摘要
基于Windows的以太网的商业应用环境,不适合高科技领域网络通信对强实时性和高可靠性的需求。针对上述问题,研究了在嵌入式实时操作系统VxWorks的支持下,如何设计一个双网冗余备份的高可靠性网络。论述了这种网络的拓扑结构、通信协议、报文格式及其相关软件接口。实践结果表明,该网络完全满足特殊应用对象的强实时、高可靠性要求。
As common commercial application environment under Windows + Ethernet can not meet the requirements for strict real-time and high reliability of network communication in some critical engineering applications, a complete solution is provided to this problem by designing a dually redundant network with high reliability under the support of the real-time embedded operation system VxWorks. The topology structure, communication protocols, message formats, and related software interfaces of this network are described. And experiments of this network show that this design fulfils the requirements ofreal-tirne and high reliability posed by some special applications.
