A WEB-SERVER-EMBEDDED ENVIRONMENTAL CONTROL SYSTEM FOR CLOSED GREENHOUSE
Low environmental control level and high energy consumption of greenhouse are bottle neck problems to restrict sustainable development of protected agriculture in China during the last decade. To solve the above problems, a web-server-embedded environmental control system for closed greenhouses was developed to improve the environmental control level and decrease the electric energy consumption. In this study, 6 demonstrated environmental control systems installed in closed greenhouses using double-layer hollow tempered glass as enclosure covering materials were evaluated for three years. Monitored performances of the environmental control system, utilizing closed loop ventilation and predictive control algorithm at middle summer and winter periods are presented.
