摘　　要：利用ARM和用户数据报协议(UDP),实现了声表面波射频识别系统的阅读器上、下位机UDP通信功能。与串口通信相比,UDP通信充分利用以太网资源进行上、下位机之间的数据交换,数据传输速率可达100Mbit/s。在完成上、下位机UDP通信的基础上,系统实现了网线热插拔功能。基于C#软件设计了上位机人机界面,不仅能显示声表面波标签回波信号并解算标签编码,还可通过人机界面对下位机进行控制,实现了人机交互功能。The UDP communication function between the reader's upper and lower computer of the surface acoustic wave radio frequency identification system is realized by using the ARM and the UDP protocol.Compared with the serial communication,the data transfer rates of UDP communication can be up to 100Mbit/s,which makes full use of Ethernet resource for data transfer.Based on the UDP communication,the system supports the hot plug of the Ethernet cable.The human-machine interface of the reader upper computer is designed by the C# software,which can display the tag echo signal and decode the tag.Also the lower computer can be controlled by the interface,by which the human-computer interaction function is realized.
