The invention relates to an emergency communication and
support system based on a tethered unmanned aerial vehicle and a method. The
system comprises a flying platform subsystem, a ground control subsystem, a photoelectricity composite cable and a communication terminal. The flying platform subsystem comprises the unmanned aerial vehicle. A communications
base station, a
base station antenna and a video capturing device are arranged on the unmanned aerial vehicle. The ground control subsystem is connected with the flying platform subsystem through the photoelectricity composite cable, and controls and communicates with the flying platform subsystem through the photoelectricity composite cable. The photoelectricity composite cable transmits ground power to the flying platform subsystem, and realizes space data two-way
optical fiber transmission. The communication terminal establishes communication connection with the ground control subsystem and the flying platform subsystem. The
system and the method, which are provided by the invention, have the technical advantages of long air time,
signal blind spot prevention and real-time air video capturing, and can be used for low-cost cluster communication and video
support system solutions in the fields of
public security, terrorism countering, high-rise building
fire protection and the like.
