cyber-physical system

A multifunctional cyber-physical system for monitoring and testing remote computers in the WAN has been developed. This cyber-physical system has been built using microservice architecture. The system has used a website as a graphical interface, which in turn communicates with the main query separator, namely a web server. In addition, the database and the AES-256 encryption algorithm has been used to simplify data work, and to increase system security from external interventions.

A comparative analysis of existing approaches to Cyber-Physical Systems simulation has been conducted. The intrinsic peculiarities of Cyber-Physical Systems have been reasoned and generalized. Thelimitations of available simulation tools have been pointed out. The approach to Cyber-Physical Systems design solutions checking on the basis of timed automata, UPPAAL integrated tool environment and Temporal Logic of Actions usage has been proposed.

Models of information security (IS) management of cyber-physical systems (CPS) were analyzed according to ISO/IEC TR 13335 and ISO/IEC 27001, which are the basis for developing a management methodology of a complex security system (CSS) within the management model “plan – do – check – act”. The CSS management structure of CPS was proposed at the level of an information life cycle and the multilevel model “cyberspace – communication environment – physical space” based on the conception “object – threat – protection”, which extends an application of the IS management system.

The quintessence of an information security (IS) of cyber-physical systems (CPS) was presented, which is deployed on the level of complex security system (CSS) creation paradigm and conception as well as the CSS universal platform in the field “threats – profiles – tools”; it is also implemented in the part of CSS integral model of cyber-physical system “iPhone – Wi-Fi, Bluetooth – sensors” and cryptographic protection of CPS wireless communication environment based on block data encryption of algorithm “Kalyna”.

The design principles of a mobile LAN for cyber-physical systems based on microprocessors with a WI-FI wireless interface, aimed at high speed data receiving and transmission between customers, as well as the number of clients up to 16 per access point that are simultaneously connected and have the ability to transmit data are developed and investigated. In particular, the problem of switching network clients among themselves is investigated.

The problem of developing wireless sensor-actuator network as a part of the cyber-physical system is considered. The ways of implementation of the wireless connections’ scheme are analyzed. The network structure and algorithms of its operation are proposed. The results of implementation of the sensor and actuator nodes are considered.

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.

The accuracy of temperature difference meters depends on technological parameters of controlled processes. The meters of temperature difference can be constructed for operation in a wider temperature range. Their accuracy is determined by the non-identity of the sensors transformation functions.

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.
