Unmanned aerial vehicle image and video transmission and distribution system and method based on 4G network

Abstract

The invention relates to an unmanned aerial vehicle image and video transmission and distribution system and method based on a 4G network. The system comprises an unmanned aerial vehicle, corresponding flight control hardware, and a Raspberry Pi board, wherein the Raspberry Pi board is connected with the flight control hardware of the unmanned aerial vehicle, and obtains the flight control information of the unmanned aerial vehicle. The system comprises: a cloud server for receiving the unmanned aerial vehicle flight control information transmitted based on the 4G network, wherein a pluralityof specified mobile phones access the server to download the flight control information, and the mobile phones which use a 4G network and are provided with ground station apps developed autonomously,wherein the unmanned aerial vehicle ground stations can receive return signals from different unmanned aerial vehicles at the same time and control the multiple unmanned aerial vehicles at the same time. According to the unmanned aerial vehicle image and video transmission and distribution system and method based on the 4G network, unmanned aerial vehicle flight control information is sent to a cloud server by using a mavlink protocol, video and flight control information can be received by a multi-mobile phone end ground station app, and the limitation that only one device can receive unmanned aerial vehicle video and flight control information in a traditional method is broken through.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, specifically a 4G network-based unmanned aerial vehicle image and video transmission and distribution system and method. Background technique [0002] UAVs are now more and more widely used in aerial photography, reconnaissance, public security / fire protection / traffic / emergency rescue, customs border defense / marine surveillance inspection, real-time broadcast / on-site monitoring, power line inspection / pipeline inspection line, plant protection, etc. widely used. At present, the UAV flight control information transmission method is mainly based on WIFI UAV flight control transmission technology, and its information transmission speed is reliable, but the ground station at the receiving end must keep a relatively short distance from the UAV, and the receiving end can only be one Multi-terminal reception cannot be achieved without a UAV controller or mobile phone. [0003] UAVs are...
