Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment the present invention is described in detail:
Embodiment 1
Such as Fig. 1, a kind of monitoring water environment system, including:
Measure pipe 1, its lower port be provided with illuminator and in use this lower port be suitable to overall enter the water surface 2, upper port
Place sets a camera head, and this camera head is suitable to the water surface image 2-1 shooting in described measurement pipe 1；
Video acquisition module, is connected with described camera head and is suitable to collection image is transformed to digital picture；
The image processing module being connected with described video acquisition module, this image processing module storage has the first sample data, institute
State the first sample data and be suitable to record the gray value of various water quality；
Be connected with described image processing module for receiving remote control signal and export the wireless communication module of water quality situation；
Being located at the peripheral for the float making this measurement pipe vertically bubble through the water column of described measurement pipe, this float is dish type and fixing
Being sheathed on described measurement pipe, described propeller includes three that centrosymmetry is distributed on described float；Described wireless telecommunications
Module connects the duty having for controlling each propeller according to described remote control signal, to control described measurement pipe in real time
The propeller control of the position on the described water surface；
Described image processing module is suitable to described digital picture is carried out gray proces, to obtain the ash of described water surface image 2-1
Angle value, this gray value and the first sample data are compared and are drawn water quality situation.
Water quality detection principle is the gray value utilizing different quality corresponding gray value sample with water surface image to be detected
Compare, i.e. image processing module storage has each gray value sample of different quality, the i.e. first sample data.
Using MATLAB built-in function that described water surface image 2-1 is carried out corresponding gray value process, step is as follows:
I=imread(‘image.jpg’);% opens pending picture (8 gray scales)
imshow(I);% shows this picture
C=mean2(I);% calculates the meansigma methods of image pixel matrix
The gray value of described water surface image 2-1 just can be calculated by mean2 function.
Table 1 is the average gray value of various water quality, the i.e. first sample data:
| Water sample type | Pure water | River | Swimming-pool water | It is mixed with the water of mud |
| Average gray value | 132 | 85 | 89 | 67 |
| Water sample type | By the water of dye discoloration | Prepared Chinese ink water | Industrial wastewater | Green tea water |
| Average gray value | 37 | 21 | 23 | 90 |
According to common sense, the water quality quality of these water samples may be arranged such that: pure water > green tea water > swimming-pool water > river
> be mixed with the water of mud > by the water of dye discoloration > industrial wastewater ≈ prepared Chinese ink water, when water body sampled images gray value (brightness value) more
Hour, it is believed that its water quality is the poorest, and vice versa.Thus when water quality detection, can be by the calculating to water body overall gray level
Draw corresponding water quality conclusion, it is also possible to by the process means of the higher levels such as sample extraction, neutral net, pattern recognition, do
The water quality index more refined to detection turbidity etc..
Such as, if the gray scale of the water surface image 2-1 detected is 85, then show that this water quality is suitable with the water quality of river.

The upper surface, bottom stating sleeve pipe 8-1 is provided with two pairs of gag lever posts, and described spacing cross bar 8-6 is embedded in described two pairs of gag lever posts (i.e.
One, the second gag lever post is a pair, and the three, the 4th gag lever posts are a pair) between, when described motor 8-4 rotates, drive described set
Pipe 8-1 rotates around described measurement pipe 1, and two pairs of gag lever posts define the anglec of rotation of motor 8-4.
See Fig. 5, specific works process, if described spacing cross bar 8-6 two ends are in the second gag lever post 8-7b, the 3rd gag lever post
Time at 8-7c, the through hole on described measurement pipe 1 and the through hole on sleeve pipe 8-1 coincide, and described spacing cross bar 8-6 two ends are in first
Time at gag lever post 8-7a, the 4th gag lever post 8-7d, the through hole on described measurement pipe 1 and the through hole on sleeve pipe 8-1 offset one from another, with
Prevent light from entering and measure pipe 1.
When camera head prepares shooting, motor 8-4 controls rotating shaft 8-5 and drives spacing cross bar 8-6 to rotate to the first limit
Time at the bar 8-7a and the 4th gag lever post 8-7d of position, motor 8-4 quits work, the through hole on the most described measurement pipe 1 and sleeve pipe
Through hole on 8-1 offsets one from another, and to prevent extraneous light from entering described measurement pipe 1, camera head shoots, and shoots complete,
Motor 8-4 inverts, and when described spacing cross bar 8-6 rotates to the second gag lever post 8-7b and the 3rd gag lever post 8-7c, makes described
Measure the through hole on pipe 1 and the through hole on sleeve pipe 8-1 coincide, make current circulate.
