Estimating the term…
The invention relates to a method for measuring the braking distance and to a braking distance measuring device for carrying out the method on an escalator or a moving walkway. The braking distance measuring device has at least one trigger device which can be connected to the controller of the escalator or the moving walkway, an optically detectable linear measuring scale, an optical sensor, and an acoustic sensor. In order to allow a more precise measurement of the braking distance, a braking process is optically and acoustically recorded as an image sequence with a graphically displayed audio track. The start point and the end position of braking operation noises recorded on the audio track can be precisely assigned to the images of the image sequence, and the braking distance is ascertained from the determined images by comparing the different positions of a marking with the measuring scale.
