Abstract
Description
Technical Field
[0001] This application relates to the field of rail transit technology, specifically to a method, device, equipment, and storage medium for issuing temporary speed limits for trains. Background Technology
[0002] In the upgrade and renovation of the moving block system for freight railways, it is necessary to define the jurisdiction of the newly added Radio Block Center (RBC) and Temporary Speed Limit Server (TSRS). To calculate reliable train operation permits, the RBC needs to interact with the computer interlocking systems (CIs) within its jurisdiction in real time. One RBC can manage multiple CIs, while a single CI is managed by only one RBC. The TSRS can receive temporary speed limit commands issued by the CTC and forward the corresponding speed limit information to the RBC, which then issues it to the train. A single TSRS only receives speed limit commands from one fixed CTC, and its jurisdiction boundary remains consistent with that of the CTC. Under the existing train control system, the communication relationship between the TSRS and RBC is "one-to-many," meaning that a single RBC obtains speed limit information from only one TSRS.
[0003] However, considering that the operation types of each CI station on the existing freight railway line are different and the line conditions are more complex than those of ordinary passenger lines, the RBC's ability to calculate train operation permits for multiple trains at the same time is limited. Therefore, when encountering large freight operation stations, the scope of CI stations that the RBC can manage is limited. When the jurisdiction of the RBC overlaps with the jurisdiction of two CTCs at the same time, temporary speed limit information cannot be issued normally. Summary of the Invention

[0011] In an optional embodiment of this application, the step of receiving and executing the temporary speed limit command issued by the first CTC and the second CTC by the common RBC of the first speed limit area and the second speed limit area further includes:
[0012] After the common RBC of the first and second speed limit areas receives the temporary speed limit command issued by the first CTC and the second CTC, if the speed limit values of the first and second speed limit areas are the same, the first and second speed limit areas are spliced together to form a continuous speed limit area, and the common RBC executes the temporary speed limit command in the continuous speed limit area.
[0013] In an optional embodiment of this application, the step of issuing temporary speed limit orders to the first speed limit area and the second speed limit area via the first CTC and the second CTC respectively further includes:

[0018] The RBC calculates the train operation permit based on the train position information and CI status information, and adds the temporary speed limit start information and temporary speed limit end information to the train operation permit according to the temporary speed limit order.
[0019] In one optional embodiment of this application, the CI status information includes at least one of section, road, and turnout status information.
[0020] According to a second aspect of the embodiments of this application, a temporary train speed limit issuing device is provided. The device includes a speed limit command issuing module, a speed limit execution differentiation module, and a unified speed limit execution module; wherein...
[0021] The speed limit command issuing module is used to issue temporary speed limit commands to the first speed limit area and the second speed limit area through the first CTC and the second CTC respectively; the first speed limit area and the second speed limit area are adjacent to each other;

[0028] In scenarios where the jurisdiction of the RBC overlaps with that of two CTCs, this application aims to ensure that temporary speed limit information can be completely transmitted to the RBC by having the RBC obtain temporary speed limit information from the TSRS under the jurisdiction of both CTCs simultaneously. Based on this, this application solves the problem that temporary speed limit information cannot be transmitted normally when the jurisdiction of the RBC overlaps with that of two CTCs during the upgrading and transformation of existing freight railway lines into moving block systems, due to the limitation of the RBC's ability to calculate train operation permits.

[0037] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.
[0038] First, let's explain the English abbreviations that appear in this embodiment:
[0039] IC: Integrated Circuit Chip;
[0040] CTC: Centralized Traffic Control System;
[0041] CI: Computer Interlocking;
[0042] RBC: Radio Block Center;
[0043] TSRS: Temporary Speed Restriction Server.
[0044] Temporary Speed Restriction Server (TSRS):
[0045] Currently, freight railways generally use three- or four-display fixed block signaling systems. Drivers operate trains with the assistance of train operation monitoring devices (e.g., LKJ2000, hereinafter referred to as LKJ). The LKJ device can prevent trains from overstepping signals and exceeding speed limits. The LKJ device needs to load temporary speed limit information pre-written into an IC card. During train operation, the LKJ integrates track information, temporary speed limit information, and train operation status to provide overspeed protection. Under the aforementioned fixed block signaling system, the centralized dispatching system (CTC) communicates with the computer interlocking system (CI) to transmit commands issued by the centralized dispatching system to the interlocking system; the CI sends real-time station information and various alarm information to the CTC.
[0046] In the upgrade and renovation of the freight railway moving block system, it is necessary to define the jurisdiction of the newly added Radio Block Center (RBC) and Temporary Speed Limit Server (TSRS). To calculate reliable train operation permits, the RBC needs to exchange information with the Control Centers (CIs) within its jurisdiction in real time. One RBC can manage multiple CIs, while a single CI is managed by only one RBC. The TSRS can receive temporary speed limit commands issued by the Control Center (CTC) and forward the corresponding speed limit information to the RBC, which then issues it to the train. A single TSRS only receives speed limit commands from one fixed CTC, and its jurisdiction boundary remains consistent with that of the CTC. Under the existing train control system, the communication relationship between the TSRS and RBC is "one-to-many," meaning that a single RBC obtains speed limit information from only one TSRS.
[0047] However, considering the varying operational types of CI stations on existing freight railway lines and the more complex line conditions compared to ordinary passenger lines, and given the limited capacity of the RBC to calculate train clearances for multiple trains simultaneously, the RBC's jurisdiction over large freight terminals is limited. Figure 2 As shown, when the jurisdiction of the RBC overlaps with the jurisdiction of two CTCs, temporary speed limit information cannot be sent normally.
[0048] Therefore, for the upgrading and transformation of the moving block system of existing freight railway lines, this application proposes a new method for issuing temporary speed limits to ensure the safe operation of trains.
[0049] Figure 1 For a flowchart of the train temporary speed limit issuance method provided in this application embodiment, please refer to [link / reference]. Figure 1 :
[0050] S1: Temporary speed limit orders are issued to the first speed limit zone and the second speed limit zone via the first CTC and the second CTC, respectively. Specifically, the first speed limit zone and the second speed limit zone are adjacent.
[0051] In practice, two adjacent speed limit zones are those under the jurisdiction of two different CTCs and whose corresponding speed limit zones coincide at the CTC boundary point.
[0052] In some embodiments of this application, the first CTC and the second CTC issue temporary speed limit orders to the first speed limit area and the second speed limit area through the first TSRS and the second TSRS, respectively; the jurisdiction of the first TSRS and the second TSRS is the same as that of the first CTC and the second CTC, respectively.
[0053] In some embodiments of this application, the RBC calculates the train operation permit based on the train position information and CI status information, and adds the temporary speed limit start information and temporary speed limit end information to the train operation permit according to the temporary speed limit order. Specifically, the CI status information includes at least one of section, road, and turnout status information.
[0054] For details regarding the information interaction method in the moving block control system proposed in this application embodiment, please refer to [link / reference needed]. Figure 3 In practical implementation, under the moving block control system, the CTC issues a temporary speed limit command to the TSRS. The TSRS forwards the temporary speed limit information corresponding to the received command to the RBC. The CI reports the status information of sections, routes, and switches within its jurisdiction to the ground RBC equipment in real time. The train reports its position information to the RBC in real time, and the RBC obtains the temporary speed limits within its jurisdiction. Based on the application of TSRS, trains can exchange information under the moving block control system. In the traditional fixed block system, the system cannot know the specific position of the train within a section, so the starting and ending points of train braking are always at the boundary of a certain section. To fully ensure safety, a protective section must be added between two trains, which results in a large safety interval between trains and affects the efficiency of line utilization. Based on the moving block control system combined in the embodiments of this application, train speed control can be improved, the safety interval between trains can be reduced, and the line utilization efficiency can be improved.
[0055] In some embodiments of this application, such as Figure 2 As shown, the jurisdiction of an RBC may overlap with that of two CTCs simultaneously; that is, two adjacent speed-limited zones may be governed by the same RBC but by different CTCs and TSRSs. In other embodiments of this application, the jurisdiction of the RBC may also be consistent with that of the CTC and TSRS.
[0056] Please continue reading Figure 1 :
[0057] S2: If the first speed limit zone and the second speed limit zone do not share a common RBC jurisdiction, then:
[0058] The first RBC, which governs the first speed limit zone, receives and executes the temporary speed limit order issued by the first CTC, and the second RBC, which governs the second speed limit zone, receives and executes the temporary speed limit order issued by the second CTC.
[0059] In some embodiments of this application, the first RBC and the second RBC calculate the train operation permit based on the train position information and CI status information, and add the temporary speed limit start information and temporary speed limit end information to the train operation permit according to the temporary speed limit order.
[0060] In practice, for scenarios where the jurisdiction of an RBC only overlaps with that of a single CTC, the RBC can be managed by a single TSRS. After receiving a temporary speed limit order from the CTC, the TSRS will forward the temporary speed limit information to the RBC under the jurisdiction of the line, so that the RBC can manage trains passing through this temporary speed limit area.
[0061] In scenarios where the jurisdiction of an RBC overlaps only with that of a single CTC, the issuance, receipt, and execution of speed limit commands in two adjacent speed limit zones are performed separately and with substantially the same steps. Therefore, in this embodiment, only one segment of the speed limit zone is selected for a detailed description of the issuance, receipt, and execution of speed limit commands. Figure 4 As shown, when there is a continuous temporary speed limit on the CI1 to CI2 line, the dispatcher issues a corresponding speed limit command to the TSRS from the CTC. After receiving the speed limit command, the TSRS confirms that the continuous speed limit area is within the jurisdiction of RBC1. That is, in this embodiment, the jurisdiction of RBC is consistent with that of CTC and TSRS. The speed limit area is then forwarded to RBC, so that RBC obtains the temporary speed limit information.
[0062] Based on this, the train reports its location information to the controlled RBC in real time. The RBC calculates the train's travel permit by combining the information on the section, route, and turnout status reported by the CI within its jurisdiction. When the RBC determines that the train's travel permit passes through a temporary speed limit area, it adds the determined information on the beginning and end of the temporary speed limit to the real-time travel permit information and sends it to the onboard equipment. The onboard equipment calculates the train's speed limit based on the real-time travel permit information and controls the train's speed to be reduced to less than or equal to the temporary speed limit value before the front of the train enters the beginning of the temporary speed limit. The train can run smoothly without stopping in the temporary speed limit area. It can accelerate again after the rear of the train has completely cleared the temporary speed limit area, which improves the train's operating efficiency while ensuring driving safety.
[0063] Please continue reading Figure 1 :
[0064] S3: If the first speed limit zone and the second speed limit zone are under the jurisdiction of a shared RBC, then:
[0065] The temporary speed limit order issued by the first CTC and the second CTC is received and executed by the shared RBC of the first and second speed limit zones.
[0066] Based on this, the embodiments of this application solve the problem that when upgrading and transforming existing freight railway lines into moving block systems, temporary speed limit information cannot be properly issued when the jurisdiction of the RBC overlaps with the jurisdiction of two CTCs due to the limitation of the RBC's ability to calculate train operation permits.
[0067] In some embodiments of this application, after the common RBC of the first speed limit area and the second speed limit area receives the temporary speed limit command issued by the first CTC and the second CTC, if the speed limit values of the first speed limit area and the second speed limit area are the same, the first speed limit area and the second speed limit area are spliced together to form a continuous speed limit area, and the common RBC executes the temporary speed limit command in the continuous speed limit area.
[0068] In some embodiments of this application, the common RBC calculates the train operation permit based on the train position information and CI status information, and adds the temporary speed limit start information and temporary speed limit end information to the train operation permit according to the temporary speed limit order.
[0069] In this embodiment, for scenarios where the jurisdiction of the RBC overlaps with that of two CTCs, in order to ensure that the temporary speed limit information can be completely sent to the RBC, the RBC obtains the temporary speed limit information from the TSRS under the jurisdiction of the two CTCs. For speed limit information where the speed limit area coincides at the CTC boundary point and the speed limit value is the same, the RBC determines it as a continuous temporary speed limit and splices it into a complete temporary speed limit area for train management.
[0070] like Figure 5As shown, when there is a continuous temporary speed limit on the CI4 to CI5 line, the dispatcher splits the temporary speed limit into two lines according to the jurisdiction of each CTC, and issues corresponding temporary speed limit commands to CTC1 and CTC2 respectively. After receiving the speed limit commands, TSRS1 and TSRS2 determine that the temporary speed limit area is within the jurisdiction of RBC2. TSRS1 sends temporary speed limit information 1 to RBC2, and TSRS2 sends temporary speed limit information 2 to RBC2. After receiving the commands, RBC confirms that the speed limit areas corresponding to temporary speed limit information 1 and temporary speed limit information 2 coincide at the CTC boundary point and have the same speed limit value, and then splices them together into a continuous temporary speed limit for management. Based on this, the train does not need to stop in the temporary speed limit area and runs smoothly. The train accelerates only after the rear of the train has completely cleared the temporary speed limit area, thus achieving continuous control of train operation and realizing continuous train control of the moving block system under the condition of temporary speed limits.
[0071] In this embodiment, the train reports its location information to the controlled RBC in real time. The RBC calculates the train's travel permit based on the status information reported by the CI within its jurisdiction. When the RBC determines that the train's travel permit passes through a temporary speed limit area, it adds the determined temporary speed limit start and end information to the real-time travel permit information and sends it to the onboard equipment. The onboard equipment calculates the train's speed limit based on the real-time received travel permit information and controls the train's speed to be reduced to less than or equal to the temporary speed limit value before the locomotive enters the temporary speed limit start position. This ensures train safety while improving train operating efficiency. Furthermore, using sections, roads, and switches as the status information content reported by the CI allows for more accurate calculation of train travel permits.
[0072] In some other embodiments of this application, if the speed limit values of two adjacent speed limit areas are inconsistent, the two speed limit areas are not spliced into a continuous temporary speed limit for management, but speed limit commands are issued separately for the two speed limit areas.
[0073] In summary, when the jurisdiction of the RBC overlaps only with the jurisdiction of a single CTC or with the jurisdiction of two CTCs, the RBC can obtain temporary speed limit information for the lines within its jurisdiction and thus manage trains passing through the temporary speed limit area.
[0074] It should be understood that although the steps in the flowchart are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order constraint on the execution of these steps, and they can be executed in other orders. Moreover, at least some steps in the diagram may include multiple sub-steps or multiple stages.

The execution order of these sub-steps or stages is not necessarily sequential, but can be performed alternately or in turn with other steps or at least some of the sub-steps or stages of other steps.
