摘要
提出了一种适用于小型集散控制系统(DCS)的简洁可靠的总线通信协议,核心思想是:首先针对小型集散控制系统处理数据量小、计算能力有限、实时性要求高、可靠性要求高的特点,对协议进行分析的出该协议应满足简洁性、可靠性、实时性等要求的结论,然后通过对协议简单可靠的设计(协议被设计为由物理层、数据链路层、媒体访问控制层(MAC)和应用层构成的四成协议以确保其简洁性,每层都有一定的容错策略确保其可靠性)来满足小型集散控制系统的特殊要求.
This article proposed one communication protocol construction based on minitype distributed control system(DCS), the core thought is: First against small distribution control system to deal with small amounts of data, limited computing power, real - time demanding, high-reliability characteristics required for the protocol should satisfy the concise nature, reliability, real-time requirements, such as the conclusion of the protocol and then through siniple and reliable design (the protocol consists of physical layer, data link layer and Mac layer (MAC) and the application layer to ensure its concise nature, each has a strategy to ensure its reliability ) to meet the special requirements of small distribution control system.
