摘要
主要对智能电表用CPU卡的物理结构、数据交换、指令系统等基础知识进行了整理,结合大量的实践应用,对卡口防攻击电路进行了分析描述,对软件部分关键的认证流程和表内购电流程进行了深入的论述。侧重于理论与实践应用相结合,从硬件及软件两方面论述CPU卡在智能电表中的应用。
The basic knowledge of CPU card for smart meter such as physical structure, data exchange, instruction system, etc are sorted out. Based on a large number of practical applications, the anti - attack circuit for card slot is described and ana- lyzed. Some key parts of certification process and the electricity procurement process in this software are discussed. The focus is on the combination of theory and practical application, and the application of CPU card to smart meter is discussed from two aspects of hardware and software.
