土方施工单位使用重型挖掘机械作业时有可能损伤或破坏管道。美国天然气研究所及其合作伙伴开发一种商用管道实时监测系统,该系统可探测在管道附近施工的挖掘机械产生的声信号,传感器间隔在16km以上。 研究发现,该系统在管道输送流体的噪音背景条件下,仍能在一定距离测出机械接触管道的声音。滤波器提高了信 When using heavy excavation machinery, earthwork construction units may damage or destroy the pipeline. The Natural Gas Research Institute and its partners have developed a real-time monitoring system for commercial pipelines that detects acoustic signals from excavating machinery constructed near pipelines with sensors spaced over 16km. The study found that the system can detect the sound of mechanical contact pipes at a distance under the background noise of the fluid in the pipeline. Filter improves the letter
