Abstract
본 발명은 온도특성 보상기능을 갖는 전류측정 장치에 관한 것이다.The present invention relates to a current measuring device having a temperature characteristic compensation function.
종래의 전류측정 장치는 주위온도 변화에 따른 전류센서의 출력전압 특성보상 기능이 없으므로 정확한 전력 요금계산 및 효율적인 전력관리가 이루어 질수 없을을 감안하여 본 발명은 전류공급회로, 미소전압이 유기되는 전류센서, 상기 전압신호를 증폭하는 전압변환 회로로 구성된 전류측정 회로부와 전류공급회로, 온도센서, 안정된 신호로 증폭하는 전압변환 회로로 구성된 온도측정 회로부와, 아날로그 신호를 2진데이타로 변환하는 아날로그/디지탈 변환회로부와 롬에 저장되어 있는 전류센서와 온도센서의 출력특성 룩-업 테이블의 값과 비교해서 전류센서에 의해서 측정된 전압 신호의 오차를 보상하는 마이컴으로 구성하여 정밀도가 높은 측정전류값을 이용하기 때문에 정확한 전력산출이 가능한다.Conventional current measuring device has no function of compensating the output voltage characteristics of the current sensor according to the change of ambient temperature, so the present invention is not limited to accurate power rate calculation and efficient power management. And a current measuring circuit part comprising a voltage converting circuit for amplifying the voltage signal, a current measuring circuit part comprising a current supply circuit, a temperature sensor, and a voltage converting circuit for amplifying a stable signal, and analog / digital converting an analog signal into binary data. It uses a high-precision measurement current value by compensating for the error of the voltage signal measured by the current sensor by comparing the output characteristic look-up table values of the current sensor and temperature sensor stored in the conversion circuit and ROM. Therefore, accurate power calculation is possible.
