1、毕业设计(论文)报告题目基于单片机的智能化避障小车设计机电工程院(系)电气工程及其自动化专业学号100616007学生姓名***指导教师****起讫日期2014/01/01——2014/04/30设计地点********摘要摘 要随着社会的发展和科技的进步,各种各样的高科技开始出现在人们眼前,作为一名工科男更应该跟上时代的脚步,与时俱进不断创新。说到高科技,汽车应该是大家最常接触,也是广大男生更为关注的话题。智能汽车更是所有男生的追求,那么智能汽车的概念提出以后将给我们今后的生活带去怎样的变化呢?在当今科技如此迅猛发张的形势下,智能汽车成为了时代发展所不可阻挡的趋势
2、,我国作为一个科技大国,在汽车领域的研究也在不断的深入,虽然我们现在就汽车领域而言与国外还有一定的差距,但是我们通过对科技的不断研究,一定会超越他们的。在这种情况下,智能化避障小车的设计就很有意义。虽然我们做的只是最简单,基础的设计,但是这能为许多人打开一扇窗户,让他们走进来,为我国今后的科技发展贡献一份力量。本此设计中所设计的智能化避障小车是通过安装在小车头部的避障模块感应障碍物的距离,然后将感应到的信号传送到STC89C52单片机组成的控制系统,再由控制系统对L289N芯片控制的电机驱动模块发出信号指令,来控制小车后面两个轮子上电机的运行于停止,从而使小车完成避
