Description

Technical Field

[0001] The present invention relates to a rail transit signal system, and in particular to a method, device and medium for calculating information of a track section takeover area controller based on reverse path search. Background Art

[0002] When a train enters the overlapping area of ​​the regional controller boundary, it means that the train is about to leave the current regional controller range and enter the adjacent regional controller range, which tells the train operation control software to prepare for switching regional controllers. Each track section provided by the offline data preparation tool contains the takeover regional controller information, which can know the regional controller it may switch to after obtaining the positioning information and running direction of the track section where the train is located.

[0003] In the previous method of calculating the information of the regional controller when the track segment takes over, the regional controller is added to all the track segments on the other side of the boundary overlapping area. Although this is simple to implement, it does not take into account the problem that the associated direction will be changed due to the direction change points in the overlapping area, and the track segments that are not statically connected to the boundary do not need to be associated with the regional controller. Adding the association may cause the train operation control software to add unnecessary calculations, affecting operation efficiency.

[0004] Whether a track segment is statically connected to a boundary depends on whether there is a one-way path between the track segment and the boundary of the regional controller. Searching from the track segment will find many invalid paths due to switches, but there may be only one path that can actually connect to the boundary. The calculation in the middle will cause the offline data preparation tool to run inefficiently.

[0005] After searching, Chinese patent publication number CN111874044A discloses a method for transferring vehicles across overlapping areas. Specifically, after the target vehicle completely leaves the first axle counter and enters the second axle counter, if the transfer area controller receives the second axle counter occupancy status signal sent by the takeover area controller, the first axle counter is set to an idle state, and the first axle counter idle state signal is sent to the takeover area controller, so that the takeover area controller updates the state of the second axle counter according to the idle state of the first axle counter, and controls the target vehicle to pass through the overlapping area according to the states of the first axle counter and the second axle counter. This patent solves the problem of inconsistent delays in the axle counter section occupancy status sent by the first computer interlocking received by the transfer area controller and the axle counter section occupancy status sent by the takeover area controller, resulting in discontinuity in the axle counter section occupancy status inside the transfer area controller and the takeover area controller, and provides a guarantee for the train to smoothly complete the switching between different overlapping areas. However, this patent does not involve how to correctly calculate the direction of the takeover area controller when there is a direction conversion point in the overlapping area. Summary of the invention

[0006] The purpose of the present invention is to overcome the defects of the above-mentioned prior art and to provide a method, device and medium for calculating the information of a track segment takeover area controller, which can accurately associate the track segment statically connected to the boundary of the area controller to the takeover area controller, and can correctly calculate the direction when there is a direction change point.

[0021] Step S305, taking the other side area controller in step S302 as a reference, execute steps S302 to S304 again.

[0022] As a preferred technical solution, the initial search direction in step S303 is specifically:

[0023] Find the track segment of the current area controller that is closest to the overlap area boundary in the direction of the starting track segment, and use the opposite direction of this direction as the starting search direction.

[0045] like Figure 1 As shown, the present invention provides a method for calculating the information of the track section takeover area controller, the method comprising the following steps:

[0049] Step S4, converting the result of step S3 into the takeover area controller information of each reachable track section. Step S5, outputting the converted result of step S4.

[0050] The line data in step S1 includes track section information, area controller information and area controller boundary overlap area information.

[0051] The area controller boundary overlap area information in step S2 includes area controller information on both sides, track segment information contained in the overlap area by the area controllers on both sides, and track segment information of the area controllers on both sides that is closest to the overlap area boundary.

[0052] like Figure 2 As shown, step S3 specifically includes the following steps:

[0053] Step S301, traverse all the overlapping areas of the regional controller boundaries to obtain the current overlapping area that needs to be calculated;

[0054] Step S302, taking the area controller on one side of the current overlapping area as a reference, taking the track segment of the area controller on the other side of the current overlapping area closest to the boundary of the overlapping area as a search starting point;

[0055] Step S303, finding the direction of the track segment of the current area controller closest to the overlap area boundary in the starting track segment, and taking the opposite direction of the direction as the starting search direction, and recording the starting search direction as the direction of the starting track segment;

[0056] Step S304, along the search direction, all paths are searched according to the connection relationship shown by the track segment information in the line data, each of the paths only includes the track segments in the current overlapping area, and the search direction is changed when a direction change point is encountered to continue the search, and each track segment in the path and the search direction at that time are recorded during the search process;

[0057] Step S305, taking the other side area controller in step S302 as a reference, execute steps S302 to S304 again.

[0058] like Figure 3 As shown, step S4 specifically includes the following steps:

[0059] Step S401, initializing the track segment and its uplink and downlink direction takeover area controller table;

[0060] Step S402, traverse all calculated overlapping areas to obtain all regional controllers and all track segments they searched and corresponding search direction information;

[0061] Step S403, for each track segment, add the current zone controller to the takeover zone controller table in the opposite direction of the current track segment search direction.

[0062] In the step S5, the result converted in the step S4 is output to a template, and the template is a file in csv format. Specific embodiments

[0064] The track section line connection of this embodiment is shown in Figure 4 shown.

[0065] Step A: Input line data;

[0066] The input line data, except for the zone controller boundary overlap information, can be found in Figure 4 shown.

[0067] Step B: Obtain all the area controller boundary overlap areas that need to be calculated;

[0068] The regional controller boundary overlap area information is shown in Table 1 below;

[0069] Table 1

[0070]

[0071]

[0072] Step C: Calculate all track segments and directions that can be reached by static connection within the current overlap region at the region controller boundary in each overlap region;

[0073] according to Figure 3 The method shown first obtains the upstream ZC1 of BOA1, and uses the downstream B3 as the starting track segment. Since B2 is in the downstream direction of B3, the upstream direction is used as the search direction, and B3-upstream information can be obtained. Then, the overlapping area boundary is encountered and the search is terminated.

[0074] Then obtain the downstream ZC2 of BOA1, and take the upstream B2 as the starting track segment. Since B3 is in the upward direction of B2, the downward direction is used as the search direction, and the B2-downward information can be obtained; then B2 searches in the downward direction, and at this time encounters a direction change point, and changes the search direction to the upward direction, and obtains the B1-upward information; then encounters the boundary of the overlapping area and ends the search.

[0075] The calculation of BOA2 and BOA3 is the same as that of BOA1.

[0076] The information after calculation is shown in Table 2.

[0077] Table 2

[0078] Overlap Area Name Region Controller Name Track section name direction BOA1 ZC1 B3 Up BOA1 ZC2 B2 Downside BOA1 ZC2 B1 Up BOA2 ZC2 B6 Up BOA2 ZC3 B4 Downside BOA2 ZC3 B5 Downside BOA3 ZC2 B8 Up BOA3 ZC4 B4 Downside BOA3 ZC4 B7 Downside

[0079] For BOA2, although B7 is included, it is not included in the calculation because it cannot be statically connected to B5; for BOA3, although B5 is included, it is not included in the calculation because it cannot be statically connected to B7.

[0080] Step D: Convert the result of step C into the takeover area controller information of each reachable track segment:

[0081] Traverse the information in Table 2, reverse the direction, and put it into the takeover area controller table of the corresponding direction of the corresponding track segment. Take B4 as an example, it exists in the track segments related to ZC3 and ZC4 at the same time, and the direction is the downlink direction. Therefore, after the direction is reversed, B4's uplink direction takeover area controller table contains ZC3 and ZC4.

[0082] The final information is shown in Table 3.

[0083] Table 3

[0084] Track section name Upstream direction takeover area controller table Downstream direction takeover area controller table B1 ZC2 B2 ZC2 B3 ZC1 B4 ZC3; ZC4 B5 ZC3 B6 ZC2 B7 ZC4 B8 ZC2
