银杏叶片隧道式干燥机监控系统的设计

Design of Monitoring System for Tunnel Type Dryer for Ginkgo Leaf

根据银杏叶片的干燥工艺要求,设计采用PLC与工控机对变化的温湿度进行集中控制和管理,并利用具有多段温湿度控制功能的隧道式干燥机进行加工,能够实现温湿度值的参数设置、实时显示动画、变化趋势曲线、数据库数据的查询以及报表的及时打印与输出等功能,可以使温度的控制精度达到1℃,湿度的控制精度达到5%RH。

For drying process requirement of ginkgo leaves,the design adopts PLC and industrial control to achieve centralized control and management of the change of temperature and humidity,and uses tunnel dryer that has multi-section temperature and humidity control function for processing. It can realize the parameter setting,display real-time animation of the temperature and humidity value,show trend curve,achieve database data query and report in a timely manner to print and output and other functions. The design can make the temperature controlled accurately at 1 ℃,humidity control precision in 5% RH.
