多功能智能循迹避障小车的设计与实现

Design and Realization of the Multi-functional Intelligent Obstacle Avoidance Tracking Cars

基于STC89C51单片机对小车的智能控制,调节小车在行驶过程中的速度与方向,安装两组TCRT500红外对管检测路面的黑色轨迹,由舵机和超声波测距模块HC—SR04组成的避障模块来检测行驶前方是否有障碍物,从而实现小车的自动循迹和避障的功能。经实际测试,各组成部分协同工作可实现小车的智能避障和循迹的功能,且小车运行安全稳定。

Based on 51 MCU,the car is controlled intelligently by adjusting the speed and direction under driving situation. In order to achieve the functions of the car＇automatic tracking and obstacle avoidance,we install two groups of infrared tube TCRT500 to detect pavement black trajectory,and use obstacle avoidance module to detect whether there is any obstacle ahead of the driving,the model is composed of steering engines and ultrasonic distance measuring module HC-SR04. The test results indicate that all components of the car can work together to realize obstacle avoidance and automatic tracking,and the running of the car is safe and stable.
