Abstract
To solve the problem of long-distance pipeline safety monitoring, a 3-D long-distance early warning system combined with geographic information system based on Sagnac optical fiber interference was proposed. By using digital filtering and wavelet analysis, the system positioning accuracy reached to ± 25m in a laboratory environment of 60km long and one meter underground. The system was also tested in a real pipeline of 211km, and alarm report was gotted successfully with positioning accuracy under ± 150m when excavating about 1m around optics fiber cable. Both false positive rate and negative rate of alarm system were less than 5%. The test proves that the system is applicable in terms of long-distance oil and gas pipeline safety warning.关键词
