The utility model content
The purpose of the utility model promptly is to overcome the deficiency of prior art, provides a kind of measuring accuracy high, and temperature is floated little, the static settlement monitoring system based on the differential transformer type displacement meter that the life-span is long.
The purpose of the utility model realizes through following technical scheme:
A kind of long-acting static Chen Jiang ∕ flexiblity monitor system, it comprises a plurality of pick-up units 1, pick-up unit 1 is by liquid storing barrel 2, differential transformer type displacement meter 3, connecting link 4 is formed with cursory 5; Be communicated with through flexible pipe 6 between the liquid storing barrel 2, liquid storing barrel 2 is provided with differential transformer type displacement meter 3, and liquid storing barrel 2 inside are filled with liquid 7, is suspended with cursory 5, cursory 5 in the liquid 7 and is connected with differential transformer type displacement meter 3 through vertical connecting link 4; Pick-up unit 1 is connected with acquisition system 8 through lead.
Communication module is GPRS communication module or wire communication module.
Supply module connects accumulator by solar panel and forms.
The advantage of the utility model is: use the differential transformer type displacement meter, and the influence that this displacement meter is not shaken, measuring accuracy is high; Temperature drift is little, is adapted at the open area long-term work, is contactless mode of operation; Can not produce frictional property and destroy, the life-span is long, and cost is low.

Embodiment
Below in conjunction with accompanying drawing the utility model is further specified, the protection domain of the utility model is not limited to the following stated.
As depicted in figs. 1 and 2, a kind of long-acting static Chen Jiang ∕ flexiblity monitor system, it comprises a plurality of pick-up units 1, pick-up unit 1 is by liquid storing barrel 2, differential transformer type displacement meter 3, connecting link 4 is formed with cursory 5; Be communicated with through flexible pipe 6 between the liquid storing barrel 2, liquid storing barrel 2 is provided with differential transformer type displacement meter 3, and liquid storing barrel 2 inside are filled with liquid 7, is suspended with cursory 5, cursory 5 in the liquid 7 and is connected with differential transformer type displacement meter 3 through vertical connecting link 4; Pick-up unit 1 is connected with acquisition system 8 through lead.
Liquid 7 is pure water, and when the temperature of system's environment of living in during in subzero, liquid 7 is for being mixed with the pure water of anti freezing solution; Liquid 7 can also be 0.05% ~ 0.1% copper-bath for concentration; Copper sulphate does not have corrosivity, and has advantages of good anticorrosion performance, and effectively algae grows.
When the temperature of system's environment of living in was higher, in order to prevent water evaporates, being coated with thickness on the liquid level of liquid 10 was 1 ~ 2mm, and viscosity is the silicone oil or the paraffin of 5 ~ 10 lis of silks, and less viscosity can guarantee that the balance of liquid level is unaffected.
As shown in Figure 3, acquisition system 8 is by metering circuit, central processing unit, and communication module, supply module and server are formed; Metering circuit is connected with central processing unit, and central processing unit is connected with communication module, and communication module is connected with server, and supply module is connected with central processing unit.
Communication module is GPRS communication module or wire communication module, and supply module connects accumulator by solar panel and forms.
The principle of work of the utility model is following:
Select a motionless point as benchmark in measure field, at reference point 9 installation and measuring devices 1, the installation and measuring device 1 in the measured point, all pick-up units 1 connect through flexible pipe 6.Liquid level when sedimentation is sent in the measured point in the liquid storing barrel 2 can be sent variation, and liquid level is through cursory 5 and the 3 generation displacements of connecting link 4 drive differential transformer type displacement meters, and the displacement sum of the displacement of measured point and reference point 9 is exactly the displacement deformation amount of measured point.The mode of acquisition system through patrolling and examining, collecting and detecting device 1 detected displacement successively, and compare the sedimentation value that draws the measured point after the calculating with the displacement of reference point 9, sedimentation value is passed to server through communication module and supplies the testing staff to use.
