Problems solved by technology

[0004] The closest existing technology is the "separation alarm" announced by CN96229539.6, which is composed of a transmitter and a receiver. Its disadvantage is that it cannot be used in a network of multiple transmitters and receivers, the effective distance is short, and the anti-interference performance is low , the versatility is not strong, and the lost person or thing cannot be searched
And the technical scheme that can search for lost people or things in a large scale has not been seen publicly yet

Embodiment Construction

[0029] Fig. 1 is the first embodiment of the present invention, a schematic diagram of a method for alarming children from far away:

[0030] The purpose of this embodiment is to determine whether people (children) are playing in the range of setting, and the information transmitter 1 with built-in bluetooth chip is placed in the trousers pocket of child, regularly outwards transmits the information with characteristic code, characteristic code and information The transmitters correspond one by one, and the mobile phone 2 running the built-in software tool continuously receives the information with the characteristic code, and compares it with the stored characteristic code. If the person has exceeded the set range, the mobile phone will send out an alarm signal (such as vibration, voice, text, etc.) to remind the caregiver.

Abstract

This invention relates to the person and object safety. A info emitter with the inner wireless LAN chip attaches on certain person or object and emits timely the wireless info with a special coding (WISC). A handset carried by the supervisor alarms and awakes the supervisor as soon as it cannot receive WISC. Several handsets can connect together via public net to search the lost person or object. This method is efficient and operable and costs low.

Description

technical field [0001] The present invention relates to an alarm method and device and a search method and system, in particular to a child distance alarm method and device applied to a network search method and system. Background technique [0002] With the rapid development of mobile communication technology, mobile phones are not limited to their inherent calling functions, but also have functions such as sending and receiving messages, e-mails, networking, and cameras. In particular, handheld computers are gradually integrated with mobile phones, such as running WindowsMobile, With the emergence of smart phones with systems such as Symbian, Palm, linux, and blackberry, the communication functions with other devices have been greatly enhanced, such as infrared, Bluetooth, WI-FI, etc. As a kind of portable communication tool, mobile phone is developing towards light, thin, short and small direction day by day, so as to be suitable for carrying. [0003] In our daily life,...
