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.
