Research on Wireless Automatic Navigation and Positioning System of Seeder Based on Big Data Technology

为了提高播种机的定位导航效率及导航自动化水平,将大数据处理技术和无线传感网络技术引入到了导航系统的设计上,并通过定位算法对位置信息进行估计,实现了播种机的自动定位导航。模拟农田作业的环境,在700m×1000m的网格区域范围内布置了传感器节点,并利用仿真计算的方式对导航的精度进行了测试。测试结果表明:采用三边测量法,结合PID控制器可以有效提高定位精度,可对自动导航系统的设计提供较有价值的借鉴。

In order to improve the positioning and navigation efficiency of seeder and improve the level of navigation automation,it introduced big data processing technology and wireless sensor network technology into the design of navigation system,and used the positioning algorithm to estimate the position information to realize the automatic positioning and navigation of seeder.The sensor nodes are arranged in the grid area of 700m×1000m,and the navigation accuracy is tested by simulation calculation.The test results show that the trilateral measurement method combined with PID controller can effectively improve the positioning accuracy,which provides a valuable reference for the design of automatic navigation system.
