Multi-dimensional monitoring device

Abstract

The invention discloses a multi-dimensional monitoring device which includes a plurality of monitoring devices and a reference point device. The monitoring devices comprise housings which is internally provided with liquid storehouses and gas storehouses, and the liquid storehouses and the gas storehouses are separated by partition plates; and the gas storehouses are internally provided with mainPCBs, the middles of the bottoms of the liquid storehouses are provided with liquid pressure sensing devices, elastic layers are installed on the surfaces of the liquid pressure sensors in a sleevingmode, laser ranging devices are arranged between the main PCBs and the partition plates, the partition plates comprise upper layer plates and lower layer plates with the diameter slightly smaller thanthat of the upper layer plates, and compared with the fact that the inner walls of housing bodies of the lower layer plates are provided with air pressure stress offset devices, the upper layer plates are provided with radial direction offset devices. According to the multi-dimensional monitoring device, the accuracy can be self-corrected and verified, problems of a system can be found, a full-automatic unattended wireless settlement monitoring system is achieved, construction and maintenance processes are simplified, and the material and construction costs are reduced.

Description

Technical field [0001] The invention relates to the field of vertical settlement, in particular to 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. Whether it is during construction or project operation, settlement deformation can directly reflect the potential safety hazards of the engineering structure and geological structure, so , Settlement monitoring has a very important position 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, tilting displacement, etc. In the process of safety monitoring, multiple change data are required to mutually confirm and comprehensively judge the development trend and safety level of deformation. [0003] The curr...

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 common problems such as single measurement of physical quantities, complex construction, and large interference of measurement accuracy by the environment or other construction operations.
