双环网冗余的PLC系统在油气管道中的应用

Application of Double Ring Network Redundant PLC System in Oil and Gas Pipeline

在油气管道领域,对系统安全性、稳定性要求较高,因此,一般配置为控制器冗余、总线冗余、通信冗余。但常见的系统中,远程总线基本为单网冗余,而油气管道领域中,由于网络有一定复杂性,远程总线需要有更高的可靠性;本文基于自主环网技术,提出了一种远程总线双网环网冗余在油气管道领域的应用方案,使控制网具有极强的抗干扰能力。

In the field of oil and gas pipeline, we have high requirements for system security and stability. Therefore, it is generally configured as controller redundancy, bus redundancy and communication redundancy. But the remote bus is basically single network redundancy in common.In the field of oil and gas pipeline, the remote bus needs to be more reliable because of the complexity of the network;This paper is based on autonomous ring network technology, In this paper, we propose an application scheme of remote bus double network and ring network redundancy in oil and gas pipeline field, Make the control network have strong anti-interference ability.
