AI Technical Summary

Technical Problem

Existing elevator installations require extensive manual measurement and calculation by technicians to adjust floor offsets, which is time-consuming, prone to errors, and costly, especially in buildings with many floors.

Method used

A system and method utilizing an interactive panel in the elevator car or at the landing floor to input measured floor offsets directly, reducing human intervention and enabling the elevator control unit to calculate and adjust the offsets automatically.

Benefits of technology

The system simplifies the process, reduces errors, and saves time and labor costs by allowing technicians to input measurements without manual calculations, ensuring precise alignment of elevator floors.

Abstract

A system (202) for adjusting floor offset is disclosed. The system (202) comprises an interactive panel (204) operable in a travelling mode or an adjustment interface mode. In the adjustment interface mode, the interactive panel (204) is operated to input a measured value associated with a floor offset at a landing floor (101). The system (202) is configured to switch an operational mode of the interactive panel (204) from the travelling mode to the adjustment interface mode based on the received input. The system (202) is configured to receive the measured value associated with floor offset at the landing floor (101) from the interactive panel (204). The system (202) is configured to determine an updated value associated with a floor level of the landing floor (101) with respect to the elevator car (102) based on the measured value. Further, the system (202) is configured to adjust the floor offset at the landing floor (101) based on the determined updated value.
