基于A9和Android平台的无人驾驶拖拉机主控系统的设计与开发
A9 and the Android platform based on the master control system of unmanned tractor design and development
利用高新技术改造传统农业，减少人力资源的投入，提升农业的产量和质量，对于维护粮食安全具有重要意义。因而针对我国农业生产机械化、自动化水平低的不足，本文设计开发了无人驾驶拖拉机主控系统，有效的提高了农业机械的自动化水平。该系统采用了基于A9和Android平台与传统农业机械相结合，使拖拉机具备自定位和自行走能力。在作业过程中,通过RK2928平板中的核心模块CC1110和SIM900A与车前摄像机及角度检测传感器，电机控制器的连接，实现拖拉机的定位,准确判断自身的姿态，然后综合控制拖拉机的转向和速度，最终实现按照规划路径行驶的目的自动直线行走，从而真正达到无人驾驶的目的，生产具有自主知识产权的智能农业机械，对推进我国农机科技的进步具有重要意义。
To transform traditional agriculture, using high and new technology to reduce the investment of human resources, improve the yield and quality of agriculture, is of great significance for maintaining food security. And low level of mechanization and automation of agricultural production in China, this paper designed and developed an unmanned tractor main control system, effectively improve the automation level of the agricultural machinery. The system USES the A9 and the Android platform based on combined with traditional agricultural machinery, tractors with the positioning and has the ability to walk. In the process of operation, through the core modules CC1110 and SIM900A RK2928 flat with the front of the camera and Angle detection sensor, motor controller connection, realize the tractor positioning, accurate judgment's own attitude, and then integrated control tractor steering and speed, finally realizes the automatically according to the purpose of planning routes walk straight, so as to truly achieve the goal of unmanned, intelligent agricultural machinery production with independent intellectual property rights, to promote the progress of science and technology is of great significance of agricultural machinery in our country.
