智能大棚导轨式无人耕种系统设计 毕业论文+任务书+cad图纸+proe三维图+程序
摘 要
随着农业现代化的发展和农业产业结构的调整，无人耕种机得到快速发展，其机械性能也越来越受到人们的关注。无人耕种机在工作时由于各种原因不可避免地会出现漏播现象，无法确保精播质量。为了提高无人耕种机的工作质量和智能化水平，本次设计智能大棚导轨式无人耕种系统在大棚里实现无人化耕种。
本次大棚导轨式无人耕种机控制系统采用ATMEGA128单片机作为主芯片。单片机先对增量式编码盘采集的信号进行分析处理得到机具的速度，然后根据所建立的数学模型，通过算法编程控制伺服电机的转速来实现智能耕种，其中为了精准耕种还设计两个反馈系统：伺服电机转速的反馈和实际耕种量的反馈。具有自动行驶、自动耕地、自动耕种、检测障碍物、防撞的功能。该平台应具有智能化、小型化、经济实用等特点。

Abstract
With the development of agricultural modernization and the adjustment of agricultural industrial structure, the unmanned farming machine has been developed rapidly, and its mechanical properties have attracted more and more attention. Unmanned farming machine in the work due to various reasons will inevitably appear leakage phenomenon, can not ensure the quality of fine sowing. In order to improve the working quality and intelligent level of unmanned farming machine, this design of intelligent greenhouse guide rail unmanned farming system in the greenhouse to achieve unmanned farming.
ATMEGA128 single chip is used as the main chip in the control system of the guide rail type unmanned farming machine in the greenhouse. The single chip microcomputer first analyzes and processes the signal collected by the incremental coding disk to obtain the speed of the machine, and then according to the established mathematical model, the speed of servo motor is controlled by algorithm programming to realize intelligent seeding. Two feedback systems are designed for accurate seeding: servo motor speed feedback and actual seeding feedback. It has the functions of automatic driving, automatic cultivated land, automatic sowing, detecting obstacles and collision prevention. The platform should be intelligent, miniaturized, economical and practical.
