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. This method uses the principle of reflection of light. After centering and leveling the total station on the measuring base point, set up a vertical tower ruler at a certain distance from the measuring base point, and place a reflective body on the tower ruler. The image formed by the base point in the reflector can be observed from the eyepiece of the total station by moving the reflector up and down the tower ruler, and the horizontal axis of the total station can be obtained from the equal relationship between the incident angle of light and the reflection angle and the angle relationship between parallel lines The distance to the base point, which is the height of the instrument. The invention has simple and clear principles, simple and cheap materials, simple and convenient operation, high precision, easy grasp and convenient 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...
