S105, optimizing the fault logic according to the comparison result;
specifically, if the characteristic parameter value obviously does not reach the preset threshold value, or only a certain characteristic parameter exceeds the threshold value, the judgment logic needs to be reviewed again, the judgment logic and the threshold value of various elevator fault types are different, similar faults may also be different in elevators of different models, for example, the dimension of door faults is usually door machine current collection, door opening duration, door closing duration and the like, for example, the current value exceeds the preset current (threshold value 1) and exceeds the preset times (threshold value 2), the elevator reports the fault that the door switch is not smooth, but if a maintenance worker finds on site that the reason for causing the overhigh current of the door machine is caused by overweight of an outer door, the current threshold value needs to be set to be a little higher, and the occurrence of false alarm condition is reduced; if the characteristics of the real faults are analyzed, and the characteristics causing the faults are not consistent with the characteristics used in the judgment logic, whether the judgment logic increases or decreases the characteristics is considered, the characteristics of each ladder type or each fault are different, only if the fault is frequently reported by mistake, the characteristics causing the real faults are analyzed according to the real report data of the fault, and whether the logic, the dimensionality or the threshold value of the fault judgment program is reasonable is reversely verified according to the result obtained by machine learning.
