可编程控制器在粮食干燥系统中的应用

摘要

粮食干燥工艺流程复杂，为减少人工控制，提高系统控制精度和自动化水平，构建了基于可编程控制器（programmable logic controller, PLC）的粮食干燥控制系统，编写了粮食干燥工艺控制程序，进行了控制系统测试，实验结果表明，系统运行稳定、功能强大，完全能满足粮食干燥的工艺要求。%The grain drying process is complex. In order to reduce the difficulty of control operation and enhance the automation level and control precision ,a grain drying control system by using programmable logical controller is established,and the process control program is edited. The grain drying test is carried out ,and the result shows that the control system is very stable and powerful. The system can fully meet the requirements of grain drying process.
