Document Type and Number:
Japanese Patent JP2015124038
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a display device of an elevator that can predict a state of deterioration due to secular change of a car connecting instrument provided in a car of the elevator and display prediction data about the deterioration.SOLUTION: The display device of an elevator comprises: a power measurement device 14 that measures values relating to electrical states of car connecting instruments 21, 22 and 25 provided in a car 7 of the elevator; and an elevator control panel 12 that memorizes the values relating to the electrical states when shipping the car connecting instruments 21, 22 and 25 as initial parameters, calculates prediction data about deterioration due to secular change of the electrical states of the car connecting instruments 21, 22 and 25 by regression analysis using the measured values of the car connecting instruments 21, 22 and 25 measured by the power measurement device 14 and the initial parameters, and displays the prediction data about the deterioration on a car indicator 24 provided in the car 7.
