The invention discloses a highway vehicle abnormal behavior early warning system based on 5G communication, and the system comprises the steps: obtaining vehicle data and transmitting the vehicle datato an intelligent RSU when a vehicle is driven into a detection range of the intelligent RSU and a roadside sensor; enabling the intelligent RSU to carry out weighted fusion processing on the data with the same physical address and too small time difference; performing multi-stage judgment on vehicle behaviors by utilizing condition judgment and a recurrent neural network model; and finally, outputting probability matrixes of the vehicles belonging to different behaviors in the time period, comparing the probability matrixes of the different behaviors with behavior combination data stored ina database, determining vehicle behaviors according to the similarity, determining corresponding reminding information according to the behaviors, and sending the reminding information to the corresponding vehicles; if the similarity is lower than the threshold value, sending the data to an information processing center, carrying out secondary processing on the data by the information processing center, and directly sending a corresponding prompt to the vehicle. According to the invention, more accurate vehicle behaviors can be obtained in the vehicle identification process, and the timelinessof data transmission is improved.
本发明公开了一种基于5G通信的高速公路车辆异常行为预警系统,当车辆驶入智能RSU以及路侧传感器检测范围内时,获取车辆数据并传输给智能RSU;智能RSU对物理地址相同以及时间差过小的数据进行加权融合处理,利用条件判断和循环神经网络模型进行对车辆行为多级判断,最后输出车辆该时间段属于不同行为的概率矩阵,将不同行为的概率矩阵与数据库中存储的行为组合数据对比,由相似度确定车辆行为,再由行为确定对应的提醒信息,发送到对应车辆;如果相似度低于阈值,则将数据发送到信息处理中心,由信息处理中心对数据进行二次处理,并向车辆直接发出相应的提示。本发明在车辆识别过程中能够得到更加准确的车辆行为,同时也提高了数据发送的及时性。
