In order to realize the interconnection between RS485 interface equipments and industrial Ethernet to satisfy the information integration needs from enterprise equipment control layer to management layer, the paper introduces a realizing method of embedded Ethernet gateway based on μC/OS-II system. This method use LM3S8962 micro-controller which integrate Ethernet controller as control core to finish the conversion between Modbus and TCP/IP protocol by opening up a data buffer, and to enhance the speed of data communication. Compared with other embedded gateway it has simple hardware structure, easy software and strong anti-interference, etc.
