Accompanying drawing explanation
Fig. 1 is the structural representation of the burglary-resisting system of mobile terminal of the present invention;
Fig. 2 is the method flow diagram of the theft preventing method of mobile terminal of the present invention.
Embodiment
Below in conjunction with accompanying drawing, further illustrate specific embodiments of the invention.
Principle of the present invention is that the surface electrical capacitance large area by capacitance touch screen changes to realize monitoring alarm.Capacitance touch screen is the conventional touch-screens of our present mobile phones, and its touch principle is to wait conductive body touching capacitance plate surface by finger, forms the variation of the capacitance on capacitance plate surface, thereby navigates to finger touches behavior.Yet occurring in nature also has other conductive medias also can cause the variation of touch screen surface capacitance, and for fear of the generation of false touch, capacitance plate is provided with threshold value, only have the variation of capacitance to surpass threshold value and just can regard as touch behavior.The said capacitance variation of this programme is all the variation below threshold value, therefore can not cause the false touch of mobile phone.
As shown in Figure 1, for realize a kind of anti-theft device embodiment of guarding against theft for mobile terminal by touch-screen.The anti-theft device of this mobile terminal comprises: touch-screen 1, capacitance detection module 2, main control module 3 and alarm module 4.
Whether touch-screen 1 in real time induction mobile terminal is placed in an accommodation space, when mobile terminal is positioned at accommodation space, touch-screen 1 can contact or not contact the object in accommodation space inwall or accommodation space, and its capacitive environment value can change, and is stable at a scope.And work as mobile terminal, leave accommodation space, the capacitive environment value of its touch-screen 1 can produce acute variation.In practice, when carrying mobile terminal, accommodation space can be the space that pocket or bag etc. can holding movable terminals.
Capacitance detection module 2 input ends connect touch-screen 1, the capacitance variation of real-time detection touch-screen 1.
Main control module 3 input ends connect the output terminal of capacitance detection modules 2, receive the capacitance variation of the touch-screen 1 of surveying gained, judge whether the capacitive environment value of touch-screen 1 has acute variation, if output alarm signal.
Alarm module 4 input ends connect the output terminal of main control module 3, and when the capacitance acute variation of touch-screen 1, main control module 3 is to alarm module 4 output alarm signals, and 4 of alarm modules carry out Real-time Alarm.
The invention also discloses a kind of mobile terminal, this mobile terminal includes the burglary-resisting system of above-mentioned mobile terminal.Further, this mobile terminal can be mobile phone.
As shown in Figure 2, be the embodiment of the theft preventing method of a kind of mobile terminal of the present invention, the method includes the steps of:
Step 1, mobile terminal are placed into an accommodation space for the first time, in the article-storable space such as the pocket when carrying, bag, sack.Touch-screen can large area generation capacitance variation.Detectable now its touch-screen that obtains of mobile terminal can produce the capacitive environment value in a range of stability, this stable capacitive environment value is prestored as electric capacity reference value, when mobile terminal Detection capacitance value is in this electric capacity reference value, judge that it is arranged in accommodation space.This electric capacity reference value also compares for the touch-screen capacitance with Real-Time Monitoring gained, to judge whether acute variation.
When concrete use, when reference-calibrating value, if mobile terminal, in anti-theft state, may trigger burglar alarm, can be by the load module of mobile phone, the switch of sounding all clear.
Step 2, in daily use, mobile terminal is put into the accommodation spaces such as pocket, can judge whether needs opening anti-theft alarm, if opening anti-theft alarm enters in anti-theft state, jumps to step 3, if not, normally uses mobile phone.
Wherein, mobile phone is in pocket time, guarantee that this face of handset touch panel is pasting the antitheft effect of thigh direction guarantee best, although between touch-screen now and thigh across trousers, but can there is capacitance, must change, and the capacitance variation of bulk area during variation now, with hand value, tap complete difference.
Step 3, at routine use, mobile terminal is put into after accommodation space to the electric capacity reference value that mobile terminal self calibration is default.
The capacitive environment value of capacitance detection module 2 its touch-screens of Real-Time Monitoring of step 4, mobile terminal.
Step 5, main control module 3 receive capacitive environment value in real time, whether the capacitive environment value that judges the touch-screen of mobile terminal produces acute variation,, now whether the difference of the electric capacity reference value of the representative of the detected capacitance of touch-screen and record in accommodation space surpasses predetermined threshold value.If so, judge that mobile terminal leaves accommodation space, jumps to step 6; As no, jump to step 4, continue monitoring.
In whole antitheft process, mobile terminal no matter in or while leaving accommodation space, the capacitance variation of touch-screen is all less than the capacitance variation threshold value that default mobile terminal is judged to be the behavior of touch-screen touch operation, has avoided the generation of maloperation.
The alarm module 4 of step 6, mobile terminal carries out alarm.
Step 7, judge whether to remove burglar alarm, if so, close warning, normally use mobile phone, if not, continue to report to the police, avoid theft to occur, complete the function of burglar alarm.
Although content of the present invention has been done detailed introduction by above preferred embodiment, will be appreciated that above-mentioned description should not be considered to limitation of the present invention.Those skilled in the art, read after foregoing, for multiple modification of the present invention with to substitute will be all apparent.Therefore, protection scope of the present invention should be limited to the appended claims.
