Abstract
A paper currency discrimination device with spectrum detection arrays comprises an ultraviolet light source which is mounted in a currency counting and detecting machine in the place capable of radiating paper currency, optical filters and a fluorescent sensor are arranged in the place capable of receiving reflected light of the paper currency, the fluorescent sensor is connected with a fluorescent signal processing circuit, a phosphorescent sensor is further arranged behind the optical filters and connected with a phosphorescent signal processing circuit, an infrared light source is additionally arranged in the place capable of radiating the paper currency, and an infrared sensor is correspondingly arranged in the place capable of receiving the transmission light of the paper currency and connected with an infrared signal processing circuit, so as to form various spectrum detection array mechanisms. The paper currency discrimination device achieves various spectrum detection on the fluorescent effect, the phosphorescent effect and the infrared transmission characteristic of the paper currency radiated by the ultraviolet light, has comprehensive and reasonable spectrum detection indexes, is sensitive and reliable in discriminating counterfeit currency from genuine currency and greatly improves the discrimination performance of the currency counting and detecting machine.
Description
Technical field: the utility model relates to the spectral detection false-identifying device that uses in a kind of currency counting and detecting machine tool.
Background technology: the light that bank note reflects under UV-irradiation has the fluorescent effect signal of fluorescent effect and plain paper has any different, and the device that can detect fluorescent effect all is installed in the general paper money counter is used for false distinguishing.Bank note is to adopt the specialty inks printing, and many positions also can produce allochromy under UV-irradiation, and the allochromy of counterfeit money is then considerably less, and the facility that are equipped with the allochromy detection simultaneously are few.And many paper money counters also are provided with the infrared signature pick-up unit, but are mostly to detect bank note infrared external reflection light characteristic, and in fact because true and false coin is obviously different to the absorbability that infrared light sees through, the false distinguishing discrimination of infrared transmission spectrum is more obvious.
Summary of the invention: to the deficiency of prior art, the utility model provides a kind of spectral detection array bank note false-identifying device that can carry out multiple spectral detection to bank note.
The utility model comprises the ultraviolet source that is installed in the currency counting and detecting machine tool, can shines the bank note place; Then be provided with optical filter and fluorescent optical sensor can receiving bank note reflected light place; Fluorescent optical sensor connects the fluorescence signal treatment circuit; Behind optical filter, also be provided with the phosphorescence sensor, this phosphorescence sensor connects the phosphorescent signal treatment circuit; Can shine the bank note position place and be provided with infrared light supply in addition, can receive the corresponding infrared light transducer[sensor that is provided with in bank note transmitted light place, infrared light transducer[sensor connects the infrared signal treatment circuit, constitutes multiple spectral detection array mechanism.
The utility model carries out multiple spectral detection to fluorescent effect, allochromy and the infrared transmission characteristic of bank note under UV-irradiation; Spectrum false distinguishing index comprehensive and reasonable; Differentiation to true and false coin is reliably responsive, can improve the false distinguishing performance of currency counting and detecting machine tool greatly.
Further specify the utility model below in conjunction with accompanying drawing and embodiment.
Description of drawings: Fig. 1 is the structural principle synoptic diagram of embodiment.
Embodiment:Embodiment: as shown in the figure, ultraviolet source 1 is installed in the currency counting and detecting machine tool, can shines bank note 10 places, then is provided with optical filter 2 and fluorescent optical sensor 3 can receiving bank note 10 reflected light places, and fluorescent optical sensor 3 connects fluorescence signal treatment circuits 5.Behind optical filter 2, also be provided with phosphorescence sensor 4, this phosphorescence sensor 4 connects phosphorescent signal treatment circuit 6.Can shine bank note 10 positions and be provided with infrared light supply 7 in addition, can receive the corresponding infrared light transducer[sensor 8 that is provided with in bank note 10 transmitted light places, infrared light transducer[sensor 8 connects infrared signal treatment circuit 9, constitutes multiple spectral detection array mechanism.
Fluorescent optical sensor 3 and phosphorescence sensor 4 all can have a plurality of, and corresponding optical filter 2 also can have multi-disc, makes things convenient for the layout of fluorescent optical sensor 3 and phosphorescence sensor 4 like this.Present embodiment is integrated into multispectral overall treatment circuit with fluorescence signal treatment circuit 5, phosphorescent signal treatment circuit 6 and infrared signal treatment circuit 9, can strengthen the integrated level of entire circuit like this, and operation efficiency is higher.
During work; Ultraviolet source 1 shines on the bank note 10; Produce fluorescent effect and allochromy; The light of its reflection produces induced signals through making fluorescent optical sensor 3 and phosphorescence sensor 4 behind the optical filter 2, outputs to respectively then that calculation process becomes corresponding spectral signature signal in fluorescence signal treatment circuit 5 and the phosphorescent signal treatment circuit 6, offers the currency counting and detecting machine tool and compares false distinguishing.Similarly, infrared light supply 7 shines on the bank note 10, and the transmitted ray that penetrates after the absorption makes infrared light transducer[sensor 8 produce induced signals, outputs to then that calculation process becomes corresponding spectral signature signal in the infrared signal treatment circuit 9.
