Abstract

The invention relates to a situation-related indoor positioning method and system. The method comprises the following steps of (1) acquiring environment information through intelligent handheld equipment in real time; (2) obtaining position sets of a target by a conventional indoor positioning method according to the environment information; (3) obtaining the current situation in which the target is positioned by a situation judgment method according to the environment information; (4) screening the position sets according to a situation result obtained in the step (3) to obtain a final positioning result, and displaying the final positioning result; and (5) judging whether a target satisfaction instruction is received, if so, uploading the real-time position information and situation object information to a background processing device through a wireless network, and updating the situation object information. The system comprises the intelligent handheld equipment, the background processing device and a plurality of wireless receiving nodes. Compared with the prior art, the method and the system which are disclosed by the invention have the advantages of high positioning precision, low arrangement cost, excellent user experience and the like.

Description

technical field [0001] The present invention relates to a positioning method and system in the field of mobile communication, in particular to a context-related indoor positioning method and system. Background technique [0002] In recent years, indoor positioning systems have attracted more and more attention because they provide services based on location information in indoor environments. Although the Global Positioning System (GPS) performs very well in outdoor environments, it does not work indoors because GPS signals cannot penetrate indoors. Therefore, accurate indoor positioning systems are still a missing but important part of wireless mobile applications, and are increasingly attracting widespread attention from all parties. Let's talk about their implementation principles: [0003] Indoor positioning systems are used to provide location information of individuals and devices. Accuracy and computational convergence time are considered to be the most important f...
