摘要
针对木材干燥种类繁多、工艺复杂以及国内用户的实际使用环境,根据当前我国木材干燥全自动控制系统还存在着功能性单一、费时、耗能,干燥效果不理想等不足,本研究吸取当今木材干燥全自动控制系统的优势,将干燥系统各组件进行整合,运用多项有效的系统设计及触摸屏界面设计技术,结合MODBUS通讯、触摸屏和变频器等优势,实现了节能新型木材干燥智能监控系统;同时首次将材芯温度参与控制,配合干球温度、湿球温度、木材含水率等参数,形成了多参数智能控制模式。有效地提高了木材干燥的控制精度和质量,加快了木材干燥过程,节约了干燥成本,为木材干燥控制实现智能化、模块化、低碳化奠定了技术和理论基础。
Currently,there are many different kinds of wood drying methods that are complex in technical process at home,in which shortcomings exist in automatic control system,such as lack of flexibility,single function,time and energy consuming, and unsatisfactory drying effects. To solve these problems, based on the practical environment of the users at home, the authors absorbed the advantages Of current wood drying automatic control system and integrated the modules of drying system to make the new energy-saving wood drying intelligent monitoring system come true after applying multiple effective system design and touchscreen interface design measures,and combining with the advantages of the MODBUS communication, touch panel, and frequency converter. Meanwhile, the index of wood center temperature was added to this control strategy for the first time. And it constituted a multi-parameter intelligent control mode to associate with parameters of dry-bulb temperature, wet-bulb temperature and moisture content. This proposed sys- tem efficiently improved the control accuracy and quality of wood drying, accelerated the drying process, hence saved costs, and laid the technical and theoretical basis for the control of wood drying intelligent, modular, low-carbon.
