摘　　要：针对目前用水管理部门在售水过程中效率低的缺陷,设计了一种基于智能卡的便携式手持售水终端机的方案。该终端通过射频IC卡读写模块及天线,读出用户的卡内信息,并通过LCD显示出来,用户通过按键可以输入需要购买水量的金额,然后确认进行充值,系统保存用户的实时充值信息。此设备具有体积小,成本低,功耗低,便于携带的优点,可以取代原来出售水量必须用的电脑,并且可以和电脑进行通讯。有效地保证了农田水利的安全灌溉,以及一些农产品的质量与安全。To overcome the shortage of the low efficiency of the water management sectors in the sale of water,the design for the portable handheld terminal based on t smart card l was introduced.Through the read/write module and the antenna of the radio frequency IC card,the terminal read out the users'cards'information which was displayed through the LCD.Users could enter the amount of money for buying water through the keys,and then confirm it and recharge. The users'real-time recharge information was saved.With the advantages of small size,low cost,low power consumption and portability,this equipment can replace the computer which should be used for water sale before,and can communicate with the computer and guarantee the safety of the agricultural water irrigation and quality and safety of agricultural products
