A fast radio telescope Ethernet node controller was developed based on embedded technology. The node controller has the Ethernet communication module,high-speed work rate and real-time reliable operation,strong computing power and remote update function. In the aspect of hardware circuitry,it has achieved Ethernet interface module,motor control circuits,network communication module circuit and clock chip circuit design. In the aspect of control programming,it has completed the design of the various program modules based on μC / OS-II. Ethernet node controller in Miyun model. By testing,it has meet the requirements of the active control system.
