Temperature measurement cable network that leaks hunting based on heating power pipeline

Temperature measurement cable network that leaks hunting based on heating power pipeline, through based on the heating power pipeline pipe network, the optical cable is laid to whole journey on heating power pipeline, utilize monitoring mode switch device, the range of can be enough interfering phase signal through rayleigh scattering light changes and reveals that the temperature that leads to becomes and/or the corresponding relation of noise disturbing signal, obtain this range change and positional information in order to confirm the pipeline leakage point, can concern with the corresponding relation of temperature and the location that combines to utilize fei nieer light reflex information through brillouin's light scattered signal's frequency displacement again, obtain along the temperature information of each point correspondence of optic fibre, thereby be favorable to realizing whole non -blind area leak detection and temperature anomaly monitoring to each heating power pipeline of heating power pipe
