路段感应式夜间行人过街预警系统设计

Design of the Road Induction Pre-warning System for Pedestrian Crossing at Night

为了解决夜间行人过街与机动车之间存在的侧向冲突问题,避免夜间行人过街路段存在的安全隐患,设计了一种基于夜间行人过街的安全预警系统。该系统结合环形感应线圈测距传感器、压电传感器、红外线传感器等相关硬件设备,建立夜间安全行驶智能预警系统。在此系统基础上进行数值仿真分析,利用LED预警板向行人和驾驶人发布预警信息,成功保障行人过街安全,促使驾驶人主动减速、行人及时避让,降低了夜间无信号灯路段事故发生的概率。

In order to solve the problem of lateral conflict between pedestrian crossing and motor vehicles at night and avoid the potential safety hazards of pedestrian crossing at night,a safety pre-warning system based on pedestrian crossing at night is designed.This system combines the related hardware equipment of ring induction coil ranging sensor,piezoelectric sensor,and infrared sensor and so on,and establishes an intelligent pre-warning system for safe driving at night.On this basis,it uses LED pre-warning board to issue pre-warning information to pedestrians and drivers.The system successfully guarantees pedestrians crossing the street safely and urges the driver to slow down actively and the pedestrians to avoid in time,which reduces the probability of accidents occurring on the road without signal lights at night.
