Multispectral water quality analyzer

Abstract

The invention relates to a multispectral water quality analyzer. The analyzer is characterized in that: the analyzer comprises a water quality detection part, a water quality analysis part and a power supply module; the water quality detection part comprises a camera obscura, and a light source generation device, a container for containing a liquid to be detected and a color sensor which are positioned in the camera obscura, and white light emitted by the light source generation device irradiates the liquid to be detected and reflects the color of the liquid to the color sensor; and the water quality analysis part comprises a central processor module, and a liquid crystal display module, a clock module, a hand-held button module and a storage module which are connected with the central processor module, the central processor module which is connected with the color sensor receives the chroma value obtained through the detection of the color sensor, compares the chroma value with data in an experiment database and displays the result on a liquid crystal screen. The light source generation device projects the color of the liquid to the color sensor through irradiating the liquid by the white light, and the water quality analysis part converts the data into water quality parameters through the datum acquisition and the datum processing and determines the compound content in a reagent by detecting the chroma value obtained through the reflection, so the analyzer of the invention has the advantages of small occupied space of equipment, less apparatus, good determination interference resistance, low cost, and high metering precision.

Description

technical field [0001] The invention relates to a new multi-spectrum water quality analyzer, in particular to a new multi-spectrum water quality analyzer based on MSP430. Background technique [0002] At present, most of the water quality testing in the aquaculture industry adopts chemical analysis and visual detection methods, which are cumbersome to operate, low in measurement accuracy, single in measurement, poor in portability, and prone to secondary pollution caused by chemical reagents. The traditional aquaculture water quality testing work is mainly based on manual on-site sampling and laboratory instrument analysis. Although the analysis methods in the laboratory are complete, there are defects such as low monitoring frequency, large sampling error, scattered monitoring data, and inability to reflect pollution changes in time in laboratory testing, which is difficult to meet the needs of the government and enterprises for effective water environment management.

Problems solved by technology

[0004] Although there are some single or multi-parameter water quality analysis instruments in the currently published patents, even multi-parameter measuring instruments do not have specific water quality testing equipment for the detection of ammonia nitrogen and nitrite content.
