Problems solved by technology
[0003] The purpose of the present invention is to provide a non-contact method for dynamically measuring the area of currency, which can sort out currency of different denominations according to the characteristics of different areas of currency of different denominations, so as to solve the problem of small currency being inserted into currency with a large area during the banknote counting process. The problem that area currency is not easy to be found, so as to avoid unnecessary economic losses to merchants or customers

Embodiment Construction
[0028] The non-contact method of the present invention dynamically measures currency area, and the detection mechanism of a currency area is set between the money-in mechanism and the money-out mechanism mechanism of money counter; Through the calculation of the vertical and horizontal signals of the currency under test, the area value of the currency under test can be accurately obtained, and the dynamic measurement of the currency area can be realized in the process of counting money, so as to distinguish two or more different areas currency.
[0029] When sorting two kinds of currencies, the length and width difference of the two sorted currencies should be greater than or equal to 5 millimeters, and the accuracy of measuring the area of a single currency should be less than 5% of the area of the entire currency. The measurement of the present invention The speed is: 1000 sheets / min.
[0030] As shown in Figures 1, 2, 3, and 4, the detection mechanism of the present in...

A money-note area tester (NAT) is set between the input and output mechanisms of the note counting machine. NAT measures accurately the note acreage to distinguish two or more kinds of notes with different acreages. NAT includes the pressing note wheel, the pressed wheel and at least a row of piercing type infrared emitter / receiver pair (PIEP) fixed in parallel with the pressing / pressed wheel axes. There is a pair of code disk and deputy code disk on the pressing note wheel axis. At least two pairs of piecing type infrared emitting / receiving counting light couples are fixed between PIEPs. According to the character that the different denomination notes (DDN) possess different note acreage, DDN are easily distinguished. This solves the problem of sandwiching the small acreage note into a stack of big acreage notes that is hard to be discovered. It can prevent the seller or the buyer from economic losing.
Description
technical field [0001] The invention relates to currency in the financial field, and relates to a method for distinguishing large and small currency, in particular, a method for non-contact dynamic measurement of currency area. Background technique [0002] Banks, securities and other financial places usually put banknotes of the same denomination into the banknote counting machine in the banknote counting process, and generally there will be no mistakes. Certainly, occasionally small-value banknotes are sandwiched into large-value banknotes without being discovered. Once the operator is negligent, it will inevitably bring economic losses to the encounter (including merchants and customers). This is due to the fact that existing banknote counting equipment itself does not possess the function of distinguishing large and small denomination banknotes. Therefore, people are always looking for a method that can make up for this defect. Contents of the invention [0003] The p...
