Smart Oil Pipeline Network Timing Standardization Fragment Inspection Technology Based on Buffer Zone Analysis and Spatial Overlay Analysis

传统的智慧石油管网时序标准化片段巡检技术仅对采集的数据进行降噪处理,巡检效果不佳。设计了缓冲区分析和空间叠加分析下的智慧石油管网时序标准化片段巡检技术。利用红外图像采集设备,对石油管网运行过程中的数据进行采集,并对采集的数据进行灰度化、对比度增强和降噪处理。利用空间叠加分析的特性,将预处理的图像数据进行叠加,通过计算提取叠加后的图像数据特征,在缓冲区分析的作用下设定巡检路径规划三维空间,通过计算巡检点到虚拟直线之间的距离构建相应的巡检路径规划模型,通过对规划的巡检路径进行评价,判断当前路径是否符合要求,从而完成对石油管网时序标准化片段的巡检。仿真实验表明,缓冲区分析和空间叠加分析下的智慧石油管网时序标准化片段巡检技术的巡检安全性指标为0.954,与传统的智慧石油管网时序标准化片段巡检技术相比巡检效果更好,可靠性更强。

The previous smart oil pipeline network timing standardization fragment inspection technology only performed noise reduction on the collected data,resulting in poor inspection results.Therefore,a smart oil pipeline network timing standardization fragment inspection technology was developed based on buffer zone analysis and spatial overlay analysis.Infrared image-capturing equipment was used to capture the operation process of oil pipeline networks,and the collected data was greyed out,contrast-enhanced and denoised.Using the characteristics of spatial overlay analysis,the pre-processed image data was overlaid,and the features of the overlaid image data were extracted by calculation.Under the action of buffer zone analysis,the inspection path was set to plan a three-dimensional space,and the distance between the inspection point and the virtual line was calculated.A corresponding inspection path planning model was built,and the planned inspection path was evaluated to determine whether the current path met the requirements,thus completing the inspection of standardized fragment of the oil pipeline network timing.Through the above design,the design of a standardized fragment inspection technology for smart oil pipeline network timing was completed.The simulation experiment results show that,compared with the previous smart oil pipeline network timing standardization fragment inspection technology,the designed buffer zone analysis and spatial overlay analysis of the smart oil pipeline network timing standardization fragment inspection technology has a safety index of 0.954,which has a better inspection effect and stronger reliability.
