Amplifying circuit-based optical property water quality monitoring system

The invention discloses an amplifying circuit-based optical property water quality monitoring system, which comprises a data collection terminal and a data monitoring terminal connected with the data collection terminal. The data collection terminal comprises a spectroradiometer, an underwater spectrometer, a water absorption/attenuation measurement instrument, a water body backward scattering measurement instrument, an ultraviolet-visible spectrophotometer, an analog-to-digital conversion circuit, an amplifying circuit, a controller module, a data transmission module and a power supply module. The data monitoring terminal comprises a memory module, a display module, a clock module, a processor module and a radio frequency identification module. The above multifunctional instruments are integrated as a whole, so that one single instrument is capable of detecting various parameters. Therefore, the system is convenient in application. The problems that due to the fact that the data processing operations of various instruments are mutually independent, the data of various instruments cannot be mutually checked and associated, the data processing efficiency is low and error-prone, and a large number of measured optical data cannot be processed can be avoided effectively.
