Greenhouse Environment Control and Monitoring System in the Hilly Area of Chongqing

The control and monitoring system of a greenhouse is a multi-input multi-output system. By considering the local nature, climate and geography characteristics of Chongqing, a control scheme and its topology for the control and monitoring system were presented in the paper. The optimal environment was obtained through cooperation of different actuating devices based on certain control strategy and algorithm. The reliability performance of the system was improved by the redundant design. Practical application and operation show that the control and monitoring system meets all requirements for the greenhouse in the hilly land area in Chongqing.
