A multi-dimensional monitoring device and its measuring method

Abstract

The invention discloses a multi-dimensional monitoring device. The multi-dimensional monitoring device comprises a reference point device and a monitor device, wherein the monitor device comprises a shell, and a separator and a PCB circuit primary board arranged in the shell, wherein an oval cavity is arranged in the shell of upper portion of the separator, and a liquid pressure sensor is arrangedin the oval cavity; the separator comprises an upper plate and a lower plate, wherein an air pressure offset device is arranged on the inner wall of the shell, the air pressure offset device comprises a groove ring, a disc spring is arranged on the top and bottom of the lower plate located at the inner edge of the groove ring, and an annular resistor induction piece is arranged in the connectingpart of the lower plate and the disc spring; the measuring method comprises the following steps of: S100, setting the liquid level height and the bottom elevation of a non-settling reference point device; S200, acquiring the bottom elevation of the initial oval cavity in the monitor and the liquid level height in the oval cavity, then acquiring the bottom elevation data and the liquid level heightof the oval cavity per unit of time; and S300, calculating a differential pressure type static level settlement change value per unit of time.

Description

technical field [0001] The invention relates to the field of vertical settlement, in particular to a measurement method of a multi-dimensional monitoring device. Background technique [0002] Vertical settlement displacement is a very important safety physical quantity in engineering fields such as foundation pits, highways, railways, subways, underground engineering, etc. During the construction or operation of the project, the settlement deformation can directly reflect the potential safety hazards of the engineering structure and geological structure. Therefore, , settlement monitoring plays a very important role in the field of safety. On the other hand, the settlement monitoring of engineering or geological structures is often accompanied by other deformations, such as horizontal displacement, tilt displacement, etc. In the process of safety monitoring, various change data are required to confirm each other and comprehensively judge the development trend and safety leve...

Problems solved by technology

[0004] First, the traditional method of relying on optical surveying and mapping instruments still exists widely. The use of optical surveying and mapping instruments has the advantages of mature technology, high precision, and flexible measurement point layout, but at the same time, it also relies on technicians to operate, low monitoring frequency, and is restricted by the atmospheric environment. many shortcomings;

[0005] The second is to adopt an information-based unattended monitoring system based on electronic sensing, automatic measurement and control, and Internet of Things technology, but there are generally problems such as single measurement of physical quantities, complex construction, and large interference of measurement accuracy by the environment or other construction operations. The environment is complex, and the measurement and calculation accuracy of a single parameter is poor, and it is impossible to accurately obtain effective parameters of regional subsidence
