Description

Technical Field

[0001] The present application relates to the field of rail transit technology, and in particular to a method and system for flexibly organizing urban rail transit under test signal shielding interference. Background Art

[0002] Urban rail transit currently mainly uses a train operation control system based on vehicle-ground communication. Continuous communication between the vehicle and the ground is an important prerequisite for ensuring the normal operation of urban rail transit. When the signal system determines that there is a vehicle-ground communication failure, the onboard ATP (Automatic Train Protection) will trigger the train's emergency braking to ensure driving safety. To ensure the driving safety of the connecting train, the ground ATP will control the idle section between the connecting train and the tracked train. When the trains are tracking closely, the connecting train will be forced to perform emergency braking and unplanned stops in the section, which will have a significant impact on the normal operation organization of urban rail transit.

[0003] The vehicle-ground wireless communication of urban rail transit basically adopts a closed network, and a strict access mechanism is set up to prevent the intrusion of non-signal system equipment into the vehicle-ground network.

[0038] In order to make the technical solutions and advantages in the embodiments of the present application more clearly understood, the exemplary embodiments of the present application are further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than an exhaustive list of all the embodiments. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0039] In the process of implementing this application, the inventors found that the vehicle-to-ground wireless communication of urban rail transit basically adopts a closed network, and a strict access mechanism is set up to prevent the intrusion of non-signal system equipment into the vehicle-to-ground network. However, the blocking interference method adopted by the examination shielding equipment will still cause interruption and interference to the vehicle-to-ground wireless communication. At present, more and more urban rail transit is built on elevated lines. When the elevated lines are close to urban schools, the examination shielding equipment used by the school to organize examinations will interfere with the normal vehicle-to-ground wireless communication of urban rail transit.

[0040] In response to the above problems, the present application provides a flexible organization method and system for urban rail transit under test signal shielding interference, the method comprising: ATS sets one or more test interference area information; wherein, any test interference area information includes: the interference range and interference time of any interference area; ATS transmits the test interference area information to the ground ATP; the ground ATP calculates the mobile authorization including each interference area based on the test interference area information; wherein, any mobile authorization includes a single interference area, otherwise it retreats to the beginning of the interference area; only one train is allowed to pass through any interference area; the ground ATP sends the mobile authorization to the on-board ATP; when the train passes through the interference area, the on-board ATP on the train automatically maintains the mobile authorization operation, and the on-board ATP and the ground ATP on the train no longer monitor the wireless communication status between the train and the ground. According to the method provided in the present application, after the ATS sets the test interference area information, the ground ATP calculates the movement authorization according to the test interference area information, and any movement authorization includes a single interference area, otherwise it retreats to the beginning of the interference area to avoid the movement authorization distance being insufficient so that the passing train makes an unplanned stop in the interference area. When the train passes through the interference area, the on-board ATP on the train automatically maintains the movement authorization operation, and the on-board ATP and the ground ATP on the train no longer monitor the wireless communication status between the train and the ground, so that the on-board ATP does not trigger the emergency braking of the train due to the loss of train-ground communication, thereby avoiding the impact of signal shielding interference on the normal operation organization of urban rail transit.

[0041] See also Figure 1 This embodiment provides a flexible organization method for urban rail transit under test signal shielding interference, and the implementation process of the method is as follows:

[0042] 101. ATS (Automatic Train Supervision) sets one or more test interference area information.

[0043] The information of any test interference area includes: the interference range and interference time of any interference area.

[0044] The implementation process of step 101 is as follows:

[0045] 101-1, ATS obtains test disruption plan.

[0046] Among them, the examination interference plan includes the examination signal shielding interference time and interference range.

[0047] The exam disruption plan is determined based on the rail transit lines and the locations of schools along the lines, and is based on tests of exam times and locations.

[0048] like Figure 2 As shown, based on the rail transit lines and the locations of schools along the lines, the test determines the location and specific interference range of each school when interference is turned on, and then obtains the examination interference plan.

[0049] 101-2, ATS sets one or more test interference area information according to the test interference plan.

[0050] like Figure 3 As shown, ATS obtains the school's test plan in advance, combines the test plan and location, dynamically sets one or more test interference areas at a time, and then obtains information on one or more test interference areas. Figure 3 The action time is the test signal shielding interference time, and the test interference area is the interference range.

[0051] 102. ATS transmits the test interference area information to the ground ATP (Automatic Train Protection, the train's automatic protection system).

[0052] In addition, ATS will transmit the test interference area information to the on-board ATP.

[0053] For example, after the test interference area information is set successfully, the test interference area information will be transmitted to the ground ATP and the vehicle-mounted ATP.

[0054] 103. The ground ATP calculates the movement authorization including each interference area according to the test interference area information.

[0055] Among them, any movement authorization includes a single interference area, otherwise it retreats to the beginning of the interference area. Only one train is allowed to run through any interference area.

[0056] like Figure 4 As shown, only one train is allowed to pass through a single interference zone (i.e., any interference area), and the movement authorization calculated by the ground ATP includes the range of a single interference zone. Otherwise, it will retreat to the beginning of the interference zone to avoid the unplanned stop of the passing train in the interference zone due to insufficient movement authorization distance.

[0057] 104. The ground ATP sends the movement authorization to the vehicle ATP.

[0058] 105. When a train passes through an interference area, the onboard ATP on the train automatically maintains mobile authorization operation, and the onboard ATP on the train and the ground ATP no longer monitor the train-ground wireless communication status.

[0059] If there are multiple trains running in any interference area, the onboard ATP on the first train will automatically stop in any interference area before clearing any interference area and re-establishing communication with the ground ATP based on the movement authorization of any interference area, and the trains at the station will automatically trigger the train detention.

[0060] After the first train clears any interference area according to the movement authorization of any interference area and re-establishes communication with the ground ATP, the ground ATP extends the movement authorization of any interference area and allows subsequent trains to enter any interference area according to the movement authorization of any interference area.

[0061] When there is no other train between the platform where the train is located and any interference area, the train detention on the platform where the train is located will be automatically cancelled, allowing the train to enter any interference area.

[0062] like Figure 5 As shown, when a train passes through the interference area, the on-board ATP on it automatically maintains the movement authorization operation received previously, and the on-board ATP / ground ATP no longer monitors the train-ground wireless communication status, and the on-board ATP does not trigger the train's emergency braking due to the loss of train-ground communication.

[0063] If there are multiple trains running in any interference area, Figure 6 As shown, the onboard ATP on the first train T3 clears any interference area according to the movement authorization of any interference area before re-establishing communication with the ground ATP. The subsequent train T2 automatically stops in any interference area, and the in-station train T1 automatically links and triggers the train detention to reduce the occurrence of section stops.

[0064] When the preceding train (i.e. the first train T3) passes through any interference area, the onboard ATP re-establishes communication with the ground ATP, and the ground ATP extends the movement authorization to allow the subsequent train T2 to enter any interference area.

[0065] When there are no other trains on the platform where train T1 is located and in any interference area, the platform's train detention is automatically cancelled and train T1 is allowed to enter any interference area.

[0066] In addition, after the exam, the interference area setting can be cancelled manually or automatically based on the entered exam deadline.

[0067] The flexible organization method of urban rail transit under test signal shielding interference provided in this embodiment flexibly sets / cancels the interference operation area of ​​urban rail transit according to the time and area scope of the test plan, and solves the interference problem of test jammers on urban rail transit through automatic linkage processing of the train operation control system. Avoid emergency braking caused by vehicle-ground wireless communication failure, avoid the impact on operation organization caused by this, and ensure the normal operation of urban rail transit.

[0068] This embodiment provides a flexible organization method for urban rail transit under test signal shielding interference. After the ATS sets the test interference area information, the ground ATP calculates the movement authorization according to the test interference area information, and any movement authorization includes a single interference area, otherwise it retreats to the beginning of the interference area to avoid the movement authorization distance being insufficient so that the passing train makes an unplanned stop in the interference area. When the train passes through the interference area, the on-board ATP on the train automatically maintains the movement authorization operation, and the on-board ATP and the ground ATP on the train no longer monitor the wireless communication status between the train and the ground, so that the on-board ATP does not trigger the emergency braking of the train due to the loss of train-ground communication, thereby avoiding the impact of signal shielding interference on the normal operation organization of urban rail transit.

[0069] Based on the same inventive concept of the flexible organization method of urban rail transit under test signal shielding interference, this embodiment provides a flexible organization system of urban rail transit under test signal shielding interference, the system comprising: ATS, ground ATP and train. The train is equipped with an on-board ATP.

[0070] ATS is used for one or more test interference area information. The test interference area information is transmitted to the automatic protection system ATP of the ground train. Any test interference area information includes: the interference range and interference time of any interference area.

[0071] The ground ATP is used to calculate the movement authorization including each interference area according to the test interference area information. The movement authorization is sent to the on-board ATP. Among them, any movement authorization includes a single interference area, otherwise it retreats to the beginning of the interference area; only one train is allowed to run through any interference area.

[0072] When a train passes through an interference area, the onboard ATP on the train automatically maintains mobile authorization operation, and the onboard ATP on the train and the ground ATP no longer monitor the train-ground wireless communication status.

[0073] The ATS is used to obtain the test interference plan. The test interference plan includes the test signal shielding interference time and interference range. One or more test interference area information is set according to the test interference plan.

[0074] Among them, the examination interference plan is determined based on the rail transit lines and the locations of schools along the lines, and is tested based on the examination time and location.

[0075] Among them, the train is used for if there are multiple trains running in any interference area, if the train is the first train, the on-board ATP on it will clear any interference area according to the movement authorization of any interference area and re-establish communication with the ground ATP. If the train is a subsequent train, the on-board ATP on the first train will automatically stop in any interference area before clearing any interference area according to the movement authorization of any interference area and re-establishing communication with the ground ATP. If the train is an in-station train, the on-board ATP on the first train will automatically trigger the train detention before clearing any interference area according to the movement authorization of any interference area and re-establishing communication with the ground ATP.

[0076] Among them, ground ATP is also used to extend the movement authorization of any interference area after the first train clears any interference area according to the movement authorization of any interference area and re-establishes communication with the ground ATP, allowing subsequent trains to enter any interference area according to the movement authorization of any interference area.

[0077] Among them, ground ATP is also used to automatically cancel the detention of the platform where the train is located when there is no other train between the platform where the train is located and any interference area, allowing the train to enter any interference area.

[0078] The present application provides a flexible organization system for urban rail transit under test signal shielding interference, including: ATS, ground ATP and train, with on-board ATP installed on the train. After the ATS sets the test interference area information, the ground ATP calculates the movement authorization according to the test interference area information, and any movement authorization includes a single interference area, otherwise it retreats to the beginning of the interference area to avoid the movement authorization distance being insufficient so that the passing train makes an unplanned stop in the interference area. When the train passes through the interference area, the on-board ATP on the train automatically maintains the movement authorization operation, and the on-board ATP and ground ATP on the train no longer monitor the vehicle-ground wireless communication status, so that the on-board ATP does not trigger the emergency braking of the train due to the loss of vehicle-ground communication, thereby avoiding the impact of signal shielding interference on the normal operation organization of urban rail transit.
