Abstract

An interactive irrigation system exchanges information between an irrigation controller and a distal computer, between the irrigation controller and a user, between the user and the distal computer, and between the distal computer and a third party. The information is preferably exchanged over an Internet communication system. The exchanged information includes the following: irrigation scheduling; quantity of water applied to the landscape at the user location, which is compared to ETo values; warnings to users when potential problems with their irrigation systems are detected; and other irrigation information that is useful to the user or a third party.

Claims

1. An irrigation system comprising:

each of an irrigation controller and a water application device physically situated at a location of a user, the controller at least partially controlling the water application device; and

a communication system that sends at least one of a start time, irrigation water flow data and irrigation water pressure data from the irrigation controller to a government agency wherein the communication system comprises a public packet switched network.

2. The irrigation system of claim 1, wherein the communications system consists of bi-directional communications.

3. The irrigation system of claim 1, further comprising a microprocessor disposed in the irrigation controller, that facilitates the sending of at least one of a start time, irrigation water flow data and irrigation water pressure data from the irrigation controller to the government agency.

4. The irrigation system of claim 1, further comprising a microprocessor disposed in a unit separate from the irrigation controller, that facilitates the sending of at least one of a start time, irrigation water flow data and irrigation water pressure data from the irrigation controller to the government agency.

5. The irrigation system of claim 1, further comprising a storage device that stores data at the user location.

6. The irrigation system of claim 1 wherein the communication system comprises a two-way pager.

7. The irrigation system of claim 1 wherein the communication system comprises a web page interface.

8. A method of operating an irrigation system comprising:

physically situating each of an irrigation controller and a water application device at a location of a user;

utilizing the controller to at least partially control the water application device;

providing a first communication system comprising a public packet switched network;

coupling the irrigation controller and a government agency using the first communication system; and

sending at least one of a start time irrigation water flow data, and irrigation water pressure data from the irrigation controller to the govenment agency.

9. The method of claim 8, further comprising a step of the user entering landscape irrigation operating information into a personal computer, and the personal computer transmitting the landscape irrigation information to the irrigation controller via a second communication system.

10. The method of claim 8, further comprising:

providing the controller with a microprocessor programmed to receive additional information from a distal computer via a second communication system; and

the microprocessor determining an irrigation schedule based at least in part on landscape irrigation operating information from the user, and the additional information from the distal computer.

11. The method of claim 10, further comprising:

providing the controller with local water usage data; and

the microprocessor determining an irrigation schedule based at least in part on the water usage data.

12. The method of claim 11 wherein the step of determining an irrigation schedule further includes the microprocessor computing a desired quantity of water to be applied to a landscape at the user'"'"'s location for a specific period of time.

13. The method of claim 12 wherein the period of time is at least one day.

14. The method of claim 10 wherein the additional information from the distal computer includes weather data, and further comprising the microprocessor computing an ETo value.

16. The method of claim 8, further comprising coupling the user and a distal computer using a third communication system.

17. The method of claim 8 further comprising a microprocessor sending a warning to the user via a second communication system when an aspect of the irrigation system falls outside of a predetermined parameter.

18. The method of claim 8 further comprising a microprocessor preventing an operation of the irrigation system when the irrigation system falls outside of a predetermined parameter.

19. The method of claim 8, further comprising a step of transmitting information to a distal computer such information comprising a calculated estimate of water actually applied at a station for a time period.

20. The method of claim 19 wherein the information transmitted to the distal computer further includes a relationship between the calculated estimate of water actually applied at a station for a time period, and a computed ETo for the station for the time period.

21. The method of claim 8, further comprising sending information from a distal computer to the government agency, such information including irrigation operating information.

22. The method of claim 21, wherein the irrigation operating information includes at least one of an irrigation start time, an irrigation run time, an irrigation water flow value, and an irrigation water pressure value.

15. The method of clam 14 further comprising the microprocessor comparing the ETo value to a desired quantity of water applied to the landscape.
