“…The practical application of "precision farming" was made possible due to the widespread use of electronic equipment software, the creation of remote and on-board sensors for actuating the executive automatic parts of machines and assemblies [12][13][14]. Accelerating the solution of problems to improve management in the agro-industrial complex using electronic equipment consists not only in increasing its financing, but also in training employees capable of creating and applying information technologies in agriculture, including "precision agriculture".…”

The digitalization of the agro-industrial complex is a global process, during which the traditional way of agricultural production is replaced by a new one. Information resources are being formed, the collection, synthesis and adaptation of databases, applied software products and recommendations for improving the efficiency of agricultural production are taking place. The use of digital transformation technologies in agriculture is relevant and is becoming part of a competitive business. The article describes the main trends in digital transformation in agriculture. The main trends in the use of intelligent innovations are precision farming technologies, cloud services of agricultural enterprise management, monitoring and accounting systems. The tasks and directions of digitalization of agricultural production have been defined. The research subject: relations, processes and mechanisms of digitization of agrarian sector of economy. Methods of research: analysis, synthesis, and generalization. Objective of the research: analysis of the current state of agricultural digitalization, identification of defining directions in the process of digital transformation and prospects of new technologies application in agriculture.

“…The essential difference between the ISA100.11a standard and the WirelessHART protocol is the possibility of using backbone data routing, as well as the use of individual field devices in switching mode, while WirelessHART implements the functions of transmitting and switching signals only at the field level [15]. The use of backbone routing improves the response time of autonomous field devices and reduces the load on their power supplies [11][12][13][14].…”

This article considers wireless technologies in the field of automation of technological processes and production in the energy, chemical, petrochemical and oil refining, gas, railway, mining, metallurgical and other industries where the use of wireless industrial devices is necessary due to specific features. Wireless technologies provide the ability to connect measuring devices directly to the wireless network with further transfer of information through a wireless gateway to an automated control system. This article will discuss the types of wireless networks that are classified according to the possible range of action (Wireless Wide area network, Wireless Local Area Network, Wireless Personal Area Network). The most common standards of organization of wireless industrial networks, including IEEE 802.11 b/g/n, IEEE 802.15.1, IEEE 802.15.4, IEEE 802.16 e, will also be considered, including in the field of management of chemicaltechnological processes and productions. Data transmission protocols ISA-100.11.a and WirelessHART and a number of their features will be analyzed. The basic standard network structures based on the ISA-100.11.a and WirelessHART protocols, their typical components, will be considered. The article provides an analytical comparison of the ISA100.11a and WirelessHART over the OSI network model layers, including the physical layer, the link layer, the network layer, the transport layer, the session layer, the presentation layer and the application layer (process control, management, security, application sublayer). The main stages of calculation of wireless industrial network are given, in particular: calculation of the network information load, calculation of the network's energy parameters, frequency-territorial planning, development of the communication scheme and interface with external networks. The formulas for calculating the network information load using Nazarov's methodology, calculating the network's energy parameters, taking into account the overall losses in the propagation of radio waves, including losses in free space, losses in partitions and walls inside the building, losses due to interference and signal fading are given. 2.
