摘要
针对汽车带来的越来越严重的交通拥堵以及交通事故频繁发生的问题,设计了智能避障小车系统。该系统以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避障。该系统实现避障的原理是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,并在LCD1602显示屏上将测得的数据显示出来,用户可以按照显示的数据安全驾驶。实际测试证明: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,具有很强的实用性。
With more and more traffic congestion and traffic accidents, this paper designs a smart obstacle avoidance system for cars. The STC89C52RC is used as the core controller in this system. It consists of ultrasonic module, LCD1602 display module, motor drive module, power supply module and Bluetooth module. Its principle is that the single chip machine is used to calculate the time form sending to receiving by the ultrasonic wave and the distance measured. The data measured is displayed on the LCD1602 display, and the car can be safely drived according to the data. The experimental result shows that the system has the advantages of low cost, easy to control, reliable work, high accuracy of ranging, readability and clear process.
