[0002] Urban rail transit often encounters some unpredictable abnormal events in daily operations that affect the normal operation of the system. These abnormal events may cause delays of several trains at the least, or even lead to problems such as passenger delays and operation interruptions at the worst.

[0003] my country's urban rail transit network is gradually expanding, the train running interval is gradually shortening, and the actual operating conditions are becoming more and more complex. Failures that are not handled in time or are handled improperly will have an impact on the line and even the entire network operation, and the difficulty of fault handling management is increasing. Therefore, it is of great significance to improve the efficiency of dispatching and handling and to manage faults from the perspective of the entire line.

[0004] Various operators and enterprises have made some attempts to intelligentize urban rail transit dispatching, but the current handling of fault events mainly relies on the experience of dispatchers, and manual handling is used to handle faults. Faced with the complexity and uncertainty of fault events, dispatchers face heavy workloads and find it difficult to make timely and effective adjustments. In particular, with the gradual formation and expansion of the road network, the intensity and difficulty of dispatchers' work have continued to increase. In addition, the dispatching and handling in the existing technology is mainly based on a single line, and the dispatching and handling does not take into account the passenger flow situation, and the efficiency of dispatching and handling is low. Summary of the invention

[0034] In order to make the technical solutions and advantages in the embodiments of the present application more clearly understood, the exemplary embodiments of the present application are further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than an exhaustive list of all the embodiments. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0035] In the existing urban rail transit dispatching system, most of the dispatching and handling rely on manual work, and the dispatching and handling are mainly based on a single line. In addition, the dispatching and handling do not take into account the passenger flow. Based on this, this application proposes a line network-oriented urban rail intelligent dispatching system, which assists dispatchers to quickly respond to and handle system failures through automated and intelligent means, monitors the impact of failures on the passenger flow of the entire network in real time, coordinates the capacity matching between lines, reduces the impact and influence of failures on the entire road network, and ultimately improves the efficiency of dispatching and handling and improves the quality of operational services.

[0036] Figure 1 For the architecture diagram of the urban rail intelligent dispatching system for the line network provided in the embodiment of the present application, please refer to Figure 1 The architecture shown:

[0037] The urban rail intelligent dispatching system includes a line network intelligent dispatching subsystem 10, a single line intelligent dispatching subsystem 20 and a database 30. There is data flow between the line network intelligent dispatching subsystem 10, the single line intelligent dispatching subsystem 20 and the database 30; specifically, the static data and dynamic data generated by the line network intelligent dispatching subsystem 10 and the single line intelligent dispatching subsystem 20 are stored in the database 30, and the required data are extracted from the database 30.

[0038] In some embodiments of the present application, the line network intelligent scheduling subsystem 10 includes a line network passenger flow monitoring module 11 and a line network capacity adjustment support module 12.

[0039] In a specific implementation, the basic data logic of the urban rail intelligent dispatching system for the line network of the embodiment of the present application is:

[0040] The single-line intelligent dispatching subsystem 20 outputs the operation diagram and fault handling status to the line network intelligent dispatching subsystem 10, and the line network intelligent dispatching subsystem 10 outputs capacity recommendations and passenger flow warning information to the single-line intelligent dispatching subsystem 20; further, the line network passenger flow monitoring module 11 of the line network intelligent dispatching subsystem 10 outputs passenger flow indicators to the line network capacity adjustment support module 12 based on the information from the single-line intelligent dispatching subsystem 20, and the line network capacity adjustment support module 12 outputs information to the single-line intelligent dispatching subsystem 20 based on the information from the line network passenger flow monitoring module 11.

[0041] In the operation of urban rail transit, it is divided into at least a normal operation stage and a fault stage; in specific implementation, when the line network passenger flow monitoring module 11 does not receive any fault information, that is, when the urban rail transit is in the normal operation stage, the AFC data is collected and updated in real time, and the passenger flow is predicted based on the AFC data. When the passenger flow exceeds a predetermined threshold (expressed in this application as the normal stage passenger flow threshold), a relevant warning is issued (expressed in this application as the normal stage warning information).

[0042] Specifically, in some embodiments of the present application, during the normal operation phase of urban rail transit, the line network passenger flow monitoring system will collect and update AFC data in real time, and predict passenger flow indicators such as real-time entry and exit, transfer in different directions, number of people waiting at stations, and number of people stranded on platforms through passenger flow deduction, and monitor the passenger flow of the entire network. When the passenger flow exceeds the passenger flow of the same period in the past or the established normal stage passenger flow threshold, the line network passenger flow monitoring system will give normal stage warning information.

[0043] Based on this, the detection automation based on single line and line network is realized in the intelligent dispatching of urban rail transit, and the coordination and matching of inter-line capacity is realized through the passenger flow simulation, passenger flow warning, capacity adjustment suggestion and other functions of the line network intelligent dispatching subsystem 10.

[0044] In a specific implementation, when a fault occurs in the operation of urban rail transit, the fault information is immediately transmitted to the single-line intelligent dispatching subsystem 20, and simultaneously uploaded to the line network intelligent dispatching subsystem 10 through the database 30. Specifically, in the embodiment of the present application, the entire fault handling is divided into three stages: the initial stage of fault handling, the continuous stage of fault, and the fault recovery stage.

[0045] In this embodiment, different processing methods are used according to the characteristics and handling requirements of different stages: in the early stage of fault handling, it is necessary to control the scene as soon as possible; in the continuous stage of the fault, the handling and operation adjustment of the faulty line are the main focus; after the fault is restored, it is necessary to quickly restore the operating order and evacuate the backlog of passengers.

[0046] Based on this, in addition to the single-line intelligent dispatching subsystem 20, the present application also includes a line network intelligent dispatching subsystem 10; through the mutual cooperation of the single-line intelligent dispatching subsystem 20 and the line network intelligent dispatching subsystem 10, a rapid response to single-line fault handling is achieved based on fault handling process prompts and dynamic adjustment functions of the operation diagram.

[0047] Specifically, the interactions between the subsystems and modules in the urban rail intelligent dispatching system in the three stages of fault handling are as follows:

[0048] S100, initial stage of troubleshooting:

[0049] S101. When the single-line intelligent dispatching subsystem 20 receives the initial fault information reported on site, it issues the first fault handling instruction; specifically, the initial fault information reported on site will be uploaded to the database 30 for storage at the same time; specifically, the single-line intelligent dispatching subsystem 20 will immediately detain the vehicle after receiving the initial fault information, and issue the first step fault handling instruction for the initial fault information, that is, the first fault handling instruction, to the site.

[0050] S102. When the single-line intelligent dispatching subsystem 20 receives the initial fault information reported on site, it uploads the first fault handling instruction execution information and the initial fault information to the line network passenger flow monitoring module 11; further, the line network passenger flow monitoring module 11 monitors the passenger flow changes during the execution of the first fault handling instruction. If the passenger flow changes exceed the passenger flow threshold of the fault stage, a fault stage warning information is issued; specifically, the line network intelligent dispatching subsystem 10 will continue to pay attention to the fault handling situation and the fluctuation of passenger flow during the fault handling period. If the passenger flow changes little, the line network intelligent dispatching subsystem 10 will not do anything for the time being; if the passenger flow changes greatly and exceeds the established passenger flow threshold of the fault stage, the line network passenger flow monitoring module 11 will give a corresponding warning.

[0051] Based on this, the line network intelligent dispatching subsystem 10 of the present application includes a line network passenger flow monitoring module 11 and a line network capacity adjustment support module 12. Through functions such as passenger flow simulation, passenger flow warning, and capacity adjustment suggestions, it realizes the coordination and matching of inter-line capacity, reduces the impact of single-line failures on the operation and passenger flow of the entire network, and ultimately improves the dispatching efficiency and improves the quality of operational services.

[0052] S103.1. If the single-line intelligent dispatching subsystem 20 receives the first fault handling success information, it enters the fault recovery phase S300.

[0053] S103.2. If the single-line intelligent dispatching subsystem 20 receives the first fault handling failure information, it enters the fault continuation stage S200.

[0054] S200, fault continuation stage:

[0055] S201. If the single-line intelligent dispatching subsystem 20 receives information that the first fault handling has failed, a second fault handling instruction is issued; specifically, after receiving information that the on-site fault has not been restored, the single-line intelligent dispatching subsystem 20 will immediately issue a second fault handling instruction to the site for a second fault handling.

[0056] S202. The single-line intelligent dispatching subsystem 20 updates the dynamic adjustment operation diagram according to the first fault handling failure information to support the train operation during the execution of the second fault handling instruction; specifically, the existing operation plan is adjusted according to the details of the faulty turnout, and a new dynamic adjustment operation diagram is generated to support the train operation during the fault continuation stage, and is sent to the site after confirmation by the dispatcher; optionally, as the fault handling time continues, the dynamic adjustment operation diagram is iterated in a cycle of 30 minutes until the fault is completely restored; in the specific implementation, during this period, each time an operation diagram is updated for the faulty line, the operation diagram is immediately uploaded to the line network intelligent dispatching subsystem 10.

[0057] Based on this, during the fault continuation stage, the single-line fault handling rapid response is achieved through the dynamic adjustment function of the operation diagram of the single-line intelligent dispatching subsystem 20.

[0058] S203, the line network passenger flow monitoring module 11 outputs the predicted passenger flow indicators for the fault continuation stage according to the updated dynamically adjusted operation diagram; specifically, every time the line network intelligent dispatching subsystem 10 receives a new operation diagram, the line network passenger flow monitoring module 11 is immediately updated and deduces the future spatiotemporal changes of the passenger flow of the entire network based on the new operation diagram, predicts the future short-term passenger flow situation, gives corresponding passenger flow indicators (such as real-time entry and exit, transfers in different directions, number of people waiting at the station, number of people stranded on the platform, etc.) and gives corresponding warnings.

[0059] Based on this, during the fault continuation stage, the capacity adjustment information of the adjacent lines of the fault line is output by predicting the passenger flow indicators, that is, the passenger flow simulation and passenger flow warning functions of the line network intelligent scheduling subsystem 10 are used to achieve coordination and matching of the inter-line capacity.

[0060] S204. The line network capacity adjustment support module 12 outputs the capacity adjustment information of the adjacent lines of the fault line according to the predicted passenger flow index during the fault duration stage; specifically, the line network capacity adjustment support module 12 combines the passenger flow forecast given by the line network passenger flow monitoring module 11, considers the passenger flow fluctuation degree and the single-line capacity (through capacity, number of spare vehicles, etc.), gives capacity adjustment suggestions for the adjacent lines of the fault line, and adjusts the capacity supply in the corresponding period; optionally, the passenger flow organization and control strategy can be issued at the same time when necessary.

[0061] Based on this, during the stage where the fault persists, the capacity adjustment information of the adjacent lines of the fault line and the passenger flow organization and control strategy information during the stage where the fault persists are output by predicting passenger flow indicators. The capacity adjustment suggestions and passenger flow organization and control strategy functions of the line network intelligent scheduling subsystem 10 are used to achieve coordination and matching of capacity between lines, and after the fault is restored, it is possible to quickly restore operating order and evacuate backlog passengers.

[0062] S205. If the adjacent line is equipped with an intelligent single-line intelligent dispatching function, the urban rail intelligent dispatching system can automatically generate a dynamic adjustment operation diagram based on the capacity recommendations given by the line network intelligent dispatching subsystem 10, and directly issue it for execution after confirmation by the dispatcher; if the adjacent line is not equipped with a single-line intelligent dispatching function, the dispatcher will handle it manually.

[0063] S206. If the single-line intelligent dispatching subsystem 20 receives the second fault handling success information, it enters the fault recovery phase S300.

[0064] S300, Fault recovery phase:

[0065] In a specific implementation, when the first fault handling instruction is executed successfully or the fault is completely restored after the second fault handling instruction is executed, the line transportation capacity is restored and the fault handling enters the fault recovery stage.

[0066] S301. If the single-line intelligent dispatching subsystem 20 receives the first fault handling success information or the second fault handling success information, it generates a recovery phase operation diagram and uploads it to the line network intelligent dispatching subsystem 10. The line network intelligent dispatching subsystem 10 performs post-fault recovery operation scheduling according to the recovery phase operation diagram. Specifically, the single-line intelligent dispatching subsystem 20 receives the fault recovery information and immediately generates an operation diagram for the operation recovery phase. The operation diagram temporarily does not consider the passenger flow and adjusts the train operation plan with the goal of quickly returning to the diagram. The generated operation diagram will be directly uploaded to the line network intelligent dispatching subsystem 10.

[0067] S302. The single-line intelligent dispatching subsystem 20 generates a fault recovery phase operation diagram based on the fast return diagram, and uploads the fault recovery phase operation diagram to the line network passenger flow monitoring module 11. The line network passenger flow monitoring module 11 outputs the predicted passenger flow indicators for the fault recovery phase according to the recovery phase operation diagram. Specifically, after the line network intelligent dispatching subsystem 10 receives the fault recovery information and the updated operation diagram, the line network passenger flow monitoring module 11 will immediately and quickly deduce the passenger flow of the entire network according to the new operation diagram, re-predict future short-term passenger flow changes, and provide relevant passenger flow indicators.

[0068] Based on this, after the fault is restored, with the goal of quickly restoring operational order and evacuating backlogged passengers, an operation diagram for the fault recovery phase based on rapid mapping was generated, and the capacity adjustment information of each line in the entire network was output. That is, the passenger flow of the entire network was quickly deduced according to the new operation diagram, and future short-term passenger flow changes were re-predicted, thus achieving the final operational control in the recovery phase.

[0069] S303, the line network capacity adjustment support module 12 outputs the capacity adjustment information of each line in the entire network according to the predicted passenger flow indicators in the fault recovery phase; specifically, the line network capacity adjustment support system will give capacity adjustment suggestions for each line in the entire network based on future short-term passenger flow data and the transportation capacity of each line (including the faulty line), and send it to the relevant lines; optionally, it can also send passenger flow organization and control strategies at the same time when necessary.

[0070] Based on this, during the fault recovery phase, rapid response to single-line fault handling is achieved through the dynamic adjustment function of the operating diagram of the single-line intelligent dispatching subsystem 20, and inter-line capacity coordination and matching is achieved through the capacity adjustment suggestions and passenger flow organization and control strategy functions of the line network intelligent dispatching subsystem 10.

[0071] S304. Each relevant line automatically or manually adjusts the operation plan according to the capacity adjustment suggestion given by the line network intelligent dispatching subsystem 10. After receiving the capacity adjustment plan, the faulty line will regenerate an operation diagram for the operation recovery phase. At this time, the operation diagram will quickly adjust the operation plan to match the changes in passenger flow, and finally display it on the front end of the single-line intelligent dispatching subsystem 20 for the dispatcher to confirm. After the dispatcher confirms, the line will be issued for execution.

[0072] In summary, the urban rail intelligent dispatching system proposed in this application includes a single-line intelligent dispatching subsystem 20, a line network intelligent dispatching subsystem 10 (including a line network passenger flow monitoring module 11, a line network capacity adjustment support module 12) and a database 30. In the event of a fault, the single-line intelligent dispatching subsystem 20 will immediately handle the fault and upload the handling situation to the line network passenger flow monitoring module 11. The line network passenger flow monitoring module 11 monitors the driving and passenger flow changes of the entire line in real time, and gives capacity recommendations for the faulty line and related lines in stages according to the changes in passenger flow. Each line then adjusts the driving plan of the line according to the capacity recommendations.

[0073] Furthermore, the present application takes a turnout failure on a line as an example to further illustrate the above content; Figure 2 For a schematic diagram of the fault handling process of the urban rail intelligent dispatching system provided in the embodiment of this application, please refer to Figure 2 :

[0074] S1: At the initial stage of fault handling, the switch fault information is reported on site to the single-line intelligent dispatching subsystem 20 and the database 30.

[0075] S1.1: The single-line intelligent dispatching subsystem 20 of the faulty line immediately detains the train upon receiving the fault information, and issues dispatching instructions to the site to operate the single switch. At the same time, the fault handling situation (including fault information) is uploaded to the line network passenger flow monitoring module 11.

[0076] S1.2: The line network intelligent dispatching subsystem 10 will continue to pay attention to the fault handling situation and the fluctuation of passenger flow during the fault handling period. If the passenger flow changes slightly, the line network intelligent dispatching subsystem 10 will not do anything for the time being; if the passenger flow changes significantly and exceeds the established threshold, the line network passenger flow monitoring module 11 will give a corresponding warning.

[0077] S2: If the single switch on site fails, the fault handling will enter the fault continuation stage.

[0078] S2.1: After receiving the information that the fault has not been restored on site, the single-line intelligent dispatching subsystem 20 will immediately issue a manual turnout instruction to the site, and adjust the existing operation plan according to the details of the fault turnout, generate a new dynamic adjustment operation diagram to support the train operation during the fault continuation stage, and send it to the site after confirmation by the dispatcher. As the fault handling time continues, the dynamic adjustment operation diagram will be iterated in a cycle of 30 minutes until the fault is completely restored. During this period, every time a running diagram is updated on the fault line, the running diagram will be immediately uploaded to the line network intelligent dispatching subsystem 10.

[0079] S2.2: Whenever the line network intelligent dispatching subsystem 10 receives a new operation diagram, the line network passenger flow monitoring module 11 is immediately updated and deduces the future spatiotemporal changes of the passenger flow of the entire network based on the new operation diagram, predicts the future short-term passenger flow, and gives corresponding passenger flow indicators (such as real-time entry and exit, transfers in different directions, the number of people waiting at the station, the number of people stranded on the platform, etc.) and gives corresponding warnings.

[0080] S2.3: The line network capacity adjustment support module 12 combines the passenger flow forecast given by the line network passenger flow monitoring module 11, considers the passenger flow fluctuation degree and the single line capacity (through capacity, number of spare vehicles, etc.), gives capacity adjustment suggestions for the adjacent lines of the fault line, and adjusts the capacity supply in the corresponding period. If necessary, the passenger flow organization and control strategy needs to be issued at the same time.

[0081] S2.4: If the adjacent line is equipped with an intelligent single-line intelligent dispatching function, the urban rail intelligent dispatching system can automatically generate a dynamic adjustment operation diagram based on the capacity recommendations given by the line network intelligent dispatching subsystem 10, and directly issue it for execution after confirmation by the dispatcher; if the adjacent line is not equipped with a single-line intelligent dispatching function, the dispatcher will handle it manually.

[0082] S3: When the switch is successfully switched or the switch is fully restored after manual operation, the line transportation capacity is restored and the fault handling enters the fault recovery stage.

[0083] S3.1: The single-line intelligent dispatching subsystem 20 receives the fault recovery information and immediately generates an operation diagram for the operation recovery phase. The operation diagram temporarily does not consider passenger flow and adjusts the train operation plan with the goal of rapid restoration. The generated operation diagram will be directly uploaded to the line network intelligent dispatching subsystem 10.

[0084] S3.2: After the line network intelligent dispatching subsystem 10 receives the fault recovery information and the updated operation diagram, the line network passenger flow monitoring module 11 will immediately quickly deduce the passenger flow of the entire network according to the new operation diagram, re-predict future short-term passenger flow changes, and provide relevant passenger flow indicators.

[0085] S3.3: The line network capacity adjustment support module 12 will give capacity adjustment suggestions for all lines in the entire network based on the future short-term passenger flow data and the transportation capacity of each line (including the faulty line), and send them to the relevant lines. If necessary, the passenger flow organization and control strategy needs to be sent at the same time.

[0086] S3.4: Each relevant line automatically or manually adjusts the operation plan according to the capacity adjustment suggestions given by the line network. After receiving the capacity adjustment plan, the faulty line will regenerate an operation diagram for the operation recovery phase. At this time, the operation diagram will quickly adjust the operation plan to match the changes in passenger flow, and finally display it at the front end of the single-line intelligent dispatching subsystem 20 for the dispatcher to confirm. After the dispatcher confirms, the line will be issued for execution.
