摘　　要：广东阳春新钢铁有限责任公司2#高炉自动控制系统中,通信网络采用光纤双环网结构,旨在利用光纤双环网的大容量、低损耗、高可靠性等优点为高炉生产保驾护航。文章主要介绍了光纤双环网的网络结构、具体配置及系统组成,同时也针对应用中的一些问题,通过采取修改人机界面软件数据源配置、增加供电电源、合理设置冗余管理机、根据各节点重要性及通信量连接环网等措施进行了改进,保证了光纤双环网的高可靠性,使其在高炉生产中发挥了重要作用。In order to use the large capacity, low loss, high reliability and other merits of dual-ring fiber optic net in the blast furnace production process, we adopt the dual-ring fiber optic net structure in the communication network in the 2# blast-furnace automatic control system of Guangdong Yangchun New Iron and Steel Co., Ltd. The article mainly introduces network architecture, concrete disposition and system composition of the dual-ring fiber optic net. Meanwhile, we guarantee the redundant reliability of dual-ring fiber optic net, and enable it to play an important role in the blast-furnace production by revising data source configuration of man-machine contact surface software, increasing the electric power supply, designing a reasonable redundancy management mechanism, and connecting the ring net according to the importance and traffic of various nodes.
