Embodiment 1

[0054]A method for processing railway high-precision map data includes the following steps:

[0055]S1. Collect the geographic coordinate data of the railway site;

[0056]S2. Process the geographic coordinate data collected by S1 to obtain complete high-precision geographic coordinate data;

[0057]S3. Perform mileage formatting, feature points and feature area identification on the complete high-precision geographic coordinate data obtained in S2 to obtain railway high-precision map data;

[0058]S4. Verify the railway high-precision map data obtained by S3;

[0059]S5. Continuously maintain railway high-precision map data.

Embodiment 2

[0061]The difference between this embodiment and Embodiment 1 is that the geographic coordinate data includes: the latitude, longitude, height of the location point, and current data accuracy;

[0062]The method for collecting geographic coordinate data of the railway site in step S1 includes the following steps:

[0063]S101. Install data collection equipment on the train, and use the process of train operation on the line and in the station to collect on-site data

[0064]S102. Install the data collection equipment on the patrol inspection equipment, and use the process of the equipment running on the line and in the station to collect on-site data

[0065]S103. The staff carry data collection equipment to manually collect geographic coordinate data in the line and the station.

[0066]Further, the method for processing the collected geographic coordinate data in step S2 includes:

[0067]S201. Analyze the collected data: determine which are geographic data related to field equipment and which are ...

Embodiment 3

[0090]A railway high-precision map data system also includes a collection terminal for collecting geographic coordinate data of a railway site and a processor for executing steps S1-S5.

Abstract

The invention discloses a method and system for collecting, clearing, formatting, marking, verifying, generating, and maintaining railway high-precision map data. The terminal can collect on-site geographic coordinate data, and the system can target the collected on-site geographic coordinate data. , to clean up, format and mark, and finally form a high-precision railway map, and conduct verification and continuous maintenance. It solves the problem that the existing railway digital map cannot support the judgment of refined business requirements, and cannot be quickly updated to display the latest status of the line and station equipment.

Description

Technical field[0001]The invention relates to the field of electronic maps, in particular to a method and system for processing railway high-precision map data.Background technique[0002]At present, the use of a combination of ordinary maps and on-site positioning equipment can realize the real-time display and monitoring of equipment coordinates on the map; however, it is necessary to have a high-precision map that serves the railway industry in order to achieve a series of refinement in the railway industry. Business requirements, such as:[0003]On which line is the personnel, equipment or train located at the site (upstream or downstream), and which lane of the station (neijiang station strand 3 or Neijiang station strand 4); where are the site personnel, equipment or trains It is located near which mileage point; where personnel, equipment or trains are located near which characteristic point of which turnout in the station yard (basic rail joint, switch before switch, straight af...
