基于RFID的手持式数据读写器设计

Design of Handheld Data Reader Based on RFID

为提升当前工农业中精细化管理程度,优化产品的跟踪与记录方式,设计了一种基于RFID的手持式数据读写器。采用单片机STM32作为读写器的控制和处理核心,MFRC-522射频模块作为数据非接触式读写器件,射频IC卡作为数据的存取器件,液晶12864作为数据的显示器件,并设计了按键功能选择电路、指示灯电路和电源电路。实验结果证明,该读写器能随身携带,能对射频IC卡中数据进行读写和显示,性能稳定、响应快,实现随存随取。在精细化管理中,具有较大的实用价值。

In order to improve the current level of refined management in industry and agriculture,and optimize product tracking and recording methods,a handheld data reader based on RFID has been designed.STM32 is used as the control and processing core of the reader,the MFRC-522 radio frequency module is used as the data non-contact reading and writing device,the radio frequency IC card is used as the data access device,the LCD 12864 is used as the data display device,and the button function is designed.Select circuit,indicator circuit and power supply circuit.Experimental results prove that the reader can be carried with you,can read and write and display the data in the radio frequency IC card,with stable performance,fast response,and realizing storage and retrieval at any time.In refined management,it has greater practical value.
