For some years now, automatization has become a more important subject in the public transport market, mainly to increase the comfort and the safety of passengers.
The same is valid for automated doors, especially on train platforms. Whereas for exterior doors the safety aspect is generally the most important one, for interior doors comfort is important as well.

Task

On automated interior  train doors, the aim of using sensors is :

1) to open the door when passengers approach the door (detection of motion), by avoiding inappropriate openings in all other situations (for ex. passengers reading papers next to the door : avoid to detect their arms moving).
2) to keep the door open as long as a passenger is next to the door or within its threshold (detection of presence).
3) to avoid that the door will stay open indefinitely, if objects, such as baggage are placed in the sensor’s detection field.

Solution

The sensors belonging to the RS range are dedicated to this kind of application :

• the RS-1 is a 1-spot active infrared sensor designed to open the doors when needed or to keep them open in case of presence at proximity of or in the door’s threshold.
• the RS-15 is an active infrared sensor featuring a detection area (matrix) of 3 x 5 configurable spots, to open the door when needed and  keep it open in case of presence in the threshold.
   

This sensor is the most flexible sensor on the market; the user can chose between 9 available sensing shapes.

Customer benefits

• sophisticated and convenient alternative to push buttons, light barriers or other standard infrared sensors.
• contactless solution.
• RS-15: combined function: opening & presence sensor.
• RS-15: flexible detection area : only 1 sensor for several train platforms needed, so less logistical work.
