Table 5 Summary of emerging detection and location technologies
From: Current Trends and Perspectives of Detection and Location for Buried Non-Metallic Pipelines
Methods | Detection and Location conditions | Accuracy | Interference | Strengths | Weaknesses |
|---|---|---|---|---|---|
GIS [19] | Streets with GIS | High | Small | Easy operation, high accuracy, 3D display available | Updating topographical data real-time; high expense for maintenance |
In-pipe robot [164] | Open-ended non-metallic pipeline | High | Small | Locate accurately and easily access all conditions inside the pipeline | Limited by the size of the robot and its ability to turn and communicate. |
Various environments and surface | Low | Large | A beneficial supplement to the existing non-metallic pipeline detection methods | The theory of emerging technologies is not perfect, and the equipment is unstable |
