[0002] With rapid urban development and a surge in private vehicle ownership, traffic management workloads are increasingly heavy. Simultaneously, to improve management efficiency, traffic management departments have a growing need to acquire road traffic information via video and to record road traffic conditions using mobile video equipment. Surveillance cameras, being semiconductor imaging devices, offer advantages such as high sensitivity, resistance to strong light, low distortion, small size, long lifespan, and vibration resistance. They are installed at various intersections in cities to monitor traffic conditions in real time, facilitating the acquisition of traffic information and the recording of traffic violations. However, with the increasing complexity of traffic conditions, the coverage of existing roadside surveillance cameras and dedicated monitoring equipment is limited, resulting in numerous video surveillance blind spots and blind spots for dedicated monitoring equipment. Adding new traditional video surveillance or dedicated monitoring equipment is not only costly but also limited to single, fixed locations, failing to meet the current complex and ever-changing traffic management needs.

[0009] To make the objectives, technical solutions, and advantages of the embodiments of this patent clearer, the technical solutions of the embodiments of this patent will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this patent, not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0010] like Figures 1-2 As shown, this application includes a lightweight unmanned aerial vehicle (UAV) device with omnidirectional traffic movement monitoring capabilities, comprising a UAV 1, a parking platform 3, a rotating device 4, and a fixing device 6.

[0011] A monitoring camera is installed on the drone 1; a parking platform 3 is installed on the rotating device 4; a fixing device 6 is provided at the bottom of the rotating device 4 and is installed on the pole through the fixing device 6; the drone 1 with the height-adjusting bracket 2 installed is parked on the parking platform 3; the rotating device 4 rotates and drives the parking platform 3 to rotate, thereby driving the drone 1 on the parking platform 3 to perform 360-degree monitoring.

[0012] The rotating device 4 in this application can be installed on various types of cantilever poles in existing road infrastructure, such as light poles or traffic light poles, using a fixing device. The parking platform 3 is a circular platform with two concentric rings of landing aids, providing reference assistance for the drone operator when landing on the platform. The drone 1 is operated by the operator to land on the parking platform 3, extending the drone's endurance and enabling it to operate for extended periods. When needed, the rotating device 4 drives the parking platform 3 to rotate, thereby causing the drone 1 on the parking platform 3 to rotate 360 ​​degrees, allowing for real-time monitoring and return of the surrounding traffic conditions via a surveillance camera. When the drone needs to take off to investigate vehicle behavior or traffic conditions at a distance, it can be remotely activated to take off from the parking platform 3.

[0013] like Figure 3 and Figure 4 As shown, the rotating device 4 includes: a housing 41, a drive motor 42, a driving gear 43, a driven gear 44, a turntable shaft 45, and a power supply 47. The housing 41 has a ventilation opening 46. The drive motor 42, driving gear 43, and driven gear 44 are disposed within the housing 41. The bottom of the turntable shaft 45 is rotatably disposed within the housing 41, and its top passes through the top cover of the housing 41 to connect to the parking platform 3. The driving gear 43 is fixedly disposed at the output end of the drive motor 42. A rotatable turntable shaft 45 is disposed on one side of the driving gear 43, and the top of the turntable shaft 45 is connected to the parking platform 3. The driven gear 44 is sleeved on the turntable shaft 45 and meshes with the driving gear 43. The power supply 47 is located on one side of the drive motor 42 and supplies power to the drive motor 42.

[0014] When in use, the drive motor 42 starts and drives the drive gear 43 to rotate. The driven gear 44, which meshes with the drive gear 43, rotates synchronously, thereby driving the turntable shaft 45 to rotate and the parking platform 3 to rotate.

[0015] To further enhance practicality, the drive motor 42 is selected to be a motor capable of forward or reverse rotation via remote control. For example, the drive motor can be controlled to rotate forward or reverse using a radio frequency remote control, an infrared remote control, or similar methods. The remote control is fixed to the drone's remote control handle. When detection in a specific direction is required, the remote control controls the rotation device to rotate the drone in the corresponding direction, capturing images and providing real-time traffic updates. Adjusting the rotation device using the remote control ensures accurate manual adjustment of the drone's camera direction on the parking platform according to actual usage needs. The method of controlling the stepper motor's forward and reverse rotation via remote control signals can be implemented using existing technology.

[0016] The rotating device 4 also includes a power supply 47, which is located on one side of the drive motor 42 and supplies power to the drive motor 42.

[0017] In this embodiment, to improve practicality, a waterproof drive motor 42 and a gear set are used. This application achieves rotation through the drive motor and gear set, resulting in a simple overall structure that can be integrated into a housing. Its compact size ensures that the rotating device 4 can be stably mounted on the light pole, preventing it from falling off. This allows the drone to rotate 360 ​​degrees while temporarily parked, providing unobstructed views in all directions.

[0018] like Figure 5 As shown, this application also includes a solar panel 5 and a solar panel bracket 7. The solar panel 5 is mounted on the solar panel bracket 7 and connected to a power supply 47 to store electricity for the power supply 47. By using the solar panel to supply power, the rotating device can be used for a long time. The solar panel, the power supply supporting the charging of the solar panel, and the charging circuit are all based on existing technologies.

[0019] To provide the monitoring camera of the drone parked on the parking platform 3 with a wider field of view and to prevent the camera lens from being obstructed by the edge of the rotating platform when the drone is parked, this application also provides a height-adjusting bracket 2 for the drone. The height-adjusting bracket 2 includes: drone tripod 21 and fixing cable 22. The drone tripod 21 is located below the fixing cable 22, and the fixing cable 22 is mounted on the drone's fuselage.

[0020] Figure 6 In the embodiment shown, the drone tripod 21 includes a support plate that can be placed flat on the ground. There are heightening rods on both sides of the support plate, and a flat plate on the heightening rod that contacts the drone. There is a fixing sling 22 on the flat plate. During installation, the fixing sling 22 is opened and placed at the bottom of the drone. Then, the fixing sling 22 is pulled from both sides of the drone to the top of the drone, the fixing sling 22 is fastened, and the length of the sling is adjusted according to the drone model to fix the drone, thereby installing the heightening bracket 2 on the drone.

[0021] In actual use, before the drone takes off, the operator manually installs the extension bracket 2 onto the drone and remotely controls the drone to take off and complete the flight mission. When parking is required, the drone with the extension bracket 2 installed is controlled to park on the parking platform 3. By setting up the extension bracket 2, the camera is prevented from being blocked by the parking platform when the drone is temporarily parked on the platform, thus avoiding limiting the downward angle of the lens.

[0022] like Figure 7As shown, the fixing device 6 includes a fixing ring 61 and a screw 62; the top of the ring 61 is fixed to the bottom of the housing 41, and the bottom of the ring 61 is fixedly connected to the rod body by the screw 62. In this embodiment, the fixing device consists of four semi-circular rings, respectively located on both sides of the bottom of the rotating device, with two rings on one side. The rings can fit snugly against the rod body, and the screws are used to fix the rings to the rod body, which is not only firm but also convenient for disassembly.

[0023] The overall usage process of this device is as follows: The parking platform is installed on the rotating device, which is then fixed to the signal light pole. Staff remotely control the drone equipped with the height-adjusting bracket to park on the parking platform, and then operate the rotating device to rotate the drone's direction to monitor and provide real-time feedback on the areas that need to be monitored.
