[0037] Figure 1 and Figure 2 is a diagram showing the configuration of a CCTV control system using a drone according to an embodiment of the present invention, Figure 3 is a diagram showing the configuration of a first rotating device and a second rotating device according to an embodiment of the present invention.

[0038] The CCTV control system 100 using a drone according to an embodiment of the present invention includes a CCTV camera device 110, a drone station 131, a drone 140, a control device 160, and a control server 170.

[0039] At the upper end of the utility pole 10, there is a bracket 20 of a specified length extending horizontally along the utility pole 10. On one side of the upper surface of the bracket 20, there are a CCTV (Closed Circuit Television) camera device 110 and a wireless drone charging system 130.

[0040] The CCTV camera device 110 includes a camera housing 111 of a specified shape carrying a camera head 110a for photographing a target object, a camera bracket 112 formed at the lower part of the camera head 110a and vertically erected, a camera base 113 formed at the lower part of the camera bracket 112 for fixing the camera bracket 112, and a camera rotating plate 115 for mounting the camera base 113 on the upper surface.

[0041] At the lower part of the camera rotating plate 115 of the CCTV camera device 110, a first rotating device 114 is coupled, enabling the camera rotating plate 115 to rotate 360 degrees in the left - right direction, and thus the camera head 110a can also rotate 360 degrees.

[0042] The first rotating device 114 is configured such that a first rotating rod 116 of a certain length is coupled to the lower part of the camera rotating plate 115, a first bevel gear 117 is coupled to the lower end of the first rotating rod 116, a second bevel gear 118 meshes with the first bevel gear 117 in the vertical direction, and the second bevel gear 118 is coupled to the first rotating shaft 119 of the first driving motor 119a.

[0043] The first rotating device 114 drives the second bevel gear 118 and the first bevel gear 117 to rotate through the first driving motor 119a. Thus, the camera rotating plate 115 rotates with the rotation of the first rotating rod 116 coupled to the first bevel gear 117. Then, through the first rotating device 114, the camera head 110a coupled to the camera bracket 112 rotates 360 degrees in the left - right direction with the rotation of the camera rotating plate 115.

[0044] The CCTV camera device 110 further includes an auxiliary housing 121, which is coupled to one side surface of the camera housing 111 and forms an internal space portion.

[0045] A second rotating device 120 is formed in the internal space portion of the auxiliary housing 121, and the CCTV camera device 110 can rotate in the up - down direction through the second rotating device 120.

[0046] The second rotating device 120 is configured such that a second camera rotating rod 122 of a specified length is coupled to one surface of the camera housing 111, a third bevel gear 123 is coupled to one end of the second camera rotating rod 122 on one side, a fourth bevel gear 124 meshes with the third bevel gear 123 in the vertical direction, and the fourth bevel gear 124 is coupled to a second rotating shaft 125 of the second driving motor 126.

[0047] The second rotating device 120 rotates the fourth bevel gear 124 and the third bevel gear 123 by driving of the second driving motor 126. Thus, the second camera rotating rod 122 rotates as the second rotating rod 125 coupled to the fourth bevel gear 124 rotates. Subsequently, the camera housing 111 is rotated in the up and down direction as the second camera rotating rod 122 rotates by the second rotating device 120.

[0048] In the CCTV camera device 110, the camera focusing direction of the camera head 110a is inclined at a specified angle to face the ground, so that a target object can be photographed.

[0049] The CCTV camera device 110 rotates the camera head 110a upward by the second rotating device 120 so that the camera head 110a is aligned with the horizontal direction, and rotates the camera head 110a 360 degrees by the first rotating device 114 so that the camera head 110a faces the side of the drone station 131. The CCTV camera device 110 can track the drone 140 and monitor whether the drone 140 lands smoothly on the drone station 131.

[0050] Figure 4 It is a diagram showing a device connected to the internal configuration of a control device according to an embodiment of the present invention.

[0051] The control device 160 according to an embodiment of the present invention includes a communication unit 161, a video storage unit 162, a control unit 163, an object detection unit 164, and an object tracking unit 165, and the control unit 163 is electrically connected to the camera head 110a, the first driving motor 119a, and the second driving motor 126.

[0052] After the camera head 110a photographs a target object and generates video information, the video information is sent to the control unit 163.

[0053] The control unit 163 periodically stores the photographed video information in the video storage unit 162, and can send the video information stored in the video storage unit 162 including the camera ID to the control server 170 through the communication unit 161.

[0054] The object detection unit 164 collects video frames (including video information of human objects) obtained from the video storage unit 133, extracts the feature map of the video frames using YOLOv8 (human recognition algorithm), and based on the extracted feature map, extracts at least one region where a human object is estimated to exist from the video.

[0055] The object detection unit 164 uses any one of the neural networks in Deep Neural Networks (DNN), Convolutional deep Neural Networks (CNN), Recurrent Neural Network (RNN), and Deep Belief Networks (DBN) to extract the feature map from the input video.

[0056] The object detection unit 164 can use a model that has been learned by the learning unit through deep learning to generate the feature map. Deep learning is defined as a collection of machine learning algorithms that attempt high-level abstractions (Abstractions, the task of summarizing the core content or functions from a large amount of data or complex materials) through a combination of various nonlinear transformation techniques.

[0057] The object detection unit 164 extracts the region where a human object is estimated to exist from the video frame, and extracts the feature map representing the features from the extracted region.

[0058] Based on the extracted feature map, the object detection unit 164 extracts at least one region where a human object is estimated to exist from the video. Methods for extracting regions can include, for example, faster Region-based Convolutional Neural Network (faster RCNN), Single Shot MultiBox Detector (SSD), YOLO (You Only Look Once), etc. In this invention, the YOLO object recognition module (YOLOv8) is used as an example.

[0059] The object detection unit 164 can select the feature map including the coordinates of the class of each region of the video from the feature map, identify the coordinates for distinguishing the region from the selected feature map, and then extract the identified coordinates as the region where the object is estimated to exist.

[0060] The object detection unit 164 can set one or more than two human objects.

[0061] The object detection unit 164 can display each of the at least one extracted region as a bounding box around the outermost edge of the human object.

[0062] Each bounding box indicates the possibility of the presence of a human object at the position of the corresponding bounding box in the video.

[0063] The YOLOv8 model uses a single network architecture to predict the class probabilities and corresponding bounding boxes of the entire input video.

[0064] The object tracking unit 165 receives, for each video frame including a human object continuously received from the object detection unit 164, multiple bounding box information as the human object detection result, and generates and stores it as a collection information table for the received multiple bounding box information.

[0065] Among them, the bounding box information may include human object coordinate information, recognition result, and recognition probability.

[0066] The object tracking unit 165 receives one or more pieces of bounding box information from the object detection unit 164, and for each video frame detected from the moving human object, tracks the tracking object and coordinate information of the target human object belonging to the bounding box information.

[0067] When there are multiple target human objects in the same scene (video frame), the object tracking unit 165 tracks the bounding box information of each target human object by executing a human object tracking algorithm for tracking each target human object for each video frame.

[0068] A video frame is a frame continuously detected from a moving object.

[0069] Since it is a moving object, the bounding box coordinate information continuously changes, and based on this, the object tracking unit 165 calculates multiple human object recognition results.

[0070] The control unit 163 periodically stores the bounding box information of the object tracking unit 165 in the video storage unit 162, and can send the bounding box information stored in the video storage unit 162 to the control server 170 through the communication unit 161.

[0071] The control unit 163 controls the first drive motor 119a and the second drive motor 126 according to the drone monitoring mode, so that the camera head 110a rotates through the second rotating device 120 to align with the horizontal direction, and controls the camera head 110a to rotate 360 degrees through the first rotating device 114 to face the drone station 131 side. The control unit 163 can capture the scene of the drone 140 landing on the drone station 131 through the camera head 110a and send it to the control server 170 through the communication unit 161.

[0072] The control unit 163 generates coordinate information of the target object by using the object detection unit 164 and the object tracking unit 165. When the target object (human object) leaves the monitoring area captured by the camera head 110a, it generates a drone drive signal and sends the signal to the drone station control module 180, and the generated drone drive signal can be sent to the control module 150 mounted on the drone 140 through the drone station control module 180. Then, the drone 140 can move towards the coordinate information of the target object according to the control of the processing unit 154 and capture the target object through the camera module 145.

[0073] Figure 5 FIG. is a diagram showing the configuration of a drone station according to an embodiment of the present invention. Figure 6 FIG. is a diagram showing a state in which the cover wing part is folded flat to open or erected to close in the drone station according to an embodiment of the present invention. Figure 7 FIG. is a diagram showing the detailed configuration of the cover part according to an embodiment of the present invention.

[0074] The wireless drone charging system 130 may further include a drone station 131 and a drone 140.

[0075] The drone station 131 is a landing platform for the takeoff and landing of the drone 140, is formed at a certain height from the bottom surface, and has a circular-shaped station body 132 with an internal space part. The drone station 131 includes: a circular bottom placement part 132a formed at the upper central part of the station body 132 and on which the drone 140 is placed; a plurality of cover wing parts formed radially along the edge of the bottom placement part 132a; and a cover part 133. The plurality of cover wing parts are unfolded to open the space of the bottom placement part 132a, or the unfolded plurality of cover wing parts are erected to close the space of the bottom placement part 132a.

[0076] The cover part 133 according to an embodiment of the present invention can be formed by the overlap of a plurality of cover wing parts radially centered on the bottom placement part 132a.

[0077] Each cover wing part is curved gently towards the bottom placement part 132a, protrudes towards the outer direction, and is formed to have a predetermined width and length, and has a shape that gradually narrows from the upper end to the lower end.

[0078] In the cover part 133, the edge part of the first-first cover wing part 134a is stacked on the outer part of the first-second cover wing part 134b, and the edge part of the first-second cover wing part 134b is stacked on the outer part of the first-third cover wing part 134c.

[0079] In the cover portion 133, the edge portions of the first to third cover wing portions 134c are stacked on the outer portions of the second to first cover wing portions 135a, the edge portions of the second to first cover wing portions 135a are stacked on the outer portions of the second to second cover wing portions 135b, and the edge portions of the second to second cover wing portions 135b are stacked on the outer portions of the second to third cover wing portions 135c.

[0080] In the cover portion 133, the edge portions of the second to third cover wing portions 135c are stacked on the outer portions of the third to first cover wing portions 136a, the edge portions of the third to first cover wing portions 136a are stacked on the outer portions of the third to second cover wing portions 136b, and the edge portions of the third to second cover wing portions 136b are stacked on the outer portions of the third to third cover wing portions 136c.

[0081] Depending on the situation, protrusions are formed on the outer portions of at least one of the cover wing portions in the cover portion 133 so that when the drone station 131 is closed, the upper hole 133h can be sealed. It can be formed only on a part of the plurality of cover wing portions.

[0082] As Figure 5 shown, in the cover portion 133, a protrusion 135c-1 is formed on the outer edge portion of the second to third cover wing portion 135c. When the drone station 131 is closed, the protrusion 135c-1 can perform the function of sealing the upper hole 133h. However, the protrusion can also be formed on other cover wing portions and can be omitted depending on the situation.

[0083] The opening of the drone station 131 means that the plurality of cover wing portions are laid flat so that the drone 140 lands on the bottom placement portion 132a. To achieve this process, the plurality of cover wing portions can be radially expanded with the bottom placement portion 132a as the center.

[0084] The closing of the drone station 131 is that the plurality of cover wing portions are erected and concave to enclose the space, so that the drone 140 is placed inside. To achieve this operation, the drone station 131 can be configured such that each cover wing portion expanded with the bottom placement portion 132a as the center is erected, the specified areas between the cover wing portions overlap each other, and at the same time the edges gather at the inner center to enclose the space, thereby storing the drone 140 inside.

[0085] The bottom placement portion 132a is circular and is the position for the takeoff and landing of the drone 140. A wireless charging portion 182 is formed on its inner surface, so that the drone 140 can be charged through a wireless signal.

[0086] The bottom placement portion 132a is spaced apart by a specified interval in the circumferential direction along the edge, and the first rotating curve rod 138a, the second rotating curve rod 138b, and the third rotating curve rod 138c of a specified length are provided at a predetermined interval.

[0087] The first rotating curved rod 138a, the second rotating curved rod 138b, and the third rotating curved rod 138c are bent to correspond to the edge shape of the bottom placement part 132a and can be bent into a cylindrical shape.

[0088] The first cover wing part 134a, the second cover wing part 134b, and the third cover wing part 134c are respectively combined with the first wing connection part 137a of a specified length.

[0089] The first wing connection part 137a of the first cover wing part 134a, the first wing connection part 137a of the second cover wing part 134b, and the first wing connection part 137a of the third cover wing part 134c are connected to the first rotating curved rod 138a in the length direction. As the first rotating curved rod 138a rotates, the first cover wing part 134a, the second cover wing part 134b, and the third cover wing part 134c can also rotate together.

[0090] The second cover wing part 135a, the second cover wing part 135b, and the second cover wing part 135c are respectively combined with the second wing connection part 137b of a specified length.

[0091] The second wing connection part 137b of the second cover wing part 135a, the second wing connection part 137b of the second cover wing part 135b, and the second wing connection part 137b of the second cover wing part 135c are connected to the second rotating curved rod 138b in the length direction. As the second rotating curved rod 138b rotates, the second cover wing part 135a, the second cover wing part 135b, and the second cover wing part 135c can also rotate together.

[0092] The third cover wing part 136a, the third cover wing part 136b, and the third cover wing part 136c are respectively combined with the third wing connection part 137c of a specified length.

[0093] The third wing connection part 137c of the third cover wing part 136a, the third wing connection part 137c of the third cover wing part 136b, and the third wing connection part 137c of the third cover wing part 136c are connected to the third rotating curved rod 138c in the length direction. As the third rotating curved rod 138c rotates, the third cover wing part 136a, the third cover wing part 136b, and the third cover wing part 136c can also rotate together.

[0094] The first rotating curved rod 138a, the second rotating curved rod 138b, and the third rotating curved rod 138c can be respectively combined with a wing rotating unit 139 that rotates the rotating curved rod at one end on one side.

[0095] Figure 8It is a diagram showing the detailed configuration of the wing rotation unit according to an embodiment of the present invention.

[0096] In each wing rotation unit 139, the first rotating curved rod 138a, the second rotating curved rod 138b, and the third rotating curved rod 138c are respectively coupled to the first gear 139a at one end, and the second gear 139b meshes with the first gear 139a in the vertical direction, and the second gear 139b is coupled to the third rotating shaft 139c of the third drive motor 139d.

[0097] In each wing rotation unit 139, the second gear 139b and the first gear 139a rotate as the third drive motor 139d is driven. Thus, the cover wing rotates as the first rotating curved rod 138a, the second rotating curved rod 138b, and the third rotating curved rod 138c, which are respectively coupled to the first gear 139a, rotate.

[0098] In other words, the wing rotation unit 139 rotates the first wing connection part 137a by the rotation of the first rotating curved rod 138a and drives the 1-1 cover wing part 134a, the 1-2 cover wing part 134b, and the 1-3 cover wing part 134c coupled to the first wing connection part 137a to rotate together, whereby it can be folded flat or erected.

[0099] The wing rotation unit 139 rotates the second wing connection part 137b by the rotation of the second rotating curved rod 138b and drives the 2-1 cover wing part 135a, the 2-2 cover wing part 135b, and the 2-3 cover wing part 135c coupled to the second wing connection part 137b to rotate together, whereby it can be folded flat or erected.

[0100] The wing rotation unit 139 rotates the third wing connection part 137c by the rotation of the third rotating curved rod 138c and drives the 3-1 cover wing part 136a, the 3-2 cover wing part 136b, and the 3-3 cover wing part 136c coupled to the third wing connection part 137c to rotate together, whereby it can be folded flat or erected.

[0101] Figure 9 It is a diagram showing a cross-section of the bottom placement part and the cover part according to an embodiment of the present invention.

[0102] The bottom placement part 132a is recessed in the central part of the upper surface of the station body 132.

[0103] When the drone 140 is placed on the upper surface of the station body 132, by configuring the height of the bottom placement part 132a to be lower than the height of the cover part 133, the drone 140 can be moved toward the bottom placement part 132a side.

[0104] A drain port 132b may be formed at the central part of the bottom placement part 132a for draining water.

[0116] The processing unit 154 controls in such a way as to charge the rechargeable battery 151 with the power information received from the first wireless power receiving unit 146 or the second wireless power receiving unit 147.

[0117] The rechargeable battery 151 can store and supply the power required for the flight and driving of the drone 140.

[0118] The GPS module 152 receives the coordinate information of the drone 140 from artificial satellites to calculate the current position.

[0119] When the drone 140 is flying outdoors, the GPS module 152 can measure the coordinate values.

[0120] The sensor module 155 can include an ultrasonic sensor, an acceleration sensor, a laser distance measurement sensor, etc. When the sensor module 155 is an ultrasonic sensor, by measuring the distance to the surrounding objects of the drone 140, the drone 140 can avoid obstacles when flying outdoors, or calculate the three-dimensional coordinates of the drone during the process of landing on the drone station 131.

[0121] When the sensor module 155 is an acceleration sensor, the value for controlling the balance of the drone 140 during flight, takeoff, and landing is calculated by measuring the acceleration change of the drone 140 in a specific direction. When the sensor module 155 is a laser distance measurement sensor, the drone 140 can avoid obstacles during flight by measuring the distance to the surrounding objects of the drone 140 or to the drone station 131, or calculate the three-dimensional coordinates of the drone 140 during the process of taking off from the drone station 131 and landing on the drone station 131.

[0130] The sensor unit 183 includes an ultrasonic sensor, a video processing sensor, a laser distance measurement sensor, etc., and can measure the distance from the UAV 140, and can finely adjust the takeoff and landing of the UAV 140 through the measurement results.

[0131] When the UAV 140 that has ended its flight and is landing approaches the UAV station 131, the sensor unit 183 can make the UAV 140 land at the correct charging position by detecting the position of the UAV 140 and the distance from the UAV 140.

[0132] The workstation controller 181 can send and receive signals and data with the wireless communication module 153 of the unmanned aerial vehicle 140 through the workstation communication module 185.

[0133] The workstation controller 181 controls the overall operation of the unmanned aerial vehicle station 131.

[0134] When the workstation controller 181 detects the approach of the unmanned aerial vehicle 140, it guides the unmanned aerial vehicle 140 to land at the correct position of the hole to be landed by generating the current position information and sending it to the unmanned aerial vehicle 140, or supplies the power of the power supply unit 184 to the unmanned aerial vehicle 140 through the wireless charging unit 182 to charge the charging battery 151 of the unmanned aerial vehicle 140, or can also control the flight of the unmanned aerial vehicle so that the unmanned aerial vehicle 140 that has completed charging takes off to execute the next instruction.

[0135] The workstation controller 181 is electrically connected to the third drive motor 139d to send an electrical signal to the third drive motor 139d, and drives the second gear 139b and the first gear 139a to rotate through the drive of the third drive motor 139d. Therefore, the cover wing part rotates as the first rotary curve rod 138a, the second rotary curve rod 138b, and the third rotary curve rod 138c respectively combined with the first gear 139a rotate. After that, the plurality of cover wing parts are unfolded to open the space of the bottom placement part 132a, or the plurality of unfolded cover wing parts 132a are erected to close the space of the bottom placement part 132a.

[0136] Figure 14 and Figure 15 FIG. is a diagram showing a radiation beam pattern when the cover wing part according to an embodiment of the present invention is configured as an antenna device.

[0137] As another embodiment, the cover wing parts of the cover 133 can be configured as a plurality of antenna devices.

[0140] The workstation controller 181 periodically receives position information from the take-off unmanned aerial vehicle (UAV) 140 through the workstation communication module 185, determines the moving direction of the UAV 140 by analyzing the received position information, and increases the current intensity of the feeding part of the cover wing part corresponding to the moving direction of the UAV 140 by controlling the power supply unit 184. Therefore, by concentrating the radiation size of the electromagnetic wave in the moving direction of the corresponding UAV 140, the directivity is improved, and thus the effect of increasing the antenna gain is achieved. Therefore, the wireless communication efficiency between the workstation controller 181 and the UAV 140 can be improved.

[0141] Figure 16 It is a diagram showing a UAV monitoring method executed when an object leaves the monitoring coverage area of a UAV station according to an embodiment of the present invention.

[0142] Each UAV station 131 presets its own monitoring coverage area, and the control server 170 registers and manages each UAV station 131 and UAV 140.

[0143] The control server 170 receives and monitors the current position information of each UAV 140 from each UAV station 131, and when an object leaves the monitoring coverage area, it can generate a UAV return instruction signal and send it to the corresponding UAV 140.

[0144] When receiving the UAV return instruction signal from the control server 170, the UAV 140 moves to its respective UAV station 131.

[0145] The control server 170 generates a UAV movement signal including the object position information and sends it to the UAV station 131 responsible for the monitoring coverage area where the object has moved. This UAV station 131 can move the UAV 140 to the object according to the UAV movement signal and perform flight tracking.
