Wireless positioning method for mobile phone terminal

Abstract

The invention belongs to the field of wireless data communication and specifically discloses a wireless positioning method for a mobile phone terminal. The method comprises the following steps of step 1.sorting signal strengths from small to large and solving a percentage probability P(R), a median, a mode and a mean value which are corresponding to each signal strength distribution; step 2.carrying out curve fitting on the signal strength probability distributions and carrying out peak detection on a fitted curve, if two or more of peak values exist, taking the maximum peak value in the curve fitting as a signal strength characteristic value; step 3.if only one peak value exists, carrying out step 4, if two peak values exist, taking the right peak value and carrying out step 8; and step 4.computing a coefficient of skew Cs of the probability distribution. The wireless positioning method for the mobile phone terminal is provided for the technical problem that the limitation is great when a volunteer works and carries out fingerprint positioning on the mean value of RSSI signal characteristic values due to complexity and dynamics of the indoor environment.

Description

technical field [0001] The invention relates to the field of wireless data communication, in particular to a wireless positioning method for a mobile phone terminal. Background technique [0002] With the development of the Internet, more and more people use the Internet, and many people participate in voluntary activities through the Internet, so these people are also called Internet volunteers. Volunteers meet and organize activities through the Internet, from virtual to real activities. All Internet volunteers are self-organized by netizens. They are bottom-up non-governmental organizations. They have two things to do, donate money and materials and donate time. [0003] Volunteers usually work in unfamiliar environments. For example, in some large indoor exhibitions, supporters are usually required to maintain the order of the crowd, and volunteers usually need to walk around the venue during the event. In an unfamiliar environment, it is very important for volunteers'...

AI Technical Summary

Problems solved by technology

[0006] The present invention aims at the technical problem that there is a relatively large error when the average value of the characteristic value of the RSSI signal is used for fingerprint positioning due to the complexity and dynamics of the indoor environment when the volunteers are working, and the technical problem is to provide a wireless positioning method for a mobile phone terminal
