A safety system of an escalator according to an embodiment includes a long object determination unit, a rise rate acquisition unit, a rise rate determination unit, and a brake control unit. The long object determination unit determines whether a passenger entering the passenger conveyor holds a long object. The increase rate acquisition unit acquires a motor current increase rate of a drive motor that moves a step cycle. When the motor current value of the drive motor reaches a predetermined overload current value, the increase rate determination unit determines whether or not the motor current increase rate when the motor current value reaches the overload current value is equal to or greater than a reference increase rate. When the brake control part determines that the motor current rise rate is greater than the reference rise rate, the brake control part enables the brake to act so as to stop the circulation movement of the steps.

    实施方式的自动扶梯的安全系统具备长条物判定部、上升率取得部、上升率判定部、及制动器控制部。长条物判定部判定乘入乘客输送机的乘客是否持有长条物。上升率取得部取得使梯级循环移动的驱动马达的马达电流上升率。上升率判定部在驱动马达的马达电流值达到规定的过载电流值的情况下,判定马达电流值达到过载电流值时的马达电流上升率是否为基准上升率以上。制动器控制部在判定为马达电流上升率为基准上升率以上的情况下,使制动器动作而使梯级的循环移动停止。
