Embodiment 1

[0028] Figure 1a It is a flow chart of a method for detecting banknotes with adhesive tape provided by Embodiment 1 of the present invention. This embodiment is applicable to the detection of banknotes with almost the entire adhesive tape attached. This method can be performed by a detection device for banknotes with adhesive tape. The device It can be realized by means of software and / or hardware, and the device can be integrated in any equipment with banknote identification function, such as typically banknote validators and banknote counters. Specifically include the following steps:

[0029] S110. According to the thickness data of banknotes to be detected respectively obtained by multiple channels of the thickness sensor, determine an average value of the thickness data corresponding to each channel.

[0030] In this embodiment, the thickness sensor is provided with a row of sensor units arranged side by side laterally, and one sensor unit corresponds to one channel. Th...

Embodiment 2

[0044] figure 2 It is a flow chart of a detection method for tape banknotes provided by an embodiment of the present invention. On the basis of the above embodiments, this embodiment extracts at least one mean value of the thickness data according to preset rules, and calculates the at least one An average value optimization of the thickness data mean value is: sort the size of the thickness data mean value, and record the serial number of each channel after sorting; extract the thickness data mean value corresponding to the preset channel serial number, and calculate the predetermined value. Set the mean value of the mean value of the thickness data corresponding to the serial number of the channel.

[0045] Such as figure 2 As shown, the method of the present embodiment includes the following steps:

[0046] S210, according to the thickness data of banknotes to be detected respectively obtained by multiple channels of the thickness sensor, determine the mean value of the...

Embodiment 3

[0055] image 3 It is a flow chart of a detection method for tape banknotes provided by an embodiment of the present invention. On the basis of the above embodiments, this embodiment determines whether the banknote to be detected is The optimization of all-channel adhesive tape banknotes is as follows: calculate the difference between the maximum value and the average value; calculate the product of the average value and the preset coefficient; compare the difference with the product, and determine the value according to the comparison result. Describe whether the banknote to be detected is an all-channel adhesive tape banknote.

[0056] Such as image 3 As shown, the method of the present embodiment includes the following steps:

[0057] S310. According to the thickness data of banknotes to be detected respectively obtained by multiple channels of the thickness sensor, determine an average value of the thickness data corresponding to each channel.

[0058] S320. Sorting th...

Abstract

The embodiment of the invention discloses an adhesive tape-glued paper money detection method and device. The method comprises the steps of according to thickness data, which is obtained by a plurality of channels of a thickness sensor, of paper money to be detected, determining a thickness data mean value corresponding to each channel; extracting at least two thickness data mean values accordingto preset rules, and calculating a mean value of the at least two thickness data mean values; determining a maximum value of the thickness data mean values; and determining whether the paper money tobe detected is full-channel adhesive tape-glued paper money or not according to the mean values and the maximum value. According to the technical scheme provided by the invention, a problem that onlypaper money glued with part of an adhesive tape can be detected is solved, and the detection on the adhesive tape-glued paper money with a whole adhesive tape nearly covering the paper money length ina short edge direction can be realized.

Description

technical field [0001] The embodiment of the present invention relates to banknote processing technology, in particular to a method and device for detecting tape banknotes. Background technique [0002] The banknotes in circulation may have adhesive tape on the surface due to various reasons. These banknotes pasted with tape (ie tape banknotes) will affect the normal judgment of the banknotes during the process of counting and checking banknotes, and will also be jammed and destroyed when they are destroyed. Therefore, it is more important to identify tape banknotes. [0003] In the prior art, there is a scheme of using the thickness of banknotes to realize tape banknote detection. It uses the average value of the channel thickness of the thickness sensor of a single channel as the judgment threshold to locate the suspected tape area of ​​the channel, and accurately locates the tape position through edge detection and tape thickness. , so as to realize the detection of tape...
