2 System for detecting water leakage using 2 channel fiber-optic temperature sensor

摘要

Provides a technology that can detect leaks at low and precise locations where water, including rivers, is stored, and provides technology that can detect leak points with a very accurate probability based on surrounding environmental information. A water leakage detection system using a two-channel optical fiber temperature sensor according to an embodiment of the present invention includes a water leakage detection system embedded in a bottom surface in contact with water in a place where water is present and is provided with light from a light source, At least one sensor for reflecting light of different wavelengths according to temperature is provided for each of at least one temperature measurement point; A second optical fiber line installed at a predetermined height from the water surface, wherein at least one sensor is installed for each of at least one temperature measurement point; And the wavelengths of the light reflected from the sensors included in the first optical fiber line and the second optical fiber line are measured to measure temperature information for each temperature measurement point, and the leakage information for at least one temperature measurement point And a leak detection unit for detecting the leaked water.
