基于毫米波雷达的高速公路动态警示系统设计

针对现有交通诱导显示系统不能实时显示道路交通状态、动态限速不能实时反馈交通事件等问题,本文基于毫米波雷达,融合诱导显示、违法采集、CAN通讯、4G通讯等技术,设计了包含系统控制软件、移动应用软件、多功能单元和检测单元等在内的动态警示系统,实现对道路通行状态全天候全天时监测,并实时对临近区域的机动车驾驶人进行警示,从而为减少高速公路交通事故的发生提供了可能。

Aiming at the problems that existing traffic guidance display systems cannot display real time road traffic status and dynamic speed limits cannot reflect the traffic incidents in real time,in this paper,based on millimeter wave radar and fused technologies including guidance display,illegal behavior collection,CAN communication,4G communication and others,the authors designed a dynamic warning system including system control software,mobile application software,multifunctional unit and detection unit,which could realize the 24h/7d monitoring of road traffic status and provide real time warnings to the motor vehicle drivers in neighboring areas,thus,made the realization of reducing the number of traffic accidents occurred on expressways possible.
