A dual optical path water environment online measurement device based on spectral measurement technology

Abstract

The invention discloses an online dual-light-path water environment measurement device based on spectral measurement technology. The online dual-light-path water environment measurement device comprises a sealing shell, the shell is internally provided with a detection optical unit and a signal processing unit, and the middle of the shell is provided with a detection pool; a light source control panel controls a light source to work, and the light source emits ultraviolet-visible light; the ultraviolet-visible light is changed into parallel light after passing through a first lens; the parallel light is divided into two paths after passing through a semi-permeable semi-reflective mirror, one path of light is focused by a second lens after passing through light windows of the detection pool and then transmitted to an acquisition module through optical fibers and is used for testing a water sample to be tested, and the other path of light serving as reference signals of light source energy change is received by a photoelectric detector and then transmitted to a control and signal processing module. The online dual-light-path water environment measurement device has the advantages that solar energy is adopted for power supply, long-term operation can be achieved, a light window cleaning system is adopted, and precision of measured data can be guaranteed.

Description

technical field [0001] The patent of the present invention relates to the field of online monitoring of water body environmental pollution, in particular to the field of environmental optical monitoring technology, specifically a dual optical path water body environment online measurement device based on spectral measurement technology. Background technique [0002] In recent years, with the rapid development of my country's national economy, domestic environmental pollution has become increasingly serious. Among them, water pollution has been very prominent. The pollutants entering the water body will cause serious harm to the water body environment, aquatic animals and plants, and the presence of such pollutants in large quantities in drinking water will cause harm to human health. At present, the traditional detection methods for various pollutants in water mainly rely on chemical reagent methods. Traditional methods are mostly based on on-site sampling and laboratory a...

AI Technical Summary

Problems solved by technology

At present, domestic instruments that use spectroscopy to detect some pollutants in water bodies mostly use a single light source and a single measurement parameter.

Compared with western developed countries, my country's water quality environment detection and sensor technology are generally backward, and there is a lack of sensor analysis instruments with independent intellectual property rights that are reasonably priced and can achieve comprehensive, real-time, fast, accurate multi-parameter simultaneous detection. Seriously restricted the monitoring and control of the water quality environment

[0003] In addition, existing spectroscopic instruments for detecting some pollutants in water generally use manual operations. If you want to measure pollutants at a certain location and a certain depth, you need to manually go to the measurement point to measure, which is not only time-consuming and laborious , and sometimes it is very dangerous, such as somewhere in the ocean with harsh environment, which often poses a threat to personal safety; and it cannot guarantee long-term real-time measurement
