A hybrid alarm positioning method and system

Abstract

The invention relates to a hybrid alarm positioning method, comprising the following steps: when a mobile terminal dials a phone, if it is determined that the dialed number is an alarm number, then try to obtain the current GPS positioning information, and if the GPS positioning information is successfully obtained, the obtained GPS positioning The information is sent to the alarm terminal server; if the acquisition of GPS positioning information fails, search and connect to a specific nearby preset WIFI LAN and mark the alarm logo; if the alarm terminal server does not receive GPS positioning information from the mobile terminal within the set time range , the base station positioning is used to obtain the approximate location of the mobile terminal; all specific WIFI local area networks are queried within the area of ​​the obtained approximate location, and if a specific WIFI local area network is found to be connected to a device with an alarm logo, the specific WIFI local area network is identified The covered area is a possible location area; it can organically combine GPS positioning, base station positioning, and WIFI-assisted positioning to greatly improve positioning accuracy and reliability, thereby improving the efficiency of police dispatch.

Description

technical field [0001] The present invention relates to the technical field of alarm positioning, and more specifically relates to a hybrid alarm positioning method and system. Background technique [0002] At present, there are two positioning methods for simultaneous alarming, one is to use GPS positioning, and the other is to use base station positioning; although the former has high positioning accuracy, it is easily interfered and has relatively poor reliability. Good reliability, but low positioning accuracy. An alarm positioning method that can be considered comprehensively is needed to improve the accuracy and stability of alarm positioning, thereby improving the efficiency of alarming. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a hybrid alarm locating method and a hybrid alarm locating system for the above defects of the prior art. [0004] The technical solution adopted by the present invention to...
