Information security of automated control systems of technological processes

Currently, the means of measuring and converting information signals from equipment are widely used in industrial processing systems. For the most part, modern systems of mechanical processing of materials use mainly single-channel systems that work on information signals that identify the physical parameters of the technological process. Such a narrow specialization of monitoring one of the parameters usually reduces the reliability of the results obtained and, as a consequence, the reliability of the entire control system. The task of the work is to determine the possibilities of creating the foundations of the automated system on the basis of multi-channel information recording devices from processing equipment and possible approaches to the choice of criteria for the analysis of fluid information. As a result of the given analysis of a condition of branch and its modern transformations, the module of system for data collection on process (from a set of sensors) is offered for development, with a possibility of their further transformation on certain dependence, storage, transfer, and a possibility of signaling of certain events, for example, faults, for use in production automation systems and for equipment not included in the systems. At the same time, the multi-channel device of the sensor system provides opportunities to determine the full amount of information about the process. The basic modern means of control of work of technological processing CNC-equipment applied in the industry are investigated. The most perspective directions of development of multicriteria methods and automated control systems of technological equipment in the part of creation of complex sensors are determined. These sensory complexes register signals that are different in physical phenomena. The main approaches to the creation of control systems provide opportunities to build a theoretical basis given the logic of the system of obtaining specific information data in the automation of technological processes. Promising research at creating algorithms for such complex systems of quality control and diagnostics of technological processes can be aimed.

Technical Features

Abstract Modern automated control systems in industrial and private enterprises are represented by a set of programmable logic devices and components from various manufacturers. They operate based on many of the most widely used protocols and interfaces. Some manufacturers have their own solutions that are mainly focused only on their product, without direct or indirect compatibility with third-party solutions. Many control systems used now operate on relatively old solutions that cannot be partially modernized due to lack of technical resources or financial unprofitability. The paper considers the most popular industrial protocols Modbus and Profibus, analyzes their advantages, as well as features of the structure and functionality. The study of the operation problems and information security of modern control systems is considered, solutions for their elimination are analyzed. A solution for the control systems modernization was proposed based on the analysis. It can become effective and financially justified due to its technical features, allowing it to be adapted to existing solutions. Conclusions about the effectiveness of the proposed solution were formulated based on the data collected and the goals achieved.
