摘　　要：在分析∑-△A/D转换器工作原理的基础上,设计了一款单相数字电能表。以AT89S52单片机为控制核心,采用带有串行接口的单相双向功率电能集成芯片CS5460A,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,有很好的实用开发价值。This paper designed a single-phase digital watt-hour meter on the basis of the principle of A/D converters. It had accomplished single-phase electricity power measure, display, storage and query functions based on the control of AT89S52 and the single-phase bi-directional power integrated chips CS5460A with serial interface. The experimental results showed that the watthour meter with high sensitivity, accuracy, guard against electricity theft, and other advantage, had some practical value.
