Specifics of Implementation of Control Systems Based on Lorawan Technology

Abstract

In the context of the rapid growth of various areas of the Internet of things, there is currently no unified approach to building networks based on low-power Wide-area Network (LPWAN) wireless networks, taking into account the general requirements for them as automated control systems (ACS). There are the following areas of use of the Internet of things: industry and production; transport and transportation; control of the technical condition of building structures, air quality, background noise and energy consumption; waste management; smart Parking and providing data on traffic jams; smart street lighting and use in everyday life. Networks based on LoRaWAN technology provide low-cost energy-efficient wireless communications for modern ACS in a variety of industries. It is cost-effective for designing hardware and software for telemetry and controlling, such as a system of control and monitoring engineering systems of buildings and facilities (SMES) and automated outdoor lighting control systems. The article presents a structural and functional analysis of approaches to the construction of hardware and software complex elements based on LoRаWAN, taking into account the specifics and logic of the SMES and ASUS. It also provides calculations of network bandwidth and capacity for a single LoRaWAN gateway in a different mode of operation of ACS. A parametric analysis of existing implementations was carried out to design the management server (SU), which is the main element of the LoRaWAN network. The results allowed to obtain seventeen indicators that determine the functionality of a network server (NS). Network server software development. Major structures and the mechanisms of interaction of its elements are determined during the process of designing the original implementation of NS software.
