基于安卓的智能避障小车设计与实现

摘要:汽车是现代人生活必不可少的交通工具，其发展和运用大大加速了人类的

生活节奏，也对其他工业发展起到推动作用。汽车作为最终机械产品，其生产制

造及应用与其他设计、生产工业密不可分，同时人类对汽车的需求促进汽车产业

快速发展,汽车已经成为当代物质文明与进步的象征及文明形态的一种代表。但

随着汽车走进越来越多的家庭，交通拥挤的状况也越来越严重，交通事故频繁发

生，其中由于追尾、倒车碰撞产生的事故则占据了很大比例。在这种情况下，智

能避障小车的设计将改善这一问题。

该系统的设计主要以 STC89C52RC 为核心控制器，结合了超声波模块、

车不但可以用于需要测量距离参数的各种应用场合还可以用于一些娱乐场所、活

动。

Intelligent Obstacle Avoidance Car Design And

Implementation Based On The Android

Abstract: Car is an indispensable means of transport for modern life, and its

development and use have greatly accelerated the pace of human life, but also to

promote other industrial development. Automobile as the final mechanical products,

due to rear-end, reversing collision accidents are accounted for a large proportion. In

this case, the design of the intelligent barrier will improve the problem.

The system is designed mainly with STC89C52RC as the core controller ，

combined with the ultrasonic module, LCD1602 display module, motor drive module,

power module, Bluetooth module to achieve the intelligent car. The use of

multi-module is based on the design of the system program, and ultimately the

combination of software and hardware is completed the function of multiple modules.

The system achieves the principle of obstacle avoidance by the microcontroller, which

calculates the ultrasonic transmission to the receiving time and then calculate the

measured distance. And the measured data is displayed on the LCD1602 display, and

Bluetooth Module;
