Problems solved by technology

The turbidity data obtained by this estimation method is inaccurate, and the accuracy cannot reach
Moreover, there is sunlight interference in some environments. Sunlight shining into the water will further affect the accuracy and precision of turbidity detection, resulting in inaccurate turbidity data, which cannot be used for later reference.

Abstract

The invention provides a turbidity detector and a detection method. A circuit module and an optical module are connected with each other, the optical module is arranged at the first end of the shell and is detachably connected with the first end of the shell, and a receiving unit and a transmitting unit are respectively communicated with the outside of the shell through light guide columns. The transmitting unit transmits the detection light according to a detection control instruction, the receiving unit receives the detection light and transmits a received light signal to the circuit module,and the control unit is connected with the receiving unit and the transmitting unit separately through a data transmission processing unit, sends a detection control instruction to the transmitting unit, acquires the received optical signal through the receiving unit and calculates to obtain the water turbidity data. According to the present invention, the interference of sunlight to the sensorsis reduced by adopting a filter; by transmitting a square wave signal and processing the signal, the interference of the light with the same wavelength in the sunlight on the received signal is reduced; and by adopting a light receiving and emitting access with a certain angle, the light radiation range is expanded, and the detection accuracy of the sensor is improved.

Description

technical field [0001] The invention relates to the technical field of water quality turbidity detection, in particular to a turbidity detector and a detection method. Background technique [0002] Turbidity refers to the degree of obstruction of suspended matter in water when light passes through. Turbidity in water is generally caused by suspended solids, which are generally soil, sand particles, fine organic and inorganic substances, plankton, microorganisms and colloidal substances. The turbidity of water is not only related to the content of suspended substances in the water, but also related to their size, shape and refractive index. [0003] At present, turbidity generally uses a colorimeter or a spectrophotometer to measure the degree of attenuation of the transmitted light intensity caused by the obstruction of particles in the sample to estimate the data. The turbidity data obtained by this estimation method is inaccurate, and the accuracy cannot be achieved. Mo...
