Description

Method and apparatus for processing bill papers and counterfeit bills at high speed {APPARATUS AND METHOD FOR HIGH SPEEDY PROCESSING A BILL}

The present invention is a bill processing apparatus for identifying the bills and counterfeit bills of the bill, by using the bill image and signal acquisition device 500 in the image and signal processing process that requires a high-speed and accurate processing process of the image and signal It provides a method and apparatus that can dramatically reduce the processing / conversion time to count and identify a large number of bills at high speed.

Banknote processing apparatus generally includes an input and output device, a transfer device, a main control device, an image acquisition device, a signal acquisition device, an image and counterfeit processing device, and the like. At this time, an important part for determining the accuracy and speed of the banknote processing apparatus is an image acquisition and conversion apparatus. Due to the nature of the bill processing apparatus, the banknote image and the signal information acquisition part are narrow, so that the entire bill image may be obtained by converting it several times, and the image processing apparatus and the signal processing apparatus are processed again. In addition, since the bills need to be simultaneously processed for various types of bills, identification of bills, authenticity, fidelity, and serial number recognition, the overall speed of the bill handling apparatus depends on how the images and signals received from each sensor are processed. Different.

As shown in FIG. 1, the bill handling process of the existing bill handling apparatus includes an image sensor 10, a thickness detection sensor 20, a magnetic sensor 30, and an optical sensor 40. Detect the signal.

In the image processing process, the image acquired by the image sensor 10 is first stored in the memory 51 in the image acquisition apparatus 51 and then transmitted to the memory 81 in the image processing apparatus 80. When one banknote image is completed, it is used in the image processing apparatus 80 to determine the roll type.

Copying the image stored in the memory 51 in the image acquisition apparatus 50 and sending it back to the memory 81 in the image processing apparatus 80 causes the image sensor 10 to acquire a bill image in a line unit. This is because the amount is so large that it cannot be stored in the memory 51 of the image acquisition apparatus 50 at all. In a bill processing apparatus that needs to acquire and process images of bills moving at high speed, a process of copying from the image acquisition apparatus 50 to the memory 81 of the image processing apparatus 80 is necessary. It becomes long and it is difficult to exceed the limit of bill processing speed. In order to shorten the processing time, the copying process may be independently performed by using a direct memory access (DMA) function. However, the image processing apparatus 80 must be continuously involved to determine when to copy the method.

Therefore, the image acquired by the image sensor 10 is sent to the memory 51 in the image acquisition apparatus 50, and when the predetermined capacity is reached, the accumulated images are sent to the image processing apparatus 80 and at the same time acquire a new image.

In addition, when the winding type is identified after the image acquisition is completed, the respective signals are acquired from the thickness detection sensor 20, the magnetic sensor 30, and the optical sensor 40 for counterfeiting and fitness processing. The acquired signal is transferred to the signal processing device 60 and stored in the memory 90 and used as data for counterfeit or thickness detection, tape detection, or the like of bills.

However, in the reality that a higher speed processing method is required, the image and signal processing method processes a single bill, which processes about 400 sheets per minute in case of serial number recognition and about 800 sheets in case of ticket recognition, thereby limiting the processing speed limit. I can't go over it.

Accordingly, an object of the present invention is to quickly and accurately process bills by transferring images and signals acquired by the existing image and signal acquisition apparatuses to the image & signal processing apparatus 600 quickly.

The present invention, in order to overcome the above problems, banknote information signal conversion unit 510 for converting the image and the signal of the banknote obtained from the sensors into a video; Signal distribution transmission unit 520 for transmitting the acquired signal to the banknote information acquisition unit 530; operating independently of the image processing device to acquire a video signal and acquires the banknote information signal consisting of one or more banknote information acquisition unit (531 ~ 534) It consists of a banknote information obtaining apparatus 500 comprising a.

By processing the image and signal faster using a separate bill information acquisition device 500 in the bill processing apparatus, it is possible to process the features such as bills and counterfeit bills, serial number recognition and fitness at a high speed. .

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

2 is an internal device diagram for a bill image and a signal processing process according to the present invention, an image sensor 100 for acquiring an image of a bill, a thickness detection sensor 200 for detecting a bill thickness and a tape, and a bill. Magnetic sensor 300 for detecting counterfeit bills by detecting buried magnetic components, optical sensor 400 for detecting counterfeit bills by detecting substances reacting to light, and converting images and signals received from the sensors into video Banknote information signal conversion unit 510, the signal distribution transmission unit 520 for transmitting the acquired video signal to the banknote information acquisition device, respectively, is operated independently from the image & signal processing device to obtain banknote information to obtain a video signal Part 530, the image & signal processing device 600 for processing the acquired video information to handle the classification of the denomination, counterfeit bills and serial number recognition, bills obtained by each device in the device It is composed of a main control unit 700 for comprehensively processing information, and a memory 800 for storing data obtained by the video acquisition unit.

An important factor that determines the speed of a banknote processing apparatus is firstly the speed of the apparatus for acquiring images and signals. This is because the minimum time required for each sensor to react is required to acquire the bill image and the signal. Second, it is time to transmit the acquired image and signal to the processing device. Lastly, it is a time required to perform various processing on the image and the signal transmitted from the image and signal processing apparatus. For the first element, continuous technological advances have resulted in the development of devices capable of acquiring images and signals in a shorter time, which can reduce time. However, processing the third element, the image, and the signal is becoming more and more time-consuming as the demand for various information processing or accuracy increases.

Accordingly, there is a need for a method of increasing the processing speed by quickly transmitting the second acquired image and signal to a processing device in image and signal processing.

In order to implement the present invention, data acquired by the image acquisition apparatus 50 is copied from the temporarily stored memory to the image processing apparatus 80, or data acquired by each sensor is processed by a separate signal processing apparatus 60. After that, instead of integrating the results, images and signals obtained from all the sensors are transmitted to the banknote information signal converter 510.

It is because a large capacity dual port memory cannot be used to store an image acquired by the image sensor 10 in the image acquisition apparatus 50 without first sending the image directly to the image processing apparatus 80. Since the image acquisition apparatus 50 must continuously acquire an image, a dual port memory such as a VRAM is required to use the data stored in the memory in the image processing apparatus 80. However, since the dual port memory is very expensive in large capacity, the dual port memory uses a small capacity as a temporary storage space between the image acquisition device 50 and the image processing device 80. Therefore, the process of copying the image acquired by the image sensor 10 to the image acquisition device 50 is necessary, and this takes a lot of time. In addition, since it is necessary to manage the process of copying the image stored in the dual port memory to the image processing apparatus 80 at high speed, it is difficult to simultaneously perform the image processing and the copy function even when using DMA.

In the present invention, each of the image sensor 100, the thickness detection sensor 200, the magnetic sensor 300, the optical sensor 400 obtains the image and the signal of the bill moving along the transport path.

First, in the case of the banknote image acquired by the image sensor 100 alternately turn on the light source required to obtain a variety of information at high speed, and obtains the corresponding light information. For example, in order to obtain a visible light image, an infrared reflection image, and an infrared transmission image of the inserted banknote, the visible light reflection, the infrared reflection, the visible light reflection, and the infrared transmission light source are sequentially turned on, and the above process is repeated to obtain an image.

Acquiring the entire image with one kind of light source is difficult to obtain various information of the banknote passing at high speed, and since the banknote is scanned at a high resolution of 200 dpi, the banknote image can be identified even if the images received at the intersection are combined. In addition, since acquiring the image information from the image sensor 100 in advance is a different part for recognizing whether the counterfeit is different and the serial number is different, the information and location of other sensors cannot be identified until the paper currency is identified using the image information. Is determined.

The images obtained from the image sensor 100 and the signals received from various sensors are converted at high speed into a video signal by the bill information signal converter 510. The signal distribution transmitter 520 transmits the bill image and the signal converted into a signal of a video format to the bill information acquisition unit 530. The video signal transmitted to the banknote information acquisition unit 530 is made into one image data according to the pre-configured image and signal information and stored in the designated memory 800 area that can be used by the image & signal processing apparatus 600.

One bill information acquisition unit 531 to 534 may receive one image or signal to be converted into a video, and the number of bill information acquisition units 531 to 534 is based on the number of images or signals to be acquired. Can be configured freely. For example, if you want to acquire the image and signal of visible light, infrared reflection, infrared transmission, ultrasound, MH, UV in the video information banknote information acquisition unit 1 visible light image, banknote information 2 infrared reflection image, banknote information 3 infrared transmission signal A total of six bill information acquisition units are required.

The image & signal processing apparatus 600 processes the received banknote image and signal to detect the classification and counterfeiting of the bill, recognize the serial number, and finally transmit it to the main controller 700.

The image sensor 100 is an image acquisition module such as CIS, CCD, CMOS, and the thickness detection sensor is a roller method and ultrasonic. In addition, the bill information acquisition unit 530 may generate a bill information signal using an FPGA or the like in some cases, and may operate independently of the image & signal processing device 600 to acquire a video signal.

3 is a flowchart illustrating a bill processing apparatus according to an embodiment of the present invention.

When the bill is inserted into the bill processing apparatus (S2), the inlet sensor senses this and the motor is operated. The bill is moved along the transport path in the bill processing apparatus and counting starts (S3). First, the image sensor 100 acquires an image of a banknote, and the thickness detection sensor 200, the magnetic sensor 300, and the optical sensor 400 acquire a signal of the banknote (S4). The images and signals acquired by the sensors are transmitted to the banknote information signal conversion unit 510 and converted into a moving image signal at high speed (S5).

The partial image and the signal converted into a video are distributed and transmitted from the banknote information acquisition unit 1 (531) to the banknote information acquisition unit N (534) by the signal distribution transmitter 520 to make one image data (S6). Each bill information acquisition unit 531 to 534 makes the received video signal into one image data (S7).

The entire bill image is generated according to the pre-configured image and signal information from the acquired image data (S8), and the generated image is compared with the data stored in the bill processing apparatus to identify the paper type and determine whether the counterfeit bill is (S9). ).

Finally, the identified banknotes are transferred to a stacker or reject stacker that is set in advance according to the kind and the counterfeit bill, and the counting ends (S10).

Therefore, converting an image and a signal into a video format and immediately sending the image and signal to the image & signal processing apparatus 600 does not require a process of copying the image information acquired from the image sensor 10 to the image processing apparatus 80 and also processes the image. The device 80 does not have to manage the copying process. In addition, even while acquiring the image information of the following bills can further secure the time to process the current bill image processing.

If the bill is processed in the above process, it is possible to process from 700 to 1600 sheets, which could count 400 sheets per minute when the serial number was recognized by the existing bill handling apparatus, and processed from 1000 to 2200 sheets from 800 sheets per minute even in winding recognition. This can provide superior processing power and speed.
