Abstract
The utility model discloses light becomes password wallet theftproof card comprises light change testing section, decoding part, warning stereo set part and code key. The miniature electronic components are used to make thin card by surface mounting technology. The card can be put into a wallet, the password key is pasted on the outer side of the wallet, and the photodiode is exposed on any side edge of the wallet to sense the change of light. When in use, the alarm password is randomly put into the bag according to a non-forbidden alarm password. When the bag is taken out, the alarm sound is given out because the light outside the bag is stronger than that in the bag because other people do not know the password.
Description
It is the technical field that belongs to antitheft wallet or antitheft certificate folder that the utility model-light becomes the antitheft card of password wallet, and it changes with utilizing light, and password identification causes that the device of electronic warning system warning is relevant.
According to the knowledge of the applicant in invention of the present utility model with before the applying date, occurred three kinds of antitheft wallets, but all existed some unreasonable unpractical shortcoming.A kind of is the antitheft wallet of magnetic control, its shortcoming is to need magnet and wallet to empocket together, wallet just sends warning after leaving the magnet certain distance, carries very inconveniently like this, and causes wrong report owing to the people can make wallet and magnet produce to separate at the volley.Another kind is a pressure type electronic warning and anti-theft wallet, it causes warning by being placed in the adhesive that is stressed of two sheet metals on inboard two relative edges of wallet, its shortcoming is that wallet is squeezed and easily produces wrong report, and its anti-theft is also relatively poor, the thief can not make the two metal sheets adhesive and take out wallet, as severs pocket and take out wallet.Another is the light-controlled antitheft wallet, and this wallet is subjected to illumination and just sends warning, and its shortcoming is to cover light source after the thief takes out rapidly chimes of doom is disappeared, and can not continue to report to the police, and it is stronger to the dependence of light intensity.One of these three kinds of antitheft wallets big shortcoming can not be distinguished owner and other people exactly in addition, all might produce warning when owner takes out wallet, and its practicality is subjected to very big influence.
The purpose of this utility model is: solved the antitheft wallet of magnetic control and carried problem inconvenient and that easily report by mistake, easy wrong report of pressure type electronic warning and anti-theft wallet and anti-theft are poor, and the problem that the light-controlled antitheft wallet too relies on light intensity.And having solved these several antitheft wallets is regardless of owner and other people and produces the problem of wrong report.It provides under very weak light, if see through some light and can distinguish owner or other people and produce warning.
Fundamental purpose of the present utility model realizes by following technology contents: its major technique partly is on the antitheft card, antitheft card is by light change-detection part (2), decoding part (3), alarm sound part (4) and cryptographic key (5) are formed, and light change-detection part (2) is by photodiode D

Light change-detection part (2), decoding part (3), the electronic devices and components of alarm sound part (4) all adopt micro element, and adopt surface mounting technology to be welded on the printed circuit board (PCB).In addition, battery (16), battery case (14), micro power K switch
0(15), wire socket (18) also all is connected with printed circuit board (PCB) and becomes one laminar by plastic package.This thin card is placed and be fixed in the internal layer of wallet (7) photodiode D
1Be exposed at the lateral margin of wallet (7), and cryptographic key (5) sticks on the outside surface of wallet (7), the lead on it (6) inserts in the socket of card.
When using wallet, the closed micro power K switch of elder generation
0(15), make circuit working, before wallet is put into pocket, arbitrarily import one group of non-alarm cipher of forbidding earlier, and put into pocket simultaneously, this moment, card was in alarm condition.If want to take out wallet in person, should first input inhibit alarm cipher, and then take out, then can not report to the police.If do not forbid alarm cipher and do not input password or input by mistake, because extraneous light strong than in the bag, detect the variation of this light when then taking out by light change-detection part (2), excited thus and reported to the police and produce chimes of doom.This chimes of doom will be constantly up to disconnecting the micro power K switch
0(15) or import correct forbidding till the alarm cipher.

3CLR end be 0 (low level), the PR end still is 1 (high level), IC
3Output terminal Q be 0, it makes trigger IC
2D and CLR end be 0, IC then
2Q end be 0, it is forbidden by IC
7The alarm sound part of forming (4) produces vibration and sends chimes of doom.And when press arbitrary group non-when forbidding the alarm cipher key, IC
3CLR end still remain 1, and the PR end is 0, then its Q end is 1, makes IC
2D and CLR end be 1, IC
2Q end still keep initial value constant, and when light changes, be input to IC by the high level pulse of light change-detection part (2) generation
2CLK end, it impels trigger IC2 that saltus step, i.e. IC take place
2The level of Q end consistent with the D end, be 1 this moment, it makes the alarm sound part (4) of back produce to vibrate and the generation chimes of doom.
Alarm sound part (4), its function are (to be IC after decoding part (3) is sent alerting signal
2Q end become at 1 o'clock), produce oscillator signal drive pressure electroceramics buz HTD (9) and send chimes of doom.It is by time base circuit IC

3Battery case (14) is the drawer sample, when changing battery (16), as long as extract battery case (14) out, changes new battery and advances battery case to get final product.
By layout shown in Figure 4, welded circuit, hummer (9) is welded on the circuit board, the positive plate of battery is contained in battery case (14) lining, carry out overall package by structure shown in Figure 4 with plastics, the intact structure of overall package as shown in Figure 5, the audible segment of hummer (9) is not enclosed in the plastics, so that sounding is loud and clear.An ommatidium is made a call in outside surface somewhere at wallet during use, the lead (6) that is connected on the cryptographic key (5) is passed ommatidium, and cryptographic key (5) is sticked on the ommatidium place of wallet with multi-purpose adhesive, as shown in Figure 6, the termination of lead (6) is inserted in the socket (18) of card (1), the power switch K of antitheft card (1)
0(15) closed and be placed in the internal layer of wallet (7), as shown in Figure 6, photodiode (8) is exposed at lateral margin.Wallet (7) is put into bag, and press the non-alarm cipher of forbidding and get final product.As long as other people not by to or not by forbidding the alarm cipher key, from bag, take out wallet, will send chimes of doom.This chimes of doom will be constantly up to disconnecting the micro power K switch
0(15) or import correct forbidding till the alarm cipher.
The explanation of the specific embodiment of scheme two: its decoding part (3) adopts circuit shown in the accompanying drawing 3, and remainder is identical with scheme one.In accompanying drawing 3, cryptographic key (20), (21), (22) are through resistance R
6, R
7, R
8Directly link trigger IC
3CLR and PR end, and removed three or eight code translator IC
4With four inputs and door IC

6, its password is only determined by some singly-bounds like this, if promptly K
1Key is linked trigger IC
3CLR end, K
2And K
3Key is linked IC
3PR end, then press K
1Key is forbids alarm cipher, presses K
2Or K
3Key then is the non-alarm cipher of forbidding.Equally, K
2Or K
3One of key also can be received IC
3CLR end, all the other keys are linked IC
3PR end.The characteristics of this circuit are simple, but password is few, has only three.
The utility model compared with prior art, the advantage that has is: as long as just see a little light Can send chimes of doom, anti-theft is strong, and is highly sensitive, can distinguish again simultaneously owner and other people, can not Produce wrong report, owing to adopt surface mounting technology, product can be done very thinly, is convenient to be placed on wallet Or in the certificate folder, do not take very big space, install also very convenient.
