Infrared Light Curtain elevator door protection system using infrared scanning detection and automatic control technology. Elevator light curtain is a light elevator door safety device for elevators, freight elevators, to protect the safety of passengers. By infrared transmitter and receiver are mounted on both sides of the door of the elevator car, installed in the car roof boxes and special power flex cable four major components.
In the transmitter has 32 months ( 16 months) infrared emission control, in MCU under control, transmitting and receiving tube so opened the car door from top to bottom continuously scans the area, forming a dense curtain of infrared protection. When any beam of light is blocked, the control system immediately open signal output, shut the car door stops and reverses open until passengers or barrier material left after the warning area before the elevator doors closed properly, so as to achieve the purpose of security, so Folders can avoid elevator accidents happen people.
1) has a complete self-test function: When the optoelectronic protective devices or their loss of power failure, ensuring not send wrong signals to the control of electrical appliances.
2) anti-interference ability: the electromagnetic signals, strobe light, welding arc and the surrounding light source has a good anti-jamming capability.
3) Long life: Relay effective output frequency greater than 100 million times, the relay's service life, can be replaced.
4) has a good seismic performance: welded components using SMD technology, and a number of seismic measures.
5) can be set according to user requirements to protect themselves: When the light curtain is blocked, press slide stop running, turn the light again, the press can not run, you must press the reset button, press the slider to start again.
6) connector structure, but not easy to replace
