Large and medium-sized unmanned aerial vehicle communication relay system

Abstract

The invention discloses a large and medium-sized unmanned aerial vehicle communication relay system. The system comprises an airborne 4G broadband communication base station, a line-of-sight airbornedata terminal, a satellite communication airborne data terminal, an airborne switch, an airborne protocol module, a high-definition video encoder and a high-definition photoelectric load which are arranged on an unmanned aerial vehicle, and a satellite communication ground data terminal, a ground command control station and a ground portable terminal, wherein the satellite communication ground data terminal is in two-way signal connection with the ground command control station; the airborne 4G broadband communication base station and the ground portable terminal or other flying platforms arein video and voice communication connection and are in two-way signal connection with the airborne switch; the airborne switch is in two-way signal connection with the satellite communication airbornedata terminal through the line-of-sight airborne data terminal; and the high-definition photoelectric load is in one-way signal connection with the airborne switch through the high-definition video encoder. According to the system, a 4G relay function of the unmanned aerial vehicle within an oversight range can be realized, the wide area network access is achieved through a satellite, and the relay communication function of a ground unit or the other flying platforms is achieved.

Description

Technical field [0001] The invention belongs to the field of drone communication, and relates to a communication relay system for large and medium-sized drones. Background technique [0002] The UAV system is divided into an air part and a ground part. The air part is the UAV platform. The ground part contains one or more ground stations. The operator is located in the ground station to control the UAV flight and perform tasks. [0003] The UAV data link is divided into line-of-sight data link and satellite data link. The range of the line-of-sight data link is limited by the line-of-sight range of the UAV and the ground station. Generally, the farthest range is 250km~300km. At present, the use of Satcom data link is the main technical means to realize the UAV system beyond the visual range measurement and control and information transmission. The satellite data link uses geosynchronous orbiting communication satellites for relay transmission, and is not limited by the line-of-sig...
