An intelligent greenhouse remote control system based on VC++ 6.0 has been designed according to the needs of greenhouse control. The structure of this system is composed of four layers: a remote computer is taken as the client-side, a local computer is taken as the server-side, a singlechip of Stc15f2k60s2 is adopted as the greenhouse controller, a data collection unit and actuators. The environment parameters and actuators running state can be realtime displayed in the remote control software

... and the opening and closing of actuators in the greenhouse can be manual controlled by remote computer. The local computer monitoring software has the functions of real-time display, data storage, parameter settings and changings, the design of fuzzy control strategy and the status display of actuators, so as to control the environment parameters such as temperature and humidity by setting different temperature value in different period. A more than one month experiment of the system was conducted in the greenhouse, and the results show that the environment parameters such as temperature and humidity can be controlled within the proper scope of plants growth, and create a good environment for plants.
