| description | The invention discloses a cable force calculation method and calculation device for an inhaul cable, and the method comprises the steps: collecting the time domain data of a target inhaul cable according to a preset time interval, and converting the time domain data into frequency domain data through employing a fast Fourier transform method, so as to construct a spectrogram; identifying all wavecrest data in the spectrogram by using a second derivative method; screening out first wave crest data exceeding a preset wave crest threshold value from all the wave crest data; determining second wave crest data in the first wave crest data according to a preset frequency interval; and calculating the cable force of the target inhaul cable based on the second wave crest data. According to the method, interference data can be automatically filtered from frequency domain data, the wave crest of the inhaul cable is recognized, the tension of the inhaul cable is accurately calculated, and then construction control and h |
