摘　　要：讨论了一种非接触式IC卡在节水控制上的应用。通过STM32单片机和通用读卡芯片FM1702SL实现对MIFARE卡的读写增减等基本操作,给出了天线设计规范,采用SGL8022K触摸芯片实现触摸操作,具体给出了读卡器的硬件设计电路图和软件设计流程图,阐述了MIFARE卡的编程规则和使用方法。经实际使用证明,该系统具有电路稳定、读写基本无误、防掉电、易嵌入到其他模块组合使用、低功耗、低成本的良好性能,具有很大发展前景。This article mainly discusses a kind of application in water saving control based on a contactless IC card. Through using MCU STM32 and universal untouched card reader FM1702SL this system finishes reading, writing, in- creasing and decreasing, which are basic operations. In addition, the antenna design specifications are given and the system use SGL8022K to accomplish the touch operation. The hardware circuit, the software flow chart, and the usage of MIFARE card are given in the article. By actual using, the system proves that it is circuit stable, read-write correct, power-down prevent, easy to embed in other modules, low power consumption, low price, which has a wide potential market.
