基于嵌入式系统的IC卡电表可靠性研究

Study of IC card Kilowatt- Hour Meter credibility based on Embedded system

在嵌入式系统应用中抗干扰是一个很重要的问题。特别是在与电力网相关的控制系统的设计和实际制作过程中,系统的可靠性差,将会引起许多意想不到的问题。我们在基于嵌入式系统的IC卡电度表中除采用常规软件抗干扰措施外,针对实际情况还采取了一些特殊技术,并取得了很好的效果。

Anti-interference is a very important problem in the embedded system .Especially in the control system design correlated with the electric power network , a lot of unexpected questions should be presented without enough attention and efficient methods , and the reliability of control system can not be guaranteed . In this paper, we will introduce our effects and experience in this respect.
