摘要
阐述了盐井选煤厂的全厂控制系统网络结构组成,介绍了DLR的工作原理,分析了DLR控制系统的优势。生产实践表明:设备级以太网环网组网方式能够减少外部元件和相关电缆,可以迅速定位故障点,缩短系统维护时间,并为将来纳入大数据奠定了技术基础。
A description is made in the paper of the structural make-up of the network of the plant＇s over-all control system, and the working principle and special advantage of the DLR control system. Practice shows that the use of the Ethernet ring networking mode can lead to reduction of the number of external components and related cables required, rapid location of point of failure, shortening of system maintenance time, and make it possible to lay a technical foundation for the incorporation of large-data in the future.
