摘要
针对物流系统特性开发RFID的技术产品,以基于ARM的RFID读写器核心模块作为硬件基础,在微处理器能把由R1000数字信息处理器产生的原始数据转换成EPC或18000-6c格式的代码的基础上进行应用层程序设计和操作系统设计,运用模块化和结构化编程思想,通过底层程序、防冲突程序、数据加密等关键程序设计,从而实现与上位机的串行通信过程,完成EPC协议中规定的对射频卡的各种操作,使得读写器更加协调地读取电子标签。
According to the technical product development RFID logistics system characteristics, using ARM RFID reader based on the core module as the hardware foundation, the microprocessor can based on the raw data generated by R1000 digital signal processor into EPC or 18000-6c format code for design of application layer program design and operating system, the use of modular and structured programming thought, through the bottom of the program, the anti-collision program, data encryption key program design, so as to realize the serial communication process and PC, complete the EPC protocol in the various operations of RF card reader, so that a more coordinated read electronic tag.
