An anti-entering protection system used when an elevator door is opened accidentally comprises a forced door opening mechanism installed on a hoistway wall and used for enabling a hoistway door to be completely opened or opened; the blocking device is arranged in front of the hall door, located on the side of the hall door and used for blocking the front of the hall door; 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 car position information in real time, generates a door opening signal and sends the door opening signal to the forced door opening mechanism when the door slot value reaches a set threshold value and the car position information is a non-in-station signal, and further generates a blocking opening signal and sends the blocking signal to the blocking device. According to the elevator, people outside the elevator car are prevented from falling into the hoistway, and meanwhile cognition on potential safety hazards is enhanced.

    一种电梯意外开门时的防进入保护系统,包含:强制开门机构,安装于井道壁上,用于使厅门完全开启或者打开;阻挡装置,设置于厅门前方并位于厅门的侧方,用于挡住厅门前方;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,实时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,生成开门信号并发送至强制开门机构,还生成阻挡开启信号并发送阻挡装置。本发明,防止轿厢外人员掉落至井道,同时,加强对安全隐患的认知。
