Embodiment Construction

[0018] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0019] The UAV obstacle avoidance and return radar system of the present invention includes a navigation signal receiving module, an obstacle detection module, a signal analysis module and a main control module. The navigation signal receiving module can receive satellite navigation signals and guide the UAV to return to a designated Location. The signal analysis module is used to analyze the detection signal.

[0020] The obstacle detection module includes a radar main probe, which is used to detect obstacles in the forward direction of the drone's flight; the radar main probe includes two levels of scanning areas, wherein the scope of the second scanning area is within It is always included in the range of the first scanning area. When there is an obstacle in the first-level scanning area, the main control module will reduce the flying spee...

Abstract

The invention discloses an unmanned aerial vehicle obstacle avoidance and return flight radar system, which comprises a navigation signal receiving module, an obstacle detection module, a signal analysis module and a main control module. The navigation signal receiving module is used for receiving a navigation signal and guiding an unmanned aerial vehicle to return to a specified position; the signal analysis module is used for analyzing the detection signal; the obstacle detection module comprises a radar main probe, and the radar main probe is used for detecting obstacles in the positive flight direction of the unmanned aerial vehicle; in the mobile searching process, the radar main probe continuously scans the front, judges whether an obstacle exists in a secondary scanning area of the current position, and continuously moves if the obstacle exists; and if the obstacle does not exist, the unmanned aerial vehicle moves forwards at the current position and continues to move forwards. The search range of the unmanned aerial vehicle is gradually increased, grid type search can be realized, more repeated paths are reduced, the search time is shortened, and a proper obstacle avoidance route can be quickly found.

Description

technical field [0001] The invention relates to the technical field of drone control, in particular to an obstacle avoidance and return radar system for drones. Background technique [0002] With its compact and flexible body, UAVs are widely used in various inspections and monitoring, aerial photography and aerial broadcasting operations. The traditional UAV flight control is remote control through the ground control terminal. Once the remote control signal is interrupted, there will be problems in the flight of the UAV. In order to solve this problem, the prior art uses GPS signals to navigate the UAV to realize the autonomous flight of the UAV. However, the actual flight environment is complex, and drones are highly dangerous when flying autonomously. Contents of the invention [0003] The technical problem to be solved by the present invention is to solve the above-mentioned deficiencies in the prior art, and provide a UAV obstacle avoidance and return radar system. ...
