一种NFC智能水表的设计与实现

Design and Realization of a NFC Intelligent Water Meter

为改进传统预付费水表的不足,从NFC(Near Field Communication)工作模式及协议架构出发,利用NFC协议唤醒机制大大降低系统功耗,设计并实现了具有NFC通信功能的预付费智能水表。用户无需移步至水费充值网点在家即可充值水费或查询用水量,管理部门也可及时获取水表状态和掌握用户详细的历史用水数据。既满足用户快捷的支付需求,也可方便水司管理。

To improve the shortcomings of traditional prepaid water meters, the prepaid intelligentwater meter which has the function of NFC （ Near Field Communication） was designed and imple-mented. The NFC work mode and protocol architecture are analyzed firstly, then the intelligent wa-ter meter using NFC protocol wakeup mechanism greatly reduce the system power consumption. Us-ers can prepaid the water rate or query water at home instead of voucher center. Management can betimely access to the state of water meter and mastering the detailed historical user data. The NFC in-telligent water meter can meet user the demand of quick pays, and the water management depart-ment enables convenient management.
