Embodiment Construction
[0018] Such as figure 1 As shown, the present invention provides a vibroacoustic defect detection method and identification method for porcelain post insulators based on a normal single-class integrated model, which specifically includes the following steps:
[0019] The first step is to collect data and construct a data set of normal state of porcelain post insulators.
[0020] Porcelain post insulator normal state data set, contains the following fields
[0021] The model of the Field 1 porcelain post insulator corresponds to the specific manufacturer and model of a specific porcelain post insulator.
[0022] Field 2 Excitation Rod Hitting Position, where the excitation rod of the percussion device is placed.
[0023] Field 3 receiving rod listening position, where the receiving rod of the percussion device is placed.
[0024] Field 4 is a set of acoustic wave sampling data in normal state, which corresponds to the acoustic wave data of the porcelain post insulator in nor...
