Emergency communication and support system based on tethered unmanned aerial vehicle and method

Abstract

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.

Description

technical field [0001] The invention belongs to the field of emergency communication and emergency rescue, and relates to an emergency communication and support system and method based on a tethered unmanned aerial vehicle. It specifically relates to a power supply through a tethered cable to achieve rapid lift-off and continuous flight work. The airborne flight control system realizes functions such as automatic take-off and landing, attitude stability, air maneuvering, and wind-resistant flight. It can carry portable communication base stations. Launched into the air to set up a special network for emergency communications, an emergency communications support system that can carry high-definition cameras into the air to realize video command support. Background technique [0002] The occurrence of natural disasters, major accidents and other events is sudden, and it is necessary to quickly establish a sustainable wireless broadband emergency communication network with a ce...
