[Abstract]:Fiber optic fiber. is called optical fiber. It is a commonly used cylindrical dielectric waveguide material. The optical wave propagating along the fiber is based on the theory of total reflection of light. The essence of optical fiber sensing technology is to detect the target by using light as the carrier of measurement through optical fiber communication. Fiber optic sensing technology is non-contact with the measured object, The measurement has the characteristics of high precision, high sensitivity, and fast reaction speed. In this paper, the temperature monitoring in different electrical equipment is studied and compared with the traditional temperature measurement method. The main contents of this paper are as follows: 1) comparing and studying the shortcomings of the existing temperature measurement techniques of various electrical equipment. (2) using optical fiber sensors to simulate the experimental operation, the main contents of this paper are as follows: 1) the main contents of this paper are as follows: 1. The whole design of optical fiber temperature measuring system is carried out in laboratory environment, and the accuracy of optical fiber in different electrical equipment is studied. Based on the determination of the main structure, the corresponding electrical equipment parameter acquisition module is integrated. Including data acquisition module, analysis module and abnormal processing detection module. (4) to test the optical fiber temperature measurement system in laboratory to improve its stability and accuracy, according to the measurement results of different parameters, The chip and material in the optical fiber temperature measurement system are replaced and selected, including optical fiber material, optical fiber sensor selection, parameter processing software adjustment. (5) the improved wavelet analysis noise reduction processing technology is put forward. It is used to test the whole system, install it in the electrical equipment, measure the parameters, and perfect the solution through the data result.
