基于单片机的多功能智能小车设计
摘要:近几年,我国经济的迅速的增长使得小车的销售量逐渐升高,2016年,,%。汽车数量的日益增多使得交通拥挤的现象越来越严重,因此,交通事故的发生的频率也在逐渐的增多。为了提高小车运行的安全,本文提出了一种基于单片机的多功能智能型小车的设计。
本文以STC89C51的单片机为核心,设计了一款多功能的智能小车,由于STC89C51的单片机在市场上受到了消费者普遍的好评,利用它进行智能小车的设计,既满足了大众的需求,又提高了小车设计的性能。同时,本文还结合了直流电机L298N型号的驱动芯片、E18-D80NK 红外避障传感器、TCRT5000红外反射式接近开关传感器对智能小车的整体进行了构架。

Abstract
In recent years, China's rapid economic growth makes the car sales gradually increased, in 2016, China's new energy vehicle sales reached 517,000, sales rate increased by %. The increasing number of cars makes traffic congestion more and more serious, so the frequency of traffic accidents is gradually increasing. In order to improve the safety of car operation, this paper presents a multi-functional intelligent car based on single-chip design.
In this paper, STC89C51 single-chip as the core, designed a multi-functional smart car, as STC89C51 microcontroller in the market by consumers generally praise, use it for intelligent car design, both to meet the needs of the public, but also improve The performance of the car design. At the same time, this article also combines the DC motor L298N model driver chip, E18-D80NK infrared obstacle avoidance sensor, TCRT5000 infrared reflector proximity switch sensor on the overall structure of the smart car.
Key Words: Single-chip; multi-function; intelligent car; design
