Abstract

The embodiment of the invention provides an indoor positioning method and system based on Bluetooth communication and a BLE chip. The method comprises the steps: arranging and installing beacons and array antennas in a positioning area; according to the beacons, establishing a fingerprint database, wherein the fingerprint database comprises associated information of signal fingerprints and coordinate positions; and determining a target position in the positioning area according to the beacons and / or the array antennas. In the embodiment of the invention, position fingerprint positioning and multi-antenna positioning are combined, the target position is determined by preferentially using multi-antenna positioning, and when the target is out of the coverage range of the multi-antenna positioning, the target position is determined by using the position fingerprint positioning. The influence of obstacles in a specific place on multi-antenna positioning can be eliminated; the problem that the fingerprint positioning effect is poor in the area position with large environment change is solved. The size of the fingerprint database is reduced as much as possible under the condition of ensuring the positioning precision.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a Bluetooth communication-based indoor positioning method, system and BLE chip. Background technique [0002] Indoor positioning refers to the realization of position positioning in the indoor environment. It mainly adopts wireless communication, base station positioning, inertial navigation positioning, motion capture and other technologies to form a set of indoor position positioning system, so as to realize the positioning of people and objects in the indoor space. location monitoring. [0003] In the related art, common indoor positioning methods include position fingerprint positioning and multi-antenna positioning. [0004] Among them, the position fingerprint positioning includes two stages: the first stage is the training / offline stage, the main work is to collect the signal characteristic parameters of each reference point in the required positioning...
