The invention relates to the technical field of vehicle-road cooperation, in particular to a ramp afflux-in and afflux-out early warning system, which comprises the following components: C1, a vehicle detection triggering unit: when a vehicle runs on a ramp, a thunder-sight fusion all-in-one machine sends out an early warning signal, and finally, the early warning signal is respectively transmitted to a vehicle early warning prompt unit and an RSU data communication unit through two information links; C2, a vehicle early-warning prompt unit: a control panel receives a control signal from the LORA receiving end, an LED information board is linked to pop up early-warning text information, and warning is given out to passing vehicles; C3, a RSU data communication unit: when the RSU data communication unit receives the data, the data are respectively sent to a vehicle-mounted OBU and a cloud platform, the vehicle-mounted OBU broadcasts early warning information, and the cloud platform further processes the data; after the ramp vehicle normally passes, the early warning signal disappears, the LED information board does not pop out early warning text information any more, and the RSU data communication unit does not broadcast the early warning information any more.
本发明涉及车路协同技术领域,尤其为一种匝道汇入汇出预警系统,其包括以下组成内容:C1,车辆检测触发单元:当有车辆驶上匝道时,雷视融合一体机发出预警信号,最终通过两条信息链路分别传递给车辆预警提示单元和RSU数据通信单元;C2,车辆预警提示单元:控制板接收来自LORA接收端的控制信号,联动LED情报板弹出预警文字信息,对过往车辆发出警示;C3,RSU数据通信单元:当RSU数据通信单元接收到数据时,将数据分别发送至车载OBU和云平台,车载OBU广播预警信息,云平台进一步处理数据;匝道车辆正常通过后,预警信号消失,LED情报板不再弹出预警文字信息,RSU数据通信单元也不再广播预警信息。
