With RFID Tags Technology To Achieve Flat Shunting Carriage Monitoring System

Flat shunting business is one of the most important aspects in the freight rail,Marshalling operational efficiency direct impact on the operation of the whole railway line.In a train marshalling yard,to ensure the good functioning,it should basic on the carriage location information.The traditional manner gathering of information is not only low efficiency,and there are hidden dangers of the accuracy.To avoid these problems,the design of this systems utilizing RFID technology developed an ultra-low power wake-up semi-active electronic tag system.It’s used to collection the carriage position information of the marshalling,and transmission to the integrated information server stations.To help the managers staff supervision of the carriage positions.For a longer use life-cycle characteristics of the installation of vehicle electronic tag and the read mode of the tag,Designed an active electronic tag and the reader system based on low-frequency signals can be remotely wake.Taking into account the characteristics of their reading design a data transfer anti-collision algorithm.This system is able to obtain reliable carriage information.Available installed in a number of readers complete marshalling carriage positioning.Finally,through the system test,this design meets the demand of 50 meters of wake distance,And in the tag to achieve the storage of 2048 bits of information,and it over eight years of service life.
