The invention discloses a non-blind area real-time monitoring and alarming system for highway sudden accidents, belongs to the field of photoelectricity, and can solve the problems that the existing whole-course information monitoring of the highway is lack of all-road-section, all-weather and timeliness, is easily restricted by severe environments such as rainy, foggy and snowy days or unclear sight at night and the like. The system comprises a distributed sound wave detection optical cable, a sound wave signal demodulator, a network switch, a work station and a monitoring terminal. Through a sensing optical fiber network composed of a series of reflection nodes distributed at equal intervals, sound wave signals generated when traffic accidents happen are monitored at a high speed in real time without blind areas, the traffic accidents are accurately positioned by analyzing frequency components, and alarm information is sent in time. Real-time on-line monitoring and timely alarm without blind areas along the highway are achieved, linkage is carried out through a local area network and a video and unmanned aerial vehicle inspection system, accurate positions and types of faults are provided, and large-capacity and long-distance distributed sound wave monitoring is achieved.

    一种高速公路突发事故无盲区实时监测与报警系统,属于光电领域,可解决现有高速公路全程信息监测缺乏全路段、全天候和及时性,易受到雨雾雪天等恶劣环境或深夜视线不明等条件制约等问题,本系统包括分布式声波探测光缆,声波信号解调仪,网络交换机,工作站和监控终端。通过一连串等间距分布的反射节点组成的传感光纤网络,高速、实时无盲区地监测交通事故发生时产生的声波信号,通过分析频率成分组成,准确定位交通事件,及时发送报警信息。实现高速公路沿线无盲区实时在线监测与及时报警,并通过局域网络与视频和无人机巡视系统进行联动,提供故障的准确位置和类别,实现了大容量、长距离的分布式声波监测。
