Pipeline transportation, one of the five transportation modes, is becoming the life line of national economic development. Pipeline transportation is a main way of oil and gas transportation, has the advantages of economy, safety, high efficiency, stability and the like, and plays an important role in national economy. The leakage of pipelines for oil, gas and water transportation brings about casualties and great economic loss, and seriously pollutes the environment.

In recent years, accidents of urban water supply networks in China frequently occur, the leakage of the water supply networks is serious, the scale of the accidents is continuously upgraded, the average leakage rate of urban water supply is 17.7 percent and is far higher than 12 percent required by the leakage control and evaluation standard of the urban water supply networks, billions of elements are lost due to leakage of water pipes in China every year, and a large amount of water resources are wasted.

Therefore, the timely discovery and positioning of the pipeline leakage have important practical significance and social significance in the aspects of ensuring public safety, protecting the environment, reducing transportation loss, saving energy and improving economic benefits.

There are various methods for detecting pipeline leakage, and the methods are classified into direct detection methods and indirect detection methods according to detection modes. The direct detection method mainly comprises a ground manual online observation or patrol method, an acoustic method, a physical and chemical method, an optical fiber leak detection method and the like. The indirect detection method is to collect the pressure, flow and leakage point sound wave data in the pipeline by high-precision sensors and other equipment, and locate the leakage point by algorithms such as data processing, computer simulation and the like.

According to the working mode, the method can be divided into an external detection method and an internal detection method. The detection technology in the pipeline is that an intelligent pipe cleaner (a detector in the pipeline) loaded with nondestructive detection equipment and a data acquisition, synchronization and storage system runs in the pipeline to acquire the corrosion condition, the defect, the welding seam condition and the like of the inner wall of the pipeline, so that the scanning of the pipe body is completed, and the detection purpose of accurately knowing the size and the position of the defect is achieved. The detection in the pipeline is not influenced by geographical environment, climate and the like, and the detection is more random and reliable.

The invention patent with the publication number of CN103423600A discloses a small leakage detection system for a liquid pipeline, wherein a leakage detection ball flows with a medium in the pipeline, and meanwhile, an in-pipe sound signal, leakage detection ball state information are collected and stored, and a time label is marked, so that the leakage position of the pipeline can be determined. However, the system cannot adjust the advancing direction of the detection ball, and when the detection ball is stuck by an obstacle, the detection ball cannot break through the obstacle by itself, and the detection ball cannot reach the end point.

It should be noted that the above background description is provided for clarity and completeness of description of the present invention and for understanding by those skilled in the art. These solutions are not considered to be known to the person skilled in the art merely because they have been set forth in the background section of the present invention.
