Wi-Fi Bluetooth integrated base station positioning system

Abstract

The invention relates to a technology which uses a novel Wi-Fi 802.11mc ranging protocol and a Bluetooth integrated base station to determine the location of a user. The user can measure the distancebetween user equipment and the base station through Wi-Fi FTM. A telegraph text broadcasted by the base station Bluetooth is analyzed to acquire the precise coordinate of the base station, so as to realize the real-time, high-precision, high-availability positioning system. A Wi-Fi AP supports the latest IEEE802.11mc ranging protocol. The distance from the user equipment to an AP point can be measured in real time, and at the same time the base station location information of the Bluetooth real-time broadcast can be acquired. The user equipment may be a smart terminal including a Wi-Fi moduleand a Bluetooth module, such as a smart phone, a wearable device and an embedded module, and needs to support Bluetooth 4.2 (and above) and the IEEE 802.11mc protocol. The system can realize indoor and outdoor seamless positioning without changing the user's habits and increasing the hardware cost of the user, and has the advantages of accurate and reliable positioning result and high availability.

Description

Technical field [0001] The invention patent relates to electronic information technology and indoor navigation and positioning technology. Specifically, the Wi-Fi FTM function and the Bluetooth broadcast function are integrated to form an integrated base station. The entire positioning system is composed of three or more integrated base stations. The user terminal obtains the base station and relevant information required for positioning by capturing and decoding the navigation messages issued by the integrated base station, and obtains the real-time distance from the user terminal to the base station, and calculates Obtain high-precision and highly available indoor location coordinates. Multiple base stations can be networked automatically, and the base stations have automatic signal calibration and communication functions. Background technique [0002] Positioning is one of the core technologies for location services, Internet of Everything, artificial intelligence and future...
