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.

1 , the system according to the present invention includes a drone 100 , a GPS satellite 200 providing information on the shooting location of the drone 100 , and an underground facility image obtained by the drone 100 . and an image processing server 300 for receiving and image processing.

At this time, the drone 100 is an unmanned photographing device that moves to a photographing area while being mounted on a vehicle and takes a photograph while flying over a set photographing area.

In particular, the drone 100 is capable of low-flying and provides a very efficient detection function because it can acquire shape information of underground facilities using DAS (Distributed Acoustic Sensing) technology.

In addition, the GPS satellite 200 provides the location information at the time when the drone 100 arrives at the shooting area to take the picture, which is a map because the location information is mapped together with the image information during image processing to become a numerical map. It has the advantage of being able to check the shape of the underground facility along with the location from the top.

In addition, the image processing server 300 includes a housing 310, a plurality of processing modules 320 mounted inside the housing 310, and an openable and openable door 330 as shown in FIGS. 2 and 3 . include

At this time, the processing module 320 is a memory module for storing the received image, a pixel processing module for calling the stored image and processing the pixel to form a clear image, and the location information received from the drone 100 on the pixel-processed image. It includes a mapping module that maps and displays, and they always generate a lot of heat because they have to process a large amount of image data.

Therefore, if these processing modules 320 are not cooled quickly inside the housing 310, they are easily deteriorated due to deterioration phenomena such as errors, shutdown due to overload, short circuit due to dust generated inside the housing 310, etc. The lifespan is shortened, and the processing efficiency is rapidly reduced.

In particular, as in the example of FIG. 3 , the main board 312 is mounted inside the housing 310 , and since a plurality of processing modules 320 are mounted in the main mode 312 , an efficient cooling means is implemented. need.

For this purpose, the most common method is to use a fan to cool it, but when using a fan, a lot of dust gets stuck in the fan in a short time, which reduces the cooling efficiency, and if dust gets stuck in the PCB type processing module, a short circuit is made. may occur.

Accordingly, in the present invention, as shown in FIG. 3 , the cooling chamber CH is fixed and the cooling air flowing inside the cooling chamber CH is continuously circulated by the cooler 1500 and the air circulation fan 1510 , while the main board 312 . ) is configured to indirectly cool.

At this time, the inter rod SA is a member having an insulating function, sealing property and heat dissipation property, and is closely provided in a rectangular frame shape along the edge.

Therefore, since the liver rod (SA) must perform an important function, it is not simply composed of a general silicone resin, but must be prepared in a specially combined composition. To this end, in the present invention, 10% by weight of XanthanGum, It is composed of 10% by weight of the pin, 10% by weight of copper powder, 5% by weight of epoxy resin, 10% by weight of polysiloxane, 10% by weight of aluminum oxide powder, 20% by weight of ethyl acetate and the remaining acrylic resin.

At this time, xanthan gum is very useful as a component of the acrylic heat-dissipating adhesive of the present invention because it has excellent transparency and light transmittance, and has a low viscosity and does not need to be dissolved in a separate solvent. In addition, triphenylphosphine is added to promote curing and stabilize curing of the pressure-sensitive adhesive.

In addition, copper powder has excellent malleability and ductility, and has excellent electrical conductivity as well as thermal conductivity. Polysiloxane is added to prevent cracks or drop-offs by suppressing the increase in hardness after curing of the pressure-sensitive adhesive to maintain elongation. Epoxy resin strengthens the cushioning properties and improves interfacial fixation.

In addition, aluminum oxide powder is added to improve heat dissipation properties by implementing thermally conductive filler properties while maintaining the formability after adhesion of the pressure-sensitive adhesive. In addition, ethyl acetate is usually used as a diluent or solvent for paints, but in the present invention, as a dispersion stabilizer, uniform dispersion induction and anti-agglomeration are used to prevent deterioration of heat dissipation properties due to agglomeration or micro-dispersion of a large number of powders in the process of dispersion. added for

And, the acrylic resin has a low specific gravity and high adhesive properties while maintaining colorless transparency, so it is the most suitable base resin as an adhesive according to the present invention.

On the other hand, the cooler 1500 is a small thermoelectric element (TEM), and is configured to generate cooled cooling air by allowing the cooling air to contact only the heat absorbing side.

In addition, the cooling air is configured to be smoothly circulated by the air circulation fan (1510).

In other words, according to the present invention, a plurality of processing modules 320 are mounted on the back side of the maybond (B) under the interposition of the interstitial rod (SA), which is closely attached along the rear edge of the main board (312), and the intervening rod (SA).

Accordingly, it is possible to stably cool the main board 312 , thereby stabilizing the system as well as maintaining the efficiency of the system.

In particular, in the present invention, as in the example of FIG. 2 , since the treatment modules 320 have the shape of the housing 310 , the main causes of deterioration are moisture and dust (dust), so that the housing 310 can be periodically removed. A vacuum processor 1600 is further installed on the side.

The vacuum processor 1600 can also improve the cooling efficiency through the cooler 1500 by maintaining the inside of the housing 310 at the same level as atmospheric pressure or slightly lower than atmospheric pressure.

The vacuum processor 1600 includes a cylindrical vacuum chamber 1610 . The vacuum chamber 1610 includes a plurality of connection pipe portions 1620 so as to be in communication with the inside while being sealed through one side of the housing 310 .

In addition, a discharge pipe 1630 is provided at one end of the vacuum chamber 1610, a solenoid valve 1640 is installed on the discharge pipe 1630, and a valve controller 1650 is installed in the solenoid valve 1640.

At this time, although not shown, the valve controller 1650 may be connected to and controlled with the above-described controller (not shown). Alternatively, it may be controlled by connecting a separate computer. In this case, the vacuum processor 1600 is not always operated, but is periodically attached and detached and used.

In particular, a moisture absorber 1660 is installed at the end of the exhaust pipe 1630 , and an exhaust port 1662 is installed in the center of the outer surface of the moisture absorber 1660 after moisture absorption and dust are collected through the moisture absorber 1660 . Only purified air is discharged into the atmosphere.

In this case, the moisture absorber 1660 is configured to be replaceable in a cylindrical shape.

In addition, a vent hole 1652 is formed in the valve controller 1650 to vent in the event of a sudden overload or to induce air intake through the vent hole 1652 to induce rapid facility stabilization.

In addition, a tube body 1612 communicating with the inside is fixed to a part of the outer peripheral surface of the vacuum chamber 1610, a vacuum detection sensor 1670 is installed in the tube body 1612, and the vacuum detection sensor 1670 is a controller and connected

Here, the vacuum detection sensor 1670 preferably uses a digital vacuum sensor, and a digitized numerical value of the vacuum degree inside the vacuum chamber 1610 can be measured.

Accordingly, the controller can continuously check and manage the degree of vacuum inside the housing 310 .

By configuring in this way, it is possible to optimize the drive environment of the mounted processing modules 320 by keeping the inside of the housing 310 in a clean state as well as securing the cooling efficiency.

On the other hand, the drone 100 is implemented in a state in which GPS communication is possible with the GPS satellite 200 and is also capable of wireless communication with the image processing server 300 . That is, a GPS communication module and a wireless communication module are built-in.

In addition, a fixing table 110 is provided on the lower surface of the drone 100 , and an underground facility detection unit DT and a ground photographing unit CM are provided on the fixing table 110 , respectively.

At this time, the underground facility detection unit DT is detachably fixed to the detection unit fixing guide 112 provided at the lower end of the fixing unit 110 .

To this end, the underground facility detection unit DT includes a detection unit slider 122 fitted to the detection unit fixing guide 112 and a lower portion of the detection unit slider 122, as shown in the example of FIG. A fixed detection block unit 124, a distributed vibration sensor 126 provided inside the detection block unit 124 and electrically connected to a control unit (not shown) of the drone 100, and the distributed vibration sensor ( 126) and a pulse scanner 128 for generating high-frequency pulses, and an optical fiber LF connected to the pulse scanner 128.

At this time, the driving and control of the distributed vibration sensor 126 and the pulse syringe 128 are performed through the control unit of the drone 100 , and the power required for driving also uses the battery of the drone 100 . For this purpose, although not shown, the drone 100 is connected and wired through a separate lead wire.

Thus, according to the control signal of the control unit, the drone 100 is operated to fly in low altitude so that the optical fiber LF can move slowly while touching the ground.

And, detection of underground facilities is made by distributed sensing technology using optical fiber (LF). The distributed vibration sensor 126 detects and analyzes the optical signal that is scattered and returned after scanning a laser pulse of a specific wavelength, predicts the presence and shape of underground facilities through deformation or change of vibration, and transmits it to the control unit. is done

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

On the other hand, as illustrated in FIGS. 4 and 6 , the ground photographing unit CM is detachably fixed to the imaging unit fixture 114 provided at the lower end of the holder 110 .

In particular, the ground imaging unit (CM) according to the present invention is configured to improve the optical structure of the camera to increase the shooting efficiency, and at the same time recognize the shape of the underground facility and photograph the surrounding ground objects to match each other, and position information It is used to obtain basic information that can be mapped to a numerical map. That is, it has a redundant acquisition structure of information.

To this end, as shown in FIG. 6 , the ground photographing unit CM has a main housing 1200 having an optical system implemented therein, and is exposed to the upper portion of the main housing 1200 and is detachable from the imaging unit fixture 114 . It includes an imaging unit 1210 that is possibly fixed, and a telephoto lens 1220 exposed under the body housing 1200 .

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

Here, it is usually photographed at a low magnification, but high magnification is included for this purpose because it must be photographed at a high magnification when photographing above-ground objects rather than acquiring the shape of an underground facility.

Accordingly, a first beam split 1230 is installed directly above the telephoto lens 1220 of the present invention, and a first reflection mirror 1240 is installed in parallel with the first beam split 1230 at an interval, and the A first magnification lens 1250 is installed directly above the first beam split 1230, and a second magnification lens 1260 is installed directly above the first reflection mirror 1240, and the first and second magnification lenses 1260 are installed directly above the first beam split 1230. A second beam split 1280 is completely divided between the magnification lenses 1250 and 1260 by a partition wall 1270 , and is disposed directly above the first magnification lens 1250 to coincide with the immediately below of the imaging unit 1210 . ) is installed, a second reflection mirror 1290 is installed directly above the second magnification lens 1260 , 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 with a gear GR driven by a motor. made to be movable.

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 beam flow to the second magnification lens 1260 and the beam 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 control unit (not shown) of the drone 100 .

Then, the subject is imaged in the order of the telephoto lens 1220 → the first beam split 1230 → the first magnification lens 1250 → the second beam split 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 beam flow to the second magnification lens 1260 and blocks only the beam flow to the first magnification lens 1250. This is controllable by controlling the driving of the motor by a controller (not shown) to move the gear GR.

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

Accordingly, since a combination of magnifications is possible with one camera, it is easy to control various magnifications, and a clearer image can be obtained.
