Aircraft monitoring method and device based on vibration sensor

The invention discloses an aircraft monitoring method and device based on a vibration sensor, and the method comprises the steps: converting a vibration signal received by the vibration sensor from a time domain to a frequency domain, selecting a frequency corresponding to an amplitude peak value for sampling, and obtaining sampling data; sampling data matched with aircraft signal characteristics are selected to obtain time-frequency parameters of the vibration signals, and the shortest distance between the center frequency, the flight rate and the flight path of the aircraft and the vibration sensor is obtained through the time-frequency parameters so as to monitor the state of the aircraft. According to the method, the aircraft signal characteristics corresponding to the air traffic event are determined, and the corresponding signal data are screened and matched from the vibration signals received by the vibration sensor, so that the shortest distance of the center frequency, the flight rate and the flight
