Upon reaching the exit signal, the driver must confirm the train's initial position before onboard equipment can monitor its operation. This manual operation not only increases the driver's workload but is also prone to delays and safety hazards due to human error, compromising the operational efficiency and safety of freight trains.

[0024] Exemplary embodiments of the present disclosure will be described more fully hereinafter with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it is understood that the present disclosure can be embodied in various forms without being limited by 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 present disclosure to those skilled in the art.

[0025] Currently, in the existing freight railway system, after the train starts or completes the shunting operation in the station, the on-board device is usually in an undetermined state. The driver needs to manually input the information of the track where the train is located, and then drives the train out of the station according to the state of the signal machine, and observes the situation of the front route in real time to ensure that there is no obstacle. At the exit signal machine, the driver also needs to confirm the initial position of the train, and then the on-board device can monitor the train operation. Such manual operation not only increases the labor intensity of the driver, but also easily causes delay and safety hazards due to human factors, thereby affecting the operation efficiency and safety of the freight train. In addition, the freight railway hub station is complex, and the demand for automatic dispatching management is particularly urgent.

[0026] After research, the inventors found that an automated mechanism can be used to manage the departure of freight trains at freight railway hubs. That is, multiple train types are set according to the different train-ground wireless communication status and train position status reports, such as hidden trains, non-communication trains, communication trains, and visually authorized trains. Each train type is set with a light display state of on or off and a departure mode of moving block or inter-station block, so as to detect whether the departure route is open according to the different departure modes, and after determining that the departure route is open, the train is operated according to the corresponding departure strategy. In this way, the disadvantages of relying on the driver to manually input information are effectively eliminated, the labor intensity caused by manual operation is reduced, the possibility of operational errors is reduced, and it can better adapt to different types of trains and complex station environments, realize automatic switching between mobile block mode and fixed block mode, meet the departure requirements of different train types, reduce delays caused by human factors, improve departure frequency and transportation efficiency, and at the same time ensure the safe operation of the train, thereby significantly improving the operating efficiency and safety of freight railways.

[0027] Based on the above considerations, the embodiment of the present application provides a new freight departure management method of the train control system, which can improve the operating efficiency and safety of freight trains. The specific execution steps are as follows: Figure 1 As shown, including:

[0028] 101. Determine the train type of the target train based on the train-ground wireless communication status and the train position status report.

[0029] Among them, train types include hidden trains, non-communication trains, communication trains and visual authorization trains.

[0030] In this step, the onboard equipment (ATP) establishes a communication connection with the radio block center (RBC) via a vehicle-ground wireless communication network (such as LTE-M). The RBC receives the registration request from the ATP and performs the registration and authentication process to ensure secure and reliable communication. The ATP and RBC continuously monitor the communication status. If a communication timeout or disconnection is detected, the system automatically takes appropriate downgrade measures.

[0031] ATP initializes the positioning of the train track based on the departure information input by the driver (such as station number, track number and departure direction, etc.) and satellite positioning results. Specifically, if ATP succeeds in satellite positioning within the startup positioning time, it will perform a reverse search based on satellite positioning to identify the nearest transponder (LRBG) corresponding to the current position of the train, indicating that the train position is known. If ATP fails to locate the satellite within the startup positioning time, it means that the train position is unknown and a train position status report is sent to the RBC. The position status report includes three states: unknown train position, unknown train position and no departure information, unknown train position and departure information, and known train position and departure information.

[0032] If the ATP is not registered to the RBC, the communication between the ATP and the RBC cannot be established, and the ATP cannot send the train position status report to the RBC regularly, at this time the RBC sets the train type of the train as a hidden train, if the ATP is registered to the RBC and the train position status report is that the position is known and there is departure information, the RBC sets the train type of the train as a communication train, if the ATP is registered to the RBC but the train position status report is that the position is unknown and there is departure information, the RBC sets the train type of the train as a visual authorization train, if the ATP is registered to the RBC but the train position status report is that the position is unknown and there is no departure information, the RBC sets the train type of the train as a non-communication train.

[0033] Based on the above description, the specific process of determining the train type of the target train according to the train-ground wireless communication state and the train position status report needs to perform the following steps 101A to 101C:

[0034] 101A, detecting whether the target train and the corresponding wireless block center establish communication.

[0035] In this step, the on-board equipment (ATP) on the target train identifies the current station where the train is located through satellite positioning, obtains the RBC number of the station using the locally stored electronic map, and sends a registration request to the wireless block center (RBC) after obtaining the RBC IP address from the address query server. After the RBC receives the registration request, identity verification and security check are performed, if the verification is passed, a registration success response is sent to the ATP, and a communication connection is established at the same time, at this time if the communication is successfully established, step 101C is executed, otherwise if the communication fails to be established, step 101B is executed.

[0036] 101B, determining that the target train is a hidden train.

[0037] Since the ATP on the target train is not registered to the RBC at this time, that is, the communication with the RBC is not successfully established, it means that the train position cannot be determined, and is in an unknown position state. Therefore, it can be determined that the train type of the target train is a hidden train.

[0038] 101C, determining that the target train is a communication train if the train position status report is that the position is known and there is departure information, determining that the target train is a visual authorization train if the train position status report is that the position is unknown and there is departure information, and determining that the target train is a non-communication train if the train position status report is that the position is unknown and there is no departure information.

[0039] Since the ATP on the target train and the RBC have successfully established communication at this time, the ATP and the RBC will periodically exchange heartbeat packets, that is, the ATP will periodically send a train position status report to the RBC. The train position status report is generated by the ATP according to the driver input departure information (such as station number, track number and departure direction) and the satellite positioning result for the initialization positioning of the train track. The train position status report contains the following states: position unknown: the train position cannot be determined; position unknown and no departure information: the train position cannot be determined, and there is no departure information; position unknown and with departure information: the train position cannot be determined, but there is departure information; position known and with departure information: the train position has been determined, and there is departure information. Therefore, in this step, if it is position known and with departure information, it can be determined that the train type of the target train is a communication train, if it is position unknown and with departure information, it can be determined that the target train is a visual authorization train, and if it is position unknown and no departure information, it can be determined that the target train is a non-communication train.

[0040] 102. Determine the light display state and departure mode of the target train based on the train type.

[0041] Among them, the light display state includes light-off and light-on, and the departure mode includes block between stations and moving block.

[0042] For the light display state:

[0043] It should be noted that since the communication state of the hidden train is unreliable, the position and state thereof cannot be accurately grasped, and the light-on light display state can ensure that other trains and dispatchers can clearly see the signal, avoiding potential collision risks. The communication state of the communication train and the visual authorization train is good, and the position and state thereof can be monitored in real time, and the light-off light display state can reduce visual interference, thereby improving the clarity and reliability of the signal. Therefore, from the perspective of safety, the light-off and light-on light display states are pre-set, so as to adapt the light-on and light-off modes of the signal on the departure route of the train type to the train type after determining the train type.

[0044] For the departure mode:

[0045] It should be noted that, since the communication state of the communication train and the visual authorization train is good, the mobile block mode is adopted to more finely manage the spacing between trains, improve the departure frequency and transportation efficiency, and the hidden train adopts the block mode, although the departure frequency is low, but provides reliable guarantee in communication failure or other special circumstances, ensures the continuity and stability of transportation. Therefore, from the perspective of efficiency, the block mode and the mobile block mode are also pre-set as the departure mode, so as to detect the opening condition of the departure route of the train type after determining the train type, thereby ensuring safety while improving the departure efficiency of different train types.

[0046] In this step, the correspondence between different train types and the light display state and the departure mode can be pre-constructed, when the train type is determined, the corresponding light display state and departure mode are found through the correspondence, that is, if it is a communication train and a visual authorization train, the signal of the departure route is controlled to be off, and the mobile block mode is adopted, and if it is a hidden train, the signal of the departure route is controlled to be on, and the block mode is adopted.

[0047] It should be noted that the embodiment is usually applied to a freight railway hub station, and the freight railway hub station is complex, and different types of trains have different departure requirements. By flexibly selecting the light display state and the departure mode, not only the running efficiency and system reliability of the freight train are improved under the premise of ensuring safety, but also the different types of trains and complex station environment are better adapted, and reliable guarantee is provided in communication failure or other abnormal conditions.

[0048] 103、If the train type is a communication train or a visual authorization train, the signal of the departure route is controlled to be off, and whether the departure route is open is detected based on the opening condition of the mobile block, and after confirming that the departure route is open, the target train is controlled to execute the train operation according to the first departure strategy.

[0049] Among them, the first departure strategy is used to represent the switching strategy from the visual authorization mode to the full monitoring mode based on the position state of the communication train or the visual authorization train.

[0050] In this step, the radio block center (RBC) sends a signal control instruction to the train control and interlocking integrated device (TIS) according to the train type of the communication train or the visual authorization train, to control the signal of the departure route to be off. The TIS checks the opening conditions of the departure route according to the train type of the approaching signal of the RBC, including the departure direction, whether there is a hidden train in the section, etc. Specifically, the target section can be determined according to the departure direction of the target train, and whether there is any hidden train in the target section is determined based on the section axle state, the section track section state and the section train information corresponding to the target section. If not, it is determined that the departure route cannot be opened. That is, when the TIS confirms that the section axle state and the section track section state are all idle, or there is no train entering the target section that has not established communication, it is determined that there is no hidden train in the target section, and vice versa.

[0051] After confirming that the departure route can be opened, the TIS opens the departure signal and continues to monitor the state of the departure signal. Since at this time both the communication train and the visual authorization train are on the station track, in order to gradually confirm the safety status of the front line and ensure that the fully monitored mode is switched after confirming that there is no error, the communication train and the visual authorization train need to be turned into the visual authorization mode during the departure process. That is, at this time the RBC will send visual authorization information to the on-board equipment (ATP) on the target train to enter the visual authorization mode, but because the position of the communication train is known and the position of the visual authorization train is unknown, the visual authorization information of the communication train and the visual authorization train is different. When it is a communication train, the RBC takes the distance from the nearest transponder (LRBG) corresponding to the target train to the end of the departure route section as the visual authorization distance, and sends the visual authorization information to the ATP, and when it is a visual authorization train, the RBC takes the length of the departure route as the authorization distance, and sends the visual authorization information to the ATP. At this time, the ATP controls the target train to run in the target authorization mode according to the visual authorization information.

[0052] It should be noted that in actual application, a specific area is usually arranged before the exit signal on the track, which is used to confirm whether the front track is idle at the key position, so that the train can be turned into the full monitoring mode driving earlier. The specific area is the manual track idle confirmation area. Since the visual authorization end of the communication train is the end of the departure route, and its position is known, that is, it will pass through the manual track idle confirmation area or when the car is stationary after starting, its estimated front end position is in the manual track idle confirmation area. Therefore, after the RBC determines that the train enters the manual track idle confirmation area, it sends a track circuit idle confirmation request to the ATP. After the driver confirms that the track circuit is idle, the RBC sends driving permission information in the full monitoring mode to the ATP, so as to control the target train to change from the target authorization mode to the full monitoring mode driving. The visual authorization distance of the visual authorization train is the entire departure route, and the departure transponder on the departure route is usually arranged corresponding to the exit signal. That is, the visual authorization train can only change from the unknown position to the known position when passing through the departure transponder. At this time, the RBC automatically upgrades the train type of the target train from the visual authorization train to the communication train, and sends driving permission information in the full monitoring mode to the ATP.

[0053] Case one, based on the above description of controlling the target train to perform driving operation according to the first departure strategy for the communication train, the following steps 103A to 103D need to be performed:

[0054] 103A, if the train type is a communication train, the distance from the nearest transponder of the target train to the end section terminal of the departure route is taken as the visual authorization distance, and the target train is controlled to drive in the target authorization mode.

[0055] In this step, the RBC takes the distance from the LRBG to the end section terminal of the departure route as the visual authorization distance according to the LRBG of the target train and the position of the end section terminal of the departure route, and generates visual authorization information including authorization distance and transponder list to be passed through. The end section terminal refers to the last control point that needs to be confirmed in the departure route, that is, the reverse entry signal on the departure route. After the visual authorization information, the RBC sends the visual authorization information to the ATP, and the ATP controls the train to drive in the target authorization mode on the departure route according to the received visual authorization information. In the target authorization mode, the train drives at a lower speed to ensure that the driver can confirm the safety condition of the front line within the visual range. The ATP continuously monitors the position and speed of the train to ensure that the train drives safely within the visual authorization distance.

[0056] 103B, detecting whether the estimated front end of the target train is in the manual track idle confirmation area when the car is stationary after starting.

[0057] In this step, the RBC detects whether the estimated front end of the target train is in the artificial track idle confirmation area when it is started and not moving based on the estimated front end position of the target train obtained from the ATP and the position of the artificial track idle confirmation area pre-defined by the RBC. That is, the RBC will detect the track status in the artificial track idle confirmation area through the track circuit to confirm whether the front track is idle. If so, execute step 103C, otherwise execute step 103D.

[0058] 103C. After the track circuit in the manual track idle confirmation area is confirmed to be idle, the target train is controlled to switch from the target authorization mode to the full monitoring mode.

[0059] In this step, the RBC detects that the estimated front end of the target train is within the manual track idle confirmation zone when it is not moving after starting. Therefore, the RBC sends a track circuit idle confirmation request to the ATP. Once the driver confirms that the track circuit is idle, the RBC sends a full monitoring mode driving permit to the ATP. ATP then controls the target train to switch from target authorization mode to full monitoring mode. This generates a target distance continuous speed control mode curve, using the section communication train or the next station approach signal as the protection endpoint, to implement moving block departure. In full monitoring mode, the target train can travel at a higher speed, and the ATP will continue to monitor the train's position and speed to ensure safe operation in full monitoring mode.

[0060] 103D. After it is estimated that the front end has entered the artificial track idle confirmation area and the track circuit in the artificial track idle confirmation area is confirmed to be idle, the target train is controlled to switch from the target authorization mode to the full monitoring mode.

[0061] In this step, since the estimated front end has not entered the artificial track idle confirmation area when the train is not moving after starting, but as the target train travels in the visual authorization mode, the position of its estimated front end will be continuously updated, and RBC will continue to detect whether the estimated front end of the target train enters the artificial track idle confirmation area. When it is detected that the estimated front end of the target train enters the artificial track idle confirmation area, its subsequent execution process is as described in step 103C, and the same content will not be repeated here.

[0062] Case 2: Based on the above description of the communication train controlling the target train to perform the driving operation according to the first departure strategy, the following steps 103E to 103F need to be performed:

[0063] 103E. If the train type is a visual authorization train, the length of the departure route will be used as the visual authorization distance, and the target train will be controlled to run in the target authorization mode.

[0064] In this step, the RBC generates the visual authorization information including the authorized distance and the balise list including the target train's track positioning balise, the departure balise and the balises on the departure route, taking the length of the whole departure route as the visual authorization distance. The RBC sends the visual authorization information to the ATP, and the ATP controls the target train to run in the target authorization mode according to the received visual authorization information. In the target authorization mode, the train runs at a lower speed to ensure that the driver can confirm the safety of the front line within the visual range, ensuring that there are no obstacles or other trains. The ATP continuously monitors the position and speed of the train to ensure that the train runs safely within the visual authorization distance.

[0065] 103F, when the estimated front end of the target train is detected to reach the departure balise, the target train is controlled to switch from the target authorization mode to the full supervision mode.

[0066] In this step, the RBC predefines the position of the departure balise, which is usually installed near the departure signal, for confirming that the train has prepared to leave the track and enter the departure route. Therefore, the RBC continuously detects whether the estimated front end of the target train reaches the position of the departure balise. When the estimated front end of the target train runs to the departure signal and triggers the departure balise, the ATP sends the RBC that the train position state is known. At this time, the RBC automatically upgrades the train type of the target train to the communication train, and sends the ATP the driving permission information of the full supervision mode. At this time, the ATP controls the target train to switch from the target authorization mode to the full supervision mode, i.e. generates the target distance continuous speed control mode curve, taking the interval communication train or the next station entry signal as the protection terminal, to realize the moving block mode departure. In the full supervision mode, the target train can run at a higher speed, and the ATP will continue to monitor the position and speed of the train to ensure that the train runs safely in the full supervision mode.

[0067] It should be noted that after step 103A or step 103E is executed, since the train-to-ground wireless communication state corresponding to the target train can also be disconnected due to the RBC receiving an ATP disconnection request or actively disconnecting with the ATP, or the communication signal is affected, etc., at this time, the RBC cannot normally receive the train position state report sent by the ATP, whether it is a communication train or a visual authorization train, the position is unknown, therefore, in order to ensure the running efficiency of the freight train and the system reliability. Also includes: if it is detected that the train-to-ground wireless communication state corresponding to the target train is disconnected or timed out, the train type is downgraded from a communication train or a visual authorization train to a non-communication train, the light display state of the target train is downgraded from lighting to lighting, the departure mode of the target train is moved from block to station block, and whether the departure route is open is detected based on the opening condition of the station block, and after confirming that the departure route is open, the target train is controlled to execute the train operation according to the second departure strategy.

[0068] In this step, since the RBC will continue to monitor the communication state with the ATP, if communication timeout or disconnection is detected, the RBC will record the event and take appropriate downgrade measures. And the downgrade measure can be to downgrade the train type from a communication train or a visual authorization train to a non-communication train, downgrade the original light display state from lighting to lighting, downgrade the original departure mode from mobile block to station block, and detect whether the departure route is open based on the opening condition of the station block, and after confirming that the departure route is open, control the target train to execute the train operation according to the second departure strategy. Specifically, if the communication is disconnected or timed out, the target train has entered the visual authorization mode, then the target train stops, the driver gets the dispatcher's authorization, and the ATP is operated to enter the backup mode. If the communication is disconnected or timed out, the target train has not entered the visual authorization mode, then the driver gets the dispatcher's authorization, and the ATP is directly operated to enter the backup mode, at this time, the ATP controls the train to run at a speed lower than the fixed speed limit according to the fixed speed limit of the backup mode. The ATP continues to monitor the position and speed of the train to ensure safe driving of the train in the backup mode. The driver observes the front line according to the indication of the backup mode to ensure that there is no obstacle or other train. When the target train reaches the outbound transponder, the ATP reads the block authorization information in the transponder, and the ATP generates a target distance continuous speed control mode curve according to the block authorization information to ensure safe driving of the train in the backup mode.

[0069] 104、If the train type is a hidden train or a non-communication train, control the signal of the departure route to be lit, and detect whether the departure route is open based on the opening condition of the station block, and after confirming that the departure route is open, control the target train to execute the train operation according to the second departure strategy.

[0070] The second departure strategy is used to represent the transition strategy based on the hidden train or non-communication train to the backup mode.

[0071] It should be noted that the specific execution process of controlling the target train to perform the train operation according to the second departure strategy after confirming that the departure route is open is as follows: if the train type is a hidden train or a non-communication train, the target train is controlled to run in the backup mode.

[0072] In this step, the radio block center (RBC) sends the train type to the train control and interlocking integrated device (TIS) according to the train type being a hidden train or a non-communication train. The TIS controls the signal of the departure route to be lit according to the train type being a hidden train or a non-communication train, and checks the opening conditions of the departure route according to the inter-station block mode, including the departure direction and whether the target section is idle. Specifically, the target section can be determined according to the departure direction of the target train, and whether the target section is idle can be determined based on the section axle state and the section track circuit state corresponding to the target section. If yes, it is determined that the departure route can be opened, and if no, it is determined that the departure route cannot be opened. That is, when the TIS confirms that the section axle state and the section track circuit state are both idle, it is determined that the target section is idle, and otherwise it is determined that the target section is not idle.

[0073] After confirming that the departure route is open, the TIS opens the departure signal and continuously monitors the state of the departure signal. Since the hidden train or the non-communication train is to run in the backup mode, after the driver gets the authorization from the dispatcher, the ATP is operated to transition into the backup mode. At this time, the ATP controls the train to run at a speed lower than the fixed speed limit according to the fixed speed limit of the backup mode. When the train reaches the exit transponder, the ATP obtains the block authorization information, generates a target distance continuous speed control mode curve, and monitors the safe operation of the train.

[0074] Based on the above Figure 1As can be seen from the implementation mode of the application, the freight train dispatching management method of the new train control operation control system provided by the application is that when it is necessary to perform train dispatching management on a freight train, the train type of a target train is determined according to a train-ground wireless communication state and a train position state report, the train type includes a hidden train, a non-communication train, a communication train and a visual authorization train, the light display state and the dispatching mode of the target train are determined based on the train type, the light display state includes light-off and light-on, and the dispatching mode includes block sectioning and moving block sectioning, if the train type is the communication train or the visual authorization train, the signal of the dispatching route is controlled to be light-off, it is detected whether the dispatching route is open based on the open condition of the moving block sectioning, and after confirming that the dispatching route is open, the target train is controlled to perform train operation according to a first dispatching strategy, if the train type is the hidden train or the non-communication train, the signal of the dispatching route is controlled to be light-on, it is detected whether the dispatching route is open based on the open condition of the block sectioning, and after confirming that the dispatching route is open, the target train is controlled to perform train operation according to a second dispatching strategy. The technical solution provided by the application automatically determines the train type of the target train as the hidden train, the non-communication train, the communication train or the visual authorization train and the like through the train-ground wireless communication state and the train position state report, eliminates the disadvantages of relying on manual input information of the driver, reduces the labor intensity caused by human operation, and reduces the possibility of operation errors. The light display state of light-off or light-on and the dispatching mode of the block sectioning or the moving block sectioning are automatically determined based on the train type, for the communication train and the visual authorization train, light-off and the moving block sectioning are adopted to detect whether the dispatching route is open, for the hidden train and the non-communication train, light-on and the block sectioning are adopted to detect whether the dispatching route is open, and after confirming that the dispatching route is open, the corresponding dispatching strategy is adopted to perform train operation. This way not only can better adapt to different types of trains and complex station environments, reduce delays caused by human factors, improve the dispatching frequency and transportation efficiency, but also can ensure the safe operation of the train, thereby significantly improving the operation efficiency and safety of the freight railway, and providing strong support for the efficient operation of the freight railway.
