Shang Qing-jia · Journal of Lanzhou Jiaotong University · 2014
Expert control system based nursery greenhouse,which is core to the microcontroller of STC15F2K60S2,is designed by using technological means of topology structure of bus,GSM SMS alarm,touch screen monitoring,expert control system and remote network monitoring,etc.The design of whole system,subsystems and expert system of nursery greenhouse are described.The platform of operating and controlling is provided.Meanwhile,the data of expert system is interacted with dynamically.The environment parameters are gathered and the control instructions of monitoring platform are accepted by lower computer.As a control algorithm,the expert system intelligently controls the nursery greenhouse according to growing states of seedlings and environment parameters of greenhouses in real time and by using ideal environment parameters as control target.Some problems of intelligent control of high cost,complicated operation,difficulties of fault handling and unable to remote monitoring etc are solved by this system.
