摘 要: FPGA可以在数据采集系统中取代单片机和DSP对数据采集过程进行控制。基于FPGA的数据采集系统具有时序快、组成方式灵活、易于修改的特点 ,适合于高速数据采集的场合。设计中采用了自顶向下的方法 ,将FPGA依据功能划分为几个模块 ,详细论述了各模块的设计方法和控制流程。系统可应用于电力远动监控 。 FPGA can replace MPUs and DSPs in controlling the data acquisition process in data acquisition system. The system based on FPGA has the characteristics of high speed, functional agility and easy to modify. Hence it is especially suitable for the highspeed data acquisition. According the method of top down, FPGA is divided into some functional modules. The designing method and controlling flow of each module are discussed in detail. The data acquisition system can be used in remote power supervising and controlling. Simulation results demonstrate the validity of the data acquisition system.
