Foregoing circuit, power supply all are arranged on the place, inboard that is fixed on wallet 1 in the control box, hand switch K ₁, K ₂, K ₃, K ₄With wallet 1 flush, inlay the magnet with wallet 1 corresponding coupling in the annex 2 that soft material is made, annex 2 is fixed on the pocket inboard and locates.

Advantage of the present utility model mainly contains:

1, the anti-theft device structure of this wallet is simpler, makes easily, and cost is lower;

2, the anti-theft device combination pin of this wallet is many, and strong security is not easy brokenly sign indicating number, the security reliability height.

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1 is the magnetic control system schematic diagram of the antitheft wallet of magnetic control electronic cipher;

Fig. 2 is wallet and annex magnet the two poles of the earth coupling schematic diagram of the antitheft wallet of magnetic control electronic cipher.

As shown in the figure, the K of magnetic gauge tap I ₅, K ₆, K ₇With hand switch K ₁, K ₂, K ₃, K ₄Straight-through 6V power supply.

When oneself taking wallet, at first press hand control switch K ₁Make its closure, voltage is added in BG simultaneously ₁Colelctor electrode and base stage are at delay circuit R ₁C ₁In the delay time of design, base voltage is lower than 0.7V, BG ₁Not conducting, colelctor electrode output HIGH voltage

6V inserts IC

₁1 pin with door is added on BG simultaneously ₂The base stage high potential; Then in delay time, press K ₂Make its closure, BG ₂Conducting emitter-base bandgap grading and output are connected to IC ₁Input 2 pin with door are added on BG simultaneously ₃Base stage because IC ₁Be high potential, IC with 1 pin, 2 pin of door ₃3 pin of NAND gate promptly with go out corresponding high potential and be added on 5 pin; Down press K again ₃Make its closure, BG ₃Conducting emitter-base bandgap grading output high potential is connected to IC ₁Input 6 pin with door are added on BG simultaneously ₄Base stage because IC ₁Being high potential with 5 pin, 6 pin of door, is high potential with going out its 4 pin just, through IC ₁Transport to IC with output 4 pin of door ₃Input 2 pin of NAND gate; At last press hand switch K to give fixed number of times ₄, BG ₄The pulse signal of emitter-base bandgap grading output respective counts be added on IC ₂Input 14 pin of decade counter integrated package are by back by tightly not loosing one's grip IC to giving fixed number ₂Promptly export a high potential and be added on IC with output 13 pin of door ₃Input 8 pin place, the IC before this of NAND gate ₃Input 2 pin of NAND gate are added with from IC ₁With the high potential of door 4 pin input, when taking out wallet, each K switch of magnetic gauge tap group I ₅, K ₆, K ₇Lose the magnet suction of annex 2, auto-closing under spring action, high potential promptly are added on IC ₃ NAND gate input 1 pin, IC ₃Three input 1 pin, 2 pin, 8 pin of NAND gate are high potential, IC ₃ NAND gate output 9 pin are zero potential, and this zero potential is with BG ₅Base stage is clamped at below the 0.7V, so BG ₅, BG ₆, IC ₄Do not work Deng all, thereby can not report to the police.

When others' wallet 1 of taking is not pressed hand control switch K ₁, K ₂, K ₃, K ₄The time, wallet 1 leaves lay down location 3cm, and the magnetic gauge tap on it just loses the magnet suction of annex 2, the K switch of magnetic gauge tap I ₅, K ₆, K ₇Promptly under spring action, swing on one side and closure is or the door state, only needing a closing point to connect be exportable high level, the electric current IC that goes directly ₃ Input 1 pin of NAND gate, because of its in addition two inputs, 2 pin and 8 pin all do not have input, so its input 9 pin no-output still, electric current is through delay circuit R ₁₆C ₂After the time-delay in 0.01 second, arrive BG ₅Base stage, its potential rise to more than the 0.7V with BG ₅The emitter-base bandgap grading conducting is transported to IC with signal ₄Input SEL ₁, work as IC ₄Input terminal voltage rise to 1.5V when above, its output OUT promptly has output and makes its transistor BG ₆Enough base voltages are arranged and conducting, loudspeaker B promptly sends the siren alarm signal.

If misplay password, do not press each hand control switch in order, or do not decide number of times and press hand switch K by giving ₄, all press hand control switch K with above-mentioned showing ₁, K ₂, K ₃, K ₄The same, also make loudspeaker B send alarm signal.

If when surpassing the design time of time-delay because of slow movement, delay circuit R ₁C ₁Will full charge and make BG ₁Conducting, BG ₁Colelctor electrode is reduced to electronegative potential by high potential, simultaneously BG ₂, BG ₃, BG ₄Base stage is electronegative potential, even if at this moment beat password is made K again ₂, K ₃, K ₄Closure, BG ₂, BG ₃, BG ₄Also no-output, and make loudspeaker B send alarm signal.

Element of the present utility model, IC ₁Adopt and door integrated package CC4081, IC ₂Adopt decade counter CC4017, IC ₃Adopt NAND gate integrated package CC4023, IC ₄Adopt warning integrated package KD9561 or adopt voice integrated package TM801, BG ₁, BG ₂, BG ₃, BG ₄, BG ₅All adopt 3DK ₂Transistor, BG ₆Adopt 3DG ₆Transistor.

This circuit can be designed to large scale integrated circuit, comprises all transistors and integrated circuit.
