“…The traditional switching algorithm is realized by setting the parameters of fixed point switching [19], switching within the effective area [20] or judging the number of base stations of UWB system, the number of satellites of GNSS system [5], signal strength [21], etc. There are problems such as frequent switching or untimely switching, which do not achieve good results.…”

“…The 𝐹 𝑈 and 𝐹 𝐺 in (20) denote the sample standard residuals of the UWB and GNSS systems, respectively, and 𝑛 is the power of the residual. The larger the value of 𝑛, the sharper the discriminative effect on the confidence of the two systems, and the more the confidence of the two systems converges to 0 or 1 after normalization, and the value interval of 𝑛 in this system is [0.5,1].…”

This paper proposes a positioning mode switching algorithm for positioning tags based on the joint system confidence and motion trend. The algorithm is based on establishing the position estimation confidence of the UWB/GNSS system and the confidence fusion seamless positioning algorithm of particle filtering, which uses a combination of hard and soft switching to achieve seamless positioning. Through the experiment, the positioning accuracy of the positioning tag is measured to be 50.6cm and 56.4cm in the indoor area and the stationary state in the mixed area, with the standard deviation less than 32cm and less than 36cm, respectively; the walking trajectory is stable and clear in the indoor and outdoor dynamic test, and the positioning switching effect is obvious.

Indoor location and intelligent control system can bring convenience to people’s daily life. In this paper, an indoor control system is designed to achieve equipment remote control by using low-energy Bluetooth (BLE) beacon and Internet of Things (IoT) technology. The proposed system consists of five parts: web server, home gateway, smart terminal, smartphone app and BLE beacons. In the web server, fingerprint matching based on RSSI stochastic characteristic and posture recognition model based on geomagnetic sensing are used to establish a more efficient equipment control system, combined with Pedestrian Dead Reckoning (PDR) technology to improve the accuracy of location. A personalized menu of remote “one-click” control is finally offered to users in a smartphone app. This smart home control system has been implemented by hardware, and precision and stability tests have been conducted, which proved the practicability and good user experience of this solution.
