Description

A geodetic survey system that can minimize the error value of measured data

The present invention relates to a geodetic survey system, and more particularly, to a geodetic survey system capable of minimizing an error value of measured data.

In general, for public surveys and underground facility surveys ordered by public institutions such as the state, geodetic surveys should be performed first. Geodetic surveying refers to all activities of measuring the horizontal distance, elevation difference, and direction, determining the position of each measurement point, displaying it in drawings or numerical values, and staking out on-site.

Among these geodetic surveys, level survey is a survey to find the difference in height between two points using a survey device such as a target, leveler, and total station, and its accuracy is 5mm * S/2 (here, S is the one-way distance, and the unit is km), so detailed measurement is required.

1 is a view for explaining a method of measuring a level using a conventional standard and measuring instruments, Figure 2 is a perspective view showing the state of the conventional standard.

In the first step, the target number 1 is set at the ground reference point (a0) of known altitude, and the machine number (機械手) is a level machine, etc. Read the scale of the target scale (1) with the measuring instrument (2).

In the second step, the target number moves to the first point (a1) and sets up the target scale (1), and the machine number changes the direction of the surveying device (2) at the observation point (b1) and passes the first through the surveying device (2) Read the mark scale of the point. Here, the altitude of the first point is obtained from the difference between the scale read at the ground reference point (a0) and the first point (a1) and the altitude of the ground reference point.

In the third step, the machine number moves to the second viewpoint (b2) behind the first point (a1), and the reference number 1 changes the direction from the original position (the first point), so that the measurement number 1 is surveyed. When looking at the device 2, the machine operator reads the scale scale of the first point a1 with the measuring device from the second observation point b2.

In the fourth step, the target scale moves to the second point (a2) and sets the target scale (1), and the machine number reads the scale scale of the second point (a2) at the second observation point (b2). Here, the altitude of the second point is obtained from the difference in scale between the first point (a1) and the second point (a2) read from the second observation point (b2).

In this way, while continuously moving the target scale (1) and the measuring device (2), the direction of the target at each point and the measuring device at each observation point is changed, and the scale is read to obtain the altitude of each point to the target point.
