically sent to the maintenance terminal to prompt the maintenance personnel to repair the fault button.
