The invention discloses an elevator ranging method. The elevator ranging method comprises the steps that when a light curtain system of an elevator operates, the number of infrared effective receivinglamps receiving transmitting signals of an infrared ranging transmitting lamp at a preset transmitting angle of the infrared ranging transmitting lamp is obtained in real time; a signal receiving range of the infrared effective receiving lamps is calculated according to the number of the infrared effective receiving lamps; and the door opening distance of the elevator is calculated according to the preset transmitting angle of the infrared ranging transmitting lamp and the signal receiving range. The invention further discloses an elevator ranging device, elevator ranging equipment and an elevator ranging system. By adopting the embodiment of the invention, the current door opening distance of the elevator can be accurately obtained, and the situation that a light curtain of the elevatoris abnormal or unavailable is avoided.
本发明公开了一种电梯测距方法,包括:当电梯的光幕系统运行时,实时获取在红外测距发射灯的预设发射角度下接收到所述红外测距发射灯的发射信号的红外有效接收灯的个数;通过所述红外有效接收灯的个数计算所述红外有效接收灯的信号接收范围;根据所述红外测距发射灯的预设发射角度和所述信号接收范围计算电梯的开门距离。本发明还公开一种电梯测距装置、一种电梯测距设备和一种电梯测距系统。采用本发明实施例,能够精确得出电梯当前的开门距离,避免出现电梯光幕异常或不可使用的情况。
