摘要
从变频电源电参量实时测量的应用需求出发,针对变频电源可调频率范围宽的特点,以FPGA和DSP为硬件核心,设计出一种基于变步长自适应采样方法的数据采集计算系统。该系统具有实时性强、集成度高及扩展性灵活等特点。
Considering real-time measurement of power parameters of the variable-frequency power source and its wide frequency range, a FPGA and DSP-cored data acquisition and calculation system based on variable step-size adaptive sampling method was designed. Experimental results prove rationality and correctness of this design with real-time property, high integrated level and flexible extensibility.
