There is provided an emergency terminal stopping system for an elevator system, the emergency terminal stopping system comprising: a sensor configured to determine data related to the motion of an elevator car moving within an elevator hoistway; at least one elevator brake configured to halt the motion of the elevator car; at least one elevator safety gear device provided on the elevator car; and at least one buffer provided at a lower portion of the hoistway. The controller is configured to receive data from the sensor relating to the motion of the elevator car; monitor a current speed of the elevator car with respect to a distance from a terminal limit of normal elevator car travel; detect an abnormal speed of the elevator car; activate the at least one elevator brake in response to a detected abnormal speed; monitor a current acceleration of the elevator car following activation of the main elevator brake; detect an abnormal acceleration of the elevator car; and activate the elevator safety gear device in response to a detected abnormal acceleration.
提供有一种用于电梯系统的紧急终端停止系统,该紧急终端停止系统包括:传感器,其配置成确定与在电梯井道内移动的电梯轿厢的运动有关的数据;至少一个电梯制动器,其配置成使电梯轿厢的运动暂停;至少一个电梯安全钳装置,其设于电梯轿厢上;以及至少一个缓冲器,其设于井道的下部部分处。控制器配置成:从传感器接收与电梯轿厢的运动有关的数据;关于距正常电梯轿厢行进的终端极限的距离监测电梯轿厢的当前速率;检测电梯轿厢的异常速率;响应于所检测的异常速率而激活至少一个电梯制动器;继激活主电梯制动器之后,监测电梯轿厢的当前加速度;检测电梯轿厢的异常加速度;以及响应于所检测的异常加速度而激活电梯安全钳装置。
