Technical Field

[0001] This invention relates to the field of train signal control technology, and in particular to a train operation control method and device based on turnaround trains. Background Technology

[0002] The Communication Based Train Control System (CBTC) uses communication between onboard and ground equipment to establish corresponding departure routes for trains, thereby enabling train departure and operation control.

[0003] However, in the existing CBTC system, when there is a train turning back on the departure route of the train waiting to leave the station, the train must completely leave the turning-back section (which overlaps with the departure route of the train waiting to leave the station) before the train running in the forward direction (i.e. the train waiting to leave the station) can leave the station. This results in a long departure time and significantly reduces operational efficiency.

[0043] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0044] In the existing CBTC system, if there is a train turning back on the departure route of the train waiting to depart (i.e. the target train), the target train can only proceed to the departure route after the train turning back has completely left the turn-back section. If the distance between the platform where the target train is located and the turn-back section is too long, the target train will enter the departure route only after the turn-back train has completed its turn, which will significantly reduce operational efficiency.

[0045] This invention allocates route resources to trains through a vehicle-to-vehicle communication and train control system in rail transit, enabling refined resource allocation and higher train resource utilization. When there are trains that need to cut in or turn back on the departure route, the original departure route can be split into separate routes. Even if the original departure route includes reverse locking, trains can still depart from the station, improving the tracking interval. After the train cuts in and turns back, the interval between the departing train and the train that cuts in is significantly shortened, improving turnaround efficiency and thus improving operational efficiency.

[0046] Figure 1 This is a flowchart illustrating the train operation control method based on turnaround trains provided by the present invention, as shown below. Figure 1 As shown, the present invention provides a train operation control method based on turnaround trains, comprising:

[0047] Step 101: Obtain the turnaround stopping area information of the turnaround train, wherein the turnaround stopping area information is the stopping area information corresponding to when the turnaround train stops on the track to be traveled by the target train during the turnaround process; the target train is the train waiting to depart in the train station.

[0048] Based on the vehicle-to-vehicle communication and train control system, this invention provides a section locking method based on virtual resources. The systems involved include the existing Resource Controller (RC), Automatic Train Supervision (ATS), and Intelligent Vehicle On-Board Controller (IVOC) in vehicle-to-vehicle communication. The IVOC is further divided into various subsystems, including Intelligent Train Protection (ITP) and Intelligent Train Operation (ITO).

[0049] In this invention, the RC system architecture execution layer is consistent with the fully electronic interlocking system. The RC communicates with the OC (Object Controller), which collects trackside information and sends it to the RC. The RC sends commands to the OC to control trackside equipment. Simultaneously, the RC interacts with the IVOC and ATS. The RC sends station information to the ATS and receives commands from the ATS (such as partial path locking, path locking, etc.). The RC also sends communication vehicle and faulty vehicle information, as well as station information, to the IVOC and receives resource requisition and release commands from the IVOC. In this invention, the Zone Controller (ZC) function in the CBTC system is assigned to the RC and IVOC respectively. The RC is responsible for resource management and train management, while the IVOC is responsible for resource matching and calculating Movement Authority (MA).

[0050] In this invention, the resource locking and resource allocation functions of the RC are refined. The ATS issues a resource path locking command. After the RC receives the command and locks the resource, it sends the resource information to the IVOC. After the IVOC requisitions the resource, it obtains information on other lines (such as platform screen doors, emergency buttons, signal lights, etc.) to facilitate the forward extension of the train.

[0051] Furthermore, in this invention, the direction of travel of the target train is taken as the down direction, and the direction of travel of the turnaround train before turning back is taken as the up direction. Before entering the down direction track (i.e., the track to be traveled on), the turnaround train travels on the approach track. Through the switches on the approach track, the turnaround train enters the track to be traveled. In this invention, the turnaround path of the turnaround train on the track to be traveled can be planned based on the real-time position of the turnaround train on the approach track. Then, based on this turnaround path, the parking area information of the turnaround train on the track to be traveled, i.e., the turnaround parking area information, can be obtained.

[0052] Step 102: Based on the turnaround parking area information, determine the target travel area information of the target train on the track to be traveled, wherein the target area corresponding to the target travel area information is set between the parking area corresponding to the turnaround parking area information and the train platform.

[0053] In this invention, the departure route information of the target train and the turnaround parking area information have overlapping track areas. By splitting the departure route information into two corresponding track segments, and then setting corresponding locks on these two track segments, the target train can also travel from the train platform to the corresponding area based on the locked resources while the turnaround train is traveling to the parking position on the waiting track. In this invention, after the turnaround parking area information of the turnaround train is determined, the corresponding track area is locked based on this turnaround parking area information. Accordingly, the turnaround parking area information is used as a dividing point (such as a signal light on the side of the turnaround parking area closer to the train station) to split the departure route into two parts, one part including the turnaround parking area information and the other part being the target travel area information of the target train on the waiting track.

[0054] Step 103: Using the turnaround parking area information, control the turnaround train to travel to the corresponding parking area on the track to be traveled, and using the target travel area information, control the target train to travel to the target area.

[0055] In this invention, based on the turnaround parking area information and the target travel area information, the corresponding track sections on the track to be traveled are locked, thereby allowing the corresponding trains to travel in their respective track sections. In this invention, the target train extends forward according to the target travel area information through movement authorization, while maintaining a safe distance, thus reducing the distance between it and the turnaround train, without waiting for the turnaround train to clear its route before processing the departure route.

[0056] The train operation control method based on turnaround trains provided by this invention obtains the turnaround stopping area information of the turnaround train, determines the target travel area information of the train waiting to depart in the train station on the track to be traveled, and then controls the turnaround train to travel to the corresponding stopping area on the track to be traveled by using the turnaround stopping area information, and controls the train waiting to depart in the train station to travel to the target area by using the target travel area information, so that the train no longer needs to wait for the turnaround train to completely leave the turnaround section, thus improving the efficiency of train departure and operation.

[0057] Based on the above embodiments, obtaining the turnaround stopping area information of the turnaround train includes:

[0058] Obtain the position information and travel speed information of the turnaround train when it is on the approach track at the current moment, wherein the approach track is the track on which the turnaround train was located before it traveled to the track to be traveled;

[0059] Based on the location information, a target turnout on the approach track is determined, wherein the target turnout is the turnout on the approach track that is closest to the turnaround train at the current time, and the target turnout connects the approach track and the track to be traveled;

[0060] Obtain the turnout path information corresponding to the target turnout, and determine the stopping position of the turnaround train on the track to be traveled based on the location information, the turnout path information and the travel speed information;

[0061] Obtain the departure route information of the target train on the track to be traveled;

[0062] Determine whether the track area in the departure route information includes the track area where the parking location is located. If it does, split the departure route information to obtain the turnaround parking area information.

[0063] Figure 2 The schematic diagram of the segmented route based on the turnaround train provided by this invention can be referred to. Figure 2 As shown, the return train is labeled as Train 1, and the target train is labeled as Train 2. Figure 2 In this invention, 1G, 3G, 5G, ..., and 9G represent the first, third, fifth, ..., and ninth track segments in the down direction, respectively. Correspondingly, the track segments in the up direction are designated as 2G, 4G, etc. Additionally, 2DG-A and 2DG-B are turnout branches on the up-direction approach track, and 1DG-A and 1DG-B are turnout branches on the down-direction track to be traveled. In this invention, train 1 first communicates with the ATS to inform the system that train 1 needs to turn back. Further, the ATS obtains the current position of train 1 and plans the current turnout path for train 1, i.e., the section from turnout protection signal F2 to signal Z1 is used as the turnout path. In this invention, the target turnout is determined based on the current position information of train 1 on the approach track. Combined with the current speed of train 1, a deceleration operation is set for train 1, thereby generating a corresponding turnout path through the ATS. This allows train 1 to stop in a designated area on the track to be traveled and complete the subsequent reversal. (See reference...) Figure 2 As shown, after track resources are allocated to the train via RC, train 1 can proceed as planned to stop and turn around before signal Z1. Preferably, in one embodiment, a protection zone is built into the stopping area of ​​the turnaround path from F2 to Z1 to improve the safety of train 1 when turning around and stopping.

[0064] Furthermore, the stopping position of train 1 on the track to be traveled is determined. If the stopping position is on the departure route of train 1, the corresponding track resources on the departure route information of train 1 are split, so that train 1 can handle the departure route according to the split departure route information.

[0065] This invention splits the original departure routes into separate resources, enabling trains to depart even when the original departure routes include reverse locking. This significantly shortens the interval between trains after the inserted train turns around, thereby improving operational efficiency.

[0066] Based on the above embodiments, the step of splitting the departure route information further includes:

[0067] Obtain the information of the area to be traveled by the target train on the track to be traveled, wherein the track area corresponding to the information of the area to be traveled is the track between the end of the parking position and the train platform, and the end of the parking position is the end closer to the train platform;

[0068] The step of determining the target travel area information of the target train on the track to be traveled based on the turnaround and parking area information includes:

[0069] The safe interval track area between the target train and the parking position is determined based on the preset minimum safe interval distance between trains;

[0070] Based on the track information corresponding to the safety interval track area and the information of the area to be traveled, the target travel area information is obtained.

[0071] Figure 3 This is a schematic diagram of the orbital resource movement authorization reversal provided by the present invention, which can be referred to. Figure 3 As shown, train 2 is in track section 1G, waiting to depart from the station. The current departure route from signal XC to signal F3 is blocked by a hostile lockout in track section 7G, preventing train 2 from locking and unlocking. Therefore, train 2 must wait for train 1 to clear track section 7G before it can proceed. In this invention, after the RC system receives the ATS command to manage the route from XC to F3, it can refer to... Figure 3 As shown, the RC system automatically splits the XC to F3 route into segmented route 1 (i.e., XC to signal XN1) and segmented route 2 (i.e., XN1 to F3).

[0072] After the departure route information is divided into sections, segmented route 1 from XC to XN1 can be locked. Once signal XC meets the opening condition, train 2 can proceed to the corresponding section based on the locked resources. Furthermore, since segmented route 1 and the turnaround route (i.e., segmented route 2) have locked sections facing each other, there is a risk of conflict. When allocating track resources to train 2, the RC system reclaims the resources of logical section 5G-D based on the preset minimum safe interval distance (e.g., 70 meters), ensuring that train 2's movement authorization can only extend to 5G-D. It should be noted that in this invention, for scenarios with long departure routes, the track section closest to segmented route 2 in segmented line 1 (e.g.,...) is... Figure 3 The track section 5G is divided into multiple sub-sections (such as 5G-A, 5G-B, 5G-C, and 5G-D). The last sub-section is set as a safe interval track area. The extension speed of train 2 can be adjusted in the other sub-sections according to the turnaround status of train 1 (such as whether it has started to change direction), thereby improving train safety while tracking the route.

[0073] This invention improves operational efficiency while ensuring system safety by allocating track resources for segmented routes and retracting track resources of a logical segment length between the train's departure from the platform and the forward turnaround parking area.

[0074] Based on the above embodiments, the method further includes:

[0075] If not, a corresponding departure instruction is generated based on the departure route information, and the departure instruction is sent to the target train.

[0076] In this invention, when the turning-back stopping position of the turnaround train does not overlap with the departure route in the departure route information, the departure route of the target train can be processed directly, further improving train operation efficiency.

[0077] Based on the above embodiments, the step of controlling the turnaround train to travel to the corresponding parking area on the track to be traveled using the turnaround parking area information, and controlling the target train to travel to the target area using the target travel area information, includes:

[0078] Using the information about the turnaround parking area, the track area corresponding to the parking position is kept locked, and the turnaround train is controlled to perform a reversing operation in the track area corresponding to the parking position.

[0079] Using the target travel area information, the track area corresponding to the target travel area information is kept locked, and the target train is controlled to travel to the track area corresponding to the target travel area information.

[0080] In this invention, reference may be made to Figure 3 As shown, after segmented route 1 is opened and locked, the RC system waits to process segmented route 2 from XN1 to F3. When train 1 reaches the 7G switching end of track section, it transmits the switching information to the RC system via IVOC. After the RC checks that the turnaround conditions are met, it locks the XN1 to F3 route, switches the 7G resources of track section 1 of train 1, and thus enables train 1 to change direction and travel.

[0081] Furthermore, the XC to XN1 segmented route 1 is locked. When signal XC meets the opening conditions, train 2 can move forward to the corresponding section based on the locked track resources. This refines the resource locking and resource allocation functions of the RC system, splits the departure route information into two parts, completes the departure route of train 1 in segments, shortens the interval between train 1 and train 2, and improves the utilization rate of track resources.

[0082] Based on the above embodiments, after controlling the turnaround train to travel to the corresponding parking area on the track to be traveled using the turnaround parking area information, and controlling the target train to travel to the target area using the target travel area information, the method further includes:

[0083] Determine whether the turning train has completed the reversing operation and cleared the track area corresponding to the parking position. If so, release the lock of the track area corresponding to the parking position and extend the departure route of the target train on the waiting track forward.

[0084] Figure 4 This is a schematic diagram of the route tracking after the turnaround train has completed the end-changing process, as provided by the present invention. Figure 4 As shown, after the 7G resource reversal in the track section, the RC system will recombine the segmented routes XC to XN1 and XN1 to F3 into route XC to F3. This allows the movement authorization of train 2 to continue tracking and extending forward according to the original departure route information. By tracking train 2, the interval with train 1 will continue to shorten, and the train will eventually travel to the track section corresponding to the departure route information. This reduces the impact of being unable to process routes due to reverse locking and improves operational efficiency.

[0085] The train operation control device based on turnaround trains provided by the present invention will be described below. The train operation control device based on turnaround trains described below can be referred to in correspondence with the train operation control method based on turnaround trains described above.

The departure route splitting module 502 is used to determine the target travel area information of the target train on the track to be traveled based on the turnaround stopping area information, wherein the target area corresponding to the target travel area information is set between the stopping area corresponding to the turnaround stopping area information and the train platform. The route extension module 503 is used to control the turnaround train to travel to the corresponding stopping area on the track to be traveled based on the turnaround stopping area information, and to control the target train to travel to the target area based on the target travel area information.
