摘　　要：以太网已经成为LAN中的主导的协议,尽管以太网的开始并不是作为测试和工业中的应用协议,但是随着网络技术的发展,以太网技术发展越来越成熟,在相当的一部分数据采集和测试测量、工业 I/O中,以太网的技术已经或者将要发挥其巨大的作用。本文简要叙述以太网的测量和数据采集系统的实现,及其独特的特点和需要特别考虑的因素。特别是以太网的的可靠性和高性能已经为测量系统带来了相当高性能的数据。Ethernet has become the mainstream of LAN protocols. With the development of the network technology, it has and will be widely used in a variety of data acquisition and measurement applications, although it was not originally developed for test and measurement system. This paper discusses the implementation of data acquisition and measurement system based on Ethernet, as well as its features. Specifically, the performance level and reliability of Ethernet is shown to be evolving to a level to deliver very high performance measurement data.
