Aiming at the coal preparation plant safety issues highlighted in fire detection, we propose a more mature distributed optical fiber temperature measurement system. The system uses optical time domain reflectometry techniques and Raman scattering temperature measurement, temperature measurement by fiber optic cable, fiber optic distributed temperature analyzer and monitor computer, having a high sensitivity and precision. Its application to the achievement of Coal production safety played an important role in the prevention of accidents has important practical value.
