Zusammenfassung: | The invention discloses a quality control method for wind speed observation data along a high-speed rail line, which comprises the following steps of: after acquiring wind measurement data along the high-speed rail and performing basic quality control, selecting continuous time period data without an error value, and dividing the continuous time period data into a modeling sequence and a test sequence; performing phase space reconstruction on the wind speed sequence by using a CC method according to a phase space reconstruction theory, selecting a prediction center phase point as a reference phase point according to the reconstructed phase space, and fitting a prediction equation by using an improved first-order local area linearity; setting an error minimization objective function according to a weighted least square method, and a prediction value is obtained through calculation in combination with a prediction equation; moving the modeling sequence backwards for a time point, and repeating the steps to cont |
