Abstract:

Currently, algorithms and methods for monitoring complex systems of functioning of military equipment of block structure are widely represented in scientific literature, but very little attention has been paid to the practical application of the described algorithms and methods. The improvement and development of new models of military equipment of a modular structure, prescribes control over the functioning of products at all stages of manufacture and stages of operation. For military hardware products of block structure, there are several stages of functioning control, depending on their configuration (a separate block, assembly of several blocks into a product, a fully assembled BT product). This article analyzes a common technique for solving the problem of control of discrete communication lines by sequential «transfer» of the logic-time diagram of control of discrete links into the program code. Existing approaches to solving this problem have a number of drawbacks and require the practical development and improvement of existing scientific methods and models using a synchronous Mealy machine and a transition graph describing the interaction of a military hardware product system of a block structure with external control systems at key clock moments. Based on the analysis of the features of real systems of military equipment of block structure in the control mode, a description is presented using an asynchronous finite automaton with memory, while it should be borne in mind that mathematical modeling of the operation of an automaton of this class is an extremely difficult task. To simplify mathematical expressions, it is necessary to switch from an asynchronous finite state machine with memory to the classical synchronous Mealy automaton, while it should be borne in mind that the main advantage of using the Mealy automaton is the possibility of the automaton's reaction during the current cycle, which is due to the dependence of the cur-rent output combination on the current input combination. The use of the Mealy automaton causes the transition from continuous time to discrete time. The use of the classic synchronous Mealy automaton will simplify the complexity of the task of constructing mathematical models of discrete communication lines for military equipment of a block structure and will provide a low entry thresh-old for specialists in the field of creating control systems, and will also have greater clarity. The proposed comprehensive approach to monitoring the functioning of a military equipment product of a modular structure at the stage of prototyping and testing, as well as at the operational stage, will significantly improve the quality of manufactured military equipment and can be used in the develop-ment or improvement of existing models of military equipment.
