The module is characterized in that the module mainly comprises a sensor shell(1) spanning a coin outlet channel and opposite inductances(L1 and L2) which are arranged in the sensor shell(1), wherein a coin channel(2) is arranged between the inductances(L1 and L2); a photoelectric coupling tube(3) is also arranged on the shell(1) and at the entrance of the coin channel(2); an electromagnet(4) for detecting the coin is arranged on the shell(1) and at the exit of the coin channel(2); and the input end of the inductance(L1) is connected with the output of a frequency oscillator, and the output of the inductance(L2) is connected with a signal receiving processing circuit. The module has the advantages of reliable operation, simple structure and convenient manufacturing and mounting.
Description
Technical field
The utility model relates to a kind of bill counter, especially a kind of coin point coin, tests the false proof module that coin is used, the false proof module of specifically a kind of coin-freed apparatus.
Background technology
At present, because coin is the metal coin, the anti-counterfeiting information of itself is limited, except carry out from material false proof, remaining false proof means be difficult to adopt, because the chemical analysis of hard is difficult to express-analysis, therefore, the anti-counterfeiting detection of coin is an insoluble difficult problem always, so that Jia coin is difficult to test out by testing the coin machine in the market, and existing coin counting machine has also only played the effect of coin counter.In addition, existing coin-freed apparatus also must be tested the coin machine accordingly at the coin design of different denominations, and its versatility is relatively poor.
Summary of the invention
The purpose of this utility model is to test the coin machine at existing coin not possess anti-counterfeiting performance and can not accurately differentiate the problem that the face amount number of categories is tested, and designs the false proof knowledge coin of a kind of coin-freed apparatus based on vortex principle module.
The technical solution of the utility model is:
The false proof knowledge coin of a kind of coin-freed apparatus module, it is characterized in that it mainly goes out the sensor outer housing 1 on the coin passage and be installed in opposed inductance L 1 in the sensor outer housing 1 by straddling coin, L2, inductance L 1, be provided with coin passage 2 between the L2, on housing 1, the porch of coin passage 2 also is equipped with photocoupler 3, on housing 1, the exit of coin passage 2 also is equipped with beats the electromagnet 4 that coin is used, the input end of inductance L 1 links to each other with the output of frequency oscillator, and the output of inductance L 2 links to each other with the signal receiving processing circuit.
The beneficial effects of the utility model:
The utility model utilizes vortex principle both to solve the problem of the partition test of coin, the coin of different area is entered respectively in the different collection coin devices, simultaneously can report to the police automatically and hit down, and whole modular structure be simple, makes easy for installation the counterfeit money that passes through.

Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
The false proof knowledge coin of a kind of coin-freed apparatus module, it mainly (can be formed by plastic injection-moulded by straddling the sensor outer housing 1 that coin goes out on the coin passage,) and be installed in opposed inductance L 1 in the sensor outer housing 1, L2, inductance L 1, be provided with coin passage 2 between the L2, as shown in Figure 1, on housing 1, the porch of coin passage 2 also is equipped with photocoupler 3, and on housing 1, the exit of coin passage 2 also is equipped with beats the electromagnet 4 that coin is used, as shown in Figure 2, also be provided with on housing 1 and be used for the screw mounting hole 5 that is fixedly linked with coin passage, the input end of inductance L 1 links to each other with the output of frequency oscillator, and the output of inductance L 2 links to each other with the signal receiving processing circuit.
Fig. 4 is the theory diagram of the signal Processing of false proof knowledge coin module of the present utility model, and wherein each corresponding circuit can adopt circuit ripe on the textbook or corresponding integrated circuit to be realized that Fig. 5 is a comparatively typical electric principle schematic.
Principle of work of the present utility model is:
Be added to the two ends of inductance L 1 by the multiple-frequency signal V of frequency oscillator generation, this moment as two inductance L 1, when not having tested coin between the L2, the magnetic force of L1 will directly run through L2, thereby produce sympathetic electromotive force E at the two ends of L2, if there is coin 6 to enter L1, between the L2, then photoelectrical coupler 3 is sensed and is triggered frequency oscillator immediately and starts working (as shown in Figure 3), the magnetic force line cutting coin, and in coin, produce eddy current i, this eddy current loss the part magnetic field energy, make the magnetic line of force that arrives L2 reduce, cause the decline of sympathetic electromotive force E, the thickness of coin is thick more or effectively to enter the area in magnetic field big more, the loss of eddy current is just big more, and E is just more little, because the thickness of coin different denominations, the area difference, can declare the face amount that coin in view of the above, and by electromagnet the coin of large tracts of land or small size be pushed away coin passage and enter in the corresponding coin collector.The size of eddy current i in the coin not only depends on the thickness and the area of coin, and it is relevant with the resistivity of coin, and resistivity is relevant with the chemical constitution and the physical state of metal material, because the resistivity of same face amount genuine note is definite value, between the coin of same face amount was by inductance L 1, L2, eddy current and genuine note that counterfeit money produced were inconsistent, and can determine the coin that is passed through in view of the above is counterfeit money, can trigger the electromagnet action, the counterfeit money that will pass through is hit down.
The utility model does not relate to the part prior art that maybe can adopt all same as the prior art to be realized.
