【摘要】 介绍冗余控制的定义和简单分类,阐明冗余控制在选矿自动控制行业的作用,并且以哈萨克斯坦尼古拉选矿厂扩产改造项目为例,介绍西门子PCS7冗余控制系统在选矿过程的应用情况,并详细介绍PCS7系统中用到的服务器冗余、处理器冗余、通信冗余、I/O冗余和电源冗余。由上述分析可知,随着技术的发展,冗余控制系统因其高可靠性,将在选矿自动化中得到广泛的应用。更多还原

【Abstract】 The paper introduces the definition of the redundancy control and simple classification, also,the effect of redundancy control in mineral auto control processing is present,with the Project of NIGULA mill scaling up production and transformation in Kazakhstan as example, The application of PCS7 redundancy control system in mineral processing is introduced, and server redundancy、processor redundancy、communication redundancy、I/O redundancy and power supply redundancy in PCS7 are also present in detail. As we can get from the analysis above,with the development of technology,redundancy control system with high reliability will have a wide application in mineral process automation field.更多还原
