Research And Design Of Wireless Positioning System Based On ZigBee Technology

Wireless positioning in automation control,navigation,etc.The use of the common,such as the typical GPS satellite positioning technology has been very mature,but in smaller or indoor wireless location applications,there is need to improve,such as the accuracy of positioning in actual use,cost,power consumption,etc.Have not reached the expectation of people.Recently,the new ZigBee bee swarm technology has the advantages of low energy consumption,low investment and high extensibility,which solves some engineering problems of wireless positioning.Based on ZigBee bee colony technology,this paper designs and implements a wireless positioning system.Three important components of the system design are: reference node,controller and the desired location mobile node.The parameters used for measurement during positioning are RSSI indicating the strength of received signal.The realization of the communication part of the system includes the communication process of the communication device,the positioning communication specification,the communication message format and the interactive process.Finally,based on the CC2530 positioning computing engine,the indoor positioning performance of the engine is tested and evaluated.The test and evaluation results show that the system design meets the requirements of wireless positioning and has certain extensibility,which contributes some basic application data to the research and implementation of wireless positioning..
