Abstract：With the development of railway transportation in the direction of high-speed,heavy-duty and intelligent,the demand for train operation safety monitoring is becoming increasingly prominent.As a key equipment to ensure the integrity of the train,the positioning accuracy and reliability of the train tail device are crucial.This paper introduces the high-precision positioning technology based on the Beidou satellite navigation system(BDS),discusses its application in the column tail device,and analyzes its technical advantages,implementation methods and practical application effects.This paper proposes an application scheme using Beidou high-precision positioning technology for intelligent upgrade to solve the problems of weak signal of existing train global positioning system(GPS)in complex areas such as mountains and tunnels in China and the slow progress of intelligent progress of existing train tail devices.The research results provide a reference for the networked and intelligent development of railway transportation of heavy-duty trains.
