The present invention relates to a serial number printing system and a printing method of a bill, and more particularly, to a serial number printing system and a printing method having a false number detection function when printing serial numbers.

It goes without saying that money is an integral part of modern economic life. In particular, since the transition to modern society and the scale of economic activity have increased, the importance of high-value notes rather than coins has increased.

Therefore, countries around the world are mobilizing the country's advanced papermaking and printing technology to produce bills that combine anti-counterfeiting elements and artistry, and special technologies are employed at each stage of manufacturing to prevent counterfeit. Is as follows.

First, using a cotton fiber as a raw material to produce a forgery-proof paper inserted with a hidden picture, a special material for preventing the forgery.

Next, a plate printing and intaglio printing are performed on the anti-counterfeiting paper by using a plate printing plate and an intaglio printing plate in which patterns, colors, sizes, letters, specifications, and anti-counterfeiting elements are specifically shaped. The flat plate printing is a method of printing a line and a non-drawing line, which is a generally applied printing method, to print a base pattern or a pattern of banknotes, and intaglio printing makes a line portion (concave portion) lower than a non-drawing portion of a printing plate. It is to print important parts such as design material and face value to prevent forgery.

After the flat and intaglio printing is completed, the bill is inspected in the printing state, and finally, through a letter printing process of finally printing a serial number, a seal or a signature, and completed as a single bill.

The letterpress printing, in particular serial number printing is very important as any other process because it prints the unique number of the bill, in the process of printing the serial number is missing a serial number, or a banknote given the same serial number is produced If it is on the market, there will be a problem in counterfeit money management.

Therefore, in the printing process of serial number printing by typography, it receives and stores the correct data signal for the serial number to be printed, and if the wrong number is printed, it detects it correctly and stops the printing process. The development of a printing system and a printing method having a erroneous number detection function, which can prevent the occurrence of an error, is very important.

An object of the present invention, as described above, can accurately receive the print information data generated in the process of printing the serial number of the bill by the letterpress, and has a function that can accurately and efficiently detect the printing of the wrong number To provide a serial number printing system and method thereof.

And a fifth step of writing the received signal into a log file by the monitoring computer.

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

1 is a block diagram showing each component of a bill serial number printing system having a wrong number detection function according to the present invention, Figure 2 is a printing apparatus of a bill serial number printing system having a wrong number detection function according to the present invention A schematic diagram showing the structure of a numbering drum and a sensor for detecting a wrong number, a bill serial number printing system having a wrong number detection function according to the present invention will be described with reference to FIGS.

The serial number printing system according to the present invention, as shown in Figure 1, the operating system and the application software is installed to provide an interface between the user and the system and at the same time control the computer, and the serial number printing while being controlled by the monitoring computer The device and the monitoring computer are composed of input and output cards that provide a seamless interface between the printing devices.

The monitoring computer is in the form of a general PC having a general hardware configuration, and the monitoring computer is an application for driving a general operating system, such as Windows 2000, which can provide a GUI environment, and a serial number printing apparatus to be described later. The software is installed to control the entire system as a whole, and the input / output card that provides a smooth interface between the monitoring computer and the printing apparatus includes a micro control unit (MCU), a line driver, and a decoder.

As shown in FIG. 2, the serial number printing apparatus includes a numbering drum 10 having a plurality of numberings 11 for printing a serial number of a banknote on an outer circumferential surface thereof, and on the numbering drum 10. It comprises a sensor 20 for detecting the rotational motion of the drum by irradiating the sensing wave.

Further, at one end of the outer circumferential surface of the numbering drum 10, a position mark 12 is disposed for each entry point of the number ring 11 provided on the outer circumferential surface of the numbering drum 10. FIG.

Therefore, as shown in FIG. 2, a divided area for dividing the circumference of the numbering drum 10 between any position mark 12 provided on the outer circumferential surface of the numbering drum 10 and the position mark 12 provided before and after the same. d1, d2, ..., dn) are formed.

On the other hand, the sensor 20 is located above the outer circumferential surface of the numbering drum 10 on which the position mark 12 is formed, while the numbering drum 10 rotates while one partition region dn passes thereunder. A plurality of sensed waves are irradiated onto the divided regions, and the edges of the position marks 12 are detected by the reflected waves to distinguish each divided region.

That is, when the numbering drum 10 rotates at the highest speed, the sensor has a position mark 12 formed in one division region dn and a division region dn except for the position mark 12, respectively. At least one sensing wave should be able to be irradiated.

Irradiating several sensed waves per one division as described above generally means that the printing speed, i.e., rotation of the numbering drum 10, depends on the environment (printing amount, printing time, and state of the printing apparatus) in printing a bill. That's because you have to work at different speeds. In this case, if the detection wave is irradiated only once per division area, the movement of the detection position of the division area (that is, the position of the position mark 12) by the irradiation period of the detection wave and the rotation of the numbering drum 10 is correct. Inconsistent sensor 20 does not recognize the partition correctly, so the monitoring computer cannot receive the data signal generated during the print job, or the system asks for print-related data before the print job is generated, resulting in an error in the system. Because it can be. However, in response to the change in the rotational speed of the numbering drum 10, it may be very cumbersome and almost impossible to change it from time to time by checking the relationship between the sensing wave irradiation period of the sensor 20 and the position of the position mark 12.

Hereinafter, for convenience of description, the rotation speed of the numbering suitable for the period in which the sensor 20 irradiates the sensed wave is referred to as "reference speed", and the above content will be described in more detail.

For example, when the actual rotational speed of the numbering drum 10 is very slower than the reference speed, the sensor 20 irradiates a sensing wave to the position mark 12 formed on the numbering drum 10 at least once to detect the position. The mark 12 is detected redundantly, and the monitoring computer requests a data signal for serial number printing for each detection of the sensor, regardless of whether a printing operation has been performed, so that an error occurs in the system. Done.

On the other hand, when the rotation speed of the numbering drum 10 that actually rotates is higher than the reference speed, the sensor 20 scans the sensing wave more than the speed at which the numbering drum 10 rotates to pass through one divided region. The period is delayed, and the detection of the partition is missed. Therefore, the serial number print data signal of the numbering is also missed, so that the accuracy of the serial number of the bill cannot be determined.

In this way, errors due to the detection of various types of signal missing or position marks can be generated according to the degree of deviation of the reference speed and the rotational speed of the numbering drum 10.

However, in the present invention, while the sensor 20 irradiates a plurality of sensing waves while one divided area of the numbering drum 10 passes, the area and the position mark where the position mark 12 installed in one divided area is detected. By recognizing the tolerance section a between the areas where 12 is not detected, the printing operation of the numbering 11 is recognized by extracting the edge of the position mark.

When the sensor 20 detects the edge of the position mark 12 as described above, the monitoring computer recognizes that the serial number is printed by the numbering 11, requests the serial number from the printing apparatus, and receives a signal. In this case, a log file is created using the received signal.

Therefore, the use of the apparatus of the present invention prevents an error from occurring due to the deviation of the position of the position mark 12 of the numbering drum 10, so that the rotation of the numbering drum 10 and the detection of the sensor 20 are prevented. The hassle of accurately matching the wave irradiation interval can be avoided.

3 is a flowchart showing each step in the method for printing a bill serial number having a wrong number detection function according to the present invention. Hereinafter, the method for printing a bill serial number having a wrong number detection function according to the present invention will be described with reference to FIG. Explain.

The bill serial number printing method having a wrong number detection function according to the present invention also checks the communication and the ring box between the monitoring computer, the input / output card, the printing apparatus when power is supplied to the system as usual.

Then, the setting value of the serial number to be printed in the first step is input.

In the next step, the numbering drum is aligned according to the serial number setting value input in the first step (second step).

Next, the sensor recognizes that the numbering drum is rotated by detecting the edge of the position mark while the sensor disposed on the numbering drum irradiates several sensing waves per division on the numbering drum (third). step).

The detailed process of the sensor detecting the edge of the position mark in this step is as described above.

Once the edge of the position mark is detected, numbering prints the serial number, and the monitoring computer requests and receives the data signal of the serial number printing from the numbering (step 4), and the received signal is a log file in the monitoring computer. The error in the serial number printing job can be grasped (step 5).

On the other hand, according to a preferred embodiment of the present invention, when the edge of the position mark is not detected for a predetermined period in the third step, or the print data signal of the numbering in the fourth step is not received by the monitoring computer, the serial number printing apparatus The operation can be stopped to prevent an error from occurring.

According to the bill serial number printing system and printing method having a wrong number detection function according to the present invention, since the sensor detects the edge of the position mark by scanning several sensing waves in one divided area, the rotation speed of the numbering drum is increased. As long as it can be changed according to the change, the overlapping of the partition or the omission of the partition is prevented, so that the error of the system is prevented and the monitoring computer can be provided with the signal generated when the serial number is printed correctly. Printing can be accurately detected and prevented.

The serial number printing system provided by the present invention also uses a general computer provided with a generally used GUI environment, so that when a hardware problem and a program problem occur, more rapid response is possible.
