Abstract

The application provides a power equipment failure sound image detection system and method. Sound data of detected power equipment are collected through a sound sensor array module, and sent to a dataprocessing module, the sound data include parameter information of sound which is of the detected power equipment and is collected by sound sensors of different positions, and the parameter information includes phase information and amplitude information; the data processing module pre-processes the sound data, and judges whether the parameter information of the sound data after pre-processing meets preset failure parameters, and if yes, the sound data meeting the preset failure parameters are sent to a server; and the server calculates, according to the phase information of the sound collected by the sound sensors of the different positions, phase difference of reaching the sound sensors of the different positions by the sound, determines failure sound source positions of the detected power equipment according to the phase difference, and generates a sound field cloud graph according to the failure sound source positions of the detected power equipment and the amplitude information of the sound.

Description

technical field [0001] The present application relates to the field of power equipment fault detection, and in particular, to an audio-visual detection system and method for power equipment faults. Background technique [0002] Existing power equipment failure sound detection generally relies on power workers to judge whether a failure occurs based on the sound emitted by the power equipment when it is running. However, due to the complex structure of power transmission and transformation equipment, there are many factors that cause equipment failure. The characteristics are often very different. Even if the same fault occurs on the same equipment at different times and places, the fault characteristics are not necessarily the same. Therefore, there will be misjudgments in the manual judgment and it is difficult to find out the specific location where the abnormal sound is emitted. question.
