摘要:提出的改进型IC卡预付费智能水表系统,在传统设计的基础上,采用双干簧管传感器,可判别水流方向,并提高抗强磁干扰能力。系统以短信猫取代传统智能水表的显示屏和报警装置,在强拆除、电源欠压、水费不足、强磁干扰等情况下,自动发送短信提醒用户。在非工作状态下,系统各部分处于掉电状态,更进一步降低功耗,实现节能。

Abstract:In this article,prepayment intelligent water meter system which based-on IC card is improved. By reed switches, reed sensor not only can distinguish the water flow direction, but also gets high performance on electromagnetic interference in system. To replace the display and alarm device, my system uses SMS cat sending messages to remind users when in specific cases. In non-work station, each part of the system goes into power-off station, further reduce the power consumption.
Key words:IC card;prepay;intelligent water meter;SMS cat;low power consumption
