摘　　要：以CPLD和AD9240为核心器件设计了数据采集系统电路,实现了对信号的采集、存储以及传输。采用硬件编程语言(VHDL)完成了通讯接口、AD采集及数据存储时序设计、采样时钟管理模块设计等,实现了对爆轰波等信号的完整采集功能。该设计可有效简化电路的复杂性、降低应用成本。Taking CPLD and AD9240 as core components, we designed data acquisition system circuit to achieve acquisition, storage and transmission of signal in this paper. Hardware programming language was adopted (VHDL), the communication interface, AD acquisition, data storage timing design, sampling clock management module design and so on were completed, the complete acquisition function of detonation wave and other signals was realized. This design can effectively simplify the complexity of the circuit and reduce the application cost.
