[0002] With the continuous expansion of rail transit networks and the acceleration of modernization, the complexity of rail transit systems has increased significantly. Traditional experimental and testing methods are no longer sufficient to meet the requirements for efficient and safe operation of modern rail transit systems. Rail transit systems encompass multiple complex subsystems, which are highly coupled and have complex interdependencies. Therefore, the design, operation, and maintenance processes of the system are becoming increasingly complex, requiring efficient collaboration between subsystems to ensure the safety and operational efficiency of the entire system.

[0003] In the research and development and testing of rail transit systems, different experimental platforms focus on their respective specific subsystems or research directions. In practical applications, it is difficult to fully simulate or predict certain fault scenarios in a single experimental platform environment.

[0004] Faced with ever-increasing traffic volume and increasingly complex operating environments, establishing cross-regional and interdisciplinary collaborative research platforms has become an inevitable choice. How to improve the linkage efficiency and execution accuracy of multi-location experimental platforms is an urgent problem to be solved by researchers in this field. Summary of the Invention

[0026] Figure 1 This invention provides an architecture diagram of a multi-location experimental platform linkage system based on group train operation control. This embodiment is applicable to situations where data sharing among experimental platforms located in multiple regions is achieved efficiently. This multi-location experimental platform linkage system based on group train operation control can be implemented in both hardware and software. Different experimental platforms within this system can be configured on servers with communication and computing capabilities in multiple regions. Figure 1 As shown, the system includes:

[0027] The field experimental platform 110 is used to provide actual operation scenarios of real group trains and to acquire actual operation data in the actual operation control process of real group trains in the actual operation scenarios.

[0028] Specifically, the field experimental platform 110 may include a real station with actual group train operation conditions. By deploying a real group train operation scenario on the station, the platform controls the real group train to operate in the actual operation scenario and acquires actual operation data during the actual operation. For example, the actual operation data can be acquired through field sensing terminals deployed on the real group train and the platform. The actual operation data includes at least signal maintenance machine operation data, train speed and density, and track conditions.

[0029] The theoretical simulation experimental platform 120 is used to provide simulation scenarios for the theoretical deduction of digital group trains and to acquire theoretical simulation data of the operation control process of digital group trains in the simulation scenarios.

[0030] Specifically, the theoretical simulation experimental platform 120 refers to a platform for theoretically deriving the operation control of train groups. For example, a digital train group is obtained by simulating a real train group, and the digital train group is simulated based on the actual operation data of the real train group. Based on the simulation results, other scenarios are simulated to provide a theoretical basis for the actual operation of the real train group.

[0031] In the theoretical simulation experimental platform 120, the digital group train is controlled to simulate the actual operation scenario of the real group train, as well as other operation scenarios, and the data obtained during the operation is used as theoretical simulation data.

[0032] The model simulation experimental platform 130 is used to provide a simulation scenario for the simulated operation of a group of train models and to acquire simulation data during the operation control process of the group of train models in the simulation scenario.

[0033] Specifically, the simulation experiment platform refers to a platform for simulating the operation and control of a train group model. For example, a corresponding train group model is created based on a real train group. The train group model is modeled according to the scale of the real train group, and the track model on which the train group model runs is also simulated based on the real track on which the real train group runs.

[0034] In the model simulation experimental platform 130, the control group train model simulates the actual operation of the real group train and other operation scenarios to obtain the data acquired during the operation, which is the simulation data.

[0035] Among them, the field experimental platform 110, the theoretical simulation experimental platform 120, and the model simulation experimental platform 130 are located in different regions.

[0036] Since different regions have different development capabilities, it is necessary to combine data from experimental platforms with different development capabilities.

[0037] Specifically, in the research and development and testing of rail transit systems, different experimental platforms focus on their respective specific subsystems or research directions. In practical applications, some fault scenarios are difficult to be fully simulated or predicted in a single experimental platform environment. Therefore, the field experimental platform 110, the theoretical simulation experimental platform 120, and the model simulation experimental platform 130 are located in different regions.

[0038] A secure data channel is established between the field experimental platform 110, the theoretical simulation experimental platform 120, and the model simulation experimental platform 130 to facilitate data transfer between all experimental platforms, enabling any experimental platform to obtain data from the other two experimental platforms.

[0039] Data acquired by any experimental platform can be sent to other experimental platforms via a secure data channel, enabling any experimental platform to access data from all experimental platforms. For example, the field experimental platform 110 can acquire theoretical simulation data from the theoretical simulation experimental platform 120 and simulation data from the model simulation experimental platform 130 via the secure data channel; the theoretical simulation experimental platform 120 can acquire actual operating data from the field experimental platform 110 and simulation data from the model simulation experimental platform 130 via the secure data channel; and the model simulation experimental platform 130 can acquire actual operating data from the field experimental platform 110 and theoretical simulation data from the theoretical simulation experimental platform 120 via the secure data channel.

[0040] For example, the data transmission order between the three experimental platforms can be determined according to the specific requirements of the train operation control scenario, and is not limited here.

[0041] Data is transmitted in real time to the three experimental platforms via a secure data channel, enabling data linkage and resource sharing. This supports the analysis and simulation of complex data such as train operation data, achieving more efficient analysis and more accurate results through distributed computing and data processing. Data linkage facilitates data transfer, computation, and simulation between the three experimental platforms, enabling real-time data sharing, collaborative processing, and comprehensive analysis.

[0042] Scene linkage modules are established in the field experimental platform 110, the theoretical simulation experimental platform 120, and the model simulation experimental platform 130, respectively. The scene linkage modules are used to synchronously display the data of all experimental platforms.

[0043] The scene linkage module is used to recreate real remote scheduling and remote vehicle dispatch scenarios, and realize synchronous display, fault injection and scene reproduction of the three experimental platforms.

[0044] Specifically, a scenario linkage module is deployed in each experimental platform. The scenario linkage module acquires data from all experimental platforms and displays the data from each experimental platform synchronously in all experimental platforms. This enables synchronous control of the data from all experimental platforms in each experimental platform, and better realizes the ability to share data in real time, process collaboratively, and perform comprehensive analysis.

[0045] Different experimental platforms can focus on their respective strengths in specific subsystems or research directions. Through the collaborative mechanism of the three-location experimental platforms, research results and data can be integrated and shared, significantly improving overall R&D efficiency and the comprehensiveness of testing. The three-location collaborative experimental platform can fully utilize the resource and technological advantages of experimental platforms in each location to jointly conduct simulations and predictions of complex fault scenarios. This model provides a more in-depth and comprehensive guarantee for the safety and reliability of rail transit systems. The three-location collaborative experimental platform model has significant advantages in the R&D and testing of rail transit systems. It not only improves the synergy and efficiency of research but also strengthens the fault detection and prediction capabilities in complex systems, ensuring that problems discovered in experiments can be promptly verified and optimized in actual operating systems. The construction of this collaborative platform not only promotes multidisciplinary and multi-field cooperation but also lays a solid foundation for the safe, efficient, and intelligent development of future rail transit systems.

[0046] The solution in this invention combines actual operational data, theoretical simulation data, and analog data through data and scenario linkage between experimental platforms in different geographical locations. This achieves information sharing and complementary advantages, realizing cross-regional data resource sharing and joint technical analysis and integration. This not only accelerates the feedback speed of experimental results and improves experimental execution efficiency, but also quickly reflects problems discovered in the experiment into actual operation, improving the reliability of experimental results and further verifying and improving system design, thereby effectively enhancing the safety and reliability of the rail transit system. Through real-time data sharing and synchronous scenario linkage, different experimental platforms can collaborate efficiently, significantly improving the efficiency and accuracy of experimental execution. The use of secure data channels ensures the security of data transmission, effectively preventing unauthorized access and data tampering, providing security for cross-regional experiments.

[0047] Figure 2 This is an architecture diagram of a scene linkage module in a multi-location experimental platform linkage system based on group train operation control, provided by an embodiment of the present invention. This embodiment further refines the scene linkage module in the above embodiment. For example... Figure 2 As shown, the scene linkage module includes:

[0048] The scene linkage module includes a digital twin unit 201, which is used to generate a digital twin based on the data of the target train in each experimental platform, to obtain a digital twin model of the target train corresponding to each experimental platform, and to synchronously display the digital twin models of the target train corresponding to all experimental platforms.

[0049] The target train is identified from the group of trains. There can be one or at least two target trains; the number of target trains is not limited. Digital twins are created based on the data of the target train in each experimental platform, resulting in a digital twin model of the target train in each experimental platform. For example, a first target train digital twin model is obtained based on the actual operating data of the target train in field experimental platform 110; a second target train digital twin model is obtained based on the theoretical simulation data of the target train in theoretical simulation experimental platform 120; and a third target train digital twin model is obtained based on the simulation data of the target train in model simulation experimental platform 130. The first, second, and third target train digital twin models are simultaneously displayed in each experimental platform, allowing the display of the same train's operating results across different platforms on each platform, thereby improving the processing efficiency of each experimental platform in controlling the operation of the group of trains.

[0050] For example, digital twins can be used to recreate the scene of a target train and simulate future operations in order to plan corresponding train operation strategies.

[0051] In this system, the digital twin unit 201 is also used to perform target simulation fault tests on the target train digital twin model corresponding to each experimental platform, obtain the target simulation fault test results corresponding to each experimental platform, and analyze the target simulation fault test results corresponding to all experimental platforms to obtain the final test results of the target simulation fault.

[0052] Among them, the target simulated fault is determined based on the possible fault information determined by the simulated future operation. The target simulated fault test is carried out on the target train digital twin model corresponding to each experimental platform to obtain the target simulated fault test results of each experimental platform. The target simulated fault test results of each platform are comprehensively analyzed to obtain the final test result of the target simulated fault.

[0053] For example, in each experimental platform, target simulation fault tests are simultaneously performed on the first target train digital twin model, the second target train digital twin model, and the third target train digital twin model to obtain the first target simulation fault test result corresponding to the first target train digital twin model, the second target simulation fault test result corresponding to the second target train digital twin model, and the third target simulation fault test result corresponding to the third target train digital twin model. The consistency of the first target simulation fault test result, the second target simulation fault test result, and the third target simulation fault test result is determined. If they are the same, the final test result is determined to be the first target simulation fault test result; if they are inconsistent, the target train digital twin model and experimental platform corresponding to the different target simulation fault test results are determined, and the experimental platform and the corresponding target train digital twin model are analyzed in detail to obtain the final test result of the target simulation fault.

[0054] By conducting test analysis on the target train digital twin models in all experimental platforms to simulate faults, the completeness of the final test results and the scenario coverage of the target fault simulation were improved, thereby ensuring the safety and stability of train operation control.

[0055] In this system, the digital twin unit 201 is also used to generate a fault database based on the final test results of the target simulated fault and the handling information of historical faults, so as to guide the operation control of real group trains based on the fault database; wherein, the fault database includes at least multiple candidate faults corresponding to fault phenomena, fault equipment types, fault history occurrence information, fault analysis results and maintenance guidance schemes.

[0056] The handling information for historical faults is determined based on actual operational data, while the final test results for the target simulated faults are determined based on the simulation test results of the digital twin unit 201. Statistics are compiled on both the target simulated faults and historical faults, and the relevant information for each fault is organized to generate a fault database. This allows for appropriate handling based on the fault database when a fault is encountered during the operation control of a real train group in the field experimental platform 110, and the database is optimized based on the handling results. The candidate faults in the fault database include both target simulated faults and historical faults.

[0057] The digital twin unit 201 simulates target simulation failures in the target train digital twin model. It simulates track conditions, train speed and density, communication delays, etc. by creating a simulation environment. In the simulation environment, various target simulation failures are introduced to test the fault tolerance capability of the rail transit system and evaluate the performance of the rail transit system in the face of failures. By adjusting the simulation parameters, various complex and extreme operating scenarios are simulated to comprehensively evaluate the performance and reliability of the rail transit system under extreme conditions.

[0058] The digital twin unit 201 establishes a fault database to facilitate fault simulation and maintenance. It records in detail various fault information of railway vehicles and trackside equipment, including the time, location, equipment type, and fault phenomenon. Faults are classified according to their nature and impact. Through in-depth mining and analysis of fault data, the causes and patterns of fault occurrence are identified. Based on the fault analysis results, maintenance guidance plans are generated to provide maintenance personnel with fast and accurate fault location and maintenance methods.

[0059] In this system, the scene linkage module includes a real-time video monitoring unit 202, which provides operation monitoring videos of all experimental platforms; the scene linkage module also includes a large screen display unit 203, which synchronously displays operation monitoring videos of at least all experimental platforms.

[0060] The real-time video monitoring unit 202 uses high-definition cameras deployed on various experimental platforms to capture real-time video streams of key areas in the platform, providing visual support for remote monitoring and operation. For example, the key area in the field experimental platform 110 is the running track area of ​​the real group train, the key area in the model simulation experimental platform 130 is the running track area of ​​the group train model, and the key area in the theoretical simulation experimental platform 120 is the simulation operation interface of the digital group train.

[0061] Combined with the large screen display unit 203, real-time video, analog data and digital twin model views are displayed synchronously, enhancing the visualization and understandability of information; using a high-precision digital twin model, the state and behavior of physical equipment are simulated and mapped, enabling precise control of remote scheduling and operation.

[0062] Through high-definition cameras, digital twin units 201, and real-time data transmission technology, experimental platforms in different locations can share experimental data and monitoring information at the same time, thereby achieving efficient and accurate collaborative experimental operations.

[0063] For example, the digital twin unit 201 uses 3D simulation technology to reproduce historical events or simulate future operations, and displays the scene on the large-screen display unit 203 for training or strategy planning. The 3D model reflects the actual physical layout, equipment configuration, and connection methods. Based on the 3D model, different operating scenarios are set, including normal operating states and various potential fault states. In the simulated data center environment, faults are introduced, and 3D simulation technology is used to reproduce the fault occurrence process, including fault detection, alarms, impact range, and system recovery. By simulating different fault scenarios, the performance of the data center under various conditions is analyzed, performance bottlenecks and potential risk points are identified, and strategies for optimizing data center design and operation are proposed based on the simulation results to improve system reliability and efficiency.

[0064] In this system, the scene linkage module includes a remote desktop unit 204, which is used to provide remote control of the operation interfaces of the other two experimental platforms from any experimental platform.

[0065] The scene linkage module includes: a real-time video monitoring unit 202, a large screen display unit 203, a digital twin unit 201, and a remote desktop unit 204; the remote desktop unit 204 uses remote desktop services provided by a third-party service provider to realize remote operation of the operation interface of the computer systems in the three locations, so as to realize remote control of the operation interface of the other two experimental platforms from any experimental platform.

[0066] By utilizing digital twin technology, complex fault scenarios can be simulated to test the system's fault tolerance under extreme conditions and promptly identify potential performance bottlenecks. This not only improves system safety but also enhances the reliability of the entire rail transit system. The digital twin unit 201, through 3D simulation technology, can accurately reproduce historical events or simulate future operations, providing strong technical support for experimentation, strategy planning, and personnel training. This function not only improves the system's emergency response capabilities but also provides crucial data for the optimized design of rail transit systems. The system also generates a fault database and rapid maintenance guidance: through the establishment of a fault database and in-depth analysis of fault data, the system can generate detailed maintenance guidance plans, helping maintenance personnel quickly and accurately locate and repair faults, thereby significantly improving the efficiency and accuracy of fault handling.

[0067] The solution of this invention, by further explaining the scene linkage module, improves the completeness of scene linkage between multiple experimental platforms, thereby enhancing the collaborative capability of multiple experimental platforms.

[0068] Figure 3This is an architecture diagram of another multi-location experimental platform linkage system based on group train operation control provided by an embodiment of the present invention. This embodiment further refines the field experimental platform 110 in the above embodiment. For example... Figure 3 As shown, the system further includes:

[0069] In this system, the field experimental platform 110 includes a sensing center 101, a data center server 102, and a data center industrial control computer 103.

[0070] The sensing center 101 is used to acquire raw sensing data through on-site sensing terminals deployed in the actual operation scenario of real train groups, and send the raw sensing data to the data center server 102; the data center server 102 is used to parse and process the raw sensing data to obtain actual operation data, and send the actual operation data to the data center industrial control computer 103; the data center industrial control computer 103 is used to send the received actual operation data to other experimental platforms through the data forwarding engine.

[0071] The sensing center 101 is connected to the data center server 102 via an HTTP reporting interface. The data center server 102 transmits the data calculated by the sensing center 101 to the data center industrial control computer 103 through a secure data channel.

[0072] Data center server 102 provides a standard HTTP reporting interface. The sensing center 101 reports the basic vehicle data from the field laboratory sensing terminal and signal maintenance machine to the data center server 102 in real time via the HTTP interface. The data center server 102 quickly processes the data sent by the sensing center 101 and transmits it to the data center industrial control computer 103 through a secure data channel. The data forwarding engine in the data center industrial control computer 103 quickly sends the data from the data center to other experimental platforms, such as the model simulation experimental platform 130 or the theoretical simulation experimental platform 120, through a secure network channel.

[0073] In this system, the data center industrial control computer 103 sends the actual operating data to the model simulation experiment platform 130 through a secure data channel, and the model simulation experiment platform 130 processes the actual operating data to obtain simulation data.

[0074] The model simulation experiment platform 130 sends simulation data and actual operation data to the theoretical simulation experiment platform 120 through a secure data channel. The theoretical simulation experiment platform 120 processes the simulation data to obtain theoretical simulation data.

[0075] The theoretical simulation experimental platform 120 sends theoretical simulation data and simulation data to the data center industrial control computer 103 in the field experimental platform 110 through a secure data channel.

[0076] The data forwarding engine in the data center industrial control computer 103 quickly sends the data from the data center to the model simulation experiment platform 130 through a secure network channel. The terminal interaction system deployed in the model simulation experiment platform 130 directly inputs the data into the simulation system and transmits the generated simulation data to the theoretical simulation experiment platform 120 in real time through a secure network channel. The terminal interaction system deployed in the theoretical simulation experiment platform 120 directly inputs the data into the simulation system and transmits the generated simulation data to the data industrial control computer of the field experiment platform 110 in real time through a secure network channel.

[0077] By achieving closed-loop data transmission between the three experimental platforms, the integrity of data transmission and the safety and stability of the rail transit system for train operation control are ensured.

[0078] In this system, the secure data channel uses an encryption algorithm to encrypt the data to be transmitted.

[0079] Encryption technology is used to protect data transmission during data linkage, preventing unauthorized access and tampering.

[0080] The technical solution of this invention improves the integrity and accuracy of actual operating data by perfecting the data transmission process of the equipment in the field experimental platform, avoiding errors in actual operating data caused by errors in data collection by the field equipment; and by explaining the data linkage between the field experimental platform, the model simulation experimental platform 130 and the theoretical simulation experimental platform, it improves the integrity of data linkage between multiple experimental platforms and improves the efficiency of rail transit system development.

[0083] S420, based on the scene linkage module, synchronously displays data from all experimental platforms in the field experimental platform, theoretical simulation experimental platform, and model simulation experimental platform.

[0084] The on-site experimental platform is used to provide actual operating scenarios of real train groups and acquire actual operating data of the train group operation control process in the actual operating scenarios; the theoretical simulation experimental platform is used to provide simulation scenarios of theoretical deduction of digital train groups and acquire theoretical simulation data of the train group operation control process in the simulation scenarios; the model simulation experimental platform is used to provide simulation scenarios of the simulated operation of train group models and acquire simulation data of the train group operation control process in the simulation scenarios; the on-site experimental platform, the theoretical simulation experimental platform, and the model simulation experimental platform are located in different regions.

[0085] The solution of this invention combines actual operational data, theoretical simulation data, and analog data through data and scenario linkage between experimental platforms in different geographical locations. This achieves information sharing and complementary advantages, realizing cross-regional data resource sharing and joint technical analysis and integration. This not only accelerates the feedback speed of experimental results and improves experimental execution efficiency, but also quickly reflects problems discovered in the experiment into actual operation, improving the reliability of experimental results and further verifying and improving system design, thereby effectively enhancing the safety and reliability of the rail transit system. Through real-time data sharing and synchronous scenario linkage, different experimental platforms can collaborate efficiently, significantly improving the efficiency and accuracy of experimental execution. The use of secure data channels ensures the security of data transmission, effectively preventing unauthorized access and data tampering, providing security for cross-regional experiments.
