Abstract
The present invention relates to a leveling system for leveling precision by checking error factors.
According to the present invention, if a difference from the first set collimation distance occurs after confirming the collimation distance before the back collimation, the position of the level unit can be adjusted to accurately correct the collimation distance at which the error occurs. That is, the present invention confirms the factors causing the error of the level measurement data, and the correct collimation distance is kept constant so that accurate level measurement data can be obtained by reducing the error of the collimation value.
Description
The present invention relates to a leveling system for leveling precision by checking error factors.
Surveying generally refers to all activities that measure horizontal distance, elevation difference and direction, determine the position of points mutually and display them in figures or numerical values.
Among these, a level measurement refers to observing the elevation difference of a specific point, and is also referred to as an elevation measurement or a level measurement.
During the level survey as described above, there is a direct gauging survey in which the height difference between two points is obtained by using a skeleton (stiff) and a leveler.
The direct orbit measurement is generally performed by setting one path from the reference point to the target point, setting N midpoints on the path, moving the staff and leveler, and measuring each point.
At this time, in performing the measurement, it is necessary to accurately level the leveler, and when the working environment is dark, it is necessary to brighten the working environment.
On the other hand, the direct level measurement is carried out equally with the leveling device as shown in FIG. 1.
In other words, it is very important to keep the distance between the midpoints constant in the above-mentioned direct balance measurement. This is because accurate measurement data can not be obtained due to earth curvature error and light refraction error when the collimation distance is different.
According to an aspect of the present invention, there is provided a leveling apparatus for leveling a leveling machine, the method comprising: And to provide a leveling leveling system for improving the precision by checking an error factor which can obtain accurate leveling data.
According to an aspect of the present invention,
The mounting mechanism (100) according to any one of
A receiving unit T3 for receiving a distance signal from the
And a control unit.
According to the present invention as described above, the horizontal level of the leveling device can be accurately adjusted through the leveling device, and the working environment can be brightened through the lighting device.
Further, according to the present invention, if a difference between the collimation distance and the collimation distance is checked after the collimation distance is checked before the collimation, the position of the collimator can be adjusted to correct the collimation distance. That is, the present invention confirms the factors causing the error of the level measurement data, and the correct collimation distance is kept constant so that accurate level measurement data can be obtained by reducing the error of the collimation value.

The level measuring terminal T comprises an input unit T1 for inputting data, a display unit T2 for displaying data, a receiving unit T3 for receiving a distance signal from the
The control unit T4 indicates the distance value according to the distance signal from the receiving unit T3 to the display unit T2 and receives the measured value from the input unit T1 to calculate the elevation value.
A method of measuring according to the present invention will be described with reference to FIGS. 9 to 13. FIG.
First, a general direct and indirect surveying method will be briefly described as follows.
The surveyor sets up one path to the target point, sets N midpoints on the path, and then moves the ruler and leveler to each point.
For example, as shown in FIG. 9, when the midpoint is set to three, and the height difference between the points A and B is obtained, the leveling unit and the surface block are alternately arranged from point A,
That is, the surveyor positions the leveler ahead of the skater and then collimates it for the purpose of backwardness.
Then, the surveying engineer inputs the backscattering value through the input unit (T1) of the leveling terminal (T).
Subsequently, the surveying operator moves the base block 32 to the front of the leveler 10 and collimates it again for display purposes.
Then, the surveyor inputs the display collimation value through the input unit (T1) of the level measurement terminal (T).
Thereafter, the back and forth display operations are repeated along the path, and the display standard value and the back visual standard value are input to the level measurement terminal T. FIG.
Here, a method of obtaining leveling data (elevation value) according to point B through each of the exhibition collimation values and the backward collimation values will be described with reference to
Where B.S (Back Sight) is the backsight value and F.S (Fore Sight) is the exhibition sight value.
In this embodiment, the level measurement data of point B can be obtained using the values stored in the control unit T4 of the level measurement terminal T. [ On the other hand, in the present embodiment, although the calculation is performed by the control unit T4 when calculating the values, the surveyor may manually calculate the values.
On the other hand, when leveling data is obtained as described above, it is important to level the
Also, it is very important to keep the collimation distance constant when the level measurement data is obtained as described above. However, the location of a certain midpoint on the path that was initially set due to the misunderstanding of the surveyor or the location change of the midpoint marker may change. In this case, the collimation distance through the certain midpoint is changed and an error occurs in the collected level measurement data.
That is, when the collimation operation is performed along the path as shown in FIG. 10, the position of the
In this case, the surveyor thinks that the collimation distance is kept constant, but in reality, the collimation distance is not constant and the error of the level measurement data due to the earth's curvature error and light refraction error occurs. In other words, accurate leveling data can not be obtained.
However, in the present invention, after the level meter L is positioned at the y point between the
On the other hand, when the position of the
Then, the surveying engine acquires the backsight value using the
The surveyor then moves the scales to the rear of the level gauge (L) for display purposes and places them at
Subsequently, the surveyor repeats the back and display work, and obtains the level measurement data (elevation value) of the point B through the backward value and the exhibition value obtained through the backward and display work.
