Abstract

The application discloses a catenary guide height measurement error dynamic correction method, device, equipment and medium, which is applied to the field of catenary geometric parameter precision measurement. The method constructs a guide height error-distortion degree time sequence correlation model related to the guide height error by analyzing the three-dimensional distortion degree corresponding to the original pull-out value sequence, the vertical acceleration and the pitch angle rate, and then compensates and corrects the original guide height sequence, and the correction effect is also verified. The guide height error-distortion degree time sequence correlation model effectively utilizes the internal stability of the pull-out value, realizes accurate tracing and measurement of the guide height error, and the three-dimensional distortion degree strengthens the dynamic adaptability of the model, so that the model can intelligently adapt to the change of complex working conditions, and the robustness and reliability under different line conditions are significantly improved. The method provided by the application forms a closed loop of acquisition-correction-correction verification, and the reliability and accuracy of the catenary detection system are improved.
