Description

Technical Field

[0001] The invention belongs to the technical field of unmanned aerial vehicles, and in particular relates to a quick wearable unmanned aerial vehicle lost connection positioning device. Background Art

[0002] Unmanned aircraft, referred to as "drones", are unmanned aircraft controlled by radio remote control equipment and self-contained program control devices. With excellent maneuverability and powerful mapping and aerial photography functions, they have been widely used in water conservancy, forestry, agriculture, plant protection and other fields. However, when performing field mapping and aerial photography tasks, drones often lose contact, crash and other accidents due to factors such as meteorological conditions, magnetic field interference, improper human operation, and internal machine failures. At the same time, the field environment in which drones work is complex and diverse, with dense forests or gullies, and limited vision. Once a drone crashes, the battery falls off, or the signal is interfered with, it is difficult to determine the position of the aircraft simply by the wireless positioning device of the drone and the remote control under the conditions of vegetation or terrain obstruction, resulting in delays in mapping and aerial photography tasks, and even property losses. Therefore, a device suitable for different brands of aircraft, which can be quickly equipped and disassembled, and has multiple functions such as visual-audio auxiliary positioning and crash protection, can quickly locate the position of the lost drone, which is of great significance for ensuring the progress of mapping tasks and saving manpower, material and financial resources.

[0003] At present, there are no unified standards and methods for unmanned aerial vehicle (UAV) loss of contact positioning and protection devices in China and abroad. There are two main types of existing positioning devices: ① GPS positioning devices. Most of the UAV flight controls on the market currently use a combination of GPS satellite navigation systems and inertial navigation systems. They rely on the manufacturer's own accelerometers, gyroscopes, electronic compasses, magnetometers and other sensor components. According to the pre-set synchronization time or the quality of the ground control station, the GPS module is used to accurately locate the UAV and display the positioning results on an electronic map. Although this type of device has high positioning accuracy, it is more dependent on the strength of the signal in the mission area. When affected by weather, terrain and vegetation, the positioning accuracy is low. In addition, when the UAV falls, it is often accompanied by a battery failure or detachment. The UAV cannot be turned on normally, and thus cannot be accurately positioned. ② Directional antenna device. The directional antenna automatic tracking control system calculates the real-time position of the directional antenna gimbal. According to the real-time position information of the UAV and the real-time position of the directional antenna gimbal, the target angle of the yaw motor axis and the target angle of the pitch motor axis of the directional antenna are calculated. Then, the drive motor is controlled to rotate, and the current angle of the yaw motor axis and the current angle of the pitch motor axis of the directional antenna are adjusted to the target angle of the yaw motor axis and the target angle of the pitch motor axis of the directional antenna, respectively, so that the directional antenna is aimed at the UAV, thereby realizing the communication transmission between the directional antenna gimbal and the UAV.

[0004] In summary, the existing field measurement of soil wind erosion mainly faces two problems: ① The problem of positioning accuracy and R&D cost. Most positioning devices are directly developed by manufacturers, with high development and production costs, and some devices have single functions. Due to the harsh outdoor climate environment, many factors not controlled by humans, large temporal and spatial variability, and complex aircraft crash sites, the fuselage, gimbal and other parts will be seriously damaged when the aircraft crashes, and there is a situation where the power supply cannot be normal. The built-in positioning module cannot obtain accurate location data, and high maintenance costs will be incurred after finding it. ② The universality of positioning devices for various brands or versions of aircraft. Most existing devices need to be integrated into the aircraft firmware. At present, there are hundreds of aircraft brands on the market, and the lost contact positioning devices are also mixed. The installation and operation methods are complicated and not conducive to promotion. There is no set of devices that can effectively adapt to different brands and models, and be convenient and fast in use and equipment.

[0005] Therefore, a quick wearable unmanned aerial vehicle lost connection positioning device is proposed to solve the deficiencies in the prior art. Summary of the invention
