针对无损检测领域对采集设备低功耗、小型化的要求,在分析现有采集设备的劣势后,基于zynq-7000设计了一个八通道的超声波信号采集系统.在设计中,系统以zynq7020主控系统为核心,FPGA部分负责AD驱动开发;ARM部分主要负责数据的传输以及对整个系统的控制.系统采用采样频率为2 MHz的ADS7946芯片进行模数转换,结合AXI-Stream协议以及千兆以太网接口,实现了采集系统与PC上位机的交互,并且通过对超声波信号现场采集对比实验,证明了该系统实现了对超声波信号的采集、传输、存储以及可视化.
Design of ultrasonic signal acquisition system based on ZYNQ-7000
Aiming at the requirement of low power consumption and miniaturization of acquisition equipment in the field of non-destructive testing,an eight-channel ultrasonic signal acquisition system based on zynq-7000 is designed after analyzing the disadvantages of existing acquisition equipment.In the design,zynq7020 main control system is the core of the system,and FPGA is responsible for AD driver development.The ARM part is mainly responsible for data transmission and the control of the whole system.The system uses the ADS7946 chip with a sampling frequency of 2 MHz for analog-to-digital conversion,and combines the AXI-Stream protocol and Gigabit Ethernet interface to realize the interaction between the acquisition system and the PC host computer.Moreover,through the field acqui-sition and comparison experiment of ultrasonic signals,it is proved that the system realizes the acquisi-tion,transmission,storage and visualization of ultrasonic signals.
