ABSTRACT:
A controlling and monitoring system for irrigation of localized areas of soil includes a water pipeline, a plurality of controllable irrigation valves, a plurality of field sensors measuring specific irrigation parameters, and a plurality of localized irrigation control units. Each of the control units has a sensor decoder connected to a specific one of the field sensors and a line decoder connected to a specific one of the irrigation valves. The system further includes a controller and power supply unit that applies a first alternating DC voltage signal to a two-wire cable interconnecting the controller and power supply unit and the control units. The cable provides power from the controller and power supply unit to each of the control units. The controller and power supply unit transmits schedules of instructions to the control units, and receives the irrigation parameters from the control units, through the cable.
