基于单片机的自动割草机器人设计

基于单片机的自动割草机器人设计摘要高效、智能的割草作业需求在现代园林养护与草坪经营领域日益突出。传统人工割草在劳动强度大、劳动效率低的同时，耗费大量人力和时间：但现有的部分机械割草设备，在复杂地形复杂的情况下，由于缺乏对复杂地形进行精确控制、灵活应变的能力，在一定程度上可以提高效率。在这样的背景下，为满足不同场景草坪维护需求的自动割草机器人研发意义重大，其可大幅降低人力成本，提高割草作业的精确性和智能化程度。课题的学习按照由整体到局部，由理论到实践的思路进行研究。一是通过广泛的文献研究及市场分析，对本课题的研究方向和重点进行全面了解，进而弄清国内外割草机器人的研究现状及发展趋势。然后再从整体方案的设计做起，对机器人的整体架构、技术指标等进行科学的确定。然后分别展开传感系统和控制系统的详细设计，并在此过程中对各部分之间的兼容性、协同工作能力进行充分考虑，并进行深入的钻研Proteus模拟验证。关键词：自动割草机器人：单片机控制：路径规划ABSTRACTIn the world of modern garden maintenance and lawn management,the need forhigh efficiency and intelligence in lawn mowing operations is increasingly obvious.Traditional manual mowing not only consumes a lot of manpower and time,but alsohas high labor intensity and low efficiency;Some existing mechanical lawn mowingequipment,although capable of improving efficiency to a certain extent,lacks theability to accurately control and flexibly respond to complicated terrain.In this regard,the development of automatic lawn mowing robots is very important,as it candrastically cut labor costs,improve the accuracy and intelligence of lawn mowingoperations,and meet the maintenance needs of lawns in different situations.The process for going from the whole to the parts,and from theory to practice isthe basis for this research.First,from a thorough literature research and marketanalysis,it is easy to comprehend the research status and development trends ofdomestic and foreign lawn mowing.Furthermore,clarify the study direction and focus of this topic.Starting from thewhole scheme design,scientifically determine the general architecture and technicalindicators of the robot.Subsequently,detailed designs were carried out for the sensingsystem and control system,taking into accountthe compatibilityand collaborativecapabilitiesbetween each part,and doing in-depth research and Proteus simulationverification.The design goal of an automatic lawn mowing robot based on amicrocontroller was successfully realized,providing an effective technical answer forthe intelligence of lawn mowing operations.Key words:automatic lawn mower robot;Single chip microcontroller control;PathPlanning目录第1章绪论.1.1研究背景.1.2研究意义1.3国内外研究现状...21.3.1国外研究现状1.3.2国内研究现状、3第2章系统整体设计…2.1方案选择2.2系统总体框架.5第3章系统硬件设计.63.1AT89C51单片机.3.1.1AT89C51主要性能参数..63.1.2AT89C51引脚...63.2传感器模块.…3.2.1测速装置模块..83.2.2碰撞检测.83.3驱动模块..93.4红外遥控模块...103.5浮动开关模块.113.6复位模块.113.7液晶显示模块14第4章系统软件设计.154.1总体软件流程..154.2红外发射电路流程.164.3红外遥控系统流程174.4驱动系统流程…184.5割草避障系统流程.19第5章系统仿真215.1系统仿真界面.215.2系统待机状态仿真.215.3系统割草机控制状态仿真.225.4系统割草机运行状态仿真…23结论25参考文献.26
