Benefits of technology

This technology describes how accurately it controls electricity usage for electronic devices such as computers or smartphones during peak hours when they're at rest (when there may no use). By adjusting certain parameters like voltage levels, frequency settings, etc., these systems will reduce energy waste while still providing accurate performance over time.

Problems solved by technology

This patented technical problem addressed in the patented text relates to improving precision power usage monitoring devices' ability to accurately measure electrical current levels without being affected from outside temperatures. Current analyzers only work at specific temperatures due to their structure limitations and cannot account for variations caused by external environments like temperature differences. Additionally, existing models have difficulty predicting errors when changing certain parameters over large ranges with varying voltage values.

Abstract

The invention provides a precise power utilization regulation and control terminal calibration method, which comprises the steps of creating a thermal simulation model of a precise power utilization regulation and control terminal, and correcting the thermal simulation model by adopting change data of an error value of the precise power utilization regulation and control terminal along with temperature under different working conditions, the method comprises the following steps: acquiring data of variation of error values of related components of the accurate power utilization regulation and control terminal along with temperature under different working conditions, and constructing a self-learning model based on the data of variation of the error values of the related components along with the temperature to obtain a mapping relation between the error values of the related components and the temperature; and then temperature distribution data of the precise power utilization regulation and control terminal and temperature characteristics of related components under different working conditions are obtained, temperature compensation coefficients of the related components under different working conditions are determined, and temperature compensation calibration coefficients of the precise power utilization regulation and control terminal under different working conditions can be determined based on the temperature compensation coefficients. Therefore, the metering error of the accurate power utilization regulation and control terminal is reduced.
