The system uses sensor technology, automatic measurement technology, communication technology and microcomputer technology to realize the monitoring and managing of the solar greenhouses' temperature, humidity, light intensity and CO2 density, and low cost measuring of CO2 density specially. It consists of portable measuring instrument of greenhouse environment parameters, data synthesized management system, expert decision-making and consultation system. The kernel component of measuring instrument is an 89C52 microprocessor, whose usage is to collect, save, and fuzzy process the environment parameters. PC communicates with measuring instrument through RS232. Through the system of data synthesized management, it realizes display, memory, query, statistic of parameters' data for greenhouse environment. Expert decision-making and consultation system can provide different stage optimal environment parameters which were needed by crops growing. Through fuzzy process of real-time measuring data according to the optimal parameters, it can provide reasonable adjusting means, and realize intelligent management of greenhouse.
