A scheme is proposed when it comes to identification of area intrusion events, from indicators detected by an ultra-weak fiber Bragg grating array in a subway tunnel. The spectral subtraction and also the root mean square of this power spectral thickness tend to be combined to draw out occasion signals. Your local characteristics-scale decomposition while the multi-scale permutation entropy are utilized consequently for function extraction, which can enhance the event recognition
