测控系统中的实时网络通讯研究

Research of Real-time Network Communication in Measure and Control System

针对计算机测控领域的网络通讯选择与设计问题,对比分析了TCP和UDP的特点以及现场实时通信过程传输数据的特性,提出了利用UDP灵活快速简易的特点,并且借鉴TCP实现可靠传输的一些控制机制,实现UDP基础上的数据可靠传输。

In view of choosing way of network communication and the design questions that in computer measure and control domain, analyzed the TCP and the UDP ＇characteristics as well as the transmission data characteristics that in real - time communication process eontrastively, proposed use the UDP nimble fast simple characteristic, and profited some control mechanism from the TCP to realize the reliable transmission, realized to transmit data reliably on the UDP foundation.
