Problems solved by technology

However, the existing measures have the problems of low measurement efficiency and low measurement accuracy: measuring and adjusting the i angle before leveling every day often consumes a lot of energy and time of the surveyors, and the measurement efficiency is low; The change of i-angle cannot be found in time, resulting in a decrease in the accuracy of the measurement results; if the measurement accuracy is found to be low and the measurement accuracy must be ensured, the measured results can only be discarded, and after re-measurement and adjustment of the i-angle, re-measure the level from the starting point to the end point. Reduces measurement efficiency
However, in the process of actual manufacture and use, it is found that this patented technology still has the following shortcomings: (1) The implementation technology is complex and the manufacturing cost is high; (2) The direct real-time dynamic detection is not the i-angle change of the collimation axis optical path itself, but the It is to detect the displacement signal of the free pendulum of the automatic compensator. It is necessary to further convert the displacement signal of the pendulum into the i-angle change of the optical path, which involves the calibration and conversion of the pendulum displacement, which affects the detection accuracy and efficiency of the i-angle change.

Abstract

The invention discloses a novel level gauge with an i angle detection function, which can improve the leveling accuracy, reliability and efficiency. The level gauge comprises a shell, wherein an object lens, a focusing lens, an automatic horizontal sight line compensator, a light splitter, a cross hair reticle and an eye lens which have the same center line are sequentially arranged inside the shell from inside to outside; an electronic reader, a display and control terminal and a first power supply are further arranged on the shell; a level is arranged on the outer side surface of the shell;a built-in light source, a scattering glass, a vertical transparent microcoded ruler and a convex lens which have the same center line are sequentially arranged on the other side of the object lens from far side to near side; the built-in light source, the scattering glass, a vertical transparent microcoded ruler and the convex lens and object lens and the eye lens form the same light path; an alarm device is connected with the display and control terminal.

Description

technical field [0001] The invention relates to a leveling device in the field of geodetic surveying and engineering surveying, in particular to a novel leveling instrument with i-angle detection function which can improve leveling accuracy, reliability and efficiency. Background technique [0002] A traditional level measuring device is composed of a level and two leveling rods. The level is composed of an objective lens, a focusing lens, an automatic horizontal sight compensator, a beam splitter, a crosshair reticle, an eyepiece, an electronic readout device and a display and control terminal. When measuring, first place the two leveling rods vertically at the two points A and B on the ground, and then set the level at the middle position of the two points A and B, and use the leveling telescope to collimate the axis (that is, the intersection point of the crosshair and the The line of sight provided by the optical center of the objective lens) respectively aim at and rea...
