Embodiment Construction
[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0025] Such as figure 1 As shown, a banknote jam judgment system includes a sensor unit 101 , a banknote information storage unit 102 , a jam threshold calculation unit 103 and a jam status judging unit 104 .
[0026] The sensor unit 101 includes a plurality of sensors arranged on the banknote conveying passage at certain intervals along the banknote conveying direction. The distance of the front end of an arriving note relative to itself until the front end of t...

The invention provides a paper money blockage judging system and a paper money blockage judging method. The paper money blockage judging system comprises a sensor unit, a paper money information storage unit, a paper money threshold value computing unit and a paper money blockage stage judging unit. The paper money threshold value computing unit can compute a threshold value according to practical length of paper money and practical distance among sensors, so that paper money blockage is judged according to the practically computed threshold value when being judged by the paper money blockage judging unit. The papery money blockage judging system and the paper money blockage judging method have the advantages that a dynamic papery money blockage judging technology based on the threshold value variable along with the paper money and the sensors is provided, measuring precision can be improved, and reliability can be guaranteed.
Description
technical field [0001] The invention relates to a sheet medium conveying state monitoring technology, in particular to a bill jam judging system and method during bill conveying in an ATM core. Background technique [0002] In the prior art, a fixed threshold is generally adopted as a criterion for judging jamming of banknotes during transport. Such as Figure 4 , Figure 5 and Figure 6 As shown, in a simplified banknote conveying system, 101 is the conveying direction of the banknote, 102 is the banknote conveying channel, 103 and 104 are detection sensors arranged on the banknote conveying channel, 105 is the banknote being transported, and S is the sensor 103 and the distance between the sensor 104, L is the length of the banknote, D is the distance between the front end of the banknote and the sensor 104. The jam judgment method with a fixed threshold is: when the banknote covers the sensor, the jam threshold is K times the length of the longest banknote, and K is a ...
