Rope inspection system, inspection device, and rope inspection method

Abstract

To simplify the process of checking for abnormalities such as broken strands in ropes, thereby reducing false detections and missed detections. [Solution] A rope inspection system for inspecting the ropes that raise and lower an elevator car, comprising: an imaging device capable of imaging the rope; a control device for raising and lowering the elevator car; and an inspection device for determining abnormalities in the rope based on images captured by the imaging device. The system further comprises: a control unit for raising and lowering the elevator car and sending imaging instructions to the imaging device during the movement; and a first communication unit for transmitting images captured by the imaging device to the inspection device. The inspection device includes: a storage unit for storing a determination model, which is a learned model that takes the captured images of the rope as input and outputs whether or not there is an abnormality and the abnormal state; a second communication unit for receiving the captured images from the control device; an abnormality determination unit for determining whether or not there is an abnormality in the rope and the abnormal state using the determination model from the received captured images; and a notification unit for notifying when an abnormality is determined to be present in the rope.
