The invention discloses a vehicle accident early warning method based on a block chain technology, and the method comprises the steps: recording an accident site of an accident vehicle, collecting accident information, transmitting the accident information to each node on a block chain, carrying out the authentication and storage, building a data model from multiple dimensions according to data features, carrying out the data processing of the data of the data model, and carrying out the early warning of a vehicle accident. Performing machine learning, training a neural network, adopting an MAPE mode evaluation model to evaluate whether a data model meets requirements or not, reading accident information in a certain area range from a block chain, judging whether the data model is an accident-prone place or not, and if the data model is the accident-prone place, judging the possibility of accident occurrence by utilizing an LSTM algorithm, and obtaining an early warning level. If it is judged that the early warning conditions are met, the early warning conditions are synchronously sent to nearby vehicles, and cross early warning is carried out; the method has the advantages that vehicle accident information is open, accident early warning accuracy is high, and accident early warning is achieved through cross reminding.

    本发明公开了一种基于区块链技术的车辆事故预警方法,包括:记录事故车辆的事发地点,采集事故信息,将事故信息发送到区块链上的各个节点,进行认证和存储,根据数据特征,从多个维度建立数据模型,对数据模型的数据进行数据处理,进行机器学习,训练神经网络,采用MAPE方式评估模型对所述数据模型是否符合要求进行评估,从区块链中读取一定区域范围内的事故信息,判断是否为事故多发地,如果处于事故多发地,则利用LSTM算法判断事故发生的可能性,并得出预警等级,如果判断符合预警条件,则将预警情况同步发送给附近车辆,进行交叉预警;本发明具有车辆事故信息公开,事故预警准确度高,交叉提醒实现事故预警的效果。
