In　this　paper,　a　service-oriented　middleware　gateway　design　is　proposed,　which　sets　up　the　application　route　and　control　management　through　the　identification　of　sensors,　receives　the　data　that　send　from　perception　layer,　conducts　the　data　cleaning　and　event　analysis,　and　then　transfers　the　data　or　event　information　that　has　been　cleaned　and　filtered　to　the　upper　layers,　and　constructs　a　transparent　and　standard　model　of　conversation　between　perception　device　components.　The　underlying　device　unification　management　is　described　from　device　management,　engine　operation,　logic　engine,　event　processing　engines,　and　other　technical　aspects　in　detail,　so　as　to　when　changes　occur　in　the　sensing　devices　or　backend　database　software,　the　application　client　could　handle　the　change　without　modifying　or　do　simple　modification,　which　will　save　the　maintenance　complexity　problem　of　the　many-to-many　connection　and　solve　the　unified　standard　problem　between　numerous　products.　©　2015　Taylor　&　Francis　Group,　London.
