A system for Control of Temperature and Humidity in Agricultural Greenhouses
Taking the temperature and humidity demand of crops in agricultural glasshouses as the research object,re-al-time monitoring of soil water content,light intensity and indoor temperature of agricultural glasshouses is conducted to ensure the temperature and humidity demand of crops through irrigation method,shading strategy and ventilation strategy.The programmable controller(PLC)is used to set up the temperature and humidity control system,which is divided into soil moisture,light intensity and indoor temperature information acquisition,using the upper computer to analyse and process the data,and generate commands according to the control program.It is also possible to view the temperature and humid-ity situation of the agricultural greenhouse through the upper computer and at the same time adjust the temperature and humidity in the agricultural greenhouse by automatic or manual adjustment.
