Water quality automatic detection and analysis system and evaluation model construction method

Abstract

The invention discloses a water quality automatic detection and analysis system and an evaluation model construction method, a three-dimensional coordinate system is established according to the width of a water area, the water flow direction and the depth of the water area, and the water quality at the same position and corresponding to different depth nodes is detected from top to bottom; the buoy shell is driven to move in the width range of a water area by utilizing the opposite driving directions of the paddles, and the water quality of different depth nodes in the width range of the water area is detected in the vertical direction; blades of the two floating and sinking driving assemblies are adjusted to be located on the same side edge of the buoy shell, the unified driving direction of the blades is used for driving the buoy shell to move in the water flow direction, and the water quality of different depth nodes at different positions in the water flow direction is detected in the vertical direction; integrating the water quality of each detection point in a three-dimensional coordinate system, and constructing an evaluation model between the water quality of the same water area and the distances between the upstream and downstream, the water depth and the shoreside; by adjusting the water injection rate, the power strength required by floating and sinking of the water quality detection device is reduced.

Description

technical field [0001] The invention relates to the technical field of water quality detection, in particular to a water quality automatic detection and analysis system and an evaluation model construction method. Background technique [0002] With the development of society and people's attention to life and health, coupled with the increasing shortage and deterioration of water resources, the application of water quality monitoring systems has attracted much attention. With the gradual improvement and maturity of water quality monitoring technology, water quality monitoring technology has become an environmental management It is the main means for the department to monitor the water quality and water condition of the water body in real time. [0003] In conventional sampling and testing, when water quality parameters without water level are obtained by sedimentation, it is often realized by driving the forward and reverse rotation of the paddles by the power mechanism on t...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a water quality automatic detection and analysis system and evaluation model construction method to solve the problem that in the prior art, there is a large demand for the power mechanism, the operation of subsidence and floating is relatively difficult, the power mechanism is often damaged, and sampling detection cannot be used at the same time. One paddle moves forward, backward, left, right, up and down, because the position of water quality detection is relatively single, and the accuracy of water quality influencing factors of the constructed water quality assessment model is relatively low.
