Indoor Location System And Algorithm Research Based On I Beacon

With the popularity of mobile Internet terminal facility with satellite global positioning system(GPS),the application Location Services-based(LBS)has become regularly in the common's daily life.Gradually,the demand for indoor positioning applications has been growing with each passing day,such as positioning navigation of indoor parking lot and shopping guide at malls and so on.Therefore,the research on indoor positioning technology and system has become a hotspot topic at present.Researchers have explored the wireless base stations for indoor positioning,like WiFi,ZigBee and others.But there are still few shortcomings in some cases,it is not pragmatic to use these systems.This thesis mainly focuses on the iBeacon sensor introduced by Apple to carry on the indoor positioning algorithm and its application.Based on the study of the current mainstream indoor positioning algorithm,positioning system and practical application requirements,this paper puts forward a general design project of indoor positioning application system,and also it gives the constituent mechanism of the system,as well as its functional design in detail.Then,the paper analyzes and studies both advantages and disadvantages of the positioning algorithm based on traditional three-point positioning and four-point weighting of RSSI.According to the characteristics of iBeacon sensor,a positioning algorithm called multi-triangular weighted MT-RSSI is proposed.The paper also focuses on iBeacon sensor,mainly studies The RSSI signal acquisition and calibration and its way of deployment how to influence positioning accuracy.In this paper,the simulation experiment based on Matlab is designed,and the difference of simulation experiment between the traditional algorithm and MT-RSSI algorithm has been contrasted,it also true of the different deployment modes of iBeacon sensor and its distance.Finally,the paper has analyzed the simulation results and arrived at a conclusion.According to the demands of practical application,this paper designs a general project of indoor positioning application system.A new indoor positioning algorithm,MT-RSSI has been put forward,which is effective for iBeacon sensor.The advantages of multi-triangular positioning algorithm proposed in this paper are proved by simulation experiments.
