MQTT enabled service broker for implementation arrowhead core systems for automation of control of utility' systems

摘要

Monitoring and control of utilities networks is a challenging process due to plenty of human work, incompatibility of systems that apply a plenty of appropriate technical solutions and protocols. Thus collaboration between automation devices such as sensors, actuators, controllers, and others transformed into IoT-type of devices and systems becomes important. This research is focused on the Arrowhead Framework core systems, namely Event handler and Historian systems, its implication and role in the framework. The Event Handler system supports the handling of events, and enriches service-oriented applications with the capabilities of interacting via the publish/subscribe paradigm. We implemented the Event Handler system as a MQTT enabled service broker, and deployed Data flow programming tool Node-RED for wiring together divergent hardware devices and nodes, and APIs for online services. For implementation of the Historian System Mongo and MySQL data bases were used.
