基于GPS-RTK的管道外检测数字化应用

Digital Application of External Detection Based on GPS-RTK

为实现管道外检测信息数字化,结合GPS-RTK测量技术,将外检测数据与地理位置信息高度关联。利用该技术可实现外检测数据(如漏损点位置等)在空间上cm级精确定位,通过地图系统可直观查看检测数据在管道上的位置分布,为管道漏损点维修计划制订、现场开挖维修、内外检测数据对齐分析、管道中线测量等提供了精确的数据。

In order to realize the digitization of the external detection information,combined with the GPS-RTK measurement technology,the external detection data was highly correlated with the geographical location information.The technology can realize the accurate positioning of the external detection data such as the position of the leakage point in the space centimeter level.The map system can intuitively view the position distribution of the detection data on the pipeline,and provide accurate data for formulating the maintenance plan for the pipeline leakage point,on-site excavation and maintenance,alignment analysis of internal and external inspection data,and mid-line measurement of pipelines.
