基于FPGA+AD7606的电力线监测系统的设计

Design of Power Line Monitoring System based on FPGA and AD7606

在电力线监测系统中,模数转换(ADC)是影响系统监测性能的重要指标。在分析电力线监测系统对动态范围、采样通道等要求的基础上提出了一种新型的基于FPGA+AD7606的设计方案。该方案通过FPGA内置AD控制器实现了对AD7606的驱动,减轻了CPU的负担,提高了系统性能的同时还降低了整体系统的成本,减小了电路板面积,具有非常广阔的应用前景。

In Power Line Monitoring System,analog-to-digital（ADC） is a key link which affects detection performance of the system.Present a new design used by FPGA and AD7606 based on the analyzing of the present development situation of Power Line Monitoring System to the need of dynamic range,the number of sample channels and so on.This design takes use of an AD controller which is integrated by FPGA to drive the AD7606,this method not only relieves CPU ＇s burden and improves the system ＇s performance,but also reduces the entire system ＇s cost.This method would have a wide prospect.
