Research On Coal Mine Undergroand Localization Or Tracking Algorithm Based On Integration Of WSN And RFID

Main problems of this article is solving the coal mine safety in China, east Ningxia coal mine as the main research object, integration technology of the WSN and RFID and application in the coal mine safety. Research and solve key theory and technology of integration in the ZigBee wireless sensor network and RFID,established dynamic monitoring and trace of coal mine safety. First of all, providing a middleware solution to deal with huge amounts of data in time, in order to solve the problem of RFID data redundancy in reader large-scale deployment, and the acquisition of information transmitted to the corresponding application. Secondly, to improve the traditional trilateration method and improve the positioning accuracy, increase the coverage of RFID signal. Finally, combining with the markov chain model to forecast the target motion trajectory, and the traditional centroid localization algorithm is improved, and adapt it to the prediction model. This paper further provide new theory and method for coal mine safety technology, the RFID and ZigBee wireless sensor network (WSN) integration technology play an important role.
