The invention discloses a high-voltage fault management method and system for a motor controller, and relates to the technical field of high-voltage faults of elevators. According to the method, abnormal conditions of an elevator door are monitored in real time through a structure three-dimensional model and data collection, and parameter changes of the motor controller are collected; particularly, the influence of the number of induction events CJ of abnormal incomplete closing of an elevator door every day and the duration time Ty of each abnormal door opening and closing on the abnormal change value of the door motor controller comprises real-time monitoring data of a first acceleration value sd +, a first deceleration value sd-, a first current load value fzz, a first vibration value zdz and a first temperature value wd; the high-voltage fault risk prediction method has the advantages that the high-voltage fault risk of the motor controller can be predicted more accurately by combining the abnormal event data acquired in real time with the important input feature for establishing the high-voltage fault prediction model, so that maintenance personnel can take corresponding maintenance measures before the fault occurs, and the service interruption and the safety problem are avoided.

    本发明公开了一种电机控制器高压故障管理方法及系统,涉及电梯高压故障技术领域,该发明通过结构三维模型和数据采集,实时监测电梯门的异常情况,并采集电机控制器的参数变化,尤其是每日电梯门的异常未完全关闭感应事件次数CJ和每次异常开关门持续时间Ty对门机电机控制器异常变化值的影响,包括第一加速度值sd+、第一减速度值sd‑、第一电流负载值fzz、第一振动值zdz和第一温度值wd的实时监测数据;并作为建立高压故障预测模型的重要输入特征,与实时采集的异常事件数据相结合,有助于更准确地预测电机控制器的高压故障风险,使得维护人员能够在故障发生之前采取相应的维护措施,避免了服务中断和安全问题。
