Abstract:In the fire detection system, the evidences of multiple sensors often conflict with each other. If the classical DS(Dempster-Shafer) evidence theory is used for information fusion, it will lead to a high rate of misjudgment. In this paper, an improved DS evidence theory algorithm based on standard deviation is proposed and applied to the fire detection system to judge the fire state.This paper first describes the working principle of the system in detail, and then uses the overall standard deviation of sensor … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
