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 railway vehicles. For exterior doors the safety aspect and the access conditions for persons with disabilities are generally the most important ones.

Task

On automated exterior doors, the aim of using sensors is to safeguard the passengers while  keeping an acceptable level of operability. Therefore, the door should be kept open when somebody tries to enter or to leave the railway vehicle, alone or accompanied (e.g. with. a children or an animal).
The “critical” passengers should be detected without being hit by the door. Therefore, additional sensor solutions to contact edges used nowadays are requested.

Solution

Our LZR® platform, which is based on the time-of-flight technology, offers the possibility to set up such a solution, the LZR®-RS300.
The LZR®-RS300 has been designed to safeguard exterior railway doors in either 2 or (optionally) 3 dimensions.
One single sensor (emission and receiver are integrated in one housing) can be enough to safeguard a complete door, either single or double leaf,  flat or curved.

Customer benefits

• sophisticated and convenient alternative to light grids.
• emission and receiver integrated in one housing so,less effort for integration.
• complete coverage of the door surface.
• in combination with contact edges, the LZR®-RS300 probably provides the highest degree of safety on exterior train doors.
