Design of High Precision Positioning System for Urban Rail Transit Train Based on Wireless Induction Technology

Based on the analysis of traditional positioning methods of urban rail transit train, a design scheme of high precision positioning system based on wireless induction coded cable is proposed, and high precision positioning and speed measurement of urban rail transit train can be realized. The principle to realize the positioning system is expounded. The structural composition of the system is introduced. The function and working content of each sub\|system are analyzed. A set of high precision train positioning system is designed by taking the test line as an example. The application results show that the high precision positioning system is applicable and reliable.
