Distributed control system of solar domestic hot water heating using open-source

Abstract

This paper deals with the use of open-source software for distributed control system of solar domestic hot water heating. It presents the hydraulic circuit of solar collectors with autonomously safe drain-back system and control components of our own design. Further are described used modules, communication protocol and the use of the control computer. Implementation of open-source software uses the Python programming language and SCADA/HMI solution pvbrowser. Using the collected operational data necessary for the improvement of the mathematical model will greatly simplify debugging similar systems in practice. © Springer International Publishing Switzerland 2014.
