Description

Geodetic survey stabilizer with improved precision

The present invention relates to a geodetic survey stabilization device with improved precision in the field of geodetic surveying technology, and more particularly, not only geodetic survey using a total station, but also induces stabilization of surveying equipment through a buffer function, and furthermore, including wireless communication It relates to a geodetic survey stabilization device with improved precision so that it can implement a detection function for underground facilities, as well as increase the optical distance, increase the precision according to the geodetic survey, and shorten the working time.

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, in order to produce a digital map as well as to produce a GPS-based geographic information product including various topographical information, geodetic and surveying work that confirms whether the captured area is accurately photographed as well as a topographical photograph 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 used to create aerial photographing information by turning the aerial photograph obtained through aerial photographing into data, and then using it to produce a numerical map.

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

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

Therefore, it is necessary to measure the error-generating point and correct the error. In order to accurately position the measured 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 company performing a project 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, in accordance with the function complexing strategy of recent surveying instruments, there are problems to be solved such as stabilization of the total station as well as reduction of the geodetic survey time due to the improvement of precision and measurement distance.

Hereinafter, a preferred embodiment according to the present invention will be described in more detail with reference to the accompanying drawings.

Prior to the description of the present invention, the following specific structural or functional descriptions are only exemplified for the purpose of describing embodiments according to the concept of the present invention, and embodiments according to the concept of the present invention may be implemented in various forms, It should not be construed as limited to the embodiments described herein.

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.

The resin sheet 106 is a polyurethane resin sheet to provide elastic cushioning power, waterproof power, and stain resistance. To this end, the resin sheet 106, based on 100 parts by weight of the polyurethane resin, silicon carbide nanopowder 5 parts by weight, ethyl acetate 15 parts by weight, lithium silicate 3 parts by weight, parinaric acid 2.5 parts by weight, diazonium salt 5 After mixing 5 parts by weight of calcium methyl silane trioleate, it is molded into a sheet shape.

At this time, the silicon carbide nanopowder is added to induce the stabilization of the equipment by strengthening the heat dissipation buffer according to the elastic deformation of the three-dimensional pores; Ethyl acetate is added as a dispersion stabilizer for nanopowders to prevent agglomeration or micro-dispersion and to suppress contamination during the dispersion process.

And, lithium silicate contributes to the formation of a waterproof coating film and enhances stain resistance; Farinaric acid is added to promote softening of the resin to increase bonding properties and to increase water tightness and antifouling properties.

In addition, diazonium salts promote curing; Calcium methylsilanetrioleate is added to enhance waterproofing properties.

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 .

In particular, a distributed vibration sensor 136 may be further installed inside the fixed plate 130, and a pulse scanner PJ that generates a high-frequency pulse, and an optical fiber LF connected to the pulse scanner PJ. may include more.

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.

In addition, the connection terminal is connected to the controller 200 mounted inside the main body 100 so that the controller 200 can control the distributed vibration sensor 136 and the pulse syringe (PJ), and also the controller ( 200) also performs a basic control function of the measurement equipment unit (110).

At this time, underground facility measurement is made 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.

On the other hand, in the present invention, as in the example of FIG. 3 , the camera (CMA) constituting the measurement equipment unit 110 improves the optical structure to make it easy to adjust the magnification, but since it is possible to control the magnification at a high magnification, it is possible to accurately measure up to a long distance. The measurement time can be shortened and the measurement accuracy can be further improved.

To this end, as shown in FIG. 3, the camera (CMA) has a body housing 1200 having an optical system implemented therein, and an imaging unit that is exposed to one side of the body housing 1200 and can be docked by a surveyor ( 1210 ) and a telephoto lens 1220 exposed to the other side of the body housing 1200 .

At this time, the imaging unit 1210 is a means for storing a digital image at the same time as the eyepiece function, and the telephoto lens 1220 is a lens that can be adjusted to various magnifications so as to take close-up shots of the target.

Here, the image is usually captured at a low magnification, but when the measurement is to be performed with increased precision even when the target is placed at a greater distance, the image can be captured at a high magnification.

Accordingly, a first light splitter 1230 is installed on the left side of the telephoto lens 1220 of the present invention, and a first reflection mirror 1240 is installed in parallel with the first light splitter 1230 at an interval, and the A first magnification lens 1250 is installed on the left side of the first light splitter 1230, a second magnification lens 1260 is installed on the left side of the first reflection mirror 1240, and the first and second magnification lenses A space between 1250 and 1260 is completely divided by a partition wall 1270 , and a second light splitter 1280 is disposed between the first magnification lens 1250 and the imaging unit 1210 , and the second magnification lens On the left side of 1260, a second reflection mirror 1290 is installed in parallel to the second light splitter 1280, and a sliding guide SLG is installed on the upper end of the partition wall 1270, and the sliding guide SLG. is provided with a slider SL that selectively opens the first and second magnification lenses 1250 and 1260 while sliding along it, and the slider SL is toothed and moved with a gear GR driven by a motor. configured to be able to

Thus, it is possible to increase the magnification that can be raised by the telephoto lens 1220 alone. At least two magnifications, that is, a ×2 magnification and a ×4 magnification can be further utilized, so that even detailed features can be captured.

For example, if the telephoto lens 1220 has a high magnification, for example, the first magnification lens 1250 , the slider SL blocks the light flow to the second magnification lens 1260 and the light to the first magnification lens 1250 . Only the flow is in an open state, which is controllable by moving the gear GR by controlling the driving of the motor by the controller (not shown) of the measuring device 110 .

Then, the target, which is the subject, is imaged in the order of the telephoto lens 1220 → the first light splitter 1230 → the first magnification lens 1250 → the second light splitter 1280 → the imaging unit 1210 .

On the other hand, in the case of passing through the second magnification lens 1260, which is an ultra-high magnification, the slider SL opens the light flow to the second magnification lens 1260 and blocks only the light flow to the first magnification lens 1250, This is controllable by controlling the driving of the motor to move the gear GR.

Then, the target, the subject, is telephoto lens (1220) → first light splitter (1230) → first reflection mirror (1240) → second magnification lens (1260) → second reflection mirror (1290) → second light splitter (1280) ) → images are captured in the order of the imaging unit 1210 .

Accordingly, since it is possible to combine magnifications with one camera (CMA), it is easy to control various magnifications, and clearer target imaging is possible, enabling precise geodetic surveying to a greater distance and shortening the surveying time. .
