Description

Technical Field

[0001] This application relates to the field of train control technology, and in particular to a test method and apparatus for clearing fault protection zones. Background Technology

[0002] During operation, trains continuously transmit their real-time location to the Radio Block Center (RBC). The RBC combines this data with information such as ground track conditions, forward signals, and the train's real-time position to calculate the Moving Authorization (MA) and issue it to the train for safe operation. However, communication with the RBC can sometimes be interrupted, preventing the RBC from obtaining the train's real-time location and thus from calculating the MA. Consequently, the train cannot obtain the MA for safe operation. Therefore, when communication with the RBC is interrupted, a fault protection zone is established for the train with the interrupted communication, preventing other trains from entering and ensuring the safety of the train with the interrupted communication.

[0003] Typically, after setting up a fault protection zone for a train, it needs to be deactivated to restore normal operation of the trains within the fault protection zone. However, if the deactivation of the fault protection zone occurs incorrectly or abnormally, it can threaten the operational safety of the trains. Therefore, whether the fault protection zone can be deactivated correctly directly affects the operational safety of the trains within the fault protection zone. Thus, it is necessary to test the deactivation of fault protection zones to determine whether they can be deactivated correctly. Therefore, how to accurately test whether the deactivation of fault protection zones can be correctly implemented has become an urgent problem to be solved. Summary of the Invention

[0004] This application proposes a test method and apparatus for disabling fault protection zones, the main purpose of which is to accurately test whether fault protection zones can be correctly disabled.

[0005] To achieve the above objectives, this application mainly provides the following technical solutions:

[0006] Firstly, this application provides a testing method for removing fault protection zones. The testing method for removing fault protection zones provided in this embodiment may include: controlling a target train running on a target line to interrupt communication with the radio block center; detecting whether the target fault protection zone set up by the radio block center for the target train on the target line due to communication interruption is marked by a target color light strip on the CTC station map of the dispatching centralized system; if so, selecting a target object for removing the fault protection zone from the target train, the radio block center, and the dispatching centralized system; controlling the target object to perform a corresponding action for removing the fault protection zone; detecting whether the target color light strip can disappear from the CTC station map based on the target object performing the corresponding action; if so, determining that the test for removing the fault protection zone has passed.

[0007] In some embodiments of this application, if the target object includes the target train, then controlling the target object to perform corresponding actions to remove the fault protection zone includes: controlling the target train to continue running forward along the target line in a visual driving mode until it reaches the track in the station ahead;

[0008] Then, detecting whether the target color light band can disappear from the CTC station diagram by performing a corresponding action based on the target object includes: detecting whether the portion of the target color light band located behind the tail protection position of the target train disappears from the CTC station diagram as the target train moves forward, and whether the target color light band completely disappears from the CTC station diagram when the target train reaches the track of the next station; if the portion located behind the tail protection position of the target train disappears from the CTC station diagram, and the target train reaches the track of the next station... If the target color light band disappears completely from the CTC station diagram when the target train is running on a track in the station ahead, then it is detected that the target color light band can perform the corresponding action based on the target object to disappear from the CTC station diagram; if the portion located after the tail protection position of the target train cannot disappear from the CTC station diagram, and / or, if the target color light band does not disappear completely from the CTC station diagram when the target train runs on a track in the station ahead, then it is detected that the target color light band cannot perform the corresponding action based on the target object to disappear from the CTC station diagram.

[0009] In some embodiments of this application, if the target object includes the target train and the radio block center, then controlling the target object to perform corresponding actions for clearing the fault protection zone includes: controlling the target train to stop at the position where communication was interrupted, and controlling the target train to resume communication with the radio block center;

[0010] Then, detecting whether the target color light band can disappear from the CTC station map by performing a corresponding action based on the target object includes: detecting whether the target color light band completely disappears from the CTC station map when the target train and the radio block center resume communication; if it disappears, it is detected that the target color light band can disappear from the CTC station map by performing a corresponding action based on the target object; if it does not disappear, it is detected that the target color light band cannot disappear from the CTC station map by performing a corresponding action based on the target object.

[0011] In some embodiments of this application, after detecting that the target color light band can perform a corresponding action based on the target object and disappear from the CTC station map, the test method for removing the fault protection zone provided in this embodiment further includes: determining whether the end position of the train operation permission displayed in the onboard human-machine interface device (DMI) of the target train has been restored to the end position of the train operation permission used when the communication was interrupted; if yes, then the step of determining that the test for removing the fault protection zone has passed is performed; if no, then the test for removing the fault protection zone has failed is determined.

[0012] In some embodiments of this application, if the target object includes the target train and the radio block center, then controlling the target object to perform corresponding actions to remove the fault protection zone includes: controlling the target train to continue running forward along the target line in backup mode until it stops after reaching the designated block section ahead; and controlling the target train to resume communication with the radio block center after the target train stops.

[0013] Then, detecting whether the target color light band can disappear from the CTC station map by performing a corresponding action based on the target object includes: detecting whether the target color light band disappears completely or partially from the CTC station map during the process of the target train moving forward and stopping at the designated block section ahead; if yes, then it is detected that the target color light band cannot disappear from the CTC station map by performing a corresponding action based on the target object; if no, then it is detected whether the target color light band disappears completely from the CTC station map when the target train and the radio block center resume communication; if it disappears, then it is detected that the target color light band can disappear from the CTC station map by performing a corresponding action based on the target object; if it does not disappear, then it is detected that the target color light band cannot disappear from the CTC station map by performing a corresponding action based on the target object.

[0014] In some embodiments of this application, if the target object includes the target train and the dispatching centralized system, then controlling the target object to perform corresponding actions for releasing the fault protection zone includes: controlling the target train to stop at the position when communication is interrupted; and in the operation interface of the dispatching centralized system, sequentially performing the release protection zone operation on the block sections involved in the target fault protection zone along the running direction of the target train.

[0015] The detection of whether the target color light band can disappear from the CTC station map by performing a corresponding action based on the target object includes: after each block section involved in the target fault protection area is released from protection, detecting whether the part of the target color light band corresponding to the block section disappears from the CTC station map. If it disappears, the release operation is performed on the next block section. If it does not disappear, it is detected that the target color light band cannot disappear from the CTC station map by performing a corresponding action based on the target object. If all block sections involved in the target fault protection area are released from protection, it is detected whether the target color light band disappears completely from the CTC station map. If it disappears completely, it is detected that the target color light band can disappear from the CTC station map by performing a corresponding action based on the target object. If it does not disappear completely, it is detected that the target color light band cannot disappear from the CTC station map by performing a corresponding action based on the target object.

[0016] In some embodiments of this application, the test method for removing fault protection zones provided in this embodiment may further include: after detecting that the target fault protection zone set up by the radio block center for the target train on the target line due to communication interruption is marked by a target color light strip on the CTC station map of the dispatching centralized system, detecting whether the destination position of the target train's driving permission displayed on the on-board human-machine interface device (DMI) of the target train has changed to the position of the front of the target train; if yes, then performing the step of selecting a target object for removing the fault protection zone from the target train, the radio block center, and the dispatching centralized system; if no, then determining that the test for removing the fault protection zone has failed.

[0017] In some embodiments of this application, the test method for removing the fault protection zone provided in this embodiment may further include: if it is detected that the target color light band cannot perform the corresponding action based on the target object and disappear from the CTC station map, then it is determined that the test for removing the fault protection zone has failed;

[0018] The test method for removing the fault protection zone provided in this embodiment may further include: the target color light band is a pink light band.

[0019] Secondly, this application provides a test apparatus for removing fault protection zones. The test apparatus for removing fault protection zones provided in this embodiment includes:

[0020] The first control module is used to control the interruption of communication between the target train running on the target line and the radio block center.

[0021] The first detection module is used to detect whether the target fault protection zone set up by the radio block center for the target train on the target line by the target color light band on the CTC station map of the dispatching centralized system is marked by the target color light band; if so, the selection module is triggered to select the target object from the target train, the radio block center and the dispatching centralized system to remove the fault protection zone.

[0022] The second control module is used to control the target object to perform corresponding actions to remove the fault protection zone;

[0023] The second detection module is used to detect whether the target color light band can disappear from the CTC station map by performing the corresponding action based on the target object; if it can, the determination module is triggered to determine that the test to remove the fault protection zone has passed.

[0024] Thirdly, this application provides a computer-readable storage medium including a stored program, wherein, when the program is executed, it controls the device where the storage medium is located to perform the test method for clearing the fault protection zone described in the first aspect.

[0025] Fourthly, this application provides an electronic device, the electronic device comprising: a memory for storing a program; and a processor coupled to the memory for running the program to perform the test method for removing fault protection zones as described in the first aspect.

[0026] The testing method and apparatus for clearing fault protection zones provided in this application, when testing the clearing of fault protection zones, control the interruption of communication between the target train running on the target line and the radio block center. It detects whether the target fault protection zone set up by the radio block center for the target train on the target line due to communication interruption is marked by a target color light band on the CTC station map of the centralized dispatching system. If the target fault protection zone is detected by the target color light band, a target object for clearing the fault protection zone is selected from the target train, the radio block center, and the centralized dispatching system, and the target object is controlled to perform the corresponding action for clearing the fault protection zone. Then, it detects whether the target color light band can disappear from the CTC station map based on the target object performing the corresponding action. If the target color light band can disappear from the CTC station map based on the target object performing the corresponding action, the test for clearing the fault protection zone is determined to be passed. As can be seen, the solution provided in this application selects the target object for removing the fault protection zone from the target train, the radio block center, and the centralized dispatching system, and controls the target object to perform the corresponding actions for removing the fault protection zone, so as to test the removal of the fault protection zone and determine whether the fault protection zone can be correctly removed. In this way, after the train is put into operation, the fault protection zone can be accurately removed, thereby ensuring the safe operation of the train.

[0033] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0034] A fault protection zone is a protective zone set up for a train after communication with its RBC (Radio Control Center) is interrupted. This zone prevents other trains from entering, ensuring the safety of the train whose communication is interrupted. Setting up a fault protection zone not only affects the operation of the train with the interrupted communication but also the operation of the trains preceding and following it. Therefore, after setting up a fault protection zone, it needs to be deactivated.

[0035] Research has revealed that errors or anomalies in clearing fault protection zones can pose safety hazards to trains experiencing communication disruptions, as well as to preceding and following trains. Therefore, the correctness of fault protection zone clearance directly impacts the operational safety of trains within the fault protection zone. Based on this, this embodiment provides a technical solution for testing fault protection zone clearance to verify its correctness. This ensures accurate clearance of fault protection zones after train operation, guaranteeing safe train operation.

[0036] The technical solution for testing the removal of fault protection zones provided in this embodiment is as follows: Communication between the target train running on the target line and the radio block center is interrupted; it is detected whether the target fault protection zone set up by the radio block center for the target train on the target line due to communication interruption is marked by a target color light band on the CTC station map of the dispatching centralized system; if so, a target object for removing the fault protection zone is selected from the target train, the radio block center, and the dispatching centralized system; the target object is controlled to perform the corresponding action for removing the fault protection zone; it is detected whether the target color light band can disappear from the CTC station map based on the target object performing the corresponding action; if so, the test for removing the fault protection zone is determined to be passed.

[0037] Based on the above-described technical solution for testing the fault protection zone, this embodiment specifically provides a testing method and apparatus for fault protection zone removal. The testing method and apparatus for fault protection zone removal provided in this embodiment will be described in detail below.

[0038] This application provides a test method for disabling fault protection zones, such as... Figure 1 As shown, the test method for removing the fault protection zone provided in this embodiment mainly includes the following steps 101 to 106:

[0039] 101. Control the interruption of communication between the target train running on the target line and the radio block center.

[0040] The fault protection zone removal test method provided in this embodiment can be applied to the following two scenarios: First, it is used for designated trains that have not yet been put into operation on designated lines to test in advance whether the fault protection zone can be correctly removed through the interaction between the designated train, the RBC on the designated line, and the centralized traffic control (CTC) system. Second, it is used for designated trains that have already been put into operation on designated lines to test whether the fault protection zone can be continuously and correctly removed through the interaction between the designated train, the RBC on the designated line, and the centralized traffic control (CTC) system.

[0041] Once it is determined that a fault protection zone removal test is needed, a target line and a target train are selected for testing. In this embodiment, the target line and target train can exist in two forms: First, the target line and target train are simulated lines and trains within a simulation system. In this case, the fault protection zone removal test does not require real trains and lines and can be completed through the simulation system, resulting in lower testing costs. Second, the target line and target train are real lines and trains in the real world. In this case, the fault protection zone removal test requires real trains running on real lines. Although the testing cost is higher, the test results are more realistic and accurate because the fault protection zone removal test is conducted in a real scenario. The choice between these two forms can be flexibly selected based on specific testing needs. If necessary, the first type of test (simulated lines and trains) can be used first, followed by the second type (real lines and trains). Finally, the results of the two tests can be combined to determine the final fault protection zone removal test result, thereby improving the accuracy of the test.

[0042] After determining the target line and target train, the target train is controlled to run on the target line. Then, communication between the target train running on the target line and the radio block center is interrupted. This causes the radio block center to set up a target fault protection zone on the target line for the target train due to the communication interruption, and a fault protection zone clearance test is performed based on the target fault protection zone. The specific process of the radio block center setting up the target fault protection zone may include the following steps: determining the tail protection position of the target train when communication with the target train is interrupted (the tail protection position is the position located behind the rear of the train and at a set distance from the rear of the train, which is used to prevent rear-end collisions with the target train); determining the latest train operation permit issued to the target train before the communication interruption, and determining the destination position corresponding to the train operation permit; setting the area from the tail protection position to the destination position as the target fault protection zone, so as to prevent other trains from colliding with the target train through the fault protection zone.

[0043] 102. Check whether the target fault protection zone set up by the radio block center for the target train on the target line by the target color light band on the CTC station map of the detection dispatching centralized system due to communication interruption; if yes, proceed to step 103; if no, proceed to step 106.

[0044] After setting up the target fault protection zone in the radio block center, the centralized dispatching system will mark the target fault protection zone with a target color light strip on the CTC station map to facilitate train dispatching. The specific process of the centralized dispatching system marking the target fault protection zone with a target color light strip on the CTC station map is as follows: determine the block section involved in the target fault protection zone, and mark the determined block section with the target color light strip. The specific color of the target color light strip can be flexibly selected based on business needs; this embodiment does not limit this. For example, the target color light strip is a pink light strip.

[0045] If the target fault protection zone set by the radio block center for the target train on the target line is marked by the target color light band on the CTC station map of the dispatching centralized system due to communication interruption, it means that the dispatching centralized system accurately displays the target fault protection zone set by the radio block center. The target fault protection zone can be used for the fault protection zone removal test. Therefore, step 103 can be continued to carry out the subsequent fault protection zone removal test.

[0046] If the target fault protection zone set by the radio block center for the target train on the target line is not marked by the target color light band on the CTC station map of the centralized dispatching system due to communication interruption, it indicates that there is an anomaly in the interaction between the radio block center and the centralized dispatching system regarding the target fault protection zone. The centralized dispatching system has failed to accurately display the target fault protection zone set by the radio block center. At this time, there is no fault protection zone available for the fault protection zone cancellation test, so step 106 is executed. A test failure prompt can also be issued to allow operational personnel to troubleshoot the anomaly based on the prompt.

[0047] 103. Select the target objects from the target train, the radio block center, and the centralized dispatching system to remove the fault protection zone.

[0048] The removal of a fault protection zone can be achieved by controlling at least one of the target train, the radio block center, and the centralized dispatching system to perform corresponding actions for removing the fault protection zone. Therefore, to more effectively remove fault protection zones, target objects for removing fault protection zones can be selected from the target train, the radio block center, and the centralized dispatching system. The target object can be selected from at least one of the target train, the radio block center, and the centralized dispatching system based on specific services; this embodiment does not limit this selection.

[0049] 104. Control the target object to perform the corresponding action to remove the fault protection zone, and detect whether the target color light band can disappear from the CTC site map based on the target object to perform the corresponding action; if it can, proceed to step 105; if it cannot, proceed to step 106.

[0050] The specific implementation of controlling the target object to perform the corresponding action to remove the fault protection zone and detecting whether the target color light band can disappear from the CTC site map based on the target object's corresponding action depends on the target object and the action. Based on this, the specific implementation of step 104 can include the following four methods:

[0051] The first type, if the target object includes the target train, and the specific process of controlling the target object to perform the corresponding action to clear the fault protection zone may include the following steps: controlling the target train to continue running forward along the target line in visual driving mode until it reaches the track in the station ahead.

[0052] The target object includes the target train. The target fault protection zone is disengaged by controlling this single target train. Specifically, the train driver presses a dedicated button to switch the train to visual operation mode. In visual operation mode, the driver is responsible for checking the track clearance and controlling the target train to continue moving forward along the target line until it safely stops on the track at the next station. This ensures the target train is no longer within the target fault protection zone and no longer poses a threat to following or preceding trains; the target fault protection zone can then be disengaged.

[0053] Based on this, the specific process of detecting whether the target color light band can disappear from the CTC site map by performing the corresponding action based on the target object can include the following steps 104A to 104C:

[0054] 104A. Detect whether the portion of the target color light strip located behind the tail protection position of the target train disappears from the CTC station map as the target train moves forward, and whether the target color light strip completely disappears from the CTC station map when the target train reaches the track in the station ahead.

[0055] If, as the target train moves forward, the portion of the target color light strip located after the tail protection position of the target train disappears from the CTC station diagram, it indicates that the portion of the target fault protection zone that the target train has already passed through is successfully cleared in real time as the target train gradually leaves the target fault protection zone. If the target color light strip completely disappears from the CTC station diagram when the target train reaches the track of the next station, it indicates that the target fault protection zone has been successfully cleared after the target train enters the safe zone. Therefore, to comprehensively test whether the fault protection zone can be correctly cleared, it is necessary to detect whether the portion of the target color light strip located after the tail protection position of the target train disappears from the CTC station diagram as the target train moves forward, and whether the target color light strip completely disappears from the CTC station diagram when the target train reaches the track of the next station.

[0056] 104B. If the portion of the target train located behind the tail protection position can disappear from the CTC station map in real time, and the target color light band disappears completely from the CTC station map when the target train runs to the track in the station ahead, then the target color light band can be detected to disappear from the CTC station map by performing the corresponding action based on the target object.

[0057] If the portion of the target train located after the tail protection position can disappear from the CTC station map, and the target color light band disappears completely from the CTC station map when the target train reaches the track in the station ahead, it indicates that the target fault protection zone has been correctly released regardless of whether the target train leaves the target fault zone or reaches the safe track. Furthermore, there are no errors or abnormalities in the process of releasing the fault protection zone. Therefore, it is detected that the target color light band can perform the corresponding action based on the target object and disappear from the CTC station map.

[0058] 104C. If the portion of the target train located after the tail protection position cannot disappear from the CTC station map, and / or, when the target train runs to the track in the station ahead, the target color light band does not completely disappear from the CTC station map, then it is detected that the target color light band cannot perform the corresponding action based on the target object to disappear from the CTC station map.

[0059] If the portion of the target train located after its tail protection position fails to disappear from the CTC station diagram, it indicates that the target fault protection zone cannot be correctly cleared during the process of the target train leaving the target fault protection zone, and an error or anomaly occurred during the clearance process. If the target color light band does not completely disappear from the CTC station diagram when the target train reaches the track of the next station, it indicates that the target fault protection zone cannot be correctly cleared after the target train reaches the safe track, and an error or anomaly occurred during the clearance process. Therefore, if the portion of the target train located after its tail protection position fails to disappear from the CTC station diagram, and / or if the target color light band does not completely disappear from the CTC station diagram when the target train reaches the track of the next station, it is detected that the target color light band cannot perform the corresponding action to disappear from the CTC station diagram based on the target object.

[0060] The second approach, if the target object includes the target train and the radio block center, and the specific process of controlling the target object to perform the corresponding actions to clear the fault protection zone may include the following steps: controlling the target train to stop at the position where communication was interrupted, and controlling the target train to restore communication with the radio block center.

[0061] Maintaining the target train at its position at the time of the communication interruption and controlling the restoration of communication between the target train and the radio block center ensures that the target train does not blindly move before communication is restored, but waits in place for communication to be restored, thereby reducing the possibility of accidents. When communication is restored, the target train can send its real-time location to the radio block center. This allows the radio block center to combine data such as ground track conditions, forward signals, and the target train's real-time location to calculate and issue a safe operating permit to the target train. This ensures the target train once again has a safe operating permit and can continue operating safely, thus releasing the target fault protection zone.

[0062] Based on this, the specific process of detecting whether the target color light band can disappear from the CTC site map by performing the corresponding action based on the target object can include the following steps 104D to 104F:

[0063] 104D. When the target train and the radio block center resume communication, check whether the target color light band disappears completely from the CTC station map.

[0064] If the target train and the radio block center resume communication and the target color light band disappears completely from the CTC station map, it indicates that the radio block center can continue to issue real-time departure permits to the target train, the target train is operating safely, and the target fault protection zone has been successfully removed. Therefore, it is necessary to detect whether the target color light band disappears completely from the CTC station map when the target train and the radio block center resume communication.

[0065] 104E. If the target color light band disappears completely from the CTC site map, then the target color light band is detected to be able to perform the corresponding action based on the target object to disappear from the CTC site map.

[0066] If the target color light band disappears completely from the CTC site map, it means that the target fault protection zone has been successfully removed. Therefore, the target color light band can be detected to disappear from the CTC site map by performing corresponding actions based on the target object.

[0067] 104F. If the target color light band does not completely disappear from the CTC site map, it is detected that the target color light band cannot perform the corresponding action based on the target object to disappear from the CTC site map.

[0068] If the target color light band does not completely disappear from the CTC site map, it means that the target fault protection zone has not been successfully removed. An error or anomaly occurred during the removal of the fault protection zone, and therefore the target color light band cannot perform the corresponding action based on the target object to disappear from the CTC site map.

[0069] In some embodiments, further considering that after the target train loses communication with the radio block center, the endpoint position of the train permission displayed in the target train's onboard human-machine interface (DMI) will change to the position of the target train at the time of the communication interruption, after step 104D detects that the target color light band can perform the corresponding action based on the target object and disappear from the CTC station map, the test method for clearing the fault protection zone provided in this embodiment may further include the following steps: determining whether the endpoint position of the train permission displayed in the target train's onboard human-machine interface (DMI) has recovered to the endpoint position of the train permission used when the communication was interrupted; if yes, then step 105 is executed to determine that the test for clearing the fault protection zone has passed; if no, then step 106 is executed to determine that the test for clearing the fault protection zone has failed.

[0070] After step 104D detects that the target color light band can perform corresponding actions based on the target object and disappear from the CTC station map, it indicates that the target fault protection zone has been successfully removed. For the target train to operate, the endpoint position of the train operation permit displayed in the onboard human-machine interface (DMI) must be restored to the endpoint position of the train operation permit used when communication was interrupted; otherwise, the normal operation of the target train will be affected. Therefore, it is necessary to determine whether the endpoint position of the train operation permit displayed in the target train's onboard human-machine interface (DMI) has been restored to the endpoint position of the train operation permit used when communication was interrupted.

[0071] If the endpoint of the train's driving permission displayed in the target train's onboard human-machine interface (DMI) is determined to have returned to the endpoint of the driving permission used when the communication was interrupted, it indicates normal operation. Therefore, step 105 is executed to confirm that the test to clear the fault protection zone has passed. If the endpoint of the train's driving permission displayed in the target train's onboard human-machine interface (DMI) has not returned to the endpoint of the driving permission used when the communication was interrupted, it indicates abnormal operation. Therefore, step 106 is executed to confirm that the test to clear the fault protection zone has failed.

[0072] The third approach, if the target object includes the target train and the radio block center, and the specific process of controlling the target object to perform the corresponding action to clear the fault protection zone, may include the following steps: controlling the target train to continue running forward along the target line in backup mode until it stops after reaching the designated block section ahead; after the target train stops, controlling the target train to restore communication with the radio block center.

[0073] The train driver can switch the train to backup mode by pressing a dedicated button. In backup mode, relying on operational rules and manual intervention, the train continues to run along the target line until it reaches and stops at a designated block section. The designated block section can be one that reduces the risk of collision with the target train, such as a block section where the distance to the following train is not less than a distance threshold. After the target train stops at the designated block section, communication between the target train and the radio block center is restored. This not only keeps the target train away from collision risks but also allows it to send its real-time location to the radio block center. The radio block center can then combine data such as ground track conditions, forward signals, and the target train's real-time location to calculate and issue a safe operating permit to the target train. This ensures the target train once again has a safe operating permit and can continue operating safely, thus deactivating the target fault protection zone.

[0074] Based on this, the specific process of detecting whether the target color light band can disappear from the CTC site map by performing corresponding actions based on the target object can include the following steps 104G to 104K:

[0075] 104G: During the process of the target train moving forward and stopping at the designated block section ahead, check whether the target color light band disappears completely or partially from the CTC station map.

[0076] If the target train disappears entirely or partially from the CTC station map during its forward movement and when it stops at the designated block section ahead, it indicates that the target fault protection zone has been mistakenly removed. At this point, the target train is still within the target fault protection zone, increasing the likelihood of a collision with other trains. Therefore, it is necessary to detect whether the target color light band disappears entirely or partially from the CTC station map during the target train's forward movement and when it stops at the designated block section ahead.

[0077] 104H. If the target color light band is detected to disappear completely or partially from the CTC site map, then the target color light band cannot disappear from the CTC site map by performing the corresponding action based on the target object.

[0078] If the target color light band is detected to disappear completely or partially from the CTC site map, it means that the control target object cannot correctly perform the corresponding action to remove the fault protection zone. Therefore, the target color light band cannot be detected to disappear from the CTC site map based on the target object performing the corresponding action.

[0079] 104I. If the target color light band is not completely or partially removed from the CTC station map, the target train and the radio block center will resume communication to check whether the target color light band has completely disappeared from the CTC station map.

[0080] If it is detected that the target color light band has not disappeared completely or partially from the CTC station map, it means that the target object is controlled to perform the corresponding action to remove the fault protection zone. It is highly likely that the fault protection zone can be removed correctly. Therefore, continue to detect whether the target train and the radio block center have resumed communication and whether the target color light band has disappeared completely from the CTC station map.

[0081] 104J. If the target color light band disappears completely from the CTC station map when the target train and the radio block center resume communication, then the target color light band can perform the corresponding action based on the target object to disappear from the CTC station map.

[0082] If, upon detection that the target train and the radio block center have resumed communication, the target color light band completely disappears from the CTC station map, it indicates that the radio block center can continue to issue real-time departure permits to the target train, the target train is operating safely, and the target fault protection zone has been successfully removed. Therefore, detecting the disappearance of the target color light band from the CTC station map is based on the corresponding action performed on the target object.

[0083] 104K. If the target color light band does not completely disappear from the CTC station map when the target train and the radio block center resume communication, then the target color light band cannot perform the corresponding action based on the target object to disappear from the CTC station map.

[0084] If, upon detection that the target train and the radio block center have resumed communication, the target color light band has not completely disappeared from the CTC station map, it indicates that the radio block center has not successfully removed the target fault protection zone. Therefore, the target color light band cannot disappear from the CTC station map based on the corresponding action performed on the target object.

[0085] Fourthly, if the target object includes the target train, and the specific process of controlling the target object to perform the corresponding action to remove the fault protection zone may include the following steps: controlling the target train to stop at the position when communication is interrupted; in the operation interface of the dispatching centralized system, along the running direction of the target train, sequentially performing the removal of the protection zone operation on the block sections involved in the target fault protection zone.

[0086] Maintaining the target train at its position when communication was interrupted ensures it doesn't blindly move until communication with the radio block center is restored, thus reducing the possibility of accidents. Furthermore, since the centralized dispatching system is for dispatchers, they can view the operation status of all trains within its service area on the CTC station map. After confirming there are no other trains affecting the safe operation of the target train within the target fault protection zone, the dispatchers can, through the centralized dispatching system's interface, sequentially de-protect the block sections involved in the target fault protection zone along the target train's direction of travel, thereby de-protecting the target fault protection zone.

[0087] For example, such as Figure 2 As shown, Figure 2 Line segment AB in the diagram represents the target color light band, which marks the target fault protection zone corresponding to target train G001. The target train is traveling forward in direction LL. In the operation interface of the centralized dispatching system, the protection zone is released sequentially for the block sections ab, bc, cd, and de involved in the target fault protection zone, along the direction of travel of the target train.

[0088] Based on this, the specific process of detecting whether the target color light band can disappear from the CTC site map by performing the corresponding action based on the target object can include the following steps 104L to 104O:

[0089] 104L. After performing the unprotection operation on a block section involved in each target fault protection zone, check whether the part of the target color light band corresponding to the block section disappears from the CTC station map. If it disappears, continue to perform the unprotection operation on the next block section. If it does not disappear, it is detected that the target color light band cannot perform the corresponding action based on the target object and disappear from the CTC station map.

[0090] For a block section involved in the target fault protection zone, if the target color light band and the part corresponding to the block section disappear from the CTC station map after the deprotection operation is performed on the block section, then the fault protection of the block section in the target fault protection zone has been successfully deprotected. Therefore, the deprotection operation can continue to be performed on the next block section until the deprotection operation is performed on all block sections in the target fault protection zone.

[0091] If, after the block section involved in the target fault protection zone is released, the part of the target color light band corresponding to the block section does not disappear from the CTC station map, it indicates that there is an abnormality in the release of the target fault protection zone. Therefore, it is detected that the target color light band cannot perform the corresponding action based on the target object and disappear from the CTC station map.

[0092] 104M. If all block sections involved in the target fault protection zone have undergone the protection zone release operation, check whether the target color light band has completely disappeared from the CTC station map.

[0093] If the target fault protection zone is successfully removed, the target color light band will inevitably disappear completely from the CTC site map. Therefore, it is necessary to check whether the target color light band has disappeared completely from the CTC site map.

[0094] 104N. If the target color light band is detected to have completely disappeared from the CTC site map, then the target color light band can be detected to have disappeared from the CTC site map by performing the corresponding action based on the target object.

[0095] If the target color light band is detected to have completely disappeared from the CTC site map, it means that the target fault protection zone has been successfully removed. Therefore, the detection of the target color light band can be based on the target object to perform the corresponding action and disappear from the CTC site map.

[0096] 104O. If the target color light band is not completely eliminated from the CTC site map, then the target color light band cannot be eliminated from the CTC site map by performing the corresponding action based on the target object.

[0097] If the target color light band is not completely removed from the CTC site map, it means that the target fault protection zone has not been successfully removed. The process of removing the fault protection zone has encountered an abnormality or error. Therefore, the target color light band cannot perform the corresponding action based on the target object to disappear from the CTC site map.

[0098] The above four methods can be used individually or in combination of at least two. This embodiment does not limit this and allows for flexible selection based on business needs. For example, when used in combination, the order in which the four target objects are tested to remove the fault protection zone can be set. Then, the fault protection zone is tested sequentially based on the target objects. Finally, the final test result is determined based on the test results of the four target objects.

[0099] 105. The test to remove the fault protection zone has been passed.

[0100] If the target color light band can be detected to disappear from the CTC site map by performing the corresponding action based on the target object, it means that the fault protection zone can be successfully and correctly removed, and no abnormalities or errors occurred during the test. Therefore, the test to remove the fault protection zone is confirmed to have passed.

[0101] 106. The test to remove the fault protection zone failed.

[0102] If the target color light band cannot disappear from the CTC site map based on the target object, it means that the fault protection zone cannot be removed smoothly and correctly, and an abnormality or error occurred during the test. Therefore, it is determined that the test to remove the fault protection zone has failed. At this time, a prompt can be issued so that business personnel can handle the abnormality based on the prompt.

[0103] The fault protection zone removal test method provided in this application involves controlling the communication between the target train running on the target line and the radio block center to be interrupted when testing the fault protection zone removal. The method detects whether the target fault protection zone set up by the radio block center for the target train on the target line due to the communication interruption is marked by a target color light band on the CTC station map of the centralized dispatching system. If the target fault protection zone is detected by the target color light band, a target object for removing the fault protection zone is selected from the target train, the radio block center, and the centralized dispatching system, and the target object is controlled to perform the corresponding action for removing the fault protection zone. Then, it is detected whether the target color light band can disappear from the CTC station map based on the target object performing the corresponding action. If the target color light band can disappear from the CTC station map based on the target object performing the corresponding action, the fault protection zone removal test is considered passed. As can be seen, the solution provided in this application selects a target object for clearing the fault protection zone from the target train, the radio block center, and the centralized dispatching system, and controls the target object to perform corresponding actions for clearing the fault protection zone. This tests the clearing of the fault protection zone to determine whether it can be correctly cleared. Thus, after the train is put into operation, the fault protection zone can be accurately cleared, thereby ensuring the safe operation of the train.

[0104] In some embodiments of this application, considering that after communication between the target train and the radio block center is interrupted, if the destination position displayed in the target train's onboard human-machine interface (DMI) is still the interruption position of the train operation permit used when communication was interrupted, the train driver may drive based on the displayed destination position, which may lead to an accident of the target train. Based on this, the test method for removing the fault protection zone provided in this embodiment may further include the following steps: After step 102, if it is detected that the target fault protection zone set by the radio block center for the target train on the target line due to communication interruption is marked by a target color light strip on the CTC station map of the dispatching centralized system, then it is detected whether the destination position of the train operation permit displayed on the target train's onboard human-machine interface (DMI) of the target train has changed to the position of the head of the target train; if yes, then step 103 is continued to select the target object for removing the fault protection zone from the target train, the radio block center, and the dispatching centralized system; if no, then step 106 is executed to determine that the test for removing the fault protection zone has failed.

[0105] If the target train's driving permission endpoint position displayed on the onboard human-machine interface (DMI) of the target train is detected to change to the position of the front of the target train, it means that the train driver can drive based on the changed position, thereby avoiding an accident to the target train. Therefore, step 103 is executed to continue the test of removing the fault protection zone.

[0106] If the target train's driving permission endpoint position displayed on the DMI (Device Management Interface) of the target train has not changed to the position of the train's front end, it indicates that the position displayed on the DMI may cause problems with the fault protection zone removal. Therefore, the test to remove the fault protection zone has failed.

[0107] In some embodiments of this application, the following example, taking a target train as an example, illustrates the test method for removing the fault protection zone provided in this embodiment. The method may include the following steps A1 to A12:

[0108] A1. Add the target train within station 1. The target train is successfully registered. Set the target train's running direction to downhill and run towards station 2.

[0109] A2. Control the target train to operate in full mode on the target line.

[0110] A3. After the target train operates in full mode in the target block section on the target line, the communication between the target train and the radio block center is interrupted.

[0111] A4. Check whether the target fault protection zone set up by the radio block center on the target line for the target train due to communication interruption is marked by the target color light strip on the CTC station map of the detection dispatching centralized system, and whether the destination position of the target train's driving permission displayed on the DMI of the target train has changed to the position of the head of the target train.

[0112] A5. If the target fault protection zone is marked by the target color light strip and changes to the position of the front of the train, then control the target train to switch to visual driving mode on the on-board human-machine interface (DMI).

[0113] A6. Control the target train to continue moving forward along the target line in visual driving mode.

[0114] A7. Detect whether the portion of the target color light band located behind the tail protection position of the target train disappears from the CTC station map as the target train moves forward.

[0115] A8. If A7 is detected as missing, the target train will continue to run along the target line in visual driving mode until it reaches the track in the next station 2, and then A10 will continue to be executed.

[0116] A9. If A7 detects that the fault has not disappeared, it is determined that the test to remove the fault protection zone has failed, and the current process ends.

[0117] A10. When the target train runs to the track in the station 2 ahead, check whether the target color light band disappears completely from the CTC station map.

[0118] A11. If A10 detects that all fault protection zones have disappeared, then the test to remove the fault protection zone has passed.

[0119] A12. If A10 detects that not all faults have disappeared, then the test to remove the fault protection zone has failed.

[0120] In some embodiments of this application, the following example illustrates the test method for removing the fault protection zone provided in this embodiment, taking the target object including the target train and the radio block center as an example. The method may include the following steps B1 to B8:

[0122] B2. Control the target train to operate in full mode on the target line.

[0123] B3. After the target train operates in full mode in the target block section on the target line, the communication between the target train and the radio block center is interrupted.

[0124] B4. Check whether the target fault protection zone set up by the radio block center on the target line for the target train due to communication interruption is marked by the target color light strip on the CTC station map of the detection dispatching centralized system, and whether the destination position of the target train's driving permission displayed on the DMI of the target train has changed to the position of the head of the target train.

[0125] B5. If the target fault protection zone is marked by the target color light strip and changes to the position of the train head, then control the target train to stop at the position when communication was interrupted, and control the target train to restore communication with the radio block center.

[0126] B6. When the target train and the radio block center resume communication, check whether the target color light band disappears completely from the CTC station map, and whether the end position of the train permission displayed in the target train's onboard human-machine interface (DMI) is restored to the end position of the train permission used when the communication was interrupted.

[0127] B7. If B6 detects yes, then the test to remove the fault protection zone has passed.

[0128] B8. If B6 detects no, then the test to remove the fault protection zone has failed.

[0129] In some embodiments of this application, the following example illustrates the test method for removing the fault protection zone provided in this embodiment, taking the target object including the target train and the radio block center as an example. The method may include the following steps C1 to C12:

[0130] C1. Add the target train within station 1. The target train is successfully registered. Set the target train's running direction to downhill and run towards station 2.

[0131] C2. Control the target train to operate in full mode on the target line.

[0132] C3. After the target train operates in full mode in the target block section on the target line, the communication between the target train and the radio block center is interrupted.

[0134] C5. If the target fault protection zone is marked by the target color light strip and changes to the position of the front of the train, then control the target train to switch to backup mode on the on-board human-machine interface (DMI).

[0135] C6. Control the target train to continue running along the target line in backup mode.

[0136] C7. Detect whether the target color light band disappears as the target train moves forward.

[0137] C8. If C7 detects that the target color light band has not disappeared, then continue to control the target train to continue running forward along the target line in backup mode until it stops at the designated block section ahead. After the target train stops, control the target train to restore communication with the radio block center and continue to execute C10.

[0138] C9. If C7 detects that the target color light band has disappeared, it is determined that the test to remove the fault protection zone has failed, and the current process ends.

[0142] In some embodiments of this application, the following example, taking a target object including a target train and a centralized dispatching system, illustrates the testing method for removing the fault protection zone provided in this embodiment. This method may include the following steps D1 to D8:

[0143] D1. Add the target train within station 1. The target train is successfully registered. Set the target train's running direction to downhill and run towards station 2.

[0144] D2. Control the target train to operate in full mode on the target line.

[0145] D3. After the target train operates in full mode in the target block section on the target line, communication between the target train and the radio block center is interrupted.

[0146] D4. Check whether the target fault protection zone set up by the radio block center on the target line for the target train due to communication interruption is marked by the target color light strip on the CTC station map of the detection dispatching centralized system, and whether the destination position of the target train's driving permission displayed on the DMI of the target train has changed to the position of the head of the target train.

[0147] D5. If the target fault protection zone is marked by the target color light strip and the position of the train head changes, then control the target train to stop at the position where communication was interrupted. In the operation interface of the dispatching centralized system, along the running direction of the target train, the protection zone removal operation is performed sequentially on the block sections involved in the target fault protection zone. After each block section involved in the target fault protection zone is removed, it is checked whether the part corresponding to the target color light strip and the block section disappears from the CTC station map. If it disappears, the protection zone removal operation is continued for the next block section. If it does not disappear, the test for removing the fault protection zone is determined to have failed.

[0148] D6. If all block sections involved in the target fault protection zone have undergone the protection zone release operation, check whether the target color light band has completely disappeared from the CTC station map.

[0149] D7. If D6 detects that all faults have disappeared, then the test to remove the fault protection zone has passed.

[0150] D8. If D6 detects that not all faults have disappeared, then the test to remove the fault protection zone has failed.

[0151] Furthermore, one embodiment of this application also provides a testing apparatus for disabling fault protection zones, such as... Figure 3As shown, the test apparatus for clearing the fault protection zone provided in this embodiment may include:

[0152] The first control module 21 is used to control the interruption of communication between the target train running on the target line and the radio block center.

[0153] The first detection module 22 is used to detect whether the target fault protection zone set up by the radio block center for the target train on the target line by the target color light band in the CTC station map of the dispatching centralized system is marked by the target color light band; if so, the selection module 23 is triggered to select the target object for removing the fault protection zone from the target train, the radio block center and the dispatching centralized system.

[0154] The second control module 24 is used to control the target object to perform corresponding actions to remove the fault protection zone;

[0155] The second detection module 25 is used to detect whether the target color light band can disappear from the CTC station map by performing the corresponding action based on the target object; if it can, the determination module 26 is triggered to determine that the test to remove the fault protection zone has passed.

[0156] The fault protection zone removal testing device provided in this application embodiment, when testing the fault protection zone removal, controls the communication between the target train running on the target line and the radio block center to be interrupted. It detects whether the target fault protection zone set up by the radio block center for the target train on the target line due to the communication interruption is marked by a target color light band on the CTC station map of the centralized dispatching system. If the target fault protection zone is detected by the target color light band, a target object for removing the fault protection zone is selected from the target train, the radio block center, and the centralized dispatching system, and the target object is controlled to perform the corresponding action for removing the fault protection zone. Then, it detects whether the target color light band can disappear from the CTC station map based on the target object performing the corresponding action. If the target color light band can disappear from the CTC station map based on the target object performing the corresponding action, the fault protection zone removal test is determined to be passed. As can be seen, the solution provided in this application selects the target object for removing the fault protection zone from the target train, the radio block center, and the centralized dispatching system, and controls the target object to perform the corresponding actions for removing the fault protection zone, so as to test the removal of the fault protection zone and determine whether the fault protection zone can be correctly removed. In this way, after the train is put into operation, the fault protection zone can be accurately removed, thereby ensuring the safe operation of the train.

[0157] In some embodiments of this application, such as Figure 4 As shown, if the target object includes the target train, then the second control module 24 includes:

[0158] The first control unit 241 is used to control the target train to continue running forward along the target line in visual driving mode until it reaches the track in the station ahead.

[0159] Therefore, the second detection module 25 includes:

[0160] The first detection unit 251 is used to detect whether, as the target train moves forward, the portion of the target color light strip located after the tail protection position of the target train disappears from the CTC station diagram, and whether the target color light strip completely disappears from the CTC station diagram when the target train reaches the track of the next station. If the portion located after the tail protection position of the target train disappears from the CTC station diagram, and the target color light strip completely disappears from the CTC station diagram when the target train reaches the track of the next station, then it is detected that the target color light strip can perform the corresponding action based on the target object to disappear from the CTC station diagram. If the portion located after the tail protection position of the target train does not disappear from the CTC station diagram, and / or, the target color light strip does not completely disappear from the CTC station diagram when the target train reaches the track of the next station, then it is detected that the target color light strip cannot perform the corresponding action based on the target object to disappear from the CTC station diagram.

[0161] In some embodiments of this application, such as Figure 4 As shown, if the target object includes the target train and the radio block center, then the second control module 24 includes:

[0162] The second control unit 242 is used to control the target train to stop at the position when communication is interrupted, and to control the target train to resume communication with the radio block center;

[0163] Therefore, the second detection module 25 includes:

[0164] The second detection unit 252 is used to detect whether the target color light band disappears completely from the CTC station map when the target train and the radio block center resume communication; if it disappears, it is detected that the target color light band can perform the corresponding action based on the target object to disappear from the CTC station map; if it does not disappear, it is detected that the target color light band cannot perform the corresponding action based on the target object to disappear from the CTC station map.

[0165] In some embodiments of this application, such as Figure 4As shown, the second detection unit 252 is further configured to, after detecting that the target color light band can perform the corresponding action based on the target object and disappear from the CTC station map, determine whether the end position of the train operation permission displayed in the on-board human-machine interaction device (DMI) of the target train has been restored to the end position of the train operation permission used when the communication was interrupted; if yes, the determination module 26 is triggered to perform the step of determining whether the test to remove the fault protection zone has passed; if no, the determination module 26 is triggered to determine whether the test to remove the fault protection zone has failed.

[0166] In some embodiments of this application, such as Figure 4 As shown, if the target object includes the target train and the radio block center, then the second control module 24 includes:

[0167] The third control unit 243 is used to control the target train to continue running forward along the target line in backup mode until it stops after reaching the designated block section ahead; after the target train stops, it controls the target train to resume communication with the radio block center.

[0168] Therefore, the second detection module 25 includes:

[0169] The third detection unit 253 is used to detect whether the target color light band disappears completely or partially from the CTC station map during the process of the target train moving forward and stopping at the designated block section ahead; if so, it is detected that the target color light band cannot disappear from the CTC station map by performing the corresponding action based on the target object; if not, it is detected whether the target color light band disappears completely from the CTC station map when the target train and the radio block center resume communication; if it disappears, it is detected that the target color light band can disappear from the CTC station map by performing the corresponding action based on the target object; if it does not disappear, it is detected that the target color light band cannot disappear from the CTC station map by performing the corresponding action based on the target object.

[0170] In some embodiments of this application, such as Figure 4 As shown, if the target object includes the target train and the dispatching centralized system, then the second control module 24 includes:

[0171] The fourth control unit 244 is used to control the position of the target train when communication is interrupted; in the operation interface of the dispatching centralized system, the block sections involved in the target fault protection zone are sequentially released along the running direction of the target train.

[0172] Therefore, the second detection module 25 includes:

[0173] The fourth detection unit 254 is used to detect whether the portion of the target color light band corresponding to the block section disappears from the CTC station map after each block section involved in the target fault protection zone is released from protection. If it disappears, the release operation is performed on the next block section. If it does not disappear, it is detected that the target color light band cannot perform the corresponding action based on the target object to disappear from the CTC station map. If all block sections involved in the target fault protection zone are released from protection, it is detected whether the target color light band disappears completely from the CTC station map. If it disappears completely, it is detected that the target color light band can perform the corresponding action based on the target object to disappear from the CTC station map. If it does not disappear completely, it is detected that the target color light band cannot perform the corresponding action based on the target object to disappear from the CTC station map.

[0174] In some embodiments of this application, such as Figure 4 As shown, the first detection module 22 can also be used to detect, after detecting that the target fault protection zone set by the radio block center for the target train on the target line due to communication interruption by marking the target fault protection zone in the CTC station map of the dispatching centralized system with a target color light band, whether the destination position of the target train's driving permission displayed on the DMI of the target train has changed to the position of the head of the target train; if yes, then the step of selecting the target object for removing the fault protection zone from the target train, the radio block center and the dispatching centralized system is executed; if no, then the determination module 26 is triggered to determine that the test for removing the fault protection zone has failed.

[0175] In some embodiments of this application, such as Figure 4 As shown, the determination module 26 can also be used to determine that the test to remove the fault protection zone has failed if the first detection module 22 detects that the target color light band cannot perform the corresponding action based on the target object and disappear from the CTC station map.

[0176] In some embodiments of this application, the target color light band involved in the test device for clearing the fault protection zone provided in this embodiment is a pink light band.
