| 摘 要： | 针对干燥箱温湿度控制不均匀而易造成干制品品质下降、影响干燥速率等问题,分别基于单片机控制、PLC控制设计了两种温湿度自动控制系统。单片机或PLC可以实现对干燥箱中的加热元件、加湿装置及鼓风装置的自动控制,以满足物料干燥所需要求。这两种自动控制系统可以实现对干燥箱的温湿度的实时控制、智能控制,且工作可靠、反应灵敏、调试试验效果较好。该研究为减轻干燥箱在温度控制过程中存在的"热惯性"现象提供了技术参考。

| Abstract: | The reduction in dry product quality and drying rate were easy to be controlled by the temperature and humidi-ty of the dryer.Two kinds of temperature and humidity automatic control system based on single chip microcomputer con-trol and PLC were designed.Single chip microcomputer or PLC could realize the automatic control of the heating ele-ment, the humidifying device and the blower device to meet the requirements of the material drying.These could realize the real-time control and the intelligent control of the temperature and humidity, and having the characteristics of work reliability, response sensitivity and the debugging test results being better.Meanwhile, it also provided the technical ref-erence for reducing the "thermal inertia"phenomenon in the process of temperature control. |
