With development of iron shoes to prevent slip in stay slip variants of the vehicle are playing more and more important role

and current operation method relies mainly on operating personnel on site

which can’t satisfy the requirement for railway development.CC2431 chip is adopted

based on Zig Bee protocol

iron shoe positioning and anti-running anti-theft monitoring system is constructed.The network consists of network coordinator

localization reference node

iron shoes terminal.Through building Zig Bee wireless sensor networks in railway marshalling yard and station field

the function of positioning

monitoring and communication of the iron shoe is realized.Localization on iron shoes

making the iron shoe monitoring data more meaningful.Iron shoe upper computer monitoring system can real-time display location and status information of iron shoes.Through correction on measured distance in RSSI positioning model by least square method

positioning error is less than 0.5m.Simulation environment performance test results show that the system can meet requirements for management of the iron shoes in railway site.
