以太网现场总线圆卡设计与实现

Ethernet Based on Fieldbus Round Card

随着以太网技术在控制领域的快速发展,基于它的智能产品不断出现。作为现场总线智能仪表设备核心的圆卡,既要起到控制的作用又要作为网络接口使用。着重介绍圆卡的设计与实现,该卡采用嵌入式微处理器作为其中央控制单元,同时配以以太网的通信控制芯片以及相应的嵌入式操作系统,构成了基于以太网的工业通信控制卡。

With the rapid developing of industrial Ethernet, smart products based on Ethernet are coming into use in industrial field level. Round communication card is one of these products, it is the heart of digital smart transducer. The paper introduces the design and achievement of the communication round card, including its architecture function and properties.
