and (3) OBC: vehicle-mounted controller

OC: target controller
The invention provides an autonomous running system of interconnected collinear and crossline running trains, which can support the collinear or crossline running of the trains provided with different manufacturer vehicle-mounted controllers (OBCs) on one or more rail traffic lines provided with different trackside signal devices, and comprises the following components: the system comprises a vehicle-mounted controller OBC, a target controller OC, an automatic train monitoring system ATS and an interconnection and intercommunication interface adapter module.
When a train carries out cross-line operation, the vehicle-mounted controller OBC establishes communication with the automatic train monitoring system ATS and the target controller OC of both sides of the interconnection through the interconnection and intercommunication interface adaptation module, through the ATS double-vision handover overlapping area, the vehicle-mounted controller OBC receives and executes an operation command issued by the automatic train monitoring system ATS, and the vehicle-mounted controller OBC acquires driving resources of the target controller OC through the interconnection and intercommunication interface adaptation module and provides train state information for the automatic train monitoring system ATS through the interconnection and intercommunication interface adaptation module. Therefore, the application and the release of the running resources of the train to the adjacent line OC are automatically carried out according to the operation command of the dispatching personnel or the train running plan, and the OBC (on-board controller) automatically calculates the movement authorization to complete the cross-line running of the train.
The line target controller OC interacts with the adjacent line target controller OC through the interconnection and intercommunication interface adaptation module, shares the running resource state of a handover overlapping area, replaces a degraded train to complete cross-line route handling, and ensures the safe operation of the cross-line train on the contact line.
When trains equipped with different factory vehicle-mounted controllers OBC run on an interconnection line in a collinear tracking mode, the target controller OC receives registration requests from the different train vehicle-mounted controllers OBC through the interconnection interface adaptation module to manage each train in the administrative region. Specifically, the OC receives requests of each train applying and releasing the driving resources of the line in the jurisdiction area, feeds back the train state and the driving resource state in the jurisdiction area by the OBC, and sends the tie line handover overlap area trackside state information to the automatic train monitoring system ATS for displaying.
Therefore, the co-line and cross-line interconnection and intercommunication are realized on the basis of vehicle-to-vehicle communication, and the purposes of economy and applicability, resource sharing, coordinated command, advanced technology, sustainable development and the like are achieved.
Example one
Referring to fig. 1, in an autonomous train operation system for interconnecting, communicating, collinear and crossline operation, a left area of a handover boundary is a home OC control area OC1 equipped with a home trackside signal device, a right area is a friend control area OC2 equipped with a friend trackside signal device, a train 1 equipped with a left-side on-board controller runs crossline from a left-side OC1 control area to a friend control area OC2 through a handover overlapping area, and a train 2 equipped with a right-side on-board controller runs crossline from a right-side to a left-side from a right-side friend control area OC2 to a home OC control area OC1 through a handover overlapping area. The corresponding lines are provided with an automatic train monitoring system ATS and a target controller OC, each train is provided with an on-board controller OBC, and the joint boundaries of the two control areas are provided with bidirectional virtual signal machines respectively.
When a train 1 with a self-home vehicle-mounted controller on the left side carries out cross-line operation, a vehicle-mounted controller OBC of the train 1 is communicated with an ATS and a target controller OC of a train automatic monitoring system and a target controller of both sides of interconnection and intercommunication, through an ATS double-vision handover overlapping area, the train 1 autonomously applies and releases driving resources to an adjacent line OC2 according to a scheduling personnel operation command or a train operation plan, and the OBC autonomously calculates the movement authorization to complete the cross-line tracking operation of the train 1. And communication is established between the two party target controllers OC, the running resource state of the transfer overlapping area is shared, the degraded train is replaced to finish cross-line route handling, and the safe operation of the cross-line train on the contact line is ensured.
The OBC receives and executes operation commands issued by dispatchers through ATS of different manufacturers through the interconnection and intercommunication interface adaptation module, acquires OC driving resources of different signal manufacturers and provides train state information for the ATS of the different manufacturers, and the OC target controller interacts with the OC adjacent line through the interconnection and intercommunication interface adaptation module to share the state of the driving resources in the handover overlapping area.
The interconnection and intercommunication interface adaptation module is developed on a safety computer platform, various interfaces of a signal system can be adapted and converted into internal unified types through configuration to be processed, the signal system interfaces of the configuration types are provided outwards, and the module can reach the safety level of SIL4 by adopting various safety verification modes.
The method comprises the steps that an online timetable editor is used for editing and issuing an overline operation plan timetable, an ATS splits timetable information into single train operation plans and issues the single train operation plans to on-board controllers (OBCs) of all trains which are interconnected and intercommunicated, and the OBCs autonomously trigger overline route entry according to loaded timetable information.
And a virtual signal machine is arranged at the joint boundary of the two control areas, so that the handling of the ground ATS cross-line departure route and the receiving route is realized.
When the train operates in a degraded mode due to faults of vehicle-mounted equipment or communication equipment, the OC performs cross-route handling on the degraded train, and the operation safety of the degraded train is guaranteed.
The degraded train is manually handled by the ground ATS across the route. Taking the train 1 as an example, the current position of the train is located in OC1, when the cross-line route to the OC2 control area is transacted by dragging the train 1 to a target platform or a target signal machine in the OC2 control area, the cross-line route path comprises a handover overlapping area and a track section of an adjacent control area OC2, the ATS sends a downgrade route setting command to a target controller OC1 in the control area to which the train belongs, and the OC1 replaces the downgrade train to apply for driving resources to the adjacent control area OC2, so that the transaction of the cross-line route of the train is completed. The adjacent control area OC2 handles the route for receiving the vehicle according to the request of the driving resource, and the local control area OC1 handles the route for departure after the signal for receiving the vehicle is opened.
The cancellation of the cross-line operation of the degraded train is handled by the departure party in a unified way, and the cross-line safe operation of the degraded train is ensured. Still taking train 1 as an example, when a departure party cancels the cross-line operation, a dispatcher issues an entry cancellation command to an OC1 of the control area through an ATS human-computer interface, when an OC1 judgment condition is met, departure entry driving resources are released, departure signals are closed, departure entry is unlocked, and an OC2 of an adjacent control area judges that departure signals are closed, pickup entry driving resources are released, pickup signals are closed, and pickup entry is unlocked; when the receiver needs to cancel the cross-line receiving operation, the control area OC2 belonging to the receiver sends a request for canceling the cross-line operation to the control area OC1 belonging to the sender, after the control area OC1 belonging to the sender meets the judgment condition, the departure route driving resource is released, the departure signal is closed, the departure route is unlocked, the adjacent control area OC2 judges that the departure signal is closed, the receiving route driving resource is released, the receiving signal is closed, and the receiving route is unlocked.
Example two
As shown in fig. 2, the train 1 equipped with the own-vehicle-mounted controller and the train 2 equipped with the friend-business-vehicle-mounted controller operate in line at the own-control-area OC1 equipped with the own-trackside signal device on the left side at the same time, or the train 3 equipped with the own-vehicle-mounted controller and the train 4 equipped with the friend-business-vehicle-mounted controller operate in line at the friend-control-area OC2 equipped with the friend-business-vehicle-mounted signal device on the right side at the same time.
Taking train 1 and train 2 as an example, when trains equipped with different factory vehicle-mounted controllers OBC run in a collinear tracking mode in the same control area OC1 on an interconnection line, a target controller OC1 receives registration requests from different train vehicle-mounted controllers OBC to manage each train in a jurisdiction area, OC1 receives requests of each train in the jurisdiction area for applying and releasing running resources of the line, feeds back train states and running resource states in the jurisdiction area to each train, and sends state information of trackside equipment in a tie line handover overlapping area to an ATS for displaying.
The train autonomous operation system described in the above embodiment of the present invention can support the collinear or cross-line operation of trains equipped with different manufacturer on-board controllers OBCs on one or more rail transit lines equipped with different trackside signal devices, so as to achieve the purposes of resource sharing and sustainable development on the basis of reducing operation cost and improving operation efficiency, and meanwhile, meet the expectations of network command center for managing the whole regional rail transit network and networked operation, and make a contribution to intelligent transportation.
