Turbidity sensor and water body turbidity on-line detection method

Abstract

The invention discloses a turbidity sensor and a water body turbidity on-line detection method. The turbidity sensor is of a special structure; the phenomena that the turbidity detection accuracy is influenced by attaching pollutants in a water body on a transmitting lens is possibly avoided; the condensation water mist on the transmitting lens is prevented by virtue of heating so as to eliminate the influence of the mist of the transmitting lens on detection; scattered light of the water body is acquired by an annular photovoltaic conversion device in 360 degrees, so that the effective received quantity of the scattered light is increased to the maximum extent; and the signal of an operation amplifying device is not needed to be amplified to guarantee the stability and reliability of the turbidity sensor. By utilizing the water body turbidity on-line detection method of the turbidity sensor, output voltage values, acquired for many times of a photovoltaic conversion device, are used and a processing mode that the average value is taken is adopted; modes of heating and light control are combined during the detection process every time, so that the detection error caused by the mist of the transmitting lens and the unstable light sources is eliminated, and the turbidity detection accuracy is further guaranteed.

Description

technical field [0001] The invention belongs to the technical field of electronic information, and in particular relates to a turbidity sensor and an online detection method for water turbidity. Background technique [0002] With the improvement of people's living standards and the continuous deepening of research on the relationship between drinking water and health, people's requirements for drinking water quality are also increasing. Turbidity is a characteristic parameter of the optical properties of water. It is not only one of the important indicators to measure the goodness of water quality, but also an important basis for evaluating the effect of water treatment. Therefore, the online detection of water turbidity has very important practical significance. [0003] At present, the turbidity of water can usually be detected by the scattering method. The detection principle of the scattering method is to use a light source to inject a beam of incident light with a fixed...
