Design of distributed RFID data collection system based on Zig Bee and ARM

针对传统有线射频识别(RFID)技术信息采集系统存在布线成本昂贵、节点众多时连线复杂、读写器需要预先部署且灵活性差、无法在移动载体上读取等问题,提出采用Zig Bee和ARM处理平台构建分布式RFID信息采集系统。在建立ARM最小系统基础上,结合UART,USB和LCD等外围设备构成嵌入式RFID信息处理平台,并针对分布式RFID信息采集的特点,引入Zig Bee无线通信技术,利用Zig Bee无线组网的灵活性和ARM强大的运算处理能力,实现了分布式RFID信息采集。详细介绍了系统的整体架构和主要模块的软硬件设计与实现,实验结果验证了该系统的可行性和有效性。

Aiming at the weak points in traditional wired RFID data collection system, such as high cost of cabling, nodes connect complex, reader need predistribution, low flexibility and can＇ t read in mobile carriers, a distributed RFID data collection system based on Zig Bee and ARM is proposed. On the basis of the establishment of embedded minimum system based on the ARM, a RFID information processing platform is constituted combining peripherals such as UART, USB, LCD and et al. Aiming at the characteristics of the distributed RFID data collection, Zig Bee wireless communication technology is introduced. Taking full advantage of the flexibility of Zig Bee wireless networking and ARM powerful computing capability, the distributed RFID data collection is realized. The structure and the software and hardware design and implementation of main modules in the system is given in detail, and the result shows thai the system is effective and reliable.
