Description
Technical Field
The utility model relates to a banknote counter, in particular to a device for counting and identifying banknote by utilizing a discrete element optical scanning system to optically scan hidden images and visible images of the banknote. The utility model can be used in banknote counting machines with front or back banknote loading systems for counting banknotes, identifying value and verifying authenticity of banknotes.
Background
The banknote has an image in the visible spectrum and a hidden image visible in infrared light. For visual image recognition of banknotes, a visible spectral range scanning system is used. For hidden image recognition of banknotes (visible in infrared light), an infrared spectral range scanning system is used. In order to simultaneously identify the visible and hidden images of the banknote, a combined scanning system is used, which can simultaneously scan the visible and hidden images of the banknote.
The banknote counter for identifying the value of the banknote has the following working principle: the banknotes are placed in a paper feeding tray and transported to a counter section where they are passed through an optical scanning system to evaluate their response to visible and infrared exposure. The response is generated by specific inks and protective elements incorporated into the banknote structure, which are sensitive to certain light types.
There are solutions that allow identification of banknotes using CIS scanners (contact image sensors). Such a solution requires the integration of one or two CIS scanners and one digital-to-analog processor in the device, which results in a high cost of the overall system. Such a solution is not feasible in low-end cabinets.
The present utility model solves the above-mentioned problems. The authors propose to equip banknote counting machines with discrete element optical systems for banknote scanning and identification. The scheme has higher cost performance, and can realize the paper money identification function at a low-grade counter.
Disclosure of Invention
The technical scheme adopted by the utility model is as follows: a banknote counter for identifying banknotes by means of a discrete element optical scanning system, characterized in that: comprising a paper feed pocket, a paper feed mechanism, a central processor main board, a banknote path section, in which a receiving pocket of an additional discrete element optical scanning system is mounted, wherein the scanning system of the banknote counter has radiating and receiving elements, wherein signals characterizing information measured with respect to the receiving elements are transmitted to the main board of the central processing unit for processing in order to sort banknotes into categories based on the banknote values assigned to them by software.
The beneficial effects of the utility model are as follows: the technical result of the present utility model is the scanning of banknote images visible in both infrared and visible light using a discrete element optical scanning system.

Detailed Description
As shown in fig. 1 to 7, the banknote counter of the present utility model has a pocket for loading banknotes, a banknote path section, an optical scanning system, an electronic board with an analog-to-digital converter with a processor, and a acceptor pocket.
Depending on the complexity of the model, the optical scanning system may be modified in that the optical scanning system may scan a hidden infrared image of a banknote, a visible banknote image, or in a combined version, scan an image under both hidden infrared light and hidden infrared light. While being visible.
Scanning the banknote concealed image in infrared light uses an infrared radiating element having a wavelength of 850nm, 940nm.
Scanning the banknote image under visible light uses a white light radiating element. An optical scanning system in a more complex system may have RGB (red, green, blue) radiating elements in the visible spectrum.
After loading the banknote into the counter feed pocket (26), the feed mechanism (31) feeds the banknote to the counter portion (29) where the optical banknote scanning system (33) is located. Subject to the complexity of the scanning system (see fig. 1, 2, 3, 4), digital image values of the following notes are obtained.
The present utility model has various embodiments, and is described in detail below.
Example 1, as shown in figure 1, such an optical scanning system can obtain infrared digital image values of banknotes in the 850nm spectral range.
Example 2, as shown in figure 2, such an optical scanning system can obtain infrared digital image values of banknotes in the 850nm and 940nm spectral ranges.
Example 3, as shown in fig. 3, such an optical scanning system can acquire infrared digital image values in the 850nm spectral range and visible digital image values for banknotes in the visible spectral range.
Example 4, as shown in fig. 4, such an optical scanning system can acquire infrared digital image values in the 850nm spectral range and color digital image values for banknotes in the visible spectral ranges red, green, blue (RGB).
The digital image values of the banknote obtained are processed by a processor board (32) to compare the digital image values obtained with reference values stored in a system memory. If the digital value of the image obtained corresponds to any value stored in the system, the image acquires the banknote value assigned to the digital image in the system software. This is the way in which the value of the banknote is identified. The more complex the scanning system, the more accurate the result, since multiple digital image values of the banknote are to be identified simultaneously. The count result is then displayed on a point display (27) and the banknote is moved to a receiving pocket (30).
The technical result of the present utility model is the scanning of banknote images visible in both infrared and visible light using a discrete element optical scanning system.
