多功能智能小车

摘要

近些年来，随着我国改革开放政策的不断发展与深入，我国对科教科研事业的大力投入使得电子电器技术得到飞速发展，人民群众的生活方式变得多姿多样，幸福感也逐渐提高；同时各种高档化、智能化家电产品成为大多数家庭的必需品。在这个时期，微电子技术的发展和各行各业测量的需求，给系统的开发及智能化研究带来了非常好的契机，具有一个非常广阔的发展前景。智能作为现代迅速发展的领域，同时，也是以后整个社会的一个新的特点。智能小车，能够按照预人们事先设定的模式，在一个固定的环境里自动灵活的运作，在执行任务中不需要过多的干涉；同时，科学勘探中此设备也会有用武之地。在智能小车的基础上，操作者可以将蓝牙技术相结合，得到的设备会变得更智能、更强大。蓝牙技术在近些年来发展十分迅速，成为科学界与信息界的一项热门技术。多功能智能小车，该设备将单片机与蓝牙控制技术相结合，再将手机与小车的控制结合为一体，将智能与蓝牙控制完美的结合。

本文主要对多功能智能小车进行了一些学习和研究，小车具有蓝牙遥控、智能寻迹、自动避障等功能。其中，STC89C52单片机，作为小车的系统控制核心；系统的驱动部分为单向直流电机，再加上超声波接收器，实现了小车前进后退、加速减速、左右转向、自动避障、收集温度信息和智能蓝牙遥控导航。软件部分通过C语言进行编程，语言通俗易懂，同时可以根据需求不同进行改动。整个系统实用、稳定，设计具有一定的发展前景。

MULTI-FUNCTION INTENLLIGENT CAR

Abstract

In recent years, with the continuous development and deepening of China's reform and opening up policy, to strongly committed to the cause of science and education research in our country makes electronic technology rapid development. People's lifestyle has become diverse, happiness also gradually improved. At the same time, a variety of high-end and intelligent home appliances has become a necessity for most families. During this period, demand for development of microelectronic technology and all walks of life measurements, to the system development and research of intelligent brought very good opportunity, has a very broad prospects for development. As the rapid development of modern intelligent field, at the same time, the whole society will be a new feature. In a stationary environment, smart car, which can be set in advance in accordance to the people, is automatic and flexible operation, and it do not need too much interference in the implementation of tasks; At the same time, this device will be very useful in scientific exploration. In the smart car based, the operator which can combine Bluetooth technology will become more intelligent, more powerful. Bluetooth technology is developing very rapidly in recent years, and it has become a popular technology in science and information industry. Multifunctional intelligent car, which combining MCU and Bluetooth control technique and connecting with mobile phone and car control as a whole, is a perfect production.

In this paper, we mainly study the design of a multifunctional intelligent vehicle, which has the Bluetooth remote control, intelligent tracking, automatic obstacle avoidance function. The STC89C52 microcontroller is the car's core system control; System, driven by unidirectional DC motor and coupled with the ultrasonic receiver,
