Elevator working condition cloud platform data management method based on big data

The invention relates to the technical field of electric digital data processing, in particular to an elevator working condition cloud platform data management method based on big data. Acquiring corresponding serialized data of the door system on each floor when the elevator runs on the same day; the opening duration from opening to closing of the elevator door of each floor of the elevator is collected; the standard opening duration is obtained, the first probability that the opening duration is abnormal is calculated, and the abnormity comprises delayed closing abnormity and advanced closing abnormity; calculating the probability that the early closing abnormity and the delayed closing abnormity are caused by human factors, and correcting the first probability to obtain a second probability; dividing the serialized data into normal data and suspected abnormal data; calculating the abnormal degree of the suspected abnormal data according to the second probability; and obtaining storage time according to the
