Study On Personnel Position System Of Underground Mine Based On RFID

China’s coal production and consumption are ranked among the top of the world, followedby a coal mine safety problem is becoming more and more serious, the status of frequentaccidents and disasters happened in the coal industry. When an accident occurred, theunderground information can not be fully understood by the ground staff, so that aid workers cannot be accurate, timely grasp the personnel’s precise location, resulting in a large amount ofproperty loss and casualties. Therefore, to establish a positioning system of rapid reactionunderground personnel location information is of great social significance and economic value.With the continuous development of radio frequency identification technology, providesstrong technical support to build underground personnel positioning system. In this paper, theexisting RFID technology, positioning technology and relatively mature positioning systembased on RFID technology to do a thorough analysis and study, the related technology, workflowand positioning principle of positioning system was introduced in detail. On this basis, wepropose a set of detailed design RFID-based underground personnel positioning system. Thispaper analyzes the shortcomings of traditional LANDMARC algorithm, in order to solve theproblem and puts forward the improved algorithm, the improved adaptive localization algorithmcan choose its own reference. Then the framework and the layout of the positioning system arestudied,combined with underground structure, gives the reader, reference tag location optimalplacement.On the basis of the research on the key technology in the layout of underground positioningsystem, with the MyEclipse development platforms and MySQL database technology, the systemadopts B/S model of three layer structure model and modular design method, using theobject-oriented language Java and the development of the MVC framework, achieve the labelinformation generation and management, personal positioning information query, the readerinformation generation and management, positioning system was introduced in detail in the various functional modules, each module is given of the process design and operation interface.The user can through the front desk remote access and query data, the administrator can convertand manage data by background.
