Sep 27, 2002

Appl. No.:

10/259370

Inventors:

Michael Marian - Penngrove CA, US

Assignee:

Hydropoint Data Systems, Inc. - San Francisco CA

International Classification:

A01G 27/00

US Classification:

239 69

Abstract:

A system for providing reliable communications between components of an irrigation system is provided. The system includes a central control, a number of communication systems each representing a transmission channel, an irrigation controller having a receiver that is configured to receive signals from the communication systems, and one or more valves controlled by the irrigation controller to provide irrigation. According to one aspect of the system, in order to direct the irrigation controller to take certain actions, the central control first generates a message. The message is then delivered to the communication systems. In one instance, the message is transmitted by the communication systems in a rotating manner, i. e. , the communication systems take turn in transmitting the message in a predetermined cycle. To ensure proper reception of the message, the irrigation controller conforms to the rotational transmission schedule of the communication systems and monitors the incoming signals accordingly.

Abstract:

A system for providing irrigation control is provided. The system includes a number of non-local data sources for providing data, a processor and an irrigation system. The processor is configured to receive data from one or more of the non-local data sources and calculate an evapotranspiration (ET) value for an irrigation area that is non-local with respect to the non-local data sources. The processor is further configured to create or alter an irrigation program based on the ET value. The irrigation system is configured to receive the irrigation program from the processor and provide appropriate irrigation control for the irrigation area using the irrigation program.

International Classification:

G05D 7/00

US Classification:

700284, 239 63, 239 69, 137 782

Abstract:

A system for providing irrigation control is provided. The system includes a processor configured to calculate an offset to an evapotranspiration (ET) value and an irrigation system configured to receive the offset from the processor and provide appropriate irrigation adjustment based on the offset. The offset is calculated based on the ET value and the ET value has been previously provided to the irrigation system.

Appl. No.:

7/763001

Inventors:

Michael B. Marian - Petaluma CA

International Classification:

H04K 102
A01G 2516

US Classification:

380 9

Abstract:

The invention bypasses a need for human participation in the process of remotely controlling irrigation sprinklers using Evapotranspiration (ET) values. In one embodiment, a transmitter broadcasts updated Evapotranspiration (ET) data directly to a collection of receiver/controller units using an FM subcarrier. These receiver/controller units are microprocessor-based and coupled to a set of irrigation sprinklers. The method provides for broadcasting an encoded ET data signal to a collection of receiving and irrigation-controlling units. The receiving and irrigation-controlling units include microprocessor means and storage means for storing a preset ET zone reference and crop adjustment values. The method also includes receiving and decrypting an encrypted ET data signal into a broadcast ET zone identifier and a broadcast corresponding ET value. The method further compares the broadcast ET zone identifier with the preset ET zone reference.
