APPARATUS AND METHOD FOR CONTROLLING A SYSTEM, SUCH AS A NUTRIENT CONTROL SYSTEM FOR FEEDING PLANTS, BASED ON ACTUAL AND PROJECTED DATA AND ACCORDING TO PREDEFINED RULES

摘要

The present invention relates to a control system for the supply of nutrients for nutrition of plants (14). An injector (18) provides a certain amount of food (12) composed of separate concentrations of specific nutrients. A conduit (10) distributes the quantity of food (12) the plants (14). A first storage memory (30) stores initial data for plants (14) fed. A computer (28) selects the volumes of specific nutrients and selects the amount of food to give to the plants (14) on the basis of the initial data in the first storage (30) and in response to this selection, controls the injector (18) that regulates the separate concentrations of specific nutrients and the amount of food (12) to provide the plants (14) as a function of selected volumes of specific nutrients and the selected amount of food (12).
