A nondestructive testing hardware system for eggshells based on DSP was established. The system had multiple functions,such as controlling knock device,sampling and processing acoustic signal emitted by eggs,communicating with PC and so on.

• 设计了一种基于DSP的蛋壳无损检测硬件系统,该硬件系统具有控制敲蛋装置、声音信号采集与处理、破损识别和与PC机通信等功能。
