Abstract (en)
The invention provides a method and system for supervising the safety of an elevator having a car (2) driven by driving means (12) within a hoistway (4) wherein a travel parameter (XABS,X"Acc,X'IGB) of the car (2) is sensed and continually compared with a similarly sensed travel parameter (X'IG) of the driving means. If the comparison shows a large deviation between the two parameters, an emergency stop is initiated. Otherwise one of the travel parameters (XABS,X"Acc X'IGB; X'IG) is output as a verified signal (X;X'). The verified signal is then compared with predetermined permitted values. If it lies outside the permitted range then an emergency stop is initiated. <IMAGE>
