Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in detail:
Embodiment 1
As Fig. 1, a kind of monitoring water environment system, comprising:
Measuring tube 1, its lower port be provided with lighting device and in use this lower port be suitable for entirety and enter the water surface 2, upper portPlace establishes a camera head, and this camera head is suitable for taking the water surface image 2-1 in described measuring tube 1;
Video acquisition module, is connected and is suitable for collection image to be transformed to digital picture with described camera head;
With the image processing module that described video acquisition module is connected, this image processing module stores the first sample data, instituteState the gray value that the first sample data is suitable for recording 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;
Be located at the peripheral float for this measuring tube is vertically bubbled through the water column of described measuring tube, this float is dish type and fixingBe sheathed on described measuring tube, described screw comprises that Central Symmetry is distributed in three on described float; Described wireless telecommunicationsModule is connected with for according to the duty of the each screw of described remote control signal control, to control in real time described measuring tubeThe screw controller of the position on the described water surface;
Described image processing module is suitable for described digital picture to carry out gray scale processing, to obtain the ash of described water surface image 2-1Degree value, this gray value and the first sample data are compared and are drawn water quality situation.
Water quality detection principle is to utilize the gray value of the corresponding gray value sample of different quality and water surface image to be detectedCompare, image processing module stores each gray value sample of different quality, i.e. the first sample data.
Adopt MATLAB built-in function to carry out corresponding gray value processing to described water surface image 2-1, step is as follows:
I=imread (' image.jpg '); % opens pending picture (8 gray scales)
Imshow (I); % shows this picture
C=mean2 (I); The mean value of % computed image picture element matrix
Just can calculate the gray value of described water surface image 2-1 by mean2 function.
Table 1 is the average gray value of various water quality, i.e. the first sample data:
| Water sample type | Pure water | River | Swimming-pool water | Be 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 general general knowledge, the water quality quality of these water samples can be arranged like this: 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) moreHour, can think that its water quality is poorer, vice versa. Thereby in the time of water quality detection, can pass through the calculating to water body overall gray levelDraw corresponding water quality conclusion, can also pass through the more senior processing means such as sample extraction, neutral net, pattern-recognition, doTo detecting the more water quality index of refinement such as turbidity.
For example, if the gray scale of the water surface image 2-1 detecting is 85, show that the water quality of this water quality and river is suitable.

Also rotating shaft one end of stepper motor 8-3 can be fixed on to the lower surface, bottom of described measuring tube 1, support is coaxially solidDue to the upper surface, bottom of described sleeve pipe 8-1, in the time that stepper motor 8-3 rotates, because rotating shaft is fixed, can not rotate, machineSeat will rotate, and support drives sleeve pipe 8-1 to rotate around described measuring tube 1.
See Fig. 4, can also in described annular seal space 8-2, motor 8-4 be installed, described in the support of motor 8-4 is fixed onThe lower surface, bottom of measuring tube 1, and the center of this lower surface, bottom and the center of this support corresponding, coaxial,Rotating shaft 8-5 one end of described motor 8-4 is connected with the upper surface, bottom of described sleeve pipe 8-1, due to motor 8-4 rotationIn time, is difficult to control the angle of rotating, thus a spacing cross bar 8-6 is installed on the rotating shaft 8-5 of described motor 8-4, in instituteThe upper surface, bottom of 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 (One, the second gag lever post is a pair of, and the 3rd, the 4th gag lever post is a pair of) between, when described motor 8-4 rotates, drive described coverPipe 8-1 rotates around described measuring tube 1, and two pairs of gag lever posts define the anglec of rotation of motor 8-4.
See Fig. 5, specific works process, establishes described spacing cross bar 8-6 two ends in the second gag lever post 8-7b, the 3rd gag lever post, the through hole on through hole and sleeve pipe 8-1 on described measuring tube 1 coincide when at 8-7c the place, and described spacing cross bar 8-6 two ends are in firstWhen gag lever post 8-7a, the 4th gag lever post 8-7d place, the through hole on through hole and sleeve pipe 8-1 on described measuring tube 1 staggers each other, withPrevent that light from entering measuring tube 1.
In the time that camera head is prepared to take, motor 8-4 controls rotating shaft 8-5 and drives spacing cross bar 8-6 to rotate to the first limitWhen position bar 8-7a and the 4th gag lever post 8-7d place, motor 8-4 quits work, at this moment through hole and the sleeve pipe on described measuring tube 1Through hole on 8-1 staggers each other, and to prevent that extraneous light from entering described measuring tube 1, camera head is taken, take complete,Motor 8-4 reversion, when described spacing cross bar 8-6 rotates to the second gag lever post 8-7b and the 3rd gag lever post 8-7c place, described in makingThrough hole on through hole on measuring tube 1 and sleeve pipe 8-1 coincide, and makes current circulation.
In certain this scheme, gag lever post also can utilize stopper slot to substitute, described in the width of rebate of this stopper slot is greater thanSpacing cross bar 8-6.
Embodiment tetra-
On the basis of embodiment mono-to three, carry out the measurement of water level, this technical scheme is as follows:
In described measuring tube 1, also comprise float in pipe, in this pipe, float is the column structure with the center through hole of vertical setting,Described image mechanism is suitable for taking the water surface image in described center through hole, and in this pipe, float is suitable for the water surface in described measurementIn pipe 1, fluctuate; Water surface image 2-1 in managing by shooting in float makes the edge of this water surface image 2-1 more clear, justIn the area that extracts this water surface image 2-1.
Embodiment five
See Fig. 6, on the basis of embodiment mono-to three, the scheme of carrying out level measuring is as follows:
The upper port place of described measuring tube 1 is installed with a camera head, and outer being arranged with of described measuring tube 1 is suitable for making this surveyVertically bubble through the water column 2 float 3 of buret 1, and can make measuring tube 1 bubble through the water column by this float 3, without fixing in addition.
Described monitoring water environment system also comprises:
Flexible scale 4, one end is fixed on the bottom, and the wrap-up 5 that the other end and is suitable for this flexibility scale 4 of rolling is connected, shouldWrap-up 5 is fixed on the top of described measuring tube 1;
