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、LCD1602显示屏模块、电机驱动模块、电源模块、蓝牙模块从而实现小车的智能化。在采用的多模块基础上的设计了系统方案，最终经过软件和硬件相结合完成了多个模块的功能。该系统实现避障的原理是由单片机通过定时器计算超声波发送到接收的时间再算出实测距离。并且在LCD1602显示屏上将测得的数据显示出来，用户也可以按照显示的数据安全驾驶。该系统具有成本低廉、易控制、工作可靠、测距准确度高、可读性强和流程清晰等优点。基于安卓的智能避障小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。 关键词：STC89C52RC；LCD1602；超声波；蓝牙；  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, its manufacturing and application are closed to other design and production industry.while the human demand for the automobile to promote the rapid development of the automobile industry, the car has become a symbol of contemporary material civilization and progressive symbol of civilization and a representative. Nowadays the car has entered more and more families, meanwhile traffic congestion situation is more and more serious, frequent traffic accidents, which 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 calculate
