REMOTE ALIGNMENT FIXING DEVICE WITH LIQUID CRISTALL DISPLAY

Abstract

The article discusses the issue of increasing the level of automation of alignment measurements when observing settlements and deformations of engineering structures, including hydraulic structures of various structures, which are different in their work on hydrostatic load. The study is based on a comparative analysis of modern means for production of engineering and geodetic measurements using visual optical devices and more modern laser, LED, infrared, and other radiation sources in conjunction with photoelectric and optoelectronic recording devices, including diff action, dispersion, interference methods, devices using mechanical scanning nodes. The theory of liquid crystals, its main characteristics, anisotropy properties, physical properties, design, advantages in terms of energy consumption, weight, and overall dimensions are briefly presented. The method of remote control and information capturing is also considered. As a result of the research, a technical solution was proposed for a geodetic device for alignment measurements with a liquid crystal display with remote control, which is used as an attachment for installing a cell phone, which differs from the known ones in low energy consumption, small dimensions and weight, and a high level of ease of use. The device can be used when performing high-precision alignment measurements in construction, determining horizontal deformations of large engineering structures - dams, bridges, retaining walls, aligning guide ways, installing technological equipment in the design position at base points, installing industrial conveyors and performing other engineering and geodetic works.
