Equipment for monitoring the space in front of escalators and moving walkways by high-frequency sensors

摘要

Sensing equipment for monitoring the space in front of escalators for the control of the drive has sensors arranged in handrail inlet caps of the escalator balustrades. Each sensor consists of a transmitter and a receiver and operates with high-frequency waves. The sensors monitor the access to the escalator in a specific region in front of the entry to the escalator, for example the region of the entrance plate. On entry into the monitoring region of a sensor the high-frequency waves emitted by the transmitter are reflected by the person or object and picked up by the associated receiver and the escalator drive is switched on.
