AI Technical Summary

Problems solved by technology

The digital transmission rate of the second-generation system is only 9.6Kbps, and the transmission speed will drop significantly under mobile conditions
However, due to the characteristics of variable time delay, variable bandwidth, and unpredictable connectivity when using cellular mobile communication for data communication, it cannot fully meet the requirements for real-time control of aircraft.
For example, when GPRS (General Packet Radio Service) has a typical bandwidth of 40kb / s, the data transmission has a delay of 200ms. If the speed of the aircraft is 100km / h, the aircraft has already flown 5.6m when the control command arrives. The delay will lead to serious flight accidents, and because there is no feedback information, the aircraft cannot actually fly beyond the visual range

Description

technical field [0001] The invention relates to a control system of an unmanned aerial vehicle, in particular to a control system of an unmanned aerial vehicle based on cellular mobile communication. Background technique [0002] In addition to military uses, unmanned aerial vehicles are also widely used in civilian applications, such as collecting atmospheric samples, mapping, resource surveys, disaster investigations, and anti-drug reconnaissance. Unmanned aerial vehicles include unmanned aircraft, helicopters and airships, etc., and are generally composed of power devices and power systems, automatic control devices and actuators, wireless communication and navigation systems, mission systems and remote control systems, and most of them also require ground control. system. Except for large unmanned aircraft using gas turbine engines, the flying speed of unmanned aerial vehicles is generally below 400km / h, the flying speed of helicopters is not more than 200km / h, and the ...
