摘要
为了充分利用现有的以太网资源进行上位机与测控现场串口设备之间的数据传输,本文设计了基于ARM芯片S3C44B0X与网络芯片RTL8019AS的以太网转换接口,实现了基于UDP/IP协议的以太网通讯。实验表明,本接口具有实时性好、可靠性高的优点,满足了工业测控系统的要求。
In this paper, an Ethernet conversion interface based on ARM chip S3CA4B0X and net chip RTL8019AS is designed, which makes full use of Ethernet resource for data transfer between PC and serial port device in the test field. It realizes Ethernet communication based on UDP/IP protocol. The experiment result shows the great advantage of real time and high reliability of the interface, which satisfies the requirement in industry and control system.
