Description

Technical Field

[0001] The present invention relates to the field of gas pipelines, and in particular to an abnormal alarm system for gas pipeline laying scenarios. Background Art

[0002] During the construction of gas pipelines, in order to avoid the pipe body weld facing the wall, the pipes with unclear welds should be marked in advance. The installation of copper pipes or stainless steel corrugated pipes laid in the pipeline shaft has been carried out after the drawings and other pipeline construction are completed. When the pipeline passes through the partition board in the shaft, a casing should be added, and there should be a spacing of not less than 5mm between the casing and the pipeline. Concealed gas copper pipes or stainless steel corrugated pipes should not come into contact with various metals and wires; when it is unavoidable, they should be separated by insulating materials. The holes for gas pipelines to pass through the floor slabs should be drilled from the highest floor downwards, and the position of the holes in the lower floor should be determined vertically with a heavy hammer layer by layer; when the upper and lower walls are different in thickness and cannot be vertically aligned, it is advisable to make an "U" bend to make it close to the wall to avoid turning with pipe fittings.

[0003] However, at the gas pipeline laying site, in order to supplement the gas supply when the gas pipeline is blocked or provide more stoves for cooking food, one or more bottled liquefied gas tanks are usually introduced to supply gas to the stoves on site. However, this gas usage scenario of adding bottled liquefied gas tanks at the gas pipeline laying site adds the risk of gas failure.

[0004] CN113772575A discloses a pressure pipeline laying device for urban gas engineering in the technical field of gas pipeline laying equipment, comprising a mounting frame and a hydraulic lifting mechanism, a movable groove is opened on the outer wall at the bottom of the connecting plate, two groups of movable blocks are slidably installed in the inner cavity of the movable groove, and the outer walls on one side of the two groups of movable plates close to each other are both installed with a fixing component, the fixing component comprises a movable plate movably connected to the outer wall of the movable plate, and the outer walls on one side of the two groups of movable plates close to each other are both installed with a clamping plate, and the rotating rod of the fixing component rotates in the inner cavity of the mounting hole, the guide block slides in the inner cavity of the guide groove, and the rotating block rotates in the inner cavity of the opening, so as to compensate for the fixed pipeline, so that the laying equipment will not cause squeezing to the pipeline when moving in an uneven area, thereby protecting the pipeline and protecting the service life of the pipeline.

[0005] CN112576813A discloses a natural gas pipeline laying system, comprising a mobile frame, mobile wheels, a transport mechanism and a material discharge mechanism. The present invention can solve the problem that in the process of natural gas pipeline laying construction, the natural gas pipeline to be laid is often placed manually in the groove to be laid, and the spacing between each section of the natural gas pipeline is manually adjusted. During this period, since the number of natural gas pipelines to be laid is large and they are located below the groove, manual labor is required to go down into the groove to accurately position the natural gas pipeline, and relatively large size errors may be caused between the natural gas pipelines laid by different workers, which affects the subsequent welding operation, the labor intensity of manual operation is high, and the work efficiency of the laying operation is reduced.

[0006] CN115750914A discloses a gas pressure pipeline laying device, including a frame and a connecting plate, wherein a rectangular card frame is fixedly connected to one side of the outer surface of the frame, a rectangular card block is fixedly connected to one side of the outer surface of the connecting plate, the inner wall size and shape of the rectangular card frame are adapted to the size and shape of the outer surface of the rectangular card block, and a reserved installation plate is fixedly connected to one side of the outer surface of the connecting plate away from the rectangular card block. The gas pressure pipeline laying device, driven by the first threaded rod and the first screw hole block, can drive the dovetail slide rod and the cylinder to move, and then drive the second rectangular plate and the rolling wheel to move, and then adjust the horizontal position distance of the rolling wheel, so that the distance interval between the two rolling wheels becomes larger, and then can adapt to pipeline placement grooves of different widths, and when the frame moves forward, the first push plate can push large blocking materials. Summary of the invention

Otherwise, the wireless transmission of dangerous scene alarm information to the remote gas pipeline management server through the wireless communication link is temporarily suspended, thereby realizing real-time network alarm for dangerous scenes where bottled liquefied tanks exist in the gas pipeline laying environment.

[0013] A data analysis device is connected to the customized enhancement device and includes a micro-control unit, a pattern storage unit, a block detection unit and an instruction trigger unit. The micro-control unit is connected to the pattern storage unit, the block detection unit and the instruction trigger unit respectively. The data analysis device is used to detect image blocks with the same shape as the set standard bottled liquefied tank pattern from the directional enhancement image according to the set standard bottled liquefied tank pattern, perform a process of normalizing the image blocks with the size of the set standard bottled liquefied tank pattern to obtain corresponding typical image blocks, and the typical image blocks are consistent with the size of the set standard bottled liquefied tank pattern. , obtaining pixel values ​​corresponding to pixel points of the typical image blocks as first-category pixel values, obtaining pixel values ​​corresponding to pixel points of a set standard bottled liquefied tank body pattern as first-category pixel values, performing pixel-by-pixel difference processing on the typical image blocks and the set standard bottled liquefied tank body pattern to obtain a difference processing picture, counting the total number of pixel points with a pixel value of 0 in the interpolation processing picture as a reference statistical number, issuing a bottled liquefied tank body detection instruction when the reference statistical number exceeds a limit, and issuing a bottled liquefied tank body non-detection instruction when the reference statistical value does not exceed a limit;

[0014] The wireless alarm device is connected to the data analysis device and is used to wirelessly transmit dangerous scene alarm information to a remote gas pipeline management server through a wireless communication link when receiving a bottled liquefied tank detection instruction.

[0017] Second: the wireless alarm device is used to wirelessly transmit the dangerous scene alarm information to the remote gas pipeline management server through the wireless communication link when receiving the bottled liquefied tank detection instruction; otherwise, the wireless transmission of the dangerous scene alarm information to the remote gas pipeline management server through the wireless communication link is temporarily suspended, thereby realizing the real-time network alarm of the dangerous scene of the bottled liquefied tank in the gas pipeline laying environment;
