Problems solved by technology

There are also many algorithms for routing-based server-side indoor positioning, such as triangular positioning based on distance, etc., but there is no complete set of systems for indoor positioning, and the accuracy of positioning is relatively poor in previous studies.
There will be two extreme results, the cost of high accuracy is high, and the positioning accuracy of low cost is not high

Embodiment

[0027] Such as figure 1 as shown, figure 1 Some of the abbreviations are Positioning Algorithm Module (PAM), which is mainly responsible for positioning algorithm affairs, Data Adapter Module (DAM), which is mainly responsible for data format adaptation, and Configuration Management Module (CMM). ) is mainly responsible for system configuration, sampling program (Sampling App) is mainly responsible for client fingerprint training and router cluster (AP cluster) is mainly responsible for sniffing network signal transactions in the air and DB (database). The numbers represent the process.

[0028] In the fingerprint training phase, the map needs to be prepared first, including uploading the map, gridding the map, adding router locations, and generating fingerprint points.

[0029] Then pull the map that needs to be checked from the server through the mobile phone terminal (the mobile app in the mobile phone). Such as figure 1 The process, first the AP (router) cluster transm...

Abstract

The invention discloses an indoor server locating method based on routers. WI-FI is used as a characteristic value to make good use of the existing mobile phone equipment, no direct participation of a client is required in the server locating, and a dynamic locating system is obtained by using a fingerprint algorithm and some filtering algorithms. According to the indoor server locating method disclosed by the invention, a small number of routers are used for carrying out indoor locating on a plurality of devices in a locating area, the locating is quite accurate, the error is small, and the dynamic locating effect is good due to a filtering mechanism.

Description

technical field [0001] The invention relates to a router-based server indoor positioning method. Background technique [0002] At present, there are many studies on indoor positioning, and different characteristic values ​​can be selected, such as WI-FI signal strength, magnetic field, Bluetooth or infrared rays, etc. In addition, there are two research directions according to whether the client is involved, one is indoor positioning with client participation, and the other is indoor positioning where the client does not need to participate and sniffs WI-FI signals through a router. There are also many algorithms for routing-based server-side indoor positioning, such as distance-based triangulation, etc., but there is no complete set of systems for indoor positioning, and the accuracy of positioning is relatively poor in previous studies. There will be two extreme results, the cost of high accuracy is high, and the positioning accuracy of low cost is not high. Contents of...
