【摘要】：ILI(in-line inspection)管道在线检测对油气输送管道安全可靠运行至关重要。设计开发了一种全新的基于螺旋测量原理的主动螺旋管道测量装置,该装置能够自主生成管道测量螺旋线,整合了位移传感器和角度传感器,进行了管道测量对比实验以及管道缺陷检测实验;实验数据采用MATLAB处理,反演出管道内壁模型,通过对管道内壁模型的分析来判断管道内部的情况。实验证明了分度式主动螺旋测量方法的可行性,通过对比实验分析了分度式螺旋测量与普通螺旋测量的区别,实验结果表明:该方法描述管道内壁的三维模型更精确,能被管道机器人或管道猪牵引进行测量作业。特别对于微小管径管道、非管道猪管道有一定的应用前景。
[Abstract]:ILI (in-line inspection) pipeline on-line detection is very important to the safe and reliable operation of oil and gas pipeline. A new active helical pipe measuring device based on helical measurement principle is designed and developed. The device can generate the spiral line of pipeline measurement independently and integrate displacement sensor and angle sensor. The experimental data are processed by MATLAB, and the inner wall model of the pipeline is inversely presented. The analysis of the model of the inner wall of the pipeline is used to judge the situation of the pipeline. The experiment proves the feasibility of the indexing active spiral measurement method. The difference between the indexing spiral measurement and the ordinary spiral measurement is analyzed by contrast experiments. The experimental results show that the method is more accurate in describing the three-dimensional model of the inner wall of the pipe. Can be towed by plumbing robot or pipe-pig for measuring operation. Especially for micro-diameter pipe, non-pipeline pig pipeline has a certain application prospects.
