基于RFID电子标签的螺栓松动检测技术
A Bolt Loosening Detection Technology Based on RFID Tags
摘要
Abstract
In the field of bolt loosening detection,manual inspection has problems such as low efficiency and insufficient accuracy.Detection relying on conventional sensors uses cables for power supply and data collection,re-sulting in high installation and maintenance costs.To address the above issues,this study designs an ultra-high fre-quency radio frequency identification devices tag for bolt loosening detection based on radio frequency identification technology.When the bolt loosens,the tag antenna installed on the nut and the connected component deforms,which causes a change in the resonant frequency of the antenna.This further leads to a variation in the backscattered signal strength of the tag.The wireless monitoring of the bolt loosening state is realized by remotely reading the change in the backscattered signal strength.Experimental results show that as the bolt loosening angle increases,the backscat-tered signal strength of the tag shows a linear downward trend,with a correlation coefficient as high as 0.978 74,which confirms that the proposed detection scheme can achieve accurate identification of the bolt loosening state with-in the loosening angle range of 0° to 8°.关键词
