It is known that smart sensor units are one of the main components of the cyber-physical system. One of the tasks, which have been entrusted to such units, are targeting and tracking of movable objects. The algorithm of targeting on such objects using observation equipment has been considered. This algorithm is able to continuously monitor observation results, predict the direction with the highest probability of movement and form a set of commands to maximize the approximation of a moving object to the center of an information frame.
The main information parameters of the microclimate of greenhouse premises are substantiated, in particular: air temperature, relative humidity, illumination of greenhouse premises, soil temperature, soil humidity, the concentration of carbon dioxide. The cyber-physical system for vegetables’ cultivation with the regulation of temperature-humidity-insolation regime contains three subsystems, namely the subsystem of temperature control, the subsystem of humidity control, and the subsystem of insolation control.
The scientific heritage of the outstanding American scientist, the founder of cybernetics Norbert Wiener is considered in the article. The basic stages of the life path of Norbert Wiener are given. In 2019, 125 years will be celebrated since his birth and 55 years since his death. All his life, Norbert Wiener has devoted himself to scientific work at such prominent scientific centers as Harvard University, Cornell University, Columbia University, Massachusetts Institute of Technology, and other.
Ensuring an effective state policy in the field of creation and functioning of the Cyber-Physical Systems (further – CPS) in Ukraine requires a detailed study of the current state and analysis of trends in the development of CPS, their types in the world in the field of agro-industry, the peculiarities of public governance mechanisms in the leading countries of the world and especially in the EU, improvement of regulatory and legal support on CPS in Ukraine, adopting national and international standards as national, on different requirements and technical characteristics necessary for the f
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.
