Embodiment Construction

[0047] The remote displacement measurement system of the present invention includes a target fixed on the measured object and a remote displacement sensor arranged at a long distance, and the remote displacement sensor is arranged on a fixed fulcrum with negligible deformation.

[0048] Such as figure 1As shown, the remote displacement sensor of the present invention includes an optical lens 1 , an image sensor 2 , a core control function unit 5 , a processing storage unit 6 , a trigger control unit 3 and a remote communication unit 4 .

[0049] The optical lens 1 is aimed at the target set on the target to be measured. In the application, a zoom lens can be selected to image targets of different distances and sizes onto the image sensor. This working method has good adaptability to the measurement target and is It has the characteristics of large measurement range, wherein the image sensor 2 is a CCD or CMOS sensor, which is used to acquire images of the measured target in re...

Abstract

The invention discloses a remote displacement measurement system and a remote displacement measurement method. A remote displacement sensor comprises an optical lens (1), an image sensor (2), a core control functional unit (5), a processing and storing unit (6), a trigger control unit (3) and a remote communication unit (4), wherein the core control functional unit (5) comprises a trigger signal detection module, a target template loading and normalizing module, an image data acquisition module, an image graying and zooming module and a target image matching and detecting module (7). Due to the fact that the image sensor is used for acquiring the image of a target on an object to be measured and the displacement parameters of a bridge are obtained by processing the image, the remote displacement measurement system and method have the advantages that the precision is high, the structure is simple and reliable, two-dimensional and real-time measurement are achieved, and the measurement span is large. The remote displacement measurement system and method are suitable for long-term, online and multi-point measurement.

Description

technical field [0001] The invention belongs to the technical field of mechanical measurement, and relates to a displacement and deformation measuring device applicable to targets such as bridges, dams and structural parts, in particular to a displacement sensor for remote measurement. Background technique [0002] The deformation of bridges, dams, structural parts and other objects mainly includes static deformation and dynamic deformation. Static deformation refers to the deformation that changes slowly such as foundation subsidence, inclination and stress relaxation. Dynamic deformation refers to the deformation caused by wind, temperature, earthquake and traffic load. The short-term deformation caused by , its parameter monitoring plays an important role in the security assessment analysis of the target. Many countries in the world have invested a lot of manpower and material resources in the research of bridge deformation measurement technology. [0003] Traditional br...
