Technical Field

[0001] The present invention belongs to the technical field of power grid tower acceptance, and specifically relates to an AR-assisted unmanned aerial vehicle tower acceptance device and a use method thereof. Background Art

[0002] The acceptance of power grid towers is an important part of power grid construction. Towers are often erected near complex terrains such as mountains and gullies. The traditional method uses manual inspection and acceptance work, which is time-consuming, difficult, and dangerous. Multi-rotor drones are a type of small unmanned aerial vehicle that has emerged in recent years. They can perform vertical take-off and landing, hover in the air, and are simple to operate and low-cost. With this advantage, multi-rotor drones have gradually been put into the acceptance of power grid towers. They are equipped with cameras and image transmission equipment to approach the towers, which improves work efficiency and reduces operational risks.

[0003] However, as more and more multi-rotor drones are put into actual tower acceptance work, higher requirements are put forward for their related performance. For example, the traditional camera mounting method is mostly servo gimbal mounting, which limits the moving angle and often leads to visual blind spots; and the gimbal has poor flexibility when moving around. Summary of the invention

[0004] In order to overcome the shortcomings of the above-mentioned prior art, the purpose of the present invention is to provide an AR-assisted UAV tower acceptance device and a method of use, which solves the problem that the traditional camera mounting method in the prior art is mostly servo gimbal mounting, the moving angle is limited, and visual blind spots often occur; and the gimbal has poor flexibility when moving and flying around.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions to achieve it: an AR-assisted UAV tower acceptance device, including a UAV body, a flexible camera device, AR glasses, and a ground station; the UAV body is connected to the flexible camera device, the UAV body is arranged on the landing gear, the UAV body is wirelessly connected to the AR glasses and the ground station, and an image and data transmission device and a flight control system are arranged in the middle of the UAV body, and the image and data transmission device are electrically connected to the flight control system.

[0006] Preferably, the flexible camera device is composed of a connecting mechanism, a flexible driving mechanism, and a camera. One end of the flexible driving mechanism is connected to the bottom of the drone body through the connecting mechanism, and the other end of the flexible driving mechanism is connected to the camera.

[0007] Preferably, the flight control system is composed of a posture sensor and a GPS positioning system, and the posture sensor and the GPS positioning system are electrically connected to the image and data transmission device.

[0008] Preferably, the flexible driving mechanism is a hose-type structure.

[0009] Preferably, the hose-type structure of the flexible driving mechanism is a layered mesh polymer.

[0010] Preferably, the high molecular polymer is any one of polysiloxane, polyurethane and polyacrylate.

[0011] Preferably, the hose-type structure has an air flow channel inside.

[0012] Preferably, the length of the flexible camera device cannot exceed the distance from the connecting mechanism to the landing gear.

[0013] Preferably, the UAV body is any one of a quad-rotor, a hexacopter or an octacopter.

[0014] The present invention also discloses a method for using an AR-assisted UAV tower acceptance device, which is specifically performed according to the following steps:

[0015] Step 1: The operator uses the ground station to send instructions to the image data transmission device, and then the flight control system controls the drone to approach the tower;

[0016] Step 2: The flexible camera device collects the image data of the tower and the flight position and posture of the drone body and transmits them to the flight control system, and then transmits them to the AR glasses and the ground station through the image data transmission device, and the operator initially receives the image data of the tower;

[0017] Step 3: The image data transmission device transmits the posture data of the AR glasses to the flexible camera device. At the same time, the flexible camera device collects the posture data of the AR glasses to make corresponding position and posture changes, and performs all-round image data collection.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] An AR-assisted unmanned aerial vehicle tower acceptance device. In the prior art, the traditional aerial photography acceptance method is difficult to operate manually, and the operability is poor. The camera is synchronized with AR glasses to improve the convenience of operation. The traditional camera mounting method is mostly a steering gear gimbal, and the rotation range driven by the steering gear is limited, and the flexibility is limited. The flexible camera device realizes full free bending, which improves the visual blind spot problem of the traditional gimbal; the operator uses AR glasses to obtain the tower image data, and the flexible camera device collects the position and posture data of the AR glasses to perform corresponding position and posture changes, adjusts the camera angle and synchronizes with the operator's head movement, thereby improving the operability of the drone when flying around the tower, and improving the efficiency of the acceptance of the power grid tower. The present invention improves the flexibility and visual blind spot problems of the drone in the acceptance of the power grid tower, improves the system work efficiency, and enhances the reliability of the acceptance work.

[0020] Furthermore, the drive of the flexible drive mechanism is different from the traditional drive method. The hose-type structure is an elastic high molecular polymer with a layered mesh structure and an air flow channel inside. The hose can be bent by injecting gas into different air flow channels and different air flow rates. It has all-round precise rotation capabilities, thereby controlling the angle of the camera to be synchronized with the operator's head movement.

[0021] Furthermore, the length of the flexible camera device cannot exceed the distance from the connecting mechanism to the landing gear. The length of the flexible camera device should not be too long, otherwise it will interfere with the landing gear when rotating in all directions, and it should also not interfere with the ground.

[0022] Furthermore, the UAV body is any one of a quad-rotor, a hexacopter or an octa-rotor form, so that the present invention can be applied to UAVs of various models. BRIEF DESCRIPTION OF THE DRAWINGS
