Abstract


Food production and food security is a direct impact on the sustainable development of agriculture and people's living standards . Maize is the major food crops , corn insect pest prevention and diagnosis of Jilin Province has been a hotspot of agricultural science and technology research . This article is for the current production status of Jilin Province , the main agricultural production knowledge , computer visualization technology developed by a well-established corn insect pest diagnosis expert system . This system has been designed to follow the life cycle of the software engineering method . Concrete realization of a phased design , development , structured analysis method presented a summary of the entire system design and programs , and then gradually in-depth study in accordance with the design idea . The realization process of the system is to look first at home and abroad and at the same time face-to-face exchanges with domestic authoritative experts to ask them to analyze the current period and incidence of insect pests of corn law , to collect, aggregate and summarize data and information obtained , and then data flow analysis , the proposed subsystem functional structure table , the last use of the visual language Delphi 6.0 , Microsoft ACCESS2003 database and multimedia technology tools such as corn diseases and pests expert system based on the framework of said . In the process of the establishment of the system , designed according to the needs of the four functional modules , they are diagnostic module , query module , the basic data maintenance module and pests production the relationship module system management . Traditional expert systems knowledge acquisition \maize pests diagnosis expert system based on the framework represented for the imitation of experts in the field of thinking , to supplement or replace the agricultural expert guidance corn production . This article focuses on the overall structure of the system , knowledge representation , inference mechanism and system applications .
