Abstract

The invention discloses an all-day and full-automatic photoelectric plumb line coordinatograph which comprises a light source module, a plumb line, a field angle control window, a core circuit and a peripheral circuit. The core circuit is respectively connected with the peripheral circuit and the light source module and is used for controlling the light source brightness of the light source module; the peripheral circuit is used for providing voltage; the plumb line is fixed on a measured building; the light source module and the field angle control window are arranged on the two opposite sides of a plumb line respectively, and the light source module generates parallel light in the direction of the plumb line and the field angle control window. The plumb line generates a shadow under the irradiation of the parallel light, and the shadow is projected on the core circuit through the field angle control window and is detected and calculated by the core circuit. According to the coordinatograph, the field angle control window is adopted, environment background light in parallel light can be effectively inhibited, and the detection precision and the all-day environment adaptability are improved.

Description

technical field [0001] The invention relates to the field of civil engineering structure monitoring, in particular to an all-time, fully automatic photoelectric vertical line coordinate instrument, which is suitable for large civil engineering structures, such as dams, nuclear power plant reactor containment, buildings, bridges, tunnels and other large constructions. Different elevation horizontal displacement and tilt deformation monitoring of structures. Background technique [0002] Due to the influence of engineering geology, external conditions and other factors, large-scale civil engineering structures will have certain deformations during construction and operation. It usually manifests as inclination, subsidence, distortion, cracks, etc. in the whole or part of the engineering structure. If it exceeds a certain limit, it will affect the normal use of buildings and structures, and even threaten the safety of human life and property. Therefore, certain technical means...
