一种分布式SCADA系统设计与实现

摘要

Traditional SCADA is based on the copper wire construction,commonly used in small-scale data collection.With the advancement of the industry informatization,the new SCADA system is gradually evolving into one kind of IPbased and facing massive data acquisition.In this change,SCADA is facing with two problems.One of them is self-adaptive problem of IP data acquisition agreement,and the other is distributed processing problem of mass data acquisition.According to above problems,this paper,based on the soft bus technology for distributed data pipeline and secondary distributed scheduling mechanism,designed and implemented a distributed SCADA,which can be effectively applied to IP-based mass SCADA system.%传统SCADA是基于铜线构建的,一般用于小规模数据采集.随着工业信息化的进步,新型的SCADA系统正逐渐演变为基于IP的面向海量数据采集.在这样的变化中,SCADA面临两个问题:(1)IP化数据采集协议的自适应问题；(2)海量采集数据的分布式处理问题.针对上述问题,基于分布式数据管道的软总线技术和两级分布式调度机制,设计并实现了一种分布式SCADA系统,它可以有效地适用于IP化的海量SCADA系统.
