Abstract
This article considers the project development of a wireless data network organization in the educational laboratory complex «Yokogawa» of the CA&IT Institute, intended for carrying out practical and laboratory classes with students of specialized specialties of the institute and students of the FAS. Wireless technologies provide the ability to connect measuring devices directly to a wireless network with further transfer of information through a wireless gateway to an automated control system. This article discusses the capabilities of the wireless field system. A generalized three-level block diagram of automation complex equipment of a laboratory complex based on wireless equipment is given. The selection of wireless equipment for the implementation of the automation system of the laboratory complex based on the standard ISA 100.11a was carried out. The basic stages of computing the 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 information load of the network was calculated using the Nazarov method, the energy parameters of the network were calculated taking into account the total losses during propagation of radio waves, including losses in free space, losses in partitions and walls inside the building, losses due to interference and signal fading.
Keywords: automation, wireless networks, energy and information network parameters, network protocol, data transmission, computer networks, data processing, data transmission networks, the principle of creating computer networks.
