Description

Technical Field

[0001] This invention relates to the field of rail transit, and in particular to a method, system, device and storage medium for generating a rail transit train identification zone. Background Technology

[0002] Train identification zones in urban rail transit are mainly used to identify whether a train exists in the current area. If a train exists, a certain safe distance must be maintained between the front and rear, and no route can be arranged.

[0003] Since it is used to identify trains, the train identification zone is usually a single path that may pass through different sides of the turnout, so the direction of the turnout needs to be taken into account.

[0004] Currently, generating train identification zones usually requires actual project personnel to configure the area. During manual configuration, various problems may occur, resulting in the area not having a single path, leading to unreasonable configuration and low efficiency. Summary of the Invention

If it does not exist, it is considered to be the boundary of the upward direction.

[0019] Step S24: Determine whether the track segment in the down direction is located and whether the track segment connected in opposite positions exists in the track segment list of the current identification area. If it does not exist, it is considered to be the boundary of the down direction.

[0020] Step S25: For each train identification zone, determine whether there are multiple upward or downward direction boundaries. If so, the identification zone is considered to be configured unreasonably, an alarm is triggered, and subsequent generation steps are not performed for that identification zone.

[0021] Preferably, step S3 includes the following sub-steps:

[0022] Step S31: Use the lower direction boundary as the starting track segment;

[0025] Step S34: Use this track segment as the new starting track segment and execute step S31 until a track segment at the upper boundary is found.

[0026] Step S35: Return all recorded turnout information.

[0028] Preferably, step S4 includes identifying the turnout information, including the train identification zone name, the turnout name, and the connecting side of the turnout in the current identification zone route.

[0029] Preferably, the method further includes: outputting the result to a template, wherein the template is a file in par format.

[0030] According to a second aspect of the present invention, a rail transit train identification zone generation system is provided, the system comprising:

[0031] The input module is used to input line data and configuration data;

[0041] Preferably, the turnout information calculation module includes:

[0042] Define a submodule for the track segment that uses the lower direction boundary as the starting point;

[0043] The fourth judgment submodule is used to determine whether there is a turnout in the upward direction of the starting track section. If there is, the turnout name and the connecting side information of the turnout are recorded.

[0044] The first search submodule is used to search for track segments that are located in the upward direction and are connected in opposite positions in the current identification area track segment list;

[0045] The second search submodule is used to take the track segment as the new starting track segment and execute the definition submodule until the track segment at the upward boundary is found.

[0051] 2) This invention uses the boundary of the down direction as the starting track segment, determines whether there is a turnout in the up direction of the starting track segment, searches for track segments in the current identification area track segment list that are located in the up direction and connected in opposite directions, and uses this track segment as the new starting track segment. This process is repeated until a track segment with the boundary of the up direction is found, which improves the accuracy of turnout information identification and thus improves the accuracy of the train identification area.

[0052] 3) This invention can automatically and accurately identify whether the configuration of the identification area is reasonable, and feed it back to the configuration personnel through a par format template file so that the configuration personnel can grasp the current train identification area configuration status in a timely and accurate manner.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0058] Example

[0059] like Figure 1 As shown, this embodiment provides a method for generating a rail transit train identification area, the method including:

[0060] Step S1: Input line data and configuration data;

[0061] The track section connection status is as follows: Figure 4 As shown, the line data includes track section information and turnout information; the configuration data includes the train identification zone, specifically the track section name and the train identification zone name, as shown in Table 1 below.

[0062] Table 1 Identification Area Information Table

[0063]

[0064]

[0065] Step S2: Traverse the train identification area in the configuration data, and determine whether the train identification area configuration is reasonable based on the number of boundaries. If the configuration is reasonable, proceed to step S3; otherwise, issue an alarm and end the subsequent steps. Specifically, this includes the following sub-steps:

[0066] Step S21: Traverse the train identification areas in the configuration data to obtain a list of track sections for each identification area;

[0067] Step S22: Traverse each track segment to obtain the corresponding track segment information in the line data;

[0068] Step S23: Determine whether the track segment in the upward direction is located and whether the track segment connected in opposite positions exists in the track segment list of the current identification area. If it does not exist, it is considered to be the boundary of the upward direction.

[0069] Step S24: Determine whether the track segment in the down direction is located and whether the track segment connected in opposite positions exists in the track segment list of the current identification area. If it does not exist, it is considered to be the boundary of the down direction.

[0070] Step S25: For each train identification zone, determine whether there are multiple upward or downward direction boundaries. If so, the identification zone is considered to be configured unreasonably, an alarm is triggered, and subsequent generation steps are not performed for that identification zone.

[0071] according to Figure 4 The line connection status is obtained through Figure 2 According to the process method, in D1, B1 is the downlink boundary and B5 is the uplink boundary; in D2, B1 and B4 are downlink boundaries, and the number is greater than 1; in D3, B1 and B3 are both uplink and downlink boundaries, and the number of uplink and downlink boundaries is greater than 1; therefore, only D1 is a reasonable identification area.

[0072] Step S3: Calculate the turnout information in the train identification zone, which includes the following sub-steps:

[0073] Step S31: Use the lower direction boundary as the starting track segment;

[0074] Step S32: Determine whether there is a turnout in the upward direction of the starting track section. If there is, record the turnout name and the connecting side information of the turnout.

[0075] Step S33: Search for track segments located in the upward direction and connected in opposite positions that exist in the current identification area track segment list;

[0076] Step S34: Use this track segment as the new starting track segment and execute step S31 until a track segment at the upper boundary is found.

[0077] Step S35: Return all recorded turnout information.

[0078] according to Figure 3 The method described first obtains the down-direction boundary track segment B1 as the starting point; then it determines that there is a turnout P1 in the up-direction, records its name and the location of its connecting side; it searches in the up-direction direction and obtains B2, whose location side is in the track segment list of the identification area, and continues to loop with B2 as the starting point; the loop continues until the current track segment is the up-direction boundary B5, at which point it exits the loop. The information after the turnout information calculation is completed is shown in Table 2 below.

[0081] Step S4: Generate the identification zone and the turnout information of the identification zone, and output the results.

[0082] The identification zone information includes the train identification zone name, the name of the boundary track segment in the up direction, and the name of the boundary track segment in the down direction. In this embodiment, the final identification zone information is shown in Table 3 below.
