Starting sensor with entrance monitoring for escalators or moving walkways

摘要

The driving device has a control unit that sets and accelerates the motion of the drive portion with the start-up signal from a time-of-flight (TOF) sensor (7). A receiving sensor is arranged in a predetermined spatial relation to a light source to receive the light reflected on the object from the light source. An electronic evaluation unit is provided to detect the distance of the object from sensor and the position of the object in the space in front of the drive portion, from the comparison of emitted and received light.
