AI Technical Summary

Technical Problem

The prior art fails to fully consider the complex impact of indoor environmental category differences on signal propagation in indoor personnel positioning, resulting in limited positioning accuracy and poor stability.

Method used

By obtaining wireless intercom communication signals and indoor environment categories, key parameters are extracted and data preprocessed, analyzing whether there are abnormalities in the data, and selecting a suitable positioning algorithm for position calculation based on the mapping relationship between indoor environment categories and positioning algorithms. If there is an exception, analyze the exception type and determine the processing strategy based on the correspondence between the exception type and the mobile device's mobile processing strategy.

Benefits of technology

It improves the accuracy and adaptability of indoor personnel positioning, and can quickly and accurately determine personnel positions in complex and changeable indoor environments, reduce positioning delays, and improve the stability and reliability of the system.

Abstract

The invention relates to an indoor personnel positioning method and system based on wireless talkback communication, and the method comprises the steps: analyzing whether key parameters after data preprocessing are abnormal or not according to key parameter data after data preprocessing and a preset parameter abnormality judgment method; if not, the positioning algorithm adopted this time is analyzed and determined according to the mapping relation between the indoor environment category and the positioning algorithm; according to the key parameter data after data preprocessing and a positioning algorithm adopted this time, position calculation is carried out to determine position coordinates of the personnel; and if yes, analyzing the abnormal parameter type, analyzing and determining a mobile processing strategy of the mobile device according to a corresponding relation between the abnormal parameter type and the mobile processing strategy of the mobile device, executing the mobile processing strategy, and analyzing whether the key parameter is abnormal or not by adopting a preset parameter abnormality judgment method in real time. The method has the following effect that the indoor personnel positioning accuracy is improved.
