The invention provides a charging pile fault automatic detection method and system based on a Mini-Batch-Kmeans algorithm, and relates to the technical field of power equipment anomaly detection. The method comprises the following steps: collecting traffic original message data of charging pile terminal equipment, and extracting key information from the traffic original message data to form a detection vector; a Mini-Batch-Kmeans clustering algorithm is used to establish a normal flow model; flow data of each time period is collected online and constructed into a detection vector, the detection vector is compared with a normal flow model, the normal flow vector is brought into the model to optimize model performance, abnormal flow triggers an alarm mechanism, and a detailed abnormal report is generated and reported to the distributed charging pile operation monitoring platform; when the system detects a fault behavior, a corresponding blocking measure is taken according to the property of the threat. According to the technical scheme, manpower and computing power cost can be saved, the function of the fusion terminal is expanded, and the safety defense line of a power grid is further consolidated.

    本发明提供了一种基于Mini‑Batch‑Kmeans算法的充电桩故障自动化检测方法及系统,涉及电力设备异常检测技术领域。该方法包括:收集充电桩终端设备流量原始报文数据,从中提取关键信息形成检测向量;利用Mini‑Batch‑Kmeans聚类算法建立正常流量模型;在线采集每个时间周期的流量数据,并将其构造成检测向量,与正常流量模型进行比对,正常流量向量将被纳入模型以优化模型性能,异常流量将触发告警机制,并生成详细的异常报告上报分布式充电桩运营监控平台;当系统检测到故障行为时,根据威胁的性质采取相应的阻断措施。本发明提出的技术方案可以节约人力和算力成本,扩充融合终端的功能,进一步巩固电网的安全防线。
