Title:
DISTRIBUTED OPTICAL FIBER TEMPERATURE MEASUREMENT DEVICE, AND PHOTOVOLTAIC PANEL TEMPERATURE MEASUREMENT SYSTEM AND METHOD
Document Type and Number:
WIPO Patent Application WO/2023/097582
Kind Code:
A1
Abstract:
A distributed optical fiber temperature measurement device, and a photovoltaic panel temperature measurement system and method. The distributed optical fiber temperature measurement device comprises a temperature measurement module and a temperature measurement optical fiber. The temperature measurement optical fiber comprises sensing optical fibers and isolation optical fibers which are arranged at intervals in a crossed mode. The sensing optical fibers are arranged in an optical fiber clamp to form temperature measurement sensing surfaces of temperature measurement points. The isolation optical fibers are arranged on the back of the optical fiber clamp to form an isolation optical fiber storage area. The spatial distance between the adjacent temperature measurement points is adjusted by releasing and storing the isolation optical fibers in the isolation optical fiber storage area. The temperature measurement module is connected to the sensing optical fibers so as to obtain the temperature of the temperature measurement points by using the sensing optical fibers, to form a temperature measurement sensing surface of a single temperature measurement point. The single temperature measurement point is subjected to temperature measurement. The environment temperature of the optical fiber clamp corresponding to the isolation optical fibers is measured by means of the isolation optical fiber, and the sensing optical fibers of the adjacent measurement points are optically isolated. By adjusting the length of the sensing optical fiber, the measurement sensitivity of the temperature measurement point can be adjusted, and the accuracy of temperature measurement is ensured.
