Problems solved by technology

[0004] 1. Manufacturers of CBTC signal systems uniformly re-create new electronic maps according to the above standards, but this type of method needs to re-create new electronic maps, which requires high costs and is not convenient for practical application;
[0005] 2. Manually convert the vehicle-mounted electronic map data in different formats into the above-mentioned standard map data. This kind of manual conversion method not only has a high error rate, but also takes a long time
However, this type of solution is to first store the electronic map in a common format, and then convert the electronic map in a common format into a map format applicable to different terminals. The conversion process from a common format to a map in a different format is usually complicated, and the actual conversion efficiency is low. In addition, each subway line still uses map data of different formats and standards. After the conversion, the map data of each subway line cannot achieve data interoperability. When the format standard of each subway line changes, it is necessary to re-convert the format. Conversion implementation is costly and inefficient

Embodiment 1

[0058] Such as figure 1 As shown, this embodiment is used for the automatic conversion method of the vehicle electronic map for urban rail interconnection, and the steps include:

[0059] S1. Construction of mapping relationship: obtain the format of the map data to be converted, compare it with the standard map data format, and construct the mapping relationship between the map data format to be converted and the standard map data format;

[0060] S2. configuration file generation: the mapping relationship built by step S1 generates a configuration file;

[0061] S3. Map conversion: Obtain the map data to be converted and the corresponding configuration file, convert the obtained map data according to the configuration file, and obtain the converted standard format vehicle electronic map output.

[0062] In this embodiment, by constructing the mapping relationship between the map data to be converted and the standard map data, a configuration file is generated from the mappi...

Embodiment 2

[0105] Such as Figure 9 As shown, consistent with the principle of embodiment 1, this embodiment is to realize the conversion of the vehicle-mounted electronic map of urban rail interconnection, by forming a map by a view module, a data reading module, a public module, a data conversion module, and a data writing module Conversion system, in which the view module is used to provide a visual data interaction interface, the read-in data module is used to read in the map data and configuration files to be converted, and the public module is used to provide conversion between data and the corresponding ID number in the local data Converted to an ID number corresponding to the interconnection numbering principle, the data conversion module is used to convert the map to be converted into standard map data, and the write data module is used to write the converted standard map data into the interconnection file, through the above The map conversion system converts the original electr...

Abstract

The invention discloses a vehicle-mounted electronic map automatic conversion method and system for urban rail interconnection and interworking, and the method comprises the steps: S1, obtaining the format of to-be-converted map data, comparing the format with a standard map data format, and constructing a mapping relation between the to-be-converted map data format and the standard map data format; S2, generating a configuration file according to the mapping relationship constructed in the step S1; and S3, acquiring map data to be converted and a corresponding configuration file, and converting the acquired map data according to the configuration file to obtain a converted vehicle-mounted electronic map output in a standard format. Interconnection and intercommunication of urban rail vehicle-mounted electronic map data can be achieved, and the method has the advantages of being simple, low in conversion cost, high in precision and efficiency and the like.

Description

technical field [0001] The invention relates to the technical field of urban rail transit, in particular to a method and system for automatic conversion of vehicle-mounted electronic maps for urban rail interconnection and intercommunication. Background technique [0002] At present, various manufacturers of urban rail transit in China usually use their own independent CBTC (train automatic control system) signal system, which is not convenient for the mutual compatibility and "communication" between different systems of urban rail transit and cannot realize data interconnection and intercommunication. In order to realize the interconnection of data between cities, between different manufacturers, and between the vehicle signal system and the ground signal system, the interconnection technical standards that meet the needs of domestic urban rail transit have been formulated, and the urban rail data interconnection The most critical thing is that the on-board signal equipment...
