摘　　要：设计了一种基于MSP430的超声波倒车雷达监测报警系统。系统能实时检测汽车尾部与障碍物的距离,并根据设定的距离值由蜂鸣器发出不同频率的警报信息反馈给司机,对行车或倒车安全有至关重要的作用,该系统最大测量距离达6.5米,具有成本低、非接触、速度快、精度高、可靠性强、适应性好、操作方便的特点。This paper introduces a real-time distance detection and alarm system using ultrasonic sensor. It is based on the MSP430 signal chip micro-computer. According to the driver to distance value set, the system can feedback warning information of different frequency to the driver. So it is a vital role in safety for the drive or roll back. The largest measuring distance of the system is 6.5m, and it has adrantages of the low cost, non-contact, high speed and accwracy, high reliability, adaptability, and easy operation, etc.
