Embodiment Construction

[0011] The present invention takes mobile equipment terminals such as smart phones and PADs as the bearer, supported by APP application software, takes the daily monitoring and combat command business as the leading role, combines the police geographic information system and related business data, and combines GPS positioning, base station positioning and other auxiliary positioning It uses various means to correlate various related spatial data to form a comprehensive visual daily monitoring and combat command platform, providing support for public security users in efficient, fast, visual combat command and decision-making analysis.

[0012] In places where GPS can be obtained, the positioning is obtained through GPS. In places where the signal is not good, relatively accurate location information is finally obtained by obtaining the base station positioning and corresponding information of the base station and the base station information database to do a certain comparison a...

Abstract

The invention relates to a positioning method based on a mobile police terminal, and the method comprises the steps: obtaining the approximate position information of a terminal in a larger range, judging whether there is a GPS signal or not, calling a PGIS system if there is a GPS signal, and obtaining the accurate position information of the terminal; if there is no GPS signal, acquiring relatedbase station information in the range, calling a base station location library for comparison, and if there is corresponding information in the base station location library, taking the correspondinginformation as accurate location information of the terminal; and if no corresponding information exists, performing triangular calculation to obtain terminal position information. Through combination of mobile police terminal positioning and a police geographic information system, police department related services and geographic information are effectively integrated together, and the positioning rate and accuracy of the police terminal are effectively improved.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a positioning method based on a mobile police terminal. Background technique [0002] In the context of "Internet +", more and more mobile devices such as smartphones and PADs have entered the police environment, and a new generation of mobile police platforms has emerged. Due to the special security of the police terminal, the positioning rate and accuracy of the terminal are low, which cannot meet the needs of daily monitoring and effective, fast and real-time command and dispatch business. Contents of the invention [0003] The purpose of the present invention is to address the above problems, to provide a positioning method based on mobile police terminals, combined with auxiliary positioning means such as GPS positioning and base station positioning, to associate various related spatial data for positioning, and effectively improve the positioning rate of poli...
