Abstract

An electronic, microprocessor-based controller was developed and tested for automating surface irrigation systems. Communication between the central controller and individual satellite field stations is by tone telemetry over a single 3-conductor wire. The reliable Dual Tone Multiple Frequency or Touch Tone system is the same as that used in telephone communications. The system is designed to actuate momentarily energized pilot valves commonly used in automated surface irrigation systems. Because of its low power requirement, the control system can be battery-powered. It is being field tested in three different, automated surface systems.
