Embodiment 1

[0048] like figure 1 As shown, a water quality monitoring system based on image recognition includes a water intake unit and a water quality monitoring unit.

[0049] The water intake unit includes a floating decanter 1, a water pump 2 and a water tank. An overflow plate 31 is provided in the middle of the water tank, and the overflow plate 31 divides the water tank into a buffer bin 32 and a photo taking bin 33 . The buffer bin 32 is provided with a water inlet 321 on the side wall far away from the overflow plate 31 , and the side wall far away from the overflow plate 31 is provided with a water outlet 331 on the side wall of the taking photo bin 33 , and the water pump 2 One end is connected to the floating decanter 1 through a pipeline, and the other end is connected to the water inlet 321 through a pipeline. A baffle 322 is provided in the middle of the buffer bin 32 , and a through hole 323 is provided in the lower part of the baffle 322 . The height of the baffle pla...

Embodiment 2

[0055] like image 3 Shown, a kind of water quality monitoring method based on image recognition, described monitoring method comprises the steps:

[0056] S1, taking water samples from the surface of the water body;

[0057] S2. Perform overflow treatment on the water sample;

[0058] S3, performing illumination and image acquisition on the water sample after the overflow treatment;

[0059] S4. Analyzing the collected water sample images to determine whether the water samples are polluted;

[0060] S5. When the water sample is polluted, an alarm is issued and an image of the polluted water body sample is displayed.

[0061] like Figure 4 As shown, the step S4 specifically includes the following steps:

[0062] S41. According to the water sample image, analyze and obtain the light intensity information of each pixel in the image;

[0063] S42. When the light source is arranged at the bottom, obtain the minimum light transmission intensity P2 according to the light inte...

Abstract

The invention discloses a water quality monitoring system and method based on image identification. The system comprises a water taking unit and a water quality monitoring unit. The water taking unitcomprises a floating type water taking device, a water suction pump and a water tank which are connected in sequence. An overflow plate is arranged in the water tank and divides the water tank into abuffer bin and an illumination taking bin, and the buffer bin is located on an upstream of the illumination taking bin. Due to adoption of the technical scheme, compared with the prior art, by using the system and the method of the invention, the overflow plate is arranged to inhibit fluctuations of a surface of a monitored water body so that definition of a water body image and accuracy of a detection result are improved, automation of water body surface pollution identification is realized, and identification work efficiency is higher, safer and reliable.

Description

technical field [0001] The invention relates to the technical field of water quality monitoring, in particular to a water quality monitoring system and monitoring method based on image recognition. Background technique [0002] With the rapid improvement of the country's environmental protection standards, monitoring whether there is sneak discharge or leakage of water surface pollution has become more and more important. Judgment of water surface pollution is a common measure for environmental protection in all walks of life. At present, there are mainly two methods for judging water surface pollution. One is to judge whether there is water surface pollution by observing the surface state of the water body such as the color of the water body and impurities. This judgment method has high work intensity and low work efficiency. Due to the influence of factors such as the difference in experience between them, the pollution situation cannot be judged objectively and accuratel...
