Pipeline traceability method based on acoustic imaging technology

Abstract

The invention discloses a pipeline traceability method based on an acoustic imaging technology. The method comprises the steps of giving a noise source to a pipeline source or a middle section; shooting at the tail end of a pipeline by using an acoustic imager, and displaying the distribution condition of the noise source at the tail end of the pipeline; and tracing a pipeline tail end matched with the pipeline source according to the distribution condition of the noise source. The pipeline traceability method based on the acoustic imaging technology can be used for traceability of old pipelines of existing buildings, and implementation is more convenient, faster and more accurate. According to the method, tracing of an air inlet pipe and an air outlet pipe in the high and large space can be rapidly achieved, and operation on the ground is facilitated. The method is also beneficial to an updating and reconstruction project of an air-conditioning system of an existing building, the pipeline trend is analyzed, and repeated disassembly and reconstruction are avoided. The requirements on operation site conditions are not high, and the traceability precision is high.

Description

technical field [0001] The invention relates to the technical field of pipeline detection, in particular to a pipeline traceability method based on acoustic imaging technology. Background technique [0002] After the air ducts and water pipes of existing buildings have been used for many years, there is often a phenomenon of mixed connection of air inlet pipes and exhaust pipes, rainwater and sewage, and some add branch pipes in the middle of the air pipes. After a certain period of use, it is impossible to find the source of the pipes, increasing Reduced the difficulty of pipeline maintenance and rectification. Conventional pipeline traceability methods include visual detection, robot detection, sonar, surveying and mapping, etc., which require relatively large workload and long inspection time. Contents of the invention [0003] Aiming at the deficiencies in the above-mentioned prior art, the present invention proposes a pipeline traceability method based on acoustic im...
