Title:
ELEVATOR CONTROL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/144985
Kind Code:
A1
Abstract:
Provided is an elevator control system that can suppress the effects of car displacement, even when the length of a detection tape changes over time. A control system (8) has a detection tape (9) that is arranged on a hoistway (3) so as to have a fixed end (14) and a mobile end (15) in the vertical direction. A reading device (10) that is provided to a car (7) reads information on the detection tape (9) that indicates a position in the longitudinal direction. A detection device (11) detects that the car (7) is at a reference position that is on the mobile end (15) side of the hoistway (3) as a result of a detection switch (17) that is provided at the reference position detecting a detection target cam (16) that is provided to the car (7). A control device (13) performs control processing that treats the position read by the reading device (10) as the absolute position of the car (7). The control device (13) corrects the absolute position of the car (7) using the position in the longitudinal direction read by the reading device (10) at the time of detection by the detection device (11).
