Description

[0001] BENCH MARK SURVEYING SYSTEM [0002]

The present invention relates to a leveling system that is easy to level.

In general, surveying is done first for various civil engineering design and architectural design. Surveying refers to all activities that measure horizontal distance, elevation difference and direction to determine the position of points mutually and display them in figures or figures.

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. Levels are measured through these leveling measures.

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.

This leveling is generally accomplished by setting one path from the reference point to the target point, setting N midpoints on the path, moving the staff and level meter, and measuring each point.

On the other hand, the level measurement can accurately obtain the accurate measurement value by accurately observing the scale of the target through the level meter.

In the past, however, the surveying engineer had to hold the scales when setting up the scaffold, which made it difficult to set up the scaffolding precisely. In addition, if the survey engineer can not accurately construct the skull by mistake, it is not possible to collimate the exact scale with the leveler. If the skull itself is tilted, it is difficult to obtain accurate collimation value.

The control unit 240 calculates the altitude value through the distance value according to the distance signal from the receiving unit 230 and the measured value inputted from the input unit 210. [

Figs. 8 to 11 are diagrams for explaining a case where the upright is vertically uprighted in the present invention, and Figs. 8 to 11 are views for explaining a method of using the present invention As follows.

The surveyor sets one path to the target point, sets N midpoints on the path, and then moves the surface 122 and leveler 110 and measures each point.

For example, as shown in FIG. 7, when the midpoint is set to three and the height difference between points A and B is obtained, the leveler 110 and the block 122 are alternately arranged from point A to the target point do.

That is, at this time, the surveying operator positions the leveler 110 in front of the skate 122 and then collimates it for the purposes of backwardness.

Then, the surveying operator inputs the pre-backsight reference value through the input unit 210 of the leveling terminal 200. At this time, the level measuring terminal 200 receives the distance signal from the ultrasonic distance meter 130 and confirms the distance from the bottom surface of the locomotive instrument body 121a to the ground.

Subsequently, the control unit 240 of the leveling terminal 200 adjusts the distance from the bottom surface of the spindle-mounting mechanism main body 121a to the ground, the thickness of the previously set sprocket mounting mechanism main body 121a, And calculates and stores the backsight reference value to be confirmed. In the present embodiment, the advance backsight reference value represents a scale value of the skewer 122 viewed by the surveyor, and the result backsight reference value refers to a sighting value to be finally confirmed.

Subsequently, the surveyor moves the skewer 122 to the front of the leveler 110 and collimates again for display purposes.

Then, the surveying operator inputs the pre-display collimation value through the input unit 210 of the level measurement terminal 200. The level measuring terminal 200 receives the distance signal from the ultrasonic distance measuring instrument 130 and confirms the distance from the bottom surface of the turntable mounting mechanism body 121a to the ground surface, 240 calculates a result display collimation value to be confirmed by summing the distance from the bottom surface of the spar adjusting mechanism body 121a to the ground surface, the thickness of the sprinkling instrument main body 121a, and the pre-exhibition collimation value . Meanwhile, in the present embodiment, the preliminary exhibition collimation value represents a scale value of the front piece 122 viewed by the survey engineer, and the result display collimation value refers to a collimation value to be finally confirmed.

Thereafter, the back and forth work is repeated along the above path.

As described above, when the display and back-side work from point A to point B is completed, the surveying engineer obtains the elevation of point B by using each of the result display standard values and the result back sight standard values stored in the control unit 240.

Here, a method of obtaining the elevation of the point B will be described with reference to Equations (1) and (2).

Where B.S (Back Sight) is the result backsight value and F.S (Fore Sight) is the result display normality value.

Figure 112014106147682-pat00004

In this embodiment, the elevation of the point B can be obtained by using the values stored in the control unit 240 of the level measuring terminal 200. Although this embodiment is performed by the control unit 240 when calculating the values, it may be calculated manually by the survey engineer.

As described above, it is possible to measure the level point in the level survey through the process of obtaining the elevation.

On the other hand, when performing the level measurement as described above, it is very important to accurately set the scrolls 122. This is because the collimation value is not the required collimation value (collimation value of the upright position) but the collimation value of the collar 122 when the collar 122 is not correctly raised, And the exact elevation can not be obtained.

However, in the case of the present invention, as shown in FIG. 8, when the upright mounting mechanism 121 is inclined and the upright 122 is installed in an inclined state, the pressing ball 123c And the pressing ball 124c of the right horizontal indicating mechanism 124 are not in contact with the piezoelectric element 123b of the left horizontal indicating mechanism 123 and the piezoelectric element 124b of the right horizontal indicating mechanism 124, The light emitting mechanism 123d of the horizontal display mechanism 123 and the light emitting mechanism 124d of the right horizontal mechanism 124 are not turned on.

The surveyor then determines that the top 122 is not correctly erected and adjusts the height of the left support 121b2 of the left fixture mechanism 121b and the right support 121c2 of the right fixture 121c, So that the topsheet 122 is upright. At this time, the left moving panel 121b1 of the left fixing mechanism 121b and the right moving panel 121c1 of the right fixing mechanism 121c adjust the width between the left supporting base 121b2 and the right supporting base 121c2, 121 are installed stably.

4, when the pushing ball 123c of the left horizontal indicating mechanism 123 and the pressurizing ball 124c of the right horizontal indicating mechanism 124 are moved in the vertical direction as shown in FIG. Are in contact with the piezoelectric element 123b of the left horizontal display mechanism 123 and the piezoelectric element 124b of the right horizontal display mechanism 124, respectively. 11, the light emission mechanism 123d of the left horizontal display mechanism 123 and the light emission mechanism 124d of the right horizontal display mechanism 124 are turned on, and the surveyor confirms the lighting 122 are vertically erected, the collimating operation as described above is performed.

In this embodiment, a left-side horizontal display mechanism 123 and a right-side horizontal display mechanism 124 are provided to check the horizontal position of the block mounting mechanism 121. Therefore, even if any one of the left-side horizontal display mechanism 123 and the right-side horizontal display mechanism 124 fails, it is possible to carry out the horizontal check operation of the vertical installation mechanism 121.
