Agricultural complexes, including agriculture, are a good environment for the introduction of modern technologies and methods of using unmanned aerial vehicles to solve various tasks. Currently, in distributed control systems in various agricultural complexes using unmanned aerial vehicles, the classical hardware and software architecture for building such systems has been established. However, this approach has a number of significant drawbacks. (Research purpose) The research purpose is selecting the IIoT of the wireless real-time communication protocol of unmanned aerial vehicles for irrigation of agricultural complexes with a ground-based industrial system and developing concepts of a hardware and software complex 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 these topics, as source data and materials for the analysis and design of the proposed hardware architecture of the IIoT platform. The method of decomposition according to automation levels was applied; the method of decomposition according to the 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 the hardware and software structure in the form of schematic diagrams. (Results and discussions) Proposed the concept of information data transmission based on the IIoT protocol of DDS-real-time data transmission. (Conclusions) It has been shown that classical architectural approaches to data transmission in the conditions of wireless systems and agro-unmanned aircraft have proven themselves well, however, the need to introduce new architectural and software methods and protocols for data transmission in real time leads to the need to study promising ways to implement this functionality. We analyzed the existing global trends in the field under consideration and proposed an up-to-date and up-to-date concept of IIoT architecture of distributed data transmission systems within the framework of a distributed management and monitoring system for agricultural complexes based on unmanned aircraft.
