The Research Of Scence Fingerprint Locatiion Based On The ZigBee Technology

As the development of computer technology and the needs in people's daily life and work and production,the location service of human and things becomes more important. This article's main work is to research and design a location method ,higher location accuracy,lower cost and power consumption, which can be used in the real life and produciton.The ZigBee technology based on the standard of IEEE 802.15.4 is a new short distance wireless communication technology with the features of low cost,power consumtption and speed.As the development of ZigBee techonology,it has been used widely in these areas of intelligentize house,industry robotization,medical nurse without human and so on.And the location application based on the ZigBee's wireless network is getting more attention from more aspects.This article's main resarch work is on the wireless location method based on the ZigBee technology. The main research word and achievement is as follows. Firstly , analyse and do reaserch on the key aspects of the ZigBee network and the ZigBee net's work process and principle. At the other hand, reaserch on some existing location methods and summarize theses methods's main features. Focusing on the method based on the Received Signal Strength Identification(RSSI) and the scene fingerprint method,and a mixed location method compromised these two location method named RSS scene fingerprint location method. Then,reseach and design a location system,using the CC2430/2431 CMOS chip module to realize the location system's hardware module,and design the system's kinds of nodes' software.Lastly,do some experiment tests on the location system used location method invented by this article in school's laboratory.By the this article's experiment tests,it indicates that this location method basicly meets the location system's basic demands of low cost,power consumption,and being easily realized. At the same time,summarize this article's work and take some deficiencies and do some plans on the future reasarch work.
