Description

The utility model relates to control systems, and in particular to systems associated with obtaining information and making decisions on the management of objects based on electronic computers. The claimed technical solution can be used to evaluate information and make team decisions, as well as to manage production or other complexes and / or their structural units.

A well-known computer-based control system containing information sources with sensors located in them, information storage and processing devices, information control and transmission channels and computer terminals (certificate for PM No. 1559, class G 11 B 5/00, 1996).

The disadvantage of this device is the limited scope, in particular, inapplicability in this form to regulate the production activities of the enterprise.

A well-known production management system, consisting of a computer-based computer complex, a system of terminals associated with various databases, command devices and functional blocks of various directions. Databases and command devices include, in particular, systems tracking technological, financial, sales and other issues, as well as problems of operational management (Kafarov V.V., Dorokhov I.N. Introduction to system analysis and modeling of chemical-technological processes and systems. - M; MKHTI, 1984, pp. 5-76).

The disadvantage of this system is the use of an inflexible control system that does not allow for production adjustments in rapidly changing conditions.

Closest to the claimed solution in technical essence is an automated control system (ACS), which includes a computer complex based on several automated workstations (AWS) connected by communication channels with production and other modules, as well as subsystems for collecting information and control (certificate for PM No. 17641, class G 06 F 17/60, 2001).

The disadvantages of this system are the inapplicability for use in complex industries, for example, in the chemical industry, associated with the need to monitor a significant number of parameters in the operational mode.

The problem solved by the authors was the creation of automated control systems for enterprises in the chemical and petrochemical industries, which are characterized by the need to take into account a large number of constantly changing factors related, in particular, to the flow of various technological processes in plants operating in a wide range of temperature and other modes, with the aim of optimization of material and energy flows.

The problem was solved by creating a modified automated enterprise management system (AMS), the technical differences of which

are a computing complex consisting of a central computer (PPM) and workstation located in the production modules, as well as a subsystem for obtaining information and process control in production modules, which includes the aforementioned workstations, controllers, control sensors (CD) and shut-off and control equipment ( ZRA), moreover, the controllers are connected by communication channels to the CVC, DC and ZRA, and the AWPs are connected to the computer and ZRA.

Obtaining pulp-and-paper mill information from two sources of information increases its reliability and allows better quality control of technological processes in real time.

The scheme of the proposed control system is shown in figure 1, where the following notation is introduced:

1 - central computer (CVC),

2 - database (DB);

3 - decision making unit (BDP);

4 - production modules (PM);

5 - auxiliary modules (BCM);

6 - computer system of the auxiliary module (CS VSM);

7 - controller (K);

8 - AWP;

9 - locking and regulating equipment (ZRA);

10 - control sensors (CD);

11 - communication channels (CS).

CVC 1 is carried out on the basis of a computer and serves to receive and process information about material and energy flows of technological processes being implemented. CVK 1 is connected by feedback channels to DB 2, BPR 3, controllers of production modules K 7 and KS VSM 6.

DB 2 contains information on the parameters of technological processes, raw materials, semi-products and finished products; equipment used and

modes of operation; results of control analyzes; regulatory and other sources, etc. DB 2 is connected by a feedback channel to CVC 1.

BDP 3 is designed to evaluate the information received from CVK 1, make decisions and issue commands to the relevant structures for their execution. BDP 4 is connected by feedback channels with CVC 1, with executive structures, PM 5 and VSM 5.

PM 4 - technological installations or their complexes in which the process is carried out. PM 4 is connected by a feedback system with CVC 1, BPR 3 and VSM 5.

VSM 5 - units in which direct chemical and technological transformations are not carried out (services for providing raw materials and other resources, shipment of the finished product, analytical laboratory, etc.). VSM 5 is connected by a feedback system with CVC 1, BPR 3 and PM 4.

KS VSM 6 is a computer information system that ensures the functioning of VSM 5, including the control and accounting of material and other flows.

K 7 - a set of equipment that provides the conversion of information between primary devices (ZRA 9 and KD 10) and CVK 1.

AWP 8 is a user interface - a specialist servicing this PM 5 (for example, AWP of a chemist on duty, etc.). AWP 8 is connected by a feedback channel to CVC 1.

ZRA 9 is designed to control equipment and apparatuses of technological processes, connected by communication channels with CVC 1 through K 7.

KD 10 are designed to obtain information about the current state of the technological process, connected by communication channels with CVC 1 through K 7.

As KS 11, fiber optic communication lines are mainly used.

The inventive control system operates as follows.

Information about the parameters of the technological process is collected by the CD 10, goes to K 7, where it is converted into signals received by computers and by the CS

11 enters into the pulp and paper mill 1. In parallel, part of the technological parameters is recorded by the automated workstations 8 and also enters into the pulp and paper mill 1. In the pulp and paper mill 1, the received information is supplemented by data from the CS VSM b, is recorded in the database 2, and is also compared with the information there. During the processing of information in CVC 1, the received data are corrected in order to minimize measurement errors and obtain an updated scheme of the balances of material and energy flows. The comparison results are transferred to BDP 3 to develop a team decision to optimize the parameters of technological processes and minimize energy consumption. The command is transferred for execution through CVK 1 to K 7, AWP 8 and CS VSM 6. The command received at K 7 is converted and transmitted to the control room 9 for control action.

The use of this automated control system allows improving the reliability of regulation, reducing material and energy costs by 3-5% while ensuring the required product quality.
