The Design And Realization On The Distributed Green-House Control System

Aiming at the need of fully-automatically control of agricultural control system, the distributed intelligent greenhouse computerized control system has been researched. It is composed of center computer and SCM 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 .The whole system is composed of environment factors' inspection module,intelligent decision-making module,data processing module,database management module, irrigation control module and so on. The system owns many advantages such as intelligent decision-making, convenient operation and so on. What's more, it is easy to extend and update. This system has been realized as a product.In order to reduce the workload of program and let the computer software being reused, the system uses Component Technology. A software component is a unit of composition with contractually specified interfaces and explicit context dependencies only. A software component can be deployed independently. And it has been used to make configuration software. This thesis tells you how to make configuration software with COM.
