Abstract
The invention discloses a kind of magnetic code anti-false method for commodity and device thereof, it is the magnetic recording material of packing in the external packing of commodity or bottle cap earlier, discern with recognizer again during use, magnetic recording material is made up of macromolecular material and magnetic, recognizer is made up of some groups of Hall integrated components, charactron, power supply etc., and it is simple, rapid that the present invention has recognition methods, strong security, be difficult for advantages such as counterfeit, be particularly suitable for merchandise sales unit and use.
Description
The invention belongs to a kind of anti-counterfeiting technology of commodity, particularly a kind of the coding with magnetic carried out false proof technology.
In existing anti-counterfeiting technology, common have bar code and a laser hologram image, though these methods have very high antifalsification, but for the consumer or the merchant that stocks up, can not can both remember its bar code or image to extensive stock, so in real life, these methods still have significant limitation.
The objective of the invention is to: provide a kind of and carry out false proof method and device thereof with the magnetic coding techniques so as rapidly, accurately, reliably, the true and false of recognition value easily.
The present invention is achieved in that magnetic code anti-false method for commodity, and it is the magnetic recording material (1) of packing in the external packing of commodity or bottle cap earlier, uses recognizer (2) to discern during use again; Make device in this way, it is made up of magnetic recording material (1) and recognizer (2), magnetic recording material (1) is made up of macromolecular material and magnetic, recognizer (2) is by some groups of Hall integrated components (3), charactron (4), power supply (5), switch (6) are formed, the positive pole of power supply (5) connects switch (6), the positive pole of Hall integrated component (3) and the public pole of charactron (4), the negative pole of power supply (5) connects the negative pole of Hall integrated component (3), the negative pole of the output termination charactron (4) of Hall integrated component (3).
Compared with prior art, it is simple, rapidly that the present invention has recognition methods, and security performance is strong, be difficult for advantages such as counterfeit, magnetic recording material has the characteristics of long term storage information, recognizer is simple in structure, easy to manufacture, and antijamming capability is strong, is particularly suitable for merchandise sales unit and uses.
Accompanying drawing 1 is that principle assumption diagram, the accompanying drawing 2 of recognizer of the present invention is Hall integrated component figure of the present invention, and accompanying drawing 3 is the synoptic diagram of magnetic recording material of the present invention in commodity (bottle cap), and accompanying drawing 4 is a circuit diagram of the present invention.
Embodiments of the invention: use dry cell as power supply (5), pack in the recognizer (2), the public pole of the anodal tandem tap (6) of power supply (5), the positive pole of Hall integrated component (3) and charactron (4), its negative pole connects the negative pole of Hall integrated component (3), the negative pole of the output termination charactron (4) of Hall integrated component (3).
In bottle cap (7), be pressed into magnetic recording material (1), when detecting commodity, be buckled in bottle cap (7) with identification its (2) and go up rotation, magnetic signal on magnetic recording material (1) and Hall integrated component (3) S are in the face of seasonable, its negative pole and output terminal conducting, charactron shows, reaches the purpose of distinguishing true from false.
Reach the purpose of the multiple different commodity of identification, only need in this circuit, to seal in a plurality of Hall integrated components, carry out certain combination for certain commodity, the corresponding this Hall integrated component of this kind magnetic recording signal shows specific number on charactron, just the true and false of the very easy recognition value of energy.
Claims (2)
1, a kind of magnetic code anti-false method for commodity is characterized in that: it be in the external packing of commodity or bottle cap, pack into earlier magnetic recording material (1), use recognizer (2) to discern again when using.
2, a kind of device that uses said method, it is made up of magnetic recording material (1) and recognizer (2), it is characterized in that: magnetic recording material (1) is made up of macromolecular material and magnetic, recognizer (2) is by some groups of Hall integrated components (3), charactron (4), power supply (5), switch (6) is formed, the positive pole of power supply (5) connects switch (6), the public pole of the positive pole of Hall integrated component (3) and charactron (4), the negative pole of power supply (5) connects the negative pole of Hall integrated component (3), the negative pole of the output termination charactron (4) of Hall integrated component (3).
