集成化寻址超声传感器阵列接收电路设计及应用
Design and application of integrated receiving circuit for addressing ultrasonic transducer array
摘要
Abstract
The addressing ultrasonic transducer array enables flexible selection of transmitting and receiving el-ements,but achieving full functionality requires dedicated circuit.In response to the current lack of dedicated receiving circuits for such arrays,an integrated circuit design scheme for a 64-element addressing ultrasonic transducer array is proposed,which facilitates flexible element gating while reducing system complexity and size.An 8-channel integrated analog front-end chip circuit is used to implement a row-unit gated receiving mechanism for an 8+8 addressing ultrasonic transducer array.The reception circuit system employs a field pro-grammable gate array(FPGA)to control the timing of element gating and manage data transmission,thereby enhancing the precision of timing control as well as the real-time performance and accuracy of data transmis-sion.An addressing excitation circuit and an integrated reception circuit system are fabricated.The 8+8 ad-dressing ultrasonic transducer array is used to inspect hole-type defects in an aluminum test block,and the de-fect imaging performance is analyzed using the total focusing method.The experimental results show that un-der the single element,row element,and column element transmitting/receiving modes,the echo signal-to-noise ratios for detecting a ϕ4mm through-hole defect are 19.77,21.45,and 21.28 dB,respectively.The relative errors in defect depth estimation are 0.61%,1.17%,and 1.83%,respectively.After artifact suppres-sion,the performance parameters of the defect image array are 0.403 1,0.286 5,and 0.370 9,respectively.关键词
