Embodiment Construction

[0039] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0040] The main implementation idea of ​​the present invention is: before using the water quality detection device to detect, firstly calibrate and calibrate the water quality detection device; The strong signal and the water temperature of the detected water sample, and then the MCU uses the correlation algorithm to analyze the detected original light intensity signal and water temperature, and obtains the detection results of TOC, COD, chromaticity and turbidity of the detected water sample; finally, the The test results are sent out.

[0041] The following will first introduce this water qualit...

Abstract

The invention is applicable to the technical field of multispectral detection and provides a water quality detection device and a water quality detection method. The water quality detection device comprises a plurality of monochromatic LED light sources, photoelectric detectors in one-to-one correspondence with the monochromatic LED light sources, an MCU and a temperature sensor, wherein the photoelectric detectors and the temperature sensor are connected with the MCU, the MCU is connected with the monochromatic LED light sources, the photoelectric detectors are used for detecting original light intensity signals emitted by every monochromatic LED light source and penetrating a detected water sample and sending the light intensity signals to the MCU, the temperature sensor is used for detecting the temperature of the detected water sample and sending the temperature of the detected water sample to the MCU, and the MCU is used for processing the received original light intensity signals and the temperature of the detected water sample so as to obtain water quality parameter detection indexes of the detected water sample. The water quality detection device is low in cost and can achieve real-time online detection by being mounted in a household water purifier.

Description

technical field [0001] The invention belongs to the technical field of multispectral detection, and in particular relates to a water quality detection device and a detection method thereof. Background technique [0002] Water is the source of life. As the problem of water pollution becomes more and more serious, people pay more and more attention to the safety of daily drinking water. Therefore more and more families have installed household reverse osmosis water purifiers. However, there is currently no effective method to evaluate the purification effect of the water produced by the water purifier. This brings about a problem that consumers cannot effectively evaluate the purification effect of the water purifier, and cannot accurately judge when the filter element needs to be replaced. [0003] At present, some high-end water purifiers are equipped with water quality TDS (Total dissolved solids) detectors to evaluate the water purification effect. However, the TDS indi...
