Automobile ultrasonic fly's eye system based on CAN bus and ultrasonic distance measurement

BIAN Li-yun,WEI Min-xiang(College of Energy and Power Engineering,Nanjing University of Aeronautics and Astronautics,Nanjing 210016,China)  
Imitating fly's eye,automobile ultrasonic fly's eye system based on CAN bus and ultrasonic distance measurement is designed.The system is used on anti-collision and alarm.Single-chip is used as the core of the system,and the compound eye of the system is composed of sixteen ultrasonic sensors.The feasibility of omnidirectional vehicle obstacle avoidance is realized by arranging the sensors rationally.The structure,principle and software of the system are described in detail.The experiments show the high timeliness,reliability and stability of the system.The demands of vehicle low-speed anti-collision is achieved.
