Abstract
본 발명은 다채널 부하의 기동 감시장치에 관한 것으로서, 특히 다수의 부하가 동시에 기동시 각각의 부하에서 발생하는 과전류를 무인으로 정밀검출 후 이의 데이타를 내부 메모리에 저장하고, 기동점의 발생을 포착하여 디스플레이 시키도록하는 다채널 부하의 기동 감시장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a multi-channel load start monitoring device. In particular, an overcurrent generated from each load is unattended and precisely detected when a plurality of loads are simultaneously started. The present invention relates to a multi-channel load start monitoring device.
이를 위하여 부하의 기동 교류전류와 전압을 직류로 변환 및 리플성분을 제거하고 오차를 최소화하여 절대치로 변환하는 다수의 입력부, 선택적 조작에 따라 설정한 값에 대응되는 디지탈값의 기준전압을 발생하는 다수의 입력레벨 설정부, 상기 입력레벨 설정부의 출력신호를 아날로그신호로 전환하는 다수의 D/A변환기, 상기 다수의 입력부로부터 출력되는 신호를 증폭 및 안정화시키고 D/A변환기의 출력신호와 상호 비교하여 소정신호를 발생하는 다수의 고속비교부, 사이 고속비교부의 출력신호를 판독하여 이의 데이타 결과에 따라 디스플레이부를 구동하고 TTL신호를 출력시키는 마이콤을 포함하여서 된 것이다.To this end, a large number of inputs convert the starting AC current and voltage of the load into direct current, remove ripple components, and minimize the error to convert to absolute values, and generate a reference voltage of a digital value corresponding to a value set by selective operation. An input level setting unit of a plurality of D / A converters for converting an output signal of the input level setting unit into an analog signal, amplifying and stabilizing signals output from the plurality of input units, and comparing the output signals of the D / A converters with each other. It includes a high speed comparator for generating a predetermined signal, and a microcomputer for reading the output signal between the high speed comparator between the driving unit and outputting the TTL signal according to the data result.
