摘要
论文描述了以EP2C5Q208C8N、AD7621以及CH368为核心的声发射数据采集系统的硬件设计,主要提到了系统的实现原理、硬件模块的组成及相应的电路设计.通过Altera公司的Modelsim仿真对模块电路整体工作的过程进行验证,最后采用GWINSTEK函数发生器产生的无直流偏置幅值为4 Vpp、频率为200 kHz正弦波验证系统的硬件指标,验证发现硬件指标可以满足声发射信号采集所需的16 bit分辨率,3MSPS采样率设计要求.
Abstract
This article describes the hardware design of the acoustic emission data acquisition system with EP2C5Q208C8N,AD7621 and CH368 as the core,and mainly mentions the implementation principle of the system,the composition of hardware mod-ules and the corresponding circuit design.The overall working process of the module circuit is verified by Altera's Modelsim simula-tion.Finally,the GWINSTEK function generator is used to generate a sine wave with no DC bias amplitude of 4 Vpp and a frequen-cy of 200 kHz to verify the hardware indicators of the system.It is verified that the hardware indicators can meet the 16 bit resolution and 3MSPS sampling rate design requirements for acoustic emission signal acquisition.
