摘　　要：预应力管道注浆质量检测是桥梁施工过程中一项十分重要的工作,普通声波仪无法快速、高效地进行无损检测.因此提出一种基于无线数据传输的声波检测系统,该系统采用NRF24L01无线模块结合STM32实现数据的高速无线双向收发,利用LabVIEW设计出智能化的人机交互界面.实验结果证明:该系统响应速度快、同步性好、便携,极大地提高了管道注浆质量检测的效率,具有优良的应用前景.Detection of grouting quality of prestressed pipe is important and arduous in the field of civil engi-neering.Ordinary sonic instrument can not accomplish nondestructive detection fast and efficiently.This pa-per proposes an acoustic detection system based on wireless data transmission,and the system uses NRF24L01 wireless module and STM32 micro-controller to realize high speed wireless bi-directional transmission and re-ception.LabVIEW is used to design the intelligent man-machine interface.The experimental results show that the system has the advantages of fast response,good synchronization and portability,which greatly improves the efficiency of grouting quality detection,and shows a good application prospect.
