Abstract

In the conditions of the modern economic growth, the urgency of the reliable functioning of the computer- aided system of industrial enterprises, which are critical for the Russian economy, is growing. The computer-aided fire-explosion safety systems now play a key role in the structure of computer- aided system. At the same time, they are a superfast system that can detect overpressure of explosive process units within 0.1 microseconds. In this case, it is possible to carry out a real-time pressure relief to protect the technological equipment from destruction and the personnel of the enterprise from destruction. Computer-aided fire-explosion safety systems are part of computer-aided systems of technological processes. Value of operating frequency of system bus of these systems is approximately 100 MHz. So, sustainability assessment function of information transfer channel is important scientific and technical problem. There is mathematical model of assessment of the stability of information transfer channels in the article. This model is based on scientific, theoretical and mathematical models of E. Rouse and on entropy methods of A. Wilson. Simulation was carried out of reliability of information transfer channels for various options for building these systems. It is shown that an integrated approach based on the use of a single hardware/ software platform of a microprocessor platform can be used to optimize the single of creating an ASP. Potential destabilizing effects have a negative impact on the sustainability of the work of ASIA. Under these conditions, the amount of information sharply increases in the system. And the model of estimating the entropy will allow the reliability of the automated system as a whole to depend.
