Embodiment 1

[0030] Such as figure 1 , a water environment monitoring system, comprising:

[0031] The measuring tube 1 is provided with an illumination device at its lower port and is suitable for entering the water surface 2 as a whole when in use, and a camera device is arranged at the upper port, and the camera device is suitable for taking images of the water surface 2 in the measuring tube 1 -1;

[0032] A video capture module, connected to the camera device and adapted to convert the captured image into a digital image;

[0033] An image processing module connected to the video acquisition module, the image processing module stores first sample data, and the first sample data is suitable for recording gray values ​​of various water qualities;

[0034] A wireless communication module connected to the image processing module for receiving remote control signals and outputting water quality conditions;

[0035] A float arranged on the periphery of the measuring tube is used to make ...

Embodiment 2

[0048] On the basis of Embodiment 1, in order to avoid the influence of external light on the water surface image 2-1, the camera device is sealed and connected to the upper port, and the inner wall of the measuring tube 1 is provided with a black coating suitable for absorbing light.

Embodiment 3

[0050] See figure 2 , further, on the basis of Embodiment 2, in order to further avoid the influence of underwater light on the shooting, to improve the accuracy of the brightness and chromaticity of the captured water surface image 2-1, the measuring tube 1 is located below the water surface 2 A plurality of through holes are distributed on the pipe wall, and the bottom end of the measuring pipe 1 is closed; a sleeve 8-1 with through holes is sleeved on the pipe body below the water surface 2; the sleeve 8-1 It is connected with a rotating mechanism suitable for driving the casing 8-1 to rotate around the measuring tube 1. The rotating mechanism is controlled by a controller connected to the camera device. When the water surface image 2-1 is not taken, Control the rotating mechanism to drive the casing 8-1 to rotate so that the through hole on the measuring tube 1 matches the through hole on the casing 8-1 so as to be suitable for water flow; when shooting the water surface ...

Abstract

A water environment monitoring system comprises a measure pipe, a video acquisition module, an image processing module, a wireless communication module and a floater; the lower end port of the measure pipe is suitable for penetrating a water surface, and an imaging apparatus is arranged exactly above the upper end port of the measure pipe and is suitable for shooting water surface images in the measure pipe; the video acquisition module is connected with the imaging apparatus and is suitable for transforming the acquired image into a data image; the image processing module is connected with the video acquisition module, and stores first sample data recording the gray values of various water quality; the wireless communication module is connected with the image processing module and is used to receive a remote control signal and output the water quality status; the floater is arranged at the periphery of the measure pipe and is used to enable the measure pipe to vertically float on the water surface, and the floater is provided with at least one propeller for controlling the position of the measure pipe on the water surface; and the image processing module is suitable for performing gray processing on the data image to obtain the gray value, and the water quality status is obtained through comparison between the gray value and the first sample data.

Description

technical field [0001] The invention relates to the field of electronic measurement, in particular to an image visual processing technology to realize a water level and water quality monitoring device. Background technique [0002] The existing water level monitoring devices can only detect the water level alone, but cannot detect the water quality, and need to use another water quality monitoring device to realize it. How to realize the simultaneous measurement of water level and water quality is a technical problem in this field. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a water environment monitoring system suitable for water quality measurement. The water environment monitoring system uses the principle of grayscale detection to monitor water quality, that is, grayscale processing is performed on the captured water surface image to obtain the water surface image. The gray value of the water quality can ...
