Embodiment Construction
[0056] The invention provides a method for estimating the running speed of a high-speed rail train using speed scanning, which can realize the running speed estimation of a high-speed rail train only by using the data of a seismometer outside the isolated area. The present invention firstly generates a series of force function amplitude spectra for the high-speed train train structure parameters and preset train running speeds, and then calculates the cross-correlation function between the force function amplitude spectra at various speeds and the signal amplitude spectrum received by a single detector, Finally, the speed corresponding to the maximum value of the cross-correlation function is selected as the estimated value of the train running speed.
[0057] see figure 1 , a kind of high-speed rail running speed estimation method utilizing speed scanning of the present invention, comprises the following steps:
