【摘要】：石油和天然气是十分重要的能源,这些能源能够极大的推动社会的发展。石油和天然气通常需要远距离运输,使用管道运输解决了这个问题。随着科技的不断发展,世界各国都建立了大量的油气管道,管道的安全问题变得十分重要,但管道长度十分长,排列错综复杂,这为管道的检测带来了困难。本文设计了油气管道综合数据压缩系统对管道数据进行压缩,同时设计了三维油气管道形变可视化描述系统模拟出了油气管道的三维模型,能够直观的检测到管道形变的位置。首先,需要对探测器采集到的管道数据进行处理。由于管道的数据量很大,需要将管道数据进行压缩,由此设计了油气管道综合数据压缩系统,这个系统分为硬件平台和软件平台两个部分。硬件平台通过串口从软件平台接收油气管道的形变数据,使用游程长度编码对油气管道的形变数据进行压缩,再将压缩后的数据通过串口发送到软件平台,软件平台对压缩后的油气管道形变数据进行解压缩。其次,设计了三维油气管道形变可视化描述系统,使用Open GL技术模拟出油气管道的三维可视化模型,通过颜色变化显示出油气管道形变的位置,并且从各个角度对油气管道进行观察。最后,将油气管道综合数据压缩系统和三维油气管道形变可视化描述系统进行整合,并验证整合后的系统能够正常运行。
[Abstract]:Oil and gas are very important sources of energy, which can greatly promote the development of society. Oil and gas usually need to be transported over long distances. Pipeline transportation has solved this problem. With the development of science and technology, a large number of oil and gas pipelines have been established all over the world. The safety of pipelines becomes very important, but the length of pipelines is very long and the arrangement is complicated. This brings difficulties for pipeline detection. In this paper, a comprehensive data compression system for oil and gas pipeline is designed to compress the pipeline data. At the same time, the three-dimensional oil and gas pipeline deformation visualization system is designed to simulate the three-dimensional model of oil and gas pipeline, which can directly detect the location of pipeline deformation. The pipeline data collected by the detector need to be processed. Because of the large amount of pipeline data, the pipeline data need to be compressed, so a comprehensive data compression system for oil and gas pipeline is designed. The system is divided into two parts: hardware platform and software platform. The hardware platform receives the deformation data of oil and gas pipeline through serial port, and compresses the deformation data of oil and gas pipeline using run length coding. Then the compressed data is sent to the software platform through the serial port. The software platform decompresses the compressed oil and gas pipeline deformation data. Secondly, a 3D visualization description system of oil and gas pipeline deformation is designed. The 3D visualization model of oil and gas pipeline is simulated by Open GL technology. The position of oil and gas pipeline deformation is shown by color change, and the oil and gas pipeline is observed from various angles. Finally. The integrated data compression system of oil and gas pipeline and the visualization description system of 3D oil and gas pipeline deformation are integrated and verified that the integrated system can operate normally.
