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.
