Realization of Ethernet and RS485 Communication Gateway Based on μC/OS-II System
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.
