An AOA Indoor Positioning System Based on Bluetooth 5.1

With the increasing demand for indoor positioning, indoor positioning technology has attracted much attention and research in recent years. In order to make the warehouse intelligent, this paper designs and implements an AOA indoor positioning system based on Bluetooth 5.1 to realize the asset positioning in warehouse. This system design mainly includes three parts: Bluetooth beacon, Bluetooth positioning base station and PC software design. It mainly realizes the data communication between the Bluetooth beacon and the Bluetooth positioning base station. The Bluetooth positioning base station realizes the positioning of the Bluetooth beacon through the azimuth angle and transmits it to PC software. The PC software processes the data of Bluetooth base station, completes the coordinate calculation of positioning information, and finally realizes the display of positioning information.
