摘　　要：为了解决IC卡预付费电能表存在的问题,继承先购电后用电的管理模式,设计了一种多用户电能表。电力部门的管理微机通过RS485网络对电能表进行管理,以防止用户窃电;选用射频卡作为用户卡以解决IC卡易被污染和损坏的问题;采用一表多卡方式来满足公共场所用电管理的要求。This design＇s main purpose is solve the disadvantage of Prepayment IC card Watt-hour meter.It is a multiuser watt-hour meter base on RFID and it adopts the model of prepayment too.In order to prevent the user stealing the electric energy,the electric department＇s microcomputer carries on the management through the RS485 network to the Watt-hour meter;It takes the radio frequency card as user card to solve the problem which IC card is polluted and damaged easily ;It adopts muhiuser＇s mode to satisfy the need of public places＇ electrical management.
