Design of Multi-channel Acoustic Signals Acquisition System Based on FPGA and TF Memory Card

摘要：

aiming at the inherent limitation of high frequency acoustic signals acquisition real-time,a design of multi-channel acoustic signals acquisition and storage system is proposed in this paper,in which singlechip acts as control cell,tf memory card as the memory device and fpga as the high-speed interface of data buffering and format conversion,fat file system is built in tf memory card and acquisition data store as files,this design has advantages such as small size,easy installation,high-speed and real-time storage,good universality and low power consumption,it has been successfully applied in a radiated noise acquisition system of high-speed underwater vehicle and could be very useful for many other areas.
