AI Technical Summary
Existing drone relay communication devices have limited battery power, resulting in limited flight time and making it difficult to ensure uninterrupted communication in the deployment area for extended periods.
A drone relay communication device was designed, comprising a drone body, a shell, a relay device body, a motor, a winding and conveying unit, a counterweight, an airbag, and an electric gripper. The motor drives the winding tube to unwind the conveyor belt, which in turn lowers the counterweight and airbag to the ground. The airbag is then compressed to release helium gas, causing it to expand. By utilizing the fact that helium has a lower density than air, the drone and the relay device can be levitated in the air, enabling long-term aerial communication.
This enabled the long-term aerial deployment of drone relay communication devices, ensuring uninterrupted communication in the deployment area and solving the problem of insufficient loiter time caused by limited power.
