The measurement data of instrument 1 calculates the relative settlement amount of each monitoring point.
Contact hydrostatic level 1 is mounted on monitoring point relative to liquid before the sedimentation of liquid storage container 2 before first calculating sedimentation
Face is poor, then calculate sedimentation after sedimentation after liquid level it is poor；Liquid level difference before liquid level difference after sedimentation and sedimentation, which is subtracted each other, can obtain monitoring point phase
For the settling amount of liquid storage container 2；One monitoring point of reselection is as datum mark, by other monitoring points relative to liquid storage container 2
Settling amount of the settling amount with the datum mark relative to liquid storage container 2 subtract each other, other monitoring points can be obtained relative to the datum mark
Settling amount.
The present invention also provides the relative settlement monitoring methods based on above-mentioned relative settlement monitoring system, including following step
It is rapid:
S1. each contact hydrostatic level 1 is mounted on corresponding monitoring point, the cylinder 12 of each measuring point requires to pacify
In the range ability of cylinder 12, and connect the relative settlement monitoring system.
If the contact hydrostatic level 1 is h, the weight of the piston block 13 with the liquid level difference in the liquid storage container 2
Power is G, and the pulling force of the stay wire displacement sensor is T, and the cross-sectional area of the inner cavity 121 is S；The Hooke type elastic component 14
The reading of the stay wire displacement sensor 11 is a when not deformation；The coefficient of elasticity of the Hooke type elastic component 14 is k；Linker
The density of middle connection liquid is ρ, and the reading of stay wire displacement sensor 11 is x when measurement.
When piston block 13, which is in, to be stablized, it is known that, the hydraulic pressure difference active force that piston block 13 is subject to are as follows:
N=S ρ gh (1)
Active force of the Hooke type elastic component 14 to piston block 13 known to Hooke's law are as follows:
F=| a-x | k (2)
If in the inner cavity 121 without connection liquid and when piston block 13 is under equilibrium state, the stay wire displacement sensor
11 reading is a0。
Then as reading x > a of stay wire displacement sensor 110When, Hooke type elastic component 14 is pressurized, piston block 13 in inner cavity 121
Have when in equilibrium state:
G=F+N+T (3)
When the reading of stay wire displacement sensor 11 works as x≤a0When, 14 tension of Hooke type elastic component, piston block in inner cavity 121
13 have when being in equilibrium state:
N+T=F+G (4)
Pass through above-mentioned (1), (2), (3), (4) four formula, it is known that, work as x > a0When, the contact static level of monitoring point
The liquid level of instrument 1 and liquid storage container 2 is poor are as follows:
As x≤a0When, the contact hydrostatic level 1 of monitoring point and the liquid level of liquid storage container 2 are poor are as follows:
Therefore formula is selected according to the size of the reading x of the corresponding contact hydrostatic level 1 in each monitoring point before sedimentation
(5) or before (6) calculating sedimentation each monitoring point is poor relative to liquid level before the sedimentation of the liquid storage container 2.
Such as assume there are tri- monitoring points A, B, C, by settling the corresponding contact hydrostatic level 1 in first three monitoring point
Reading calculate separately out, the respectively h poor relative to liquid level before the sedimentation of the liquid storage container 2 that settle first three monitoring pointA0、
hB0And hC0。
S2. after settling, pass through liquid level according to each monitoring point collected data of corresponding contact hydrostatic level 1
It is poor relative to liquid level after the sedimentation of the liquid storage container 2 that poor calculation formula calculates separately each contact hydrostatic level 1.
Such as it is calculated after tri- monitoring points above-mentioned A, B, C settle by formula (5) or (6) relative to the liquid storage container
Liquid level difference is respectively h after 2 sedimentationA1、hB1And hC1。
S3. after before each monitoring point sedimentation computed above relative to the liquid level difference of liquid storage container 2, the two difference is calculated,
Settling amount of the monitoring point relative to liquid storage container 2, i.e. settling amount calculation formula can be calculated are as follows:
Δ h=h1-h0 (7)
Wherein, Δ h is settling amount of the monitoring point relative to the liquid storage container 2；The h0To settle the preceding monitoring point
Corresponding contact hydrostatic level 1 and the liquid level in the liquid storage container 2 are poor；The h1It is corresponding for the monitoring point after sedimentation
Contact hydrostatic level 1 and the liquid level in the liquid storage container 2 it is poor.
For monitoring point A, according to formula (7), the settling amount relative to liquid storage container 2 is Δ hA=hA1-hA0；Monitoring point
The settling amount relative to liquid storage container 2 of B and C similarly calculates to obtain Δ hB=hB1-hB0With Δ hC=hC1-hC0。
S4. above-mentioned calculated value is settling amount of the monitoring point relative to liquid storage container 2, is next calculated between monitoring point
Relative settlement amount.Point on the basis of a monitoring point is selected, the settling amount and the base by other monitoring points relative to liquid storage container 2
The settling amount relative to liquid storage container 2 subtracts each other on schedule, can obtain relative settlement amount of other monitoring points relative to the datum mark, it may be assumed that
Δ H=Δ hX-Δh0 (8)
Wherein, Δ h0Settling amount for the datum mark relative to the liquid storage container 2；ΔhXIt is opposite for other monitoring points
In the settling amount of the liquid storage container 2, Δ H is settling amount of other monitoring points relative to the datum mark.
Such as using above-mentioned monitoring point A as datum mark, according to formula (8), then monitoring point B is relative to the heavy of monitoring point A
Drop amount is Δ HBA=Δ hB-ΔhA, monitoring point c is Δ H relative to the settling amount of monitoring point ACA=Δ hC-ΔhA。
So far, relative settlement amount of each monitoring point relative to the datum mark is calculated by aforementioned four step, works as monitoring
When the value of the relative settlement amount of point is greater than 0, which sinks relative to benchmark；When the value of relative settlement amount is less than 0, the prison
Measuring point rises relative to benchmark.
Contact hydrostatic level of the present invention, relative settlement monitoring system and method other contents referring to existing
There is technology, details are not described herein.
The above described is only a preferred embodiment of the present invention, be not intended to limit the present invention in any form, therefore
