The Intelligent Greenhouse Computerized Control System is a part of the National "863" Program, Application and Demonstration of Equipment Agriculture Digitization Technology. The goal is realize special crop and low investment, high profit and high efficiency using the advanced control method and realize application and spread of intelligent environment integration control system through combining plenty of data obtained and practice.Equipment agriculture is a burgeoning industry, which can make full use of resource and have high-level of automation. It is technique and intelligence concentrated and can bring appreciation profit. Modern automatic control greenhouse is one of the realization forms of facility agriculture, which can make a man-made climate of the greenhouse or eliminate the disadvantages for crop. In such a greenhouse, the produce period of crop can be shortened. Meanwhile the aim of high-quality, high-output, high-benefit can be reached.The Intelligent Greenhouse Computerized Control System is composed of center computer and PLC as its control core. Based on artificial intelligence and expert system knowledge database, the greenhouse 's environment factors will be adjusted in time with the help of real-time inspection and intelligent decision-making module. Furthermore, optimized growing conditions of crops will be created.Because of complexity and variability of the field, the traditional control method is difficult to realize the precise control. So the climate control based on fuzzy control is presented. The hardware of the system is composed of environment factors' inspection module and control implementation module. The software of the system is composed of database management module, artificial control module, system parameter setting module, intelligent decision-making module, data processing module, control implementation module, help file module and so on. The system owns many advantages such as intelligent decision-making, convenient operation, high reliability, being easy to extend and update and so on. This system has been applied into Yantai Qingye Garden Co., Ltd and obtained good effect.
