Design And Development Of Supervision System For Mobile Phone Of Multi-rotor Drones

In this paper,the supervision system of drones based on i OS is designed according to the self-developed flight control system of drones.The system is divided into two mobile apps based on actual needs: the parameter adjustment software and the management and control software.They are respectively used to set flight parameters of drones,calibrate remote control,check parameters of the drone and control the flight of drones.The system was developed using the Xcode software platform,and Objective-C language was used to achieve all the functional requirements.Compared with the traditional PC-based drone monitoring system,The design has the advantages of stable operation,comprehensive functions,simple operation,simple interface and wide applicability.The main work of this article is as follows.(1)According to the requirement analysis of the system,the overall structure have been designed.Each module of the hardware platform is introduced.The interface design and function module design of supervision system are described.The system communication protocol is designed to realize data interaction.The algorithm of track planning in irregular area and the algorithm of track planning after adding obstacles in operation area are studied and designed.(2)In terms of function module design of the parameter adjustment software,account login,password management,language switching,etc are realized.BLE-bluetooth communication is designed and realized.Setting and obtaining parameters of drone are Feasible.The calibration of remote control is designed and realized.(3)In the management and control software,Socket communication,HTTP communication and BLE-bluetooth communication are designed and realized.Loading and display of Gaud map are realized and related map operations are completed.Picking the boundary point of track scheme is realized and track scheme generation is designed and realized.Uploading and saving track solutions to the server are realized.The saved track schemes can be achieved from the server and be reused.The assignments of track schemes are designed and realized.One key take-off,landing and other control of drone are realized.Finally,the outdoor joint flight test of the drone supervision system and the multi-rotor drone have been done.The drone worked normally and the communication was normal during the test,which verifies the feasibility and stability of each functional module in the design and meets the functional requirements.The system is stable operation.The desired results have been achieved.
