The focus of this project is to enhance the irrigation system for the vineyard fields while prioritizing energy efficiency. The vineyard's pumping network, connected to a local water reservoir, plays a crucial role in the irrigation process. This project designs a Controller function for the existing system. The system includes a central water reservoir that is filled overnight using water from an underground spring. When it's time for irrigation, a single pump transfers the water, which is then directed to different zones through a valve system. This setup, including the reservoir, pumps, pump motor, and piping, was already in place.
The system operates in a simple sequence: the water reservoir is refilled overnight using water from the underground spring. Throughout the next day, the system allocates the water in the reservoir to the various irrigation zones.
A crucial consideration is that there are three distinct zones that need to be irrigated, each situated at a different vertical elevation. Consequently, varying water pressures must be applied by adjusting the pump speeds to cater to these differences. A miniature operational model will be developed to systematically investigate and assess the design and sequencing of the system.
