PROBLEM TO BE SOLVED: To provide a vibration abnormality detection device capable of accurately detecting an abnormal state in which a passenger behaves violently, from vibration in an elevator, and provide an elevator control system.SOLUTION: A vibration abnormality detection device (12) comprises a vibration detection part (2) and a calculation processing part (20). The vibration detection part detects vibration of an elevator car (10) in a prescribed direction and generates a detection signal (Az). The calculation processing part performs prescribed calculation processing based on a detection signal. The calculation processing part extracts, from the detection signal, a low frequency component (Aza) in which a frequency component higher than a prescribed first cut-off frequency (f1) is blocked, and a high frequency component (Azb) in which a frequency component lower than a second cut-off frequency (f2) which is equal to or more than the first cut-off frequency is blocked, respectively. The calculation processing part detects an abnormal state of an elevator (1) based on at least any one of the extracted low frequency component and high frequency component.SELECTED DRAWING: Figure 9
【課題】エレベータにおける振動から乗客が暴れている異常状態を精度良く検知することができる振動異常検知装置およびエレベータ制御システムを提供する。【解決手段】振動異常検知装置(12)は、振動検出部(2)と、演算処理部(20)とを備える。振動検出部は、所定方向におけるエレベータかご(10)の振動を検出して検出信号(Az)を生成する。演算処理部は、検出信号に基づいて、所定の演算処理を行う。演算処理部は、検出信号から、所定の第1のカットオフ周波数(f1)よりも高い周波数成分が遮断された低周波成分(Aza)と、第1のカットオフ周波数以上の第2のカットオフ周波数(f2)よりも低い周波数成分が遮断された高周波成分(Azb)とをそれぞれ抽出する。演算処理部は、抽出した低周波成分及び高周波成分のうちの少なくともいずれか一つに基づいて、エレベータ(1)の異常状態を検知する。【選択図】図9
