摘　　要：本文设计了一款以FM2307专用芯片为核心实现的三相预付费复费率电能表,具体介绍了硬件的四大模块及其接口设计和软件的实现。该表能实现红外、RS485和IC卡通信三种通信功能,预付费复费率部分实现单芯片解决方案,外围器件少,结构紧凑,具有很好的市场前景。This paper designs a prepayment multi-rated three-phase watt-hour meter which is based on special purpose chip FM2307,four modules hardware circuits,their interface design and the software realization are concretely introduced.lt can implements three kinds of communication including IC card,infrared and RS485 communications,the prepayment multi-rated part carry out a sin- gle chip solution,the peripheral circuit is few and the structure is compact. This watt-hour mete has has good marketplace prospect.
