Abstract

The invention relates to a note width and distance detecting and quantity calculating method and device. The method comprises the following steps of: a. charging notes into a transmission passage for running; b. carrying out data sampling on an infrared sensor in the transmission passage according to fixed clock frequency and respectively recording high level frequency and low level frequency of a sampled infrared sensor signal by a detecting unit; c. calculating the note width and distance through pulse number; and d. carrying out note calculation of the calculated pulse number in the range of the preset note width pulse number. The device comprises a plurality of infrared sensors, a multi-channel selector, an analog-to-digital converting circuit, a timer and a data processing and logic control chip.

Description

technical field [0001] The invention relates to a method and a device for detecting the width and spacing of banknotes and counting the number of banknotes in the process of banknote transaction or sorting. Background technique [0002] When the all-in-one deposit and withdrawal machine performs banknote transactions or the sorting machine performs banknote sorting, it is necessary to carry out residual detection and counting statistics on the banknotes in the channel. In the prior art, it is judged whether the infrared sensor is blocked or not to judge the remaining banknotes and count the number of sheets, or to count the rising and falling edges of the high and low levels generated by the infrared sensor being blocked or not. Its disadvantage is that it is impossible to judge the overlapping of banknotes, jamming, or even omission of bills, resulting in short payment. Contents of the invention [0003] The object of the present invention is to provide a method and devi...
