[0029] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Combine the following Figure 1-Figure 9 The present invention describes a cluster scheduling system and method for cross-line operations.

[0031] Figure 1 FIG. 1 is a structural diagram of a cluster scheduling system for cross-line operation according to an exemplary embodiment. Figure 1 As shown, in an exemplary embodiment, the cluster dispatching system for cross-line operation includes a central-level cluster dispatching system, multiple line-level dispatching systems and multiple station-level dispatching systems, wherein the line-level dispatching system is connected to the central-level cluster dispatching system, and the station-level dispatching system is connected to the corresponding line-level dispatching system; The central-level cluster dispatching system is used to monitor and control the central-level line cluster; The line-level dispatching system is used to monitor and control a single line; The station-level dispatching system is used to perform train control at the single-line station level.

[0032] In the embodiment of the present invention, the cluster dispatching system for cross-line operation is divided into a three-layer structure of center level, line level and station level.

[0033] like Figure 2 As shown, Figure 2 The physical structure diagram of the cross-line operation cluster scheduling system shown in the embodiment of the present invention is as follows: Figure 3 As shown, Figure 3The software structure diagram of the detailed cross-line operation cluster scheduling system shown in the embodiment of the present invention.

[0034] The central-level cluster dispatching system consists of cluster application servers, database servers, central dispatching workstations, and operation diagram compilation workstations. It mainly completes the monitoring and control functions of the central-level line cluster, that is, monitoring and controlling multiple lines. At the same time, the normal driving dispatching command of the line cluster is completed by the central-level cluster dispatching system. The line cluster is a cluster composed of all lines.

[0035] The line-level dispatching system consists of application servers, second database servers, line dispatching workstations, operation diagram compilation workstations and other equipment, and mainly completes the monitoring and control functions of a single line. For the scenario where the line-level dispatching system and the center-level cluster dispatching system use the same integrator, the line-level dispatching system and the center-level cluster dispatching system can be combined. One line corresponds to one line-level dispatching system, and the line-level dispatching systems of different lines can be from the same integrator or different integrators.

[0036] The station-level dispatching system consists of station extensions, on-site workstations and other equipment, and is mainly used to complete train operation control and equipment control at the single-line station level.

[0037] When the center-level cluster dispatching system and the line-level dispatching system are from the same integrator, the center-level cluster dispatching system is directly connected to the station-level dispatching system through an internal protocol. At this time, the center-level dispatching system and the line-level dispatching system are merged.

[0038] When the center-level cluster dispatching system and the line-level dispatching system are from different integrators, it is difficult to unify the internal protocol of the dispatching system. Therefore, the line interface machine is added for access. By unifying the interface protocol at the interface machine level, the access problems caused by the protocol differences of different integrators are reduced, and cluster management of dispatching systems of different integrators is realized. The interface of the line interface machine uses the TCP / IP protocol as the underlying message interface.

[0039] In the interface relationship between the center-level cluster scheduling system and the line-level scheduling system, the center-level cluster scheduling system is the client and the line-level scheduling system is the server. The real-time information and non-real-time information in the interface establish their own socket links respectively, listening to the ports defined by both parties. Both parties send heartbeat information regularly. When the heartbeat information of the other party is not received within the specified time, it is regarded as a socket interruption, and the current connection should be closed and a new connection should be reinitialized.

[0040] The information exchange between the center-level cluster dispatching system and the line-level dispatching system is completed by sending messages to each other. The messages are encapsulated in a uniformly specified information frame, and the information frame format of each integrator is consistent. The data in the information frame includes: length, time, line number, equipment identification, command sequence number, type, version number and information body. The information body transmits status or data information such as heartbeat messages, information request messages, overall equipment status messages, equipment status change messages, train messages, and operation diagram messages; transmits control command messages such as route commands, turnout commands, signal machine commands and other special commands; transmits cluster dispatching and line dispatching control rights messages; transmits special safety command messages, etc.

[0041] When a task needs to send multiple packets of the same type and function code, no new packet will be sent until all such packets have been sent.

[0042] The protocol clearly defines message types, device types, device status, line numbers, station codes, command numbers and IDs, train identification information, etc. It also fully considers the differences that may arise from system differences among subsequent integrators and makes relevant reservations for the protocol.

[0043] In an embodiment of the present invention, by setting up a center-level cluster dispatching system, the line-level dispatching system is connected to the center-level cluster dispatching system to achieve comprehensive information monitoring and control of the line cluster, thereby improving the efficiency of line-to-line coordination and solving the problem of inadequate network management functions. At the same time, through a unified cross-line cluster dispatching system, the difficulty of personnel reuse is reduced and the cost of personnel training is reduced. The cross-line cluster dispatching system provided by the present invention can support the cluster control of the line-level dispatching system of the same integrator, and also supports the cluster control of the line-level dispatching systems of different integrators. By opening different interfaces, the coordinated access, control, monitoring and management of each line-level dispatching system in the line cluster are completed.

[0044] In an exemplary embodiment of the present invention, the central cluster scheduling system is specifically used for: Realize at least one of the following: coordinated control between lines, authority management of cluster lines, and coordinated adjustment of cross-line and transfer connections between lines.

[0045] In the embodiment of the present invention, in addition to realizing the single-line scheduling adjustment, the central-level cluster scheduling system is also provided with an inter-line cross-line and transfer connection collaborative adjustment module, an inter-line collaborative control module and a cluster line authority management module. The inter-line cross-line and transfer connection collaborative adjustment module realizes the collaborative adjustment of transfers between different lines. The inter-line collaborative control module realizes the collaborative adjustment between the same lines. Cluster line authority management realizes the management of the scheduling management authority of each line-level scheduling system and station-level scheduling system, such as opening and closing relevant authorities. Through the various modules set up, a dispatcher can achieve unified control and adjustment functions of multi-line hub stations and cross-line hub stations.

[0046] Figure 4 A schematic diagram of inter-line collaborative adjustment of a cross-line operation cluster scheduling system provided by an embodiment of the present invention, Figure 5 Schematic diagram of dynamic adjustment of train operation according to an embodiment of the present invention. Figure 6 A schematic diagram of generating a scheduling strategy in an embodiment of the present invention.

[0047] like Figure 4 As shown, the central cluster dispatching system monitors the running status of trains in the line cluster, and at the same time, monitors the faults of each line, and handles the faults when a fault is detected. Specifically, when a line fails, based on the fault information and impact provided by the external system, the line, vehicle, personnel, energy and other resource conditions of each line in the line cluster are used as restricted conditions, and the decision variables, objective functions and constraints are set through the train operation dynamic adjustment model, and then iterative optimization is performed to obtain the train operation adjustment strategy, and the obtained train operation adjustment strategy is evaluated and verified. When the verification fails, a new train operation adjustment strategy is solved again based on the train operation dynamic adjustment model. When the verification passes, the train operation adjustment result is obtained. Based on the train operation adjustment results, under transfer conditions, coordinated adjustments such as coordinated skipping and adjustment of train faults on this line, coordinated skipping and adjustment of neighboring lines due to faults on this line, coordinated adjustment of the last train delay on this line to neighboring lines, coordinated adjustment of the last train delay on adjacent lines, and coordinated release of emergency information can be achieved; under interconnection conditions, coordinated stop adjustments of neighboring line train delays, coordinated adjustment of neighboring line train suspension on this line, coordinated adjustment of train delays on this line to neighboring lines, coordinated adjustment of train suspension on this line, coordinated adjustment of train delays on this line to neighboring lines, and coordinated release of emergency information can be achieved.

[0048] like Figure 5 As shown in the figure, the diagram preparation workstation set up in the central cluster dispatching system prepares the train diagram based on the planned passenger flow. At the same time, the train diagram is dynamically adjusted based on the predicted passenger flow. During the adjustment, abnormal events such as line failures are captured, and digital emergency plans are determined based on the abnormal events. Then, adjustment strategies are generated, compared, and the optimal adjustment strategy is selected and executed through the TIAS system.

[0049] like Figure 6 As shown, when a fault occurs, the fault information is obtained through the intelligent operation and maintenance system or the fault information reporting system, and the fault information includes the fault location, fault cause, handling method, handling time, etc. The acquired fault information is sent to the knowledge reasoning machine, and the knowledge reasoning machine calls the information in the dispatching expert knowledge base. The dispatching expert knowledge base forms the corresponding relationship between dispatching rules, fault data and dispatching strategies based on the emergency fault handling plan, dispatching log, etc. The knowledge reasoning machine determines the dispatching strategy based on the acquired fault information, the dispatching expert knowledge base and the train operation plan in the dynamic operation diagram module, forms the corresponding dispatching execution plan based on the determined dispatching strategy, and sends the dispatching execution plan to the command execution module for execution after the dispatcher confirms it.

[0050] Through the solution provided in this embodiment, the central-level cluster dispatching system pushes the operation adjustment strategy of the relevant lines (transfers, cross-line) within the line cluster, so as to ensure the operation order, quickly evacuate the stranded passengers on the platform, and reduce the impact of the fault on the road network operation under the existing line resource conditions.

[0051] In an exemplary embodiment of the present invention, the central cluster scheduling system is further specifically used for: At least one of the following is achieved: pre-loading planned operation information, generating actual operation information, and compiling multi-line operation information.

[0052] In the embodiment of the present invention, the train operation diagram / timetable includes: a basic operation diagram / timetable, a planned operation diagram / timetable and an actual operation diagram / timetable.

[0053] The basic operation diagram / timetable is a kind of original data for the central-level cluster dispatching system to command the train operation. The basic operation diagram / timetable is divided into various basic train operation diagrams / timetables for weekdays, holidays, different seasons, different operating hours of the day, temporary events, etc. Correspondingly, the planned operation diagram / timetable and the actual operation diagram / timetable are the data for the planned and actual commanded train operation of the central-level cluster dispatching system, respectively.

[0054] The central cluster scheduling system provides the function of setting the planned operation information to be loaded in advance, such as the planned operation diagram, so as to correctly and automatically load the planned operation information for the day before starting the operation. The preset loading plan mode includes preset by single day and preset by time period.

[0055] The central-level cluster dispatching system automatically generates actual operation information, such as the actual operation diagram / timetable, based on the actual operation of the train. The planned operation diagram / timetable and the actual operation diagram are displayed simultaneously with different background colors and lines, with the current time as the dividing line. As time goes by, the actual operation diagram covers the planned operation diagram / timetable.

[0056] The center-level cluster dispatching system also realizes the automatic compilation of operation diagrams, adds the function of compiling multi-line operation information, and realizes the basic information management of multi-line operation diagrams, operation route management, operation plan management, cross-line operation management, operation diagram adjustment and inspection, and operation diagram indicator statistics.

[0057] There are two methods for compiling basic operation diagrams / timetables: automatic compilation and manual compilation. Figure 7 FIG. 1 is a schematic diagram of automatically compiling multi-line operation information in an embodiment of the present invention. Figure 7 As shown, input the conditions and constraints that meet the actual operation needs, such as interval operation time constraints, departure interval constraints, stop time constraints, etc., and automatically compile the operation diagram through the operation diagram compilation mechanism.

[0058] Manual preparation means that planners can manually prepare operation diagrams according to actual needs. The manual operation functions provided by the central cluster scheduling system include: modifying service numbers, copying / pasting, deleting service numbers, shifting, adding train numbers, deleting train numbers, modifying train numbers, connecting, disconnecting, etc.

[0059] In addition to the main line plan, the center-level cluster dispatching system also supports the preparation of shift plans, car wash / standby plans, and automatic shunting plans.

[0060] In an exemplary embodiment of the present invention, the central cluster scheduling system is further specifically used for: Realize at least one of route control, equipment control and train control of multiple lines.

[0061] In the embodiment of the present invention, the central-level cluster dispatching system has line equipment and train control functions, including: Route control: automatic / manual triggering of routes, handling / cancelling routes, manual release of routes, route changes, route conflict checks, etc.; Control of signal machines, turnouts, sections and other equipment: blocking / unblocking of signal machines / turnouts / sections; signal reappearance / special opening, special opening with speed limit, etc.; single turnout operation, single turnout locking / single release, forced turnout; section release, section removal, manual locking / unlocking of protected sections, axle counter reset / pre-reset; Train control: adjustment methods such as turning on / off automatic adjustment, turning on / off equal interval adjustment; manual adjustments such as detaining trains, skipping stops, early departure, setting stop time / operating level, etc.; setting train attributes such as first-carriage train / planned train / manual train; temporary speed limit; train speed limit; rain and snow mode; issuing instructions such as wake-up, sleep, and clearing passengers; remote control functions such as remote door opening and closing, remote setting / relieving emergency brakes, and remote restart.

[0062] In an exemplary embodiment of the present invention, the central cluster scheduling system is further specifically used for: After starting the function of adjusting based on the train operation plan, the train section running time and platform stop time are adjusted according to the deviation from the train operation plan and the train operation plan.

[0063] In an embodiment of the present invention, the central-level cluster dispatching system provides a function of enabling / disabling adjustments based on the train operation plan. After the function is manually enabled, the central-level cluster dispatching system automatically adjusts the train section operation time and platform stop time according to the train plan deviation and the train operation plan (operation plan diagram).

[0064] After all application servers are restarted, the automatic function of making adjustments based on the train operation plan is not enabled by default and needs to be enabled manually.

[0065] The means of automatic adjustment of train operation include: changing the train interval operation level, changing the train stop time, when automatic adjustment is performed, adjusting the operation level has higher priority than adjusting the stop time, and when the train is early or late within a certain time range, the planned adjustment function takes effect, otherwise the planned adjustment function is invalid; when the platform has manually set stop time and manually set operation level, the central-level cluster dispatching system does not perform automatic adjustment, but executes according to the manual setting; for unscheduled trains, ATS does not perform automatic adjustment.

[0066] In an exemplary embodiment of the present invention, the central cluster scheduling system is further specifically used for: Acquire train operation status information, equipment status information and train location information of multiple lines, and record and store the train operation status information and equipment status information; The train is identified and tracked based on the train location information.

[0067] In the embodiment of the present invention, the central cluster dispatching system obtains the train operation status information, signal equipment status information and train location information provided by the ATP / ATO system and interlocking equipment through a redundant network. The main function of the ATP system (Automatic Train Protection) is to monitor the speed of the train and keep it at a safe running interval, thereby preventing train collision and derailment; the main function of the ATO system (Automatic Train Operation) is to control the automatic operation of the train and the precise parking of the station, and to achieve energy saving. The central cluster dispatching system tracks trains through the section occupancy status or the train position information reported by the ZC. Specifically, for CBTC (Communication Based Train Control System) trains, the train position is tracked through the train position information sent by the ZC. For non-CBTC trains, the train position is tracked through the physical section occupancy information reported by the interlocking system. The central cluster dispatching system automatically completes and realizes the continuous tracking of trains on the main line and in the train window of the depot / parking lot. At the same time, the central cluster dispatching system can automatically switch the tracking mode according to the operation level of the train.

[0068] Unlike conventional systems that only support single-line monitoring and control, the central-level cluster dispatching system supports access to station-level dispatching systems of different lines and manufacturers, and ensures smooth access to each line through a unified interface protocol. The central-level cluster dispatching system issues equipment and train operation control instructions for each line, receives equipment and train operation status information for each line, and performs unified display methods and operation procedures.

[0069] like Figure 8 As shown, Figure 8 The figure is a schematic diagram of the interface data flow between the center-level cluster dispatching system and the station-level dispatching system in an embodiment of the present invention.

[0070] The central cluster dispatching system can record and save the train operation status and equipment working status, and can perform statistics and analysis. Including: parking accuracy report, including train set, platform, parking error; full load rate report, including train set, train number, platform, full load rate; train travel speed report, including train set, train travel speed; train interval parking time report, including train set, train station, logical section and parking time; train station stop time report, including train set, platform, door opening response time, door opening duration, train departure time, total station stop time; post-station reversal time report, including train set, station, reversal rail name, reversal time, arrival reversal rail time, reversal rail stay time, reversal time, total reversal time; plan deviation report, including train set, platform, arrival time (planned / actual), arrival deviation, departure time (planned / actual), departure deviation, station stop time (planned / actual), station stop deviation; platform departure interval report: including station, platform, train Train number, train set, departure time, departure interval; section operation time report: including train number, train set, section, section operation time; fulfillment rate report, including date and fulfillment rate; punctuality rate report, including date, departure punctuality rate, arrival punctuality rate, operation punctuality rate; train mileage report, including train set, total running distance, running distance since last monthly maintenance, running distance since last scheduled maintenance, running distance since last frame maintenance, running distance since last factory maintenance; daily operation report, including train number, driver number, station, platform, train set, arrival time, departure time; driver mileage report, including driver number, date, daily mileage, historical cumulative mileage; dispatch message report, including dispatcher account, time, message content; reserve vehicle report, including the location and reserve status of train sets and trains; train maintenance status report, including the location and maintenance status of train sets and trains.

[0071] All kinds of statistics and index calculations can be printed and output in the form of reports. All stored data can be output in Excel format. The central-level cluster dispatching system provides the function of querying the online train operation information of the entire line, which can query the actual operation information of all online trains, display the stations and sections where a certain train or all running trains are currently located, and provide early and late status prompts for train operation. At the same time, it can list the train location status of a certain station or all stations, and can display the train stop, train detention, skip stop, manual stop time, train running direction, train running mode and other information.

[0072] The center-level cluster dispatching system provides historical data query function, which includes alarm data, operation records, playback data, daily planned operation diagram / timetable, and shift plan data.

[0073] In an exemplary embodiment of the present invention, the cluster scheduling system for cross-line operation also includes a basic scheduling system; The basic dispatching system is used to implement an emergency station control mode after the central-level cluster dispatching system, the line-level dispatching system and the station-level dispatching system fail; The station-level dispatching system is also used to implement a station control mode after a failure of the line-level dispatching system.

[0074] In the embodiment of the present invention, three control modes are provided to meet different needs: central control, station control, and emergency station control. At the same time, a control mode conversion function is also provided, which can be initiated by the central dispatching workstation or the local workstation of the station.

[0075] In the embodiment of the present invention, a basic dispatching system is additionally configured. When the center-level cluster dispatching system, the line-level dispatching system, and the station-level dispatching system all fail, the emergency station control mode is entered. In the emergency station control mode, the basic dispatching system realizes the train control of a single station. When the line-level dispatching system fails, the station control mode is realized. In the station control mode, the station-level dispatching system realizes the functions of the line-level dispatching system. In the central control mode, the line-level dispatching system monitors and controls a single line.

[0076] In the embodiment of the present invention, the dispatching workstation has the function of managing the dispatching control area, and can allocate the dispatching control authority to the line concentration area. The local workstation has the function of allocating control authority to the non-concentrated station by handing over and receiving the control area.

[0077] In an exemplary embodiment of the present invention, the center-level cluster dispatching system, the line-level dispatching system and the station-level dispatching system are also used to respectively monitor the operating status of equipment and provide fault alarms.

[0078] In the embodiment of the present invention, there are perfect self-diagnosis and equipment operation status monitoring and fault alarm functions. The operation status and fault alarm of the equipment can be monitored through the workstation. The alarm is displayed in different colors according to its severity and the status of confirmation and processing, and prompt information is given. All alarm records are displayed in the form of a list in the alarm window, and are displayed in different colors according to the level of the alarm.

[0079] The print content of the fault alarm can be printed and previewed, and can be flexibly saved in text file format, but the content of the event and alarm cannot be changed.

[0080] Based on the operation records stored in the database, the center-level cluster dispatching system and the line-level dispatching system provide playback functions for station status, train details, alarm information, and operation records on the system's maintenance workstation. The playback data includes: station status data, operation record data, and alarm record data. The application server is responsible for the collection and storage of playback data. Users can make comprehensive judgments on faults based on alarms and playback to improve operational handling efficiency.

[0081] In an exemplary embodiment of the present invention, the central-level cluster scheduling system is also used to configure system parameters; The line-level scheduling system is also used to update parameters based on configured system parameters.

[0082] In the embodiment of the present invention, system parameters can be configured on the maintenance workstation of the center-level cluster scheduling system. The operator can modify the system parameters, and after the modification is completed, it is necessary to save and upload the database. The application server will automatically download the latest configuration parameters and update them.

[0083] The same user can only log in on one device at a time. The central cluster dispatching system provides a password modification function. User information can also be managed on the maintenance workstation of the central cluster dispatching system. User information includes user number, user name, administrator, and user type. The control authority of user information can be set, that is, on which devices the user can log in. User types include dispatcher, maintainer, planner, dispatcher, and dispatcher. The system can add, delete, modify, and clear user information.
