沈阳理工大学应用技术学院题 目：基于 PLC 的粮食烘干机系统设计与实现 院 系： 专 业： 班级学号： 学生姓名： 指导老师： 成 绩： 年 月 日摘 要 目前，粮食烘干技术在粮食的储存过程中起着至关重要的作用。由于人工晾晒存在各种人为因素和天气因素的限制，且存在效率低下，烘干效果不达标等问题。因此，本文介绍了一种基于 PLC 控制技术，以欧姆龙 CPM2A 可编程控制器为控制核心，对粮食烘干机的自动控制，即进粮、循环烘干、自动调温、合格粮食出粮的自动控制。实现粮食的全过程自动烘干。本文主要有硬件设计部分，软件设计部分，主程序模块，燃烧炉模块等几部分组成。软件设计在 CX-P 编程软件上以梯形图编写，主要通过步进控制指令来完成对粮食烘干机各个子过程的控制。并通过组态王软件模拟了粮食烘干机的自动控制过程。关键词：PLC；粮食烘干机；自动控制AbstractAt present,grain drying technology plays a vital role in the food storage process. Presence of a variety of human factors and weather factors limit due to the artificial drying, and there is the problem of inefficiency, the drying effect of non-compliance.Therefore, this article describes a PLC-based control technology, Omron CPM2A Programmable controller to control the core grain dryer automatic control, that is, into the grain circulation drying thermostat qualified food Payroll automaticallycontrol. The whole process of achieving food drying.In this paper, a few parts of the hardware design, software design, the main program module, and the burner module.The software is designed to ladder programming software CX-P prepared, mainly through the stepper control instructions to complete control of the various sub-processes of the grain dryer. Kingview software simulation, automatic control of grain drying process.Key words: PLC；grain dryer；automatically control目 录绪 论........................................................................................................................................
