The method includes: ATS sets one or more exam interference area information, and ATS transmits the exam interference area information to the ground ATP. The ground ATP calculates the movement authority according to the exam interference area information.

[0002] Currently, urban rail transit mainly adopts 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 a vehicle-ground communication failure, the on-board ATP (Automatic Train Protection) will trigger the emergency braking of the train to ensure traffic safety. To ensure the traffic safety of the following trains, the ground ATP will control the section where the following train and the tracked train are idle intervals. When the trains are tracked closely, it will cause the emergency braking and unscheduled parking of the following train in the section, which will have a greater impact on the normal operation organization of urban rail transit.

[0038] In order to make the technical solutions and advantages in the embodiments of this application clearer, the following further describes the exemplary embodiments of this application in detail with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, rather than an exhaustive list of all embodiments. It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other.

[0039] In the process of implementing this application, the inventor found that the vehicle-ground wireless communication in urban rail transit basically adopts a closed network, and a strict access mechanism is set to prevent non-signal system equipment from invading the vehicle-ground network. However, the blocking interference method adopted by the exam shielding device will still cause interruption interference to the vehicle-ground wireless communication. At present, more and more urban rail transit lines are built on elevated lines. When the elevated line is close to urban schools, the exam shielding devices enabled by schools during exams will interfere with the normal communication of the vehicle-ground wireless in urban rail transit.

[0040] In view of the above problems, this application provides a method and system for flexible organization of urban rail transit under exam signal shielding interference. The method includes: the ATS sets one or more exam interference area information; wherein, any exam interference area information includes: the interference range and interference time of any interference area; the ATS transmits the exam interference area information to the ground ATP; the ground ATP calculates the movement authorization including each interference area according to the exam interference area information; wherein, any movement authorization includes a single interference area, otherwise it retreats to the start end of the interference area; only one train is allowed to run through any interference area; the ground ATP sends the movement authorization to the on-board ATP; when the train passes through the interference area, the on-board ATP on the train automatically maintains the movement authorization to run, and the on-board ATP and the ground ATP on the train no longer monitor the vehicle-ground wireless communication status. After the method provided by this application sets the exam interference area information, the ground ATP calculates the movement authorization according to the exam interference area information, and any movement authorization includes a single interference area, otherwise it retreats to the start end of the interference area, avoiding the situation that the movement authorization distance is insufficient and causing the passing train to stop unexpectedly in the interference area. When the train passes through the interference area, the on-board ATP on the train automatically maintains the movement authorization to run, and the on-board ATP and the 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.

[0041] See Figure 1 , this embodiment provides a method for flexible organization of urban rail transit under exam signal shielding interference. The implementation process of this method is as follows:

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

[0043] Among them, any examination interference area information includes: the interference range and interference time of any interference area.

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

[0045] 101-1. The ATS obtains an examination interference plan.

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

[0047] The examination interference plan is determined by testing based on the rail transit line and the locations of schools along the line, the examination time, and the examination location.

[0048] As Figure 2 shown, according to the rail transit line and the locations of schools along the line, the location and specific interference range when interference is turned on for each school are tested to obtain the examination interference plan.

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

[0050] As Figure 3 shown, the ATS obtains the school examination plan in advance, combines the examination plan and location, and dynamically sets one or more examination interference areas at one time to obtain one or more examination interference area information. Figure 3 The action time in is the examination signal shielding interference time, and the examination interference area is the interference range.

[0051] 102. The ATS transmits the examination interference area information to the ground ATP (Automatic Train Protection).

[0052] In addition, the ATS also transmits the examination interference area information to the on-vehicle ATP.

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

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

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

[0056] As Figure 4 shown, only one train is allowed to run through a single interference area (i.e., any interference area). The movement authority calculated by the ground ATP includes the scope of a single interference area. Otherwise, it will retreat to the start of the interference area to avoid the situation that the movement authority distance is insufficient and the passing train makes an unscheduled stop in the interference area.

[0057] 104. The ground ATP sends the movement authority to the on-board ATP.

[0058] 105. When the train passes through the interference area, the on-board ATP on the train automatically maintains the operation of the movement authority, and the on-board ATP and the ground ATP on the train no longer monitor the status of the vehicle-ground wireless communication.

[0059] If there are multiple trains running in any interference area, before the on-board ATP on the leading train clears any interference area according to the movement authority of any interference area and re-establishes communication with the ground ATP, the subsequent trains will automatically stop in any interference area, and the in-station trains will automatically trigger the train detention in a linked manner.

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

[0061] When there are no other trains between the platform where the in-station train is located and any interference area, the train detention at the platform where the in-station train is located is automatically cancelled in a linked manner, and the in-station train is allowed to enter any interference area.

[0062] As Figure 5 shown, for the train running through the interference area, the on-board ATP on it automatically maintains the operation of the previously received movement authority. The on-board ATP / ground ATP no longer monitors the status of the vehicle-ground wireless communication, and the on-board ATP does not trigger the emergency braking of the train due to the loss of vehicle-ground communication.

[0063] If there are multiple trains running in any interference area, as Figure 6 shown, before the on-board ATP on the leading train T3 clears that any interference area according to the movement authority of any interference area and re-establishes communication with the ground ATP, the subsequent train T2 automatically stops in that any interference area, and the in-station train T1 automatically triggers the train detention in a linked manner to reduce the occurrence of in-section stops.

[0064] After the previous train (i.e., the leading train T3) runs through that any interference area and its on-board ATP re-establishes communication with the ground ATP, the ground ATP extends the movement authority to allow the subsequent train T2 to enter that any interference area.

[0065] When there are no other trains on the platform where the in-station train T1 is located and the any interference area, the train detention at the platform is automatically cancelled in a linked manner, and train T1 is allowed to enter the any interference area.

[0066] In addition, after the examination ends, the setting of the interference area can be cancelled manually or automatically based on the input examination end time.

[0067] The flexible organization method of urban rail transit under the interference of examination signal shielding provided by this embodiment flexibly sets / cancels the interference operation area of urban rail transit according to the time and area range of the examination plan, and solves the interference problem of the examination jammer to urban rail transit through the automatic linked processing of the train operation control system. It avoids the emergency braking caused by the vehicle-ground wireless communication failure, avoids the impact on the operation organization caused thereby, and ensures the normal operation of urban rail transit.

[0068] This embodiment provides a flexible organization method of urban rail transit under the interference of examination signal shielding. After the ATS sets the examination interference area information, the ground ATP calculates the movement authorization according to the examination interference area information, and any movement authorization includes a single interference area, otherwise it retreats to the start end of the interference area to avoid the unplanned stop of the passing train in the interference area due to insufficient movement authorization distance. 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 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.

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

[0070] Among them, the ATS is used for one or more examination interference area information. Transmit the examination interference area information to the automatic train protection system ATP of the ground train. Among them, any examination interference area information includes: the interference range and interference time of any interference area.

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

[0072] The train is used for when passing 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 vehicle-ground wireless communication status.

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

[0074] Among them, the exam interference plan is determined by testing based on the rail transit line and the locations of schools along the line, as well as the exam time and exam location.

[0075] Among them, for the train, if there are multiple trains running in any interference area, if the train is the leading train, the on-vehicle ATP on it clears any interference area according to the movement authorization of any interference area and re - establishes communication with the ground ATP. If the train is a following train, it automatically stops in any interference area before the on-vehicle ATP on the leading train clears any interference area according to the movement authorization of any interference area and re - establishes communication with the ground ATP. If the train is a train at a station, before the on-vehicle ATP on the leading train clears any interference area according to the movement authorization of any interference area and re - establishes communication with the ground ATP, it automatically triggers the train detention in a linked manner.

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

[0077] Among them, the ground ATP is also used to, when there are no other trains between the platform where the train at the station is located and any interference area, automatically cancel the train detention at the platform where the train at the station is located in a linked manner and allow the train at the station to enter any interference area.

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