Description

{PRECISION IMPROVEMENT LEVELING SYSTEM}

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.

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 Equation 1 and Equation 2 below.

Figure 112014106153050-pat00001

Figure 112014106153050-pat00003

Where B.S (Back Sight) is the backsight value and F.S (Fore Sight) is the exhibition sight value.

Figure 112014106153050-pat00004

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 leveler 600. Accordingly, in the present invention, the surveying operator aligns the leveling device 100 through the leveling device 1000 so that the leveling device 600 is ultimately leveled.

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 intermediate point 2 is erroneously set, and when the midpoint 2 is set to the midpoint 2 ' And is an intermediate point between the intermediate point 1 and the intermediate point 2 ', not the intermediate point x between the intermediate points 2.

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 midpoint 1 and the midpoint 2 ', the laser distance meter 700 is driven as shown in FIG. 11, (600), and adjusts the position of the level device (600) when the backward sight distance is different from the initially set display sight distance (when an error occurs). That is, the surveying engineer moves the level device 600 as shown in FIG. 12, and positions the level device 600 at an intermediate point x between the midpoint 1 and the intermediate point 2 (position according to the initially set collimating distance) . At this time, the surveying operator can move the leveler 600 by a correct distance while confirming the scale of the scale bar 330 of the first scale device 300. When the scale work 330 of the first scale unit 300 can not be read accurately because the surrounding work environment is dark, the surveyor drives the illuminator 930 of the illuminator 900, The scale bar 330 of the first graduation mechanism 300 can be accurately read by adjusting the vertical angle of the first graduation 930.

On the other hand, when the position of the level device 600 is adjusted, an error tolerance range is set and the error of the level device 600 can be adjusted when the error of the sight distance is out of the allowable error range. For example, when the error tolerance range is 1 m, the position of the level device 600 is adjusted when an error of 1 m or more occurs.

Then, the surveying engine acquires the backsight value using the level device 600, and inputs the obtained backsight value to the leveling terminal T. Further, the surveyor stores the distance d value (error value) between the x point and the y point in the level measurement terminal T. [

The surveyor then moves the scales to the rear of the level gauge (L) for display purposes and places them at midpoint 2. At this time, the surveyor may correct the d value at the position of the midpoint 2 ', and position the midpoint 2 at the midpoint 2'.

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.
