이하 본 발명의 실시예를 첨부된 도면들을 참조하여 상세히 설명한다. 우선 각 도면의 구성요소들에 참조부호를 부가함에 있어서, 동일한 구성요소들에 대해서는 비록 다른 도면상에 표시되더라도 가능한 한 동일한 부호를 가지도록 하고 있음에 유의한다. 또한 본 발명을 설명함에 있어, 관련된 공지 구성 또는 기능에 대한 구체적인 설명이 당업자에게 자명하거나 본 발명의 요지를 흐릴 수 있다고 판단되는 경우에는 그 상세한 설명은 생략한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. First, when adding reference numerals to the components of each drawing, it is noted that the same components have the same reference numerals as possible even though they are displayed on different drawings. In addition, in describing the present invention, when it is determined that a detailed description of a related known configuration or function is obvious to those skilled in the art or may obscure the gist of the present invention, the detailed description will be omitted.

DC 계측데이터 저장 메모리 감소를 위한 분리 압축 방법은 DC의 계측 데이터를 기 설정된 기준에 따라 일반 데이터, 경고(warning) 데이터 및 결함(fault) 데이터을 생성한다. 여기서 DC는 AC와 달리 특성상 변화량이 많지 않다. The decompression method for reducing DC measurement data storage memory generates DC data, general data, warning data, and fault data according to preset criteria. Here, unlike AC, there is not much change in nature.

분리 압축 방법은 DC 기준값의 오프셋(offset)을 압축하여 상기 일반 데이터를 저장한다. 분리 압축 방법은 계측 값을 압축하여 DC 기준값의 5% 내지 10%로 설정된 상기 경고 데이터를 저장한다. 분리 압축 방법은 기존 형태 그대로 상기 결함 데이터를 저장한다.The separation compression method compresses the offset of the DC reference value to store the general data. The separation compression method compresses the measured value and stores the warning data set at 5% to 10% of the DC reference value. The separating compression method stores the defect data as it is in the existing form.
