Description

Technical Field

[0001] The utility model relates to the technical field of transmission of image signals and data signals of police unmanned aerial vehicles, and in particular to a balloon-mounted repeater for transmission of images and data of unmanned aerial vehicles. Background Art

[0002] With the rapid development of drones, police unmanned aerial vehicles (UAVs) have been widely used in policing. They have effectively solved previously difficult public security tasks, simplifying complex tasks and generating positive social and economic benefits in a variety of operational tasks, including routine police patrols, counterterrorism and emergency response, forest fire prevention, emergency air defense, drug eradication, large-scale event security, and mass incident management. Police UAVs can quickly reach the scene of an incident. A basic device typically equipped with a camera is responsible for capturing ground-based images and video. This data, combined with the data generated by a back-end image recognition system, is collected and wirelessly transmitted to a ground receiver. Equipped with a high-definition digital camera, they can capture high-quality video and audio of the scene in real time, transmitting the live video information to the command center for immediate assessment and decision-making. This significantly enhances the investigative capabilities of the on-site response team and improves the security and reliability of information acquisition.

[0003] To ensure the operational range of police drones for the aforementioned tasks, it is necessary to ensure stable signal transmission within the jurisdiction of the police force. Currently, police forces lease signal networks from telecommunications operators. However, because these leased signal networks are dedicated to police use, the rental costs are relatively high and are significantly affected by the quality of the telecommunications operator's network signals. Therefore, the applicant proposes establishing a separate local area network for police drones within the police force's jurisdiction to ensure signal transmission for police drones within the jurisdiction. The current police drone local area network is structured to form a number of signal base points within the jurisdiction, using multiple repeaters mounted on balloons connected to the ground via traction ropes. Each signal base point's repeater is able to communicate with ground equipment, and at least the repeaters of two adjacent signal base points are connected to each other. The edges of the jurisdiction are within the communication range of the nearest signal base point's repeater, and the police drone's highest flight altitude is also within the signal range of the repeater above the signal base point.

[0004] Through the networking method described above, a police drone local area network can be established at minimal cost to ensure that the police drones of the police force can maintain signal quality when flying within the jurisdiction.

[0005] However, when using a repeater with this structure, air currents can cause the balloon to drift. Although the balloon is connected to the ground via a traction rope, the movement of the balloon causes the traction rope to swing around the ground connection, forming an angle between the traction rope and the horizontal plane. This changes the attitude of the repeater, and thus the angle of the repeater's antenna. This, in turn, affects signal transmission between the repeater and the police drone, adjacent repeaters, or ground equipment. Therefore, it is necessary to develop a repeater structure to address the above technical problems. Utility Model Content

[0006] The purpose of the utility model is to overcome the shortcomings of the existing technology and provide a balloon-mounted repeater for transmitting drone images and data. The balloon is used to raise the pod equipped with the function of receiving and sending drone image signals and data signals to a level above obstacles such as high-rise buildings or small hills, thereby greatly improving the transmission range and transmission quality of the drone's wireless signal.

[0007] The technical solution adopted by this utility model is:

[0008] A balloon-mounted repeater for transmitting drone images and data includes a pod, wherein a frame A and a frame B are sequentially provided on the outside of the pod. The pod is rotatably connected to frame A via a set of vertical rotating shafts symmetrically arranged at the top and bottom, and the frame A is rotatably connected to frame B via a set of horizontal rotating shafts symmetrically arranged on two opposite sides. The top of the frame B is connected to a traction rope A at the bottom of the balloon via a connecting shaft A, and the bottom of the frame B is connected to a traction rope B fixed to the ground via a connecting shaft B. The vertical rotating shaft is coaxially arranged with the connecting shafts A and B. A battery, a data transmission main control board, a data-to-air transmission antenna, a data-to-ground transmission antenna, an image transmission main control board, an image-to-air transmission antenna, and an image-to-ground transmission antenna are respectively fixed in the pod. The battery is electrically connected to the data-to-air transmission antenna and the data-to-ground transmission antenna respectively via the data transmission main control board, and the battery is electrically connected to the image-to-air transmission antenna and the image-to-ground transmission antenna respectively via the image transmission main control board. The center of gravity of the pod is located at the geometric center of the pod structure.

[0009] A further improved solution of the present invention is that the battery is fixed at the lower part of the pod as a counterweight of the pod.

[0010] A further improvement of the present invention is that an additional counterweight device is provided at the lower part of the interior of the pod.

[0011] A further improved solution of the present invention is that the data-to-ground transmission antenna and the image-to-ground transmission antenna are respectively fixed to the bottom plate in the pod.

[0012] A further improvement of the present invention is that the data air-to-air transmission antenna and the image air-to-air transmission antenna are respectively fixed on the top of the pod.

[0013] A further improvement of the present invention is that the data transmission main control board is a forwarding box supporting the ELRS / mavLink protocol.

[0014] A further improvement of the present invention is that fans are respectively provided on the side walls of two opposite sides of the pod, and the fans are respectively electrically connected to the batteries.

[0015] A further improvement of the present invention is that universal joints are respectively provided at the top of the connecting shaft A and the bottom of the connecting shaft B, and the connecting shaft A is connected to the pulling rope A at the bottom of the balloon through the universal joint, and the connecting shaft B is connected to the pulling rope B fixed to the ground through the universal joint.

[0016] A further improvement of the present invention is that the connection point of the frame A corresponding to the vertical rotating shaft, the connection point of the frame A corresponding to the horizontal rotating shaft, the connection point of the frame B corresponding to the horizontal rotating shaft, the connection point of the frame B corresponding to the connecting shaft A and the connection point of the frame B corresponding to the connecting shaft B are respectively provided with connecting plates.

[0017] The beneficial effects of the present invention are:

[0018] First, the balloon-mounted repeater for drone image and data transmission of the utility model uses a balloon to raise the pod equipped with the function of receiving and sending drone image and data signals to a level above obstacles such as tall buildings or small hills, thereby significantly improving the transmission range and quality of the drone's wireless signal.

[0019] Second, the balloon-mounted repeater for transmitting UAV images and data maintains the vertical stability of the pod through the connection structure between the pod and frames A and B. Even if the pulling ropes A and B form an angle with the horizontal plane, it will only cause frames A and B to tilt, while the pod can still maintain its original posture and the horizontal plane is always in a vertical state.

[0020] Third, the balloon of the present invention is mounted with a repeater for transmitting images and data from drones. The height at which the balloon is lifted off can be directly controlled by the length of a pulling rope B fixed to the ground. It does not require kinetic energy to float in the air and can maintain a long endurance.

[0021] Fourth, the balloon-mounted repeater for UAV image and data transmission of the utility model fixes the battery and additional weight to the lower part of the pod, so that the center of gravity of the pod is located at the lower center of the pod, making it easier to keep the pod stable.

[0022] Fifth, the balloon-mounted repeater for drone image and data transmission of the utility model, through the action of the universal joint, enables the pulling ropes A and B to generate lateral forces on the connecting shafts A and B of the frame B. At the same time, the pulling ropes A and B can be swung quickly and smoothly to the corresponding angles through the rotation of the universal joint, thereby avoiding the pulling ropes A and B from being entangled with the corresponding connecting shafts A and B, thereby generating additional forces and even affecting the rotation of the frame B relative to the frame A and the pod.

[0023] Sixth, the balloon-mounted repeater for UAV image and data transmission of the utility model reduces the stress generated by the rotating shaft or the connecting shaft on the corresponding connection of frame A or the corresponding connection of frame B through the action of the connecting plate, thereby improving the service life of frame A and frame B.

[0024] Seventh, the balloon-mounted repeater for transmitting UAV images and data of the utility model ensures the quality of data signals and image signals transmitted to UAVs or ground equipment through the positions of the sky transmission antenna and the ground transmission antenna set in the pod.

[0025] Eighth, the balloon-mounted repeater for transmitting UAV images and data, and the fans provided on the side walls on two opposite sides of the pod create penetrating wind in the pod, thereby effectively ventilating and cooling the pod. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Figure 1 This is a three-dimensional schematic diagram of the present application.

[0027] Figure 2 This is a schematic diagram of the structure inside the pod. DETAILED DESCRIPTION

[0028] Combine Figure 1 and Figure 2It can be seen that the repeater for transmitting drone images and data mounted on the balloon includes a pod 1, and the outer side of the pod 1 is provided with a frame A2 and a frame B3 in sequence. The pod 1 is rotatably connected to the frame A2 through a set of vertical rotating shafts 4 symmetrically arranged at the top and bottom, and the frame A2 is rotatably connected to the frame B3 through a set of horizontal rotating shafts 5 symmetrically arranged on two opposite sides. The top of the frame B3 is connected to the traction rope A at the bottom of the balloon through a connecting shaft A6, and the bottom of the frame B3 is connected to the traction rope B fixed to the ground through a connecting shaft B7. The vertical rotating shaft 4 is connected to the connecting shaft A6 and the connecting shaft B 7 are coaxially arranged, and a battery 10, a data transmission main control board 11, a data-to-air transmission antenna 12, a data-to-ground transmission antenna 13, an image transmission main control board 14, an image-to-air transmission antenna 15, and an image-to-ground transmission antenna 16 are fixed in the pod 1 respectively. The battery 10 is electrically connected to the data-to-air transmission antenna 12 and the data-to-ground transmission antenna 13 respectively through the data transmission main control board 11, and the battery 10 is electrically connected to the image-to-air transmission antenna 15 and the image-to-ground transmission antenna 16 respectively through the image transmission main control board 14. The center of gravity of the pod 1 is located at the geometric center of the pod 1 structure.

[0029] By using balloons, the pod 1 equipped with a device for receiving and sending image and data signals from the drone is raised above obstacles such as tall buildings or small hills, thereby significantly improving the transmission range and quality of the drone's wireless signals.

[0030] Air currents cause the balloon to move, causing the traction cord A connecting the balloon to pod 1 and the traction cord B connecting pod 1 to the ground to lose their vertical alignment, creating an angle between the horizontal plane and their fixed point on the ground. This causes pod 1 to tilt, and in turn, the transmission antenna inside pod 1 to tilt as well, affecting signal transmission. The connection structure between pod 1 and frames A2 and B3 maintains pod 1's vertical stability. Even if traction cords A and B create an angle with the horizontal plane, only frames A2 and B3 will tilt, while pod 1 remains in its original position, maintaining a vertical position.

[0031] The height to which the balloon rises can be directly controlled by the length of the pulling rope B fixed to the ground. It does not require kinetic energy to float in the air and can maintain long-term endurance.

[0032] The pod 1 is always kept perpendicular to the horizontal plane only by the action of gravity. The connection structure with the frame A and the frame B is simple and there is no need to control the posture of the pod 1 through electronic equipment, which reduces costs and reduces the possibility of failure.

[0033] The battery is fixed at the lower part of the pod 1 as a counterweight of the pod 1 .

[0034] An additional counterweight device is also provided at the lower part of the interior of the pod 1 .

[0035] The data-to-ground transmission antenna 13 and the image-to-ground transmission antenna 16 are respectively fixed to the bottom plate in the pod 1 .

[0036] The data air transmission antenna 12 and the image air transmission antenna 15 are respectively fixed on the top of the pod 1.

[0037] The data transmission main control board 11 is a forwarding box that supports the ELRS / mavLink protocol.

[0038] Fans 17 are respectively provided on the side walls of two opposite sides of the pod 1 , and the fans 17 are respectively electrically connected to the batteries 10 .

[0039] The fans 17 provided on the side walls of the two opposite sides of the pod 1 form penetrating wind in the pod 1 .

[0040] Universal joints 8 are provided at the top of the connecting shaft A6 and the bottom of the connecting shaft B7 respectively. The connecting shaft A6 is connected to the pulling rope A at the bottom of the balloon through the universal joint 8, and the connecting shaft B7 is connected to the pulling rope B fixed to the ground through the universal joint 8.

[0041] The connection point of the frame A2 corresponding to the vertical rotation axis 4, the connection point of the frame A2 corresponding to the horizontal rotation axis 5, the connection point of the frame B3 corresponding to the horizontal rotation axis 5, the connection point of the frame B3 corresponding to the connecting axis A6 and the connection point of the frame B3 corresponding to the connecting axis B7 are respectively provided with connecting plates 9.

[0042] The surface of the pod 1 is dustproof and waterproof, and water retaining devices are provided on the side walls of the pod 1 at positions corresponding to the fans 17 , to prevent water from entering the pod 1 from the fans 17 .

[0043] In this embodiment, the data transmission main control board 11 adopts the data transmission main board of model Goggles2 produced by DJI; the data air transmission antenna 12 and the data ground transmission antenna 13 adopt the HWAP20 produced by Libituo; the image transmission main control board 14 adopts the image transmission main board of model story-sc60 produced by Suzhou Siturui; the image air transmission antenna 15 and the image ground transmission antenna 16 adopt DJI's O3 sky terminal.

[0044] When used in this application, the data transmission main control board 11 receives ground data signals emitted by ground equipment through the data-to-ground transmission antenna 13, and transmits the ground data signals to the drone located above the pod 1 through the data-to-air transmission antenna 12. The data transmission main control board 11 can also receive feedback data signals from the drone located above the pod 1 through the data-to-air transmission antenna 12, and transmit the feedback data signals to the ground equipment through the data-to-ground transmission antenna 13. The image transmission main control board 14 receives image acquisition signals emitted by the drone located above the pod 1 through the image-to-air transmission antenna 15, and transmits the image acquisition signals to the ground equipment through the image-to-ground transmission antenna 16. The image transmission main control board 14 can also receive image feedback signals emitted from the ground through the image-to-ground transmission antenna 16, and transmit the image feedback signals to the drone located above the pod 1 through the image-to-air transmission antenna 15. In addition, during use, the vertical rotation shaft 4 and the horizontal rotation shaft 5 ensure that the pod 1 is always stably perpendicular to the horizontal plane under the action of gravity, regardless of the posture of the frame A2 and the frame B3, thereby effectively ensuring the stability of the relay transmission of data signals and image signals.
