Summary:The invention discloses an intelligent spectrum demodulation method of a micro-nano optical fiber sensor, which belongs to the technical field of optical fiber sensing, and comprises the following steps of: 1, outputting a broadband interference spectrum by a micro-nano optical fiber sensor system under different environment parameters; 2, adopting a few-spectrum sampling point technology (the sampling rate is lower than the Nyquist sampling rate) to collect interference spectrum data sets under different environment parameters; 3, extracting potential features of the interference spectrum data set by using an artificial neural network, training a model, and mapping the potential features to corresponding sensing quantities; the demodulation method of the traditional micro-nano optical fiber sensor is improved from two aspects of reducing the spectrum acquisition rate and intelligently demodulating, and the bottleneck of the measurement speed can be broken through under the condition that the measurement prec
