When the second charging terminal 28 approaches the first fixing seat 64, the second charging terminal 28 abuts against the first baffle 70 through the guiding of the second positioning groove 60, and then the second charging terminal 28 pushes the first baffle 70 away from the body 16, and extends into the first fixing seat 64 through the first opening 68 to be connected with the first charging terminal 22.

In some embodiments, the charging operation may be triggered by positioning the movable platform 12 at a target location of the base station 14.

Specifically, the base station 14 may include a positioning device 30, the positioning device 30 including a moving member 34 and a driving mechanism 36, the driving mechanism 36 being mechanically coupled to the moving member 34. The driving mechanism 36 can be used to drive the moving member 34 to move, thereby aligning the movable platform 12 and releasing the movable platform 12. After the movable platform 12 is located on the base station 14, the driving mechanism 36 can control the moving member 34 to close to perform the positioning of the movable platform 12 on the base station 14, so that the movable platform 12 is located at the target position of the base station 14. At the target position, the movable platform 12 typically triggers a position switch to generate a position detection signal, which indicates that the movable platform 12 is at the target position and the first and

second charging terminals

22 and 28 are connected, and the base station 14 can charge the movable platform 12.

If the moving member 34 positions the movable platform 12, the base station 14 finally does not receive the in-position detection signal, which indicates that the movable platform 12 is not positioned to the target position, at this time, the driving mechanism 36 may control the moving member 34 to release the movable platform 12, and then control the moving member 34 to close again, and position the movable platform 12 to the target position again. Until the base station 14 receives the presence detection signal, indicating that the mobile platform 12 is at the target location of the base station 14, the base station 14 charges the mobile platform 12.

The power line realizes the wired communication between the base station 14 and the movable platform 12, ensures the reliability of the communication, optimizes the connection scheme of the communication and the charging of the base station 14 and the movable platform 12 to the maximum extent, and reduces the signal lines of the communication by using the power line communication.

In one embodiment, the movable platform 12 is a drone and the base station 14 is a drone airport. The unmanned aerial vehicle mainly comprises a charging control module, an aircraft control module and a battery module. The unmanned aerial vehicle airport mainly comprises a charging control module, an airport control module and an AC-DC power supply module. After the drone is moved to the target location by the moving member 34 (e.g., a pushrod), the airport control module turns on the power module to supply power to the communication module without the airplane, and the airport and the drone establish wired communication through the power carrier signal of the charging terminal. When the communication is successfully established, the unmanned aerial vehicle turns on a charging switch, and the AC-DC power module is adjusted to input through communication with the airport control module, so that the charging function of the unmanned aerial vehicle is completed.

In some embodiments, the mover 34 is controlled to position the movable platform 12 on the base station 14 such that the movable platform 12 is at the target position of the base station 14; when the movable platform 12 fails to be aligned to the target position of the base station 14, the moving member 34 is controlled to repeatedly align the movable platform 12, including:

controlling the moving member 34 to close to clamp the movable platform 12 at the target position of the base station 14, controlling the moving member 34 to release the movable platform 12 when the movable platform 12 is not aligned to the target position of the base station 14, and controlling the moving member 34 to close again, and repeating the process to realize that the movable platform 12 is aligned to the target position of the base station 14. In this way, the movable platform 12 can be repositioned by closing the moving member 34, and the movable platform 12 can be repositioned by releasing the moving member 34.

Specifically, the moving member 34 may be plural (two or more). When closed, the plurality of moving members 34 move toward the movable platform 12 and push the movable platform 12 to move toward the target position, so that the movable platform 12 can be clamped at the target position of the base station 14.

When the position detection signal is not received, it indicates that the movable platform 12 has not been repositioned to the target position of the base station 14. At this point, the moving member 34 is controlled to release the movable platform 12, and the moving member 34 is controlled to close again, and the process is repeated to realize that the movable platform 12 is controlled to be aligned to the target position of the base station 14. Upon receiving the position detection signal, indicating that the movable platform 12 is positioned to the target location of the base station 14, the base station 14 may charge the movable platform 12.

To sum up, the embodiment of the present invention provides a movable platform system 100, which can at least realize the following technical effects: the base station 14 does not need a high-precision battery replacement mechanical structure for charging, so that the cost is saved, and the reliability is improved.
