Problems solved by technology

[0003] In the prior art, the connected liquid level settlement deflection detection system is currently a relatively widely used settlement deflection monitoring method, but this method requires a water pipe to connect all the measuring points in series, so it is very inconvenient to install on site; and due to the continuous volatilization of liquid , requiring regular fluid replenishment
In addition, because the balance of the liquid is very slow, it cannot respond to the settlement deformation caused by the vehicle, etc., so the measurement accuracy is low

Abstract

The invention discloses a laser sedimentation flexibility monitor which comprises more than one group of transmitting units and receiving units which are mutually matched, wherein each transmitting unit is a laser used for transmitting a laser beam to each receiving unit, each receiving unit comprises a linear array CCD (Charge Coupled Device) image acquisition unit, an analyzing and processing system and a power supply, the linear array CCD image acquisition unit is used for acquiring the laser beam and converting the laser beam into an electric signal to be transmitted to the analyzing and processing system, and the analyzing and processing system is used for processing the electric signal and then judging sedimentation deformation. The laser sedimentation flexibility monitor has the advantages of simple and compact structure, low cost, convenience for installation and debugging, stable and reliable work, and the like.

Description

technical field [0001] The invention mainly relates to the field of detection equipment for structural engineering, in particular to a settlement deflection monitoring equipment. Background technique [0002] For large structures, such as bridges, dams, buildings, etc., its settlement deformation is an important indicator related to whether the structure can operate safely for a long time. In order to ensure the long-term safe operation of this type of structure and avoid accidents, it is often necessary to do long-term automatic monitoring of the settlement deformation of this type of structure. [0003] In the prior art, the connected liquid level settlement deflection detection system is currently a relatively widely used settlement deflection monitoring method, but this method requires a water pipe to connect all the measuring points in series, so it is very inconvenient to install on site; and due to the continuous volatilization of liquid , requiring regular fluid rep...
