F系列可编程控制器在煤仓配煤自控系统中的应用

Application of F Series Programming Controller in Coal Blending Auto Control System

介绍了以Ｆ系列可编程控制器（ＰＬＣ）为核心的煤仓配煤自动控制系统的组成、工作原理、主要功能及应用软件设计，并给出了该系统应用软件的自动控制子程序流程图。

Abstract According to a coal level in the coal bunk and the location of a belt conveyor, the F series programming controller with the coal blending auto control system can make an optimum coal blending process. The controller also has an improved protection function and performance dynamic display function. The coal level is measured with a coal level delay. The performance of the belt conveyor is monitored by a sensor. The coal storage signal is measured with coal storage sensors. The control system has a manual and central operation and auto control. The control board can display the location of the belt conveyor and a running direction of conveyor. According to the different operation mode of the control system, with the software and programs, an intelligent control and auto blending can be made.
