Abstract

The invention relates to a drone control signaling and a data transmitting method based on a mobile network. The drone comprises: a broadband data transmitting system applicable to high-definition video transmission of the drone, a control signaling transmitting system for receiving drone state data and sending drone control commands, a drone cloud service system for forwarding data, and a groundstation system for receiving video and remotely controlling the drone. According to the drone control signaling and data transmitting method based on a mobile network, a 4G-LTE network card is mountedon an airborne computer of the drone end, the telemetry data and the aerial video data in the flight process of the drone are compressed and encoded by the airborne computer, and transmitted via the4G mobile network. The activity range of the drone is no longer limited by the data link transmission distance by connecting the drone into the mobile internet, and the application field of the dronecan be greatly expanded.

Description

technical field [0001] The invention belongs to the field of unmanned aerial vehicles, and relates to wireless data transmission, in particular to a design method for remote measurement data transmission, image data transmission and remote control system of unmanned aerial vehicle based on 4G mobile network. Background technique [0002] UAV is an unmanned aircraft controlled by radio remote control equipment and its own program control device. According to different aerodynamic principles, UAV has many different forms such as fixed-wing glider, helicopter, and multi-rotor aircraft. . At present, drones are widely used in many fields such as agricultural plant protection, power inspection, aerial photography, surveying and mapping. At the same time, the communication link, as the link between the ground station and the UAV, is an important part of the UAV. Usually, in order to be able to monitor the flight status of the UAV in the air in real time on the ground side, it is...
