Unmanned aerial vehicle testing platform

Abstract

The invention relates to the technical field of unmanned aerial vehicles and discloses an unmanned aerial vehicle testing platform. The unmanned aerial vehicle testing platform comprises a flange plate, a rotating bearing, a base and a conductive slip ring. A mounting hole is formed in the flange plate and used for mounting an unmanned aerial vehicle; the flange plate is rotationally mounted on the base through the rotating bearing; the conductive slip ring comprises a rotor end and a stator end; and the rotor end is electrically connected with the unmanned aerial vehicle; and the stator end is connected with the base. Through the rotating of the rotating bearing, degree of freedom needed to test yawing movement is provided for the unmanned aerial vehicle; the unmanned aerial vehicle is inwire connection with a power supply and signal receiving device through the conductive slip ring so that the unmanned aerial vehicle gets rid of limitation of limited battery capacity and overcomes defects that the wireless transmission speed is low and the unmanned aerial vehicle is easy to be interfered; and therefore, the unmanned aerial vehicle can efficiently and accurately transmit and receive information; and the rotor end and the stator end of the conductive slip ring can relatively rotate to avoid bending distortion of a transmission lead. According to the unmanned aerial vehicle testing platform, an efficient and reliable testing platform is provided for the yawing movement of the unmanned aerial vehicle; and moreover, the structure is simple, the operation is convenient, and the practicability is very high.

AI Technical Summary

Problems solved by technology

At present, the existing unmanned test requires a relatively large site. When the drone is running, it is difficult to accurately observe the attitude and motion performance of the drone itself; the drone and the ground station are generally connected wirelessly, which is limited by wireless transmission signal transmission. The status quo of slow speed and susceptible to interference makes it difficult to obtain and observe detailed flight data of UAVs in real time, resulting in greatly reduced test efficiency

Most of the existing UAV test platforms are relatively heavy and inconvenient for testers to operate, and there is a certain size limit for the UAV under test, which lacks versatility

In addition, current drones generally use their own dedicated lithium batteries for power supply. The flight time is limited by the power of lithium batteries. Long-term tests require multiple battery replacements, which affects test efficiency. Moreover, large-capacity lithium batteries are expensive, so prepare multiple lithium batteries. The battery will increase a lot of testing costs
