Description

Technical Field

[0001] This invention relates to the field of train technology, and in particular to a method, apparatus, device and system for calculating mobility authorization based on the extension of a common area. Background Technology

[0002] In urban rail transit operations, the Communication Based Train Control (CBTC) system ensures safe operation by providing each train with a corresponding Movement Authority (MA). The Radio Blocking Center (RBC) is the core ground-based equipment in the moving block system. It calculates the Movement Authority (MA) for each train based on the train's reported head and tail positions, driving mode, route status reported by interlocking systems, input section occupancy or vacancy information, and turnout locking status.

[0003] In existing technology, to ensure efficient train operation through the switching of two RBCs, a shared management area is defined at the junction of two adjacent RBC areas. When the train fully enters the shared management area, the RBC switching is triggered. The maximum distance the MA (Moving Average) can be calculated to the station entrance signal. If the train is not a long train, the size of the shared management area is sufficient for normal train operation and entry into the station at normal speed. Figure 1 As shown, when the train has fully entered the area, the MA can extend ahead to take over the RBC, improving train operation efficiency.

[0004] However, under the moving block system, for 10,000-ton freight trains with long car bodies, if the movement authorization of 10,000-ton freight trains is managed based on the above-mentioned takeover method, the shared management area is short. As a result, before the driver fully enters the shared management area and triggers the RBC handover, he has to slow down and prepare to stop because the driving permission is short. This leads to a decrease in the operating efficiency of the train during the RBC handover process. Summary of the Invention

[0005] To overcome the problems existing in the related technologies, this disclosure provides a method, apparatus, device and system for calculating mobile authorization based on the extension of the common area, which addresses the problems existing in the prior art.

[0006] This specification provides one or more embodiments of a mobility authorization method based on a shared area extension, including:

[0007] According to preset conditions, the jurisdiction area of ​​the RBC under the takeover is extended to a preset boundary point outside the station to obtain the extended co-management area.

[0008] When a train is determined to enter a shared area, a registration request is sent to the takeover RBC so that the takeover RBC can calculate the initial MA2 corresponding to the train based on the registration request.

[0009] Based on the route processed by the computer interlocking system (CI) and the initial MA2, determine the final destination of MA2, update the initial MA2, and send it to the handover train; the determination of the final destination of MA2 includes the following step A:

[0010] Step A: Based on the station and line planning, if the route to be processed is not within the shared management area, the endpoint of the initial MA2 will be withdrawn to the starting signal of the route taking over RBC; if the route to be processed is within the shared management area and the endpoint of the initial MA2 is within the shared management area, the final endpoint of MA2 will be the endpoint of the initial MA2.

[0011] This specification provides one or more embodiments of a mobile authorization system based on a common area extension, including a RBC device, a train and computer interlocking (CI) communicatively connected to the RBC device, the RBC device including a takeover RBC;

[0012] The takeover RBC is used to: extend the managed area line to a preset boundary point outside the station according to preset conditions to obtain the extended shared management area; when a train enters the shared management area, receive a registration request to calculate the initial MA2 corresponding to the train; and based on the route processed by the computer interlocking CI and the initial MA2, determine and identify the final destination of MA2, update the initial MA2, and send it to the handover train; the determination of the final destination of MA2 includes the following steps:

[0013] Based on the station and line planning, if the route to be processed is not within the shared management area, the endpoint of the initial MA2 will be withdrawn to the starting signal of the route taking over the RBC; if the route to be processed is within the shared management area and the endpoint of the initial MA2 is within the shared management area, the final endpoint of MA2 will be the endpoint of the initial MA2.

[0014] This specification provides one or more embodiments of a computer-readable storage medium storing a computer program that, when executed by a processor, implements the steps of the mobility authorization method based on the common area extension described above.

[0015] This embodiment discloses a method, apparatus, equipment, and system for calculating movement authorization based on the extension of the shared management area. This technology extends the jurisdiction of the RBC (Railway Control Center) to a preset boundary point outside the station by setting preset conditions. When the train fully enters the shared management area, the MA (Movement Authorization) can be extended in a timely manner. Considering that the shared management area includes the station and has complex siding and connection tracks, when the route being processed is within the shared management area and the train can pass through the station normally, and when the route being processed includes turnout routes within the shared management area, the initial MA2 endpoint is withdrawn to the starting signal of the route being processed by the RBC. This embodiment not only solves the problem of unreasonable division of shared management areas, which causes long and heavy trains to need to slow down and cannot normally achieve RBC switching, but also greatly reduces the driver's operating pressure, improves the operating efficiency of large-tonnage freight trains, and is conducive to its promotion and application in large railway yards.

[0027] To enable those skilled in the art to better understand the technical solutions in one or more embodiments of this specification, the technical solutions in one or more embodiments of this specification will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this specification, and not all of the embodiments. Based on one or more embodiments of this specification, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this invention.

[0028] In existing technologies, due to the long length of railway lines and the large number of trains operating, multiple Railway Line Controllers (RBCs) are typically set up, each managing a certain area of ​​the line. The process of a train moving from one RBC's jurisdiction to the next is called an RBC handover. Generally, the RBC that leaves is called the handover RBC, and the RBC that is about to enter is called the takeover RBC.

[0029] In existing technologies, such as Figure 2 The diagram shown illustrates the existing mobility grant calculation scheme for RBC handover. The mobility grant calculation process for RBC handover is as follows:

[0030] Step 1: When the train has fully entered the shared area and the RBC handover calculation shows that the MA1 endpoint is the dividing point, the train triggers the RBC handover.

[0031] Step 2: When the train is completely in the handover area or the train cross-pressure boundary point, the starting point of MA1 for the handover train is calculated by the handover RBC as the minimum safety point of the train, and the ending point of MA1 is the boundary point of the switching area.

[0032] Step 3: When the train is completely in the handover area or the train crosses the pressure boundary point, the takeover RBC calculates that the starting point of MA2 of the handover train is the boundary point of the switching area, and the farthest end point of MA2 is the boundary point of the switching area.

[0033] Step 4: When the train is completely in the handover area or the train cross-pressure boundary point, the handover RBC or the takeover RBC splices MA1 and MA2 and sends them to the train.

[0034] Step 5: When the train is fully within the takeover area, cancel the transfer of the RBC.

[0035] During the movement authorization process of RBC handover, the boundary point of the shared area is generally set at the section between the two stations. During the handover, it is necessary to ensure that trains of any formation do not reduce speed. However, for example, for a 20,000-ton train with a length of approximately 2,700 meters, taking over the RBC requires determining the time needed to calculate the second movement authorization based on the highest speed of the RBC being handed over. This necessitates determining the length of the shared area required for calculating the second movement authorization. It is estimated that the length of the shared area for a 20,000-ton train with a length of approximately 2,700 meters should be at least 10,000 meters to ensure that the train does not reduce speed during the handover after fully entering the shared area. However, the shared area in the above method is too short to meet the calculation time of the movement authorization (MA), forcing the train to reduce speed while waiting for authorization, resulting in reduced train operating efficiency. Therefore, the above problem is an issue that this invention urgently needs to solve.

[0036] The present invention will now be described in detail with reference to specific embodiments and accompanying drawings.

[0037] Method Implementation Examples

[0038] According to embodiments of the present invention, a mobility authorization method based on extended common areas is provided, such as... Figure 3 The diagram shown is a flowchart of the mobility authorization method based on shared area extension provided in this embodiment. The mobility authorization method based on shared area extension according to this embodiment of the invention includes:

[0039] Step S1: Extend the jurisdiction area of ​​the RBC under the control of the RBC to a preset boundary point outside the station according to preset conditions to obtain the extended co-management area.

[0040] In this embodiment, the extended co-management area is estimated by the dispatcher based on the train's maximum operating speed and the time required for communication calculations.

[0041] Step S2: When it is determined that the train has entered the shared area, a registration request is sent to the takeover RBC so that the takeover RBC can calculate the initial MA2 corresponding to the train based on the registration request.

[0042] In this embodiment, the taking over RBC calculates the corresponding initial MA2 for the train according to the MA calculation principle based on the fixed information sent by the handover RBC and the train information.

[0043] Specifically, when a train travels within the jurisdiction of the transferred RBC, the transferring RBC calculates the MA1 (Movement Authorization 1) based on the turnout information, signal light information, and other trackside equipment information within its jurisdiction. At this time, the train travels according to the first movement authorization. When the train approaches the jurisdiction of the taking-over RBC and confirms entry into the shared management area, it sends a registration request to the taking-over RBC. The taking-over RBC, based on the route processed by Computer Interlocking (CI), determines the turnout information, signal light information, and other trackside equipment information within its jurisdiction and calculates the initial MA2 (Movement Authorization 2) for the train. The information exchange between the transferring RBC and the taking-over RBC allows for confirmation of turnout information within the shared management area, improving the accuracy of calculating the initial MA2 and MA1.

[0044] Step S3: Based on the route processed by the computer interlocking CI and the initial MA2, determine and identify the final destination of MA2, update the initial MA2, and send it to the handover train; the determination of the final destination of MA2 includes the following steps:

[0045] Step S31: Based on the station and line planning, if the route to be processed is not within the shared management area, the endpoint of the initial MA2 is withdrawn to the starting signal of the route taking over the RBC; if the route to be processed is within the shared management area and the endpoint of the initial MA2 is within the shared management area, the final endpoint of MA2 is the endpoint of the initial MA2.

[0046] In this embodiment, the computer interlocking CI is a control system that ensures the safe execution of transportation operations within the station. When the shared management area extends to the section outside the station, the train fully enters the shared management area and triggers the RBC switch. If the maximum safe forward position of the communication train has not crossed the RBC boundary point, the system controls the signals and switches in the station according to the route arranged for the train by the computer interlocking CI, takes over the RBC, matches the train with a route according to the route information input by the interlocking, and calculates the initial MA2 for the train.

[0047] However, as the shared management area extends, extending the boundary points to sections outside the station, the shared management area includes the station, resulting in complex siding and train arrival / departure tracks. This affects the calculation of movement authorization for the takeover RBC during handover. Based on this, this embodiment determines whether the processed siding and train arrival / departure routes fall within the shared management area according to the different siding and train arrival / departure routes processed by the computer interlocking system (CI), and then adopts different movement authorization calculation methods.

[0048] It should be noted that whether the route is within the shared management area depends on the route being processed. This determines whether the route is a main line or a turnout line combining main and side tracks within the shared management area. If the route is a turnout line combining main and side tracks, it means that the train needs to change its route to pass through the shared management area. The train needs to reduce its speed when passing through the turnout line. Therefore, the initial terminus of MA2 is withdrawn to the starting signal of the route that takes over RBC.

[0049] This embodiment extends the jurisdiction of the RBC takeover area to a preset boundary point outside the station by setting pre-defined conditions. When the train fully enters the shared area, the MA can extend in time. Considering that the shared area includes the station and has complex siding and connection tracks, when the route being processed is within the shared area and the train can pass through the station normally, and when the route being processed includes turnouts within the shared area, the initial MA2 endpoint is withdrawn to the starting signal of the route taking over the RBC. This embodiment not only solves the problem of unreasonable division of the shared area, which causes long and heavy trains to need to slow down and cannot normally achieve RBC switching, but also greatly reduces the driver's operating pressure, improves the operating efficiency of large-tonnage freight trains, and is conducive to its application in large railway yards.

[0050] In some embodiments, there is a situation where the endpoint of MA2 exceeds the boundary point of the shared management area. Specifically, when the initial MA2 is calculated by the takeover RBC, if the road segment behind the endpoint of the calculated MA2 is a default open road segment of the section and does not require interlocking processing, the takeover RBC will extend the endpoint of MA2 to the endpoint of the open road segment. In this case, the endpoint of MA2 may exceed the preset boundary point of the shared management area. Therefore, in order to optimize the application scenarios and safety range of the method in this embodiment, the determination of the final endpoint of MA2 also includes the following steps:

[0051] Step S32: If the route being processed is within the shared management area and the endpoint of the initial MA2 exceeds the boundary point of the shared management area, then the endpoint of the initial MA2 shall be withdrawn to the boundary point of the shared management area.

[0052] The following specific examples illustrate how the final destination of MA2 is determined in each scenario of this embodiment.

[0053] Scene 1.

[0054] refer to Figure 4 The diagram shown illustrates the takeover of RBC movement authorization during train handover under Scenario 1 conditions provided in this embodiment. Figure 4In this scenario, the vehicle reception route processed by the computer interlocking (CI) is the X-SI vehicle reception route. The endpoint of the MA2 calculation (corresponding to the dotted circle in the diagram) is within the shared management area, and all sections within MA2 are within the (preset) shared management area. At this time, the MA2 information is not adjusted.

[0055] Scene 2.

[0056] refer to Figure 5 The diagram shown illustrates the takeover of RBC movement authorization during train handover under Scenario 2 conditions provided in this embodiment. Figure 5 In this scenario, the receiving route handled by the computer interlocking (CI) is X-SI-XI-SN. Since the route of the section after the SN signal is open by default and does not require interlocking to handle, the MA2 endpoint hits the SN signal and then the next section signal. This causes the MA2 endpoint, which is being calculated by the RBC, to extend beyond the boundary point (the endpoint exceeds the signal outside the boundary point) and is not within the shared management area. Instead, it crosses the boundary point of the shared management area. In this case, the MA2 endpoint needs to be pulled back to the boundary point of the shared management area. After the pullback, all sections within the range of MA2 are within the shared management area.

[0057] Scene 3.

[0058] refer to Figure 6 The diagram shown illustrates the takeover of RBC movement authorization during train handover under scenario three conditions provided in this embodiment. Figure 6 In this scenario, the receiving route handled by the computer interlocking (CI) is the X-S3-X3-SN lateral line route. The RBC (Railroad Control Center) calculates that the endpoint of MA2 is within the shared management area, but a section of the track survey route corresponding to MA2 is not within the shared management area. Therefore, MA2 needs to be reverted, and its endpoint calculated to the starting point of the managed route at signal X.

[0059] Scene 4.

[0060] refer to Figure 7 The diagram shown illustrates the takeover of RBC movement authorization during train handover under scenario four conditions provided in this embodiment. Figure 7 In this scenario, the train reception route processed by the computer interlocking (CI) is the X-S3-X3-SN siding route. Since the route in the section is open by default, no interlocking processing is required. If the RBC matches the train with the route in the section, causing the MA2 endpoint calculated by the RBC to extend beyond the boundary point and outside the shared management area, crossing the boundary point of the shared management area, the MA2 endpoint needs to be first moved back to the boundary point of the shared management area. After the move, some sections within the MA2 range are outside the shared management area, so MA2 needs to be moved back again, and the MA2 endpoint calculated to the X signal at the beginning of the processed route.

[0061] Scene 5.

[0062] refer to Figure 8 The diagram shown illustrates the takeover of RBC movement authorization during train handover under scenario five provided in this embodiment. Figure 8 In this scenario, the receiving route processed by the computer interlocking (CI) is route X-S3. When the endpoint of MA2 calculated by the control RBC is not within the shared management area, has not crossed the boundary point of the shared management area, and some sections within MA2 are not within the shared management area, MA2 needs to be withdrawn. The endpoint of MA2 is then calculated to the X signal at the beginning of the processed route.

[0063] In this embodiment, for the takeover RBC, the train requests MA from the takeover RBC. The takeover RBC calculates the corresponding MA2 for the train (takeover RBC) according to the MA calculation principle based on the fixed information sent by the handover RBC and the train information. After the MA2 information is adjusted according to the different scenarios mentioned above, the takeover RBC sends the adjusted MA2 information to the handover RBC.

[0064] In one embodiment, trains can travel within the shared area according to the target movement authorization, avoiding large speed fluctuations when switching movement authorizations due to the large difference in road information between the takeover area controller and the handover area controller. This embodiment also includes: if the determination result of the final destination of MA2 does not include steps 31 and 32, then the takeover RBC does not send the handover status information of the train to the handover RBC.

[0065] In some embodiments, in addition to considering the impact of a reasonable MA endpoint on train operation efficiency, in order to improve the rationality of train movement authorization calculation and the safety of train operation within the entire takeover area controller, this embodiment further includes: based on the MA1 calculated by the handover RBC, if the endpoint of MA1 crosses or coincides with the boundary point of the shared area, and the line range of MA1 is within the shared area, then the handover RBC triggers RBC switching; if the line range of MA1 is not within the shared area, the handover RBC cannot trigger RBC switching.

[0066] In some embodiments, in order to monitor the status changes of equipment within a shared area in real time, and to ensure timely response by both handing over the RBC and taking over the RBC when an unsafe change occurs in the status of equipment within the shared area, thereby improving the system's response time to equipment failures, this embodiment further includes:

[0067] Based on the topology of the railway map and the turnout status of the computer interlocking (CI), in the direction of train operation, the distances from the ends of MA1 and MA2 to the front of the train are compared according to the obtained ends of MA1 and MA2.

[0068] System Implementation Examples

[0069] According to embodiments of the present invention, a mobile authorization system based on extended common areas is provided, such as... Figure 9 The diagram shown is a block diagram of a mobile authorization system based on extended common areas provided in this embodiment. According to an embodiment of the present invention, the mobile authorization system based on extended common areas includes:

[0070] Includes an RBC device, a train 10 that is communicatively connected to the RBC device, and a computer interlocking CI 20.

[0071] The RBC device includes a takeover RBC 30, which is used for: extending the managed area line to a preset boundary point outside the station according to preset conditions to obtain the extended shared management area; receiving a registration request to calculate the initial MA2 corresponding to the train 10 when the train 10 enters the shared management area; and determining the final destination of MA2 based on the route processed by the computer interlocking CI 20 and the initial MA2, updating the initial MA2 and sending it to the handover train 10; the determination of the final destination of MA2 includes the following steps:

[0072] Based on the station and line planning, if the route to be processed is not within the shared management area, the endpoint of the initial MA2 will be withdrawn to the starting signal of the route taking over RBC 30; if the route to be processed is within the shared management area and the endpoint of the initial MA2 is within the shared management area, the final endpoint of MA2 will be the endpoint of the initial MA2.

[0073] In this embodiment, the jurisdiction of the takeover RBC 30 is extended to a preset boundary point outside the station by pre-defined conditions. When the train 10 fully enters the shared area, the MA can be extended in time. Considering that the shared area includes the station and has complex siding and connection tracks, when the computer interlocking CI 20 processes the route within the shared area and the train 10 can pass through the station normally, when the processed route includes a turnout route within the shared area, the takeover RBC 30 will withdraw the initial MA2 endpoint to the starting signal of the takeover RBC route. This embodiment not only solves the problem of unreasonable division of the shared area, which causes long and heavy trains to need to slow down and cannot normally achieve RBC switching, but also greatly reduces the driver's operating pressure, improves the operating efficiency of large-tonnage freight trains, and is conducive to its application in large railway yards.

[0076] In some embodiments, in addition to considering the impact of reasonable planning of the MA endpoint on the train's operating efficiency, in order to improve the rationality of train movement authorization calculation and the safety of train operation within the entire takeover area controller, the RBC device in this embodiment also includes a handover RBC 40.

[0077] The handover RBC 40 is used to: calculate MA1, and determine whether the endpoint of MA1 crosses or coincides with the boundary point of the shared area, and the line range of MA1 is within the shared area, then triggering RBC handover; if the line range of MA1 is not within the shared area, then RBC handover cannot be triggered.

[0078] In some embodiments, in order to monitor the status changes of equipment in the shared area in real time, when an unsafe change occurs in the status of equipment in the shared area, both the handover of RBC 40 and the takeover of RBC 30 can respond in a timely manner, thereby improving the system's response time to equipment failures. In this embodiment, the RBC equipment is also equipped with a monitoring module, which is used to compare the distances of the endpoints of MA1 and MA2 from the train head based on the topology of the line map and the turnout status reported by the interlocking system, in the direction of train operation, according to the obtained endpoints of MA1 and MA2.

The mobility authorization method based on the extension of the common area as described in any one of claims 1-2, characterized in that, It also includes the following steps: Based on the topology of the railway map and the turnout status reported by the computer interlocking (CI), in the direction of train operation, the distances from the ends of MA1 and MA2 to the front of the train are compared according to the obtained ends of MA1 and MA2.

5. A mobile authorization system based on a shared management area extension, comprising a Railroad Controller (RBC) device, and a train and computer interlocking (CI) system communicatively connected to the RBC device, characterized in that, The RBC device includes a receiver RBC; The RBC takeover is used to: extend the managed area line to a preset boundary point outside the station according to preset conditions to obtain the extended shared management area; and when it is determined that a train has entered the shared management area, receive a registration request to calculate the initial MA2 corresponding to the train. And based on the route processed by the computer interlocking system (CI) and the initial MA2, determine and identify the final destination of MA2, update the initial MA2, and send it to the handover train; the determination of the final destination of MA2 includes the following steps: Based on the station and line planning, if the route to be processed is not within the shared management area, the endpoint of the initial MA2 will be withdrawn to the starting signal of the route taking over RBC; if the route to be processed is within the shared management area and the endpoint of the initial MA2 is within the shared management area, the final endpoint of MA2 will be the endpoint of the initial MA2. If the route is within the shared management area and the endpoint of the initial MA2 exceeds the boundary point of the shared management area, then the endpoint of the initial MA2 will be withdrawn to the boundary point of the shared management area.

6. The mobile authorization system based on extended shared area as described in claim 5, characterized in that, The RBC device also includes a handover RBC; The handover of RBC is used to: calculate MA1, and determine if the endpoint of MA1 crosses or coincides with the boundary point of the shared area, and the line range of MA1 is within the shared area, then the handover of RBC triggers RBC handover; if the line range of MA1 is not within the shared area, the handover of RBC cannot trigger RBC handover.

7. The mobile authorization system based on extended shared management area as described in claim 5, characterized in that, The RBC equipment also includes a monitoring module, which, based on the track map topology and the turnout status reported by the interlocking system, compares the distances of the endpoints of MA1 and MA2 from the train head along the train's running direction, according to the obtained endpoints of MA1 and MA2.

8. A computer-readable storage medium storing a computer program, characterized in that, When the computer program is executed by a processor, it implements the steps of the mobility authorization method based on the extension of a common area as described in any one of claims 1 to 4.
