Embodiment Construction
[0036] The embodiments of the present invention will be further described in detail below in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the embodiments of the present invention, rather than to limit the embodiments of the present invention. In addition, it should be noted that, for the convenience of description, the drawings only show some but not all structures related to the embodiments of the present invention.
[0037] refer to figure 1 , figure 1 It is a schematic flowchart of a method for detecting the magnetic properties of dancer rollers provided by an embodiment of the present invention.
[0038] Such as figure 1 As shown, the method for detecting the magnetism of the dancer roller includes:
[0039] Step 101, collect the magnetic data of test paper in 18 channels of money detector;
[0040] Specifically, acquire background data of 18 magnetic channels, that is, col...

The embodiment of the invention discloses a method and device for detection of floating roller magnetism. The method comprises: collecting the magnetism data of test papers on the 18 channels of a money detector; calculating the maximum value and the minimum value of the amplitude of the magnetism data of each channel, and calculating the difference of the maximum value and the minimum value; if the difference does not exceed a preset difference threshold, obtaining the number of the magnetism data points which are not located in a preset magnetism background data range in the magnetism data of the test papers; and if the number of the magnetism data exceeds the setting number, determining that the magnetism floating roller is magnetized. Through calculation of the difference between the maximum value and the minimum value of each channel of the banknotes to be detected and the number of the magnetism points of each channel exceeding the background data range, the method and device for detection of the floating roller magnetism can rapidly and effectively determine whether the floating roller is abnormal or not and ensure the accurate collection of the banknote magnetism signals.
Description
technical field [0001] The embodiments of the present invention relate to the technical field of detecting the magnetism of floating rollers, and in particular to a method and device for detecting the magnetic properties of floating rollers. Background technique [0002] In the cash ATMs used by financial institutions, as a recycle machine for cash processing, in order to ensure the authenticity of cash, a paper currency identification device is installed in the recycle machine to identify whether the banknotes deposited and withdrawn are It is true, but the magnetic ink is printed at the predetermined position in the banknote, so using the magnetic ink on the banknote to identify the authenticity has become one of the many detection methods. [0003] However, in the process of detecting magnetism, it will be affected by many aspects, such as: surrounding magnetic parts, bearings supporting rotating parts, etc. will cause interference to magnetic detection, affecting the acc...
