Establishing Knowledge Base of Expert System of Mine Safety Pre-warning Based on Relational Database
Xiaosheng Liu, Qun Sun · 2008
Knowledge base is the core of expert system of mine safety pre-warning, and establishing knowledge base is a crucial work of building the expert system. The paper firstly has introduced knowledge classification and knowledge acquisition process of the expert system. Secondly, it has represented the expertise of mine safety by production rule, and then it has established the knowledge base by Microsoft SQL Sever 2000. Finally, it has inferred and judged the safety state of mine production by the control strategy combining exact and inexact reasoning based on forward and backward, which has laid a good foundation for building and realizing expert system of mine safety pre-warning ultimately.
