Publication number: 20100094798Abstract: Escalator operation sounds are collected by a remote sound-collecting device 15 or fixed sound-collecting devices 17 and 18, and stored in a data collecting device 21 of a diagnosis device 20. A processing device 22 extracts only abnormal sound components of the escalator operation sound by calculation of a difference between reference data and the sound data stored in the data collecting device 21. The processing device 22 determines an occurrence of an anomaly based on whether a maximum peak P of the abnormal sound components is higher than a predetermined threshold value Sh1. When determined that the anomaly has occurred, the processing device 22 investigates a correlation between a frequency analysis result on data around the maximum peak of the abnormal sound components and abnormal sound frequency patterns pre-stored by causes of anomalies, and estimates the cause of the anomaly based on the investigation.Type: ApplicationFiled: July 9, 2009Publication date: April 15, 2010Inventors: Tadashi SHUDO, Masaki Sakurai, Yasuaki Takeda

Patent number: 6971482Abstract: When there is a breakdown in either one of first and second power converters supplying electrical power to a multi-winding motor comprising a wind-up mechanism, a rescue operation can be safely and reliably carried out by using the remaining power converter. A wind-up mechanism comprises a two-winding motor having first and second windings, and, during normal operation, power is supplied to the first and second windings from first and second inverters respectively. When the first inverter has broken down due to excessive current, first and second contactors are switched off, and a third contactor comprising a short-circuiting unit is switched on. Consequently, both windings receive power from the second inverter, enabling the rescue operation to be carried out without causing vibrations.Type: GrantFiled: April 4, 2002Date of Patent: December 6, 2005Assignee: Toshiba Elevator Kabushiki KaishaInventor: Yasuaki Takeda
