摘 要：The heterogeneity of information in m ulti-sensor systems in power system makes information fusion process more difficult,and results in divarication of information fusion.Aiming at this problem,this paper presents an automatic information fusion framework.The main contribution is the method of semantic processing in information fusion.This paper describes the definition of the overall ontology,the method of mapping local information sources of sensors to the overall ontology,the subscription and publication mechanism of semantic information,and the corresponding rules for information fusion.The framework can effectively implement automatic inform ation fusion in multi-sensor systems in order to obtain more comprehensive,secure,accurate and fine-grained overall information.
