Yan Chang, Yonghua Wang, Wenyou Fan · 2009
The positioning of damaged points in outer anticorrosion coating of underground pipelines and informational management of these damaged points is significant for pipelines risk management. It plays an important role in security management of pipelines. The functions, such as positioning as well as informational management ensure the safe operation of pipeline. This paper firstly introduced the basic principles of the CORS and function module of embedded GIS, and then given the example of how to use methods such as embedded GIS, CORS, as well as geophysical to integrate coordinates collected into attribute edited. According to inquire the figure of insulation resistance of coating and the number of damaged points in a given distance, it evaluated condition of Anti-corrosion layer. With the help of embedded GIS visiting database, which 3G network keep the database update, it can evaluate present condition of Anti-corrosion layer. It will become more efficient and effective to use embedded GIS management as well as CORS positioning technology in the inspection of outer anticorrosion coating of underground pipelines. It also can provide basis for anticorrosion maintenance.
