Abstract
The utility model discloses a counterfeit note recognizer, comprising four parts: a light source power supply, an ultraviolet source, a sensor package and a detecting and alarm control circuit. The utility model is composed of an ultraviolet source, a sensor element, a color difference correction filter, a structural slab, a housing, an alarm lamp, a buzzer, a switch, a connecting line, a resistance, a capacitor, an operational amplifier, a solid state relay, a not gate, etc., wherein, the note angle of the installation of the sensor package 3 and the detected bank note is 30 DEG-60 DEG, and the sensor package 3 and the ultraviolet source 1 are arranged on the same side. When the counterfeit is recognized by the automatic counterfeit note recognizer, the recognizer gives a shutdown control signal and sent out the audible and visual alarm. The utility model has the advantages that the automatic counterfeit note recognizer can detect the counterfeit with various editions and can be matched with a currency count machine or used singly.
Description
The utility model relates to a kind of counterfeit money identification device.
Differentiate that at present counterfeit money has three kinds of methods basically.A kind of method is an artificial cognition, and it is to rely on people's experience to come counterfeit money is differentiated.Second method is called the Static Detection method, and it is to use instrument Renminbi is detected one by one, and above-mentioned two kinds of methods differentiate that speed is slow.Also has a kind of dynamic auto identification device at present, it can carry out detection of dynamic continuously to Renminbi, its principle is by detecting through the fluorescence light intensity Renminbi to be discerned, counterfeit money has multiple version not, for example mechanism, duplicating, inscription rubbings etc., their fluorescence intensity are all different, and this has just caused the discriminating precision not high, poor reliability is subjected to ambient light interference big.
The purpose of this utility model provides a kind of automatic identification device that is different from said structure, and it is to come counterfeit money is differentiated by detection of reflected fluorescence aberration and fluorescence intensity.
Technical solution of the present utility model such as Fig. 1-shown in Figure 5.It is made up of light source power, ultraviolet source, sensor module, testing circuit four parts, includes ultraviolet source 1, ultraviolet source power supply 2, sensor module 3, detection alarm control circuit board 4, spectrum correction optical filter 5,6, photo electric sensitive element 7,8, structural slab 9, shell 10, alarm lamp 11, K switch, line 12,13,14, detected bank note 15, resistance R
