摘要
磨浆是造纸过程中的关键工序,其目的是使纤维充分膨胀、剥离,形成适合抄造的浆料。磨浆机内部温湿度直接影响磨浆效果和能耗,传统的人工控制方式难以适应现代造纸工业的要求。本文针对磨浆机内部环境参数的特点,基于STM32单片机设计了一套远程温湿度监测控制系统。该系统采用STM32F103单片机作为控制核心,利用DHT11温湿度传感器采集磨浆机内部温湿度信号,通过MAX485实现Rs485总线与上位机的通信。上位机采用QT Creator开发,具有数据实时显示、阈值设置、故障报警等功能。系统实现了磨浆机内部温湿度的实时监测和远程控制,控制精度满足生产要求,具有一定的实用价值。
Pulping is a key process in paper-making,aimed at fully expanding and separating the fibers to create a slurry suitable for sheet formation.The internal temperature and humidity of the pulping machine directly affect the grinding strength and energy consumption,and traditional manual control methods struggle to meet the demands of modern paper manufacturing.This paper presents a remote temperature and humidity monitoring and control system for the pulping machine,designed based on the STM32 microcontroller,which focuses on the characteristics of the environment parameters inside the machine.The system uses the STM32F103 microcontroller as the control core and employs the DHT11 temperature and humidity sensor to gather internal temperature and humidity signals from the pulping machine.Communication with the host computer is achieved through MAX485 for RS485 bus connectivity.The host computer is developed using QT Creator,featuring real-time data display,threshold settings,and fault alarm functionalities.The system enables real-time monitoring and remote control of the internal temperature and humidity of the pulping machine,with a control accuracy that meets production requirements,demonstrating significant practical value.
