Software Design Of Quadrotor Unmanned Aerial Vehicle And Its Remote Monitoring Platform

The quadrotor unmanned aerial vehicle (UAV) has become a current research focus for its great features like simple structure, good maneuverability,low manufacturing precision, good stability, less gyroscopic effect and good control operational flexibility. Due to the multivariate, coupled and underactuated dynamic characteristics, the control model and parameter settings has always been a key point in the research of quadrotor UAV. This paper aims to design a communication system to communicate wirelessly between quadrotor UAV and remote controller in order to achieve real-time remote monitoring.Aircraft and remote operating platform’s MCU are STM32series based on ARM Cortex-M.By analysising Strapdown Inertial Navigation model, quaternion, classical PID motor control models,the author edited releavant source code to make the quadrotor UAV work successfully,developed a wireless communication protocol between aircraft and ground station to achieve wireless real-time communication between them.The monitoring platform realized real-time monitoring, data archiving, parameter tuning and other functions by design related monitoring interface.By building μC/OSII operating system on it,the remote controller maintain a good scalability to implement new features in subsequent development.The simulation test shows that the design of four-rotor aircraft and monitoring platform is reliable.The code for algorithm development is concise and able to provide technical support for similar research and development.
