Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0027] refer to figure 1 and figure 2 , the present invention provides a method for calibrating the prism centering rod, which is used to solve the calibration of the bubble deviation on the centering rod. Limited by the site, it can be operated by itself and the cost is low; compared with the existing conventional calibration method, the calibration method of the present invention does not need to use theodolite, and one person can complete the calibration, which is simple to operate and saves manpower and equipment. The method for correcting the prism centering rod of the present invention will be described below in conjunction with the accompanying drawings.

[0028] The normal state of the prism centering rod is that when the air bubble on the centering rod is in the center position, the centering rod is in a vertical state, but sometime...

Abstract

The invention relates to a method for correcting a prism centering rod, comprising the following steps: providing a vertical ball, hanging the vertical ball at a set position, and making the tip of the vertical ball naturally drop to the ground; Place the centering rod at the point where the tip of the vertical ball meets the ground; lift the vertical ball and make the vertical ball naturally drop to the top of the centering rod; adjust the position of the centering rod so that the centering rod The top center of the centering rod is in contact with the tip of the vertical ball so as to realize that the centering rod is in a vertical state, and then the support rod is used to fix the centering rod; and the air bubbles on the centering rod are adjusted so that the The bubble is centered, thereby completing the correction of the centering rod. The method for correcting the prism centering rod provided by the present invention does not require professional equipment, is simple to operate, and can be completed by one person without limitation of the site. cost.

Description

technical field [0001] The invention relates to the field of measuring instrument calibration, in particular to a method for correcting a prism centering rod. Background technique [0002] At present, the more professional way of calibrating the center pole is to use a calibration table for calibration. Although the calibration table calibration has high precision, its applicability is low, and it needs to be completed by an instrument verification unit. In the measurement operation, it is found that there is a deviation of the centering pole bubble, and the self-calibration is generally adopted. The conventional method of self-calibration is: set up the centering pole, and then set up two theodolites in the direction of 90° to each other to observe the verticality of the centering pole, adjust Center the rod so that it is fixed when it is vertical in both directions, then adjust the air bubble to center. Although this method is not limited by time and place, it requires tw...
