Title:
PASSENGER CONVEYOR AND CONTROL METHOD OF PASSENGER CONVEYOR
Document Type and Number:
Japanese Patent JP2017095233
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a new passenger conveyor and a control method of the passenger conveyor capable of efficiently evacuating many passengers when a disaster is caused.SOLUTION: When detecting the occurrence of a disaster, an overload determination threshold value SLab for determining an overload state of an electric motor 10 is set as a larger value than a case of normal operation, and the overload state of the electric motor 10 is determined by comparing this largely-set overload determination threshold value SLab and an actual load value. Even when the electric motor becomes the overload state when passengers concentrate on the passenger conveyor by setting the overload determination threshold value larger than the case of the normal operation when the disaster is caused, operation of the passenger conveyor can be continued long until the actual load value reaches this largely-set overload determination threshold value, so that many passengers can be efficiently evacuated.SELECTED DRAWING: Figure 4
