Abstract

The server in the computer room runs in a closed, narrow, and uninhabited environment. Due to the temperature rise and heat dissipation of the device, faults, burns out, or even fires may occur due to high temperature. At present, the traditional temperature monitoring methods in computer room are limited to electrical method, infrared thermal imaging detection method, fiber Bragg grating measurement method, rarely involving high-precision and continuous measurement methods. By introducing optical fiber on the surface of the server body, the author designs and builds the ROTDR distributed optical fiber sensing system for temperature measurement in the computer room, realizing the integrated direct measurement. The system has the advantages of high precision, strong stability and fast response time, which provides a reliable theoretical basis for temperature safety monitoring and fault warning in the computer room.
