ABSTRACT:
A irrigation system for automatically irrigating an agricultural area having a plurality of fields for producing various crops includes a central station and a plurality of remote stations located in the fields. A computer with associated peripherals in the central station is loaded with an irrigation program defining a predetermined schedule for delivery of pre-established quantities of water to each field, the delivery of water can further be dependent on environmental conditions such as wind speed, temperature, humidity, and other factors. The computer via a communication path, such as a radio channel or three-wire circuit, sends coded command messages to selected remote stations for activating valves and pumps for delivering the pre-established quantities of water to the respective fields and continuously interrogates the remote stations for flow meter, water-pressure meter, environmental conditions and alarm information to diagnose proper operation and to monitor the delivery of water. The irrigation system can equally well control solid-set, pivot sprinklers, or any other suitable sprinkler systems.
