Mobile nest for automatically replacing battery of small unmanned aerial vehicle and parking apron thereof

Abstract

The invention discloses a mobile nest for automatically replacing a battery of a small unmanned aerial vehicle. The mobile nest comprises a mobile nest body and a control unit. The movable nest body comprises a bottom plate, a bottom plate frame, a movable top cover, a parking apron arranged on the bottom plate, a three-dimensional module unit and a mechanical clamping jaw. A charging bin is arranged in the parking apron. The control unit comprises an industrial personal computer, a control module and a plurality of servo controllers, which are connected in sequence, the industrial personal computer sends instructions to the control module, and the control module executes the instructions of the industrial personal computer to control the servo controllers, so that an unmanned aerial vehicle is controlled to accurately land and be fixed on the parking apron; and the three-dimensional module unit moves, the mechanical clamping jaw moves the unmanned aerial vehicle to a fixed landing position, the battery is taken and placed between the unmanned aerial vehicle and the charging bin, and battery information in the charging bin is monitored. A platform capable of accurately landing andfastening the unmanned aerial vehicle is provided, a battery of the unmanned aerial vehicle can be continuously charged, and the mobile nest is an unattended and movable unmanned aerial vehicle intelligent parking apron system in the true sense.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a mobile nest for automatic battery replacement of a small unmanned aerial vehicle and its apron. Background technique [0002] At present, drones have been widely used in many fields such as power grid inspection, surveying and mapping, cruise, environmental monitoring, express delivery, etc. The precise landing and endurance of drones are important factors that affect the application and development of drones in various industries at this stage. factor. However, limited by the drone's own structure, weight and battery technology, drones can fly intelligently for half an hour at most, and the range is short, which seriously affects the ability of drones to perform tasks in various industries. Therefore, there have been various aprons that can charge drones for battery life and precise landing. The existing positioning technology of UAV landing position is main...

AI Technical Summary

Problems solved by technology

[0004] (1) Although the parking box equipment is equipped with a casing, which solves the problem that the drone is easily disturbed by the environment when it is parked and charged, the casing of the parking box equipment is closed around and has an opening on the top, which greatly limits the unmanned Due to the space limitation of this structure during the descent of the UAV, the airflow recoils, the UAV is not easy to stabilize, and the difficulty of UAV landing is increased;

[0005] (2) The UAV must land in the rectangular area surrounded by the four positioning sliders set on the apron. At the same time, use the four positioning sliders to push the UAV to the designated position. The start switch locks the support legs of the drone. On the one hand, setting the slider in the parking area will affect the smooth landing of the drone. On the other hand, the stability of the drone when it is stopped cannot be guaranteed during the process of being pushed by the positioning slider. , and the fastening effect is poor;

[0006] (3) The charging cabinet is set at the rear of the robotic arm. After the robotic arm picks up the drone battery, it needs to rotate to put the removed battery into the charging slot of the charging cabinet, which increases the pick-and-place stroke of the robotic arm. and difficulty, and the mechanical arm is positioned by the lifting rod, and the positioning accuracy is very low
