1.1 What is Door Clear?
The licensed IRMA MATRIX sensor (release 2) Door Clear feature can, in addition to
passenger counting, detect the presence of persons and objects in the function area.
The sensor uses a status message to indicate whether the door can close without
obstruction. For this purpose, a 3-dimensional monitoring zone is defined within the
sensor´s field of view. The intersection of the sensor´s field of view and the monitoring
zone is called Door Clear zone. If the IRMA MATRIX sensor detects objects or persons in the
Door Clear zone, it sets the status “Door not clear”. Otherwise, it sets the status “Door
clear”.
To check the function area, the “Door clear” sensor status can, for example, be queried by
the on-board computer at any time.
