Abstract
A method and an equipment for monitoring the movement of an elevator car detect an acceleration of the elevator car and a travel speed or a travel distance of the elevator car and an integrated travel speed is calculated from the detected acceleration. In that case, the detected travel speed or the travel speed derived from the detected travel distance is used as a start variable of an integration cycle. In addition, the integrated travel speed is compared with at least one predetermined limit speed and a safety measure is triggered if exceeding of the predetermined limit speed is established.
