本文介绍了一种基于双传感器的双向报警主动安全预警系统,通过系统硬件组成及软件流程等设计方案的研究,实现实时、准确、低虚警率的预警系统。该系统可对设定宽度范围内车辆进行准确检测,同时进行双向报警,防止追尾碰撞,减少交通事故的发生。填补了目前国内市场在降低预警率系统领域研究的空白,具有重要的参考价值。 This paper introduces a two-sensor based on two-way alarm active safety early warning system, through the system hardware components and software design and other programs to achieve real-time, accurate, low false alarm rate early warning system. The system can set the width of the vehicle within the scope of accurate detection, at the same time two-way alarm to prevent rear-end collision, reduce traffic accidents. It has filled the blank of the domestic market in the field of reducing the warning rate and has an important reference value.
