Embodiment
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：
Measurement pipe 1, its lower port is provided with lighting device and the lower port enters upstream face 2 suitable for entirety when in use, on
Port sets a camera device, and the camera device is suitable to shoot the water surface image 2-1 in the measurement pipe 1；
Video acquisition module, is connected with the camera device suitable for collection image is transformed into digital picture；
The image processing module being connected with the video acquisition module, the image processing module is stored with first sample number
According to the first sample data are suitable to the gray value for recording various water quality；
What is be connected with described image processing module is used to receive remote control signal and exports the wireless telecommunications of water quality situation
Module；
Peripheral located at the measurement pipe is used to making the float that the measurement pipe is vertically bubbled through the water column, the float be dish type and
Fixed cover is in the measurement pipe, and the propeller includes three that Central Symmetry is distributed on the float；It is described wireless
Communication module is connected with the working condition for controlling each propeller according to the remote control signal, to control the survey in real time
The propeller control of position of the buret on the water surface；
Described image processing module is suitable to carry out gray proces to the digital picture, to obtain the water surface image 2-1
Gray value, the gray value and first sample data, which are compared, draws water quality situation.
Water quality detection principle is the gray value with water surface image to be detected using the corresponding gray value sample of different quality
It is compared, i.e. image processing module is stored with each gray value sample of different quality, i.e. first sample data.
Corresponding gray value processing is carried out to the water surface image 2-1 using MATLAB built-in functions, step is as follows：
I=imread(‘image.jpg’);% opens pending picture（8 gray scales）
imshow(I);% shows the picture
C=mean2(I);% calculates the average value of image pixel matrix
The gray value of the water surface image 2-1 can be just calculated by mean2 functions.
Table 1 is the average gray value of various water quality, 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>It is 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 poorer, and vice versa., can be by water body overall gray level thus in water quality detection
Corresponding water quality conclusion is calculated, can also be by the processing hands of the higher levels such as sample extraction, neutral net, pattern-recognition
Section, accomplishes to detect the water quality index that turbidity etc. is more refined.
If for example, the water surface image 2-1 detected gray scale is 85, showing that the water quality is suitable with the water quality of river.

8-1；Described sleeve pipe 8-1 and one is suitable to the rotating mechanism drive connection that driving sleeve pipe 8-1 is rotated around the measurement pipe 1, this turn
Motivation structure is controlled by a controller being connected with the camera device, in not filming surface image 2-1, controls the rotating machine
Structure drives sleeve pipe 8-1 to rotate so that the through hole on through hole and sleeve pipe 8-1 in the measurement pipe 1 coincide and is suitable for current circulation；
In filming surface image 2-1, control the rotating mechanism to drive sleeve pipe 8-1 to rotate so that through hole in the measurement pipe 1 and
Through hole on sleeve pipe 8-1 offsets one from another, to prevent extraneous light from entering the measurement pipe 1.
The embodiment that the rotating mechanism control sleeve pipe is rotated around the measurement pipe 1：
See Fig. 3, annular seal space 8-2 formed between the bottom lower surface of the measurement pipe 1 and sleeve pipe 8-1 bottom upper surface,
Annular seal space 8-2 is provided with a stepper motor 8-3 to play waterproof action in annular seal space 8-2, can by stepper motor 8-3
To set rotational angle, the through hole on through hole and sleeve pipe 8-1 in the measurement 1 is set to coincide or offset one from another（In through hole figure
It is not drawn into）, stepper motor 8-3 support is fixed on the bottom lower surface of the measurement pipe 1, and center and the institute of the support
The center for stating bottom lower surface is corresponding, i.e., coaxial, and rotating shaft one end of the stepper motor 8-3 is with described sleeve pipe 8-1's
Bottom upper surface is connected to drive sleeve pipe 8-1 to be rotated around the measurement pipe 1, and stepper motor 8-3 is by controller control.
Stepper motor 8-3 rotating shaft one end can also be fixed on the bottom lower surface of the measurement pipe 1, support is coaxially solid
Due to described sleeve pipe 8-1 bottom upper surface, when stepper motor 8-3 is rotated, because rotating shaft is fixed, it will not rotate, then machine
Seat will rotate, i.e., support drives sleeve pipe 8-1 to be rotated around the measurement pipe 1.
See Fig. 4, motor 8-4 can also be installed in the annular seal space 8-2, motor 8-4 support is fixed on described
The bottom lower surface of measurement pipe 1, and the center of the bottom lower surface and the center of the support are corresponding, i.e., it is coaxial,
Rotating shaft 8-5 one end of the motor 8-4 is connected with described sleeve pipe 8-1 bottom upper surface, because motor 8-4 is in rotation
When be difficult control rotate angle, so a spacing cross bar 8-6 is provided with the rotating shaft 8-5 of the motor 8-4, in institute
The bottom upper surface for stating sleeve pipe 8-1 is provided with two pairs of gag lever posts, and the spacing cross bar 8-6 is embedded in two pairs of gag lever posts（I.e.
First, the second gag lever post is a pair, and the three, the 4th gag lever posts are a pair）Between, when the motor 8-4 is rotated, drive the set
Pipe 8-1 rotates around the measurement pipe 1, and two pairs of gag lever posts define the motor 8-4 anglec of rotation.
Fig. 5, specific work process are seen, if the spacing cross bar 8-6 two ends are in the second gag lever post 8-7b, the 3rd gag lever post
When at 8-7c, the through hole on through hole and sleeve pipe 8-1 in the measurement pipe 1 coincide, and the spacing cross bar 8-6 two ends are in first
When at gag lever post 8-7a, the 4th gag lever post 8-7d, the through hole on through hole and sleeve pipe 8-1 in the measurement pipe 1 offsets one from another, with
Prevent light from entering measurement pipe 1.
When camera device prepares to shoot, motor 8-4 control rotating shafts 8-5 drives spacing cross bar 8-6 to rotate to the first limit
When at the bar 8-7a and the 4th gag lever post 8-7d of position, motor 8-4 is stopped, at this moment the through hole and sleeve pipe in the measurement pipe 1
Through hole on 8-1 is offset one from another, and to prevent extraneous light from entering the measurement pipe 1, camera device is shot, and shooting is finished,
Motor 8-4 is inverted, when the spacing cross bar 8-6 is rotated to the second gag lever post 8-7b and the 3rd gag lever post 8-7c, is made described
The through hole on through hole and sleeve pipe 8-1 in measurement pipe 1 coincide, and current is circulated.
Gag lever post can also be substituted using stopper slot in certain this scheme, and the width of rebate of the stopper slot is more than described
Spacing cross bar 8-6.
Example IV
On the basis of embodiment one to three, the measurement of water level is carried out, the technical scheme is as follows：
Also include the column that float in float in pipe, the pipe is the center through hole with vertical setting in the measurement pipe 1
