The measurement accuracy affects the practical application value of optical fiber sensor measurement system. In order to improve the measurement accuracy of optical fiber sensor, the influence of ambient temperature on the measurement results of optical fiber sensor is analyzed in detail. Firstly, the current fiber optic sensor measurement accuracy estimation model is analyzed. It is found that there is a certain non-linear mapping relationship between the optical fiber sensor measurement accuracy and the ambient temperature. Then the data mining technique is used to fit the nonlinear mapping function between the optical fiber sensor measurement accuracy and the ambient temperature , Establish a fitting model between the two, and finally analyze the performance of the fitting model. The results show that the model can accurately reflect the relationship between the measurement accuracy of optical fiber sensors and ambient temperature, and the analysis results are helpful to improve the measurement accuracy of optical fiber sensors.
