摘　　要：该文针对现有禽蛋无损检测方法系统集成度不高,操作界面易用性差,测量误差大、试验效率低等不足,研制了基于Lab Windows/CVI的多传感器融合的禽蛋无损检测虚拟仪器品质分级系统。该系统以Lab Windows/CVI软件为设计操作平台,以MATLAB神经网络的分析算法为分析模块核心,充分结合计算机视觉检测和声学检测方法的优点,在无损检测的信息采集和处理层面实现了多传感器融合。系统通过系统静态分级测试,系统动态分级测试和系统连续动态测试等3种测试,测试结果表明该系统界面易用性好,在快速运行(27个样品/min)的情况下具有较好的准确度(系统连续动态测试准确率大于90%),和漏检率(最高速情况下小于3%)。The system-integration degree, system working efficiency and user interface of egg non-destructive detection system cannot meet the requirement of fast and accurate detection. A non-destructive detection system for eggs based on virtual instrument and artificial neural network was designed and evaluated. This system used Lab Windows/CVI as the system design platform and the neural network as the core-analysis module. This approach fully uses the advantages of both computer vision and acoustics non-destructive detection. This system realizes the amalgamation of multi-sensors in data collecting and processing.. Three kinds of tests were conducted--the system static grading test, the system dynamic grading test and the system continuous dynamic test. The test results indicate this system was easy to use and provided a good graphical user interface. The system has good veracity （system continuous dynamic test result above 90%） and low un-detecting rate at high speed of the gearing machine （27 samples/min）.
