Embodiment
Provide preferred embodiment of the present invention below in conjunction with accompanying drawing, to describe technical scheme of the present invention in detail.
The first embodiment:
Figure 1 shows that the circuit structure diagram of theft preventing mobile terminal in the present embodiment, comprising an infrared LED 1 (light emitting diode), an infrared proximity transducer 2, a loudspeaker 3 and a MCU4 (microprocessor).
Wherein said infrared LED 1 consists of an infrared light supply and is used for the emission infrared ray.Described infrared light supply also can adopt the infrared facility that is used for data transmission in the described portable terminal in addition, thereby can farthest utilize the existing hardware condition of portable terminal to realize antitheft function.
Described infrared proximity transducer 2 is for detection of the infrared ray of launching through the described infrared LED 1 of reflection, and described infrared ray sensor 2 also can adopt other infrared-sensitive device in addition.
Described loudspeaker 3 can use the loudspeaker in the described portable terminal, if do not have loudspeaker in the described portable terminal, then need in described portable terminal, introduce a loudspeaker, and described loudspeaker 3 preferably adopts the loudspeaker of large volume, thereby can obtain good warning effect.
Be set with an emission cycle T among the described MCU4, and control the unlatching of described infrared LED 1 or close according to this emission cycle T, and also control the unlatching of described loudspeaker 3 according to the testing result of described infrared proximity transducer 2 or close.
The principle of work of the theft preventing mobile terminal of the present embodiment is as follows:
After the user does not use portable terminal and it is taken in, for example mobile phone is put into bag or pocket is medium.
At first described MCU4 controls described infrared LED 1 emission infrared ray according to default emission cycle T, owing to being easy to reflection when infrared ray meets with obstruction thing, so when portable terminal placed other contents, described infrared ray was detected by described infrared proximity transducer 2 through the reflection of contents.
Then described MCU4 judges whether to receive infrared ray according to described infrared proximity transducer 2 testing results, for example when described infrared proximity transducer 2 detects infrared ray, produce a high level signal, produce a low level signal when not detecting infrared ray, described MCU4 is that high level or low level judge whether described infrared proximity transducer 2 receives infrared ray according to the level that described infrared proximity transducer 2 produces.
After this, when the described infrared proximity transducer 2 of MCU4 interpretation receives infrared ray, namely described infrared proximity transducer 2 produces a high level signal, and described MCU4 closes described loudspeaker 3.
When the described infrared proximity transducer 2 of MCU4 interpretation does not receive infrared ray, namely described infrared proximity transducer 2 produces a low level signal, and described MCU4 opens described loudspeaker 3, and described loudspeaker 3 sends chimes of doom.
Theft preventing mobile terminal described in the present embodiment is detected the improper movement of portable terminal by infrared induction technology, and for the user provides warning message, thereby effectively prevented the stolen of portable terminal.
The second embodiment:
The difference of the present embodiment and the first embodiment is:
As shown in Figure 2, also comprise a keyboard 5 in the present embodiment, described keyboard is used for user input data, for example, and password or password etc.And can be according to the requirements such as kind of input data, the input block of employing other types is realized the function of user input data.
And also be preset with among the MCU4 described in the present embodiment a password A and one input time Tinput, wherein said input time, Tinput inputted the time of the passwords such as password for the user, and described MCU4 detects the user and whether inputs data by described keyboard 5 in described input time Tinput.Whether described MCU4 also is used for more described password A identical with the data of user's input, thereby controls the unlatching of described infrared LED 1 and loudspeaker 3 or close.
The principle of work of the theft preventing mobile terminal of the present embodiment is as follows:
Whether at first described MCU4 detects the user by keyboard 5 input data in default input time Tinput, if do not detect the input data, whether then repeat again to detect the user by keyboard 5 input data.
If detect the input data, then described MCU4 compares the data of user's input with the password A that presets, if the data of described input are different from password A, whether then repeats again to detect the user by keyboard 5 input data, otherwise described MCU4 closes described loudspeaker 3 and infrared LED 1.
So contingent wrong report when having prevented that the user from initiatively making described portable terminal move.
Then described MCU4 controls described infrared LED 1 emission infrared ray according to default emission cycle T, and described infrared proximity transducer 2 detects the infrared ray that receives through reflection.
After this described MCU4 judges whether to receive infrared ray according to described infrared proximity transducer 2 testing results.
At last, receive infrared ray when MCU4 judges described infrared proximity transducer 2, described MCU4 closes described loudspeaker 3.
Do not receive infrared ray when MCU4 judges described infrared proximity transducer 2, described MCU4 opens described loudspeaker 3, and described loudspeaker 3 sends chimes of doom.
The theft preventing mobile terminal of this city embodiment is by adding the pattern of access customer identification, so that user self is so that portable terminal when moving, can be closed this infrared detection or warning, so can not report by mistake.
The 3rd embodiment:
The difference of the present embodiment and the first embodiment is:
Theft preventing mobile terminal in the present embodiment as shown in Figure 3, also comprises a reserve battery 6 and a power supply and power supply selection detecting unit 7.
Wherein said power supply detection and power supply selected cell 7 are for detection of whether Power supply is arranged in the described theft preventing mobile terminal.Described reserve battery 6 provides power supply for described theft preventing mobile terminal.Thereby can prevent that other people from removing the anti-theft feature of portable terminal by the mode of dismantling the power supplys such as battery.
Described reserve battery 6 can be fixedly installed on described theft preventing mobile terminal in addition, thereby can prevent that reserve battery 6 is disassembled, and removes in this way the anti-theft feature of portable terminal so prevent further other people.
No matter whether described portable terminal detects infrared ray in the present embodiment, namely no matter whether the anti-theft feature of described portable terminal is opened, described power supply detects and power supply selected cell 7 detects all the time whether Power supply is arranged in the described portable terminal, if testing result is not for there being Power supply, then control 6 pairs of described portable terminals of described reserve battery power supply is provided, provide power supply otherwise close 6 pairs of described portable terminals of reserve battery.
This shows that the present embodiment has effectively prevented portable terminal and do not waited the portable terminal that behavior caused that the problem of anti-theft feature can not be provided owing to having the battery of electricity or portable terminal to be taken down by the people, so improve the anti-theft capability of guarding against theft for mobile terminal function.
Although more than described the specific embodiment of the present invention, it will be understood by those of skill in the art that these only illustrate, protection scope of the present invention is limited by appended claims.Those skilled in the art can make various changes or modifications to these embodiments under the prerequisite that does not deviate from principle of the present invention and essence, but these changes and modification all fall into protection scope of the present invention.
