Description

A geodetic surveying system that can minimize measured error values {GEODETIC SURVEY SYSTEM FOR MINIMIZING MEASURED ERROR}

The present invention relates to a geodetic surveying system, and more specifically, to a geodetic surveying system that can minimize measured error values.

In general, for public surveys and underground facility surveys ordered by public institutions such as the government, geodetic surveys must be conducted first. Geodetic surveying refers to various activities such as measuring horizontal distance, elevation difference and direction, determining the location of each measurement point, displaying this in drawings or figures, and staking out on site.

Among these geodetic surveys, level surveying is a survey that determines the height difference between two points using measuring devices such as a marker, level, and total station. The accuracy is 5mm * S/2 in the case of level 2 surveying (here, S is the one-way distance (unit is km), so a detailed survey is required.

Figure 1 is a diagram illustrating a method of measuring level using a conventional marker and measuring equipment, and Figure 2 is a perspective view showing the appearance of a conventional marker.

In the first step, the marker (1) sets the marker (1) at the ground reference point (a0) whose altitude is known, and the mechanical operator uses a level, etc. at the first observation point (b1) a certain distance away. Read the scale on the scale (1) with the measuring device (2).

In the second step, the marker moves to the first point (a1) and sets up the marker (1), and the mechanical operator changes the direction of the measuring instrument (2) at the observation point (b1) and measures the first point through the measuring instrument (2). Read the scale of the point. Here, the altitude of the first point is obtained from the difference between the scales 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 operator moves to the second observation point (b2) behind the first point (a1), and the marker (1) changes direction in place (first point) so that the marker (1) performs the survey. When looking at the device (2), the operator reads the scale of the first point (a1) from the second observation point (b2) with the measuring device.

In the fourth step, the marker moves to the second point (a2) and sets up the marker (1), and the machine operator reads the marker scale at the second point (a2) from the second observation point (b2). Here, the altitude of the second point is obtained from the difference in scales 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 target marker at each point and the direction of the measuring device at each observation point are changed to read the scale to obtain the altitude of each point up to the target point.

At this time, in order to perform accurate geodetic survey work, the surveying equipment must be able to maintain a stable horizontal position and not shake even when external shock or vibration is applied.

However, since the conventional marker must be read by changing the direction of the marker in place, various errors occur depending on the ground condition, and it is difficult to set the marker accurately, so there is a problem that the marker has to hold the marker.

In addition, if the surface of a conventional marker is covered with dust and the scale is not clearly visible, the long marker must be cleaned with a long marker. In this case, there is a problem that it is very difficult to wipe while holding the marker.
