针对丘陵山地果园作业环境复杂,导致山地果园除草机自主作业精度低、稳定性差等问题,本研究开发了一套基于北斗导航的山地果园除草机控制系统.该系统结合多传感器数据融合与遥控打点技术精确标记果园中除草作业的范围边界及障碍物位置,利用北斗差分定位技术来精确定位除草机的工作位置,实现精准定位.采用A-star算法规划除草机的最佳作业路径,确保山地果园除草机自主完成除草作业任务.该除草机采用了履带式仿形底盘作为其行走机构,由增程式油电混合动力系统提供充足动力,保证了优良的通过性和和作业持久性.田间测试结果显示,在行进速度为0~6 km/h或作业效率为2~4 mu/h,除草机器人定位精度≤96 mm、静态基线测量水平精度≤65 mm、垂直精度≤53 mm,最大爬坡度为30°.表明本研究提出的控制系统能够满足山地果园除草机自主作业精度要求.
Design and Experimental Study of Weed Control System for Mountain Fruit Orchards Based on Beidou Navigation
In response to the complex operating environment in hilly and mountainous orchards,which leads to low autonomy and stability in orchard weed removal machines,this study developed a control system for orchard weed removal machines based on Beidou navigation.The system combines multi-sensor data fusion and remote control marking technology to precisely mark the boundaries and obstacles of weed removal operations in orchards.It uses Beidou differential positioning technology to accurately determine the position of the weed removal machine,achieving precise positioning.The weed removal machine uses a tracked conforming chassis as its walking mechanism and is powered by an extended range hybrid power system to ensure excellent mobility and long-term operation.The field test results show that the weed removal robot has a positioning accuracy of ≤96 mm,a static baseline measurement horizontal accuracy of ≤65 mm,and a vertical accuracy of≤53 mm at a travel speed of0~6 km/h or an operation efficiency of2~4 acres/hour.The maximum climbing angle is 30°.These results indicate that the control system proposed in this study can meet the precision requirements for autonomous oper-ation of orchard weed removal machines.
