管道位置检测技术方案研究

STUDY ON THE SCHEME OF PIPELINE ORIENTATION MEASUREMENT

油气管道铺设以后,需要定期或不定期的进行位置检测,特别是水下管道。传统的检测方法是采用GPS与管道探测仪配合,不仅工作量大、成本高,精度也不高。介绍一种以惯性器件为基础的定位方案,与管道位置有关的检测信息存储在采集系统中,避免了外界环境的干扰,可以提高系统的可靠性、大大的减少了检测工作量与检测成本。

The underground oil and gas pipelines, especially the pipelines under the water, need steady or periodic-unsteady position inspection. The traditional method is carried out with GPS and detected apparatus, which results in huge workload and high costs, what is more, it could not reach an expected precision. An orientation project based on inertial device was introduced in the paper. The information of position was stored in the collection system to avoid disturbing by the outside environment; therefore, it increases the system's reliability and definitely decreases the workload and costs.
