Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
The embodiment of the invention provides a method for generating a code sequence table of a railway line, which specifically comprises the following steps as shown in figure 1:
101. and acquiring an engineering data table set of the target railway line.
The project data sheet set in the step is composed of a group of project data sheets, and project implementation standards and requirements are provided for a construction executive party by a design party according to projects corresponding to a target railway line. The engineering data table contains data tables such as a station information table, a line speed table, a line slope table, a signal point track section data table, a transponder position table, a turnout information table, a station train route information table, a line data table and the like.
By acquiring the data in the engineering data tables, parameter information of each station, line section and related supporting equipment in the target railway line can be obtained.
102. And extracting stations in the target railway line and the sections governed by the stations according to the engineering data table set.
The target railway line generally comprises a plurality of stations, and the railway line needs to be divided into a plurality of sections for routine maintenance and repair at a later date, and the sections of the line are allocated to the specified stations for management, and the specific allocation needs to be extracted from an engineering data table. Therefore, each station is configured with a corresponding jurisdiction zone, and in this step, the pipeline zone line corresponding to each station is obtained according to the data in the engineering data table.
103. And determining section sequencing corresponding to the line to which the target station belongs according to the data in the engineering data table set.
Due to the continuity of the lines, the pipeline section to which the station belongs can be divided into a plurality of lines, such as a main line (a line on which a train runs) and a lateral line (a line on which the train stops in the station), the main line is divided into an uplink line and a downlink line, and the uplink line and the downlink line can be divided into a forward direction and a reverse direction; the siding can be divided into siding receiving and siding departure routes and the like.
The method comprises the steps of determining a specific line to which a target station belongs according to contents in an engineering data table, wherein the specific line comprises a main line and a lateral line, determining all line sections forming the line according to each line, and combining and sequencing the sections in the line according to the adjacent relation between the sections and the design advancing direction of a train.
104. And sorting the sections into corresponding section codes according to the coding rules corresponding to the lines and generating a code sequence table of the line to which the target station belongs.
Because the target station includes multiple routes and the route sections in each route are sorted differently, each route in the target station needs to generate a corresponding code sequence table. For different lines in the target station, each section can be coded according to the coding rule corresponding to the line. The coding rule of the line is a track circuit coding principle determined according to the technical specification of the column control center for the states of track signals in the positive line, the side line and the line.
The code sequence table generated in this step may be output in different formats according to the requirements of the subsequent application, including but not limited to EXCEL, WORD, TXT, PDF, CAD, etc.

Compared with the manual coding sequence table in the prior art, the method and the device can realize automatic generation of the coding sequence table under the condition that the obtained engineering data table is complete in content, can avoid the conditions of coding omission and wrong coding caused by manual coding, improve the generation efficiency and accuracy of the station line coding sequence table, and ensure the railway transportation efficiency and the driving safety.
Further, a preferred embodiment of the present invention is described in detail with respect to the category division of the route belonging to the target station and the generation process of the route corresponding code sequence table on the basis of fig. 1, and its specific steps are shown in fig. 2, and include:

The station train route information table is used for recording all route information with a code sending function in each station in a target railway line, and comprises the following steps: type of route, transponder number, name/length/carrier frequency information of track segment, etc.
The route data table is used for recording the positive section names, the signal point types, the carrier frequency information and the like of all stations in the target railway route.
202. And checking data in the engineering data table.
Due to the duplication of the data in the engineering data table obtained above, and the sources of different engineering data tables may be different. Therefore, by using repeated data in different tables, the accuracy verification can be carried out on the data of the target railway line, and the problem of inconsistent information is avoided.
Specifically, the station information table, the transponder position table, the station train route information table, and the route data table are taken as examples:

If no repeated number exists, whether the carrier frequency information of the administration section of the target station in the line data table is the same as the carrier frequency information of the same section in the train route information table of the station of the target station is detected, if not, error reporting information containing the section corresponding to the target station is generated, and the specific positions of the target station and the section in each table are indicated.
203. And extracting stations in the target railway line and the sections governed by the stations according to the engineering data table set.
According to the acquired district dominated by the station, all train running routes can be determined according to the adjacent relation between districts, and the routes can be divided into a main route and an inside-station route. The code sequence table generated aiming at the positive line comprises a downlink forward code sequence table, a downlink reverse code sequence table, an uplink forward code sequence table and an uplink reverse code sequence table; and the code sequence table generated for the station inner side line comprises a station inner side line vehicle receiving code sequence table and a station inner side line vehicle sending code sequence table.

205. And sorting the sections into corresponding section codes according to the coding rules corresponding to the lines and generating a code sequence table of the line to which the target station belongs.
In the above steps 204 to 205, the generation manner of the code sequence table is described according to different routes:
firstly, for a main line, when determining the section sequence corresponding to the main line to which a target station belongs, searching a section contained in the main line of the target station and an adjacent section of a station adjacent to the target station; and determining the forward section sorting of the descending line, the reverse section sorting of the descending line, the forward section sorting of the ascending line and the reverse section sorting of the ascending line corresponding to the ascending line according to the adjacent relation of the sections.

TABLE 2
It should be noted that, before coding each segment according to the reverse operation tracking code-sending principle and the downlink reverse segment sorting and the uplink reverse segment sorting, in order to avoid the problem that a plurality of segments are occupied in the reverse operation process, whether a segment needing to be combined and coded exists is detected according to the name of each segment and the corresponding signal point type in the line data table recorded in the engineering data table, if yes, the combination rule in the engineering data table is obtained, segment combination is performed according to the corresponding rule, and the combined segment is coded according to the reverse operation tracking code-sending principle. Wherein the signal point types of the sections include: outbound port, outbound signal, pass signal, no signal, etc. The signal point types corresponding to the same segment are fixed, and when the signal point types corresponding to the segment are different between the forward line and the backward line, generally, the signal point type is a passing signal in the forward line, and the signal point type is a non-signal condition in the backward line, at this time, it is necessary to search the segment adjacent to the segment according to the name of the track segment in the backward line in the line data table, and the signal point type of the segment is not a non-signal condition, and then merge and encode the two.

And generating corresponding receiving access code sequence table and departure access code sequence table for each section code by using the code generation principle.
Since the receiving entry code sequence table of the station inner side line is generated in a similar manner to the departure entry code sequence table, it is not described one by one here. The following table 3 exemplarily shows a code sequence table of S3-XN siding departure routes in a certain station:
TABLE 3
