An elevator safety monitoring system, an elevator system (100), an elevator drive unit (35), and a method for operating an elevator are presented. The elevator safety monitoring system comprises an elevator car absolute position and speed feedback device (60), a safety monitor (40) connected to the absolute position and speed feedback device (60), and a safety zone (104) extending inside an elevator shaft (12). The safety zone (104) is associated with an allowable maximum speed (412) of an elevator car (10), wherein the allowable maximum speed (412) is lower than a rated speed (411) of an elevator car (10) outside the safety zone (104), wherein the safety monitor (40) is configured to determine a slowdown failure of the elevator car (10) approaching the safety zone (104), and, upon the determination of the slowdown failure, command an actuator to decelerate the elevator car (10) to the allowable maximum speed (412).
提供了一种电梯安全监控系统、电梯系统(100)、电梯驱动单元(35)以及操作电梯的方法。电梯安全监控系统包括电梯轿厢绝对位置和速度反馈装置(60)、连接到绝对位置和速度反馈装置(60)的安全监控器(40)以及在电梯井道(12)内延伸的安全区域(104)。安全区域(104)与电梯轿厢(10)的允许的最大速度(412)相关联,其中,允许的最大速度(412)低于安全区域(104)外部的电梯轿厢(10)的额定速度(411),其中,安全监控器(40)被配置为确定接近安全区域(104)的电梯轿厢(10)的减速故障,并且在确定减速故障时,命令致动器以使电梯轿厢(10)减速至允许的最大速度(412)。
