Abstract

This invention relates to anti-theft and losing system with electrical card and combination with cell phone, which comprises the emission coding signal electrical anti-theft card one and cell phone of to receive the code signal and to identify alarm signals. The invention has communication function and is as one anti-theft part to avoid the thefts and loses.

Description

The anti-theft and anti-loss system of electronic anti-theft card and mobile phone combination

Technical field

The present invention relates to anti-theft and anti-loss system by electronic anti-theft card and mobile phone combination.

Background technology

Though the cell-phone function of prior art is many, can not effectively play the effect of antitheft anti-loss.When people went out, valuables such as mobile phone, wallet, briefcase thing stolen, that lose happened occasionally, and needed badly with technological means to be prevented.

Summary of the invention

The technical problem to be solved in the present invention is, defective at the prior art existence, the anti-theft and anti-loss system of a kind of electronic anti-theft card and mobile phone combination is provided, electronic anti-theft card and mobile phone are placed apart, the two can make mobile phone send alarm signal when being separated into certain distance, thereby avoids mobile phone or relative article stolen or lose.

Technical solution of the present invention is, but the anti-theft and anti-loss system of described electronic anti-theft card and mobile phone combination by the electronic anti-theft card of transmit coded signals and receive described code signal and after discerning the mobile phone of may command alarm signal form.

Below make and further specifying.

Referring to Fig. 1, but the present invention by the electronic anti-theft card 1 of transmit coded signals and receive described coding and after discerning the mobile phone 2 of may command alarm signal form.

Described electronic anti-theft card 1 can be various shape and structure.Described mobile phone 2 comprises the various mobile phones (for example " GSM mobile handset is repaired, and is proficient in from crossing the threshold to ", National Defense Industry Press publishes January calendar year 2001, the Liu Wuping chief editor) of prior art.

Described electronic anti-theft card 1 is made up of governor circuit 3 and coding circuit 4, transmitter module 5, and the signal output part of described governor circuit 3 is connected with the input of coding circuit 4 and the output of this coding circuit 4 is connected with the signal input of transmitter module 5.

Described mobile phone 2 carries out software upgrading by existing mobile phone and forms, and makes it to possess reception by the coded electronic signal of electronic anti-theft card 1 emission and carry out the function of respective handling.

Operation principle of the present invention and using method be, during actual the use, earlier the mains switch of electronic anti-theft card 1 is opened and pack into wallet or other valuables of carrying in, on one's body mobile phone 2 places in addition.When electronic anti-theft card 1 enters operating state, mobile phone also is set at anti-theft state, this moment, mobile phone 2 embedded anti-theft program started, receive continuously the code signal of sending by electronic anti-theft card 1 and discern, this signal transmission power can be set transmitting range in 2 meters after debugging, this distance is a safe range, in case electronic anti-theft card 1 leaves mobile phone 2 when reaching more than 2 meters, alarm signal (reporting to the police as audio communication) prompting machine master can be taken place when mobile phone 2 can't receive this signal, and reporting to the police when the distance of electronic anti-theft card 1 and mobile phone 2 comes back in the safe range automatically terminates; When the anti-theft feature of mobile phone starts, if detect less than the code signal that sends by electronic anti-theft card 1, just mobile phone 2 can be in alarm condition and lock all functions, mobile phone 2 cisco unity malfunctions always; Two kinds of releasing ways are arranged this moment: the firstth, directly electronic anti-theft card 1 is moved within the safe distance scope, another kind may be when electronic anti-theft card 2 can't be fetched, then the security password that directly input is correct is removed the anti-theft state of mobile phone 2, and mobile phone 2 can normally use.

As known from the above, the present invention is the anti-theft and anti-loss system of a kind of electronic anti-theft card and mobile phone combination, and the function of its existing communication tool is again antitheft, an anti-utensil of losing, and can effectively avoid mobile phone or be placed with the article of electronic anti-theft card stolen or lose.Easy to use, the dependable performance of product can be described as burglar's jinx, will be to the generation positive role that maintains public order, and social benefit is huge and far-reaching.
