我国是一个人口大国，也是一个农业大国，我国的粮食总产量近年大约平均有5亿吨，每年收获的粮食有20％属高水分。因此研究一种自动化程度高，烘后粮食品质好，性能稳定的谷物干燥机已经迫在眉睫。随着计算机技术的飞速发展，把计算机技术应用到谷物干燥机上是可行的，是大势所趋。
本系统就是针对粮干机控制系统而设计的。利用WinCC V6.0组态软件设计监控画面。粮干机系统监控画面主要由净化画面、玉米输送画面、烘干塔画面、热风机组画面、蒸汽冷凝水画面组成。可以实现对烘箱内部各温控点的实时采集与显示并根据生产工艺要求设定温控点的温度，从而改变热风机出风大小，保证对干燥塔的温度控制。WinCC的图形系统可处理运行中在屏幕上的所有输入和输出，可使用WinCC图形设计器来生成用于粮干机系统可视化和操作的图形，应用报警记录提供的显示和操作选项来获取和归档结果，从而可以对下位机（PLC）进行时事监控。

Our country is a populous country as well as an agricultural one.In recent years,our average annual total grain output is about five hundred million tons,20% of which have high moisture content.Thus,devising a highly automatic grain dryer that produces good quality grain after baking and has stable performance is an urgent task.With the rapid development of computer technology,it is feasible and relevant with the time to apply computer technology to grain dryer.

This system is designed specifically for the monitoring system of grain dryer.WinCC V6.0 configuration software is used to design the monitoring graphics.The monitoring graphics of grain dryer monitoring system includes the purification plane,the corn transfer plane,the grain dryer plane,the air heater plane,and the condensate water plane. It can collect and display real-time temperature at each temperature-control point inside the dryer.It can also set the temperature at the temperature-control points according
