The invention discloses an elevator light curtain device which comprises a transmitting end, a receiving end, a connecting line and a power supply box. The power supply box is connected with the transmitting end and the receiving end through the connecting line. Wherein the transmitting end comprises an infrared (or visible light, only infrared is taken as an example below) LED lamp strip, and a plurality of infrared light-emitting nodes are arranged on the LED lamp strip from top to bottom; the receiving end comprises a camera sensor and is used for identifying the number of light-emitting nodes in the current real-time received light-emitting node image, comparing the number of the light-emitting nodes with the total number of the light-emitting nodes of the LED lamp strip, and if the camera sensor detects that the number of the light-emitting nodes in the real-time received light-emitting node image is smaller than the total number of the light-emitting nodes of the LED lamp strip, sending the light-emitting nodes to the receiving end. If yes, it is judged that one or more light-emitting nodes are shielded in the view field of the current camera sensor, finally it is judged that there is a shielding object, or the light-emitting nodes break down, it is safe for elevator passengers, and it can also be judged that there is a shielding object; the elevator light curtain device provided by the invention has better use performance and detection precision, and is low in cost.
本发明公开了一种电梯光幕装置,包括发射端、接收端、连接线和电源盒:所述电源盒通过连接线分别与发射端、所述接收端连接;其中,所述发射端包括红外(或可见光,以下仅以红外为例)LED灯带,所述LED灯带自上而下排列了多个红外发光节点;所述接收端包括摄像传感器,用于识别当前实时接收发光节点图像中的发光节点数量,并与LED灯带的总发光节点数量对比,如果摄像传感器检测发现实时接收发光节点图像中的发光节点数量少于LED灯带的总发光节点数量,则判断当前摄像传感器视野内存在一个或多个发光节点被遮挡,最终判定为有遮挡物,或发光节点本身出现故障,为电梯乘客安全,也可判定为有遮挡物;本发明提供的电梯光幕装置具有更好的使用性能和检测精度,且成本不高。
