초록 ▼

Disclosed are a method and apparatus (10) for cataloging or dividing a given field, under irrigation by an irrigation system (100), into a plurality of zones which can be monitored for irrigation water and chemical requirements and then, delivering by way of the irrigation system, the appropriate amount of irrigation water and/or chemicals to each zone as so defined. Each of the sprinkler assemblies (105) is independently controlled by a solenoid operated valve (16), responsive to a control module (15). The control modules (15), in turn, are electronically interconnected with a data acquisition and control unit (12) which is capable of sending to the control modules (15) coded signals for either activating the sprinkler head (105) or deactivating each individual sprinkler head (105). A microprocessor (11) is provided which is programmed to determine the current position of each independent sprinkler assembly (105), to generate maps from field data or digital images, and to test for map positions which correspond to the current sprinkler positions and return the water or chemical application requirements as portrayed on the map. The microprocessor (11) then sends this information to the data acquisition and control system (12), which in turn sends these signals to the various control modules (15).

대표청구항 ▼

A method for applying variable amounts of irrigation water to a plurality of zones within a field of ground to be irrigated, using an irrigation system having a plurality of sprinkler assemblies oriented in a fixed array relative to each other, with each of said sprinkler assemblies being operable to distribute and adjust the amount of water sprinkled over a zone of ground, means for delivering water to each of the sprinkler assemblies in the fixed array, and means for moving the fixed array of sprinkler assemblies over the ground, and control means operatively connected to the plurality of sprinkler assemblies and the means for moving the fixed array, for controlling the distribution of water over the zones of ground, which comprises: inputting data, regarding selected criteria for conditions within the field into the control means; generating zone definitions and a map of the field regarding the criteria related to the spatial data; inputting data identifying the position of the sprinkler assemblies into the control means; testing map positions which correspond to the current sprinkler assembly positions for the generation of sprinkler control codes dependent upon the information portrayed on the map; generating sprinkler control codes for operating the sprinkler assemblies; transmitting control codes to individual sprinkler assemblies; and applying variable amounts of water to the area within zones according to the input data.
