Wireless monitoring of industrial drives using internet of things technology (IOT)

Abstract

Electrical motors and drives consumes about 45% of the power generation. However, if the electrical machines are not maintained properly the drives consumes about 5% to 10 % of excess power which affects the productivity and revenue. Continuous monitoring of critical parameters of the drives is crucial for an industry which continuously operates large number of electrical drives. Before the advent of Internet of Things (IoT) technology, monitoring of the machine parameters were carried out using Supervisory Control and Data Acquisition (SCADA), which can store data temporarily, after which that data will be overwritten by more recent data. Also the online monitoring of the machine is not feasible. In the IoT technology the data collected can be safely stored in the Cloud and retrieved whenever needed. Moreover the data collected can be easy integrated through any platform to any application, which benefits the end user by cutting down huge investment costs. In the presented work, the machine parameters like current, voltage, speed and number of working hours of the machine, temperature are measured using the sensors for continuous monitoring. The data is collected and processed using microcontroller and transferred to a remote server wirelessly using Message Queuing Telemetry Transport (MQTT) protocol. The received data is then sent to the telegram server. Any deviation from the safe operating conditions is reported to the server and control room through chatbot in telegram mobile app for immediate action.
