RS 485总线与CAN总线应用比较

Comparing the Application of Bus RS 485 With that of Bus CAN

作为在工业自动化领域应用日益广泛的RS 485总线与CAN总线,由于结构简单、应用方便而成为许多网络拓扑结构的应用总线。从RS 485总线、CAN总线的通信机理与网络性能来比较他们应用的不同。

Bus RS 485 and Bus CAN,which are increasingly applied in the field of industrial automation,have become the application bus of many structures of network topology because of their simple structure and convenient application.This paper compares the differences in their respective application in terms of the communication mechanism and network performance of Bus RS 485 and Bus CAN.
