Document Type and Number:
Japanese Patent JP7417342
Kind Code:
B2
Abstract:
The present invention discloses a train compartment vibration monitoring method and vibration signal feature library establishment and application methods. The non-intrusive train compartment vibration monitoring method only obtains vibration signals of a main measurement point in a train compartment during actual monitoring. The method accurately and truthfully reflects the relationship between the position of a vibration source and the phase offset and amplitude attenuation, can monitor the vibration of an unknown vibration source, and can identify the abnormal vibration to provide a basis for abnormal vibration processing. The method can realize the reconstruction of vibration source signals on the basis of only measuring the vibration signals of the main measurement point, so as to realize the real-time update of multiple variable vibration signal feature library; and the multivariable vibration signal feature library can provide a data basis for vibration signal optimization decomposition, vibration signal image identification, abnormal vibration signal identification, etc.
