Integrated direct current power supply remote online monitoring method and system

Abstract

This invention relates to the field of DC power supply monitoring technology, and discloses an integrated remote online monitoring method and system for DC power supplies. The method includes collecting battery operating data and performing signal smoothing and noise reduction processing to obtain a basic battery impedance value; performing characteristic analysis based on the basic battery impedance value to determine impedance trend characteristics; if the impedance trend characteristics exceed a threshold, combining historical backtracking data and system load status to extract and judge the impedance deviation sequence, obtaining a health status assessment result; performing error fusion and deviation correction based on the health status assessment result to determine the remaining power data; generating a system status log based on the remaining power data, and updating power management parameters accordingly. This method can achieve dynamic capture of battery impedance changes and accurate correction of remaining power, significantly improving the monitoring reliability and adaptive management capability of the power supply system.
