一种基于温湿度检测传感器的水分控制系统

A Moisture Control System Based on Temperature and Humidity Detection Sensors

摘要: 在烟草制丝车间，物料的出口水分是影响产品质量的关键工艺参数。针对当前依赖固定初始设定值与人工经验干预的控制方式存在的鲁棒性低、适应性差问题，本文设计了一种基于温湿度前馈的智能水分控制系统。该系统通过在物料入口处安装温湿度检测传感器，实时采集环境参数，并结合生产批次信息，利用PLC控制系统从预先建立的控制系数数据库中智能匹配最佳加水量的初始值。同时，系统集成出口水分检测仪的反馈信号，构成一个以数据库查表前馈为主、PID反馈调节与微量人工干预为辅的多元控制系统。应用结果表明，该系统能有效提升出口水分的稳定性和合格率，减少人为因素的干扰。

Abstract: In the tobacco reprocessing workshop, the moisture content at the outlet of materials is a key process parameter affecting product quality. In response to the problems of low robustness and poor adaptability of the current control methods that rely on fixed initial set values and manual experience intervention, this paper designs an intelligent moisture control system based on temperature and humidity feedforward. The system installs temperature and humidity detection sensors at the material inlet to collect real-time environmental parameters, combines production batch information, and uses the PLC control system to intelligently match the initial value of the optimal water addition amount from the pre-established control coefficient database. At the same time, the system integrates the feedback signal from the outlet moisture detector to form a multi-control system that mainly uses database lookup feedforward, supplemented by PID feedback regulation and minor manual intervention. The application results show that this system can effectively improve the stability and qualification rate of the outlet moisture content, and reduce the interference from human factors.
