Abstract

The invention discloses an array-type pickup pipe positioning device and method. The method includes: obtaining a region to be tested, wherein both ends of the pipe are respectively exposed on the edge of the region to be tested or outside the region to be tested; Acquiring the position points of each of the pickups in the pickup array arranged in the area to be tested, wherein the pickup array is distributed along the line direction of the two ends of the pipeline; acquiring the sound signal detected by each of the pickups Intensity, wherein, the sound signal is generated by the vibration of the pipeline; according to the intensity of the sound signal detected by each of the pickups and the position of each of the pickups to determine the direction of the pipeline; the method proposed by the present invention, by Multiple pickups are arranged in an array in the area to be tested. Multiple pickups simultaneously detect the sound signals from the pipeline to be tested underground in the area to be tested, and can quickly obtain the direction information of the pipeline to be tested. The operation is simple and the result is accurate.

Description

technical field [0001] The invention relates to the field of underground pipeline detection, in particular to an array type pickup pipeline positioning device and method. Background technique [0002] With the development of science and technology, the material of urban underground pipes is also constantly changing. In the past, a large number of metal pipes were used, but now in various pipe networks such as water supply, drainage, heat, industry, etc., non-metallic pipes such as plastics and ceramics are used. It is also becoming more and more popular; because these non-metals have the advantages of strong pollution resistance, light weight, low cost, not easy to corrode, easy to bury and maintain, etc., they have been used more and more to replace metal pipes; non-metal pipelines mainly include similar FRP , engineering plastics or composite plastics (PVC, PE, PPR, etc.) It is very inconvenient. With the extensive application of non-metallic pipelines, there are some met...
