介绍一种由汽轮机驱动的大型高炉鼓风机用可编程控制器监控系统。采用OMRON C2000H双机系统可编程控制器,监控系统实现了原继电器线路全部监控功能,并可对系统故障按时间顺序存储,同时采用上位机联结单元将故障发生情况送到上位机,以对故障长时间记录及分析。本文着重说明了系统的工作原理、上位机联结单元的使用、故障检测程序的设计等。
A kind of programmable controller monitoring system for large blast furnace blower driven by steam turbine is introduced. Using OMRON C2000H dual-system programmable logic controller, the monitoring system to achieve the original monitoring of all the relay circuit functions, and system failures can be stored in chronological order, while the host computer link unit to the fault occurred to the host computer to fault Long record and analysis. This article focuses on the working principle of the system, the use of host computer link unit, fault detection program design.
