In this embodiment, the pipeline is traversed by the traveling system 1 capable of automatically traveling in the pipeline, and the traveling system 1 is provided with the deformation detection system 2, the positioning system 3, and the control system 4. Wherein, deformation detecting system 2 is used for running system 1 in the in-process of walking, detects the deformation of pipeline, and when detecting the pipeline deformation, control system 4 acquires positioning system 3's locating information to send locating information to the host computer, the host computer is after acquiring locating information, maintains or changes the pipeline according to locating information convenience.

The first crawler 12, the second crawler 13 and the third crawler 14 are 120 degrees, which is beneficial to improving the stability of the walking system 1 walking in the pipeline.
In this embodiment, the front end of the vehicle body 11 is provided with a first sliding column 15, a second sliding column, and a third sliding column along the traveling direction of the traveling system 1.

Due to the fact that the pipe diameters of different pipes are different, the first crawler 12, the second crawler 13 and the third crawler 14 need to be adjusted to achieve adjustment of the heights of the pipes, and therefore the pipes are suitable for the pipes with different pipe diameters. When the pipe diameter of the pipeline is smaller than the original height of the first crawler 12, the second crawler 13 and the third crawler 14, the sliding block 16 is pushed forwards under the compression action of the elastic part 18, so that the height of the first crawler 12, the height of the second crawler 13 and the height of the third crawler 14 are reduced to adapt to the pipe diameter, and meanwhile, the elastic part 18 enables the first crawler 12, the second crawler 13 and the third crawler 14 to be tightly attached to the pipe wall, so that the walking system 1 is more stable in walking.

The line CCD image sensor 23 is a photoelectric conversion device that can store signal charges generated by light. When a pulse with a specific time sequence is applied to it, the stored signal charges can be directionally transferred in the CCD to realize self-scanning. The linear array CCD image sensor 23 scans image information and performs gray detection to obtain a laser ring track, and whether the pipeline is deformed or not is judged by measuring the distance from a central point to each bright point.

Example two
Embodiment two adds a fall detection system 5 connected to the control system 4 on the basis of embodiment one, as shown in fig. 6.
