Start-up sensor with entrance way monitoring for escalators or moving walkways

A moving device comprising:

• a driven conveyor;
• a control device for controlling the speed of the conveyor;
• a start-up sensor, which monitors a monitoring region in front of the moving device and outputs a start-up signal to the control device upon detecting an object, wherein, upon a provided start-up signal, the control device sets into motion or accelerates the moving device, wherein the start-up sensor is a TOF sensor having (i) a light source for emitting modulated light (ii) a plurality of receiving sensors that are configured as at least one of a line-scan sensor and a matrix sensor for receiving light from the light source that is reflected at the object, wherein the plurality of receiving sensors are arranged with a predetermined spatial relationship with respect to the light source, and (iii) an evaluation electronic system configured for detecting, from the comparison of emitted and received light, the distance of the object from the TOF sensor and the position of the object in the space in front of the moving device.
