The setting of the light curtain can prevent the elevator from clamping objects when closing the door, thereby improving the safety of elevator use. After the light curtain is processed, in order to verify its performance, the light curtain function can be tested by testing equipment.

[0003] Prior art 1 (application number CN202222193200.6, Chinese patent published on December 23, 2022) A test device for daily inspection of elevator light curtains, including a device body and a lifting mechanism fixedly connected to the surface of the device body, the lifting mechanism including a rotating assembly; a structural design that promotes movement through a test baffle. When testing the light curtain, in order to improve the sensitivity of the light curtain to scan objects, the operator can turn on the servo motor to test the sensitivity of the light curtain through the movement of the test baffle. The drive of the servo motor is driven by the rotating rod. The movement drives the sliding rod to slide along the inner wall of the second fixed groove. Furthermore, the sliding of the sliding rod drives the rotation of the rotating rod, and the rotation of the rotating rod drives the push rod to slide along the inner wall of the third limit groove, thereby driving the test baffle integrally connected to the push rod to move to one side of the light curtain, so as to realize the control operation of improving the sensitivity of the light curtain when detecting objects; Prior art 2 (application number CN202111451605.9, Chinese patent published on March 11, 2022) An online automatic detection system for an elevator light curtain, including the brake roller and a circular support mechanism.
