Bruno De Borba, Roberto Alexandre Dias, Fabrizio Leal Freitas . MQTT Protocol Discovery Service for an Iot-based Gensets Monitoring System. International Journal of Computer Applications. 180, 29 ( Mar 2018), 9-14. DOI=10.5120/ijca2018916695
Abstract
Condition monitoring systems designed for large power plants are too expensive to apply to small energy assets like generator sets (gensets). To enable the online monitoring of these smaller assets low cost hardware is needed, which implies limitations in processing and communication capacity. The concept of Internet of Things (IoT) and the use of communication protocols like Message Queuing Telemetry Transport (MQTT) are ideal to deal with those limitations, being a coherent alternative and economically viable to monitor low cost generation assets. Discovery Services enables devices to broadcast their available features and commands, minimizing management effort. Until now, the MQTT protocol specification does not have a standardized discovery service. This work proposes a MQTT protocol Discovery Service and its use for the provision of data collected in an IoT-based condition monitoring system for generator sets using Modbus RTU protocol over RS-485 serial bus. A prototype of the proposed system was built for testing and demonstration of the system.
