Wherein, the other end of interface shown in Figure 13 connects CPU, and the model of CPU can be selected according to actual needs.
The principle of work of the compound false-identifying device that the utility model provides is as follows: when Renminbi by going into after the paper money mouth puts into, arrive position transmissive tube 15 places on the luminous plaque, the light that position transmissive tube 15 is sent is blocked by Renminbi, light intensity weakens after seeing through Renminbi, position receiving tube 2 on the dash receiver receives after the weak variable signal of light intensity, convert thereof into electric signal, electric signal is through amplifying, shaping is exported a pulse signal later on and is sent to single-chip microcomputer, single-chip microcomputer receives this pulse signal and just starts to go into paper money motor 10 and just changeing, Renminbi is sent into the false distinguishing district, promptly infrared projection tube 16, infrared receiving tube 3, laser-transmitting pipe 17, laser pick-off pipe 5, the zone of visible transmission pipe 18 and visible light receiving tube 4 correspondences.Single-chip microcomputer is opened code-disc interruption counting simultaneously.Renminbi enters after the false distinguishing district, respectively the characteristic area of Renminbi is carried out data acquisition by 3 kinds of light sources.At first be constantly emission infrared lights of four infrared transmission pipes 16, this infrared light changes through the power of light after the Renminbi, and the diverse location on the Renminbi is different to the absorption power of infrared light, the infrared receiving tube of receiving on the tabula rasa 3 receives after the corresponding signal, by corresponding amplifying circuit its filtering is amplified, and the signal after will amplifying sends single-chip microcomputer to; Because each position is different to the absorption intensity of ruddiness on the Renminbi, can extract a hundreds of eigenwert of putting by the interval and be linked to be infrared curve, the processing of infrared curve is offered an explanation out the true and false of Renminbi by single-chip microcomputer; The utility model has used 4 road infrared tubes that the eigenwert of Renminbi is gathered, and purpose is exactly as far as possible comprehensively to analyze the characteristic of Renminbi, and the adulterium coin has been played good discriminating effect.Renminbi continues the paper money of going ahead, arrive the position of laser-transmitting pipe 17 and visible transmission pipe 18, laser-transmitting pipe 17 sends laser, this laser radiation will excite the fluorescence of certain wavelength to the eigenwert district of Renminbi, and fluorescence wave plate at first after filtration filters after a part of light, received and convert to electric signal by laser pick-off pipe 5, electric signal sends single-chip microcomputer to, the true and false that single-chip microcomputer is judged Renminbi according to the position and the regularity of distribution of laser electric signal through after amplifying shaping; Present embodiment has adopted three road laser to come acquired signal to be because the laser feature zone position on the Renminbi is fixed to pipe, area is smaller, if only with one road laser collection very possible gather less than, adopt three road laser collections, no matter Renminbi advances paper money from which face, can both guarantee to collect one road laser signal at least, so just guarantee the accurate, reliable of laser false distinguishing.Renminbi is when carrying out the laser signal collection, visible light receiving tube 4 also begins acquired signal, the principle of its acquired signal is similar with infrared principle, visible transmission pipe 18 continuous visible emitting, change has taken place in the power by light after the absorption of Renminbi, and the Renminbi of diverse location is different to the absorption power of visible light, and the visible light receiving tube of receiving on the tabula rasa 4 receives corresponding signal later on its filtering amplification, sends single-chip microcomputer to; Because each position on the Renminbi is different to the absorption intensity of visible light, present embodiment can extract a hundreds of eigenwert of putting by the interval and be linked to be the visible light curve, the processing of visible light curve is offered an explanation the true and false of Renminbi by single-chip microcomputer.Renminbi has passed through transmissive tube 20 places, in-position after all false distinguishing zones, variation had taken place in power after the light of position transmissive tube 20 was blocked, position receiving tube 7 receives after the change in optical signal, convert thereof into electric signal, electric signal can be exported a square wave after amplifying shaping, after single-chip microcomputer receives this square wave, the true and false conclusion of Renminbi that draws according to the false distinguishing district, control the rotating of motor, when being genuine note, motor just changes, banknote is sent detection zone, when being counterfeit money, the motor counter-rotating, banknote is return into the paper money mouth.So far, finished the process of whole false distinguishing.
As can be seen from the above embodiments, the utility model embodiment is by adopting infrared transmission false distinguishing, visible transmission false distinguishing, laser-transmitting false distinguishing and length false distinguishing, can carry out high-precision false distinguishing to Renminbi, adulterium coin and high emulation counterfeit money, also can carry out false distinguishing identification simultaneously the bill class.
The above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
