Embodiment 1

[0027] Embodiment 1, referring to FIG. 1 , this embodiment specifically describes an implementation structure of the active anti-lost system for handheld devices. Wherein, the handheld device mainly includes: an input module, a main processor, a short-range wireless communication module, a signal strength detection module, and an alarm circuit; and the short-range wireless communication device communicating with it includes a short-range wireless communication module, Main parts such as MCU and alarm circuit.

[0028] The handheld device receives the set value of the safety distance input by the user through the input module, and then converts it into a corresponding data signal and outputs it to the main processor; The comparison table of the corresponding relationship between the distance between devices and the signal strength, and then determine the threshold value of the signal strength, and define the threshold value as the threshold value set by the user and transmit it...

Embodiment 2

[0035] Embodiment 2, as shown in FIG. 3 , this embodiment takes a mobile phone as an example to specifically describe one of the circuit composition forms of a handheld device, which mainly includes: an input module, a baseband chip, an audio control module, a speaker, a microphone, and a camera (Camera sensor). ), camera chips, short-range wireless communication modules and NAND FLASH, SDRAM memory, etc. Among them, as the core unit inside the mobile phone, the baseband chip completes the task of the main processor in the handheld device, receives the radio frequency RF signal transmitted by the base station, and demodulates it into a digital signal and outputs it to the audio control module to control the speaker output. Ringtone of incoming call or voice of the other party; after the voice signal sent by the mobile phone user is received by the microphone, it is converted into a digital signal under the action of the audio control module and transmitted to the baseband chip ...

Abstract

The invention discloses an active anti-loss system and an anti-loss method for a handheld device, comprising a handheld device and a short-distance wireless communication device for communicating with the handheld device, wherein the handheld device or the short-distance wireless communication device output an alarm when detecting that the signal intensity in between reaches a set threshold value, so that when moving away from the short-distance wireless communication device, the handheld device output an alarm to remind an owner of the loss of the handheld device. The method conducts real time detection of the distance between the handheld device and the short-distance communication device such as a Bluetooth device, an infrared device, etc. and actively outputs an alarm when the distance goes beyond a threshold value to remind the owner to prevent the handheld device from being lost, thereby reducing the risks of losing the handheld device. The active anti-loss method can not only prevent the handheld device from being stolen, but also prevent the handheld device from being stolen due to the carelessness of the owner.

Description

technical field [0001] The invention belongs to the technical field of equipment safety protection, and in particular relates to a method and system for preventing the loss of a handheld device. Background technique [0002] With the continuous development of handheld devices, more and more functions can be realized, not only becoming a multimedia entertainment tool for users, but also having the function of saving user profile information. Especially mobile communication handheld devices like mobile phones have not only brought flexibility and convenience in use to users, but also brought huge wealth to people. The loss of a handheld device is not only an economic loss for the owner, but the loss of the data stored in it may be even greater. Therefore, how to realize the anti-lost function of the handheld device has become a problem that developers and consumers pay more and more attention to at present. [0003] At present, anti-lost methods applied to mobile phones are ...
