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，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。矚慫润厲钐瘗睞枥庑赖。 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，从而使小车完成避障功能。聞創沟燴鐺險爱氇谴净。

ABSTRACT

ABSTRACT

Along with social progress and technological development, a variety of high-tech began to appear in front of people, as a man should keep up with the pace of engineering times, the times and innovate. When it comes to high-tech, we should be the most contact with the car, but also the majority of the boys are more concerned about the topic. Proposed the concept of intelligent vehicle to the automotive industry also brought opportunities and challenges. Intelligent car is bound to be the future trend of the development of the automobile industry, in this context, we carried out a study of microcontroller-based obstacle avoidance smart car. China, as a scientific and technological power, in the automotive sector has also been studied in depth, although we first in the automotive sector and abroad for the purposes there is a gap, but we continue to study through science and technology, will be beyond their. In this case, the design of the intelligent car obstacle avoidance makes sense. Although we do is the most simple, basic design, but for many people it can open a window and let them come in, contribute to a future of technological development in China.残骛楼諍锩瀨濟溆塹籟。 Based infrared detection of black lines and the road obstacles, and use a STC89C52 MCU as the controlling core for the speed and direction, A electronic drived, which can automatic track and avoid the obstacle, was designed and fabricated. In which, the car is drived by the L298N circuit, its speed is controlled by the output PWM signal from the STC89C52. 酽锕极額閉镇桧猪訣锥。
