摘要： An object of the present invention is to provide a sway amount estimation system that can suppress a reduction in user convenience that would occur if the operation method is switched more than necessary. A sway amount estimation system (300) includes a sensing unit (78), a judgment unit (80), and an estimation unit (79). The estimation unit (79) calculates an estimated value of the amount of sway of an elevator rope due to vibration caused by building sway based on the sway sensed by the sensing unit (78) and an estimation model incorporating the effect of the displacement amplification of the displacement amplifier (7). The judgment unit (80) judges if the estimated value calculated by the estimation unit (79) is greater than a threshold for switching the operation method for the elevator apparatus (11).

摘要： Systems, methods and devices for real-time contactless elevator service operation of an elevator includes a trained neural network (TNN) model. The TNN model is trained using a training processor with augmented datasets as a synthetic training dataset, to later perform elevator identifier recognition. The augmented data sets are generated from synthetic text images, the synthetic text images are augmented with different geometrical parameters and visual parameters to a predetermined number of variations in appearance to a set of training elevator identifiers. A camera captures a user image. A text image portion from the user image is extracted using the TNN model, and detects an elevator identifier in the extracted text image portion using the extracted text image portion and the TNN model. The detected elevator identifier is displayed for user confirmation or user cancellation, and upon user confirmation, generates a control command based the detected elevator identifier associated with an elevator service.

摘要： An object of the invention is to provide a vibration damping system that can avoid the occurrence of resonance of an elevator rope regardless of the vibration frequency of a vibration source. A vibration damping system (200) includes a displacement amplifier (7), a calculation unit (66), and a displacement amplification control unit (67). The displacement amplifier (7) is arranged along a given position in the longitudinal direction of the elevator rope. The displacement amplifier (7) amplifies a displacement due to vibration of the elevator rope based on a variable amplification factor. The calculation unit (66) calculates the natural frequency of the elevator rope. The displacement amplification control unit (67) controls the displacement amplification of the displacement amplifier (7) based on the natural frequency calculated by the calculation unit (66) and a preset vibration frequency.
