Abstract

The present application discloses a long-distance wide area network positioning method, device, equipment and storage medium. The present application receives the target signal strength indication data at the target point; uses a classification algorithm to determine the target area block corresponding to the target signal strength indication data; The preset random forest positioning model set determines the target random forest positioning model corresponding to the target area block, and the preset random forest positioning model set is a set of random forest positioning models corresponding to each area block; using the target The random forest positioning model performs positioning analysis on the target signal strength indication data to obtain the positioning data of the target point, which can realize high-precision positioning of a long-distance wide area network and improve positioning efficiency at the same time.

Description

technical field [0001] The present invention relates to the field of positioning, in particular to a long-distance wide area network positioning method, device, equipment and storage medium. Background technique [0002] With the continuous development of the Internet of Things, there are more and more applications based on device location information, such as animal tracking in smart ranches. Most of the current mainstream positioning technologies are based on GNSS (Global Navigation Satellite System, Global Navigation Satellite System), Bluetooth, GSM (Global System for Mobile communications, Global System for Mobile Communications) base stations, and LoRa communications. However, in the prior art, GNSS cannot be used indoors when objects are blocked; Bluetooth coverage is small, and large-scale positioning cannot be achieved; GSM positioning equipment has high power consumption; LoRa (Long-distance Wide Area Network) communication technology is a However, at present, the...
