The aim of this paper is to present a distributed optical fiber temperature measurement system and method based on Raman scattering and optical time domain reflection for dry reactors

aiming at solving the monitoring defects of traditional test methods. A temperature sensing cable and its component system are applied to the temperature monitoring of the dry reactor. When the temperature data of the device is monitored abnormally

the system issues an early warning report signal to prevent the problem from continuing to develop under the uncontrolled situation. And minimize the damage caused by the failure. It is a temperature measurement system with simple overall structure

convenient monitoring and high security. This paper will focus on the implementation technology.
