Embodiment Construction

[0017] The specific implementation manners of the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation manners described here are only used to illustrate and explain the embodiments of the present invention, and are not intended to limit the embodiments of the present invention.

[0018] LoRa-based Netwok (LoRa network, or Low-Power Wide Area Networks), is a new type of low-power self-deployment network, different from the traditional Internet of Things, the future will be IoT (Internet of Things, Internet of Things) Basic deployment of the network. The LoRa network has many unique features, including: (1) a new type of wireless communication system; (2) can adopt a variety of flexible modes such as end-to-end (Class A), end-to-base station (Class B); (3) due to the use of The unlicensed free frequency band (less than 1GHz) is used, and the optimized algor...

Abstract

The embodiment of the invention provides a method for indoor positioning of a LoRa network and a machine readable storage medium, and belongs to the field of the communication. The method comprises the following steps: collecting LoRa environment data in a room based on the LoRa network; training a migration learning model based on the LoRa environment data and a historic database, wherein the historic database comprises the environment data collected in the room by other wireless networks except the LoRa network and the indoor location information corresponding to the environment data; and determining the indoor location information corresponding to the LoRa environment data based on the trained migration learning model and the LoRa environment data. Therefore, the indoor positioning based on the LoRa network is realized.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method for indoor positioning of a LoRa network and a machine-readable storage medium. Background technique [0002] Positioning technology is a method of determining the physical location of a target being tracked. Due to the importance of location information, currently there are various technologies and methods for providing or detecting indoor or outdoor location information. More mature methods include outdoor positioning systems represented by GPS and Beidou, and indoor positioning systems represented by UWB, Bluetooth, and Wi-Fi. Positioning technology can also provide location information for other existing applications to improve the accuracy of application services. [0003] In the prior art, both GPS and Beidou are aimed at the outdoor environment, and it is difficult to accurately locate indoor targets indoors due to the problem of signal occlusion. UWB, Bluetoo...
