Manual tags-scan has restricted the wider application of radio frequency identification (RFID) technology in archives management.The intelligent antenna splitter working in 902～928 MHz is added to the RFID system.With four stage cascades of the main splitter and sub splitter,256 antennas can be switched in the system at most.The connection and reading of the reader,and the splitter query cascade and antenna switching of the antenna splitter are controlled through Visual Studio upper computer,with which the accurate matching of thearchive tags and the antenna position can be done.The fast check,locating search and malposition reminding of archive management were realized.This method avoids scanning the tag with multiple readers manually,and makes the archive management more intelligent and convenient.%需要人工扫描标签的操作一直制约着无线射频识别(RFID)技术在档案管理中的应用.在RFID射频系统中加入工作频率为902～928 MHz的智能天线分支器,通过主分支器和子分支器的四级级联,系统最多支持256路天线切换.再通过Visual Studio上位机编程控制读写器的连接和读取,以及天线分支器查询级联和切换天线,就可以将档案标签和天线位置准确匹配,实现了档案的快速盘点、定位查找和错位提醒.该方法避免布置多个读写器,也不需要人工扫描标签,使得档案管理更加智能快捷.
