Problems solved by technology

[0006] However, in practical applications, the inventors of the present invention found that the existing indoor positioning methods often have serious positioning deviations in some occasions, such as supermarkets with multiple rows of shelves. The reason is that the current Bluetooth positioning methods usually The positioning accuracy can only reach 3-5 meters. However, the distance between each row of shelves in the supermarket is within 3 meters. Therefore, the positioning accuracy cannot meet the accuracy requirements of supermarket positioning. other aisles in the row, resulting in serious positioning deviation and poor user experience

Abstract

The invention discloses an indoor positioning method and system based on a Bluetooth beacon group. The method comprises the steps of acquiring beacon data output, according to a positioning point, byeach Bluetooth beacon in each indoor bean group, wherein the indoor space is divided into multiple spatial areas, and Bluetooth beacons in the same spatial area are in the same beacon group; accordingto the beacon data output by each Bluetooth beacon, determining a beacon group of a spatial area in which the positioning point is; and according to the beacon data output by the Bluetooth beacon ofthe determined beacon group, determining coordinates of the positioning point. Through adoption of the method and system, large positioning deviation is prevented, and the user experience is improved.

Description

technical field [0001] The present invention relates to the field of bluetooth technology, in particular to an indoor positioning method and system based on bluetooth beacon grouping. Background technique [0002] With the popularity of smart phones, Bluetooth has become the standard configuration of mobile phones, making the application of Bluetooth technology a possibility for general promotion. In the indoor positioning industry, the technology of using Bluetooth to realize location service is already known. [0003] Bluetooth is a wireless technology standard that can realize short-distance data exchange between fixed equipment, mobile equipment and building personal area networks (UHF wireless radio waves in the ISM band of 2.4-2.485GHz), and Bluetooth positioning mainly uses Bluetooth 4.0 beacon broadcast function. [0004] First of all, Bluetooth beacons (beacons) continuously send beacon broadcast messages (messages include transmission power). After receiving the ...
