Movement Characteristic Analysis System Based On Crowd In Specific Environment

In view of the fact that the traditional positioning device can only obtain the position information of a person but can not provide the detailed motion characteristic analysis,a system is designed,which is based on a specific environment for analyzing the movement characteristics of a crowd.The system not only can improve the positioning accuracy to ± 0.5 meters,but also can study the movement characteristics of the crowd,including:the number of moving targets in a specific environment,a single moving target residence time in the environment,the average moving speed and so on.In addition,the front-end positioning device and motion profile service terminals provide an open source data interface that provides analysis that requires first-hand location data to provide the conditions for research.For the system of crowd motion feature analysis system in a specific environment,this paper studies in the following order:Firstly,it is hardware design and analysis of the system location information acquisition equipment,including the main control circuit design,GPS module to provide positioning services,Data service GPRS module circuit analysis and research;then it is the front-end positioning device software design;Finally,it is the system movement characteristic analysis terminal design,,which introduced the use of the system and verified that the System accuracy and effectiveness through the collection of experimental data on the Emerald Lake scenic spot.In the system of front-end location information acquisition device research,firstly,this paper selects the appropriate host processor,and then the paper analyses and designs the hardware and equipment to be used in the module circuit.Among them,the two issues are laid special stress on analyzing,1.How to design the power supply and select the power to meet the power requirements of each module,2.It is the design for the circuit layout of the special requirements With the GPRS module network attached to.When these two meet the requirements,you can make the front-end equipment for stable work.Because the three serial ports need to communicate with each other during the debugging and using of the front-end equipment,communication configuration and design are the key problems to be solved by the software,and each communication must be ensured to be unblocked.In addition,the detection of network attachments has become important as a guarantee of normal data transfer between the front-end equipment and the server.Finally,through the field application test in Emei Lake Scenic Area in Hefei,this paper verifies and indicates the function and operational integrity of the system designed so as to realize the movement characteristic analysis.At the end of the paper,this paper will give a basic summary of the work done and give a prospect for future work.
