The invention relates to the technical field of elevator safety, in particular to an elevator trapped person detection method and system.The elevator trapped person detection method comprises the following steps that data collecting devices are installed on an elevator car and an elevator door correspondingly and used for collecting the elevator running state and the elevator door state; the elevator person recognition device recognizes whether a person exists in the elevator or not; when the three conditions that the elevator is in the static state, the elevator door is closed and people exist in the elevator are met at the same time and the time when the three conditions are met at the same time is larger than a set first threshold value, it is judged that people are trapped in the elevator; when one of the three conditions that the elevator is in the static state, the elevator door is closed and people exist in the elevator is not met or the time when the three conditions are met at the same time is smaller than the set first threshold value, it is judged that people are trapped in the elevator by mistake recognition, and the false detection rate and the missing detection rate of recognition of people trapped in the elevator can be effectively reduced.

    本发明涉及电梯安全技术领域,具体涉及一种电梯困人检测方法及系统,包括如下步骤:在电梯轿厢和电梯门上分别安装数据采集装置,用于采集电梯运行状态和电梯门状态,当电梯为静止状态且电梯门关闭时,电梯识人装置进行电梯内是否有人识别;当电梯为静止状态、电梯门关闭、电梯内有人三个条件同时满足且三个条件同时满足的时间大于设定的第一阈值时,判断为电梯困人;当电梯为静止状态、电梯门关闭、电梯内有人三个条件中有一个条件不满足或三个条件同时满足的时间小于设定的第一阈值,则判断为电梯困人误识别,本发明可有效降低电梯困人识别的误检率和漏检率。
