Concepts of human-machine automation in APCS of heavy-plate mills rolling

Abstract

Modern automated control systems can not do without the special means of organizing commu-nication with humans. The main peculiarity of human-machine interaction is the combination of formalized information processes and structures with non-formalized (as a rule, creative) in-formation processing. The latter helps not only find ways to solve complex problems that can not be found in formal models (algorithms) but also organize the process of problem solving as a holistic system. Human-machine interaction can not be fully algorithmic (in the formal sense), but it is possible to develop technology for mutual activities of humans and technical systems for problem solving. The role of people in technical control systems is constantly changing. Previously, a human was the link that was mostly responsible for process manage-ment. With the development of automated systems that was supported by the ever-increasing use of computers, people are increasingly taking over the functions of the control unit, at the same time keeping the role of an observer of the process. However, in recent years the role of humans in control systems has changed. In modern technical systems, they again play a leading role, which fully reveals their abilities and uses its boundary capabilities to optimally distribute the functions between human and machine, human and process. Human-machine interaction is a form of mutual use of reserves of humans and automated systems that is ultimately focused on humans. The article considers the stages of human-machine automation systems development, the composition and distribution of functions in human-machine systems, the possibility of their implementation, emergencies in automated technological facilities, and some examples of human-machine control in ACS TP thick-sheet rolling mills.
