AI Technical Summary
Technical Problem
When monitoring switch current, the existing technology is limited by bandwidth and micro-periods, and the collected discrete data is prone to miss instantaneous current values, lose current characteristics, and lead to unsightly drawing of the current curve.
Method used
The triad B-spline fitting algorithm is used to differentiate the three-phase current data within the preset time range, and the current curve is fitted according to the difference, and the current data is fused or fitted separately under different conditions.
Benefits of technology
Through the fitting algorithm, the switch fault characteristics are retained, the smoothness and aesthetics of the current curve are improved, and the safety of equipment operation is enhanced.

Abstract
The embodiments of the present disclosure provide a current curve fitting method, device, equipment and storage medium, the method includes collecting discrete three-phase current data when the turnout is in action; subtracting the three-phase current data within a preset time range to obtain a difference, and fitting the current curve according to the difference; when the three groups of difference values are all less than the threshold, the corresponding three-phase current data are fused and then fitted; when two of the groups of difference values are greater than the threshold, the two-phase current data corresponding to the difference value less than the threshold are fused and then fitted, and the remaining one-phase current data is fitted separately; when the three groups of difference values are all greater than the threshold, the corresponding three-phase current data are fitted separately. It not only retains the fault characteristics of the turnout, but also ensures that the curve is smoother and more beautiful, effectively improving the safety of equipment operation.
