The invention discloses a detection method for people trapped in an elevator car. The detection method comprises the steps that an elevator controller (1) of an elevator is set to collect state parameters of the elevator car (3) in real time; setting a digital transmission unit (2) of the elevator to continuously acquire said status parameters from the elevator controller and continuously store the status parameters; when the elevator is in a non-power-off state, the digital transmission unit detects whether the elevator car is in a person trapping state or not according to the logical combination of the obtained state parameters; when the elevator is in a power-off state, the digital transmission unit detects whether the elevator car is in a person trapping state or not according to the logic combination of the state parameters obtained one second before power-off. According to the method, whether passengers exist in the lift car or not is judged through the internal information of the elevator controller, no additional sensor needs to be installed even under the condition of power failure, and the cost can be reduced.

    一种电梯轿厢困人的检测方法,检测方法包括:将电梯的电梯控制器(1)设置成实时采集电梯轿厢(3)的状态参数;将电梯的数字传输单元(2)设置成从电梯控制器持续地获取所述状态参数并且持续地存储状态参数;当电梯处于非断电状态时,数字传输单元根据所获取到的状态参数的逻辑组合来检测电梯轿厢是否处于困人状态;当电梯处于断电状态时,数字传输单元根据在断电前一秒所获取到的状态参数的逻辑组合来检测电梯轿厢是否处于困人状态。该方法通过利用电梯控制器的内部消息判断轿厢内是否有乘客,即使在断电的情况下也不需要安装额外的传感器,可以降低成本。
