基于单片机的智能小车控制
摘要:智能化作为现代电子产品的新趋势,是今后的电子产业的发展方向。智能化设计的电子产品可以按照预先设定的模式在一个环境里自动运作,不需要人为的管理,可应用于科学勘探、环境监测、智能家居等方面。基于单片机的智能小车控制就是其中的一个体现。本设计实现了一种基于51单片机的自动避障智能模型车系统,通过红外传感器采集路况信息,通过对检测信息的分析,自动控制转向电机转向,改变行驶路径,绕过障碍物,从而实现车稳定避障。
本课题设计的智能小车,具有自动避障功能,超声波测距报警,无线电遥控等功能。

Smart car based on SCM control
Abstract:As a new trend of modern electronic products, intelligent is the developmental direction of electronic industry after then. Electronic products, which are intelligently designed, can automatically operate following the mode that is pre-set. Without the management of human beings, it can be used for scientific exploring, environmental monitoring, intelligent home furnishing, etc. One of the embodiments is the intelligent control car which is based on single chip puter. In the design, an intelligent model car system based on MCU 51 has been realized. It can collect traffic information with infrared sensors. Meanwhile, by the analysis of information examined, it can transfer from automatic control to motor steering in order to change the route and dodge the obstacles so that the steady avoidance of the barrier e true.
In this paper, a car with the ability of intelligent judgment has been designed and made. It functions as the device which can dodge obstacles automatically, alarm with ultrasonic distance examination, and remote control by radio.
