自动驾驶技术在农业机械中应用

Application of Automatic Driving Technology in Agricultural Machinery

利用北斗导航技术实现农机的自动、智能、精准驾驶,是我国现代农业信息化发展的重点方向。以北斗导航技术为基础,阐述了国内外农机自动驾驶系统研究现状,研究了北斗农机定位解算算法,提出一种新的PVT解算算法。利用该算法设计了系统的硬件,并进行了试验模拟小车测试试验。结果表明,在场地和天气一定的条件下,该方案的定位精度比较理想。

Use of Beidou navigation technology to achieve automatic,intelligent,and precise driving of agricultural machinery is a key direction for development of modern agricultural informatization in China.Based on Beidou navigation technology,research status of automatic driving system of agricultural machinery at home and abroad was expounded,positioning algorithm of Beidou navigation ma-chinery was studied,and a new PVT algorithm was put forward.Hardware of the system was designed using this algorithm,and experi-mental simulation car testing was conducted.Results showed that under certain conditions of site and weather,positioning accuracy of this scheme was relatively ideal.
