Nowadays,　the　intelligent　building　integration　system　includes　different　subsystems.　Different　subsystems　use　different　communication　protocols.　Due　to　different　types　of　intelligent　devices　in　the　same　subsystem,　the　communication　protocols　used　are　also　different,　such　as　Modbus　/　TCP　protocol,　BACnet　/　IP　protocol　and　various　private　protocols.　Faced　with　the　parsing　of　many　kinds　of　communication　protocols,　if　we　write　the　parsing　software　for　each　protocol　separately,　the　workload　is　large　and　the　later　maintenance　is　complex.　Therefore,　without　the　need　to　write　a　separate　parsing　program　for　each　protocol,　how　to　analyze　multiple　communication　protocols　is　still　an　issue　for　intelligent　building　integration　systems.　Aiming　at　this　problem,　this　paper　combines　database　technology　and　protocol　parsing　technology,　and　uses　the　TCP　protocol-based　Socket　technology　to　achieve　mutual　communication　between　networks.　In　this　paper,　a　multi-protocol　parsing　and　configuration　system　is　proposed.　A　general-purpose　protocol　parsing　component　is　designed　to　parse　the　received　data　packets　according　to　the　protocol　data　format　configured　in　the　database.
