Research on Self-calibration Algorithms Based on Optical Fiber Distributed Sensing Technology

In recent years, distributed optical fiber temperature measurement system has been widely used in industrial safety field. In this paper, the principle of distributed optical fiber temperature measurement system is introduced and the system performance is tested. The design and development of self-calibration system without real-time temperature compensation is carried out. The measurement accuracy of the system is improved. The distributed optical fiber temperature measurement system with low power consumption and high performance has been applied in the goaf and cable temperature field of coal mine, which provides a favorable detection method for the safety detection of coal mine underground.
