Abstract :
Many types of fieldbus technology are applied in power systems, because of the different bus protocol, the intelligent devices can not communicate directly in the different field bus protocols. In practical application process, a gateway between different buses is need to exchange data. This design was based on the problems of the practical application process of power system, the limitations of non-uniform for the fieldbus protocol standards. The exchange platform used of AT91RM9200 for serial, LAN, CAN expansion was completed, built internet model, the completion of several data between different bus protocol interaction. Industrial Ethernet data through interactive gateway to access, complete equipment, remote operation, monitoring, diagnostics, maintenance, resolved to some extent and the internet fieldbus interconnection and improve the control system of decentralization and openness for upgrading existing field bus network, and ultimately the business control, management of information seamless integration. Construction of the Gateway model is a good prospect and practical value.
