基于硬件过采样技术的高精度直流断路器电量采集设计
High precision DC circuit breaker power collection design based on hardware oversampling technology
摘要
Abstract
In order to improve the accuracy of power collection for DC circuit breakers,this paper designs a data collection method based on the internal analog-to-digital converter of domestic microcontroller.This method adopts the oversampling technology of internal analog-to-digital converter of the microcontroller to achieve high-precision acquisition and conversion of analog signals,and implements power collection accuracy tests under different operating conditions.The experimental results show that,with the use of an internal analog-to-digital converter oversampling and filtering algorithm in the microcontroller,the digital quantity collected by the microcontroller remains stable,and the accuracy of the collected circuit breaker power can reach 1.5 levels.关键词
