Abstract:
A single-zone irrigation controller for neural networking with at least one other such single-zone or multi-zone irrigation controller, which comprises:a means for measuring at least one zonal condition;a means for setting the initial zonal threshold value for each measured zonal condition, setting the initial water threshold value, and setting the chronological duration of irrigation;a means for measuring the availability of water in a common source, said water availability measuring means being positioned upstream from a valve, headgate, or zonal pump which controls the flow of water from the source into the zone;a means for determining the chronological length of irrigation, which is connected to the duration and value setting means; anda means for directing the valve, headgate, or zonal pump which controls the flow of water from the source into the zone to open or, in the case of the zonal pump, actuate when any initial zonal threshold value has been reached and the initial water threshold value for the zone has been attained, and for directing the valve, headgate, or zonal pump which controls the flow of water from the source into the zone to close or, in the case of the zonal pump, deactuate when a chronological duration which has been set by a user or a manufacturer of the irrigation controller has transpired, which means for directing the valve, headgate, or zonal pump to open or close or to actuate or deactuate is connected to the zonal condition measuring means, the duration and value setting means, the water availability measuring means, and the means for determining the chronological length of irrigation.
