Door Curtain Sensor

Door curtain sensors play a crucial role in enhancing passenger safety, especially in elevators and public transportation vehicles. These sensors make use of advanced infrared technology and sensor beams to ensure safe operation. Understanding how these systems work can help us appreciate their importance in preventing accidents.

Mechanisms of Door Curtain Sensors

Infrared Technology

Door curtain sensors primarily rely on infrared technology. This involves using infrared light beams that create an invisible shield across the door area. Typically, these systems consist of multiple infrared beams, often between 16 to 32, that span the width of the doorway. When a passenger or an object interrupts these beams, the system detects the obstruction and can automatically trigger the doors to stop or reopen. This non-contact method of detecting obstructions prevents injuries that might occur if the doors closed on a person.

Key Components of Door Curtain Sensors:

  • Infrared Emitters: These transmit infrared light beams across the doorway.
  • Receivers: Positioned opposite to emitters, they detect when the beams are interrupted.
  • Control Unit: It processes signals and directs the door's movement based on whether an obstruction is detected.
  • Mounting Brackets and Interconnection Cables: These ensure the system stays secure and functions correctly.

The combination of these components allows the door curtain sensors to monitor real-time movements, essentially enhancing safety by detecting potential hazards before they can cause harm.

2D Arrays vs. 3D Door Detectors
