摘要
传统的以MCU为架构的数据采集系统,在用于高速数据采集时往往力不从心,而FPGA以其并行的数据处理方式,可以更好地满足于工程数据的采集。本文结合高速FPGA的特点,设计了一套数据采集系统,应用FPGA的内部逻辑实现时序控制,以FPGA作为采集系统的核心,对采集到的数据通过USB口传输到计算机。该系统具有电路结构简单、功耗低、数据传输方便等优点,可用于电压、电流、温度等参量的采集系统中。
With parallel data processing method, FPGA can better meet the engineering data collection, In this paper, A set of data acquisition system which combined characteristics of high speeding FPGA developed. The internal logic of FPGA was used to control time sequence. And it took FPGA as the core to read the acquisition data. and transmit data by USB interface. The system has a simple circuit structure, low power consumption,data transmitting convenience and SO on. It can be used a8 the acquisition system of voltage, current and temperature parameters.
