AI Technical Summary

Technical Problem

The existing RSSI positioning method suffers from signal attenuation over long distances, resulting in large positioning errors, and the computational burden is placed on the terminal, limiting its application scope.

Method used

The server receives the terminal's positioning request, notifies multiple access points to count the number of detection frames, uses the packet number gradient model to convert it into distance features, and uses the triangulation positioning algorithm to calculate the terminal position, reducing the terminal's computing burden and improving positioning accuracy.

Benefits of technology

It achieves more accurate indoor positioning at long distances, reduces the computing burden of the terminal, and improves positioning accuracy.

Abstract

An indoor positioning method comprises: a server receiving an indoor positioning request including a terminal identifier from a terminal; the server notifying multiple access points of the terminal identifier and receiving positioning data from a first number of the multiple access points; and calculating coordinate information of the terminal's location based on the coordinate information of each of the first number of access points and the positioning data, and returning the coordinate information to the terminal. The present invention also provides a system, server, and computer-readable storage medium for implementing the indoor positioning method. The present invention can achieve indoor positioning that is not based on received signal strength.
