基于GSM嵌入式物流监控的农业自主导航车辆设计

Design of Agricultural Autonomous Navigation Vehicle Based on GSM and Embedded Logistics Monitoring System

为提高农用车辆视觉导航系统对不同环境的适应性,基于GSM无线通信和嵌入式系统,提出了一种新的农业运输车辆自主导航的物流监控系统设计方法,并研究了其对路径的识别能力。该系统对环境的适应能力较强,可以快速、准确地提取导航路径的特征,并具有物流跟踪监控功能,可以实现农用运输车辆在特定的田垄里进行自主换向,提高了车辆的自主导航能力。利用GSM无线通信导航技术对驾驶员实际输出转角进行追踪测试,结果表明:驾驶员的目标曲线和转角无线控制实测曲线比较吻合,从而验证了基于GSM通信的嵌入式物流系统在农业运输车上实现自主导航的可行性和可靠性。

In order to improve the adaptability of the vision navigation system for the agricultural vehicles, the design method of the logistics monitoring system is proposed based on GSM wireless communication and embedded system. The system on the environment of good adaptability, can quickly and accurately extract the navigation path feature, and it has a logistics tracking monitoring function, which can realize agricultural transport vehicles, in particular furrows self-re- versing, and improve the vehicle autonomous navigation capabilities. GSM wireless communication navigation technology is used to track the actual output angle of the driver. The test results can be seen that the driver/s target curve and the angle of the measured curve is consistent. It validates the feasibility and reliability of the embedded logistics system based on GSM communication in the agricultural transport vehicle.
