Tolerance settlement monitoring device, system and method

Abstract

The invention discloses a tolerance settlement monitoring device. The device is connected to an external gas-guide pipe and a liquid-guide pipe. The tolerance settlement monitoring device comprises atank body, a separation plate, a breather pipe, and a pressure sensor. The invention discloses a tolerance settlement monitoring system. The system comprises the at least two tolerance settlement monitoring devices, a liquid storage tank, the gas-guide pipe, the liquid-guide pipe and an upper computer. The invention also discloses a tolerance settlement monitoring method. The method comprises thefollowing steps of monitoring a pressure signal and selecting a reference point; acquiring a first pressure signal change value and acquiring a second pressure signal change value; and acquiring a sedimentation value. An adaptation capability to an environment is increased, detection precision is improved, a pipeline blockage problem is overcome, construction efficiency is increased, a failure rate and maintenance cost are reduced, and the volatilization of a liquid medium is avoided.

Description

technical field [0001] The invention relates to the technical field of measuring instruments, in particular to a tolerance type settlement monitoring device, system and method. Background technique [0002] Such as figure 1 , figure 2 As shown, the current existing Unicom pipe settlement monitoring system is composed of a pressure static level (such as figure 1 H1-Hn) or liquid level static level (such as figure 2 L1-Ln), the reference level reservoir (such as figure 1 / figure 2 Y4), liquid conduction medium (such as figure 1 / figure 2 Y1) Unicom pipe layout plus computer acquisition and monitoring platform (such as figure 1 / figure 2 Y6) composition. [0003] Such as figure 1 As shown, the working mode of the pressure-type static level: when the position of the H1 test point changes (the settlement monitoring in the vertical direction can only monitor the position change in the vertical direction), between the H1 test point and the reference tank Y4 level ...

AI Technical Summary

Problems solved by technology

The difference in local air pressure has a great influence on the test accuracy of settlement (the settlement value often needs to be accurate to 10Pa level, that is, millimeter level), which seriously affects the test accuracy

Moreover, the scheme directly connected to the atmosphere will cause a larger air pressure difference at the air communication port of the static level when the local air flow is relatively large (wind blowing, etc.), and the error value of the static level will be increased.
