Embodiment

[0042] The content of this embodiment is based on two parts. Firstly, other data tables in the electronic map are generated through the method of positive sequence calculation by using the existing manual statistical data tables. The positive sequence calculation method is described as follows: The generation of line data is based on track equipment. According to different types of line equipment, generate corresponding data for each type of equipment, and then link them together according to the business logic association relationship between these indicators, and establish corresponding data tables.

[0043] The specific method of generating the table is illustrated with an example. For example, in the known route map, the basic data is manually counted, and the link, axle counting section, logic section, signal machine, turnout and other equipment are used as the basis for judging the basic data table, and the calculation After the known route name field in the route table,...

Abstract

The invention relates to a method and system for generating electronic map data based on forward sequence calculation and reverse sequence check. Including: a data preparation step for obtaining the basic data of the manual statistics of the line map; a data processing step of obtaining the starting and terminal line equipment from the basic data of the manual statistics of the line map, and obtaining The business data required for making electronic maps. Therefore, the present invention has the following advantages: by obtaining the start and end points of the routes where two signal device devices are located in a target area, the topological relationship between the devices is determined according to the index numbers of the signal devices; according to the attributes corresponding to each scene, automatic Generate the corresponding route data, no longer rely on the route map provided by the track design unit, and do not need the basic data of the secondary processing route. The process of generating route electronic map data is simple, the labor input cost is relatively low, and the data accuracy rate is high. It is also more flexible when modifying.

Description

technical field [0001] The invention relates to an electronic map generation method and system, belonging to the technical field of rail transit, in particular to a method and system for generating electronic map data based on forward sequence calculation and reverse sequence check. Background technique [0002] In the field of rail transit, data generation usually includes two methods; one is to rely on the track design unit to provide the line map, and manually count the basic data according to the line map, using link, axle counting section, logical section, etc. as the basic data table to generate corresponding electronic map data. This method is relatively simple and easy to upgrade and transform, and is chosen by most users; specifically, the generation of line data is based on track equipment. According to different types of line equipment, corresponding data is generated for each type of equipment, and then according to the correlation between these indicators, they ...
