To provide a safety management system of an elevator capable of improving safety when a maintenance person works on a cage irrespective of whether the elevator can perform communication control.SOLUTION: A safety management system of the present invention comprises an accelerator sensor 1 installed on a cage 4, a measurement processing apparatus 2, and a maintenance terminal 9 maintained by a maintenance person. The accelerator sensor 1 detects acceleration and vibration of the cage 4. The measurement processing apparatus 2 comprises a cage position determining part 51 which receives acceleration information from the acceleration sensor 1, a vibration determining part 52 which receives vibration information from the acceleration sensor 1, a speed determining part 53 which determines whether the cage 4 runs at speed of a specified value or more, and an alert output part 54 which outputs an alert to the maintenance terminal 9 when the cage position determining part 51 detects that the cage 4 stops at the position other than a door zone, the vibration determining part 52 determines that the maintenance person rides on the cage 4, and the speed determining part 53 determines that the cage 4 runs at speed of the specified value or more.SELECTED DRAWING: Figure 7

    【課題】エレベーターが通信制御が可能であるか否かによらず、保守員がかご上で作業するときの安全性を向上できる、エレベーターの安全管理システムを提供する。【解決手段】本発明の安全管理システムは、乗りかご4に設置された加速度センサ1と計測処理装置2と保守員が保持する保守端末9を備える。加速度センサ1は、乗りかご4の加速度と振動を検知する。計測処理装置2は、加速度センサ1から加速度情報を受け取るかご位置判定部51と、加速度センサ1から振動情報を受け取る振動判定部52と、乗りかご4が規定値以上の速度で走行したか否かを判定する速度判定部53と、かご位置判定部51が乗りかご4がドアゾーン以外の位置に止まったことを検出し、振動判定部52が保守員が乗りかご4の上に乗ったと判定し、速度判定部53が乗りかご4が規定値以上の速度で走行したと判定したときに、保守端末9にアラートを出力するアラート出力部54を備える。【選択図】図7
