SPECIAL FEATURES AND PROSPECTS OF DEVELOPING ACS OF SPECIAL CHEMICAL PLANTS PROCESSES
Special features of developing APCS for modern special chemical plants are investigated in this paper. The influence of available potential hazard processes, being integral parts of these plants, on the structure of automated control systems and on the approaches to evaluate complex safety and security is shown. Most actual tendencies of developing these systems, including the problems and features of construction of intellectual and integrated ACS are presented and specified. The influence of more and more popular control intelligence on functions redistribution between generally accepted levels of classical hierarchic distributed control systems is described. The necessity of creating unique universal information platform providing the APCS integration of special chemical plant as a basis for building information automatic systems to control the enterprise is shown.
