Research on Tunnel Safety Early Warning System Based on Laser Radar Detection

为提高隧道的安全预警和处置能力,本文研究了一种基于激光雷达检测的隧道安全预警系统。首先在分析公路隧道安全预警需求的基础上,设计了包含入口激光式扫描传感器和抓拍相机、出口激光式扫描传感器和抓拍相机、工控机等组成的预警系统;接着从系统运行、车型检测、车辆出入口匹配、车辆变道检测四个方面研究了系统运行原理;最后就系统实际运行效果进行分析。实际运行数据分析结果表明,本系统能有效地检测交通事件,准确快速的达到预警效果,为隧道安全预警提供一种新的设计和实现方法。

In order to improve the safety early warning and disposal capability of tunnels,this paper studies a tunnel safety early warning system based on laser radar detection.Firstly,based on the analysis of highway tunnel safety warning requirements,an early warning system consisting of inlet laser scanning sensor and capture camera,export laser scanning sensor and capture camera,industrial computer is designed.Then,the operation principle of the system is studied in four aspects:from system operation,vehicle type detection,vehicle entrance and exit matching and vehicle lane change detection.Finally,the actual operation effect of the system is analyzed.The actual operation data analysis results show that the system could effectively detect traffic events,accurately and quickly achieve early warning effects,and provide a new design and implementation method for tunnel safety warning.
