The Research And Application About Location Algorithm Based On Short Distance Communication Technology

The indoor location techonogy is become an important research direction oflocation techonogy right now, and it is a widly used in location field. Today indoorlocation technology can be divided into two technical directions:the wide area andthe local. It is a new wireless communication technology, which has arousedgeneral concern around the world. In this field, the Mobile location technologiesof Short Distance Communication, especially the hybrid technology, hasdeveloped speedy in recent years. In order to accelerate the breakthrough, weshould make best use of the advantages and by pass the disadvantages. But how toapply it in business is just at starting stage, especially those civil area withenormous commercial potential.This thesis based on the location algorithm of Short Distance Communicationtechnology, combined with BP-GA algorithm. Moreover after obtaining the initialcoordinates, use the Taylor series localization algorithm to optimize the final testedpoint. This is the major algorithm of the indoor positioning model. The thesischoosed the ZigBee module to achieve the goal of positioning, which is a newshort-range、low-rate、low-cost and save-power wireless network technology. Zigbeeis fit for multipath and tortuous environments, which also can be used in indoorlocation. Besides IEEE802.15.4is one of the new protocol standard in the wirelesscommunication protocol system, which is easy-to use and gained a rapiddevelopment. Based on the characters of ZigBee above, choose Zigbee and thesealgorithms to do the indoor location research will be a subject of great value.Meanwhile today people are more and more dependent on the indoor location.Driven by the reality aquirement, this research will be of great economic benefits forthe market.
