Problems solved by technology

[0002] The problem of missing children is a catastrophic disaster for every family. It not only causes family misfortune, but also becomes a serious social problem, causing a certain degree of social panic and increasing social instability. Seriously affect the harmonious development of society; in addition to some being snatched and abducted, a large part of them are due to the fact that children are separated from their guardians in crowded or other occasions, causing children to go missing, and because they are not found in time and are not carried out in time. Search, resulting in missing children
[0003] There are also some anti-lost devices for children, but most of these devices are based on GPS positioning to monitor the current location of children, thereby preventing children from getting lost. Because GPS positioning is easy to be inaccurate or cannot be accurately positioned when the child is lost in a building. After that, it is impossible to locate quickly and accurately, and miss the best time to find
In addition, most child prevention devices use GPS for positioning, allowing traffickers to use GPS jammers to disable child positioning devices
[0004] In addition, the existing anti-lost devices for children generally have a single function, a relatively large structure, and a relatively high degree of recognition

Embodiment 1

[0123] The anti-lost system for children in this embodiment includes an anti-lost terminal, a mobile terminal,

[0124] The anti-lost terminal includes a danger alarm unit, including an alarm time setting module, a Bluetooth search module, and an alarm output module,

[0125] Wherein the alarm time setting module is used to set the time period during which the alarm data can be uploaded;

[0126] The Bluetooth search module is used to search for a matching mobile terminal when the three-axis acceleration sensor draws / walks out of a predetermined shape through the feet.

[0127] If a matching mobile terminal is found, it will not be processed;

[0128] If no matching mobile terminal is found, the alarm output module sends an alarm message to the mobile terminal through the SIM card.

[0129] The predetermined shape includes a straight line trajectory, a turning angle trajectory, and a return trajectory.

[0130] In this embodiment, the method for preventing children from get...

Embodiment 2

[0145] Batteries for wearables need to last at least a day, as children's wearables need to be lightweight and small.

[0146] The anti-lost system for children in this embodiment includes an anti-lost terminal and a mobile terminal;

[0147] The anti-lost terminal also includes a power saving unit, the motion determination unit includes a motion trajectory module, the motion trajectory module is a three-axis acceleration sensor, and the communication unit includes a Bluetooth module;

[0148] The three-axis acceleration sensor detects the user's motion data, and transmits the data to the mobile terminal through the communication unit;

[0149] The power saving unit includes an upload time setting module and an upload frequency setting module; the upload time setting module is used to set the time period for the communication unit to upload data to the mobile terminal, and the upload time period is divided into idle time Time period, time period during busy hours; upload freq...

Embodiment 3

[0165] On the basis of Embodiment 1, the anti-lost system for children in this embodiment, the anti-lost terminal also includes: a movement companion time statistics unit, the three-axis acceleration sensor detects that the user performs a predetermined action and / or detects that the user's exercise index reaches motion threshold, the Bluetooth module of the anti-lost terminal sends a connection start signal to the mobile terminal, and the mobile terminal records the time when the wearable device is connected to the mobile terminal.

[0166] The Bluetooth module of the anti-lost terminal sends a connection start signal to the mobile terminal,

[0167] If a mobile terminal is connected, the wearable device is connected to the mobile terminal via Bluetooth;

[0168] If at least two mobile terminals are connected, the wearable device performs a time-sharing Bluetooth connection with each mobile terminal.

[0169] In this embodiment, the mobile terminal is the mobile phone carrie...

Abstract

The invention discloses an anti-lost system and an anti-lost method for children and is mainly designed for sending out alarm information quickly and conveniently when the children are in danger. The anti-lost system comprises an anti-lost terminal and a mobile terminal, wherein the anti-lost terminal at least comprises a triaxial-acceleration sensor unit and a danger alarm unit; the danger alarm unit comprises an alarm-time setting module, a Bluetooth search module and an alarm output module; the alarm-time setting module is used for setting a period of time when the anti-lost terminal can upload alarm data to the mobile terminal; the Bluetooth search module is used for searching the matched mobile terminal when the triaxial-acceleration sensor unit obtains a preset shape drawn / walked by single foot or a preset figure is drawn / walked by double feet, if the matched mobile terminal is not searched, the alarm output module sends out alarm information.

Description

technical field [0001] The invention relates to a system and method for preventing children from getting lost. Background technique [0002] The problem of missing children is a catastrophe for every family. It not only causes family misfortune, but also becomes a serious social problem, causing a certain degree of social panic and increasing social instability. Seriously affect the harmonious development of society; in addition to some being snatched and abducted, a large part of them are due to the fact that children are separated from their guardians in crowded or other occasions, causing children to go missing. The search resulted in the disappearance of the child. [0003] There are also some anti-lost devices for children, but most of these devices are based on GPS positioning to monitor the current location of children, thereby preventing children from getting lost. Because GPS positioning is easy to be inaccurate or cannot be accurately positioned when the child is ...
