The invention discloses a vehicle-mounted traffic accident early warning device based on cloud edge combination, which is used for solving a problem of providing intelligent early warning based on historical accident information, a current vehicle speed and road environment information before a road traffic accident occurs. The device comprises an accident data acquisition module, a cloud platform, an accident model prediction module, a vehicle-mounted terminal, a GPS positioning module, a trigger early warning module and a weather early warning module. The accident data acquisition module comprises an accident data acquisition unit and a non-accident data acquisition unit, and the accident data acquisition unit is used for acquiring accident data and sending the accident data to the cloudplatform. Weighted model training is performed through a strategy tree, a neural network, a support vector machine and a multiple regression model, advantages of multiple models are concentrated, andprediction result joint optimization and accuracy are achieved; forecast information is displayed and broadcasted by a voice through the vehicle-mounted terminal; and intelligent early warning is achieved by carrying out trigger analysis on a driven vehicle, a person and an environment.

    本发明公开了一种基于云边结合的车载交通事故预警装置,用于解决在道路交通事故发生前提供基于历史事故信息、当前车速及道路环境信息提供智能预警的问题;包括事故数据采集模块、云平台、事故模型预测模块、车载终端、GPS定位模块、触发预警模块和天气预警模块;事故数据采集模块包括事故数据采集单元和非事故数据采集单元;事故数据采集单元用于采集事故数据并将事故数据发送至云平台内;本发明通过策树、神经网络、支持向量机及多元回归模型进行加权模型训练,采用集中多个模型优势,实现预测结果联合最优化以及准确度;通过车载终端对预报信息进行显示和语音播报;通过对驾驶的车辆和人以及环境进行触发分析,实现智能预警。
