Title:
MEASUREMENT CORRECTION METHOD AND APPARATUS FOR SENSOR, AND SERVER POWER SUPPLY
Document Type and Number:
WIPO Patent Application WO/2023/010790
Kind Code:
A1
Abstract:
A measurement correction method and apparatus for a sensor, and a server power supply. The method is applied to a sensor comprising a shunt resistor and a differential amplifier, and comprises: performing compensation verification on the sensor in advance to obtain a compensation coefficient of the sensor (step S1); obtaining a voltage signal output by the sensor (step S2); and correcting the voltage signal according to an error value of the shunt resistor and the compensation coefficient to obtain a voltage correction signal for use in system optimization management (step S3).
