Application of Distributed Temperature Monitoring System of Optical Fiber in Coal Preparation Plant

In view of main factors and characteristics of cable fire disaster of coal preparation plant, the paper proposed a design scheme of distributed temperature monitoring system of optical fiber. It introduced working principle, composition, man-machine interface and functions of the system. The actual application showed that the system can monitor and control temperature of cable interlayer, cable bridge and critical areas of electrical system realtimely, so as to ensure safety production of coal preparation plant.
