Achievement method of multi-antenna unmanned aerial vehicle system

Abstract

The invention discloses an achievement method of a multi-antenna unmanned aerial vehicle system. The multi-antenna unmanned aerial vehicle system is characterized by comprising a remote control terminal, an unmanned aerial vehicle terminal and a mobile communication network, wherein the unmanned aerial vehicle terminal comprises a processor, a 3G / 4G communication module, a WIFI communication module and a Bluetooth communication module. By arranging the 3G / 4G communication module, the WIFI communication module and the Bluetooth communication module and setting the selection priority of communication modes, the problem that an unmanned aerial vehicle is simple in communication mode in the prior art is overcome, connection of the unmanned aerial vehicle and the remote control terminal in multiple communication modes is achieved, the communication modes can be freely switched at different distances and in different environments, and the communication stability and reliability of the unmanned aerial vehicle terminal and the remote control terminal are effectively guaranteed. The achievement method can be widely applied to various unmanned aerial vehicle systems.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to an unmanned aerial vehicle communication system. Background technique [0002] Unmanned aircraft, referred to as "drone" for short, and "UAV" for English abbreviation, is an unmanned aircraft controlled by radio remote control equipment and its own program control device. Antennas play an important role in drone transceivers. Its performance, especially directivity and efficiency directly affect the communication distance and the safety of the transmitter. According to the flight characteristics of UAV, for the communication antenna without servo, its pattern should be omnidirectional on the horizontal plane. Due to the limitation of the UAV load, the airborne antenna should be small in size and light in weight, and the influence of the shape on the flight performance of the UAV should be considered at the same time. [0003] In the prior art, the UAV has a single communi...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the UAV has a single communication method. When one of the communication methods fails or the signal is weak, the UAV loses control and easily leads to crashes and other problems.
