摘　　要：在分析了CS5460A工作原理的基础上,设计了一款单相数字电能表。它采用以AT89S52单片机和带有串行接口的单相双向功率电能集成芯片CS5460A为控制核心,在软件设计中嵌入了实时操作系统uC/OSⅡ,能实现单相电量的检测、显示、存储和查询功能,实验结果表明:该电能表具有高灵敏度、准确、防窃电等优点。This paper designed a single-phase digital watt-hour meter on the basis of the principle of CS5460A. It had accomplished single-phase electricity power measure, display, storage and query functions based on the control of both AT89S52 and the single-phase bi-directional power integrated chips CS5460A with serial interface, embedded the realtime operating system uC/OS Ⅱ in the software design. The experimental result showed that the watt-hour meter had high sensitivity,accuracy,guard against electricity theft and other advantage.
