DCS系统在洗煤厂集控中的应用

摘要

PLC（Programmable Logic Controller） is widely used in centralized control system of coal preparation plants in recent years.The paper introduces the DCS（Distributed Control System）.After the performance and feasibility comparison of DCS and PLC,the author suggests that DCS should be promoted in the coal preparation plants.%近年来选煤厂的集中控制基本上是用PLC进行监控。文章介绍了DCS系统的,对比了DCS与PLC的性能和可靠性等特点,提出了选煤厂的集控技术应大力推广DCS系统。
