摘要
本文提出一种用于微机继电保护的ＣＰＵ主板的新设计方法。用一片８０Ｃ１９６ＫＢ（ＣＰＵ）和两片ＡＤ７７９ＫＮ（ＡＤＣ）实现了８路电力参数信号的近似同相位的数据采集，系统分辨率为１４位。
This paper presents a new design method of CPU Board for microcomputer relay protection.It presents a data acquisition system which uses one 80C196KB(CPU) and two chips of AD779KN(ADC) to sample 8 channel power signals approximately simultaneously.The resolution of the system is 14 bit.
