Self-cleaning fine spectrum water body parameter measuring device and method based on turbidity correction

Abstract

The invention relates to a self-cleaning fine spectrum water body parameter measuring device and method based on turbidity correction, and aims to solve the technical problems that the accuracy of water body parameter monitoring based on a continuous fine spectrum analysis method at present is low, and sediment cleaning operation of a monitoring window is troublesome. The device comprises a shell, a water body accommodating pipe, a driving module, a drainage module, a detection module and a signal processing output module, the driving module comprises a driving assembly and a driving rod, a cleaning brush is arranged at the lower end of the driving rod, and the detection module comprises a turbidity scattering correction measuring unit and a continuous spectrum measuring unit which are arranged on the inner side face of the shell. The method comprises the following steps: 1, correcting a measurement result of a continuous spectrum measurement unit by adopting a plurality of standard solutions according to a measurement result of a turbidity scattering correction measurement unit to obtain a correction coefficient; 2, correcting the measurement result of the continuous spectrum measurement unit according to the correction coefficient; 3, starting a cleaning program; and 4, repeating the steps 2 and 3, and monitoring the water body parameters in real time.
