초록 ▼

A method and apparatus for using predictive evapotranspiration (ET) and precipitation data in controlling automated and semi-automated irrigation systems. In accordance with the present invention, the conventional use of ET values is modified to take into account predicted or forecast weather events. By using forecast weather data in computing ET values, a substantial savings in water use can be achieved. Past or historical meteorological data is used to make corrective adjustments to the watering schedules that have been predicted using meteorological forecasting. That is, as each day becomes past or historical, adjustments to the overall cumulative depletion of water in the soil need to be made. When an irrigation site is to be updated with a new watering schedule, actual meteorological data is first used to correct any differences between the previously forecast and actual meteorological data to the current day. After past cumulative depletion has been determined, future predictions of precipitation and ET values are used to determine when and how much to water. Future meteorological data predictions can be updated or modified as new data becomes available, thereby allowing closer matching of predicted ET values with actual ET values. Modifying meteorological data on a daily basis results in predictions that more closely follow actual ET values than updating on a weekly or longer schedule.

대표청구항 ▼

A method for efficiently controlling irrigation, including the steps of: (a) determining evapotranspiration data characteristics of an irrigation site; (b) determining forecast meteorological data, including expected precipitation, for the irrigation site based on current meteorological conditions; (c) forecasting an ETo value, ETo′, from the forecast meteorological data; (d) calculating a current soil moisture depletion value Cdt for the irrigation site as proportional to a previous soil moisture depletion value Cdt-1 for the irrigation site plus a daily depletion value Dd that depends upon the evapotranspiration data characteristics of the irrigation site, less an effective expected precipitation value, Peff, determined from the forecast meteorological data; (e) electronically computing a watering schedule based upon at least the current soil moisture depletion value Cdt; and (f) applying the computed watering schedule to at least one irrigation control system to control at least one irrigation valve of such control system in accordance with such watering schedule, wherein the computed watering schedule controls when and how much to irrigate through each irrigation valve.
