Portable abnormal diagnosis apparatus, lifter abnormal diagnosis system and method

Abstract

To easily diagnose abnormality such as vibration and noise, while allowing a worker to move to an optional place of a lift. A measuring sensor 13 is connected to the portable abnormality diagnosing apparatus 12, to measure the vibration and the noise in the optional place of the lift. Data measured by the measuring sensor 13 is analyzed on a frequency by a measuring data analyzing part 15. An abnormality diagnosing part 16 diagnoses the existence of abnormality on the basis of this frequency-analyzed data and data stored in a storage part 14, and diagnoses its abnormal place when the abnormality exists. A diagnostic result provided by this abnormality diagnosing part 16 is outputted via a diagnostic result output part 17. Thus, the abnormality such as the vibration and the noise can be easily diagnosed while allowing the worker to move to the optional place of the lift by using the portable abnormality diagnosing apparatus 12.

Description

technical field [0001] The present invention relates to a portable abnormality diagnosis device for diagnosing abnormalities in vibration and noise, used in elevators such as elevators and escalators, an elevator abnormality diagnosis system and an abnormality diagnosis method thereof. Background technique [0002] In general, lifts such as elevators and escalators generate vibration and noise during operation. This kind of vibration and noise will not only bring discomfort to passengers, but also include some major factors of failure in most cases. For this reason, continuing to operate the elevator may be associated with a major failure. [0003] Usually, after the installation of the elevator is completed, its vibration and noise are measured in order to verify whether the installation specification conditions of the elevator are met or not. If it is found that no vibration and noise are generated at this stage, the measurement is usually not carried out thereafter. Th...

AI Technical Summary

Problems solved by technology

[0010] However, when some abnormality occurs, that is, when a large vibration is detected by the acceleration sensor 54, the cause cannot be ascertained only by the detected position of the vibration.

At this time, if the acceleration sensor 54 is installed everywhere in the elevator including the car 53, the cause can be accurately ascertained, but there are problems such as an increase in the price and cost of the elevator as a whole.
