Acoustic emission instrumentation is different from the general data acquisition system lies in the hardware real-time acoustic emission parameter extraction. This is because the current ordinary computer and data acquisition peripheral system data through the rate can not meet the acoustic emission signal large data volume waveform data transmission without loss. For example, the maximum sampling speed of 10M, sampling accuracy of 16 bits, the number of channels 8, the waveform data volume of 10M × 2 × 8 = 160MB / s, much larger than the current computer and peripheral theoretical data throughput rate between USB2.0 for 60MB / s (480Mbps), PCI for 132MB / s, thus leading to a large number of data loss. The actual data throughput is much smaller than the theoretical data throughput, the acoustic emission instrument manufacturers claim that the USB2.0 for 40MB / s, PCI for 30MB / s, on the case of the 10M16-bit 8-channel waveform data throughput is only 25% (USB2.0) and 12.5% (PCI). However, many acoustic emission application requirements do not allow any time period of signal loss, such as crack cracking instant signal loss is missed, etc.. This is why the current major acoustic emission instrument manufacturers are in the data acquisition unit of large data volume waveform data for continuous real-time signal processing to extract and convert into a small amount of acoustic emission parameter data and then transmitted to the computer to ensure that any time period of the signal is not lost or less lost. Therefore, the acoustic emission instrument specific (different from the general data acquisition system) important technical indicators for real-time continuous acoustic emission parameters through the rate and acoustic emission parameter analysis and display.
