Communication device, floating platform, emergency system and use method thereof

The invention provides a communication device, a floating platform, an emergency system and a using method thereof. The communication device comprises a communication part, an angle adjusting assembly, a position obtaining assembly and a signal transmission assembly. The angle adjusting assembly is connected with the communication piece and electrically connected with the position obtaining assembly through the signal transmission assembly. The position acquisition assembly acquires actual azimuth information; the signal transmission assembly transmits the actual azimuth information to the angle adjusting assembly; and the angle adjusting assembly adjusts the angle of the communication piece according to the actual azimuth information and the target azimuth information. By adopting the above structure, the accurate azimuth information of the adaptive target area can be obtained through the position obtaining assembly, the angle of the communication piece can be adjusted through the signal transmission assembl
