最新设计  毕业论文 AGV自动导引小车的设计,正文共35页,12112字,附任务书、开题报告、中期检查表、设计图纸、答辩文稿。
  摘要:
   AGV即自动导引小车,它集声、光、电、计算机技术于一体,综合了当今科技领域先进的理论和应用技术。广泛应用在柔性制造系统和自动化工厂中,具有运输效率高、节能、工作可靠、能实现柔性运输等许多优点,极大的提高生产自动化程度和生产效率。
  本文在分析研究国内外AGV现状与发展的基础上,设计了两后轮独立驱动的自动导引小车,其主要工作内容包括:小车机械传动设计、直流伺服电机的选择、AT89C51单片机控制系统硬件电路、运动学分析、控制系统软件设计及圆弧插补程序。所设计的小车能够实现自主运行、运动轨迹(圆弧、直线)的控制等功能,达到了沿着设定的路线行驶。
  关键词:自动导引小车,单片机控制,设计,PWM技术
  
   Abstract
   The AGV namely Automatic Guided Vehicle, it collect sound, the light, the electricity, the computer technology in a body, and synthesizes the technical domain advanced theory and the application technology. It widespread applied in the flexible manufacturing system and the factory automation, and has the merits of high transportation efficiency, the energy conservation, the work reliable, the flexible transportation. It enormously enhanced production automaticity and production efficiency.
   Based on the analysis of the domestic and foreign AGV present situation and its development foundation, AGV with two wheel independent drive is designed. The content of the paper includes: design of mechanical structure and drive of the car, the choice of direct current servo motor, the hardware electric circuit of AT89C51 control system, the kinematic analysis, the software design of control system and the procedure of interpolation the circular arc. The designed car can realize the functions of independent movement, the path (circular arc, straight line) control and so on, and has achieved to travel along the hypothesis route.
