Abstract: The research subject is the methods and means of creation of computerized process control systems of especially dangerous industrial objects (CPCS EIO). Such objects are controlled with special safety requirements, which are described in technical regulations and safety guidelines, which are obligatory for especially dangerous industrial objects. If the EIO projects undergo state expertize for compliance with such requirements and guidelines, CPCS’s compliance with them is only confirmed by the protocol between economic entities based on the testing methodology composed by them. Using he example of computer-aided engineering systems, the authors of this work develop the methodology of automation of creation of CPCS EIO, which guarantees implementation of the above mentioned safety requirements and guidelines. The scientific novelty of the study consists in, firstly, the development of a method of description of dynamic links of engineering and technical models of elements of an object, which optimize the performance of technical processes in controllers; secondly, the creation of a software and hardware complex of simulation of an object of automation, which helps realize virtual implementation of a CPCS EIO without an object to test the effectiveness of the required security facilities.

Abstract:   As a result of system research it is established that the two-level system which in real time, by means of thermal scanning and electrical measurements of the equipment and linearly - cable constructions, controls electric parameters of the electric equipment and devices (tension, current, active and jet power, including a distortion of phases and other parameters of quality of the electric power), and also temperature and electrophysical parameters of wires and cables, including leakage currents is necessary for ensuring electrical and fire safety of an industrial facility. Synthesis of system is based on methods of thermoelectric monitoring of the equipment and linear cable constructions, and well as their monitoring on alternating current. Novelty of this approach consists in the fact that the system realizes the principle of detection of pre-emergency operation of the equipment and linear cable constructions. It allows organizing timely preventive repair of the equipment and cable lines, and to reach the established GOST 12.1.004. level of fire safety.
