Description
Technical field
The invention belongs to commodity counterfeit prevention and detection technique field, Kaifeng, be specially electronic anti-fogery label resistance-type commodity Kaifeng circuit and Kaifeng detection method.
Background technology
At present, false proof for commodity, a kind of method is to adopt to use special process in commodity packaging, another kind method is to use the trade mark of complex pattern, advanced printing process, and also having a kind of method is that the special marking is set on commodity, all is to rely on people's sense organ to carry out truth identification to these method for anti-counterfeit, the layman is difficult to distinguish, and cracked by the fake producer easily, in case grasped by other people, antifalse effect will rapidly disappear.
Summary of the invention
The objective of the invention is to: provide a kind of electronic anti-fogery label with resistance-type commodity Kaifeng circuit and Kaifeng detection method, be intended to solve the problems referred to above that prior art exists.
The object of the present invention is achieved like this:
The electronic anti-fogery label with resistance-type commodity Kaifeng circuit by A printed resistor 1, B printed resistor 2, read resistance unit 3, numerical evaluation unit 4, Kaifeng bar 5 is formed.Kaifeng bar 5 is affixed on the circuit substrate 6, and A printed resistor 1 is printed on Kaifeng bar 5 and the circuit substrate 6, and B printed resistor 2 is printed on the circuit substrate 6.
During the initialization of electronic anti-fogery label, by reading to calculate A printed resistor 1 ratio, storage ratio in the resistance value input value computing unit 4 that resistance unit 3 reads A printed resistor 1, B printed resistor 2 than last B printed resistor 2; Tear during Kaifeng Kaifeng bar 5, therefore the resistance of A printed resistor 1 will change, again by reading in the resistance value input value computing unit 4 that resistance unit 3 reads Kaifeng back A printed resistor 1, B printed resistor 2, calculate A printed resistor 1 ratio than last B printed resistor 2, the odds ratio of ratio that records behind the Kaifeng and initialization storage, phase missionary society is very big, illustrates that commodity are fake and forged or have been broken a seal, and reach the purpose that detects commodity true and false and whether break a seal.
Therefore good effect of the present invention shows: low, the easy production of P.e.c. cost, resistance can be regulated arbitrarily during production, has to duplicate advantages such as reduction difficulty height, randomness are strong.
Description of drawings
Fig. 1 is the structural drawing of the electronic anti-fogery label that provides of the embodiment of the invention with resistance-type commodity Kaifeng circuit and Kaifeng detection method;
Wherein, 1---A printed resistor, 2---B printed resistor, 3------numerical evaluation unit, 5---Kaifeng bar, 6---circuit substrate of reading resistance unit, 4.
Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated, for convenience of explanation, only show the part relevant with the embodiment of the invention, these parts can be the unit of software, hardware or software and hardware combining.
The electronic anti-fogery label with resistance-type commodity Kaifeng circuit by A printed resistor 1, B printed resistor 2, read resistance unit 3, numerical evaluation unit 4, Kaifeng bar 5 is formed.During the initialization of electronic anti-fogery label, by reading to calculate A printed resistor 1 ratio, storage ratio in the resistance value input value computing unit 4 that resistance unit 3 reads A printed resistor 1, B printed resistor 2 than last B printed resistor 2; Tear during Kaifeng Kaifeng bar 5, therefore the resistance of A printed resistor 1 will change, again by reading in the resistance value input value computing unit 4 that resistance unit 3 reads Kaifeng back A printed resistor 1, B printed resistor 2, calculate A printed resistor 1 ratio than last B printed resistor 2, the odds ratio that the ratio that records behind the Kaifeng and initialization are stored, if differ greatly, illustrate that commodity are fake and forged or have been broken a seal, and reach the purpose that detects commodity true and false and whether break a seal.
For example before the Kaifeng, A printed resistor 1 is 30000 ohm, B printed resistor 2 is 10000 ohm, reads during initialization to calculate A printed resistor 1 ratio X than last B printed resistor 2 in the resistance value input value computing unit 4 that resistance unit 3 reads A printed resistor 1, B printed resistor 2:
Computing formula: X=(A ÷ B) * 1000
X＝(30000÷10000)×1000＝3000
When extraneous occurrence temperature changes, or explained hereafter error, make resistance value change, because A printed resistor 1 is identical with production technology with B printed resistor 2 materials, the changes in resistance ratio also is identical, if resistance change rate is 5%, initialization A printed resistor value A=30000 * (1+5%)=31500 then;
B printed resistor value
B＝10000×(1+5％)＝10500；
Calculate the output ratio X ':
X’＝(31500÷10500)×1000＝3000
Can see that X and X ' ratio equate that ratio will can not be subjected to the influence of temperature variation or fabrication error.
The Kaifeng bar 5 of tearing during Kaifeng, the resistance of A printed resistor 1 will produce great changes, and the A printed resistor 1 that calculates changes with corresponding than the ratio of last B printed resistor 2, with the preceding ratio that breaks a seal bigger difference is arranged.
