Using Elixir and Nerves for Small Hydroelectric Power Control

The presentation highlights the active Nerves community in Japan and discusses using Elixir in industrial applications, particularly in controlling small hydroelectric power plants. It covers the control system's overview and the system architecture with Nerves. The first part addresses the overall approach, while the second part dives into the technical design and challenges of building distributed control systems for these plants. Key topics include the formation of an Erlang cluster, the development of a custom Modbus communication library called 'Modbuzz', and handling safety considerations, such as fault monitoring and failure strategies. Additionally, it explains preparations for on-site troubleshooting with tools like Mox and mix upload.hotswap, providing practical insights for engineers interested in deploying Nerves in production-critical environments.
