The invention relates to the technical field of elevator light curtains, in particular to a method for identifying transparent, semitransparent and small-size objects and an elevator light curtain. A plurality of first transmitting tubes and a plurality of first receiving tubes are arranged at the TX end of the light curtain, a plurality of second receiving tubes are arranged at the RX end of the light curtain, the first transmitting tubes and the first receiving tubes are installed on the same side, infrared rays of reflection and diffuse reflection are utilized, small-size, transparent and semitransparent objects which are not easy to detect are easy to detect, and the detection accuracy is improved. According to the elevator light curtain, through data collection and analysis of a laboratory, the characteristics of common interference information are analyzed, multiple judgment requirements such as the difference value of voltage values, the variation amplitude of the voltage values and the difference of voltage average values under the corresponding distance of detected voltage values are applied, interference signals are eliminated, and the accuracy of the elevator light curtain is improved. Transparent, semitransparent and small-size objects can be accurately judged, and the safety of elevator operation is improved.
本发明涉及电梯光幕技术领域,具体涉及一种识别透明、半透明、小体积物体的方法及电梯光幕。所述光幕TX端设置有若干第一发射管和若干第一接收管,所述光幕RX端设置有若干第二接收管,本发明通过在同侧安装第一发射管与第一接收管,利用反射与漫反射的红外线,使不易检测的小体积、透明、半透明物体易于检出,提高了电梯光幕的功能性,本发明通过实验室的数据采集和分析,分析处将常见干扰信息的特征,运用多种通过多个判断要求,如电压值的差值、电压值的变化幅度、检测电压检测值对应距离下电压平均值的差距等,排除干扰信号,能够精准判断出透明、半透明、小体积物体,提高电梯运行的安全性。
