Bovchaliuk S. Models, methods and means of information technology of parallel logic control of automatic railway machinery objects

The object of a research is the processes of logic control of automatic railway machinery objects. The target of a study is increase the speed of operation and reliability of realizing logic control functions of automatic railway machinery objects. The basic methods of the research are elements of abstract algebra, eventual automata theory, matrix theory - at development of mathematical model and synthesis of the LCA PA structure, theory of the parallel programming - at development of universal algorithm of the LCA PA functioning, imitation design - at research, testing and verification of information technology of parallel logic control elements, theory of reliability - at implementation of comparative estimation of dependable descriptions of classic and offered information technologies of logical control. Scientific value of results is determined in the development of the methods of construction of automatons and information technologies, including methods of software construction. Practical values consists of taking of theoretical positions of dissertation to the concrete engineering methods, designer developments, recommendations, tools and their direct use at creation of the control systems of automatic railway machinery objects. The simulator of a logic control automaton of parallel action has first been devised which in contrast to the famous automatons is controlled with a flow of input conditions allowing to increase the speed of operation and reliability of realizing logic control functions. There has been improved programming method of parallel logic control algorithms which provides automatic transmission of the devised technological language into the programming language of CPLD-controllers and allows to decrease the number of possible errors while developing control programs. There has been further developed the estimation method of information technologies allowing to compare the created technology with traditional ones and to determine the field of rational application of information technologies of parallel logic control. The further use of the dissertation results is recommended in a research, project and production organizations taking part in development and implementation of projects of development and progress of the control systems of automatic railway machinery objects.
