Method and device for detecting residual paper money in money rolling wheel type temporary storage part as well as ATM (automatic teller machine)

Abstract

The invention discloses a method and a device for detecting residual paper money in a money rolling wheel type temporary storage part as well as an ATM (automatic teller machine). The method comprises the following steps: detecting rotation of a money rolling wheel; when detecting that the money rolling wheel rotates by integral multiple of at least one circle, obtaining a residual detection pulse string signal output by a residual sensor; judging whether the residual paper money exists in the temporary storage part or not according to the number of high / low levels in the residual detection pulse string signal and a preset threshold value. The number of pulses generated by the residual sensor when the money rolling wheel rotates a circle is calculated and compared with the preset threshold value so as to judge whether the residual paper money exists in the temporary storage part or not. According to the method and the device, the threshold value does not need to be specifically set depending on the speed of a motor driving the money rolling wheel, a setting method is simple, and a circular queue does not need to be used for storing a pulse string, so that excessive memory occupation is not needed; in addition, the system time does not need to be used, the system real-time requirement is low, and the accuracy for detecting the residual paper money can be improved.

Description

technical field [0001] The present invention relates to the technical field of financial equipment, in particular, relates to an ATM (Automatic Teller Machine, Automatic Teller Machine, ATM ) machine, method and device for detecting residual banknotes in the roll-type temporary storage section of the banknote rolling machine, and an ATM machine. Background technique [0002] The banknote rolling wheel temporary storage part of the ATM machine is formed by arranging 6 isolation ribs on the outer periphery of the banknote rolling wheel on average. The interval between adjacent isolation ribs is greater than the width of the ribs, and the residual sensors for detecting the remaining banknotes are set opposite to each other. On both sides of the money rolling wheel, when the money rolling wheel is rotating, the residual sensor outputs a corresponding pulse train by detecting the shielding of the detection signal by the six isolation edges. [0003] Such as figure 1 As show...
