Zusammenfassung:According to one embodiment of the present invention, a water quality measurement system for a water distribution network includes: a residual chlorine measurement unit which senses residual chlorine concentration of water by using an indication electrode and a comparison electrode; and a communication unit which transmits information on the residual chlorine concentration to an external device. The residual chlorine measurement unit has a storage unit forming a storage space for storing water and a measurement module coming in contact with the water stored in the storage space to measure the residual chlorine concentration of the water. The measurement module has the indication electrode and the comparison electrode coming in contact with water. The comparison electrode forms a silver chloride (AgCl)-coated layer. The system further includes a control unit which controls the application of voltages to the measurement module. The control unit may apply an overvoltage (higher than a preset voltage) to the measurement module to restore the AgCl-coated layer lost by usage. The present invention enables a manager to manage the water distribution network more accurately and efficiently. 본 발명의 일 실시예에 따른 상수관망 수질 측정 시스템은 지시극과 비교극을 이용하여 상수의 잔류 염소 농도를 센싱하는 잔류 염소 측정부; 및 상기 잔류 염소 정보를 외부 장치로 송신하는 통신부;를 포함하며, 상기 잔류 염소 측정부는 상수가 저장되는 저장공간을 형성하는 저장부 및 상기 저장부에 저장된 상수와 접촉되어 상수의 잔류 염소 농도를 측정하는 측정 모듈을 구비하며, 상기 측정 모듈은 상수와 접촉되는 상기 지시극 및 상기 비교극을 구비하고, 상기 비교극은 염화은(AgCl) 코팅층을 형성하며, 상기 측정 모듈에 전압의 인가를 제어하는 제어부;를 더 포함하며, 상기 제어부는 사용에 의해 손실되는 상기 염화은 코팅층을 복원하도록, 기 설정된 전압 이상의 과전압을 상기 측정 모듈에 인가할 수 있다.
