Abstract
Cultivating support system is designed and examined based on the CICS (Computer Integrated Cultivation System), system of which has the computer network composed of both usual micro-computer for environmental control of crops and the special computer for the artificial intelligence. In the system, four sub-systems are prepared; these are“LAN”, “Identification and Control”, “Expert System”and“Agricultural Strategies”.“LAN”and“Identification and Control”are usually engineering problem. On the contrary, “Expert System”is more biological and use of AT computer is inevitable. Whole cultivating process of the crop is supported by these sub-systems. In the important stage through the whole cultivating term, the status of the crop is able to be discriminated based on the AT computer. Thus the adequate set-point of the environmental control could be decided based on the status of the crop. Finally, the sub-system for“Agricultural Strategies”is expected as CIM in agriculture, in other words, as the high-level decision from the point of management view. In this paper, the tomato cultivating support system is discussed, where an expert system is designed for the adjustment of EC'set-point in the NFT. As the results, it seems evident that the expert system may be reasonable and that CICS proposed in this paper should be the most reasonable system.
