Glasshouse is appreciating a plant cultivation to produce medium essential to have of one of the facilities, different category’s appreciating flower’s request to greenhouse also doesn’t exert a homology.Computers have been used to control the environment of the glasshouse with the further development of puter. Control system is made up of central control system, terminal control equipment and sensors. A management program that contains best conditions for each growing stage should be made first. Then it should be stored in the puter memory. Computer affirms and mod the character for each glasshouse according to the management program, and then send orders to the terminal control equipment. The terminal control equipment sends test information to the central control system, and then sends control signals to make electronic mechanical equipment work
