On the basis of the hierarchical structure of a typical cyber-physical system and main stages of crops cultivation, the list of the subsystems necessary for the creation of such a system is considered. The structures and recommendations for these systems are expounded, and the generalized structural scheme of the given cyber-physical system is described issuing from the four main objects of the research: seeding material, soil, intermediate harvest benefits, harvesting, stocking or primary processing.
The analysis of structural solutions of autonomous measuring-computing nodes (AMCN) Ethernet – oriented cyber-physical systems (CPS) have been conducted. The possibility of using the standard industrial sensors and actuators with low-speed serial ports in them have been showned. General basis of telecommunication subsystems has been given. The basic options of realization of telecommunications subsystems have been proposed and the recommendations about choosing a concrete decision by the criterion of necessary computing power for primary data processing.
Acceptance of the correct decision in the agro-production control system to great extent depends on the degree of reliability of environmental information. These issues become quite important while monitoring production which involves the products cultivation on environmentally friendly soils. Monitoring of soil parameters includes the primary state, recording of changes, their evaluation and management.
Vegetables has a number of specific properties that aremanifested in consumption, storage and processing of vegetables. The study is the formation and systematization of quality vegetable products to develop common principles for the evaluation and determination of complex quality indicator taking into account the needs of different profiles of consumers.
Approaches to the construction of conceptual models of cyber-physical systems are considered. A generalized scheme of interaction between the CPS and its environment is proposed. The set of basic CPS components is defined. The organization of CPS components functioning is considered. The corresponding conceptual model is proposed. The definition of the contour of interaction between CPS and physical processes is provided. The conceptual model of the contours of interaction is proposed. The problem of matching CPS interaction with the physical processes is considered.
The advantages and disadvantages of existing means to date of implementation environments diagnosis. A specialized diagnostic and debugging environment node corporate network. Program implemented modules that allow to quickly diagnose the problem and fix it without human intervention. Developed a clear mechanism of abnormalities in the corporate network and notifies you about your system administrator. Established database, which recorded the state of the corporate network nodes and data about them. Reached a stable operation with a simple structure and environment because of its modules.
