The Control Strategy Of The Northern Area Greenhouse Climate Factors And The Study Of The Intelligent Control System

In northern area of China The climate is cold, and the growth period of plants is short. The greenhouse can be use as the effective way for plants to improve the survival rate and the quality of the growth. In order to raise ihe usage rate of the greenhouse, the most important way is using the control method to improve the greenhouse environment, so that it will meet the plants' growth demands. So it is necessary to study the Intelligence Greenhouse control system to fit the environmental characters of north China.Based on much of the reference, the writer analyses the trend of the Greenhouse control system in whole world, and the contre, strategy of the Intelligence Greenhouse control system is studied. Then, the intelligence greenhouse control model by using BP ANN network and the greenhouse control system are designed. And the environmental factors checking tour circuit is made. The designing of the hardware and software of the intelligence greenhouse control system is finishing.
