Research And Exploitation Of Expert System On Bridge Blasting

Since 1960s, expert system has becomes the most active field in artificial intelligence field, its application has permeated into every subject. Also, engineering design expert system has gotten extensive research and application in engineering design field.This paper applied the basic principle of expert system to demolition field, developed Intelligent System for Design of Blasting Demolition of the Bridge (ISDB) that carry out engineering design imitated the way of thinking of blasting specialist, so relieving the lack of blasting specialist and technical personnel,optimizing demolition design, raising the efficiency and level of the design.ISDB has the basic components of customary expert system: knowledge base, inference machine, Global Database, User Interface, knowledge acquisition mechanism,explain mechanism. on the knowledge representation, this system adopts the method w-hich combining formal style and frame style to describe professional field knowledge, and create knowledge base by use of Microsoft Access 2003. According to the different knowledge representation methods , correspondingly create rule base and engineering example base which be used to run general positive design and analogy design respectively. By use object oriented programming languages Microsoft VB .NET 2003 create user interface, rule-base based positive ratiocination mechanis and engineering example base based analogy ratiocination mechanism. have also unique structural feature, namely this system adopts the method of combining data base and knowledge base, so ISDB is coupled system of data base system and knowledge base system.This system consists of inputting initial parameter input,confirming blasting pattern, selecting collapse pattern, confirming blasting part, designing blasting parameter,...
