机械设计制造及其自动化毕业设计-无人飞行喷雾机设计

无人飞行喷雾机设计摘要本次设计的研究目的是针对农田播种与喷药自动化程度低，农业生产效率较低的问题进行解决。当前的农田种植还主要依靠于人力进行播种和喷药，存在着播种效率低，喷药人力成本高等问题，还存在一些地形难以进行种植的问题。基于这些问题，本次研究提出了基于51单片机的无人机播种与喷药系统硬件设计。本次设计采用51单片机作为控制核心，采用GPS定位技术，气压定高技术，电机控制技术，远程无线通信技术，实现了对农田的无人机播种与喷药。本次设计中主要有的功能包括实时反馈无人机高度、速度。能够根据输入的农田大小、风速、播撒物品及质量、作业地形等，调整当前的作业计划。能够有效的降低种植农田的人力成本，使播种效率更高，提高农药的喷洒均匀度，减少农药的使用，使农药的效果更好。关键词：单片机应用；无人机；播种；农田；DesignofunmannedsprayerAbstractTheresearchpurposeofthisdesignistosolvetheproblemsoflowautomationoffarmlandsowingandsprayingandlowagriculturalproductionefficiency.Atpresent,farmlandplantingmainlydependsonmanpowerforsowingandspraying.Therearesomeproblems,suchaslowsowingefficiency,highcostofsprayingmanpower,anddifficultplantinginsometerrain.Basedontheseproblems,thisresearchputsforwardthehardwaredesignofUAVseedingandsprayingsystembasedon51singlechipmicrocomputer.Thisdesignuses51singlechipmicrocomputerasthecontrolcore,GPSpositioningtechnology,airpressureheightsettingtechnology,motorcontroltechnologyandremotewirelesscommunicationtechnologytorealizetheplantingandsprayingofUAVonfarmland.Themainfunctionsinthisdesignincludereal-timefeedbackofUAVheightandspeed.Thecurrentoperationplancanbeadjustedaccordingtotheinputfarmlandsize,windspeed,sowingitemsandquality,operationterrain,etc.Itcaneffectivelyreducethelaborcostofplantingfarmland,improvethesowingefficiency,improvethesprayinguniformityofpesticides,reducetheuseofpesticides,andmaketheeffectofpesticidesbetter.Keywords:singlechipm
