Description

Banknote area scanner

This new model is related to a banknote roll area scanner for detecting the remaining area of a damaged banknote roll.

According to the "Standards for the Collection and Exchange of Dirty, Damaged and Unsuitable Banknotes and Coins", if people hold damaged banknotes, they can go to the teller counter of the Bank of Taiwan to exchange them for bills. The teller usually uses a transparent acrylic measuring plate or a normal banknote folded in half for comparison to measure the remaining proportion of the damaged banknote. If the remaining proportion is more than three-quarters, it can be exchanged in full; if it is less than three-quarters but more than one-half, it can be exchanged at half the amount; if it is less than one-half, it will not be exchanged. However, these methods may not be effective for detecting banknotes that are stained by water, smoked, torn by insects, or damaged in non-square shapes.

Banknotes have unique characteristics. They are made of special paper that is tougher than ordinary paper and is not easily bitten by insects or soaked in water. In addition, banknotes do not fluoresce when exposed to ultraviolet light, while ordinary paper usually fluoresces due to bleaching. In order to identify the authenticity, fluorescent ink is usually added when banknotes are printed. This ink will react under the illumination of LEDs of different wavelengths. In addition, magnetic inks, color-changing inks, metallic inks, gravure printing and other technologies are also used. These technologies can not only be used for anti-counterfeiting, but also increase the visual effects and tactile properties of banknotes and improve security.

The banknote verification and counting machine is an important tool for detecting the authenticity of banknotes. It consists of a banknote input module, an electronic inspection and counting module, a banknote output module, and a motor drive module. The banknote verification and counting machine can efficiently process banknotes at a speed of 600 to 1,000 per minute. The banknote verification machine uses infrared detection technology to read the special spectrum of banknote ink and conducts inspections through fluorescent reaction, infrared inspection, penetration test, security thread, magnetic inspection, etc. During the initial setup phase, the banknote verification machine will read the relevant data information of banknotes of various denominations, and accurately detect the authenticity of banknotes and count them according to the anti-counterfeiting element layout and various detection elements of the banknotes.

Therefore, the infrared detection technology of the banknote verification machine can be used to scientifically evaluate the remaining proportion of damaged banknotes as a basis for the redemption of damaged banknotes.

One aspect of the present invention is to provide a bill roll area scanner, which includes an infrared light source, an infrared sensor, a bill feed module and an area calculation module. The infrared light source is composed of a plurality of infrared point light sources arranged in a line, wherein the infrared light source emits infrared light to scan and illuminate a bill roll to be tested passing thereunder. The infrared sensor is composed of a plurality of infrared sensors arranged in a line, wherein the infrared sensor scans and receives the infrared light reflected by the bill roll to be tested passing thereunder, and generates an infrared sensing signal. The bill feed module is used to transport the bill roll to be tested to pass under the infrared light source and the infrared sensor. The area calculation module is electrically connected to the infrared sensor. The area calculation module receives and accumulates the intensity of the infrared sensing signal from the infrared sensor to obtain an accumulated signal intensity to calculate the area of the banknote to be tested.

According to an embodiment of the present invention, the bill roll area scanner pre-scans a complete bill roll to obtain the accumulated signal strength of the infrared sensing signal of the complete bill roll as a standard signal strength.

According to an embodiment of the present invention, the area calculation module divides the accumulated signal strength of the banknote roll to be tested by the standard signal strength of the complete banknote roll to obtain the remaining area percentage of the banknote roll to be tested.

Therefore, the above-mentioned banknote roll area scanner has many advantages. The banknote roll area scanner uses scientific infrared detection technology to evaluate the remaining proportion of damaged banknotes, providing objective and accurate redemption basis for damaged banknotes; at the same time, it has an efficient area scanning function, which can quickly and accurately scan the entire banknote roll, improving work efficiency. Its standardized evaluation method ensures consistency and accuracy, while the objective evaluation method eliminates the influence of subjective factors and makes the redemption process fairer. In general, this new banknote verification machine has significant advantages in providing efficient and accurate banknote damage assessment, and can effectively improve the efficiency and fairness of redemption.

The bill feed module 130 is used to transport the bill to be tested to pass under the infrared light source 110 and the infrared sensor 120. Therefore, the dotted arrow in Figure 1 indicates that the bill is transported by the bill feed module 130 to and passes under the infrared light source 110 and the infrared sensor 120. Then, the bill to be tested is irradiated by the infrared light source 110 while reflecting the infrared light to the infrared sensor 120 to generate the infrared sensing signal.

The area calculation module 140 is electrically connected to the infrared sensor 120. The area calculation module 140 receives and accumulates the intensity of the infrared sensing signal from the infrared sensor 120, obtains an accumulated signal intensity, and then calculates the area of the banknote to be tested.

According to an embodiment of the present invention, the bill roll area scanner 100 pre-scans a complete bill roll to obtain the infrared sensing signal of the complete bill roll. Then the accumulated signal strength of the complete bill roll is used as a standard signal strength. Therefore, the area calculation module 140 can divide the accumulated signal strength of the bill roll to be tested by the standard signal strength of the complete bill roll to obtain the remaining area percentage of the bill roll to be tested, thereby completing the measurement of the remaining area of the bill roll to be tested.

Therefore, the above-mentioned new type of banknote roll area scanner has the following advantages: Scientific evaluation of damaged banknotes: Through infrared detection technology, the banknote verification machine can scientifically evaluate the remaining proportion of damaged banknotes, providing an objective and accurate evaluation method as a basis for the redemption of damaged banknotes.

Standardized evaluation: The banknote detector scans the complete banknote roll in advance to obtain the standard signal strength, and compares the accumulated signal strength of the banknote roll to be tested with it, thereby calculating the remaining area percentage of the banknote roll to be tested. This standardized evaluation method ensures the consistency and accuracy of the evaluation.

Objective evaluation: Compared with traditional methods, the evaluation method of this new type of banknote verification machine is more objective and not affected by subjective factors. Through the application of infrared technology, the degree of damage of banknotes can be evaluated more accurately, so that redemption can be carried out more fairly.

Overall, this new type of banknote area scanner has significant advantages in providing efficient and accurate banknote damage assessment, and can effectively improve the efficiency and fairness of banknote redemption.
