【摘要】 结合高速FPGA的特点,设计了一套数据采集系统。该系统以FPGA作为采集系统的核心,应用FPGA的内部逻辑实现时序控制,对数据进行采集、显示,并将处理后的结果通过USB口传输到上位机。该系统具有电路结构简单、功耗低等优点,可用于温度、压力等传感器信息以及电压、电流的数据采集。更多还原

【Abstract】 A set of data acquisition system which combined characteristics of high speeding FPGA was developed. The internal logic of FPGA was used to control time sequence. It took FPGA as the core to read the acquisition data, show and transmit data by USB interface. The system has a simple circuit structure, low power consumption and so on. It can be used as the acquisition system of pressure voltage, temperature parameters, voltage and current.更多还原
