Abstract
A banknote counter and detector mechanism that can recognize banknotes of different par values and counterfeit banknotes is provided, which comprises a sensor and a counterfeit banknote recognition circuit, wherein, the sensor is a reflective infrared sensor that can absorb and reflect the special ink material on the banknote, and comprises an emitting part and a receiving part, wherein, the emitting part is a infrared emitting tube that works at a specific wavelength, while the receiving part is an infrared receiving tube that receives infrared rays at a specific wavelength; the counterfeit banknote recognition circuit comprises a reflective infrared sensor, an amplifying circuit, a smoothing circuit, a D/A conversion circuit, and a single-chip, wherein, the sensor reads the signals on the banknote, then, the signals is sent through the amplifying circuit, smoothing circuit to the D/A converter; the signals are converted into digital signals and then sent to the single-chip.
Description
Technical field
The utility model relates to the paper money counter testing agency of a kind of bank note denomination and false distinguishing, especially relates to a kind ofly utilizing some bank note to use on ad-hoc location infrared ray is had the different bank note denominations that the ink material of special absorption reflecting effect discerns and the paper money counter testing agency of false distinguishing.
Background technology
The infrared authentication detection technology of all paper money counters of domestic production at present is to utilize the special paper material of making bank note different with plain paper to the infrared ray absorbing reflection, reaches the purpose of false distinguishing.But since the new and old difference of paper, contaminated degree difference, and the reliability of this technology is relatively poor, in application, is difficult to really play effect.In addition, the identification of different denominations bank note is to rely on sensor to read its specific size to differentiate.
Summary of the invention
Technical problem to be solved in the utility model provides a kind ofly to be utilized some bank note to use on ad-hoc location to have the ink material of special absorption reflecting effect to discern the paper money counter testing agency of different bank note denominations and false distinguishing to infrared ray.
For solving the problems of the technologies described above, the paper money counter testing agency of different bank note denominations of identification provided by the utility model and false distinguishing comprises sensor and identification false distinguishing circuit, described sensor is a kind of can the absorption and the oil reflection-type infrared sensor of ink material of reflection bank note, the reflection-type infrared sensor comprises and transmits and receives two parts, radiating portion is the infrared transmitting tube of specific wavelength, receiving unit is for receiving the infrared receiving tube of specific wavelength, described identification and false distinguishing circuit comprise the reflection-type infrared sensor, amplifying circuit, current rectifying and wave filtering circuit, D/A converting circuit and single-chip microcomputer, sensor reads the signal process amplifier on the bank note, sending into digital to analog converter behind the current rectifying and wave filtering circuit is transformed into digital signal and sends into single-chip microcomputer, send work order for the relevant functional part of paper money counter by single-chip microcomputer, implement relevant operation.
Because the pattern difference of different currency, the printing of different denomination, printing ink at the spectrum difference, this printing ink can not be recognized under normal optical or other light sources, infrared and receiving sensor have been installed on the paper money counter, machine operational analysis as calculated, identification reaches false distinguishing and the purpose of discerning different denominations by the pattern of this specialty inks printing, and engineering reliability is good.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Description of drawings
Fig. 1 is the circuit block diagram of a kind of embodiment of the utility model.
Fig. 2 is the electrical schematic diagram of Fig. 1.
Embodiment
Embodiment as shown in Figure 1 and Figure 2, this discerns the paper money counter testing agency of different bank note denominations and false distinguishing, comprise sensor and identification false distinguishing circuit, described sensor is a kind of can the absorption and the oil reflection-type infrared sensor A1 of ink material of reflection bank note, reflection-type infrared sensor A1 comprises and transmits and receives two parts, radiating portion is the infrared transmitting tube of specific wavelength, receiving unit is for receiving the infrared receiving tube of specific wavelength, and infrared transmitting tube and infrared receiving tube encapsulation one are installed on the stranding paper money plate of paper money counter to read the identification signal on the bank note.Detect effect for improving, present embodiment is provided with two reflection-type infrared sensors, is installed in the both sides of rubbing the paper money plate with the hands respectively, the general pseudo-60-75 millimeter of the distance between two pipes.Described identification and false distinguishing circuit comprise reflection-type infrared sensor A1, amplifying circuit U1D, current rectifying and wave filtering circuit, D/A converting circuit U1 and singlechip CPU.Resistance R 80 among the figure, R24 is respectively the current-limiting resistance of infrared emission and acceptance, sensor reads the pattern signal that is printed by specialty inks on the bank note and amplifies through amplifying circuit U1D, sending into D/A converting circuit U1 behind the current rectifying and wave filtering circuit rectifying and wave-filtering that R26, R27, C17 form becomes digital signal and sends into singlechip CPU, through the software processes of setting, just can reach false distinguishing and the currency of discerning different denominations.
