Green blooms Measurement System to be placed underwater having measurement element vertically spaced apart

The purpose of the present invention is to measure green bloom by reflecting the characteristic that the distribution height of green bloom changes depending on time. The present invention relates to a green bloom measuring system placed underwater and having vertically spaced measurement module units, the system comprising: the plurality of measurement module units (100) arranged vertically and spaced apart from each other in a hollow body (10) and each having a light source part (110) and a light receiving part (120); a light source control unit (200) controlling the operation of the light source part (110); an optical signal measuring unit (300) collecting and measuring signals generated by the light receiving part (120); and an optical signal analysis unit (400) converting the signals measured by the optical signal measuring unit (300) into green bloom concentration. 본 발명은 중공구조의 몸체부(10)에 상하 이격배치되며, 각각 광원부(110) 및 수광부(120)를 갖는 복수의 측정 모듈부(100); 상기 광원부(110)의 동작을 제어하는 광원 제어부(200); 상기 수광부(120)에서 발생한 신호를 수집 및 측정하는 광신호 측정부(300); 및 상기 광신호 측정부(300)에서 측정된 신호를 녹조 농도로 환산하는 광신호 분석부(400)를 포함하는 것을 특징으로 하는 상하 이격된 측정 모듈부를 갖는 수심형 녹조 측정시스템이다.
