Automatic Selective Door Operating system (ASDO)

Automatic Selective Door Operating system (ASDO)

Automatic Selective Door Operating system (ASDO)
The ASDO technology gives you the ability to open different train doors at each station to maximize safety and customer comfort.
THE BENEFITS OF USING ASDO

ASDO stands for Automatic Selective Door Operation or Operating system. ASDO was primarily developed to improve passenger operation at stations where the platforms are shorter than the trains. Without ASDO, trainsets with one or several doors not facing the platform would commonly remain shut (B in illustration), forcing passengers to board or leave the trains through other trainsets.

In the illustration below, one can see that ASDO enables two more doors to open (C), facilitating passenger movements between the platform and the train. ASDO improves passenger comfort and safety while allowing for shorter stops at stations.


SAFE DOOR OPENING DETECTION

The ASDO system first checks the platform configuration to ensure doors will only be opened at the right places.

Sensors are usually positioned on the tracks as well as in the train to enable detection of safe door openings. Other systems rely on GPS positioning of the train, thus identifying the station, to determine how many doors shall be opened and on what side(s) of the train.


SAFETY INTEGRITY LEVEL (SIL)

ASDO is a safety critical function commonly developed as SIL-2, providing probabilistic risk reduction factor from 10-6 to 10-7.

SIL stands for Safety Integrity Level and is a concept defined in the IEC 61508 standard. For the rail industry, the CENELEC has developed the EN 50126, EN 50128 and EN 50129 standards. For more information on SIL, please visit our SIL page here.
