A forced door closing system for accidental door opening of an elevator comprises a first detection element, a second detection element, a controller and a door closing mechanism. The first detection element detects the size of a door slot in real time and generates a door slot value; the second detection element is used for detecting the elevator arrival condition in real time and generating lift car position information according to the elevator arrival condition, and the lift car position information is a non-in-station signal when the elevator does not arrive at the station and is an in-station signal when the elevator arrives at the station; the controller is electrically connected with the first detection element and the second detection element, obtains a door slot value and lift car position information, generates a door closing signal when the door slot value reaches a set threshold value and the lift car position information is a non-in-station signal, and sends the door closing signal to the door closing mechanism; and the door closing mechanism is used for closing the elevator landing door. By means of the elevator landing door, the problems that after the elevator landing door is accidentally opened, people fall down, and an elevator structure in a hoistway is prone to being damaged due to the fact that objects are lost are better solved.
一种电梯意外开门时的强制关门系统,包含检测元件一、检测元件二、控制器、关门机构;检测元件一,实时检测门缝大小并生成门缝值;检测元件二,实时检测电梯到站情况,根据到站情况生成轿厢位置信息,轿厢位置信息在电梯未到站时为未在站信号,在电梯到站时为在站信号;控制器,和所述检测元件一以及检测元件二相电连接,获取门缝值以及轿厢位置信息,在门缝值达到设定阀值且轿厢位置信息为未在站信号时生成关门信号,并发送至关门机构;关门机构,用以使电梯厅门关闭。本发明,更好地解决了电梯厅门意外开门后的人员坠落问题以及井道中的电梯结构易被丢东西而破坏的问题。
