Problems solved by technology

As far as concrete materials are concerned, the processing method of acoustic emission data does not consider the influence of concrete's own structural factors on the basic performance of acoustic emission, so it cannot handle the signals related to concrete corrosion damage well.
The signal data of concrete corrosion damage collected by the sensor cannot be directly used for the analysis of the experimental results, but the secondary processing of the signal data is required, and the workload is huge

Embodiment Construction

[0025] Such as Figure 1 to Figure 4 As shown, a concrete corrosion acoustic emission signal data analysis and processing system includes:

[0026] The acoustic emission signal acquisition instrument 1 is used for acquiring acoustic emission signal data.

[0027] computer, the computer is installed with a software platform 2 based on matlab, and the software platform 2 based on matlab is used for analyzing and processing the acoustic emission signal data.

[0028] With the help of the powerful data processing capability and graphic display function of the matlab platform, the software can clearly express the calculation results. In order to ensure that the collected waveform is not distorted, the sampling frequency of the acoustic emission sensor is 10-50MHz, and the amount of acoustic emission signal data collected per minute is usually between 6×107 and 3×108, and only one power-on in the concrete dry-wet cycle It takes 2 to 3 minutes to accelerate the corrosion process. S...
