THE CONCEPT OF «MODULE ARCHITECTURE» CONTROL DEVICES OF PARALLEL ACTION

Abstract

Topicality. Publications devoted to the information technology of parallel logic control, or its individual components (control devices with parallel architecture, language and technology of their programming) show that it is promising in terms of implementing control systems mainly for critical objects. At the same time, attempts to use it for general industrial sector facilities face problems of limited functionality, or rather the need to expand the functions performed, i.e., to adapt the structure of parallel-action controllers to solve specific problems. Examples of such improvements include the introduction of fuzzy inference functionality, internal timers, and counters into the structure of a classical parallel-action control automaton. Thus, the implementation of a “flexible” structure of such automata will greatly simplify the task of building parallel-action controllers with specified functionalities. The purpose of this paper is to theoretically substantiate the possibility of building a “flexible” structure of logic control automata of parallel action, to formulate the concept of “modular architecture”, and to implement the structure of a promising LCA PA in accordance with this concept. Conclusion. As a result of the research, such a disadvantage of control devices with a parallel architecture as their actual construction on the principle of “hard logic” or underutilization of the possibilities of creating “flexible” control systems based on modern FPGA crystals has been eliminated. The concept of a “modular architecture” of parallel-acting control devices is proposed, which allows creating a “flexible” structure of the corresponding logic control automata. On the basis of this concept, the structure of a modular control automaton is synthesized with the possibility of implementing a given functionality depending on the specific tasks of the control system built on its basis.
