[0002] At present, the bill feature value detection system detects the feature value on the bill, but after the detection system is used for a period of time, the light emitted by the detection system will attenuate, or the detection window will be dirty, and the result is the detection feature. The accuracy of the value is reduced, and the detection system needs to be calibrated regularly to reduce this effect, which leads to a lot of trouble

The invention provides a system for detecting the characteristic value of a note and a method for detecting the characteristic value of the note. The system includes a fixing panel which includes a first detection window; a moving panel which includes a sampling block and a second detection window, wherein the sampling block and the second detection window move along with the moving of the moving panel; a detection apparatus which is intended for, when it is determined that the sampling block moves to the position corresponding to the first detection window along with the moving of the moving panel, detecting the testing value of the sampling block, based on the testing value, and computing a light source modification coefficient, and when it is determined that the second detection window moves to the position corresponding to the first detection window along with the moving of the moving panel, based on the initial characteristic value of the note, acquiring the transmission speed of the note being transmitted to the first detection window, and based on the initial characteristic value, the transmission speed and the light source modification coefficient, determining the final characteristic value of the note. According to the technical solution of the invention, the system and the method effectively increase the accuracy in detecting the characteristic value of the note.
Description
technical field [0001] The invention relates to the technical field of bill detection, in particular, to a detection system of bill feature values and a detection method of bill feature values. Background technique [0002] At present, the detection system of the characteristic value of the bill detects the characteristic value on the bill, but after the detection system is used for a period of time, the light emitted by the detection system will be attenuated, or the detection window will be dirty, and the result is the detection feature. The accuracy of the value is reduced, and this effect needs to be reduced by periodically calibrating the detection system, which is very troublesome. [0003] Therefore, how to improve the detection accuracy of the eigenvalues of the bills while avoiding the regular calibration of the detection system by the user has become an urgent problem to be solved. SUMMARY OF THE INVENTION [0004] Based on the above problem, the present inv...
