摘要
本设计基于瑞萨公司的R7F0C004M2DFB单片机,提出了单相费控智能表电能表(CPU卡)的设计方案,给出了费控功能的硬件设计框架和系统插卡主流程结构。本设计在高性能MCU、ESAM加密技术与CPU卡基础上,重要数据增加CRC校验,具有成本低、精准计量、安全可靠等特点。
Based on MCU of Renesas Electronics corporation, a design scheme of single-phase smart meter with cost-control （CPU Card） is proposed. In this paper, the cost-control of hardware design framework and the main flow structure of the system are given. Base on high performance MCU, ESAM encryption technology and CPU card, the important data increase the CRC check. This Meter has the characteristics of low cost, accurate measurement and so on.
