The tributary sluice control unit 130 may control the tributary sluice gate 120 to open and close.

The tributary sluice gate 120 is a sluice gate installed at a tributary that meets the downstream of the dam, and can prevent flooding in a low area as the downstream flows back into the tributary according to the water level that rises when the dam is discharged.

The tributary sluice gate 120 may be implemented by hydraulic or electric type, and the hydraulic or electric tributary sluice gate 120 may be embodied as various known types of sluice gates, and thus a detailed description thereof will be omitted.

An image processing method may be used.

In particular, when the tributary sluice gate 120 is detected, the detection unit may also detect the open/closed state of the tributary sluice gate 120 . For example, the detection unit may detect the opening/closing state of the tributary sluice gate 120 based on the upper and lower positions of the tributary moisture in the detected tributary sluice gate 120 or the position of the rack gear unit 121 .

The information detected by the detection unit may be provided to the dam management server 115 through the wireless communication module.

When the unmanned aerial vehicle 150 receives the open signal from the dam management server 115 through the wireless communication module and a person is detected in the image taken, the water level may increase according to the opening of the dam sluice gate 113.

When a person is photographed, a warning is broadcast Alternatively, the tributary sluice gate 120 is closed by checking the opening of the other tributary sluice gate 120 .

Therefore, the dam downstream safety management system 100 using the unmanned aerial vehicle 150 according to an embodiment of the present invention can manage the downstream of the dam by shooting while the unmanned aerial vehicle 150 flies downstream of the dam. , when a person is photographed from the unmanned aerial vehicle 150 when the dam sluice gate 113 is opened, a warning broadcast for evacuation can be performed to prevent the occurrence of a safety accident.

In addition, when the dam sluice gate 113 is opened, the dam management server 115 sends an opening signal and closes the tributary sluice gate 120 through the automatic opening and closing unit 131, thereby preventing flood damage due to backflow in the downstream area. In addition, when the tributary sluice gate 120 is not closed, the unmanned aerial vehicle 150 flies to the tributary sluice gate 120 and controls the manual opening and closing unit 134 through the sluice gate driving unit 155 to open the tributary sluice gate 120 . By closing it, it is possible to prevent flood damage due to backflow in the downstream area.

In addition, the pillar station 140 is formed in the shape of a polygonal pillar, and the unmanned aerial vehicle 150 has a coupling cover unit 158 inserted into the pillar station 140 is installed to operate the manual opening and closing unit 134 with a driving motor 156 . When operated by the unmanned aerial vehicle 150 rotates in the pillar station 140 to prevent loss of power transmission, as well as a cover hopper part 159 is installed at the lower end of the coupling cover part 158 to install the unmanned aerial vehicle 150 . When the 150 is seated on the pillar station 140 , the unmanned aerial vehicle 150 can be easily seated while the cover hopper unit 159 is guided to the pillar station 140 .

In the above, embodiments of the present invention have been described, but the scope of the present invention is not limited thereto, and it is easily changed by those of ordinary skill in the art to which the present invention pertains from the embodiments of the present invention and recognized as equivalent. including all changes and modifications to the scope of
