Equipment fault identification method

Abstract

The invention discloses a device fault identification method, comprising: collecting the acceleration data of the set direction during the operation of the device setting part; capturing the complete acceleration data signal of the device running once; and performing the complete acceleration data signal of the device running once Transform to obtain the detail factor of the signal; reconstruct the obtained detail factor to obtain the acceleration data with practical significance, and at the same time obtain the five-dimensional data of the running signal; according to the characteristics of the reconstructed acceleration data and the five-dimensional data , to confirm the running status of the elevator by identifying the equipment, if there is a sudden change, record the sudden change amplitude, location and other information, and analyze it according to the sudden change fault and fault model. If the in-depth analysis does not find a sudden change, it will handle the non-mutant fault category, conduct a comparative analysis according to the corresponding fault model, and give the fault probability, cause, and maintenance suggestions. The present invention can obtain equipment status in real time, and determine equipment problems according to related features.

Description

technical field [0001] The invention belongs to the technical field of equipment fault detection and relates to a method for identifying equipment faults. Background technique [0002] According to national statistics, based on the analysis of demand in traditional real estate, rail transit, upgrading and other fields, it is expected that domestic elevator sales will continue to increase in 2020. From 2013 to 2017, the number of domestic elevators has soared from 3 million to nearly 6 million. At the same time, the completed area of ​​domestic real estate is also steadily increasing. [0003] While the number and development prospects of domestic elevators are soaring, elevators lack effective technical means for safety supervision and only rely on maintenance personnel for regular inspection and maintenance. However, with the rapid increase in the number of elevators in recent years, the maintenance personnel remain unchanged. It is becoming more and more difficult to ensu...

AI Technical Summary

Problems solved by technology

However, with the rapid increase in the number of elevators in recent years, the maintenance personnel remain unchanged. It is becoming more and more difficult to ensure timely elevator maintenance and maintenance. Moreover, the structure of the elevator is complex, and when a problem occurs, it cannot be accurately located, and the investigation will be a lot of waste. Time is reduced, efficiency is reduced, and it will also affect the subsequent elevator maintenance work of maintenance personnel

[0004] In reality, elevator failures are often found only when passengers are trapped, resulting in property losses and casualties caused by untimely discovery and untimely rescue. Therefore, it is more important to develop a system that can independently identify and judge elevator failures. Through After the machine is identified, it can directly prescribe the right medicine, reduce time consumption, and improve elevator safety and user experience in a timely manner
