Step, the currency changing different outmoded degree repeats the first step, obtains the ink feature spectrum of different outmoded degree currency, set up the oil of currency
Ink characteristic spectrum data base；3rd step, obtains ink feature spectrum to be tested by currency to be tested by the first step, to be tested
Ink feature spectrum contrasts with the data in ink feature spectra database, and coupling is then genuine article coin, does not mates, and is false
Currency.
The further setting of the present invention is: described light group is infrared ray light group, and infrared ray is completely covered currency table
Face is irradiated penetrating, and currency opposite side is received by receptor, and infra-red intensity is converted into magnitude of voltage, ink feature light
Spectrum is converted into voltage data, during illumination, is voltage oscillogram ink feature spectral translation, checks currency in the 3rd step
Time, contrasted by voltage data.
The further setting of the present invention is: described light group is reflection light group, the first step, second step, anti-in the 3rd
Penetrating light perpendicular projection on currency surface, utilize the lines of currency surface printing to reflect, opposite direction arranges spectrum acquisition plate, instead
Penetrate light and be incident upon currency surface, have the partially reflective light of printing stricture of vagina first to reach spectrum acquisition plate, do not print the anti-of lines position
Penetrating light, to reach time of spectrum acquisition plate long, reflects light at spectrum acquisition plate for delay and carries out filtering or define different
Feature, forms the characteristic spectrum of ink lines on spectrum acquisition plate.
The further setting of the present invention is: connects sensillum opticum on spectrum acquisition plate, is carried out by the optical signal of preferential receipt
Signal converts and draws, and postpones the signal received, additionally draws, and with different signal characteristic set, forms the characteristic light of ink
Spectrum.
The further setting of the present invention is: described light group is arranged on mobile parts, is scanned currency
Gather signal.
Said method, coordinates the function of data conversion by photo effect, it is achieved that the purpose of the plane inspection currency true and false, logical
Cross such method, the consumptive material of cash inspecting machine can be substantially reduced, at utmost simplify the volume of paper money counter, improve the standard of currency examination
Really property, realizes because the making of counterfeit money is counterfeit various anti-false sign, but due to the restriction of printing technology, currency is most difficult to
Print exactly, no matter which kind of counterfeit money, printing cannot be imitated, and its essence of the method for the present invention is exactly a kind of inspection printing
The method of situation.
Detailed description of the invention
A kind of spectral signature molding banknote detection method, its method is as follows: the first step, is kept flat by currency, irradiates goods by light group
Coin surface, utilize light transmission or reflection obtain currency surface ink feature spectrum, utilize the method obtain currency front with
The characteristic spectrum of reverse side is as standard feature spectrum；Second step, the currency changing different outmoded degree repeats the first step, obtains different old
The ink feature spectrum of old degree currency, sets up the ink feature spectra database of currency；3rd step, passes through currency to be tested
The first step obtains ink feature spectrum to be tested, and ink feature spectrum to be tested enters with the data in ink feature spectra database
Row contrast, coupling is then genuine article coin, does not mate then for fake products coin.
The present invention by this banknote detection method, is achieved that long-range currency examination application when, and terminal currency examination, as long as doing
Data are uploaded, it is only necessary to a server, and data base is external, just can be greatly reduced the volume of cash inspecting machine, and carry
Convenient, this equipment current by overturning paper money counter industry, this method has fully been liberated the structure in paper money counter and has been limited, it is achieved flat
Face currency examination, because carrying out currency examination by the form of photo, current technology cannot realize, because currency security mark can not be realized
Plane replicate, and profit is in this way, can the characteristic of currency security be acquired, and reappears collection of illustrative plates, is depicted as plane
Waveform or feature image, thus realize long-range plane identification function.
The further setting of the present invention is: described light group is infrared ray light group, and infrared ray is completely covered currency table
Face is irradiated penetrating, and currency opposite side is received by receptor, and infra-red intensity is converted into magnitude of voltage, ink feature light
Spectrum is converted into voltage data, during illumination, is voltage oscillogram ink feature spectral translation, checks currency in the 3rd step
Time, contrasted by voltage data.
The present invention utilizes the mode of infrared penetration to carry out the conversion of spectral signal, can be depicted as oscillogram after conversion,
So can facilitate the identification of sequencing, the voltage signal after conversion, process and transmit the most more convenient, and this method is using
When, terminal has only to a light group just can complete inspection.
The further setting of the present invention is: described light group is reflection light group, the first step, second step, anti-in the 3rd
Penetrating light perpendicular projection on currency surface, utilize the lines of currency surface printing to reflect, opposite direction arranges spectrum acquisition plate, instead
Penetrate light and be incident upon currency surface, have the partially reflective light of printing stricture of vagina first to reach spectrum acquisition plate, do not print the anti-of lines position
Penetrating light, to reach time of spectrum acquisition plate long, reflects light at spectrum acquisition plate for delay and carries out filtering or define different
Feature, forms the characteristic spectrum of ink lines on spectrum acquisition plate.
The present invention utilizes spectrum acquisition plate, false proof data through image, it is achieved that planarization currency examination, can make whole goods
Coin reflects with the form of characteristic image, and more comprehensively, the counterfeit money of splicing can catch currency examination, and currency examination accuracy rate is the highest.
The further setting of the present invention is: connects sensillum opticum on spectrum acquisition plate, is carried out by the optical signal of preferential receipt
Signal converts and draws, and postpones the signal received, additionally draws, and with different signal characteristic set, forms the characteristic light of ink
Spectrum.
