In　this　paper,　we　propose　an　intelligent　building　control　system　based　on　BrowserIServer(B/S)　architecture　that　allows　intelligent　control　of　construction　equipment　and　integrate　multiple　subsystems.　The　system　is　compatible　with　three　communication　protocols　and　intellectualized　control　is　realized　by　logic　control　based　on　Event-Condition-Action(ECA)　rules.　The　system　adopts　Agilor　distributed　real-Time　database　system　to　ensure　high　real-Time　performance.　The　design　of　distributed　system　ensures　the　stability　of　system　by　ensuring　that　the　service　failure　in　a　single　area　of　system　does　not　affect　normal　operation　of　other　areas.　The　system　provides　six　kinds　of　interfaces,　which　makes　system　have　strong　integration.　The　research　of　system　architecture　provides　a　general　model　in　the　field　of　intelligent　building　for　enabling　communication　and　computing　infrastructure　for　industrial　Artificial　Intelligence(AI).　©　2019　IEEE.
