Description
Technical field
The utility model relates to a kind of equipment of the identification note true and false, specifically relates to a kind of bank note transmission detector.
Background technology
RMB-banknote discriminating device is in the market the true and false being differentiated Renminbi by infrared ray sensor substantially.But this identification method easily occurs careless mistake, such as after long-term use, surface becomes easily infected by dirt to some Renminbi, can produce certain impact to the result that infrared ray is differentiated.Obviously, in the application of reality, be only used for detecting the feature of banknote paper, Detection results is not very desirable.
Summary of the invention
The object of the present invention is to provide a kind of bank note transmission detector, this transmission detector, based on the difference of true and false coin transmittance, distinguishes genuine note and counterfeit money.
The technology used in the present invention solution is:
A kind of bank note transmission detector, comprise the laser module sending light beam, the constant-current supply of powering for laser module and photoresistance, described photoresistance be positioned at laser module send on the travel path of light beam, photoresistance connects ohmmeter, is provided with bank note rest area to be measured between laser module and photoresistance.
Further, this detector also comprises housing, described housing comprises the first body and the second body, the light beam that described laser module sends passes the axle center of the first body and the second body, light shield is provided with between the head and laser module of the first body, the afterbody of the first body is provided with paper currency detection insert port, transition section is provided with between the afterbody and the head of the second body of the first body, described photoresistance is positioned at the second body, and the afterbody of the second body is provided with light tight filling material.
Further, the diameter of described first body is 0.5mm, and the diameter of the second body is 3mm.
Further, described constant-current supply comprises monolithic stabilized voltage supply and the first resistance.
Further, described laser module comprises semiconductor laser diode and optical lens.
Advantageous Effects of the present invention is:
Due to the difference of true and false coin performance and the difference of same bank note different parts performance, especially the difference of transmittance, the light effects be blocked under same light source irradiation is different and transmission obtains light is also different, the resistance of different light effects on photoresistance has larger impact, the utility model utilizes such performance to distinguish genuine note and counterfeit money just, has that accuracy is high, highly versatile, structure are simple, volume is little, low cost and other advantages.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail:
Fig. 1 is structural principle schematic diagram of the present utility model.
Embodiment
By reference to the accompanying drawings, a kind of bank note transmission detector, comprise send light beam laser module 1, for laser module 1 power constant-current supply 2 and photoresistance 3.Laser module 1 is made up of semiconductor laser diode and optical lens.Its feature sends point-like continuous laser beam, optical wavelength 650nm, and light velocity frequency is single, and directivity is fabulous; Have power consumption little to Renminbi do not cause damage and also sensitivity relatively high.Described constant-current supply 2 comprises monolithic stabilized voltage supply 201 and the first resistance 202.Described photoresistance 3 be positioned at laser module 1 send on the travel path of light beam, photoresistance 3 connects ohmmeter 4.Bank note rest area to be measured is provided with between laser module 1 and photoresistance 3.
As to further improvement of the utility model, this detector also comprises housing, and described housing comprises the first body 5 and the second body 6, and the light beam that described laser module 1 sends is through the axle center of the first body 5 and the second body 6.Between the head and laser module 1 of the first body 5, be provided with light shield 7, the afterbody of the first body 5 is provided with paper currency detection insert port.Transition section 8 is provided with between the afterbody and the head of the second body 6 of the first body 5.Described photoresistance 3 is positioned at the second body 6, and the afterbody of the second body 6 is provided with light tight filling material 9.The diameter of the first body 5 is 0.5mm, and the diameter of the second body 6 is 3mm.
Further, the model of above-mentioned monolithic stabilized voltage supply 201 is LM317L, and the resistance of the first resistance 202 is 620 Ω, and continuous current is 20mA, and the laser beam illumination that laser module 1 is sent stablizes the impact not by external voltage change and temperature variation.The model of laser module 1 is FU650AD5-C6.5, is made up of semiconductor laser diode and optical lens, the light pencil energy sent can cover far away to hundreds of rice, still brightness is very high for the hot spot of generation.Photoresistance 3 model is LXD3526, and volume sluggishness high time constant is little.Ohmmeter 4 is 4 bit digital ohmmeters, and model is MY65.
By the utility model transmission detector, test experience is carried out to bank note, find that the transmittance difference of genuine note and counterfeit money is larger.In most areas, genuine note is better than counterfeit money transmittance.Thus the true and false of Renminbi can be judged by the analysis of the data obtained bank note transmission detector, then most of numerical value is lower for the higher counterfeit money of the good relative value of genuine note transmittance.
The relevant technologies content do not addressed in aforesaid way is taked or uses for reference prior art to realize.
It should be noted that, under the instruction of this instructions, those skilled in the art can also make such or such easy variation pattern, such as equivalent way, or obvious mode of texturing.Above-mentioned variation pattern all should within protection domain of the present utility model.
