Problems solved by technology

[0002] The traditional way to find the location of geographic pipelines is to confirm the location of the underground pipeline network by construction drawings, metal detectors, and ultrasonic echo detection. Due to irregular drawings, damage caused by rodents and insects, and poor management and relocation, many old pipelines are lost. Network maintenance has caused great difficulties, especially for the detection of gas pipeline leakage, which has caused huge safety hazards to the safety of people's lives and property. Moreover, traditional metal detection methods cannot detect and trace non-metallic materials, nor can they Like the power pipe network, it uses its own magnetic field as a detection method
Ultrasonic echo is greatly affected by geology and the equipment is bulky, and the operator has high technical requirements and cannot be popularized

Embodiment 2

[0033] Embodiment 2, specifically, sensor assemblies 5 are installed in any four adjustment frames 41 on the vibration receiver 4, which can correct pseudoranges to obtain correct position coordinates. When the number of sensor components 5 on the vibration receiver 4 is four, through the attenuation rate, four uncertain distances ν are obtained, four uncertain distances and four accurate distances are used to construct four equations, and the obtained results can be corrected Pseudo-range to get the exact location of the vibration source.

Embodiment 3

[0034] Embodiment 3, specifically, sensor assemblies 5 are installed in any five adjustment frames 41 on the vibration receiver 4, and an accurate position coordinate can be obtained for any four. When the number of sensor components 5 on the vibration receiver 4 is five or more, any four sensor components 5 can obtain an accurate vibration point position, so that the position and direction of the pipeline can be virtually synthesized by software without artificial Mobile for multiple measurements and resynthesis, improve work efficiency and accuracy, and facilitate data transmission, storage and grid connection.

[0035] It should be noted that when the number of vibration receivers 4 is one, according to the geological attenuation coefficient , to obtain the distance I between the vibration source and the vibration receiver 4 1 =I 0 , which is an ideal hemisphere, can measure any direction of the spherical surface of the vibration source, and obtain the distance between...
