Description

Technical Field

[0001] This invention relates to the technical field of edge processing systems, and in particular to an edge processing system for voiceprint data of transformer and reactor operating status. Background Technology

[0002] The acoustic signature signals of power equipment units (transformers and reactors) are often treated as noise and their value ignored. Different fault types in power equipment units (transformers and reactors) affect the vibration state of the transformer, thus generating different acoustic signals. Therefore, acoustic signature acquisition devices can collect continuous acoustic signature signals from power equipment units (transformers and reactors) during operation. Analysis and identification of these acoustic signature signals can enable operational condition detection and diagnosis of power equipment units (transformers and reactors). The general process for determining the operating status of transformers (and reactors) through acoustic signature recognition involves acoustic signature acquisition, uploading to a cloud service unit, and performing acoustic signature comparison and judgment.

[0003] During use, it was found that the power equipment units (transformers and reactors) generate a large amount of acoustic fingerprint data during operation. When the acoustic fingerprint data generated by multiple power equipment units (transformers and reactors) operating simultaneously is all transferred to the cloud server for judgment and identification, there will be a delay in uploading the massive amount of data generated by multiple power equipment units (transformers and reactors) to the cloud server. At the same time, the cloud server unit will also experience a certain delay in analyzing and comparing the massive amount of data, which will cause the best time for transformer fault diagnosis and repair to be missed. In addition, the cloud server unit sends the repair signal to the maintenance personnel, who need to remotely locate the vicinity of the faulty power equipment unit (transformer and reactor), and then manually search for it. After finding it, they can access the cloud service unit to view the faulty power equipment unit. There are also problems such as slow fault search and faults not matching the description.
