Wireless sensor real-time control network is important construction part. With same Real-time system, this network need Real-time and reliability. Modern network mainly is Ethernet. This network speed is fast than the older, the simple protocol, the lower cost and integrate TCP/IP technique in the IT world. But because its self mechanism decide that it is a no-realtime network. This paper propose a novel wireless sensor real-time control network protocol model based on Ethernet hardware, including protocol logic, communication strategy logic, server logic, communication control logic and CMIB. At the same time, this paper introduce work flows and main function of main constructing part of this real-time protocol model.
