Alarm method and system

Abstract

The invention discloses a warning alarm method and the system thereof. The externally arranged Bluetooth module is matched with a mobile phone through the Bluetooth to establish corresponding connection; the Bluetooth module is communicated with the mobile phone at the time when the mobile phone starts up; the signal intensity between the Bluetooth module and the mobile phone is checked every other preset time; if the distance between the Bluetooth module and the mobile phone extends, the warning alarm message is sent out when the signal intensity is lower than the preset value. By adopting the technical proposal of the invention, the invention not only realizes the warning alarm in certain distance from the mobile phone, but also realizes the dual warning alarm of the mobile phone and the Bluetooth module; thereby preventing the mobile phone from being stolen and losing, as well as preventing other articles from being stolen and losing.

Description

technical field [0001] The invention relates to the technical field of bluetooth communication, in particular to an alarm method and system. Background technique [0002] With the rapid development of mobile communication technology, mobile phones have become communication devices that people carry with them in their daily lives. Because the price of mobile phones is relatively high, how to prevent mobile phones from being stolen or lost has become a technology that people are very concerned about. [0003] At present, the main anti-theft or anti-lost technical solution is to install anti-theft software inside the mobile phone. The anti-theft software mainly has the following functions: one is that after the owner installs and sets password protection, once the mobile phone is stolen or lost, the software can not only quietly The new card number of the mobile phone holder will be sent to the mobile phone you specify, and the owner can send a control command to lock the mobi...

[0006] But at present this technical scheme has the following disadvantages: it can't take effect immediately when the stolen or lost behavior occurs, and it can't actually play a protective role; the criminal will turn off the mobile phone at the first time after stealing the mobile phone, so the anti-theft function usually needs to be activated after the mobile phone is stolen. It will take a long time after the owner loses the mobile phone, it will be effective when the criminal uses it again, but the chance of successfully recovering it is very small at this time; people who have some common sense of mobile phone software can easily delete the anti-theft software and make the anti-theft function invalid; Some additional functions, such as restricting the function of the mobile phone, can only prevent the thief from continuing to use the mobile phone, and will not help the owner to find the mobile phone; and there is no scalability
