Train satellite positioning and message transmison system

Abstract

The invention discloses a train satellite positioning and information transmitting system which is suitable for the train positioning and information transmission. The system comprises a positioning subsystem, a map-matching subsystem, a data record subsystem, a communication subsystem and a main processor; wherein the positioning subsystem is used for outputting the positioning coordinates of latitude and longitude. The map-matching subsystem matches the positioning output to a data map. The data record subsystem is used for recording the data in file format in a Secure Digital memory card. The communication subsystem is used for automatically detecting the possibility of three communication signal paths and the switchover of three communication methods. The main processor is used for completing data processing and data switching. The train satellite positioning and information transmitting system is used for positioning and monitoring the train. With satellite communication, satellite integrated positioning and full-line coverage communication system, the invention meets the needs of the communication, command, dispatch, distress handling, supervision and monitoring of low density rail track.

Description

technical field [0001] The invention relates to a train satellite positioning and information transmission system, which belongs to the technical field of vehicle positioning and information transmission in the field of rail transit. Background technique [0002] Satellite positioning is a successful example of modern high-tech achieving both military and civilian uses. Satellite positioning has become a worldwide high-tech industry. In the field of satellite positioning applications, vehicle applications account for the largest proportion, accounting for about 50% of the total, mainly divided into two categories: vehicle tracking systems and vehicle navigation systems. In the past ten years, my country's satellite positioning application has also developed rapidly. Satellite positioning technology has penetrated into many typical application systems of the national economy, bid farewell to the enlightenment stage, and integrated into the process of my country's modern info...
