Design of Intelligent Greenhouse Control System Based on PLC
ABSTRACT
Greenhouse provides the best growth environment for plants by improving the reliable control of plant growth environment. In this paper, an intelligent greenhouse control system based on PLC is designed. Sensors are used as data acquisition elements to collect data of greenhouse environmental factors, and PLC is used as control elements to control the operation and stop of the executing elements. The man-machine interaction interface uses Kingview software to display the situation in greenhouse through the configuration screen and eliminate the accident in time. Siemens S7-300 PLC is connected with various sensors and actuators to collect data, process and control the actuators to make corresponding control, so as to achieve the purpose of intelligent and automatic control. The application of PLC makes the greenhouse easy to install, low cost and stable.
