The invention discloses a multifunctional elevator light curtain protection device. The multifunctional elevator light curtain protection device comprises a light curtain MCU connected with an elevator control system through RS485 communication, and the elevator control system directly reads light curtain data collected by the light curtain MCU so as to judge whether a light curtain is shielded ornot and send out a door opening instruction; and the light curtain controlled by the light curtain MCU is powered by a DC24V power supply in RS485 communication. According to the multifunctional elevator light curtain protection device, a power supply control box of the light curtain can be canceled, the cost and power consumption can be reduced, and the response speed of light curtain protectioncan be improved.
本发明公开了一种多功能电梯光幕保护装置,包括通过RS485通讯与电梯控制系统相连的光幕MCU,电梯控制系统直接读取光幕MCU采集到的光幕数据以判断光幕是否遮挡并发出开门指令;光幕MCU控制的光幕由RS485通讯的DC24V电源供电。本发明可以取消光幕的电源控制盒,不仅可以降低成本和功耗,还可以提高光幕保护的响应速度。
