Design Of Personnel Positioning System In Coal Mine Based On ZigBee

ZigBee technology is to locate coordinates in a manner similar to GPS positioning,Thus the location of the mobile node becomes clear to the related people.First of all,to do the preparation work--finding the general coordinates according to the mobile positioning.After the completion of the related work,the system will check and confirm the information immediately,so as to get a more accurate coordinate information.Then,the system passes the information to the server in some way,obtains the most accurate coordinate position after analysis.In this process,mobile nodes play a major role.The relevant personnel see the production status,progress and personnel activities on the basis of monitoring the location changes of the mobile nodes.It plays a good role in remote monitoring,thereby greatly improving the work efficiency and making the work more convenient.This paper introduces the hardware based on ZigBee technology,focuses on the physical,network,topological structure and hardware architecture of ZigBee network,analyzes the network flow of ZigBee networks,introduces three different positioning algorithms and gives the simulation results of common algorithms.
