Abstract

The invention provides a location method, device and terminal, and relates to the field of communication. In order to solve the problem that a location manner cannot be selected in a self-adaption manner in the current virtual fence location system, the method comprises the steps of monitoring a geological position of the terminal, and calculating the distance between the terminal and a preset virtual fence; determining the location manner and a corresponding location time interval according to the distance between the terminal and the virtual fence and a preset distance threshold value; adopting the location manner for location after the location time interval. According to the location method, device and terminal, a proper location manner can be selected in a self-adaption manner according to location needs.

Description

technical field [0001] The present invention relates to the communication field, in particular to a positioning method, device and terminal. Background technique [0002] Virtual fence technology is a security monitoring technology based on positioning. Its principle is to use various positioning methods to obtain the location information of the navigation terminal, calculate the distance between the navigation terminal and the boundary point of the fence, and judge whether the navigation terminal is in the fence. The field of application of this technology is the safety monitoring of children, the elderly and vehicles. [0003] The virtual fence system in the prior art is only based on GPS positioning technology, with high positioning accuracy and accurate alarm. However, during the monitoring process, the virtual fence system based on positioning technology requires the terminal to initiate positioning continuously, so it is necessary to keep the GPS hardware continuously ...
