YU Chun-y · Modern Electronics Technique · 2014
To improve operating efficiency of the available rail vehicles,the radio frequency identification(RFID)technology was adopted to conduct real-time monitoring for the physical position of rail vehicles. The RFID-based real-time positioning system for rail vehicles is proposed. The design scheme,constitution and operational principles of the system are introduced.RFID label placement,RFID read-write and technology communicating with the backend servers are described emphatically.The operating result of this system indicates the RFID-based real-time positioning system for rail vehicles has the advantages of high precision and strong adaptability and can improve the positioning efficiency. A conclusion that the technology has a brilliant prospect for being applied to real-time positioning of rail vehicles on subways and railways inside enterprises has been obtained.
