Emergency broadcast system based on unmanned aerial vehicle relay communication

Abstract

The invention provides an emergency broadcast system based on unmanned aerial vehicle relay communication. The emergency broadcast system comprises a management platform, a transmitting adapter, a broadcast television transmitting device, an unmanned aerial vehicle, a terminal, a broadcast television receiving device and a receiving adapter, wherein the unmanned aerial vehicle comprises a broadcast television receiving module, a controller, a wireless network module, a broadcast television transmitting module and a flight and control subsystem. According to the emergency broadcast system basedon unmanned aerial vehicle relay communication, when a local ground wireless network and a local broadcast television are interrupted, emergency broadcast is carried out, emergency broadcast messagesare issued, closed-loop management of emergency broadcast is achieved, local network service is provided, the coverage area is large, stable broadcast is kept, and complete receiving can be achievedon the ground.

Description

technical field [0001] The invention relates to the technical field of emergency broadcasting, in particular to an emergency broadcasting system based on unmanned aerial vehicle relay communication. Background technique [0002] When emergencies such as typhoons and earthquakes occur, the local terrestrial wireless network will be interrupted, and the local radio and television transmission network will be interrupted, making it impossible for the public to obtain rescue information. Some systems install speakers on the UAV to make emergency broadcasts and release rescue news; the disadvantage is that the coverage is small, and the UAV cannot be heard from a long distance, and the UAV is flying around, so it cannot be heard completely on the ground. . Need an emergency broadcasting system, when the local terrestrial wireless network and local radio and television are interrupted, emergency broadcasting is performed, emergency broadcasting messages are released, closed-loop ...
