Abstract

본 발명은 지폐식별기의 지폐식별방법에 관한 것으로, 특히 지폐가 지폐투입구에 투입되면 지폐를 지폐식 별부 내부로 로딩하기 위해 모터를 구동하는 모터구동단계로 이루어진 종래의 지폐식별방법에 있어서, 상기 모터가 구동함에 따라 지폐가 지폐식별부의 검사위치에 도달하였는가를 판단하는 위치판단단계와, 이 위치판단단계의 판단에 따라 지폐가 검사위치에 도달하면 쎈서유니트의 발광소자가 빛을 발광하고 소광소자가 투과된 빛을 수광한 후 수광소자의 출력을 일정한 샘플링 주파수에 의해 샘플링 단계와, 이 샘플링단계에서 샘플링된 데이타를 디지탈 신호로 변환하는 A/D 변환단계와, 그리고 이 A/D 변환에 의하여 디지탈 신호로 변환된 데이타를 메모리에 저장되어 있는 진폐의 데이타와 비교하여 검사대상 지폐의 진위를 판단하는 단계로 이루어져, 지폐가 지폐식별부를 이동할때 발광소자가 빛을 발산하고 수광소자가 그 빛을 수광하여 만들어지는 시계열 데이타를 메모리에 저장되어 있는 진폐의 동일한 검출위치에서 얻은 시계열 데이타와 비교하여 진폐여부를 식별함으로써 지폐식별기의 지폐인식율을 향상시키는 효과가 있다.The present invention relates to a banknote identification method of the banknote identifier, in particular, in the conventional banknote identification method consisting of a motor driving step of driving the motor to load the banknote into the banknote identifier when the banknote is inserted into the banknote, the motor The position determination step of judging whether the banknote has reached the inspection position of the banknote identification unit, and when the banknote reaches the inspection position according to the judgment of the position determination unit, the light emitting device of the unit emits light and After receiving the transmitted light, the output of the light receiving element is sampled by a constant sampling frequency, an A / D conversion step of converting the data sampled in this sampling step into a digital signal, and digital by this A / D conversion. Determining the authenticity of the banknote to be tested by comparing the data converted into a signal with the data of the pneumoconiosis stored in the memory When the banknote moves through the banknote identification unit, time-series data generated by the light emitting device emits light and the light-receiving device receives the light is compared with time series data obtained at the same detection position of the pneumoconiosis stored in the memory to identify whether it is pneumoconiosis. By doing so, there is an effect of improving the bill recognition rate of the bill identifier.

Claims

In the banknote identification method of loading a banknote inserted into a banknote input hole into a banknote identification unit by a motor drive, a position determination step of judging whether the banknote reaches the inspection position of the banknote identification unit as the motor is driven, and this position determination step A sampling step of sampling the output of the light receiving element by a constant sampling frequency after the light emitting element of the sensor unit emits light and receives the transmitted light when the banknote reaches the inspection position according to the judgment of An A / D conversion step of converting the sampled data into a digital signal, and comparing the data converted into a digital signal by the A / D conversion with the attenuated data stored in the memory to determine the authenticity of the banknote to be tested. Banknote identification method of the bill identifier, characterized in that consisting of a step.
