A real-time automatic generation method of train line spatial data

Abstract

The invention discloses a train route spatial data real-time automatic generation method. The method includes the following four steps: construction of a train network database, construction of a train information database, automatic generation of train routes, and uniqueness determination of the train routes. While a train timetable is issued, the train timetable is decoded automatically in real time, train route spatial data is generated automatically, the automatically generated routes are selected and checked on the basis of train GPS position information, and finally unique and accurate train route spatial data is generated. The method services applications relying on the train route data, ensures accuracy and reliability of basic information of the applications, greatly reduces the cost of manual route drawing, and increases the data updating speed.

Description

technical field [0001] The invention belongs to the technical fields of geographic information system, railway planning, railway construction and railway operation dispatching, and relates to a real-time automatic generation method of train line spatial data, in particular to a real-time automatic generation of train running line method according to a train timetable. Background technique [0002] The train running route is the basis for real-time display of train running status, train arrival time forecast, train delay assessment and train scheduling. With the continuous development of my country's railway construction, especially during the busy period of travel such as the Spring Festival travel, the adjustment of the train timetable is relatively large. Every timetable adjustment is accompanied by a redrawing of the train lines. At present, after the adjustment of the train operation map, it is difficult for other departments and institutions in my country except the ra...

Problems solved by technology

[0004] Aiming at the problems that the current railway line drawing has a large manual dependence and the spatial data of the civil railway lines in my country lags behind and is not updated in time, the present invention provides a real-time automatic generation method of the train line database based on the train timetable. The method is based on the public train timetable Table information, with the support of geographic information system technology, realizes real-time, rapid and automatic generation of railway lines, which can ensure the timeliness, economy and reliability of railway line spatial data updates
