An intelligent greenhouse control system was designed to meet practical need for precision cultivation of crops.Control sys-tem sensed changes in various environmental parameters inside greenhouse through various sensors in environmental perception module.Lower computer with a microcontroller as core completes data acquisition and processing,controled execution equipment in greenhouse to complete corresponding actions,and communicated with upper computer.The upper computer software developed using LabVIEW system language realized real-time display of monitoring data,made logical judgments based on changing data and pre-set thresholds,and sended control commands to lower computer according to judgment results,achieving goal of intelligent control.
