State Estimation Device For Cord Like Body Of Elevator And Elevator System
Abstract: Provided are: a state estimation device that can stably estimate the amplitude of an antinode even at a vibrational node of a cord-like body of an elevator; and an elevator system. This state estimation device (21) of an elevator system (1) is provided with a pair of contact bodies (22), a contact sensing unit (23), and an amplitude estimation unit (24). The pair of contact bodies (22) are disposed along nodes of fundamental vibration of a cord-like body of an elevator at positions mutually symmetrical with respect to the cord-like body. The contact sensing unit (23) senses contact of a node with at least one of the pair of the contact bodies (22). The amplitude estimation unit (24) estimates the amplitude of an antinode of fundamental vibration of the cord-like body on the basis of at least two types of time, among the start times and the end times of contact with each of the pair of contact bodies (22).
