Monitoring of Industrial Electrical Equipment using IoT

Abstract

Abstract—This article presents a monitoring system for industrial electrical equipment in a production line, aimed at the real - time monitoring of its operation state, allowing the machine management and the early detection of deviations and failures. The system performs the measurement of the effective electric current consumption of the monitored equipment, using sensors connected to a data concentrator module, which stores the collected data and performs preliminary processing before its transmission to an Internet of Things platform. The preliminary data processing focus on the analysis of the time series of the electric current values in order to detect the state of operation of the monitored machine. Then, this information is sent via the Internet to an IoT platform for long-term storage, post-processing and real-time data visualization by the end-users. When a behavior deviation is detected in the current consumption, related to some type of potential failure, the system issues alerts and sends additional information to the production line supervisor, for example, to proceed to maintenance intervention in the equipment, without production impact. The availability of the full time data series, as well as the history of all occurrences recorded by the monitoring system also allows for the search of correlations with data from other sources, and its interpretation in contexts beyond machine operation or maintenance. The proposed monitoring system provides minimum automation in old machines and opens up the possibility of independent, parallel and non-intrusive monitoring in machines that already have supervisory systems.
