The Research And Implementation Of The Wireless Mobile Terminal Tracking And Analysis System

With the increasing of the GPS and GIS technology,the wireless location technology has been widely used in various.There are some disadvantage of the time-consuming and the low safety when the public security departments track outside,so developing GIS geographic information system based on wireless location technology will improve the level of outside tracking effectively.And researching the technology that the GPS and GSM integrate and the optimal path algorithm will become an inevitable way.This is also the urgent need of the public security departments to improve the detection efficiency,and there is important theoretical value and practical significance.Firstly,the article deeply researched the related technologies about wireless locate monitoring area,describe separately GPS,GIS and GSM location.GPS location has high accuracy,but there are some shortcoming,for example,it isn’t unable to locate accurately because of the buidings’ block.The GSM location can only identify the rough scope,but it can be an effective supplement in the case where the GPS positioning can not be used.So,this article integrate the two technologies on the basis of widely market research to achieve better positioning effect.Secondly,the thesis gave the hardware design plan about track terminal.The volume must be small on vehicles’ equipment,the power loss is low and the anti-knockong property is good.To be concrete,the hardware realization of main control circuit,GSM wireless communication module TC35i,GPS receiver module GPS-22.Thirdly,we gave the software design of monitoring centre.It includes the database design of control centre,electronic map integration to VB.On the GIS control platforms which integrated electronic map,you can see the information of track terminal location,historical inquiries,traveling path,the location information and so on.This article also focused on the optimal analysis of the goal’s tracking.When knowing the location information of track goal,public security department also need to understand all possible path.The monitoring centre can calculate the optimal path,to the most powerful crack down on criminals.So we use the data structures’ backtracking algorithm,calculate the required path and make the path to display on electronic maps.At last,we tested the platform carefully,analyzed the typical problems,and shared the experiences.
