The invention aims to provide a method for identifying personnel based on footstep vibration signals of narrow-way stairs. The method comprises the following steps: (1) collecting vibration signals; (2) vibration signal analysis; (3) establishing a personnel footstep vibration feature library; and (4) judging the characteristic parameters of the vibration signals of the personnel going upstairs and downstairs to obtain personnel information. Personnel footstep identity recognition is completed through vibration of the narrow-way stair structure with the stable installation foundation, and compared with recognition modes such as an induction card, a coded lock, fingerprint recognition and face recognition, active verification of personnel is not needed, and convenience, rapidness, safety and high efficiency are achieved. Compared with a flat ground footstep recognition technology, the narrow-way stairs are used for fixing the strides of the personnel, interference caused by unstable strides ...
