| 摘要 |
The invention relates to a method and a device for monitoring the motion of an elevator cab. An acceleration (AS) of the elevator cab and a travel velocity (VM) or a travel path length (SM) of the elevator cab are measured and an integrated travel velocity (VS) is calculated from the measured acceleration (AS). Here, the measured travel velocity (VM) or the travel velocity (VM) derived from the measured travel path length (SM) is used as a starting value of an integration cycle. Furthermore, the integrated travel velocity (VS) is compared with at least one specified limit velocity (VG) and a safety measure (27) is initiated if it is determined that the specified limit velocity (VG) is exceeded. |
