摘　　要：针对PR9200芯片的超高频、无线射频识别读写器通信效率低下的问题,设计了一种基于FPGA的通信方案。介绍了数据通信的架构,制定了通信协议的传输规则,采用工业以太网口通信,并通过FPGA对传输的数据进行并行处理后送至MCU。仿真与测试验证表明,该读写器通信系统能有效地提高数据传输及处理速度,与原系统相比,通信效率提高了57%,且不影响系统稳定性,可应用于高速的标签识别中。Aiming at the problem of low communication efficiency of UHF( Ultra High Frequency) radio frequency identification reader based on the PR9200 chip,a field-programmable gate array( FPGA) based communication scheme was designed. This scheme introduced the data communication architecture,formulated the communication protocol transmission rules,adopted industrial Ethernet port communication,and sent the data to the MCU through field programmable gate array( FPGA) for parallel processing. After testing,the results show that the reader communication system can effectively improve the speed of data transmission and processing. Compared with the original system,the communication efficiency is improved by 57% without affecting the system stability,and can be applied to high-speed tag identification.
