Abstract

The embodiment of the invention discloses an electronic map slope data generation method. The method includes: obtaining original slope data in a line profile diagram, and generating an original slopedata table according to a preset original slope data structure and the original slope data; inputting the original slope data table to a trackside signal device arrangement diagram, and traversing line, turnout, section and device kilometer post information of the trackside signal device arrangement diagram according to the data in the original slope data table; and generating electronic map slope data according to a preset target slope data structure in a traversal process. According to the method, the original slope data in the line profile diagram is obtained, the original slope data tableis generated, then the trackside signal device arrangement diagram is input, and the electronic map slope data can be automatically generated according to the preset target slope data structure so that the manpower consumption of projects is greatly reduced, the cost is lowered, and the accuracy and the work efficiency of the manufacture of the electronic map data can be effectively improved.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of rail transit, in particular to a method for generating electronic map slope data. Background technique [0002] The Communication Based Train Control System (CBTC) uses the 802.11 standard communication transmission means to complete the train control information interaction and realize the train operation through the real-time and large-capacity two-way data communication between the train and the ground equipment. The safety control of the system has been widely used at home and abroad. In the CBTC system, the onboard ATP subsystem stores electronic maps. In the electronic map, it contains the line, slope, speed limit and trackside equipment information of the whole line. The vehicle-mounted ATP subsystem calculates the emergency braking trigger curve based on the speed-distance curve safety braking model based on the train's position and movement authorization information, c...
