长输管道SCADA系统容错机制

随着我国长输管道网络的逐步建立和采用先进节能的密闭输送工艺,长输管道SCADA系统作为安全生产的保证手段,如何提高其可用性是一个重要课题。文章说明了长输管道SCADA系统现行容错机制的特点及存在问题。分析并阐述了冗余方式、故障处理方法及容错效果的内在因果关系,据此提出了改善方案。

This paper introduces SCADA system fault tolerance mechanism's characteristics and problems and put forward improved plan according to inherent relationship among redundancy mode,malfunction solved method and fault tolerance's effect.
