工业生产线通讯网络方案设计与分析

Design and Analysis of Communication Network Scheme for Industrial Production Lines

摘要:

针对工业以太网信息交换过程中,无线传输不安全和因系统故障导致网络通讯不稳定等问题,在分析通讯网络技术需求的基础上,完成了结构设计和网络构建,提出了更为合理的方案。基于交换机互为热备份的方式,综合利用虚拟路由器冗余协议(Virtual Router Redundancy Protocol, VRRP)和介质冗余协议(Media redundancy protocol, MRP),实现了可容忍宕机和链路失效的冗余传输通讯,提高了系统的稳定性；同时,利用快速漫游和组播监听技术并结合使用了安全模块功能,实现了数据快速无线传输并与外部网络隔离,保障了数据传输的安全性。所提出的方案在工业生产与控制领域有较好的应用前景。

Abstract:

For the problem of unsafe wireless transmission and instability of network communication in the industrial Ethernet, this paper completed the structural design and network construction based on the analysis of the related technical requirements. Based on the mutual hot backup mode, the VRRP protocol and MRP protocol are combined to realize the communication which can tolerate downtime and link failure, and improve the system stability. With iPCF, IGMP Snooping and security module functions, it realizes the fast data transmission and data security. The scheme proposed in this paper has a good application prospect in the industrial field.
