The invention discloses a fuzzy-control-based
internet of things intelligent
irrigation and fertilization control method and
system. The method comprises the first step of data collection and
processing, wherein limiting values of the
soil humidity, nutrients and pond
water level and the
irrigation and fertilization planning time are set and stored in a
database according to the
water demand regulation and a fertilization formula of crops, and collected
soil temperature and
humidity,
soil nutrients,
air temperature and
humidity, air speed, rainfall, flow, pond
water level and
pipe network
pressure data; the second step of
intelligent control, wherein corresponding data are read from the
database and an
irrigation valve and a fertilization valve are intelligently controlled by the adoption of the
fuzzy control algorithm and a water and
fertilizer coupling mode, by comparing the current pond
water level with the set limiting value of the pond water level, starting and stopping of a water pump are intelligently controlled, and the speed of the water pump is adjusted and controlled by a PID
algorithm. The fuzzy-control-based
internet of things intelligent irrigation and fertilization control method and
system have the advantages of being good in performance, complete in function, high in expansibility, easy to operate and manage and the like, and
intelligent management and control are achieved by the adoption of fuzzy control.
