Design and Realization of Multi-Functional Gateway Based on SingleChip

Abstract

Abstract-Aiming at the mixed use of fieldbus in industry automatic controlling system, the paper proposes a method of multi-functional gateway based on singlechip in order to reach an inter-coordination and compatibility among different protocol standards of fieldbus. Using singlechip as the core of the system ,a proposal of inter-communication among the standard bus interfaces of CAN(Controller Area Network), Profibus(Process Fieldbus), Modbus, Serial and Bluetooth is provided. The method to resolve the incompatibility between heterogeneous fieldbus is discussed, and an integrated approach based on gateway for the interoperation between CAN and Profibus is proposed. The interface between intelligent communication chip SPC3 and singlechip is described in detail. The method can realize a unified multi-node measuring and controlling network among different fieldbus, featuring as high speed of communication, good transmission efficiency, fine working stability and low cost, which can be applied to industry controlling system of one station controlling multi-level and multi-station servomechanism.

Performance Evaluation of Network Gateway Design for NoC based System on FPGA Platform

“…The multifunctional intercommunication supported by the Gateway on a single-core chip. The different protocol standards like Bluetooth, Modbus, serial bus, Process Filed bus, and Controller area Network (CAN) provides intercommunication using gateway [4]. The intelligent Gateway has interoperation and achieves better communication among different bus networks with reconfigurability and also supports fast conversion speed, flexibility, intellectual control ability, reliability, and higher-level interface.…”
