The Improvement And Implement Of The Indoor Positioning Technology Based On Bluetooth In Exhibition Environment

The indoor positioning technology which provides much convenience in people's life is one of the key technologies to realize modern exhibition. Because of high and empty, the exhibition pavilion is quite different from the ordinary indoor environment, so the use of the traditional indoor positioning technology positioning will exist in the lower position accuracy. This paper mainly studies how to improve the accuracy and the stability of the indoor positioning technology which using in exhibition environment.In this paper, we have obtained the high distribution of the Bluetooth signal source in the environment of the exhibition, so as to determine the best height of the source and calculate the effective transmission distance. Because of the impact of RSSI (Signal Strength Indication Received received signal strength indicator), the paper focuses on the characteristics of the proposed method, which can be used to improve the positioning accuracy of the weighted triangle centroid localization algorithm. The basic content of this method is as follows:firstly, according to the traffic flow density, three kinds of high school and low density are divided into three kinds of RSSI ranging parameters, which are used to calculate the flow density. Finally, the algorithm and the exhibition location system are realized in the Bluetooth environment, and the feasibility of the new algorithm is verified by experiments. The experimental results show that the weighted triangle centroid localization algorithm can make the indoor location more accurate and more stable in the exhibition environment.
