Design of an Industrial Ethernet Communication Protocol Based on UDP/IP

摘要: 在供应者/消费者模式下，介绍了基于UDP/IP的UIIE网络协议的设计过程，包括数据报格式设计、数据报封装与解封、系统组态和UIIE程序设计．提出了工业以太网协议的性能评价方法，指出实时性是最重要的性能指标．通过模拟实验系统，进行了网络协议的实时性比较．实验结果表明，基于UDP/IP的UIIE网络协议比基于TCP/IP的通信协议具有更好的实时性，证明了UIIE网络协议的可行性和有效性．

Abstract: In the mode of provider/consumer,the design process of the UIIE protocol based on UDP/IP protocol is pre-sented,including datagram design,datagram encapsulation and unwrap,system configuration and UIIE program design.The performance evaluation methods of industrial Ethernet protocols are presented,in which real-time property is the most important performance.With the simulation experiment system,the realtime properties of different network protocols are compared.The experimental results indicate that the UDP/IP-based UIIE protocol is better in real-time property than the TCP/IP-based protocol,and the results also confirm the feasibility and validity of the proposed UIIE protocol.
