It is advisable to element that indicates whether the read code information to complete the arrow.

In more detail the physical essence of the claimed method of marking and control the length of the paper web 1 output roll 2 at a paper mill disclosed in the example of an industrial implementation of a system for implementing the method.

The system for marking and control of technological parameter paper towels is 1 and the output of the roll 2 includes: sequentially placed (along located between the input coil 9 and the output roll 2 marked control marks 3 stretch of the paper web 1) the tool 10 marks, installed with the possibility of applying patches 3 method of printing on resepectively field of the paper web 1 along the entire length of the roll 2 with a specified step 4, which (i.e. the notch 3 and step 4) are informative signs controlled process parameter (the actual length of the paper web 1 output roll 2), and unit 5 of the optical-electronic control devices and the registration of the aforementioned informative features.

Optimally, if the system includes a workstation 13 operator, which includes a keyboard 14, a monitor 15 and the printer 16, the switching associated with the computing device 8.

Figure 4 shows a block diagram of the system with respect to the installation on slitting machines, paper factories.

The system consists of the following devices:

tools 10 marks (i.e. industrial ink jet printer 17 printhead 18);

sensor 11 speed paintings 1;

unit 5 opto-electronic devices, including optical is the means 7 read (in the form of high-speed linear CCD camera) and a means 6 of the backlight;

workplace 13 operator consisting of a printer 16, a monitor 15 and the keyboard 14.

Thus, the system is designed for marking and controlling the length of the paper web 1 in the output coil 2 in paper factories, mainly, the Association Goznak. In paper factories, the system carries out the marking, control and accounting of the length of the paper web 1 roll 2 with the formation of a "passport roll".

At a paper mill (with the output winding roll 2)using the 10 marks, for example through industrial ink jet printer 17,predominantly through each meter is printing control marks 3 field marking (i.e. resepectively subsequently printed on the factory area, usually located on the edge of this blade 1) of the paper web 1 in the form of a digital code consisting, for example, of nine-digit numbers with the increment. To indicate the direction of increasing numbering next to each reference mark 3 is printed arrow. Consistently with the tool 10 marks set block 5 opto-electronic devices control, registration and accounting applied labels 3 and distances (step 4) between them. That is how between marks 3 distance (step 4) small, then resize the canvas from 1 humidity, temperature and tension winding/unwinding can be neglected and keep records of the length of the paper web 1 with great precision.

After winding roll 2 with the generated control labels 3 system in electronic and printed form forms a "passport roll"which shows the number of labels 3 and the distance between them. Next, the paper roll 2 with their own "passport roll" goes to the print factory.

The main functions of a marking system of control and accounting of the length of the paper web in the output is " a roll of 2 (installed in relation to paper mills) include the following functions:

- marking of the paper web 1 with industrial ink jet printers 17;

- read control labels 3 and distances between them in the formation of the roll 2;

- create a "passport roll" indicating the number of labels 3 and distances (step 4) between them.

The tool 10 marks characterized by the following parameters.

Type marking devices: industrial ink jet printer 17.

Marking color: black.

Properties of ink: the ink should not penetrate to the opposite side of the paper and the marking of foreign objects.

Precision marking: in increments of 1000±1 mm with reference to the field marks.

Labeling: a nine-digit number with increment and an arrow to indicate the direction of increasing values.

Optical means 7 read labels 3 and control the distances between them are based on high-speed linear CCD camera with digital output, external synchronization and linear lighting (means 6 lights), and the sensor 11 speed.

CCD-camera electronic scanning captures (with overlap) field marking with a resolution of 0.1 mm, and with the speed sensor 11 generates a mechanical scanning with a step of 0.1 mm in the direction of movement of the blade 1.

It follows from the above that this device produces continuous shooting fields of marker the Cai cloth 1 with a resolution of 0.1 mm and a speed of movement of the sheet is 1 to 10 m/s, that allows software to recognize the digital label 3 and measure the distance between them with an accuracy of 0.1 mm

The control unit, processing and display of information (electronic computing device 8) is based on an industrial computer, a specialized card video capture card and the interface card. The structural scheme of the device is presented in figure 3.

Video capture card receives the video data with a linear CCD camera, and supplies it to configure and synchronize the pulses with the interface card. And (from the received video data with a linear CCD-camera) video capture card selects the image field marking and passes on the cost of the industrial computer.

Interface card on signals from the speed sensor 11 generates a pulse synchronized with the step of 0.1 mm in the direction of movement of the blade 1 with the issuance on the capture card, it also manages the elements of the illumination means 6 in the dynamic operation.

Board industrial computer according to the image field marking carries out the detection and identification of digital labels 3 (digital codes), as well as measuring the distance between them to the nearest 0.1 mm, Except this Board industrial computer performs the setting card video capture card and the interface card, as well as service which provides working space 13 of the operator.

Software system for paper mills runs under the operating system Windows 2000XPand consists of server and client applications.

Before fabrication and testing of system hardware was simulated operation of the server and the client part of the software.

The server part of the software was simulated using the application, depicted in figure 5. Here were asked the name of the roll, the distance between the tick marks and the tolerance error of measurement.

In the end, the simulation server application were generated database labels on specific rolls, as well as by pressing the "x" were simulated ruptures of the canvas.

Using the client application were obtained from databases "passport rolls".

The server application (figure 5) is installed on industrial computer systems and performs the following functions:

- start and stop system;

- configuring system;

- monitoring the status of the system;

detection and recognition of check marks 3 and the control range (step 4) between them;

- development of a database of check marks 3 (digital codes) in the output coil 2;

- activate the alarm when violations printing control digital labels 3.

The client application can instal aromatica as on industrial computer systems, and on other computers and allows to perform the following functions:

- view the generated database patches 3 and distances between them;
