Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, this utility model is described in further detail, but embodiment of the present utility model is not limited to this.
Embodiment 1:
As shown in FIG. 1 to 3, the elevator light curtain inefficacy self-checking unit of the present embodiment includes apparatus for controlling elevator 1, light curtain transmitting terminal 2, light curtain receiving terminal 3, car communication board 4 and light curtain detection switch element 5, described apparatus for controlling elevator 1 is connected with car communication board 4 by CAN communication mode, the X1 end of described car communication board 4 is connected with light curtain receiving terminal 3, and described light curtain detection switch element 5 is connected with the Y1 end of car communication board 4 and light curtain transmitting terminal 2 respectively；Wherein, described light curtain transmitting terminal 2 connects 24V power supply by light curtain detection switch element 5, and described light curtain receiving terminal 3 connects 24V power supply；
Described apparatus for controlling elevator 1, for detecting the state of current elevator, and determines whether light curtain block signal；
Described light curtain transmitting terminal 2 launches light beam to light curtain receiving terminal 3, and whether be used for detecting between elevator cage door has obstacle；
Described car communication board 4, for the order disconnection according to apparatus for controlling elevator 1 or reset light curtain detection switch element 5, and transmission light curtain status signal；
