Motor controller high-voltage fault management method and system

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
