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。 In order to improve the shortage of traditional prepaid water meters, based on NFC (Near Field Communication) working mode and protocol architecture, using NFC wake-up mechanism greatly reduces system power consumption and designs and implements a prepaid intelligent water meter with NFC communication function. The user does not need to move to the recharge point to recharge the water charge at home or check the amount of water, the management department can also get the water meter status and grasp the user detailed history of water data. Both to meet the fast payment needs of users, but also to facilitate water division management.
