The invention provides a data center distributed optical fiber sensing monitoring system which comprises at least one distributed optical fiber temperature measuring master computer and a monitoring server, wherein each temperature measuring master computer is connected with a temperature measuring optical fiber and connected with the monitoring server through a network; the temperature measuring optical fiber extends into a data center computer room and is laid back and forth on a front door and a backdoor of each cabinet; the optical Raman scattering effect and the optical time domain reflection measurement technology are utilized to measure spatial temperature distribution information in real time, so as to acquire the temperatures of a wind inlet and a wind outlet at every height of each cabinet and to realize accurate measurement to microenvironment of the data center. The temperature measuring master computer carries out data processing, uploads the data to the monitoring server temperature to perform data analysis, statistics, storage as well as corresponding control operation. The sensing monitoring system provided by the invention has strong resistance to electromagnetic field interference, can be used for continuously measuring temperature distribution along the fiber; moreover, the measuring distance is long, the sampling granularity is high, the precision is good, and the system is simple in structure and convenient to maintain.
Description
Technical field: [0001] The invention relates to the field of electricity, in particular to communication technology, in particular to a temperature monitoring system for a communication data room, and in particular to a distributed optical fiber sensor monitoring system for a data center. Background technique: [0002] A large number of cabinets are installed in the computer room of the data center for communication services. Since the working status of the server system in the cabinet changes rapidly, the heat generated by different cabinets in different regions is also different from time to time. In the prior art, sampling points are set in the hot and cold aisles in the computer room of the data center, and the temperature information is sent back to the computer room environment monitoring system through the electronic temperature sensor. When the computer room environment is overheated, an alarm can be given in time. Since the temperature of only a few sampling point...
