Description

Total GEOGRAPHIC POINT AND LEVEL POINT INFORMATION GATHERING SYSTEM FOR APPLYING RESULTS OF THE GEOGRAPHICAL OBSERVATION DATA}

The present invention relates to the performance of the integrated reference point and the level point through the terrain change measurement, and more specifically, when the terrain changes due to the ground change, such as subsidence can be accurately measured and confirmed and corrected the integrated reference point and level point The present invention relates to an integrated reference point and level point performance collection device through terrain change surveying, which is improved to prevent errors in survey information.

In general, geodesic surveying is a measurement that determines the reference point coordinates of a country's topographic map. It is used for triangulation to determine the coordinates of the triangles, leveling to determine the elevation of the leveling points, Baseline), and tidal wave (tidal wave).

At this time, the triangulation has recently been used by the triangulation survey by the light wave rangefinder and the determination of the shape of the earth or the undulation of the geoid, , And a geomagnetic declination angle (geomagnetism angle) is added to this to add magnetic surveying.

And since the national level reference point becomes the elevation standard for designing, mapping, and installing other reference points for various construction works, it is necessary to carry out high-level surveys when surveying geodetic level elevation using national level reference points. Should be objective and reliable enough.

This leveling (plane survey) is used to determine the height in three-dimensional coordinates and observes elevation or elevation between several points on the surface.

In addition, the standard of national level survey is average sea level (geoid), and the result of level survey is important information that provides data for mapping, design and construction, and design of roads, railways, canals and installation of construction structures of planned height. It serves as a reference point in areas such as surveying drainage characteristics and mapping.

On the other hand, the landfill site is artificially formed by covering sand or soil on the top surface of the hard ground formed naturally, and as time passes, ground subsidence occurs in the soft ground of the top, and the topography changes.

Therefore, after the reference point, which is used as a reference point for surveying, is installed in the landfill, the change of the top and bottom positions of the integrated reference point and level point is continuously monitored to confirm the topographical change, and the integrated reference point and level point should be corrected accordingly.

However, it takes a lot of time and manpower, and very troublesome to check the vertical position change of the integrated reference point and the level point using a triangulation method which is mainly used.

In addition, recently, a method of measuring using a GPS device (GPS) that measures coordinates using a stationary satellite floating on a stationary satellite has been developed and used, but such a GPS device can measure coordinates on longitude and latitude relatively accurately. On the other hand, when measuring the height, there was a problem that the accuracy falls. Therefore, it was not enough to accurately measure the vertical position change of the integrated reference point and the level point using only the GPS device.

Accordingly, Patent Publication No. 0837261 has been disclosed as part of improving the problem.

The disclosed patent is to continuously monitor the top and bottom position changes of the reference point using the GPS and the laser measuring device, it is possible to check the terrain changes in real time and to correct the reference point accordingly.

However, in the case of the registered patent, since the position control of the laser generator is a structure that only rotates and adjusts the angle, the reference position or the level point is changed in three dimensions due to the terrain change such as ground subsidence, so that the reference position is correctly adjusted. There is a limit that can not be.

That is, the topographical change due to the ground subsidence does not simply change the reference point with only the x-coordinate, but causes a three-dimensional change that changes in both the x, y, and z directions. Although it is possible to follow the three-dimensional change in E, it has a limitation that it cannot be followed and tracked if the changed point is out of the position of the reference file.

In addition, the lack of height adjustment makes change tracking more difficult.

The present invention was created in view of the above-mentioned problems in the prior art, and was created to solve this problem, and caused a three-dimensional change as the integrated reference point or level point (hereinafter referred to as 'reference point') is changed due to terrain change due to ground subsidence.

Furthermore, the present invention further includes a function of adjusting the height of the laser generator 24 by modifying the structure of the holder 21b as shown in FIG. 12.

For example, as shown in Figure 12, the cradle 21b is also divided up and down, the upper portion is composed of the elevating member 300, the elevating member 300 to be moved up and down while being fitted to the cradle 21b. It is composed.

To this end, the outer peripheral surface of the upper end of the cradle 21b is cut with a step in the thickness direction to form a slide surface S, and the lower end of the inner surface of the elevating member 300 fitted to the slide surface S is also the same. It is cut to have a step and is configured to fit together.

Then, while constructing a neat appearance, smooth and smooth flow is possible at the time of lifting and lowering.

In addition, the fixing plate 200 is fixed inside the upper end of the holder 21b, the fixing plate 200 is provided so as not to interfere with each other on the upper side of the first drive device (23).

And, the height adjustment cylinder 210 is fixed to the upper surface of the fixed plate 200, the height adjustment cylinder rod 220 is connected to the height adjustment cylinder 210, the end of the height adjustment cylinder rod 220 It is linked to the support plate 310.

In this case, the support plate 310 is a kind of plate that the lifting member 300 is connected across the inner jaw portion, the end of the height adjustment cylinder rod 220 is linked to the center of the lower surface.

Therefore, when the height adjustment cylinder 210 is raised and lowered, the lifting member 300 which is connected to the support plate 310 is raised and lowered smoothly along the slide surface (S).

Therefore, since the laser generator 24 rotatably provided inside the upper end of the elevating member 300 is naturally adjusted to the height, the laser generator 24 is swiveled in the x and y directions along the cylindrical coordinate system, as well as z. Direction height adjustment, in addition to being rotated in the z direction, can also be tilted to accurately follow the change of the reference point despite any ground subsidence.
