点钞机中夹版人民币的双波长反射比检测

Double wavelength reflectance detection of mix format RMB-banknote in currency count machine

提出了夹版人民币的双波长反射比检测方法。在点钞机中使用二组波长传感器来检测出一叠同版 10 0圆面额人民币中夹入的其它币种。经实测 ,其精度可达每 10 0张 10 0圆 (同版 )中夹入 2张其它币种点 2 0次 ,漏检不超过一次 。

The detecting method of mix format RMB-banknote based wavelength division principle is put forward. Two pairs of wavelength division sensors are used in a currency count machine. The mix format banknote mixed in banknote RMB 100-yuans are detected. Experimental results show that when two pieces of other format banknote are mixed in one hundred pieces of 100-yuan-RMB-banknotes, if they are counted 20 times, the times of mix format leakage detection is no more than 1. It plays a very important role in finance.
