Method for monitoring water quality on line as well as device and system applied by method

Abstract

The invention discloses a method for monitoring water quality on line as well as a device and a system applied by the method, and relates to a water body detection technology. In order to solve the problem of inconvenience in detection in the prior art, the method comprises the step of finding out a characteristic peak and a height corresponding to an index by utilizing a curve formed by two kinds of spectral data so as to confirm the specific size of the index in a detected water body. The device is placed in a water body by using a buoy, and water body detection is carried out by using the method. On the basis of comprising the device, the system is also provided with a background server for deep processing. The system has the advantages that detection, communication, power supply and installation fixation are integrated, and site selection and arrangement of water quality monitoring points can be conveniently and effectively carried out. The water quality index is automatically analyzed by directly utilizing a water body fluorescence spectrum, an absorption spectrum and a self-adaptive algorithm, so that the effectiveness of a test index value is enhanced.

Description

technical field [0001] The invention relates to a method for monitoring water quality on-line and an application device and system thereof. Background technique [0002] In order to protect the safety of water resources, routine testing still adopts the method of sampling and submitting samples for inspection. Water samples are collected at water collection points, and then stored and transported to relevant testing institutions or laboratories. test. The whole process takes a long time, complicated steps, and poor real-time performance. The collection points and collection volume are limited by labor costs and cannot be widely deployed. These shortcomings are not conducive to understanding the overall water resource situation, and it is also impossible to monitor changes in sewage discharge in real time, so that it is impossible to provide timely feedback on the situation of illegal sewage discharge and dumping of garbage.

Problems solved by technology

The whole process takes a long time, the steps are complicated, and the real-time performance is poor. The collection points and collection volume are limited by labor costs and cannot be widely deployed.

These shortcomings are not conducive to understanding the overall water resources situation, and it is impossible to monitor the changes in the sewage discharge situation in real time, so that it is impossible to give timely feedback on the situation of illegal sewage discharge and dumping of garbage

[0003] Some existing water quality online testing equipment needs to install cabinets on the shore, pump water to the cabinets for pretreatment, and then test. Land leveling, infrastructure construction, and power supply line laying are required, which involves complex engineering construction processes.

[0004] Most of the existing water quality spectrometers use a single type of spectrum for water quality detection, which makes the measurable indicators limited, and the detection error caused by the mutual interference of multiple indicators in the water body is unavoidable
