摘要
针对羽绒羽毛水分检测的现状,基于传热传质理论使用真空干燥的方法,研制出了一种羽绒羽毛水分快速检测仪器,该仪器使用PLC为主控制器,以触摸屏为人机交互界面,内置电子分析天平的真空罐为测量装置,实现了羽绒羽毛的水分检测;对其工作原理,硬件结构及其软件程序进行分析与设计;根据系统方案,研制出样机;使用Matlab软件做出了该样机真空干燥曲线,并对该样机的准确性、快速性、稳定性等性能做出测试;结果表明,仪器能够快速、稳定、准确地检测出羽绒羽毛的水分,同时实现自动化测量,节省大量劳动力。
A instrument for testing the moisture of the feather was designed based on the theory of the heat and mass transfer, for the current situation of the measurement of feather moisture.The main CPU of this instrument is PLC; The HMI of the instrument is touch screen;The measure device is a vacuum tank that has a electronic balance in it.This paper analyzes the principle, hardware structure and software program of the instrument.And it has developed the prototype according to the system scheme of the instrument.Using the software of Matlab software to make the vacuum drying curve and testing the performance for the prototype, such as the accuracy, quickness, stability, etc.The results suggest that the instrument can quickly,accurately and stably detect the moisture of feather,and save a lot of labor.
