TEMPERATURE TRANSITION IDENTIFICATION DEVICE, MAINTENANCE PLANNING SYSTEM, AND ELEVATOR SYSTEM

摘要

This temperature transition identification device is provided with, for example, a storage unit (50), a fluctuation calculation unit (51), and a transition identification unit (52). Values measured during elevator diagnostic operation are stored in the storage unit (50). The fluctuation calculation unit (51) removes a long-term fluctuation component from a temporal change of the values stored in the storage unit (50), and calculates a seasonal fluctuation component of the temporal change. The transition identification unit (52) identifies temperature transition in an elevator space on the basis of the seasonal fluctuation component of the temporal change calculated by the fluctuation calculation unit (51) and the real measured value of the temperature in the elevator space.
