A9 and the Android platform based on the master control system of unmanned tractor design and development
利用高新技術改造傳統農業，減少人力資源的投入，提升農業的產量和質量，對於維護糧食安全具有重要意義。因而針對我國農業生產機械化、自動化水平低的不足，本文設計開發了無人駕駛拖拉機主控系統，有效的提高了農業機械的自動化水平。該系統采用了基於A9和Android平臺與傳統農業機械相結合，使拖拉機具備自定位和自行走能力。在作業過程中,通過RK2928平板中的核心模塊CC1110和SIM900A與車前攝像機及角度檢測傳感器，電機控制器的連接，實現拖拉機的定位,準確判斷自身的姿態，然後綜合控制拖拉機的轉向和速度，最終實現按照規劃路徑行駛的目的自動直線行走，從而真正達到無人駕駛的目的，生產具有自主知識產權的智能農業機械，對推進我國農機科技的進步具有重要意義。
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.
