The invention relates to the technical field of charging pile operation and maintenance, and provides a charging pile charging abnormity detection method and system, and the method comprises the steps: obtaining and recognizing a vehicle connection image corresponding to a charging abnormity signal, obtaining an image area proportion, carrying out the comparison, and judging whether the connection abnormity of a charging gun and a vehicle exists under the charging abnormity signal or not; when the comparison difference value is larger than the threshold value, it can be determined that connection is abnormal due to the foreign matter, then the position relation between the charging gun and the charging pile is recognized in the corresponding charging pile connection image, whether the charging fault is the foreign matter on the vehicle interface or the foreign matter fault on the charging gun is detected, charging fault detection of the charging pile is achieved, the operation and maintenance cost is reduced, and the charging efficiency is improved. The detection precision is improved.
本发明涉及充电桩运维技术领域,提供一种充电桩充电异常检测方法及系统,方法包括:通过对充电异常信号对应的车辆连接图像获取和识别,得到图像面积比例进行比对,判断充电异常信号下是否存在充电枪与车辆的连接异常,在比对的差值大于阈值后能确定连接因异物导致异常,进而再在对应的充电桩连接图像中进行充电枪和充电桩的位置关系识别,检测充电故障是在车辆接口上的异物还是充电枪上的异物故障,实现充电桩的充电故障检测,减少运维成本,提高检测精度。
