A positioning control method and a high-speed train positioning control system

The present invention discloses a method for positioning control of high-speed trains, the method comprising: using a GPS receiver acquires location information of the train is currently traveling; search with respect to the line corresponding to the geographic location information, if the search for two or more lines, the process proceeds determination step; step of determining the geographic information and the setting information file, and determines whether the train runs in the region of the set, if the judgment result is YES, the information in the prompt line is set to the train driver area; in upon receiving the train driver circuit based on the determination in step prompts selected, the received train line is determined as the current operation of the line. When the present invention by increasing the setting file in the database, so that the case where a plurality of lines of parallel or intersecting lines appear in the section of the train, the train driver can prompt the selection of the line to avoid the positioning control system can not occur identification run line, the line transition problems.
