Abstract

The utility model relates to a theft-proof purse which belongs to the field of the radio technology and digital circuits. Touch elements and an alarm are arranged on a purse body. The alarm is composed of a radio personal identification receiver 2 and an alarm element. The utility model is also provided with a radio personal identification signal transmitter 6 which is separated from the purse body and can be worn on the owners' wrists or be clamped on the cuff. The metallic or nonmetallic electric conduction materials are fixed on both sides of the purse body, which forms the touch elements 3 and 4. When is used, the utility model is convenient as common purses. So long as other people touch the purse, the purse alarms to prevent the property of owners from loss.

Description

The intelligent anti-theft wallet

The utility model relates to a kind of antitheft wallet, belongs to radiotelegraphy and digital circuit field.

Prior art provides a kind of improved antitheft case and bag (to see Chinese patent 97227018.3; Notification number CN2299519Y), be characterized in being provided with on inclusion and protect curtain, with protecting the method whether curtain covers the touch element of wrapping, distinguishing the user is owner or robber, thereby whether decision reports to the police.Open case and bag when owner uses, will protect curtain earlier and put up the touch element of wrapping, stretch out one's hand and get thing, alarm just can not reported to the police; And the robber does not know to protect the effect of curtain, open case and bag after, directly stretch out one's hand and pick pockets, will touch touch element, cause alarm equipment alarm.Above-mentioned technology has the following disadvantages: inconvenience when 1, owner uses, all to put up on touch element (to avoid wrong report) when using protecting curtain at every turn, and will protect curtain after using up again and put up and open (otherwise alarm is with inoperative).2, this technical products listing in a single day, the robber may also can learn how to use to protect curtain very soon, and alarm is not reported to the police when it is committed a crime.3, this technology is applied on the little wallet of volume, be difficult for to realize antitheft (because this technical products only could be reported to the police when bag is got thing opening, the robber may just open wallet away from the crime scene).

For overcoming the prior art deficiency, the purpose of this utility model provides a kind of easy to use, can discern owner and robber's antitheft wallet automatically, do not report to the police when owner uses, and other people touches just warning of wallet.

The purpose of this utility model is to realize like this, a kind of antitheft wallet, inclusion is provided with touch element and alarm, alarm is made up of radio identification receiver 2 and alarm element, also is furnished with radio identification sender unit 6 simultaneously, it separates with inclusion, can be worn over owner's wrist or is stuck on the cuff;

Touch element

3,4 is fixed on the inclusion both sides, links to each other with the signal ground end with the touch signal input end of radio identification signal receiver 2 respectively.When the people touches the inclusion both sides simultaneously, radio identification signal receiver 2 will be opened, and at first receive radio identification signal, and whether decision reports to the police again.If owner touches inclusion, receiver 2 will receive the correct signal of password that radio identification sender unit 6 sends, and just can not report to the police; And other people touch inclusion, and receiver 2 will can not received correct code signal, and alarm will be reported to the police.

Convenient when the utility model uses as common wallet, and other people are in case touch will be reported to the police, and stop robber's crime in time, ensure that owner's property is not suffered a loss.

Fig. 1 is wallet and radio ID transmitter outside drawing and uses synoptic diagram.

Fig. 2 is wallet and radio identification sender unit electrical schematic diagram.

Fig. 3 is wallet and radio identification signal receiver electrical schematic diagram.

Below in conjunction with accompanying drawing the utility model is described further: referring to Fig. 1,1 is inclusion, 2 is radio identification signal receiver, it is fixed in the inclusion, by single-chip microcomputer U (see figure 3), radio signal radiating circuit 9, radio signal receiving circuit 8, alarm element 5,

touch element

3,4 is formed; The I/O mouth of single-chip microcomputer U links to each other with one of an end of the output terminal of the input end of radio signal radiating circuit 9, radio signal receiving circuit 8, alarm element 5,

touch element

3,4 respectively; Another touch element connects the signal ground end.Touch element can be that the nonmetal thing of metal object or conduction is separately fixed at the inclusion both sides; 6 is wireless identity identification signal transmitter, is made up of single-chip microcomputer U, (referring to Fig. 2) radio signal radiating circuit 9, radio signal receiving circuit 8, light emitting diode LR, keyswitch S; The I/O mouth of single-chip microcomputer U links to each other with the input end of radio signal radiating circuit 9, the output terminal of radio signal receiving circuit 8, the negative electrode of light emitting diode LR, the end of keyswitch S respectively.7 is watchband, on the wireless identity identification signal transmitter 6 clamp is arranged, and may be stuck on the watchband.Single-chip microcomputer U adopts the PIC12C508 or the PIC12C509 of U.S. MICROCHIP company; Radio signal receiving circuit 8 is made of triode detection level and low frequency signal amplifier stage; Radio signal radiating circuit 9 is a pulse amplifying circuit, directly amplifies the pulse-modulated carrier signal that sends from single-chip microcomputer U.The course of work of the present utility model is as follows, no matter be radio identification sender unit 6, all be in sleep state (power consumption is extremely low) when still the single-chip microcomputer U in the radio identification signal receiver 2 is flat, when the people touches the inclusion both sides, the single-chip microcomputer U of receiver 2 is waken up, send interrogating signal thereupon, if radio identification this moment sender unit 6 is in the signal range of receiving (owner uses wallet), single-chip microcomputer U wherein will be waken up by interrogating signal, send the wireless identity identification signal thereupon, after receiver 2 is received the wireless identity identification signal,, just no longer report to the police if password is correct through confirming; If password not to or can not receive the wireless identity identification signal at all, just report to the police by I/O password hummer 5.
