Technical Index and Test Method of Distributed Optical Fiber Temperature Measurement System for Mine

Based on the principle of temperature and positioning measurement of the distributed optical fiber temperature measurement system, the characteristics of the technical parameters such as the spatial resolution, the temperature measurement range, the accuracy of temperature measurement and positional resolution, the single channel test time and the fire warning function are analyzed in combination with the product status and the special situation of the coal mine. Technical requirements are suggested and reasonable testing and testing methods are developed.
