随着网络技术和信息技术的日趋成熟，自动控制系统日益采用网络和TCP/IP 协议

作为最主要的通信接口和手段．以太网作为目前应用最广泛、成长最快的局域网技术，

得到了超乎寻常的发展。而信息的获取常常需要经过高速的采集和复杂的处理得到．因

此，研究适应这种需求的技术具有很好的实用价值-As the network technology and information technology matures, increasing use of automatic control system network and TCP/IP protocol as the main communication interface and tools. Ethernet as the current most widely used, the fastest-growing local area network technology, have been extraordinary developments. And often require access to information through high-speed collection and handling of the complex. Therefore, research needs to adapt to this technology has good practical value
