Water quality monitoring system and method based on cloud platform

Abstract

The invention relates to a water quality monitoring system based on a cloud platform. The water quality monitoring system comprises a sampling terminal and the cloud platform; the sampling terminal comprises an immersion type probe, a light source, a spectrograph and an upper computer, and the immersion type probe comprises a slit for accommodating a water sample, a reflecting mirror and an optical fiber interface; during working, ultraviolet visible light generated by the light source passes through the water sample in the slit of the probe through an optical fiber, is reflected by the reflecting mirror and then passes through the water sample again, and is transmitted to the spectrograph through the optical fiber to obtain a water sample spectrum; and a water quality index and harmful substance spectrum prediction model is established on the upper computer. Spectral data of multiple sampling points are uploaded to a unified cloud platform through the upper computer, the data of the multiple sampling points are processed on the cloud platform according to the data migration theory, and correction of parameters of a water quality prediction model of the upper computer is achieved. According to the invention, the model is corrected by using the multi-sampling-point data on the cloud platform based on the data migration principle, and the prediction model which is more accurate than that based on single-sampling-point data is provided by using the big data advantage on the cloud platform.

Description

technical field [0001] The invention belongs to the field of ecological and environmental protection monitoring, and in particular relates to a water quality monitoring system and method based on a cloud platform. Background technique [0002] Water resources are an important basis for human survival. With the development of human activities and the development of nature, the pollution of water resources is very serious. Monitoring water quality is an important prerequisite for water pollution control. Compared with the national standard method of water quality testing, the use of spectroscopy has the advantages of saving time, effort, and low cost. It has great application value in occasions where accurate acquisition of water quality parameters is not required. [0003] Existing water quality monitoring systems using spectroscopic methods need to extract water samples into cuvettes, collect spectral data of the water samples through spectrometers, and use regression models...

Problems solved by technology

Since the pumping device requires additional power supply and the pipeline needs to be cleaned frequently, in practical application, the deployment requirements are high and the process is relatively complicated

[0004] Existing prediction models based on single sampling point data samples cannot guarantee data completeness, and it is difficult to ensure that the modeled data set has the same probability distribution as the full data set, resulting in a large systematic error in the actual model
