The Research On Mining Person Positioning System Based On Zigbee Technology

Now the government and functional departments have been great attaching to the safety of production in coal mine. The mine production safety is always the very concern for every person. So it is very importment to observe the location and information for the mine managers on real time in the ground monitoring center. And it is also very meaningful for the safety production and efficiency of the coal mine companies to achieve the attendance and positioning of coa1miners.This paper mainly introduces the miners positioning system based on Zigbee technology. First,it introduces Zigbee technology,and the CC2430chip is as the core device of the node design in the wireless sensor network. Then it presents the design methods and process of the hardware and software system, and use Matlab tools to simulate and contrast between the old and the improved algorithm, it analysis the feasibility of the system in the laboratory and actual environment of the simulation. Finally, the paper summarized the work and the outlook.
