Fig. 1 is the structural schematic diagram of sedimentation detecting system in one embodiment of the invention；
Fig. 2 is the contrast schematic diagram of trisquare and standard ruler in this embodiment of the invention.
Specific implementation mode
The present invention will be further described with reference to the accompanying drawings.
The present invention proposes a kind of sedimentation detecting system, and Fig. 1 show the structure of the sedimentation detecting system in the present embodiment
Schematic diagram.The sedimentation detecting system includes benchmark liquid storage container 1, detection liquid storage container 2, stores up benchmark liquid storage container 1 and detection
Communicating pipe 3 that liquid container 2 is connected to, positioned at benchmark liquid storage container 1, detection liquid storage container 2 and testing liquid 4 in communicating pipe 3, clap
Take the photograph device 5.At least part of detection liquid storage container 2 is curved and is transparent；It is provided with scale in at least part,
The scale indicates its height of (i.e. the scale) position in the vertical direction.Filming apparatus 5 is located at detection liquid storage container 2
Outside, the relative position of liquid level and at least part intersection and scale for shooting testing liquid 4 are to be measured for obtaining
The liquid level of liquid 4.In order to facilitate detection, in the present embodiment, testing liquid 4 carries color, in order to which filming apparatus 5 determines
The liquid level of testing liquid 4.
Detection liquid storage container 2 is fixed on tested point, and the liquid level position of interior testing liquid 4 changes with the sedimentation of tested point
And the change in height occurs.
In the present embodiment, detection liquid storage container 2 is curved tube, and the detection liquid storage container 2 is semicircle shape curved tube；Filming apparatus
5 are located at the position of the center of circle double altitudes of the semicircle shape curved tube.
The sedimentation detecting system further includes trisquare 6, and above-mentioned scale is the scale of the trisquare 6.In the trisquare 6 in addition to scale
Part be it is transparent, be arranged detection liquid storage container 2 above-mentioned at least part on.In the present embodiment, the main body of trisquare 6 is adopted
It is constituted with transparent material；Trisquare is pasted onto in above-mentioned at least part of detection liquid storage container 2.It specifically, should in the present embodiment
Trisquare 6 is pasted onto the curved tube of detection liquid storage container 2 close to the side of filming apparatus 5.
Filming apparatus 5 has or is connected with communication module, is sent to intelligent image processing terminal 7 by the communication module
The information of shooting, intelligent image processing terminal 7 detect testing liquid liquid level in liquid storage container during occurring by comparing sedimentation
Variation of the position relative to liquid level in benchmark liquid storage container, you can calculate the settling amount of tested point.In the present invention, communication module
Can be wireless communication module or wire communication module.
The sedimentation detecting system further includes babinet 8, which is located in babinet 8.Babinet 8 has relief hole
9, when testing liquid overflows into babinet 8 from detection liquid storage container 2, to be discharged from relief hole 9.
Fig. 2 is the contrast schematic diagram of the trisquare 6 and standard ruler 601, for illustrating the trisquare 6 for sedimentation detecting system
When, the precision of filming apparatus shooting picture and the accuracy of finally obtained liquid level can be significantly improved.In view of semicircle
Trisquare is symmetrical about trunnion axis od, and 0≤θ is only discussed here<The case where pi/2.
Put vertical standard ruler vertically along gravity direction, wherein o points and c points are projected in the horizontal direction on semicircle trisquare
When, correspond to d points and b points on trisquare.Scale between standard ruler oc is also the same as between comprehending and projecting trisquare db.When liquid level arrives
When up to b points, the point on standard ruler corresponding to horizontal direction is c, and actual liquid level height is oc=h, on standard ruler
Scale marker height is h.B points are db=s relative to the actual range of d points on trisquare, but h is identified as on scale.
That is it intuitively sees, the scale marker on ruler is elongated on trisquare.
According to trigonometric function and arc length formula：
H=r × sin θ (formula 1)
S=r × θ (formula 2)
It is relative to the derivative of central angle θ：
Dh/d θ=r × cos θ (formula 3)
Ds/d θ=r (formula 4)
By formula 3 and formula 4, can obtain：
Ds/dh=1/cos θ (formula 5)
By formula 5, it can be deduced that draw a conclusion：
1) as θ=0, ds=dh.Differential on trisquare is equal to the differential on ruler.
2) work as θ>When 0, ds>dh.And θ angles are bigger, variation degree meetings of the trisquare differential ds relative to ruler differential dh
It is bigger.This illustrates that trisquare has enlarge-effect relative to ruler, and this enlarge-effect can be become with becoming larger for θ angles by formula 5
Change.
By being analyzed above it is found that the changing value that the variation of liquid level shows on trisquare is greater than standard ruler table
Reveal the changing value come.On this basis, which can preferably overcome the unit meter of the taken a picture marginal position of camera
Amount scale has the phenomenon that different degrees of compression than the unit dosage scale of center.
This hair can be understood and applied the above description of the embodiments is intended to facilitate those skilled in the art
It is bright.Person skilled in the art obviously easily can make various modifications to these embodiments, and described herein
General Principle is applied in other embodiment without having to go through creative labor.Therefore, the present invention is not limited to implementations here
Example, those skilled in the art's announcement according to the present invention, improvement and modification made without departing from the scope of the present invention all should be
Within protection scope of the present invention.
