The invention provides a fault detection method and system for a battery charging cabinet of an electric bicycle, and relates to the technical field of charging fault detection, and the method comprises the steps: dividing a day into four time intervals according to high and low peak power consumption, and setting different weight coefficients; acquiring load power, voltage, current and temperature time sequence data, and calibrating the load power by using the voltage, the current and the temperature; calculating the average power, the maximum power and the minimum power of each time interval; acquiring load power, voltage, current and temperature data of the to-be-detected charging cabinet; calibrating load power and calculating average power, maximum power and minimum power of the load power; and combining the weight coefficient, the average power, the maximum power and the minimum power to generate an abnormal fault index, comparing the index with a preset threshold value, and judging whether the charging cabinet has a fault or not. According to the method, the abnormal fault index is generated by collecting and calibrating the time sequence data of each parameter and combining the time interval and the weight coefficient so as to judge whether the electric bicycle battery charging cabinet breaks down or not.

    本发明提供一种电动自行车电池充电柜的故障检测方法及系统,涉及充电故障检测技术领域,本发明通过将一天按高低峰用电划分为四个时间区间,设置不同权重系数;采集负载功率、电压、电流和温度时序数据,利用电压、电流和温度校准负载功率;计算各时间区间的平均功率、最大功率和最小功率;采集待检测充电柜的负载功率、电压、电流和温度数据;校准负载功率并计算其平均功率、最大功率和最小功率;结合权重系数、平均功率、最大功率和最小功率生成异常故障指数,将该指数与预设阈值比较,判断充电柜是否出现故障。本发明通过采集并校准各个参数时序数据,结合时间区间和权重系数,生成异常故障指数,以判断电动自行车电池充电柜是否出现故障。
