Abstract: The invention provides a communication system and a communication method. The communication system includes a wireless communication apparatus, a control center apparatus, and an unmanned aerial vehicle. The control center apparatus controls the unmanned aerial vehicle to fly within a first range, so that the unmanned aerial vehicle searches for the wireless communication apparatus within the first range. When the unmanned aerial vehicle finds the wireless communication apparatus within the first range, the control center apparatus controls the unmanned aerial vehicle to fly within a second range. The second range is equal to or less than a communicable range of the wireless communication apparatus. The unmanned aerial vehicle continuously receives a physiological information signal with physiological information transmitted by the wireless communication apparatus. The unmanned aerial vehicle transmits the physiological information signal back to the control center apparatus.

Abstract: A multihull module is provided. The multihull module includes multiple power floats, an actuation interface controller, and a vehicle controller. The power floats are disposed on a vehicle. The actuation interface controller is coupled to the power floats, and is configured to control the power floats. The vehicle controller is coupled to the actuation interface controller, and is configured to provide a control signal to the actuation interface controller. The actuation interface controller controls the power floats according to the control signal.

Abstract: A ship docking system and a ship docking method are provided. The ship docking system includes a computing device, an unmanned aerial vehicle communicating wirelessly with the computing device and pre-docked on a charging platform, and a display device communicating wirelessly with the computing device. When the computing device determines that the ship is performing a port entry operation, the computing device controls the unmanned aerial vehicle to move to a preset height above the ship and to obtain a panoramic image of the ship. The unmanned aerial vehicle transmits the panoramic image to the computing device, so that the computing device analyzes the panoramic image to perform a collision prediction of the ship, and transmits a collision prediction result to the display device.

Abstract: A power wheel including a positioning device, a wireless communication module, and a controller is provided, where the controller is configured to operate in an active mode or a passive mode. When operating in the passive mode, the controller is configured to: acquire route information and moving information from the power wheel operating in the active mode by the wireless communication module, and acquire relative position information with the other power wheels by the positioning device; and determine a rotation strategy of the power wheel according to the route information, the moving information and the relative position information. When operating in the active mode, the controller is configured to: acquire the route information, and transmit the route information to the other power wheels; and determine the rotation strategy of the power wheel according to the route information. In addition, a cooperative carrying method of the power wheel is also provided.
