| The system uses sensor technology, automatic measurement technology, communication technology and microcomputer technology to realize the monitoring and managing of the greenhouses' temperature, humidity, light intensity and CO2 density. The system consists of portable measuring instrument of greenhouse environment parameters and data synthesized management system. The kernel component of measuring instrument is an 89C51 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, and statistic of parameters' data for greenhouse environment. Through fuzzy process of real-time measuring data according to the optimal parameters, the system can provide reasonable adjusting means, and realize intelligent management of greenhouse. |
