For the effective development of agricultural complexes, the introduction of a variety of advanced technologies, including unmanned aerial vehicles, is especially important. In the distributed control systems used in various agricultural complexes and logging industries using unmanned aerial vehicles, the classical hardware and software architecture for creating such systems has been established. However, this approach has a number of significant drawbacks, in particular, the presence of a large number of different data bus standards at different levels of the platform architecture, which quite often significantly complicates the integration of individual parts of the system. The lack of a single standard within the software protocol for real-time data transmission leads to data fragmentation at all levels of the system as a whole. (Research Purpose) The research purpose is developing the concept of a hardware and software architecture for transmitting information data based on the Data Distribution Service protocol in real time as part of monitoring, managing and distributing tasks between unmanned aerial vehicles, as well as at all levels of a distributed agroforestry system using modern technologies and practices of the industrial Internet of Things. (Materials and methods) Used open sources of international communities in the field of automation and the industrial Internet of Things, as well as domestic and foreign scientific publications on this subject. The method of decomposition by automation levels was applied; the method of decomposition by functionality performed by individual hardware and software components of the system; the method of summarizing information from modern sources on the subject of research; formalization of hardware and software structures in the form of schematic diagrams. (Results and discussion) We have developed a concept for transmitting information data based on the Industrial Internet of Things Data Distribution Service protocol to ensure real-time data transmission. The proposed system makes it possible to implement unified information flows for monitoring and controlling unmanned aerial vehicles at all levels of a distributed agroforestry system. This helps simplify the integration of unmanned aerial systems into agroforestry systems of various orientation and complexity, eliminating difficulties in the interaction of various system components at all levels, including cloud solutions and other Industrial Internet of Things platforms. (Conclusions) As a result of the study, the problems of integrating the information flows of the agroforestry system and data transmission at its various levels were identified. It is proposed to use the Data Distribution Service data transfer protocol as a single standard at all levels of the system, which in the future will ensure compatibility and ease of integration of unmanned aerial vehicles of various manufacturers within a single system.
