Problems solved by technology

Moreover, the unstable network signal transmission in remote areas will also affect the reliable use of the system
At the same time, the Wi-Fi communication system also has communication distance limitations
[0005] In summary, the current communication link between the Android ground station and the quadrotor UAV has problems of insufficient reliability and limited distance

Abstract

The embodiment of the invention discloses a quadrotor unmanned aerial vehicle communication method and system based on Bluetooth and Wi-Fi, and relates to the field of unmanned aerial vehicle communication. The two data transmission measures of Bluetooth and Wi-Fi are used for forming an effective redundancy structure used for realizing the wireless communication between an Android ground station and an unmanned aerial vehicle; a remote control instruction of the Android ground station can be parallelly and fast received; the reliability and the real-time performance of the wireless communication between the Android ground station and a ground test and control terminal can be improved in an instruction code repeating and multi-time and two-path parallel sending mode; the communication distance is expanded in a wireless communication mode; the problem of communication distance limitation is avoided.

Description

Technical field [0001] The present invention relates to the field of drone communications, and more particularly to a four-cyclic drone communication method and system based on Bluetooth and Wi-Fi. Background technique [0002] In the contemporary society of informationization, with the wide use of microelectromechanical, microelectronics and micro-navigation, drone technology quickly became a research hotspot, and it has developed rapidly. Since the four-rotate drone is reversed by the adjacent rotor, there is no counter-torque, so it is not necessary to design the tail paddle to balance the rotor anti-torque, with a vertical property such as a vertical, hovering, and rapid changes in the posture, and ordinary unmanned Compared with the advantages of small size, good mobility, cost performance, there is a huge application value in military and civilian. [0003] The ground station is an important part of the drone system, which is responsible for controlling the aircraft and col...
