Standard study and hardware design of telecom power's supervision unit

Based on a new standard,YD/T1363-2005,this paper introduces the comparative study on differences between the new standard and the old one from the perspective of supervision system for power.The study is composed of three major parts:definitions and technical terms,structure of supervision system,and supervision objects.The new design of supervision unit,based on AT91RM9200,is developed,and some discussions about every single module are given,such as ADC and ethernet module etc.The new design presents the remarkable advantages.
