Abstract
Description
Technical Field

[0002] The pressure pipeline axonometric drawing is an important reference material in the pressure pipeline inspection process. It uses wireframe symbols and text to intuitively display the pressure pipeline direction, pipeline components, pipeline properties and other information. In the actual pipeline inspection work, it is often the case that the original pressure pipeline axonometric drawing of the enterprise is lost, or the axonometric drawing exists but does not match the actual pipeline, so the inspectors need to conduct surveying and mapping on the pressure pipeline site.
[0003] When drawing an axonometric diagram of a pressure pipeline, it is necessary to reflect the spatial distance information between the pressure pipeline components. In the case of a long pressure pipeline, or a complex spatial structure of the pipeline, and there is mutual obstruction, it is difficult for one surveying and mapping site to measure the node coordinates of all pipeline components on the pipeline, and multiple surveying and mapping sites need to be set up. Using the existing pressure pipeline axonometric mapping surveying and mapping device or system, the drawn axonometric diagram of the pressure pipeline fails to reflect the spatial distance information of the pipeline, and only indicates the spatial direction of the pressure pipeline and the category of pipeline components. It does not involve the spatial coordinates of the pipeline components, resulting in low integrity and accuracy of the pressure pipeline axonometric diagram. Moreover, this type of surveying and mapping device uses an electronic compass to obtain the horizontal azimuth of the pressure pipeline, but most pressure pipelines are made of steel, which can easily cause magnetic field interference to the electronic compass, resulting in confusion in the acquired pipeline direction data.

[0030] The pressure pipeline axonometric drawing is an important reference material in the pressure pipeline inspection process, and is usually used to assist in identifying the inspection data of various parts of the pipeline. However, many pipelines reported for inspection, especially old pipelines with a long service life, often have lost or incomplete pipeline axonometric drawing files; and some companies provide pipeline axonometric drawings that do not match the actual pipeline direction and cannot be used for on-site inspection. In the case of the above-mentioned axonometric drawing being lost or the axonometric drawing being available but not matching the actual pipeline, the inspector needs to conduct surveying and mapping on the pipeline site.
[0031] The technical solution of the utility model is described in detail below through the accompanying drawings and specific embodiments.
[0032] Please refer to Figure 1 and Figure 2 The present embodiment discloses a pressure pipeline isometric mapping system, including a bracket 100, a two-dimensional pan-tilt platform 200, a measuring module 300 and an angle calibration module 400; the two-dimensional pan-tilt platform 200 is mounted on the bracket 100, and the two-dimensional pan-tilt platform 200 includes a first driving member 210 and a second driving member 220; the measuring module 300 is mounted on the two-dimensional pan-tilt platform 200, and the measuring module 300 is driven by the first driving member 210 to rotate horizontally, and the measuring module 300 is driven by the second driving member 220 to rotate vertically, and the measuring module 300 includes The laser distance measuring component 310, the three-axis gyroscope 320 and the processor 340 are electrically connected to the laser distance measuring component 310 and the three-axis gyroscope 320 respectively. The laser distance measuring component 310 is used to measure the distance between the pipeline node and the measuring module 300, and the three-axis gyroscope 320 is used to measure the horizontal azimuth and pitch angle of the measuring module 300 pointing to the pipeline node; the angle calibration module 400 is installed on the measuring module 300, and the angle calibration module 400 is used to calibrate the horizontal azimuth and pitch angle of the three-axis gyroscope 320. The measurement accuracy of the change in the horizontal azimuth and the change in the pitch angle of the three-axis gyroscope 320 is not affected by the external magnetic field. Compared with the electronic compass, the three-axis gyroscope 320 has a higher angle measurement accuracy. It can accurately measure the node distance, horizontal azimuth and pitch angle of the pipeline node, is not easily affected by the external environment, and the operation process is efficient and simple, which improves the mapping efficiency, adapts to more application scenarios, and improves the integrity and accuracy of the pressure pipeline axonometric drawing.
[0033] It should be noted that the three-axis gyroscope 320 can obtain the horizontal azimuth change and the pitch angle change, but cannot obtain the absolute horizontal azimuth data and the absolute pitch angle data. Before performing the pressure pipeline axonometric mapping, the 0° horizontal azimuth and 0° pitch angle of the three-axis gyroscope 320 in the measurement module 300 need to be calibrated using the angle calibration module 400, so that the azimuth measured by the three-axis gyroscope 320 is the absolute horizontal azimuth, and the measured pitch angle is the pitch angle relative to the horizontal plane. Exemplarily, the first drive member 210 and the second drive member 220 are both servo motors or stepper motors.
