Abstract

In modern conditions of growth of informatization, to ensure the reliability of the functioning of distributed computer information-diagnostic and control systems, which are mandatory for consideration, there are problems of assessing security and implementing protection of operational information. The state of information protection and the reliability of computer systems for corporate monitoring and diagnosis of the railway power supply system are analyzed. The main tasks in the intellectualization of component systems are defined, namely traction electric network. The principles of information protection are proposed, which include: active protection of information; convincing protection of information, consisting in the justification of the design and measures to protect the conditions and circumstances. Such a principle as the continuity of the information protection process provides for the organization of the protection of objects at all stages of the development and operation life cycle. A variety of information protection tools provides for the exclusion of patterns at the stage of selecting cover objects and various ways to implement protection, not excluding the use of standard solutions. The combination of the above principles in the work is called an integrated approach to information security, which is the basis for the creation of computer information protection systems. According to the sphere of information security, this approach complies with international ISO standards, and for the technical protection of information and state standards it complies with the requirements of existing national legislative and regulatory documents. To ensure the security of information stored and processed in computer systems, the coordinated application of various security measures is necessary.

Highlights

RESEARCH OF TRANSIENT RESPONSES INThe transient response isThe distillation process is used to separate liquid mixtures into individual components of AUTOMATIC MOBILE CONTROL SYSTEMS OF DISTILLATION PROCESS calculated sequentially, at certain time points, spaced apart by Δτ high purity
Indicators that determine the normal mode of the column: Nf=9, heat flow Qw=6.4 GJ/h, distillate flow D=62.8 kmol/h, F=229.3 kmol/h, Pf=Pj=0=Pj=18=1 atm, βx=3060.5 kmol/(m2∙h), βy=142.82 kmol/(m2∙h), feed, reflux and distillate are at boiling temperature
Transient responses are calculated using discrete mobile control actions, which consist in changing the feed point into the column (Fig. 1), and continuous, consisting in the redistribution of the feed flow between two contact devices (Fig. 2)

Rameters, their interconnection, In recent years, systems with distributed parameters have successfully used distributed, mobile [2, 3] control systems. Traditional control actions on the distillation process are intended directly to influence the material and energy balances of the column. While mobile actions suggest changes not in the intensities of the flows, but in the spatial coordinate of their entry into the apparatus. Distributed, mobile control is reduced to the choice of feed trays and selection of side products [4], the redistribution of raw materials during its two-flow feed to the column
