Long Distance, Multi-device communication with Electrical Systems through RS-485 communication

Abstract

Remote monitoring of Electrical systems in industry is crucial for safe and efficient operation of the system. If the accurate data is available, time-based analysis can be easily performed and intelligent algorithms can be applied for prediction of faults as well as need for system expansion or even maintenance. The proposed work is about development of a communication system which can help in getting accurate real-time data from multiple sensors using the RS-485 communication protocol.  The RS-485 is a multi-node sensor network that can be connected to maximum 32 sensors. The proposed work demonstrates multi-node master slave network of RS-485 by connecting different types of sensors like, temperature -humidity, pyranometer etc. The proposed work contributes towards increasing remote monitoring capabilities and collecting large spatial data for electrical systems like renewable energy system, particularly showing the robustness and adaptability of RS-485 in challenging applications.
