Description

Total station for geodetic surveying for geodetic surveying

The present invention relates to a total station for geodetic surveying for geodetic surveying, and more particularly, to implement not only a geodetic survey using the total station but also a function to detect underground facilities including wireless communication in addition to a buffer function, but a battery according to the implementation of the function It relates to a total station for geodetic surveying for geodetic surveying, which is treated to reduce heat generation and is efficient for long-term use.

In general, geodetic surveying includes surveying of national reference points, surveying of topographical features, public surveying and general surveying as basic surveying, and confirming location information (coordinate information) for a specific point or location by surveying.

In addition to the production of numerical maps as well as the production of GPS-based geographic information including various topographical information, geodetic and surveying work to check whether the photographed area is accurately captured as well as topographical photographing of the target area is absolutely required.

In other words, in order to produce and correct a numerical map used in GIS, aerial photographing of a certain area is performed, and the aerial photograph obtained through such aerial photographing is converted into data to produce aerial photographing information, and then a numerical map is produced using this.

After producing a numerical map through this process, aerial photographing is performed again at regular intervals to produce new aerial photographing information, and through this, the numerical map based on the existing aerial photographing information is corrected.

At this time, if there is an error between the coordinates of the geographical features or artificial structures, etc. of the existing numerical map to be corrected and the coordinates of the recorded features or artificial structures, etc. of the newly produced aerial photographing information, whether there is an error in the existing numerical map or It was difficult to determine whether there was an error in the newly produced aerial photography information.

Therefore, it is necessary to measure the error-generating point and correct the error. In order to accurately position the measuring point, a geodetic surveying equipment called a total station is usually used.

Briefly describing such geodetic survey equipment, the geodetic survey equipment is a form in which an electronic theodolite and an optical wave detector are integrated into one device.

This geodetic surveying equipment is largely divided into four components: a vertical angle detector that measures the vertical angle caused by the vertical movement of the telescope, a horizontal angle detector that measures the horizontal angle caused by the left and right rotation of the body, and a distance from the center of the body to the prism These are the distance measuring unit and the tilting sensor that measures and corrects the horizontality of the body.

And, when geographic information is collected through such geodetic surveying equipment, geodetic surveying is usually performed based on the coordinates of the national reference point.

An example of the use of the national reference point is explained. In order to use the national reference point, a business performing company in a specific area receives and uses the national reference point scorecard, which records the location of the national reference point in the area where the project is performed, from the National Geographic Information Service.

However, the improvement of the total station is also required according to the function complexing strategy of recent surveying instruments.

In particular, since the total station is a well-known mechanism and its functions and characteristics are already well known, the description of the original basic function of the total station will be omitted, and only the improved configuration in relation to the present invention will be described.

As shown in Fig. 1, the total station according to the present invention includes a main body 100 in the shape of a square box, a measurement equipment unit 110 mounted on the upper surface of the main body 100, and detachable from the lower surface of the main body 100. It includes a fixing plate 130 .

At this time, the upper surface of the main body 100 is provided with a measuring equipment mounting unit 102 so that it can be attached and detached by fastening the lower fastening portion 112 of the measuring equipment unit 110 to the measuring equipment mounting unit 102 .

In addition, the wireless communication unit 120 is provided on one side of the upper surface or the side of the main body 100 so as to be able to communicate wirelessly with the management server (not shown).

In addition, the lower surface of the body 100 is configured to be detachably attached to the fixing plate 130 , and a tripod 132 is attached to the fixing plate 130 so that the body 100 can be stably erected.

In this case, there is a case in which the tripod 132 is not attached to the fixing plate 130 , which is used for detecting underground facilities.

More specifically, as in the example of FIG. 2 , when assembling the measuring device 110 to the main body 100 , in order to prevent minute vibrations from affecting the measuring device 110 by the clearance generated in the assembling section, the measuring equipment is A disk-shaped magnet 104 having a hole therein is firmly fixed to the inner bottom surface of the mounting unit 102 in the shape of a donut, and the disk-shaped magnet 104 has one hole in the inner hole of the disk-shaped magnet 104. -1.5mm thicker resin sheet 106 is attached.

This resin sheet 106 is a polyurethane resin sheet for imparting an elastic cushioning force.

In addition, a disk-shaped iron piece (not shown) is fixed to the lower end surface of the lower fastening part 112 , and the lower fastening part 112 is screwed while being inserted into the measuring equipment mounting part 102 .

Then, when the screw is finally fixed, it is absorbed by magnetic force under the interposition of the resin sheet 106, so that it is possible to maintain a perfect fixed state while absorbing micro vibrations.

On the other hand, the sliding guide 108 protrudes from the lower surface of the main body 100 .

In addition, a plate-shaped slider 134 is fitted to the sliding guide 108 , and the plate-shaped slider 134 may be a structure integrally protruding from the upper surface of the fixing plate 130 .

If the fixed plate unit 130 is provided with the distributed vibration sensor 136 , it is preferable that the tripod 132 is not provided on the lower surface of the fixed plate unit 130 .

This is because, in this case, the underground facility detection function will be used rather than the geodetic survey.

In addition, a terminal TR is provided on the upper surface of the plate-shaped slider 134 for driving and controlling the distributed vibration sensor 136 and the pulse syringe PJ, and the sliding guide 108 corresponds to the terminal TR. ), it is natural that a connection terminal (not shown) should be provided on the inner ceiling surface.

At this time, underground facility measurement is performed by distributed sensing technology using optical fiber.

In this distributed sensing technology, a laser pulse of a specific wavelength is scanned through a pulse injector (PJ) in a state where one end of the optical fiber (LF) is driven to a certain depth underground, and then the scattered and returned optical signal is transmitted to the distributed vibration sensor 136. It is a measurement technology that allows to predict the presence or absence of underground facilities and their shape through changes in deformation or vibration by sensing and analyzing them.

Here, the distributed vibration sensor is called DAS (Distributed Acoustic Sensing) and is widely used to measure the deformation of civil structures.

In addition, a plurality of semi-circular recesses (H) may be formed on the lower end surface of the body 100 , which is to span the hanger 140 as shown in FIG. 3 .

This hanger 140 is provided to make it easier to move by hanging on the shoulder in a state in which the main body 100 is mounted when detecting underground facilities.
