The Design And Implementation Of Terminal Control System For Small Unmanned Aerial Vehicle Based On Android

Along with the development of small unmanned aerial vehicles (UAVs) application technology, the flight control technology is also increasingly become a hot research at home and abroad. The ground-based control software is one of the most important part of the whole UAV system. The ground-based control system monitors the status of aircraft flight state and state of airborne equipment real-time. It guarantees the reliability and effectiveness of the aircraft mission.The traditional ground-based control system for small aircraft runs at the desktop system. With poor portability and poor anti-interference problem, they are not conducive to control the craft and acquire data. With the mature of mobile Internet technology, the smart mobile terminals will take the place of the traditional control terminal as an aircraft control system terminal. Smart mobile terminal is small in size, easy to carry, while strengthen the operating flexibility and increase the scope of control. Smart mobile terminal can receive more types of data and information with so many sensor devices the traditional control system can’t match. Among the mobile terminal, the Android platform is one of the best. So this paper develop the mobile terminal control system with Android language. The main work of this paper is as follows:1) Introduces the concept of UAV and ground-based control system, and the current situation at home and abroad. Then this paper illustrates the goal of this top research and the main work content.2) Analyzes the Android development technology. Focus to understand the Android interface design technology and the socket communication technology based on TCP/IP. 3) Based on the functional requirements and performance requirements of the terminal control system, carries out the detailed design for all the functions modules of the terminal control system. Then briefly illustrates the working process of the control system.4)According to the main function requirements, use the relative technology to develop the user interface module, data communication module and the flight control module, and realize the function of each module.5)Research the ant colony algorithm (ACO) applied to path planning problem. Builds a two-dimensional geographical environment model with grid method and analyze the principle of ant colony algorithm; Improved ant colony algorithm to make it more adaptable to the grid environment and the characteristics of path planning; Make simulation experiment to verify its validity.
