[0058] Please refer to image 3 , image 3 It is a schematic flowchart of a second embodiment of a method for positioning an array-type pickup pipe of the present invention; based on the first embodiment, after acquiring the area to be measured, the method further includes:

[0059] Step S210: Obtain a preset sub-region division rule, and divide the connection direction of the test area at both ends of the pipeline into a plurality of sub-test areas according to the division rule.

[0060] Specifically, please refer to Figure 4 , Figure 4 It is a schematic diagram of the area to be tested and the arrangement of the pickups in the second embodiment of the method for locating the pipes of array-type pickups of the present invention; this embodiment is suitable for relatively large areas to be tested, and the number of pickups 100 is not enough to cover the entire area to be tested. In the case of areas, the area to be tested is divided into multiple sub-area to be tested.

Abstract

The invention discloses an array type sound pick-up pipeline positioning device and method. The method comprises the following steps that: obtaining an area to be detected, wherein two ends of a pipeline are independently exposed on the edge of the area to be detected or out of the area to be detected; obtaining the position point of each sound pick-up in a sound pick-up array of the area to be detected, wherein the sound pick-up arrays are distributed along the connection line direction of two ends of the pipeline; obtaining the intensity of a sound signal detected by each sound pick-up, wherein the sound signal is generated by pipeline vibration; and according to the intensity of the sound signal detected by each sound pick-up and the position point of each sound pick-up, determining a pipeline movement direction. By use of the method which is put forward by the invention, a plurality of sound pick-ups are arranged in the area to be detected in an array way, the plurality of sound pick-ups simultaneously detect the sound signal emitted by the underground pipeline to be detected in the area to be detected, the movement direction information of the pipeline to be detected can be quickly obtained, and the method is simple in operation and has an accurate result.

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 materials of urban underground pipelines are also constantly changing. In the past, metal pipelines were used in large quantities. Nowadays, plastics, ceramics and other non-metallic pipelines are used in various pipe networks such as water supply, drainage, heating, and industry. It is also becoming more and more popular; because these non-metals have the advantages of strong pollution resistance, light weight, low cost, non-corrosion, easy to bury and repair, etc., they have been increasingly used to replace metal pipelines; non-metallic pipelines mainly include similar glass steel , Engineering plastics or composite plastics (PVC, PE, PPR, etc.) pipes are characterized by corrosion resistance, aging resistance, easy construction...
