The invention discloses a safety early warning system for urban rail transit, which comprises an intelligent operation host, a data acquisition unit and a sound-light alarm device, and is characterized in that a laser radar, a millimeter wave radar and two visual detection modules are respectively mounted at one end of the front surface of the data acquisition unit; the laser radar and the millimeter wave radar are in telecommunication connection with the intelligent operation host through an Ethernet cable and a power line. According to the invention, the laser radar, the millimeter wave radar and the visual detection module are selected to acquire real-time data, and on the basis of organic fusion of a plurality of detection technologies, the confidence coefficient setting of each sensor in different environments has mature, available and effective experience; redundancy, contradiction and data complementation possibly existing among information of multiple detection units can be eliminated to the maximum extent, and consistent interpretation and description of a detected object are obtained, so that rapidness and correctness of decision making, planning and reaction of a system are improved, and an accurate alarm is quickly made when foreign matter invades a limit.

    本发明公开了一种用于城市轨道交通的安全预警系统,包括智能运算主机、数据采集单元以及声光报警装置,数据采集单元正面的一端分别安装有激光雷达、毫米波雷达以及2个视觉检测模块,激光雷达和毫米波雷达皆通过以太网线和电源线与智能运算主机电信连接。本发明通过选用激光雷达、毫米波雷达以及视觉检测模块对实时数据进行获取,通过在多种探测技术有机融合的基础上,对各传感器在不同环境下的置信度整定有成熟可用且行之有效的经验,能够最大限度地消除多探测单元信息之间可能存在的冗余和矛盾,数据互补,获得被测对象的一致性解释与描述,从而提高系统决策、规划、反应的快速性和正确性,在有异物侵入限界时迅速做出准确报警。
