Anti-losing device based on virtual fence and positioning method and purpose thereof

Abstract

The invention relates to an anti-losing device based on a virtual fence, and a positioning method and a purpose thereof. The anti-losing device is characterized in that a server is used for sending IDs (identity) of all base stations forming the virtual fence to a monitoring terminal at fixed time, and the monitoring terminal is used for receiving and storing the IDs, obtaining the ID of the currently connected base station through network communication at fixed time, and comparing with the IDs of the base stations stored in the monitoring terminal, so the monitoring terminal does not need to maintain long-time communication with the server, a GPS (global positioning system) module does not need to maintain the long-time opening state, and only when the IDs of the base stations stored in the monitoring terminal do not contain the ID of the currently connected base station, namely the mobile terminal just enters or leaves the range of the virtual fence, the monitoring terminal starts the GPS function module to position the current position of the monitoring terminal, and sends the current position to the server through a GSM (global system for mobile communication) or a GPRS (general packet radio service) or a 3G (third-generation) network, the alarming is sent to the server, and then the server sends alarming to a monitoring platform. The anti-losing device has the advantages that the consumption of electric energy of the monitoring terminal is greatly reduced, and the working time is prolonged.

Description

technical field [0001] The invention relates to the technical field of positioning monitoring, in particular to a virtual fence-based anti-lost device and its positioning method and application. Background technique [0002] With the continuous development of society and the acceleration of people's life rhythm, more and more young people are unable to monitor the elderly and children in real time due to work. As the elderly are getting older and the children are young, the elderly The consciousness of children is becoming more and more blurred, children are limited by their growth level, domestic children are being trafficked and elderly people are missing, and other incidents continue to occur. In response to the above problems, many monitoring and positioning devices have appeared in the market. The existing monitoring and positioning devices generally use base station or GPS positioning, which can monitor and locate the elderly, children and other easy-to-lose groups to ...

AI Technical Summary

Problems solved by technology

[0003] (1) The existing monitoring and positioning equipment needs to maintain communication and positioning with other devices through the mobile communication network for a long time or through GPS satellite positioning. GPS must be turned on for a long time, so using mobile network communication or GPS positioning for a long time consumes a lot of power , which leads to serious power loss of the positioning equipment itself, which makes the monitoring and positioning equipment unable to be used for a long time. The positioning device is installed on the shoe body to monitor the elderly and children wearing shoes with the positioning device. Smaller shoe body, therefore, the application field of traditional positioning equipment is always limited

(2) Existing monitoring and positioning equipment usually uses base stations or GPS positioning. A single GPS positioning cannot achieve indoor positioning, so it cannot meet the application requirements for monitoring the elderly and children, while a single base station positioning can reduce the positioning accuracy. The height is not high, and the positioning is not accurate, so that the police and other search personnel cannot find it in time, and provide criminals with time to transfer children or the elderly
