In the operation process of the pipeline, frequent interference of urban infrastructure activities exists, and the gas pipeline has more or less defects, so that each large gas company carries out internal detection operation on the gas pipeline, and then discovers and repairs the defects of the major pipeline body.

Therefore, when the pipeline is changed, the existing data alignment method is difficult to meet the detection requirement.
Thus, there is a need for improvements and enhancements in the art.

Exemplary method
The method for aligning the pipeline data after the gas pipeline is relocated in the embodiment can be applied to terminal equipment, and the terminal equipment comprises: mobile phones, computers and other intelligent terminal products. Specifically, as shown in fig. 1, the method for aligning pipeline data after the gas pipeline is relocated in this embodiment includes the following steps:
s100, determining a relocation section in a gas pipeline, and acquiring the number of welding lines between the valve which is positioned at two sides of the relocation section and is closest to the relocation section and the relocation section.
Since in the prior art, the gas pipeline cannot be detected in the moved pipeline after being changed, the changed section may be a newly added section or a reduced section for the pipeline laying requirement, as shown in fig. 2. Therefore, in the embodiment, after the gas pipeline is changed, the changed section of the gas pipeline is determined, the position of the changed section is located, and then the area of the changed section in the whole gas pipeline is obtained, so that the number of welding seams between the two sides of the changed section and the nearest valve on the gas pipeline is determined.
In an implementation manner, the step S100 specifically includes the following steps:
s101, determining the relocation section in the gas pipeline, and acquiring coordinate position information of the relocation section;
and S102, acquiring the number of welding lines between the valve which is positioned at two sides of the transition section and is closest to the transition section and the transition section according to the coordinate position information.
Specifically, in this embodiment, the relocation section in the gas pipeline is determined first, and coordinate position information of the relocation section is obtained; and determining a relocation start point coordinate (such as an X coordinate, a Y coordinate and a Z coordinate) and a relocation end point coordinate (such as an X coordinate, a Y coordinate and a Z coordinate) of the relocation section according to the coordinate position information. And determining a first valve closest to the relocation start point and a second valve closest to the relocation end point according to the relocation start point coordinate and the relocation end point coordinate, and then calculating the number of first welding seams between the relocation start point and the first valve and the number of second welding seams between the relocation end point and the second valve. The length of one steel pipe is about 12 meters, and the number of first welding seams from the starting point of the transition section to the nearest first valve can be obtained through division operation.
And S200, performing data alignment on a pipeline positioned in front of the relocation section and a pipeline positioned behind the relocation section in the gas pipeline based on the number of the welding seams.
Since the number of the welding seams in this embodiment is calculated based on the relocation section, after the number of the welding seams is obtained, the present embodiment aligns data of a pipeline located before the relocation section and a pipeline located after the relocation section in the gas pipeline based on the number of the welding seams. In the process of internal detection operation, pipeline basic data and pipeline defect data can be detected, wherein the pipeline basic data comprise welding seams, valves, tee joints and the like, the pipeline defect data comprise deformation, welding seam abnormity, metal loss and the like, and the position of each type of data on the pipeline is identified through an absolute mileage value. The premise of the internal detection data alignment is that key points are aligned, the key points comprise welding seams, valves, tee joints and other remarkable characteristic points, and the data alignment method mentioned in the embodiment is to perform alignment operation by taking the welding seams and the valves as the key points.
In one implementation manner, the embodiment includes the following steps when performing data alignment:
step S201, acquiring detection data in two batches before and after relocation, and aligning the detection data in the two batches before and after relocation from a first welding line;
step S202, when the first valve is reached, the number of the first welding lines is continued, and then data alignment is carried out;
and S203, when the relocation terminal point is reached, carrying out data alignment along the number of the second welding lines.
In specific implementation, as shown in fig. 3, the detection data in the two batches before and after relocation are aligned from the first weld, and when the distance between the two welds is smaller than a set threshold, the two welds can be automatically aligned together. The long vertical lines in fig. 3 are the valves on the pipeline and the short vertical lines are the welds on the pipeline. During alignment, the embodiment starts alignment from the first leftmost weld joint in fig. 3, and obtains the weld joint position with the same mileage value in the detection data before and after relocation; and if the distance between the two welding seams is smaller than a set threshold value, automatically aligning. When the pipeline arrives at the first valve, because the pipeline is changed, if the number of the first welding seams between the change starting point and the first valve is N, the embodiment carries out alignment operation after the first welding seams arrive at the first valve. And if the number of the second welding seams between the relocation terminal point and the second valve is M, the alignment operation is performed after the relocation terminal point is reached and the M welding seams are extended. That is to say, in this embodiment, after the pipeline is relocated, when data alignment is performed, the number of welds between two sides of the relocated segment and the valve closest to the relocated segment is used for carrying out the alignment, so that all welds except for the relocated segment can be aligned, the defect data can be determined, and the detection accuracy is improved. And the internal detection data of the transition section can be used as the data alignment when the next internal detection is carried out.
Step S300, in the process of data alignment, determining pipeline defect data.
In the embodiment, in the data alignment process of two batches of welding seams, the defect position is increased or decreased equidistantly according to the modification of the mileage value of the previous welding seam, so that the defect position is generated, as shown in fig. 4, the point in fig. 4 is the defect on the pipeline, and the two batches of defect data are regarded as the same defect according to the same type, the same pipeline circumferential direction and the same mileage value. Therefore, in the data alignment process, the defect data which belong to the same type and are in the same pipeline circumferential direction and have the same mileage value can be obtained from the detection data in the two batches before and after the relocation, so that the development trend of the defect and the residual service life of the pipeline can be estimated according to the determined defect data.
In summary, in this embodiment, a transition section in a gas pipeline is first determined, and the number of welds between a valve located on both sides of the transition section and closest to the transition section and the transition section is obtained; based on the number of the welding lines, performing data alignment on a pipeline positioned in front of the relocation section and a pipeline positioned behind the relocation section in the gas pipeline; and determining the pipeline defect data in the process of data alignment. The invention can align data after the gas pipeline is changed and detect the defects of the pipeline in time, thereby being convenient for repairing the defects in time.
