摘　　要：为实现电动扳手零件缺损的出厂检测,设计了一套自动声学采集系统,采集电动扳手运行时的声音信号,为计算机检测提供数据支持。系统由下位机和上位机组成,上位机采用LabVIEW编程,通过USB接口控制下位机工作,采用声卡采集麦克风输出信号;下位机采用STM32控制推杆,实现电动扳手的自动启停操作。经测试,系统可自动采集电动扳手工作声音,提升零件缺损检测效率。The automatic acoustic acquisition system was design to collect the running acoustic signal for testing the electric impact drills before leaving the factory.The system was proposed in this paper includes two parts:the upper system and the lower system.The upper system controls the lower system by USB and collects the running acoustic signal by sound card,which is programed by LabVIEW.The lower system uses the STM32 to control the auto-start and auto-stop operation of electric impact drills by the linear actuator.By the test,the system can automatic collect the acoustic signal and increase the fault diagnosis efficiency of electric impact drills.
