摘要
"一户一表"改造是供电公司实施的一项惠民工程,是智能配网建设的一项重要组成部分,其中智能化电能表是"一户一表"改造工作的重要载体。原来使用的电能表成本高、功能简单、维护不便,给抄表、计量工作带来诸多问题。该文研制了一种基于ATT7022B的多用户多功能电能表。该电能表采用"主单片机+从计量芯片"的主从控制模式,电能计量采用分时复用原理,支持远程抄表、预付费、复费率,具有电压、电流、功率、功率因数测量和过负荷保护等功能。实践证明,本文所研制的多用户电能表的计量精度高、成本低、运行稳定,可以满足居民用户电表智能化改造的要求,具有广阔的市场应用前景。
since＂one household,one watt-hour meter＂ reconstruction project has been implemented in China, a kind of Multi-users Watt-hour Meter based on Al-17022B has been developed in this paper.The mas ter-slave MCU control model and the principles of Time Sharing Multiplex are adopted in this Watt-hour Meter,its function includes the measurement of current,voltage,power,power factor and the overload protection.It supports remote reading,pre-payment,multi-rate and etc.The practice shows that this meter has high accuracy,runs stable. It has wide prospect in the future market.
