Embodiment

[0014] see figure 1 , figure 2 , the specific steps of this embodiment are:

[0015] Place the total station 1 above the base point D during the measurement through the tripod 2 and level it in the center. Point A is the intersection point of the horizontal axis and the vertical axis of the total station 1. Stand the tower ruler 3 with the vertical level bubble on the One meter away from the total station 1 and adjust it to be vertical, keep the tower ruler 3 parallel to the vertical axis of the total station 1, then adjust the total station 1 to the horizontal, and mark the horizontal axis of the total station 1 objective lens crosshair The intersection point B of the projection line of the silk on the tower foot 3 and the tower foot 3, and then place a plane mirror 4 with a diameter of 10 cm at point B on the tower foot 3, and the plane mirror 4 slides slowly downward from point B, while the total station 1 sight As the plane mirror 4 slowly moves downward, when the image...

Abstract

The invention discloses a method for measuring the height of a total station. The method applies a light reflection principle. After the total station is centered and leveled on a measuring basic point, a vertical tower ruler is erected a certain distance away from the measuring basic point, and one reflective body is arranged on the tower ruler. According to the invention, an image formed by the basic point in the reflective body can be observed from the ocular lens of the total station through vertical movement of the reflective body along the tower body, and the distance from the horizontal axis of the total station to the basic point, i.e., the instrument height, can be solved according to the equal relation between an optical incidence angle and a reflection angle and the included angle relation between parallel lines. The method provided by the invention is simple and clear in principle, simple and cheap in materials, simple to operate, high in precision, easy to grasp and facilitates engineering application.

Description

technical field [0001] The invention belongs to the technical field of engineering surveying, in particular to a method for measuring the height of a total station. Background technique [0002] The current method of measuring the height of the total station instrument is mainly to directly measure the distance from the base point to the side of the total station with a steel ruler, and then obtain the height of the instrument through certain triangular conversion. This method has a large measurement error and is greatly influenced by human factors, which cannot meet the high-precision requirements of engineering measurement. Contents of the invention [0003] The purpose of the invention is to overcome the deficiencies of the prior art and provide a method for measuring the height of a total station. [0004] Thinking of the present invention: use the principle of reflection of light, the distance from the horizontal axis of the total station to the base point can be obt...
