Embodiment Construction

[0024] The technical solutions of the present invention will be described in detail below with reference to the accompanying drawings, but the protection scope of the present invention is not limited to the embodiments.

[0025] Such as figure 1 The structural damage detection system based on voiceprint recognition shown is composed of a primary audio anomaly detection module, a damage feature classification detection module, a damage feature review module, and an alarm module. The input signal is the continuous sound signal collected by the on-site percussion detection, and the on-site percussion detection also undertakes the function of reviewing the damage characteristics.

[0026] Firstly, the continuous sound signal collected by the on-site knocking detection module is imported into the primary audio anomaly detection module according to the detected time series, and the voiceprint characteristics such as wavelength, intensity, attenuation characteristics, and sound wave ...

Abstract

The invention discloses a structural damage detection system and method based on voiceprint recognition. An on-site knocking detection module is used for detecting an on-site structure and obtaining continuous sound signals; a primary audio anomaly detection module is used for receiving input of continuous sound signals and outputting feature vectors formed by various voiceprint features to the damage feature classification detection module; a damage feature classification detection module outputs an undetermined damage category of the internal damage through a machine learning classification algorithm; a damage feature re-checking module feeds back an undetermined damage category to the field knocking detection module, and a field knocking detection module adjusts the knocking detection frequency and intensity according to preset damage voiceprint features and outputs the re-checked damage category to an alarm module; the alarm module records the damage type and the damage occurrence position. According to the system, dependence on experience and technology of detection personnel is reduced, operation is more visual, and the result is more accurate.

Description

technical field [0001] The invention relates to the technical field of structural damage detection, in particular to a structural damage detection system and method based on voiceprint recognition. Background technique [0002] Nondestructive testing methods such as ultrasonic rebound, acoustic emission testing, X-ray projection, and infrared scanning are commonly used in engineering applications in order to achieve the purpose of detecting structural damage. However, the current status of engineering applications in developed countries such as the United States and Japan shows that the current nondestructive testing technology is far from meeting the requirements of practical engineering applications. At the same time, it is necessary to quickly judge the damage type, location, and degree after collecting signals on site. The main reason is that due to the high price of testing equipment and different working principles and performances, especially for the rapid detection ...
