The invention relates to the field of charging pile fault early warning, and particularly discloses an electric vehicle charging pile fault early warning system and method based on big data. According to the method, firstly, a charging head image, collected by a camera, of an electric vehicle charging pile, current values, collected by a sensor, of the charging pile in the charging process at multiple preset time points and voltage values, collected by the sensor, of the charging pile in the charging process at the multiple preset time points are obtained; the three parts are subjected to feature extraction and correlation analysis, and finally a classification result is obtained through a classifier to judge whether the charging head of the charging pile has a fault or not, so that real-time monitoring and early warning are realized, the reliability of the charging pile is improved, and a better charging service is provided for a user.

    本申请涉及充电桩故障预警领域,其具体地公开了一种基于大数据的电动汽车充电桩故障预警系统及方法,其首先获取由摄像头采集的电动汽车充电桩的充电头图像、由传感器采集的充电桩多个预定时间点的充电过程中的电流值和由传感器采集的充电桩多个预定时间点的充电过程中的电压值,然后利用深度学习技术,对三者进行特征提取和关联分析,最后通过分类器得到分类结果,以判断充电桩充电头是否存在故障,进而实现实时监测和提前预警,以提高充电桩的可靠性,从而为用户提供更好的充电服务。
