METHOD OF THE SUPERVISORY CONTROL OF GEODESIC MEASUREMENTS AND THE SIGHT ROD FOR ITS IMPLEMENTATION Russian patent published in 2004 - IPC

FIELD: measuring technique.

SUBSTANCE: the invention is dealt with the measuring technique and may find application at conducting single measurements in the geodetic works for the supervisory control of stability of engineering structures, for example, by trigonometric leveling. The method of the supervisory control of geodetic measurements includes taking of measurements, matching of results and determination of weight. At that they additionally compare the length of the collimating ray_{Rc up to the watched target with the length of collimating ray Ro at observation of the target in optimum conditions at maximum resolving power of an aided eye of the supervisor. Then they determineRo, aligning the target with the smallest of the visible graphical installations on a scale of the sight rod fixing variation of geometrical sizes of the separately sighted installations according to variation of Ro. Weight of the measurement р is determined by value of Rc / Ro. The sight rod used for the supervisory control of geodesic measurements contains on a light background of a test plate a graduated scale made in the form of a column of N rows of dark graphical installations with varying sizes in each subsequent row. The graphical installations are made in the form of circles, a diameter di of which in each i-th row corresponds to a resolution of an aided eye of the supervisor for a fixed length Ri of the collimating ray and is determined from the following dependence di = (ϕ″m x Ri ) / ( ρ x Го*), where i = 1...N, ϕ″m - average resolution of an eye of the supervisor in optimum conditions, ρ - number of seconds in a radian equal to 206265 ", Го* - magnification of the device spyglass lenses. The circles are placed with a spacing between their centers equal to 2 di. The technical result is improvement of accuracy and reliability of measurements, simplification of the design and expansion of functionalities of monitoring aids of measurements.}

EFFECT: the invention allows to improve accuracy and reliability of measurements, to simplify the design and to expand functionalities of monitoring aids of measurements.
