摘　　要：设计了以FPGA(现场可编程门阵列)为核心逻辑控制模块的高性能数据采集系统,该系统除了可完成2 4路最大采样频率为10 0 k Hz(精度16位)的模拟信号采集和8路宽范围频率信号采集,还具有较强的数字信号处理能力和一定的容错、自检功能。FPGA模块采用VHDL语言设计,在MAX+PLUSII集成环境中进行软件设计和系统仿真,本文给出了FPGA主要功能模块的仿真图形。The high-performance data acquisition system based on FPGA is designed. It not only achieves acquiring 24-route analog signals with maximal frequency of 100 kHz (precision is 16 bits) and 8-route wide-range frequency signal, but also has the ability of data signal processing and the function of fault tolerance and self-examination. The VHDL language is adopted in the FPGA module. The software design and system simulation are completed in the integration circumstance of MAX+PLUSII. The paper provides the simulation figures of main FPGA modules.
