An elevator system (100) comprises an elevator car (101), an elevator controller (117), and a safety controller (121) connected to a plurality of safety devices (126a, 126b, 127, 129, 131, 138a, 138b, 140, 141) arranged to monitor the elevator system. The safety controller is configured to receive a signal in response to a change in state of any of the safety devices and determine a condition of the elevator system in response to a change in state of one or more of the safety devices. If the safety controller makes a determination that the elevator system is in the first condition, the safety controller causes deployment of the elevator brake, preventing movement of the elevator car. If the safety controller makes a determination that the elevator system is in the second condition, the safety controller allows the elevator car to move for a predetermined duration or until the elevator car travels a predetermined distance.
一种电梯系统(100)包括电梯轿厢(101)、电梯控制器(117)和安全控制器(121),安全控制器(121)连接到被布置成监测电梯系统的多个安全装置(126a,126b,127,129,131,138a,138b,140,141)。安全控制器被配置成响应于任何安全装置的状态改变来接收信号,并且响应于安全装置中的一个或多个的状态改变来确定电梯系统的状况。如果安全控制器做出电梯系统处于第一状况的确定,则安全控制器致使部署电梯制动器,防止电梯轿厢移动。如果安全控制器做出电梯系统处于第二状况的确定,则安全控制器允许电梯轿厢移动预定的持续时间或直到电梯轿厢行进了预定距离为止。
