摘要
在造纸工业智能化不断推进的背景下,纸张质量在线监测及缺陷识别已成为提升产品质量与生产效率的关键。传统电学、图像监测技术在高温、高湿且高速生产环境中,稳定性欠佳、识别精度较低。基于此,设计并实现了基于光纤传感技术的纸张质量监测与缺陷识别系统。该系统融合光纤光栅(FBG)传感阵列、信号采集模块以及智能识别算法,通过多点分布式感知达成对纸张厚度、密度、张力及表面缺陷的在线识别。经实验得知,该系统在检测精度、响应速度、环境适应性上都优于传统方法,能够为造纸产业升级提供重要支撑。
Against the backdrop of the continuous advancement of intelligence in the papermaking industry,online monitoring of paper quality and defect identification have become the key to improving product quality and production efficiency.Traditional electrical and image monitoring technologies have poor stability and low recognition accuracy in high-temperature,high-humidity and highspeed production environments.Therefore,this paper designs and implements a paper quality monitoring and defect identification system based on optical fiber sensing technology.This system integrates fiber Bragg grating(FBG)sensing arrays,signal acquisition modules,and intelligent recognition algorithms,achieving online recognition of paper thickness,density,tension,and surface defects through multi-point distributed perception.It has been found through experiments that this system outperforms traditional methods in terms of detection accuracy,response speed and environmental adaptability,and can provide important support for the upgrading of the papermaking industry.
