摘要
针对目前传统单片机控制采集速度低、非实时以及插卡式数据采集卡拆卸的不方便、体积较大等一系列缺陷,设计了一种以FPGA为控制器,运用合理的编程逻辑控制相关的外围电路,用于暂态信号测量的高速数据采集系统。在QuartusⅡ平台下采用Verilog HDL描述语言对设计进行软件编程,完成对AD 9280芯片的时序控制;采样后的数据经SDRAM存储器存储并以串口方式发送至PC机进行后续的数据处理。整个设计方便、小巧、便携,仿真及试验结果显示系统稳定性好、可靠性高。
Due to the defects of traditional MCU,such as low acquisition speed,non-real-time,large size,and not convenient to dismount the traditional data acquisition card. The design of the data acquisition system for the measurement of transient signal with FPGA is presented. The whole design is based on the QuartusⅡplatform. The process is described by the Verilog language to realize the correct sequence of AD9280 converter controlling process and store the sampling data through SDRAM to PC. The whole design is portable and easy to use. The simulation and experimental results show that the design has the advantages of stable performance and high reliability.
