As shown, the waterway survey system 1000 according to an embodiment of the present invention may include a drone 100 and a control center 200 that controls the drone 100. For convenience of explanation, reference numerals in FIG. 1 are also referred to.

The control center 200 may select a target area for the drone 100 to fly through various passages, and provide location information, weather information, geographic information, and the like so that the drone 100 can fly to a specific area. To this end, the control center 200 may be connected to various sources capable of collecting ocean current conditions, environmental information, and the like. For example, global environment information, weather information, earthquake information, crust fluctuation information, ocean-specific temperature information (eg, temperature information photographed from a Cheonrian marine satellite), ocean current information, and the like may be collected.

The control center 200 may select a predetermined area of the ocean or a predetermined sea area adjacent to the ocean as a target area for the drone 100 to fly. For example, the control center 200 may set the target area to the cage farm 21, which is mainly used by fishermen, as the target area. Boundary style is a method of raising target organisms with nets in a large space of the sea. Of these, unlike land tank farming, marine cage farming does not require exchange of seawater, and it is possible to cultivate fish in large quantities, which is a trend that is gradually increasing. Here, the target area may change flexibly according to the control of the control center 200.

In addition, the control center 200 may select a nuclear power plant as a target area and measure a temperature change around the nuclear power plant using the drone 100.

The control center 200 may request the drone 100 to measure the temperature of a point 21a of the target area 21. In this case, since the drone 100 can measure the temperature of the point 21a from a distance, the temperature of the sea surface can be measured more efficiently than the conventional method of measuring the temperature of the sea surface using a contact method.

In addition, the control center 200 may transmit to the drone 100 an area, frequency, and time at which the drone 100 measures the temperature of the sea surface based on environmental information, ocean current information, and the like. That is, the flight of the drone 100 may be scheduled by the control center 200.

In addition, the control center 200 drives the thermal image sensing unit 133 to check the temperature distribution of the target area 21 and the outer surrounding area 31 of the target. It can be controlled to detect the temperature distribution.

At this time, if it is determined that temperature measurement is necessary in the target surrounding area 31, the control center 200 provides the drone 100 with location information of a specific point of the target surrounding area 31 to a specific point of the drone 100. It can be controlled to fly and measure the temperature of the area.

The control center 200 may display an image captured through the photographing unit 135 mounted on the drone 100 on the display 240, and the target area 21a may be displayed on the display 240, In addition, the sea area (land) and the sea (sea) may be classified and displayed 313. To this end, the control center 200 may collect chart information. In addition, the control center 200 may be connected to the display 240 through a connection line 33.

The heat distribution 25 of the target area 21a may be displayed on the display 240.

On the other hand, it is described that the control center 200 directly controls the drone 100, but the drone 100 can be automatically driven by inputting necessary information into the drone 100, and the drone 100 is controlled. The drone 100 may be controlled through a drone control platform (not shown).

For example, the second connection part 175 may rotate based on the Y-axis (an axis connecting the centers of the first connection part 171 and the second connection part 175) in spatial coordinates. Accordingly, non-contact temperature measurement, thermal distribution detection of a target surrounding area, area photographing, and the like can be performed flexibly in various directions.

In addition, components of the photographing and measuring unit 130 may be disposed on one rotating plate 137. The rotating plate 137 may rotate 360 degrees in the vertical direction. The rotating plate 137 may be rotated about a second axis, and the first axis and the second axis may be disposed to form a predetermined angle.

For example, the first axis and the second axis may be configured vertically, but the embodiment is not limited thereto. Accordingly, ocean observation in all directions based on the drone 100 may be possible using the first axis and the second axis.

Detailed configurations of the detachable part, attenuating part, a fluid buffer part, and an elevating part will be described in detail below.

The center storage unit 220 may store how the sea surface temperature of the target region will change over time.

The center controller 230 is a control module that overall controls the control center 200. The center controller 230 may control the drone 100 by changing a target area to be measured by the drone 100 based on the collected environmental information, or setting a flight schedule and a period of the drone 100. For example, the center controller 230 may set the periphery of the area designated as the target area back to the target area.

The center display 140 displays (outputs) information processed by the control center 200. For example, the center display 140 may display execution screen information of an application program driven in the control center 200, or UI (User Interface) and GUI (Graphic User Interface) information according to such execution screen information. .

5 is a flowchart illustrating a method of driving a drone according to an embodiment of the present invention.

First, the drone 100 receives location information of the selected target area (S410).

The drone 100 may receive the information from the control center 200, and may receive the information through its own input.

After that, the drone 100 flies over the target area (S420).

At this time, when a control command is not received from the control center 200, the drone 100 performs a predetermined operation (S440). For example, it is possible to fly over a target area or drive the photographing unit 135 to capture an oceanic image and transmit it to the control center 200, but embodiments are not limited thereto.

If a control command is received from the control center (S430), and the control command is a temperature measurement command for a specific point in the target area, the drone 100 measures the temperature of the specific point (S460). Then, the measurement information is transmitted to the control center (S470).

When a control command is received from the control center (S430) and the control command is a command to detect heat distribution around the target area, the drone 100 detects a thermal image around the target area (S480). Then, the sensing information is transmitted to the control center 200 (S490).

The present invention described above can be implemented as a computer-readable code on a medium on which a program is recorded. The computer-readable medium includes all types of recording devices that store data that can be read by a computer system. Examples of computer-readable media include hard disk drives (HDDs), solid state disks (SSDs), silicon disk drives (SDDs), ROMs, RAM, CD-ROMs, magnetic tapes, floppy disks, optical data storage devices, etc. There is also a carrier wave (for example, transmission over the Internet) also includes the implementation of the form.

If the rotation through hole 631 of the fluid rotating plate 630 is rotated to achieve more than 0 degrees and less than 180 degrees with the upper plate through hole 621 and the lower plate through hole 651 (intermediate distance), the moving distance of the fluid is also It is variable to fit.

The frequency applied by external shock or vibration is inversely proportional to the moving distance of the fluid. That is, in order to control high-frequency vibration, the moving distance of the fluid must be set short, and in order to control the low-frequency vibration, the moving distance of the fluid must be set long.

As described above, in the present invention, since the moving distance of the fluid can be varied by rotating the fluid rotating plate 630, the best buffering effect can be provided in consideration of the surrounding environment or applied vibration.

The elevating case 710 is coupled to the lower portion of the fluid buffer 600 and a space is formed so as to accommodate a fluid therein. The lifting case 710 is formed in a cylindrical shape with an empty inside, and a fluid is accommodated therein.

The elevating rod 720 has an upper end disposed inside the elevating case 710 and can be elevated vertically. The elevating rod 720 is formed in a cylindrical shape with a full inside, and a photographing and measuring unit 130 is coupled to the lower end of the elevating rod 720.

The vertical copper plate 730 is inserted into the lifting rod 720 and disposed between the outer surface of the lifting rod 720 and the inner surface of the lifting case 710 and formed in a ring shape that can move up and down. The inner diameter of the upright copper plate 730 is the same as the outer diameter of the lifting rod 720, and the outer diameter of the upright copper plate 730 is the same as the inner diameter of the lifting case 710.

The upper stopper 721 is formed to protrude from the side of the lifting rod 720 and is disposed above the upright copper plate 730. The lower stopper 722 is formed to protrude from the side of the lifting rod 720 and is disposed at the lower side with respect to the upright copper plate 730. That is, between the upper stopper 721 and the lower stopper 722, the upright copper plate 730 is coupled to be movable up and down.

The upper elastic part 740 is disposed between the lower surface of the upper stopper 721 and the upper surface of the upright copper plate 730, and the lower elastic part 741 is formed between the upper surface of the lower stopper 722 and the upper surface of the upright copper plate 730. It is placed between the lower surfaces. As shown, the vertical copper plate 730 is normally spaced apart from the upper stopper 721 and the lower stopper 722 by a predetermined interval by the elastic force of the upper elastic portion 740 and the lower elastic portion 741.

The rod through hole 750 penetrates the inside of the lifting rod 720 so that a fluid can pass. The rod through hole 750 passes through the elevating rod 720 in the transverse direction and passes through the first transverse through hole 751 and the elevating rod 720 disposed under the upper stopper 721 in the transverse direction, and It is disposed above the lower stopper 722 and penetrates the second transverse through hole 752 and the lifting rod 720 disposed relatively lower than the first transverse through hole 751 in the longitudinal direction, and the first transverse through hole It includes a longitudinal through hole (753) connecting between the 751 and the second transverse through hole (752).

In other words, the first transverse hole 751 is disposed in a space spaced apart between the upper stopper 721 and the upright copper plate 730 in normal times, and in the spaced apart between the lower stopper 722 and the upright copper plate 730 Since the second transverse hole 752 is disposed, the fluid inside the lifting case 710 can freely move up and down.

Meanwhile, the hydraulic pump 760 may be connected to the upper inlet 711 and the lower inlet 712 formed on one side of the lifting case 710 to apply pressure to the fluid inside the lifting case 710. The hydraulic pump 760 may be operated by being electrically connected to a control unit (not shown) or the like.

When the fluid pressure in the lower part of the lifting case 710 is higher than the fluid pressure in the upper part of the lifting case 710 based on the vertical copper plate 730 through the lower inlet 712, the upper elastic part 740 ) Overcomes the elastic force and moves upward to close the first transverse hole 751. In this state, when the upright copper plate 730 moves further upward, the upper surface of the upright copper plate 730 comes into contact with the lower surface of the upper stopper 721, and the lifting rod 720 rises as a whole.

On the contrary, when the fluid pressure in the upper part of the lifting case 710 is higher than the fluid pressure in the lower part of the lifting case 710 based on the upright copper plate 730 through the upper inlet 711, the upright copper plate 730 becomes the lower elastic part. It overcomes the elastic force of 741 and moves downward to close the second transverse hole 752. In this state, when the upright copper plate 730 moves further downward, the lower surface of the upright copper plate 730 comes into contact with the upper surface of the lower stopper 722, and the lifting rod 720 descends as a whole.

When the height of the lifting rod 720 is determined, the hydraulic pump 760 uses the upper inlet 711 and the lower inlet 712 with respect to the lifting plate 730 and the fluid pressure and the lifting case on the upper part of the lifting case 710 (710) In order to maintain the same fluid pressure in the lower portion, the upright copper plate 730 is positioned at a predetermined distance between the upper stopper 721 and the lower stopper 722.

At this time, since both the first transverse hole 751 and the second transverse hole 752 are open, the fluid inside the lifting case 710 can be freely moved, and a buffer effect to some extent is obtained by the movement of the fluid. I can.
