Description

Technical Field

[0001] This invention relates to the field of train dispatching and power supply dispatching technology, and in particular to a collaborative method and architecture for train dispatching and power supply dispatching that integrates data from multiple systems. Background Technology

[0002] In recent years, with the rapid development of railway informatization and intelligentization, the application of emerging technologies such as big data, artificial intelligence, and cloud computing has been deepening, promoting the effective integration of internal and external railway data resources and bringing new development opportunities for railway command and dispatch, train control, and passenger services.

[0003] Train dispatching coordinates train operations based on train schedules and actual track conditions, undertaking crucial functions such as operational organization, safety assurance, real-time monitoring, and operational adjustments; it is the core of railway command and dispatch. Power supply dispatching handles routine planned maintenance, power outages and restorations, and emergency response. Since high-speed railway trains use electric traction, power supply dispatching is critical to ensuring normal train operation. Train dispatching and power supply dispatching work together to complete tasks such as construction and maintenance, train safety control, and emergency response, which are essential for the production efficiency and operational safety of high-speed railways.

[0004] To improve operational reliability under complex railway network conditions and accelerate the development of high-speed rail command and dispatch towards informatization, automation, and intelligence, the Centralized Traffic Control (CTC) system needs to interact and integrate with more systems, broaden the data sources of the system, and enhance the security checks of centralized dispatch control.

[0005] Option 1: Under the existing conditions, the various systems involved in power outage and restoration operations, including the CTC system, the Railway Power Supply Dispatching Intelligent Management System (PDMS), the Supervisory Control and Data Acquisition (SCADA) system, and the Transport Dispatching Management Information System (TDMS), are all independently constructed. Data silos exist between these systems, and the entire operational process relies on manual interaction. Train dispatchers and power supply dispatchers need to communicate work plans by telephone, record work information in paper documents, and manually review the work content to ensure accuracy. Then, the train dispatcher manually drafts dispatch orders or work instructions and issues them to the executing department. Upon receiving the instructions, station duty officers manually perform condition checks and control operations to ensure operational safety.

[0006] However, the shortcomings of Option 1 are: (1) The interaction process is cumbersome and the operation efficiency is low. At present, there are hundreds of daily power outage and restoration operation plans at the railway bureau level. During large-scale maintenance operations, the number of daily plans will increase significantly and the content will be more complex. Train dispatchers and power supply dispatchers need to communicate and confirm the operation plan repeatedly through telephone, paper documents and other means, and check the construction number, operation time, scope involved, train number affected, etc., manually set the contact network status and issue dispatch orders station by station. The dispatchers have a large workload and the communication takes too long, which seriously limits the improvement of the efficiency of track maintenance. (2) Manual setting of control has high safety risks. During the process of manually transmitting and transferring the construction plan between multiple systems, information omissions and errors are likely to occur. In particular, if the train operation data and the power supply arm status data are not connected, and control is only achieved manually by the dispatcher, it may cause accidents such as electric locomotives entering the power-off area and incorrectly supplying power to the power-off area, which seriously threatens the safety of train operation, facilities and personnel. (3) Lack of intelligent collaboration and poor emergency response capabilities. Because systems such as CTC, PDMS, SCADA, and TDMS are built and operated independently, data is fragmented and standards are inconsistent. When system failures, extreme weather, or other emergencies occur and multiple systems and departments need to coordinate emergency repairs, repeated information verification will seriously affect the efficiency of fault recovery. Relying solely on the work experience of dispatchers is also insufficient to effectively cope with complex emergency scenarios.

[0007] Option 2: In response to the expanding scale of high-speed railway operations and the increasingly heavy workload of maintenance tasks, some railway bureaus have improved the coordination methods of train dispatching and power supply dispatching. The main approach is to design an interoperability scheme between PDMS and SCADA / CTC systems based on the PDMS platform, realize information interaction through system interfaces, thereby digitizing the power outage and restoration signing process, and standardizing and regulating the operation-related instructions, which to a certain extent improves the reliability of interactive information and the efficiency of operation and construction. For example: (1) Qian Li et al., "Information Technology for Coordination of Power Supply Dispatch and Train Dispatch Power Outage and Restoration Operations", China Railway, December 2024; (2) Chinese Invention Patent No. CN117853057A, "Integrated Operation Management Information System and Card Control Method for Railway Train Power Supply Dispatch", April 9, 2024.

[0008] However, the shortcomings of Scheme 2 are: (1) Train scheduling and power supply scheduling are still carried out independently, and the collaboration is not in-depth. The existing scheme takes power supply scheduling as the core. In the scheme design, less consideration is given to train scheduling, which directly affects the efficiency of operation and safety control. Train scheduling and power supply scheduling are still executed separately, and no true collaboration is achieved. (2) Information is only interconnected and shared, and no deep integration is carried out. In the existing scheme, data sharing is still in the information interaction stage. Multi-source heterogeneous data has not been integrated, mined and analyzed, and the value of data has not been fully utilized. (3) Only the electronic signing of power outage and restoration has been realized. The level of automation and intelligence of the entire operation and construction process needs to be improved.

[0009] In summary, under the current operating methods, data between systems are isolated and processes rely on manual communication for confirmation, resulting in many problems such as long operation time, high safety risks, and heavy pressure on dispatchers. There is an urgent need to study train dispatching coordination methods to achieve multi-system data interconnection and automatic safety control, thereby significantly improving the informatization, automation, and intelligence level of train dispatching.

[0010] In view of this, the present invention is hereby proposed. Summary of the Invention

[0011] The purpose of this invention is to provide a collaborative method and architecture for train scheduling and power supply scheduling that integrates data from multiple systems. This method can fully integrate data from different systems, achieve collaborative train scheduling and power supply scheduling, and improve the automation and intelligence level of the entire operation and construction process.

[0012] The objective of this invention is achieved through the following technical solution: A collaborative method for train dispatching and power supply dispatching, incorporating multi-system data fusion, includes: The CTC system is configured with interface servers to interconnect with various external systems, enabling data interaction with these external systems. These external systems include: PDMS system, SCADA system, and TDMS system. Among them, the CTC system is a centralized dispatch control system, the PDMS system is an intelligent management system for railway power supply dispatch, the SCADA system is a data acquisition and monitoring control system, and the TDMS system is a transportation dispatch management system. When the CTC system receives a power outage request from the PDMS system, it parses the request and, based on the type of power outage request and the construction plan from the TDMS system or the fault repair operation information from the PDMS system, reviews the parsing results in one or more steps to determine whether to approve the power outage request. If the CTC system approves the power outage request, it will visualize the power supply information on the station map display terminal based on the real-time status of the power supply arm from the SCADA system. In addition, based on the analysis results of the power outage request and the real-time status of the power supply arm from the SCADA system, it will draw prompt boxes related to the power outage request on the operation map of the operation map terminal. When the CTC system receives power restoration confirmation information from the PDMS system, it reviews the cancellation operation command application submitted by the PDMS system. Once the review is approved, the power restoration process is initiated. Throughout the entire process from receiving a power outage request from the CTC system to the final restoration of power, the CTC system, PDMS system, and SCADA system work together to perform safety checks based on preset safety inspection conditions.

[0013] A collaborative architecture for train dispatching and power supply dispatching, based on a CTC system and fused with multi-system data, is used to implement the aforementioned method. It includes a data acquisition layer, a data governance layer, a fusion analysis layer, and a collaborative application layer. The data acquisition layer is responsible for collecting data, and the data governance layer is responsible for preprocessing the collected data. Both are located in the interface server of the CTC system. The interface server is selected as an edge device for interconnection with various external systems to realize data interaction between the CTC system and various external systems. The external systems include: PDMS system, SCADA system, TDMS system and neighboring station CTC system. Among them, the CTC system is a centralized dispatch control system, the PDMS system is an intelligent management system for railway power supply dispatch, the SCADA system is a data acquisition and monitoring control system, and the TDMS system is a transportation dispatch management system. The fusion analysis layer is used to parse power outage requests received from the PDMS system; The collaborative application layer is used to perform one-step or multi-step review of the parsing results based on the type of power outage request, combined with the construction plan from the TDMS system or the fault repair operation information from the PDMS system, to determine whether to approve the power outage request. When approving the power outage request, it visualizes the power supply information on the station map display terminal, combining the real-time status of the power supply arm from the SCADA system, and displays relevant prompt boxes on the operation map terminal based on the parsing results of the power outage request and the real-time status of the power supply arm from the SCADA system. Upon receiving power restoration confirmation information from the PDMS system, it combines PDM... The S system reviews the cancellation operation order application submitted, and after approval, initiates the power restoration process. Furthermore, throughout the entire process from receiving the power outage application to final power restoration, it coordinates with the PDMS and SCADA systems for safety control based on preset safety check conditions. It also interacts with the neighboring CTC system to exchange vehicle status command information, enabling automatic approval of cross-center power outage operations. This automatic approval means that when the power outage operation involves the jurisdiction of a neighboring CTC system, the CTC system sends relevant information to the neighboring CTC system during the review of the power outage application and obtains the neighboring CTC system's consent.

[0014] As can be seen from the technical solutions provided by the present invention above: In terms of operational efficiency: (a1) Through multi-source data fusion, the power outage application content is automatically processed, avoiding the risk of incorrect route setting, omission, and incorrect power outage / suppression caused by human error; (a2) The entire process of train dispatching is electronic and automated. In the experimental environment, the average time for power outage / suppression signature and instruction issuance is shortened by 80.7% compared with the traditional manual mode, which greatly improves the utilization rate of planned maintenance window operation time; In terms of safety management: (b1) Through power supply information visualization and operation diagram terminal layout, the power supply status of each line and station can be accurately, timely, and effectively prompted to the dispatcher, greatly reducing the number of misoperations caused by the dispatcher's incorrect or missed recording of power supply information; (b2) Introducing safety inspection conditions into the entire process for collaborative safety control can improve overall safety. Overall, this invention changes the traditional isolated and passive operation mode of train dispatching, and provides an effective solution to the problems of low operational efficiency, high safety risks and poor emergency response capabilities faced by existing dispatching. It significantly improves the efficiency and safety of high-speed rail command and dispatch, and is of great significance to the improvement of the dispatching and command level of high-speed railways.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0024] First, the following explanations are provided for the terms that may be used in this article: The terms "comprising," "including," "containing," "having," or other similar semantic descriptions should be interpreted as non-exclusive inclusion. For example, including a technical feature element (such as raw material, component, ingredient, carrier, dosage form, material, size, part, component, mechanism, device, step, process, method, reaction conditions, processing conditions, parameter, algorithm, signal, data, product or article of manufacture, etc.) should be interpreted as including not only the expressly listed technical feature element, but also other technical feature elements that are not expressly listed and are well-known in the art.

[0025] The following provides a detailed description of the collaborative method and architecture for train dispatching and power supply dispatching based on multi-system data fusion provided by this invention. Contents not described in detail in the embodiments of this invention are prior art known to those skilled in the art. Where specific conditions are not specified in the embodiments of this invention, they are performed according to conventional conditions in the art or conditions recommended by the manufacturer. Reagents or instruments used in the embodiments of this invention, unless otherwise specified, are all commercially available conventional products.

[0026] Example 1 This invention provides a multi-system data fusion method for coordinated train scheduling and power supply scheduling, such as... Figure 1 As shown, it mainly includes: 1. Interconnection of multiple systems.

[0027] Configure interface servers in the CTC system to interconnect with various external systems and enable data interaction with these external systems.

[0028] In this embodiment of the invention, the external systems include: PDMS system, SCADA system and TDMS system; wherein, CTC system is a centralized dispatch control system, PDMS system is an intelligent management system for railway power supply dispatch, SCADA system is a data acquisition and monitoring control system, and TDMS system is a transportation dispatch management system.

[0029] In this embodiment of the invention, the CTC system is also interconnected with the neighboring CTC system through an interface server to exchange driving status command information with the neighboring CTC system and realize automatic approval of cross-bureau power outage operations. The automatic approval of cross-bureau power outage operations means that when the scope of the power outage operation involves the jurisdiction of the neighboring CTC system, the CTC system sends relevant information to the neighboring CTC system when reviewing the power outage application and obtains the consent of the neighboring CTC system.

[0030] 2. Power outage requests are processed automatically.

[0031] In this embodiment of the invention, when the CTC system receives a power outage request from the PDMS system, it parses the request and, based on the type of power outage request, combines the construction plan from the TDMS system or the fault repair operation information from the PDMS system to conduct one or more steps of review on the parsing results to determine whether to approve the power outage request.

[0032] The preferred implementation method for this part is as follows: (A1) The CTC system receives a power outage request from the PDMS system. The power outage request corresponds to either a planned operation type or a fault repair operation type. When it corresponds to a planned operation type, the power outage request is generated by the PDMS system based on the construction plan of the TDMS system. When it corresponds to a fault repair operation type, the power outage request is generated by the PDMS system based on the fault repair operation information.

[0033] (A2) The power outage application is parsed to obtain key information, including: the power outage number, the power outage time, and the power outage area. Specifically: if the power outage information is structured text, the key information is directly extracted; if the power outage information is unstructured text, natural language processing technology is used to identify and extract the key information. Simultaneously, the corresponding work information for the power outage application is also parsed, which includes the relevant construction plan or fault repair work information.

[0034] (A3) If the power outage request provided by PDMS is a planned operation type, then, in conjunction with the construction plan from the TDMS system, it is determined whether it corresponds to the power outage scope and time obtained through parsing. If so, it is determined whether the power outage number in the construction plan is consistent with the power outage number obtained through parsing the power outage request. If they are consistent, the construction plan and the power outage request are associated and processed, and the process proceeds to the next step. If they are inconsistent, a power outage request conflict alarm is generated and feedback is sent to the PDMS system to reject the power outage request. If the power outage request provided by PDMS is a fault repair operation type, this step is ignored.

[0035] (A4) Check whether the following conditions are met: the work section involved in the work information is within the power outage area, the work time is within the power outage time, and there is no train operation plan within the corresponding time of the power outage area; if all conditions are met, proceed to the next step; if any condition is not met, an alarm for failure to pass the review will be automatically generated and feedback to the PDMS system to reject the power outage application.

[0036] (A5) Automatically draft power outage dispatch orders based on power outage requests.

[0037] (A6) Issue a power outage dispatch order. Select all the commanded locations by associating the power outage scope, automatically issue the power outage dispatch order and track the feedback status; if all commanded locations agree to the power outage application, then send feedback to the PDMS system to approve the power outage application; otherwise, generate an alarm indicating that the review has not passed and send feedback to the PDMS system to reject the power outage application.

[0038] 3. Power supply information visualization and automatic drawing of operation diagrams on the terminal.

[0039] In this embodiment of the invention, if the CTC system approves the power outage request, the power supply information is visualized on the station map display terminal based on the real-time status of the power supply arm from the SCADA system. In addition, based on the parsing result of the power outage request and the real-time status of the power supply arm from the SCADA system, a prompt box related to the power outage request is drawn on the operation map of the operation map terminal.

[0040] Preferably, the visualization of power supply information in the station map display terminal includes: if the CTC system approves the power outage application, a command is automatically triggered at the power outage time to set a power outage indicator, that is, the power outage status is displayed on the corresponding station and line in the station map display terminal; at the same time, the CTC system also directly obtains the real-time status of the power supply arm through the SCADA system, and automatically associates the power supply arm number with the range of lines and stations affected by the power supply arm, and displays it synchronously on the station map display terminal; when the power outage indicator does not match the actual status of the power supply arm, an alarm is generated that the power outage plan is inconsistent with the status of the power supply arm.

[0041] Furthermore, when the CTC system is connected to each external system normally, the power supply information is displayed visually on the station map display terminal. The station map display terminal is also used to view the connection status between the CTC system and each external system. The connection status is viewed by exchanging heartbeat data packets. A heartbeat data packet is sent every set time. If a heartbeat data packet is not received from a certain external system for a set number of consecutive times, the connection is considered to be interrupted. An alarm is given by indicating that the network link between the CTC system and the corresponding external system is disconnected, and reconnection is automatically initiated.

[0042] Preferably, the step of combining the analysis results of the power outage request with the real-time status of the power supply arm from the SCADA system to draw a prompt box related to the power outage request on the operation diagram of the operation diagram terminal includes: (B1) Determine the power outage time and scope based on the analysis results, and draw a power outage preparation prompt box on the operation diagram terminal.

[0043] (B2) Determine the timetable based on whether there is a train operation plan within the power outage area: If there is a train operation plan within the power outage area, then all operating lines involved within the power outage area will be automatically adjusted to generate a new timetable; otherwise, the timetable will not be adjusted.

[0044] (B3) Once the operation plan is finalized, it is prohibited to lay new operation lines within the power outage area.

[0045] (B4) If the power outage approval is received from PDMS, proceed to the next step; if not received, determine whether the current time has exceeded the start time of the power outage application. If it has, proceed to the abnormal handling process; otherwise, continue to wait for the power outage approval.

[0046] Specifically, the abnormal handling process includes: generating an alarm message that no power outage approval has been received; sending the alarm message to the PDMS system; switching to manual verification of the power outage status; if the power outage has occurred, returning a message that the power outage approval has been received; if the power outage has not occurred, withdrawing the power outage approval, canceling the power outage preparation prompt box, restoring the operation diagram, and ending the process.

[0047] (B5) Obtain the status of the power supply arm through the SCADA system, determine whether the power outage range is consistent with the actual power outage status of the power supply arm, if they are consistent, draw the power outage prompt box on the operation diagram terminal and replace the power outage prompt box, and the drawing process on the operation diagram terminal ends; otherwise, generate a power outage error alarm and send alarm information to the PDMS system and SCADA system.

[0048] 4. Automatic processing of power supply confirmation information.

[0049] In this embodiment of the invention, when the CTC system receives power supply confirmation information from the PDMS system, it reviews the cancellation operation command application submitted by the PDMS system, and then proceeds with the power restoration process after the review is approved.

[0050] 5. Train dispatching and power supply dispatching work together for safety control.

[0051] In this embodiment of the invention, throughout the entire process from receiving a power outage request from the CTC system to the final restoration of power, the CTC system, PDMS system, and SCADA system perform collaborative safety control based on preset safety check conditions.

[0052] The collaborative security control involved in this section mainly includes: (C1) Confirm Power Outage Information: The CTC system confirms the power outage information based on the type of the power outage application and in conjunction with the construction plan or fault repair operation information. This includes: after receiving the power outage application, parsing it. If the power outage application corresponds to the planned operation type, then in conjunction with the construction plan from the TDMS system, checking whether the parsed power outage number, power outage range, and power outage time are consistent with the power outage number, power outage range, and power outage time in the construction plan. If they are consistent, the check is passed. If it corresponds to the fault repair operation type, the check step is omitted, and the power outage information is directly parsed and confirmed.

[0053] (C2) Check power outage conditions: The CTC system checks that there are no trains running in the power outage area or that the trains have stopped properly, and that there are no train operation plans or that all train operation plans have been adjusted within the power outage area.

[0054] (C3) Confirm the scope of the power outage: If it extends to the adjacent dispatching station, the CTC system checks whether it has obtained the consent of the adjacent CTC system.

[0055] (C4) Generate a power outage dispatch order, that is: CTC sends a power outage dispatch order to all commanded locations within the power outage range and checks whether it has received an acceptance receipt from each commanded location.

[0056] (C5) Confirmation of power outage: After the CTC system sends the power outage application to the PDMS system, it receives the power outage approval from the PDMS system and issues it to each commanded location. It then checks whether it has received confirmation receipts from each commanded location. If the power outage extends to adjacent dispatch stations, it checks whether it has received confirmation receipts from the neighboring CTC system.

[0057] The above step (C1) corresponds to steps (A1) to (A3) in the aforementioned automatic power outage application processing process; the above step (C2) corresponds to step (A4) in the aforementioned automatic power outage application processing process; the above steps (C3) to (C5) correspond to steps (A5) to (A6) in the aforementioned automatic power outage application processing process, and also include a process of checking whether a confirmed power outage receipt has been received.

[0058] (C6) Paint the power outage warning box: The CTC system combines the analysis results of the power outage application with the real-time status of the power supply arm from the SCADA system to check whether the power outage warning box has been painted and prohibits trains from entering the power outage area.

[0059] Step (C6) here corresponds to steps (B1) to (B5) in the aforementioned automatic drawing process of the running graph terminal.

[0060] (C7) Prevent trains from entering the work area: After confirming that the power has been cut off, the CTC system checks whether any dispatchers have arranged train routes to the power outage area. If so, route arrangement is prohibited and a system alarm is generated.

[0061] (C8) Check power supply conditions: After receiving the power supply confirmation information provided by the PDMS system, the CTC system checks whether it is consistent with the information in the cancellation operation order application and whether there are no personnel working in the power outage area.

[0062] (C9) Generate power dispatch command: The CTC system sends power dispatch command to each command recipient and checks whether the command recipient has received an agreement receipt; if the power supply range extends to the adjacent dispatch station, it checks whether the neighboring bureau's CTC system has received an agreement receipt.

[0063] (C10) Cancel power outage message: The CTC system obtains the power supply arm status data through the SCADA system and checks whether it is consistent with the power supply range, power supply arm number, etc. in the power supply confirmation information. If so, the power outage message box is canceled.

[0064] The above-mentioned solution provided by the embodiments of the present invention can fully integrate data from different systems, realize the coordination of train scheduling and power supply scheduling, and improve the automation and intelligence level of the entire operation and construction process.

[0065] To more clearly demonstrate the technical solution and its effects provided by the present invention, the method provided by the embodiments of the present invention will be described in detail below with reference to specific examples.

[0066] This invention provides a collaborative method for train dispatching and power supply dispatching based on multi-system data fusion. First, it analyzes the data flow interaction requirements of multiple systems and designs a multi-system interconnection scheme. Second, based on the actual situation of high-speed rail command and dispatch, it studies the urgent issues of automatic processing of power outage requests, visualization of power supply information and automatic drawing of timetable terminals, and collaborative safety control technology. Detailed descriptions of each part follow.

[0067] I. Multi-system data flow analysis and network interconnection solutions.

[0068] Multi-system data sharing and interaction are the foundation for achieving scheduling coordination. In this embodiment of the invention, the main business data flow is as follows: Figure 2 As shown, the data sharing between the CTC system and other systems such as TDMS, PDMS, SCADA, and neighboring CTC systems enables the CTC system to incorporate multi-source data for in-depth fusion analysis, laying a solid foundation for automated workflows and comprehensive safety inspections.

[0069] 1. Interactive data flow analysis.

[0070] The CTC system obtains the construction plan from the TDMS system, reviews the power outage application submitted by the PDMS system based on the plan, and feeds back the operational data of the affected lines and the plan execution status to the TDMS. In this case, the power outage application is generated by the PDMS system based on the construction plan sent by the TDMS system. The CTC system and the PDMS system exchange power outage and restoration signature information, realizing the electronic and automated signature process, simplifying the interaction process between train dispatchers and power supply dispatchers, and improving signature efficiency. The CTC system obtains the energized status data of all power supply arms from the SCADA system, automatically sets the power outage status, and sends the real-time position information of all trains on the line to the SCADA system, thereby realizing dual prevention and control of risks such as trains entering power-deprived areas. In addition, the CTC system also exchanges train operation status command information with the CTC systems of neighboring bureaus, realizing automatic signature of cross-bureau power outage operations and multi-line collaborative safety control.

[0071] 2. Multi-system network interconnection solution.

[0072] The implementation of dispatching and coordination functions places higher demands on the real-time performance, stability, and security of data transmission between different systems. The CTC system not only possesses the capability to aggregate information from multiple sources but also directly undertakes the functions of train dispatching, command, and monitoring. Therefore, a system network interconnection scheme designed with the CTC system as its core is as follows: Figure 3 As shown.

[0073] The CTC system shares data with other systems through interfaces that meet railway information exchange technical specifications, such as the "Technical Specification for Information Sharing and Exchange of Railway Information Systems (Q / CR 775-2020)" and the "Interface Specification for Railway Data Service Platform (Q / CR 821-2021)". The interface network employs a redundant design to ensure continuous and reliable data transmission. Data transmission between the interface servers of each system uses the TCP / IP (Transmission Control Protocol / Internet Protocol) protocol, reducing development costs while supporting subsequent enrichment and expansion of upper-layer applications. All system interfaces are interconnected using security devices such as firewalls and network gateways, and network security is ensured through technologies such as authentication, access control, and data encryption.

[0074] Considering Figure 3 All the equipment involved are standard equipment, so they will not be described in detail.

[0075] II. Power outage requests are processed automatically.

[0076] Accurate, rapid, and comprehensive analysis of power outage requests, and the reliable and accurate dissemination of these requests to all lines and stations within the CTC (Center for Traffic Control) system, are fundamental to achieving coordination between train dispatching and power supply dispatching. By automatically analyzing, associating, and reviewing power outage requests, and then automatically drafting dispatching orders and issuing them to relevant units, the system significantly reduces the workload of manual recording, querying, reviewing, and drafting, thus improving operational efficiency. Furthermore, by reducing manual intervention and increasing automatic verification, it enhances information reliability and order accuracy, ensuring operational safety. The automatic processing of power outage requests is as follows: Figure 4 As shown.

[0077] (1) Receiving power outage requests. During construction plans or fault repair operations, the CTC system receives power outage requests submitted by the PDMS, that is, the power outage requests correspond to the planned operation type or fault repair operation type.

[0078] (2) Parsing the power outage application. Key information of the power outage application is extracted by parsing the dedicated communication protocol. If the power outage information is structured data, key information such as the power outage number, power outage time, and power outage area are directly extracted; if it is unstructured text, natural language processing (NLP) technologies such as word segmentation, stop word removal, and context understanding are used to identify and extract key information such as the power outage number, power outage time, and power outage area in the plan. At the same time, the corresponding work information of the power outage application is also parsed out, which is the corresponding construction plan or fault repair work information.

[0079] (3) Linking Power Outage Requests. When a power outage request corresponds to a planned operation type, the scope, time, and outage number of the power outage request are combined with the construction plan uploaded to the TDMS system, and it is determined whether the corresponding outage number is consistent with the parsed outage scope, time, and number. If they are consistent, the information corresponding to the same power outage request is integrated, and redundant and erroneous data are removed to improve the reliability and accuracy of the information for subsequent tracking and unified management. If they are inconsistent, a "Power Outage Request Conflict" alarm is generated and the power outage request is rejected. The dispatcher checks the conflict and restarts the power outage request process. If the power outage request provided by the PDMS is a fault repair operation type, this step is ignored.

[0080] (4) Review power outage application. Check whether the work section in the work information is within the power outage range, whether the work time is within the power outage time, and whether there is no train operation plan within the corresponding time of the power outage range. If any condition is not met, an "approval failed" alarm will be automatically generated and the power outage application will be rejected.

[0081] (5) Drafting power outage dispatch orders. Based on the power outage application information, the system automatically extracts information such as feeder name, substation name, feeder number, power outage card number, and line type involved in the power outage, and automatically drafts power outage dispatch orders.

[0082] (6) Issue power outage dispatch orders. Select all command recipients based on the power outage scope, automatically issue dispatch orders, and track feedback status. If all command recipients agree to the power outage application, the PDMS system will be notified of the approval. Otherwise, an "approval failed" alarm will be generated and the power outage application will be rejected.

[0083] III. Visualization of power supply information and automatic plotting of operation diagrams on the terminal.

[0084] After multiple systems are interconnected, the CTC system can comprehensively collect power supply dispatching data, providing support for the visualization of power supply information. Simultaneously, the CTC system can automatically plot the outage area on the timetable terminal based on the outage information parsed from the aforementioned automatic outage application processing. This facilitates train dispatchers' comprehensive understanding of the system interconnection status and the progress of power outage and restoration operations, while also preventing dispatcher errors and improving decision-making accuracy.

[0085] 1. Visualization of power supply information.

[0086] The power supply information visualization function is implemented in the station map display terminal.

[0087] (1) The connection status with each system can be viewed. The connection status is checked by exchanging heartbeat data packets. A heartbeat data packet is sent every set time (e.g., 10s). If a heartbeat data packet is not received from a certain system for a set number of consecutive times (e.g., 3 times), the connection is considered to be interrupted. An alarm is given by indicating that the CTC system and the network link of that system are disconnected, and a reconnection is automatically initiated.

[0088] (2) Automatic power outage indicator display. Under normal connection conditions, after the CTC system approves the power outage application from the PDMS system, it automatically triggers a command at the power outage time to set a power outage indicator, that is, the power outage status is displayed on the corresponding station and line in the station map display terminal; at the same time, the CTC system also directly obtains the real-time status of the power supply arm from the SCADA system, and automatically associates the power supply arm number with the range of lines and stations affected by the power supply arm, and displays it synchronously on the station map display terminal. When the power outage indicator does not match the actual status of the power supply arm, an alarm "Power outage plan and power supply arm status are inconsistent" is generated, prompting the dispatcher to re-check the information to avoid errors in power outage switching operations or operations beyond the scope.

[0089] 2. The drawing terminal automatically draws the graph.

[0090] To further prevent accidents such as trains entering power outage areas, in addition to displaying power supply information on the station map terminal, technical protection can also be strengthened by prohibiting the generation of train operation plans during power outages and within power outage periods.

[0091] The train timetable terminal can automatically display the timetable. Once the CTC system approves the power outage request, it automatically displays "Preparing for Power Outage" and "Power Outage Completed" prompts on the train timetable. The specific process is as follows: Figure 5 As shown.

[0092] (1) After agreeing to the PDMS power outage application, the “Prepare for power outage” prompt box will be drawn on the operation diagram terminal according to the power outage time and scope obtained from the analysis.

[0093] (2) If there is a train operation plan within the power outage area, the train operation plan will be automatically adjusted for all train lines involved in the power outage area. A new train operation plan will be generated and the dispatcher will be prompted to check and review it. Otherwise, the train operation plan will not be adjusted.

[0094] (3) Once the operation plan is determined, it is prohibited to lay new operation lines within the power outage area.

[0095] (4) If the power outage approval is received from PDMS, continue; if not, determine whether the current time has exceeded the start time of the power outage application. If it has, proceed with the abnormal handling process; otherwise, continue waiting to receive the power outage approval. The abnormal handling process is as follows: ① Generate an alarm message "Power outage approval not received"; ② Feedback the alarm message to the PDMS system; ③ Switch to manual verification of the power outage status. If the power outage has occurred, return the message "Power outage approval received"; if the power outage has not occurred, withdraw the power outage approval, cancel the "Prepare for power outage" prompt, restore the running graph, and end.

[0096] (5) Obtain the status of the power supply arm from SCADA and determine whether the scope of the power outage application is consistent with the actual power outage status of the power supply arm. If they are consistent, draw the "Power outage" prompt box on the operation diagram terminal and replace the "Preparing for power outage" prompt box. The operation diagram terminal drawing process ends. Otherwise, generate a "Power outage error" alarm and report the alarm information to PDMS and SCADA. Stop the operation immediately, verify the situation manually and take countermeasures according to the operation specifications. The operation diagram drawing process ends.

[0097] IV. Collaborative security control technology.

[0098] Collaborative safety control technology is crucial for ensuring the safety and stability of dispatching and command. Its core lies in breaking down the "information silos" formed by traditional independent systems and constructing a system of information sharing, collaborative decision-making, and coordinated control. This involves embedding automated safety verification rules into operational processes to achieve precise detection and joint protection against risks such as power outage errors and trains entering power-deprived areas. To achieve real-time request processing and coordinated control protection across multiple systems, a collaborative safety control process for train dispatching and power supply dispatching is designed as follows: Figure 6 As shown, the process includes five stages: power outage preparation, power outage condition check, power outage operation, safety control, and power restoration. The CTC system, PDMS system, and SCADA system all have corresponding safety control conditions set for the power outage and restoration operations. Figure 6 As shown in the figure, since existing enterprise standards and construction specifications have already made detailed provisions on the safety inspection requirements of PDMS system and SCADA system, this invention takes the CTC side safety control, which lacks corresponding specifications, as the core and sets 10 safety inspection conditions.

[0099] (1) Confirm power outage information: If the power outage application corresponds to the planned operation type, the key information such as the construction number, power outage range, and power outage time in the power outage application and the corresponding construction plan must be consistent; if the power outage application corresponds to the fault repair operation type, the inspection steps are omitted.

[0100] (2) Check the power outage conditions: There are no trains running in the power outage area or the trains have stopped properly; there are no train operation plans in the power outage area or the train operation plans have been adjusted.

[0101] (3) Confirm the scope of the power outage: If the power outage extends to the adjacent dispatch station, the consent of the neighboring bureau's CTC system must be obtained.

[0102] (4) Generate power outage dispatch order: The CTC system sends power outage dispatch orders to all stations (responding locations) within the power outage range and receives "agreement" receipts from each responding location.

[0103] (5) Power outage confirmation: The CTC system receives the power outage approval from the PDMS system and issues it to each commanded location, and receives a "Power outage confirmed" receipt from each commanded location. If the power outage extends to an adjacent dispatch station, a "Power outage confirmed" receipt is received from the neighboring bureau's CTC system.

[0104] (6) Displaying the "Power Outage" notification box: The SCADA system obtains the power supply arm status data and automatically displays the "Power Outage" notification box on the operation diagram terminal. The CTC system combines the analysis results of the power outage application with the real-time status of the power supply arm from the SCADA system to check whether the "Power Outage" notification box has been displayed and prohibits trains from entering the power outage area. For detailed implementation methods, please refer to the previous introduction.

[0105] (7) Prevent trains from entering the work area: After confirming that the power has been cut off, the CTC system checks whether a dispatcher has arranged train routes to the power outage area. If so, the arrangement of routes is prohibited and a system alarm is generated.

[0106] (8) Check the power supply conditions: The key information such as power supply confirmation and power supply range provided by PDMS is consistent with the power outage application, and there are no personnel working in the power outage area.

[0107] (9) Generate power dispatching command: The CTC issues a power dispatching command to each command recipient and receives an "agreement" receipt from each command recipient. If the power dispatching range extends to an adjacent dispatching station, an "agreement" receipt is received from the neighboring CTC system.

[0108] (10) Cancel power outage indication: The SCADA system obtains the power supply arm status data and compares it with the power supply confirmation information. After they are consistent, the “power outage” prompt box drawn on the operation diagram is canceled.

[0109] Since the previous text has already described the various inspection items in detail and introduced their relationship with the automatic processing of power outage applications and the automatic drawing of operation diagram terminals, it will not be repeated here.

[0110] To ensure the widespread applicability of collaborative safety control technology, this process also reserves optional functions for various scenarios of train dispatching. In terms of activation methods, it can be initiated according to the construction plan provided by the TDMS system for normal construction operations; or it can be initiated by an emergency power outage request submitted by the PDMS system for emergency response, ensuring reliable control while achieving rapid response. Regarding scope, it can complete single CTC dispatching station operations or multi-dispatch station collaborative operations. When a work plan is received, the CTC system initiates a power outage inspection request to the neighboring CTC systems. Only after receiving confirmation from all neighboring CTC systems can the PDMS system's power outage and switching command be triggered. In terms of command generation, it can automatically draft various commands such as dispatching and execution commands, and also supports dispatchers manually setting command content and system status after authorization verification.

[0111] The above-mentioned solution provided by the embodiments of the present invention can effectively improve the efficiency and security of dispatching and command. Specifically: (1) Operational efficiency. On the one hand, through multi-source data fusion, intelligent analysis, association, and review of work content are achieved, and dispatch commands are automatically drafted accordingly, ensuring the correctness of commands and avoiding the risks of incorrect route setting, omission, and erroneous power outages and restorations due to human error. On the other hand, the entire process of train dispatching is electronic and automated. In the experimental environment, the average time for power outage and restoration signature and command issuance is reduced by 80.7% compared to the traditional manual mode, which greatly improves the utilization rate of planned maintenance window time. At the same time, all data interaction records and the time taken in each step are traceable, making it possible to continuously optimize the process and further improve efficiency.

[0112] (2) Safety Management. On the one hand, by visualizing power supply information, the power supply information is displayed on the CTC station map display terminal, and the outage time and range are automatically drawn on the operation map, accurately, timely and effectively reminding the dispatcher of the power supply status of each line and station, greatly reducing the number of misoperations caused by the dispatcher due to incorrect or missed recording of power supply information. On the other hand, in the design of the control process, through rigorous processes and strict verification, multiple risk points such as human error, incomplete inspection conditions, incorrect status label settings, and failure to receive receipts are comprehensively prevented and controlled in advance. In the various operation scenarios simulated by the simulation platform, collaborative management and control technology is adopted, which can effectively prevent accidents such as trains entering power-off areas, incorrectly powering off power supply sections, and incorrectly powering off power supply areas.

[0113] (3) Emergency response. By monitoring and integrating data from multiple systems in real time, strong support can be provided for prevention, early intervention, and avoiding impact. In addition, in the event of a sudden failure, the entire construction process can be automatically signed off, eliminating the need for repeated manual communication and information verification, thus significantly shortening the overall failure handling time.

[0114] Overall, the technical solution of this invention changes the traditional isolated and passive operation mode of train dispatching, and provides an effective solution to the problems of low operational efficiency, high safety risks and poor emergency response capabilities faced by existing dispatching. It significantly improves the efficiency and safety of high-speed rail command and dispatch, and is of great significance to the improvement of the dispatching and command level of high-speed railways.

[0115] Through the above description of the embodiments, those skilled in the art can clearly understand that the above embodiments can be implemented by software, or by using software plus necessary general-purpose hardware platforms. Based on this understanding, the technical solutions of the above embodiments can be embodied in the form of a software product, which can be stored in a non-volatile storage medium (such as a CD-ROM, USB flash drive, mobile hard drive, etc.), including several instructions to cause a computer device (such as a personal computer, server, or network device, etc.) to execute the methods described in the various embodiments of the present invention.

[0116] Example 2 This invention provides a collaborative architecture for train dispatching and power supply dispatching based on multi-system data fusion, built on the CTC system, and used to implement the methods described in the foregoing embodiments. It mainly includes: a data acquisition layer, a data governance layer, a fusion analysis layer, and a collaborative application layer. The data acquisition layer is responsible for collecting data, and the data governance layer is responsible for preprocessing the collected data. Both are located in the interface server of the CTC system. The interface server is selected as an edge device for interconnection with various external systems to realize data interaction between the CTC system and various external systems. The external systems include: PDMS system, SCADA system, TDMS system and neighboring bureau CTC system. Among them, the CTC system is a centralized dispatch control system, the PDMS system is an intelligent management system for railway power supply dispatch, the SCADA system is a data acquisition and monitoring control system, and the TDMS system is a transportation dispatch management system. The fusion analysis layer is used to parse power outage requests received from the PDMS system; The collaborative application layer is used to perform one-step or multi-step review of the parsing results based on the type of power outage request, combined with the construction plan from the TDMS system or the fault repair operation information from the PDMS system, to determine whether to approve the power outage request. When approving the power outage request, it visualizes the power supply information on the station map display terminal, combining the real-time status of the power supply arm from the SCADA system, and displays relevant prompt boxes on the operation map terminal based on the parsing results of the power outage request and the real-time status of the power supply arm from the SCADA system. Upon receiving power restoration confirmation information from the PDMS system, it combines PDM... The S system reviews the cancellation operation order application submitted, and after approval, initiates the power restoration process. Furthermore, throughout the entire process from receiving the power outage application to final power restoration, it coordinates with the PDMS and SCADA systems for safety control based on preset safety check conditions. It also interacts with the neighboring CTC system to exchange vehicle status command information, enabling automatic approval of cross-center power outage operations. This automatic approval means that when the power outage operation involves the jurisdiction of a neighboring CTC system, the CTC system sends relevant information to the neighboring CTC system during the review of the power outage application and obtains the neighboring CTC system's consent.

[0117] In practical implementation, the architecture provided by the embodiments of the present invention can be based on the existing CTC test cloud platform, adopting a cloud-edge collaborative distributed design, and combining the above interconnection schemes and key functions to achieve multi-system data integration and fusion analysis. The train dispatching and power supply dispatching collaborative system framework is as follows: Figure 7 As shown, the system comprises a data acquisition layer, a data governance layer, a fusion analysis layer, a collaborative application layer, and an intelligent decision-making layer. Data acquisition and governance are implemented by edge devices, while the functions of the other layers are completed by cloud resources. Through the collaborative work of these layers, the various tasks involved in the CTC system provided in the aforementioned embodiments are accomplished. For ease of understanding, a detailed description of each of the above layers is provided below.

[0118] (1) Data Acquisition Layer. As the foundation of the entire architecture, online monitoring technology is applied to achieve full data acquisition covering CTC internal data, PDMS system, SCADA system, TDMS system, neighboring CTC and other systems through the data interface between CTC system and other systems. Secure data interaction is achieved through security gateways (network isolation devices and firewalls, etc.) and security verification. The data is then classified into basic data, planned data and real-time data for easy subsequent processing.

[0119] (2) Data governance layer. Due to the independent construction of different systems, the problem of data silos is serious. The structure, format and quality of the data are different. Preprocessing is required, including data cleaning, data classification, format conversion and standardization, data reduction and other operations. The data is then managed and stored in a unified manner from the dimensions of catalog, quality and security.

[0120] (3) Fusion Analysis Layer. By integrating data information from different times, spaces, and systems, an intelligent model for scheduling and coordination is trained. By fully utilizing advanced technologies such as big data and artificial intelligence, in addition to parsing power outage requests, it can also analyze and monitor data from multiple systems in real time, thus constructing a panoramic view of high-speed rail dispatch and command.

[0121] (4) Collaborative Application Layer. Provides data modules and service support. It can review power outage applications through trained intelligent models, visualize power supply information and draw prompt boxes related to power outage applications on the station map display terminal after the power outage application is approved, review cancellation operation command applications and restore power supply process after review, and conduct collaborative safety control with PDMS system and SCADA system. In addition, it can continuously collect and process dispatcher work experience, business specifications, industry standards, etc. to form a method library, model library and knowledge base for train power dispatch collaboration, providing support for various collaborative applications, including automatic power outage and restoration signature, multiple safety control, automatic drafting of dispatching orders and automatic drawing of operation map terminal, etc.

[0122] (5) Intelligent Decision-Making Layer. Relying on system-wide data sharing, multi-dimensional information collection, and full-process operation monitoring, a comprehensive management platform with operation management and construction management functions, an emergency response platform with fault identification and emergency dispatch functions, and an auxiliary decision-making platform with intelligent dispatch suggestions and collaborative model optimization functions will be built to jointly construct an integrated, efficient, safe, and intelligent train dispatching collaborative architecture. For example... Figure 7As shown, the following are examples of functional descriptions of the integrated management platform, application handling platform, and auxiliary decision-making platform: (5.1) Integrated management platform: integrated operation management of power dispatch, construction plan management, duty management, and data statistical analysis; (5.2) Application handling platform: automatic fault identification, emergency dispatch command, emergency resource coordination, and fault impact assessment; (5.3) Auxiliary decision-making platform: multi-system correlation analysis, real-time system status monitoring, intelligent dispatch suggestions, and collaborative dispatch model optimization.

[0123] In addition to adopting a cloud-edge collaborative architecture, with the development of technologies such as digital twins, if the computing resources of each system device are relatively sufficient, the "cloud-edge" collaborative mode can be changed to the "cloud-edge-device" collaborative mode. The data acquisition layer is deployed on the device side, and the collected information is directly preliminarily processed and parsed, and then uploaded in a standardized format.

[0124] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims. The information disclosed in the background section is intended only to enhance the understanding of the overall background technology of the present invention and should not be construed as an admission or implication in any way that such information constitutes prior art known to those skilled in the art.

The power outage message box indicates that the drawing process is in the process of automatic drawing in the running drawing terminal. Preventing trains from entering the work area: After confirming that the power is out, the CTC system checks whether any dispatchers are arranging train routes to the power outage area.
