| Abstract: | At present,there are serious safety problems in the industrial control system,aiming at the shortcomings of the existing safety state evaluation model of the industrial control system.In this paper,a method of safety state evaluation of industrial control system based on BRB expert system is proposed.Firstly,the expert system of belief rule base is used to combine qualitative knowledge with quantitative monitoring data.Then ER algorithm is used for knowledge reasoning,and the initial parameters of BRB model are optimized.Finally,taking the data of a gas industry control system as an example,the experimental results show that the evaluation accuracy is higher than that of BP and SVM evaluation models. |
