Detection system and method for sound abnormality of power equipment

Abstract

A sound abnormality detection system for power device comprises an audio detection subsystem and a computer subsystem wirelessly communicated with the audio detection subsystem. The audio detection subsystem comprises an audio collection module, a video service module, an audio training and identification module, a storage module, and a first communication module. The audio collection module is connected with the video service module, the audio training and identification module and the first communication module in turn. The storage module is connected with the audio training and identification module bidirectionally. The computer subsystem comprises a host machine, an audio data display module, an alarm module, and a second communication module. The host machine is connected with the audio data display module, the alarm module, and the second communication module respectively. The detection system is flexible, low cost and highly reliable.

Description

technical field [0001] The invention relates to a sound abnormality detection system and method, in particular to a sound abnormality detection system and detection method for power equipment. Background technique [0002] At present, the normal operation of substations mainly depends on manual on-site inspection and maintenance. This method has the following two problems: 1. The safety of the inspectors. The substation is a dangerous environment full of high voltage and discharge, which is easy to cause physical injury to the inspectors. 2. The effect of manual inspections. In the face of repetitive mechanical work, it is easy to cause fatigue and slackness, which reduces the effect and quality of inspections. Moreover, manual inspections cannot meet the suddenness and timeliness of substation equipment failures. Therefore, the effect of manual inspection is unstable, and the reliability cannot be improved. [0003] Some substations have begun to try automation and intell...

Problems solved by technology

This method has the following two problems: 1. The safety of the inspectors. The substation is a dangerous environment full of high voltage and discharge, which is easy to cause physical injury to the inspectors. 2. The effect of manual inspections. In the face of repetitive mechanical work, it is easy to cause fatigue and slackness, which reduces the effect and quality of inspections, and manual inspections cannot meet the suddenness and timeliness of substation equipment failures

Its shortcomings have the following two aspects: 1. The fixed point and the way of being close to the body make the arrangement position of the audio sensor fixed and inflexible; 2. Each substation equipment needs to be equipped with an independent audio sensor, too many Advanced sensor equipment, resulting in difficult layout and high cost

Ultrasonic testing method has the defects of high cost and inability to detect continuously in real time
