Proposes and designs an intelligent embedded monitor-control network to implement the real-time monitoring for different large buildings and building groups. Aiming at the specific property of the system, multiple protocols and field bus are used to form a distributed monitor-control network based on embedded system so as to play fully the role of different protocols and field bus. Taking a high-performance micro-processor as the core, the system architecture and communication center are implemented with the multi-layer logic process. The bus protocol stack is introduced to attain the high transfer speed among protocols. An improved data communication protocol is therefore used for resolving the data loss problem of multi-host communication. The system acquires high intelligence, low cost and excellent flexibility, thus verifying that multiple protocols are useful for this system.
