Abstract

The invention discloses a dynamic correction method, device and equipment for a contact network conductor height measurement error and a medium, and is applied to the field of precision measurement of geometric parameters of a contact network. According to the method, the three-dimensional distortion degree corresponding to the original pull-out value sequence is analyzed, the three-dimensional distortion degree, the vertical acceleration and the pitch angle rate jointly construct a height guide error-distortion degree time sequence correlation model related to the height guide error, then the original height guide sequence is compensated and corrected, and the correction effect is verified. The guide height error-distortion degree time sequence correlation model effectively utilizes the internal stability of a pull-out value, and accurate traceability and measurement of the guide height error are realized; the dynamic adaptive capacity of the model is enhanced through the three-dimensional distortion degree, so that the model can intelligently adapt to changes of complex working conditions, and the robustness and reliability under different line conditions are remarkably improved; according to the method provided by the invention, an acquisition-correction-correction verification closed loop is formed, and the credibility and the accuracy of the contact network detection system are improved.
