The invention firstly provides intelligent safety early warning equipment for expressway roads to solve the technical problems that traditional vehicle lane departure and lane occupation behaviors cannot be reliably and actively monitored, and a vehicle recognition device is high in cost and large in transformation difficulty, and comprises a road surface end which is paved on an expressway detection road surface and is used for monitoring the position of a vehicle. An infrared transmitting circuit and an infrared receiving circuit form an infrared coverage area covering a monitoring area of the road surface end, and the road surface end comprises a transmitting antenna attached to a part of or all positions of the monitoring area; the corresponding vehicle-mounted end comprises a radio frequency receiving circuit coupled with the radio frequency transmitting circuit, when the vehicle enters the monitoring area, the radio frequency receiving circuit is excited and generates a corresponding electric signal, and when the electric signal is generated, the vehicle-mounted end sends out an alarm signal to remind people in the vehicle.
本发明首先提供一种高速公路道路智能安全预警设备,以解决传统的车辆车道偏离道路、占用车道行为无法可靠地主动监控,以及车辆识别装置成本高改造难度大的技术问题,包括铺装于高速公路检测路面的用于监测车辆位置的路面端,红外发射电路与所述红外接收电路形成覆盖路面端监测区的红外覆盖区域,路面端包括附着在监测区部分或全部位置的发射天线;对应的车载端包括与所述射频发射电路耦合的射频接收电路,当车辆进入所述监测区时,射频接收电路受激发并产生对应电信号,当该电信号发生时,所述车载端发出告警信号提醒车内人员。
