Elevator light curtain is a kind of light-based elevator door safety protection device, which is suitable for passenger elevators and freight elevators to protect the safety of passengers. It is composed of four parts: infrared transmitter and receiver installed on both sides of the elevator car door, power box installed on the roof of the car and special flexible cable. There are 32 (16) infrared transmitting tubes in the transmitter, and under the control of the MCU, the transmitting and receiving tubes open in turn, continuously scanning the car door area from top to bottom, forming a dense infrared protective light curtain. When any of the lights is blocked, the control system immediately outputs the door opening signal, the car door stops closing and reverses to open, until the passengers or obstructions leave the warning area after the elevator door can be closed normally, so as to achieve the purpose of safety protection, so as to avoid the occurrence of elevator clamping accidents.
