The invention relates to a scanning control method and system for an elevator intelligent light curtain, and belongs to the technical field of elevators. Acquiring a real-time distance between the transmitting end and the receiving end of the light curtain, and comparing the real-time distance with a preset distance threshold to determine a distance interval; controlling the scanning mode of the light curtain according to the interval; wherein the distance intervals comprise a first distance interval, a second distance interval and a third distance interval, and the scanning modes comprise a first scanning mode, a second scanning mode and a third scanning mode; when the real-time distance is in a first distance interval, controlling the light curtain to scan in a first scanning mode; when the real-time distance is in a second distance interval, controlling the light curtain to scan in a second scanning mode; when the real-time distance is in a third distance interval, the light curtain is controlled to scan in a third scanning mode, the first scanning mode is parallel scanning, and the second scanning mode and the third scanning mode both comprise parallel scanning and offset scanning. According to the invention, the omission ratio and the misjudgment rate during light curtain detection are reduced.

    本发明涉及一种电梯智能光幕的扫描控制方法及系统,属于电梯技术领域。采集光幕发射端和接收端间的实时距离,与预设距离阈值比较确定其所在距离区间;根据区间控制光幕的扫描方式;其中,距离区间包括第一距离区间、第二距离区间和第三距离区间,扫描方式包括第一种扫描方式、第二种扫描方式和第三种扫描方式;当实时距离在第一距离区间时,控制光幕以第一种扫描方式扫描;当实时距离在第二距离区间时,控制光幕以第二种扫描方式扫描;当实时距离在第三距离区间时,控制光幕以第三种扫描方式扫描,且第一种扫描方式为平行扫描,第二种扫描方式和第三种扫描方式均包括平行扫描和偏移扫描。本发明降低了光幕检测时的漏检率和误判率。
