Design Of Ground Control System For Small Quadrotor UAV Based On Android

In recent years,due to the characteristics of small size,good mobility,relatively simple structure and high cost performance,quadrotor unmanned aerial vehicle(UAV) has the great value in military and civilian application, and become one of the most popular research projects. As the important supporting systemof quadrotor UAV,ground control systemis also developing rapidly.The traditional ground control system is large, difficult to carry and has short battery life.This paper proposes a new kind of ground control system for quadrotor UAV based on Android.At the same time this paper designs a new kind of communication system of small quadrotor UAV based on bluetooth and digital radio.The ground control system based on Android in this paper also designs its own tracking control circuit,which is different from traditional ground control system.Firstly,this paper investigats the characteristics and development of quadrotor UAV,and set up the quadrotor UAV platform.This paper also propose the technical scheme for implementation of the system,and detailed analysis the demand of ground control system.Secondly,thispaper investigats and design the communication system consisted of bluetooth,singlechip,and digital radio.Software and hardware scheme are designed and realized in this paper,which making the design costs minimum power at the same time.This paper also expounds the important technical details in the design process.Thirdly, according to the design requirements of the ground control system, this paper respectively designs the modules of bluetooth, data transmission, instrument panel, remote control, GPS, navigation map, calibration, logging and so on. Moreover, the tracking control circuit is implemented in the navigation map module, which reduces the operation load of airborne platform effectively.Finally, a technical and personal test and validation scheme are carried on communication system and ground control system. Test results show that the key problems are solved efficaciously and the design method is scientific, correct and doable. The function and performance index of each module can well meet the basic requirements of ground control system for quadrotor UAV.
