Description
Technical field
The utility model belongs to water quality inspection technique field, is specifically a kind of liquid transparency detection based on image procossing
Device.
Background technology
Transparency refers to the degree that water body can penetrate light, and being can with transparent scale (Sai Shi disks) into the water
Observable depth capacity is measured.It is an important indicator in water investigation, reflects the transmittancy of water body, water body
The research of transparency has practicality to hydro-environmental change, water body optical parameter, aquatic ecosystem and aquifer cultivation etc.
Value.The method of detection water transparency traditional at this stage is broadly divided into font method, Sai Shi disks method and light measurement transparency and surveys
Amount method.
Font method explanation：Font method be testing staff from the nozzle of diaphanometer vertically downward from, can just understand
The standard type Printing Marks for identifying its bottom when water-column be the water body transparency.Diaphanometer is a kind of length
33cm, internal diameter are the graduated glass infuser of tool of 2.5cm, and there is a polished glass piece at cylinder bottom, is printed on the letter press of standard above
Character.
Sai Shi disk method explanations：This is a kind of method of on-site measurement transparency.Sai Shi disks are that 30 centimetres of diameter, black and white are fifty-fifty
Disk, be submerged into water sample to be detected, depth of water during just can't see it represents transparency, equally with bentimeters table
Show its transparency.The depth that this method is surveyed is that white clear degree plate, scattering are equal with the scattering light of Sai Shi disk more than water columns
The result of weighing apparatus.
Light measurement diaphanometry explanation：Light measurement diaphanometry is also known as spectrophotometry.It is defined as：It is a branch of
Monochromatic collimated beam is after uniform, non-scatter solution propagates certain distance, the ratio between luminous energy stream and original luminous energy stream.It is mainly used for reality
Test room liquid transparency accurate measurement.The principle of light measurement diaphanometry be light that a light source distributes after prism,
Its light path changes, and becomes directional light.Then filtered by monochromator, generate monochromatic light.Detector, amplifier, note
Record instrument is used to measure luminous energy stream of the monochromatic collimated beam before and after by sample cell.
More than the method for traditional detection water transparency have the shortcomings that respective, the eyesight of the examined personnel of font method etc.
The intensity effect that subjective impact and illumination light are shone is larger, and (such as light intensity, lake surface reflect the main tested person environment of Sai Shi disk methods
The scattering of light, water body ambient enviroment light) and the eyesight etc. of tester be affected, the detection of light measurement diaphanometry

For the transparent tube body that organic glass makes, long 33cm, internal diameter 2.5cm.
In order to further clearly record the real-time pictures of liquid sample, in one preferred embodiment of the utility model,
The camera is 5,000,000 pixels.
Sample storage cavity 1 for the receiving of sample, for the concrete shape of sample storage cavity 1, can select cylindrical cavity,
Square cavity can also be selected, need to only meet the detection demand of sample transparency.The present embodiment has selected cylindrical cavity.
It is specifically described below exemplified by being detected to certain liquid sample transparency.
Before transparency detection is carried out, first sample storage cavity, detection pipe can be cleaned, specific cleaning process
For：Sample storage cavity is cleaned first, closes camera, threeway is opened, sample storage cavity is made to be communicated with liquid outlet, is inputted from inlet pure
Sample storage cavity is rinsed in water purification；Then detection pipe is cleaned, opens threeway, cleaning pipe is made to keep communicating with liquid outlet, it is defeated from rinse mouth
Enter pure water, rinse detection pipe；After sample storage cavity and detection pipe are all cleaned, threeway is opened, makes sample storage cavity and detection pipe
It communicates.
The detailed process being detected after cleaning is as follows.
(1) camera is opened, opens LED light, records the initial value of pressure sensor at this time, inlet is opened, to sample storage chamber
Sample to be detected is inputted in body, sample to be detected is entered by communicating pipe in detection pipe from sample storage cavity, and camera is adopted in real time
Image of the pattern after sample to be detected on set identifier disk calculates the resolution ratio of image, by the resolution ratio calculated with setting
The threshold value put is compared analysis.
(2) when the resolution ratio calculated is less than the threshold value set, threeway is closed, makes detector and sample storage cavity, detection
Device is remained off with liquid outlet, closes inlet, stops feed liquor, and the value that record pressure sensor collects will be remembered at this time
The value of record subtracts the initial value of pressure sensor record, and the value after subtracting is converted to transparency output.
(3) it is to be detected it is complete after, clean sample storage cavity and detection pipe again, open threeway, allow sample storage cavity, detection pipe,
Liquid outlet three keeps communicating, and opens inlet, rinse mouth, inputs pure water into sample storage cavity, detection pipe respectively, rinses storage
Sample cavity and detection pipe, it is flushed after waste water all from liquid outlet flow out.
Liquid transparency detection device provided by the utility model gathers sample to be detected by camera and enters in real time
The image of marker disc during detection pipe, and image resolution ratio is calculated, meanwhile, pressure sensor is also recorded in detection process
Pressure data, when resolution ratio is less than the threshold value set, close inlet and threeway, the value of record pressure sensor at this time,
The value finally recorded is subtracted into initial value, obtained value is then converted into transparence value, whole process fully achieves transparency inspection
The automation of survey process avoids the subjective impact of extraneous available light power and personal range estimation.
In the present solution, camera gathers the image information of marker disc, the pressure of the real-time acquisition testing pipe of pressure sensor in real time
Force value data once image resolution ratio reaches the threshold value of setting, the data of immediate record pressure sensor, and close threeway, from
And the speed of testing result and the accuracy of testing result can be greatly improved.
In the present solution, when the detection sample in detection pipe exceeds defined height, it will be from the overflow port above detection pipe
Outflow, general overflow port are arranged on the upper right quarter of detection pipe.
A kind of liquid transparency detection device provided by the utility model is described in detail above.Herein should
The principle and embodiment of the utility model is set forth with specific case, the explanation of above example is only intended to sides
Assistant solves the method and its core concept of the utility model.It should be pointed out that for those skilled in the art,
On the premise of the utility model principle is not departed from, can also to the utility model, some improvement and modification can also be carried out, these improvement
It is also fallen into modification in the protection domain of the utility model claims.
Above-described embodiment is used for explaining the utility model rather than limiting the utility model, in the utility model
Spirit and scope of the claims in, to any modifications and changes that the utility model is made, both fall within this practicality newly
The protection domain of type.
