The embodiment of the invention discloses a kind of electronic equipment theft preventing method, guaranteed that user can find that electronic equipment is stolen, has improved the safety coefficient of electronic equipment in time.
Referring to Fig. 1, show the schematic flow sheet of an embodiment of a kind of electronic equipment theft preventing method of the present invention, the method can be applied in the electronic equipments such as mobile phone, palm PC, panel computer, and this electronic equipment at least comprises the first sensing unit;
This electronic equipment can be external with an audio output unit, with via this audio output unit outputting audio data.
The method of the present embodiment can comprise:
Step 101: the first steering order that audio reception output unit sends;
In the time of the external audio output unit of electronic equipment, audio output unit can send the first steering order to electronic equipment, wherein, this audio output unit has the first button, the instruction that this first steering order produces can be pressed for the first button of audio output unit time.
Step 102: respond described the first steering order, control electronic equipment and enter first mode;
First mode is the antitheft open mode of electronic equipment, and electronic equipment enters after first mode, and when having people to approach or when contacting electronic equipments, electronic equipment can send the indication of reporting to the police, concrete implementation is as follows;
Step 103: utilize described the first sensing unit to obtain the first parameter sensing, and the size of more described the first parameter sensing and first threshold;
Wherein, when user is connected electronic equipment with audio output unit; conventionally electronic equipment can be placed in pocket or bag; between user and electronic equipment, can be separated by clothes or bag; therefore; can utilize the first sensing unit on electronic equipment to obtain the first parameter sensing, and judge whether that according to this first parameter sensing someone approaches electronic equipment.
The first sensing unit is arranged on electronic equipment, and the first parameter sensing gathering can reflect the variation of external environment, and while having people near electronic equipment and unmanned close electronic equipment, the first parameter sensing that its first sensing unit gathers is different; And the concrete position of the first sensing unit can be set according to actual conditions, as be arranged on the one side of electronic equipment display screen or be arranged on the one side that electronic equipment is relative with display screen or be arranged on the surrounding of electronic equipment, with the variation of sensitiveer perception surrounding environment.
When electronic equipment enters after first mode, by utilizing the first sensing unit to obtain the first parameter sensing, and this first parameter sensing and first threshold are compared, wherein, first threshold is predefined for judging whether that someone approaches the standard of electronic equipment.
Step 104: in the time that described the first parameter sensing is more than or equal to first threshold, generate the first reminding data;
Wherein, in the time that the first parameter sensing is more than or equal to first threshold, illustrate that people is near electronic equipment, now, generated the first reminding data;
Step 105: output the first reminding data is to remind the user of electronic equipment.
In the embodiment of the present application, by in the time receiving audio output unit and send the first steering order, control electronic equipment and enter first mode, thereby utilize the first parameter sensing that the first sensing unit obtains to judge whether that people is near electronic equipment, if the first parameter sensing is more than or equal to first threshold, illustrate that people is near electronic equipment, now, remind the user of electronic equipment by generating and export the first reminding data, guarantee that user can find that electronic equipment is stolen, has improved the safety coefficient of electronic equipment in time.
Referring to Fig. 2, show the schematic flow sheet of another embodiment of a kind of electronic equipment theft preventing method of the present invention; The method can be applied in the electronic equipments such as mobile phone, palm PC, panel computer, and this electronic equipment at least comprises the first sensing unit;
