Problems solved by technology

In addition, after the UAV lands at the landing station, there can be other follow-up work, which requires precise positioning. However, when the existing UAV lands, although it is controlled by a control system, its positioning accuracy is at the centimeter level. The accuracy is poor, which will have an impact on the follow-up work of the UAV. If the battery cannot be replaced automatically, if the UAV equipment is working outdoors and the outdoor wind is strong, the four arms of the UAV will be damaged. Parts are controlled and positioned separately, and the control is difficult, so the UAV cannot land quickly, which will affect the process of battery replacement or other follow-up work

Abstract

The invention discloses a precise positioning and fixing device for assisting the landing of the drone, which solves the problem of poor positioning accuracy of the landing of the drone in the prior art. The work provides convenience, and the scheme is as follows: a precise positioning slot for assisting the landing of the drone, including a limit slot for limiting the arm of the drone, the limit slot includes a flat brace set at the bottom, a flat brace The side is connected with the landing surface, the landing surface is a flat or curved surface, and the landing surface and the flat support are set at an angle. After the support leg of the UAV arm contacts the landing surface, it falls onto the flat support along the landing surface to achieve precise positioning.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an accurate positioning and fixing device for assisting unmanned aerial vehicles to land. Background technique [0002] UAV is an unmanned aerial vehicle controlled by radio remote control equipment and its own program control device. The UAV system consists of an aircraft platform system, an information collection system and a ground control system. Due to its simple structure and easy control, multi-rotor UAVs have developed rapidly. From cable inspection to express delivery, from ecological environment monitoring to disaster relief supplies, multi-rotor UAVs have been widely used in more and more fields. Applications, more and more tasks can be undertaken. [0003] At this stage, the main factor limiting the further development of multi-rotor drones comes from its endurance. Most quadrotor or multi-rotor UAVs are powered by batteries, and their endurance is...
