Aiming at the problem that the traditional positioning device can not carry on the high precision positioning and the motion characteristic analysis problem to the moving target in the micro environment, a small wear device capable of low power consumption can be designed, which can record the human movement trajectory and time, Analysis of the Motion Characteristics of Software. To achieve a ± 0.5m high-precision positioning,the device uses GPS positioning which can reduce the power consumption of GPRS data transmission by optimizing the structure; Finally, through the program we write,the system can analyze the flow and behavior analysis of people within the scope already.From the test we can know that: the device can complete the analysis and processing of information such as high-precision positioning and behavioral path of the moving target (human) in the micro-environment of the specific area;Also the analysis software can deal with the information such as residence time,moving target number and single target position of some specific areas in the micro-environment .
