Nutriculture management apparatus for smart farm by weight controll method

摘要

The present invention provides (1) a root zone environment measuring device for collecting and transmitting the data of the root zone environment; (2) a weight sensing unit for sensing the weight of the slab planted with crops to be grown; a liquid supply detection unit for sensing the amount of nutrient solution supplied to the slab; Drainage detection unit for detecting the amount of nutrient solution discharged from the slab; a display unit for displaying information about the slab; a warning unit to warn the user of the occurrence of an abnormality; Using the weight value sensed through the weight sensing unit, the amount of nutrient solution supplied through the liquid supply sensing unit, and the amount of nutrient solution detected through the drainage sensing unit, the time-dependent supply change of the nutrient solution supplied to the slab, the amount of drainage discharged from the slab The time-dependent emission change and the hourly weight change of the slab are displayed on the display unit, and when the weight change of the slab is out of a preset reference range, the warning unit warns the user of the occurrence of an abnormality, and the preset reference range is sunrise a control unit configured to be set differently for each first time period from before the first supply, a second time period from the first supply to the last supply, a third time period from the last supply to sunset, and a fourth time period from sunset to sunrise; a growth environment monitoring unit for transmitting data obtained by monitoring the growth environment of the crop to be provided to an external device through a communication network; and (3) a cloud-based server that collects and stores data in the root zone environment, analyzes data through machine learning, and performs a nutrient solution cultivation management weight control algorithm; it relates to a weight control system nutrient solution cultivation management device for smart farms, including. . According to the present invention, it is possible to provide a nutrient solution suitable for the characteristics of the work through effective monitoring for crop cultivation.
