The invention discloses a charging safety protection method based on multi-modal information input. The charging safety protection method comprises the following steps: S1, acquiring a video image of a charging vehicle, and identifying and classifying the video image; s2, vehicle type judgment is carried out, when it is judged that the vehicle is a passing accident type vehicle, a charging limiting strategy is adopted, and maintenance personnel are informed in real time to make judgment according to the actual situation; when it is judged that the vehicle type does not exist in the database, the battery model is further judged; when the vehicle is judged to be the vehicle of the known type, a charging strategy based on the health degree of the battery is adopted; s3, charging is carried out according to the selected charging strategy, a charging curve is monitored at the time interval of ten seconds in the charging process, and the difference value of a power curve is calculated in real time; s4, when the difference value of the charging curve exceeds an early warning threshold value, early warning information is sent out, and a platform and workers are informed of maintenance. According to the invention, a high fault pre-judgment success rate is realized, the safety problem in the charging process is reduced, and the safety protection level of the electric vehicle charging facility can be continuously improved.
本发明公开了一种基于多模态信息输入的充电安全防护方法,包括:S1、获取充电车视频图像并进行识别分类;S2、进行车型判断,当判断为过往事故类型车辆,则采取限制充电策略,并实时通知维护人员根据实际情况做出判断;当判断为数据库中不存在的车辆类型,则进一步进行电池型号的判断;当判断为已知类型的车辆,则采取基于电池健康度的充电策略;S3、以选择的充电策略进行充电,在充电过程中以十秒为时间间隔监控充电曲线,并实时计算功率曲线的差分值;S4、当充电曲线的差分值超过预警阈值时发出预警信息,通知平台及工作人员检修。根据本发明,实现较高的故障预判成功率,减少充电过程中的安全问题,能不断提高电动汽车充电设施的安全防护水平。
