Abstract

To address issues wherein tractors easily cross boundaries during soil preparation, a cross-boundary model for front, side and any arbitrary boundary was proposed. Based on BeiDou navigation satellite system (BDS), using John Deere Model 1204 tractor as the hardware platform and LabVIEW2018 as the software development platform, a hierarchical cross-boundary warning system of soil preparation was developed, and field tests under different boundary conditions were carried out. The test results show that the cross-boundary warning system for soil preparation proposed in this study had good judging and warning capacities for front, side and any arbitrary boundaries, with the tractor showing no cross-boundary behaviour during operation, suggesting the proposed system is stable and viable for application.

针对拖拉机整地作业过程中容易出现越界的问题，本文首先构建了车前、车侧和任意边界的越界预警模型，并基于北斗定位系统，以LabVIEW2018为开发平台，设计了一种具有越界预判功能的分级越界预警系统，最后以约翰迪尔1204型拖拉机为试验平台，悬挂旋耕机进行实地试验。试验结果表明，本文设计的越界预警系统对于车前、车侧和任意边界都有较好的判别和预警能力，拖拉机均未越界，分级越界预警系统运行整体较为稳定，系统可靠性较高，适用性较强
