智能避障小车设计 摘要 智能汽车作为曾经在科幻电影中出现的场景， 目前已经在逐步走进我们的生 活。从最简单的倒车雷达到现在的自动驾驶， 汽车智能化的概念已经深深的被社 会接收，而且汽车智能化的需求也越来越明显。 如何真正的使汽车能够自动无人 驾驶是现在科研的主要方向。 而智能小车作为智能汽车的一个缩影，无论是在国内还是国际的各种比赛 中，它的身影永远是最亮眼的一耳光，众多的方案也层出不穷。 本文的研究目的即是设计一种可以自动避障的小车， 自动避障顾名思义， 即 是能够自动躲避行进路上的障碍物。 本文首先对系统方案进行了详细的论述。 然后就方案中的硬件系统设计和软 件系统设计分别进行阐述。在硬件系统设计中，主要针对超声波测距 IC 和主控 MCU 进行讲解。软件系统设计中，主要针对系的要求进行了论证。最后，讨论 了本系统的可延展性。 关键词： STM32 ，无线传输，超声波测距 1 智能避障小车设计 Abstract Intelligent vehicle as appeared in the sci-fi movie scene, at present has been gradually came into our life. From reversing radar, the most simple to the automatic driving now, concept car intelligent has deep social reception, and the intelligent car demand is more and more obvious. How to make the car can automatically unmanned is the main direction of scientific research today. The intelligent car as an epitome of intelligent vehicle, whether in domestic or international competitions, its shadow is always a slap in the face of the most brisk, many of the programs are also emerge in an endless stream. The purpose of this study is to design a kind of automatic obstacle avoidance car, automatic obstacle avoidance as the name implies, is able to automatically avoid obstacles along the way. This article first has carried on the detailed elaboration to the system scheme. Then the hardware design and software design scheme are described. In the design of the hardware system, mainly in ultrasonic ranging IC and MCU control to explain. The design of software system, mainly for system requirements are discussed. Finally, the system scalability is discussed. Keywords :STM32,wireless transm
