摘　　要：阐述了基于DSP的鸡蛋破损检测分级装置。设计出以DSP为核心的前端电路,包括声音信号检测与调理、多路选择开关和A/D转换电路以及后端电路,包括驱动和分级执行电路。验证了检测装置的检测与分级性能:好壳蛋判别准确率为93.22%;破损蛋判别准确率为85.61%;系统的总体检测准确率为89.2%。系统完成一枚鸡蛋的检测与分级所需总时间小于1s,系统正常工作时可检测蛋3600枚/h。A testing and grading device of the cracked egg based on DSP was presented. The device consists of front end circuits and trailing end circuit. The front end circuits include detecting and modulating signal circuit, a circuit of threshold trigger and A/D conversion and the interface with digital signal processor （DSP）. The trailing end circuit is a driving circuit for the grading machine. When the system worked steadily, it could detect 3 600 eggs per hour. The detecting accuracy of the system is 93. 22% for intact eggs and 85.61% for the cracked eggs. And the total detecting accuracy is 89.2%.
