射频识别（RFID）节点技术设计及应用开发摘要：本文以 STC11F32XE 单片机为核心，设计了一个无线射频识别的读卡器。本设计中，印制在PCB 板上的磁场耦合天线通过磁场感应收集到 IC 卡上的数据信号（这里是模拟信号），然后天线将收集到的数据信号传回给 TRF7960 无线射频识别芯片，TRF7960 再将此信号进行数据预处理，即模拟信号的数字化，然后将此数字化后的信号通过串口通信的方式传送给 STC11F32XE 单片机，STC11F32XE 单片机会驱动 12864 液晶，最终将 IC 卡上的数据信息显示在 12864 液晶屏上。 文章详细介绍了 TRF7960 芯片的工作原理和读卡器具体的硬件与软件设计方案、思路及实现方法。设计中，功能实现的步骤包括寻卡、读卡和中断等，该读卡器可实现对 ISO14443A 类型卡的识别功能。关键词：射频识别；非触碰式 IC 卡；读卡器；TRF7960；ISO14443ARadio Frequency Identification (RFID) Technology Node Design and Application DevelopmentAbstract: This paper STC11F32XE microcontroller as the core, a radio frequency identification of the card reader is designed. The design, magnetic field coupling antenna is printed on PCB through the magnetic field induction to collect data on the IC card signal (analog signal here), then the data signal will be collected by the antenna back to the radio frequency identification chip TRF7960, this data signal again be pretreatmented by TRF7960, namely of the analog signal digital, then will the digital signal through serial communication transmitted to the way STC11F32XE microcontroller,12864 LCD Wwill be drived by STC11F32XE microcontroller, will eventually IC card of data on information displayed in 12864 on the LCD panel. The TRF7960 chip works, reader specific hardware and software design solutions, ideas and implementation are detailed in this article. Design features to achieve the steps include seeking cards, readers and interruption, the reader can achieve the type of card ISO14443A recognition.Key...
