A Low-Cost Intelligent Foam Gauge for Pipeline Detection
-
摘要: 提出了一种新型低成本、低风险、有检测功能的泡沫测径器。该泡沫测径器通过安装在泡沫载体上的传感器采集管道内径变化，通过集成在电路板上的陀螺仪对管道走向进行定位，其检测能力与传统价格昂贵的多功能管道内检测器相近。介绍了该新型泡沫测径器的工作原理及其结构设计，在实验室环境对关键部件的可靠性进行了验证试验。使用专门软件对获得的原始数据进行处理并可视化。最后，在现场测试中，对一条8 km管道的两次测试数据进行综合分析，并与传统意义上的“智能清管器”的采集数据做出比较。结果表明，该检测器能够提供更多相关管道结构的信息，具有更好的灵敏度和附加功能。Abstract: In this paper, a new type of low cost, low risking, and detectable foam pig is proposed. The sensor mounted on the foam carrier captures the variation of the pipe diameter and positions the pipe by the gyro integrated in the circuit board. Its detection capability is similar with that of the traditional multi-functional detector of high cost. This article aims to describe how the new foam caliper works and how to design its structure to verify the reliability of key components in a lab environment. Special software was used to deal with the obtained raw data and with the visualization. Finally, in the field test, a comprehensive analysis of the data obtained from two tests on an 8 km pipeline was made and compared with the collected data of the "intelligent pig" in the traditional sense. The results showed that the gauge could provide more information about the pipeline structure, and had better sensitivity and additional functions.
