Water quality measurement system and method considering non-linear characteristics of electrical conductivity sensor

摘要

The present invention relates to a water quality measuring system and method in consideration of the non-linear characteristics of the electrical conductivity sensor, the sensor unit for measuring the electrical conductivity of water having non-linear characteristics; an AD converter that converts the electrical conductivity measurement value having a nonlinear characteristic applied from the sensor unit and outputs a digital voltage value; Generates electrical conductivity measurement information through an operation corresponding to a preset sensor cell constant value from a digital voltage value, and monitors the electrical conductivity measurement information in real time to generate an abnormal signal when the value of the electrical conductivity measurement information deviates from the set standard. control unit; and an IoT communication unit that transmits the abnormal signal to the previously linked manager terminal through wireless communication when receiving the abnormal signal from the control unit. According to the present invention as described above, by linearizing the measured value of the electrical conductivity sensor having non-linear characteristics, it is possible to measure water level, water temperature or electrical conductivity for water quality having non-linear characteristics, and an abnormality occurs by analyzing the calculated electrical conductivity In this case, by transmitting to the manager terminal through the IoT wireless communication network, a sudden change in water level, water temperature, or electrical conductivity can be provided to the manager in real time.
