摘　　要：模仿苍蝇的眼睛,设计了一种先进的基于CAN总线网络和超声测距的汽车超声蝇眼系统,用于汽车低速防撞和预警。系统采用单片机作为控制核心,系统的"复眼"由汽车周围安装的16只超声波传感器构成。通过对16只超声波传感器的合理布局,实现了车辆全方位避障。详细描述了系统的功能结构、工作原理和软件设计。实际运行结果表明:该系统在实时性、稳定性和测量精度方面都达到了较高的水平,能满足汽车的低速防碰撞要求。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.
