Abstract

The invention discloses a positioning method based on a WiFi wireless network. The positioning method comprises offline stage processing and online stage processing. The offline stage processing is that signal intensity of reference points is acquired and stored in a database so that a fingerprint database is acquired. The online stage processing is that weight is arranged according to instability of WiFi signal intensity, candidate ranges are limited according to moving tracks of moving objects, and positions of the moving objects are confirmed in combination with the fingerprint database. When the moving objects are positioned, instability of WiFi signal intensity and the moving tracks of the moving objects are fully considered so that a problem of low positioning accuracy caused by instability of WiFi signal intensity is solved, and thus positioning accuracy is enhanced.

Description

technical field [0001] The present invention relates to wireless positioning technology, in particular to a positioning method based on WiFi wireless network. Background technique [0002] People always hope that the electronic devices around them can sense the environment and automatically take actions that meet the needs of users according to changes in the environment. IDC (Internet Data Center) predicts that the global sales of smart devices will reach 1.1 billion this year, and by 2016, the global sales will double to 2 billion. There are indications that the major barriers preventing people from leaping from the "personal computing era" to the "ubiquitous computing era" have collapsed. There are indications that the major barriers preventing people from leaping from the "personal computing era" to the "ubiquitous computing era" have collapsed. In ubiquitous computing, devices need to be able to sense the environment, rather than user input. Local area wireless netwo...
