Keyword:  智能搜索UHF读写器MSP430;
Abstract: 在当今的现代化社会,科技发展迅速,物品向小型化、微型化发展已经成为一种必然[1]。本设计通过在指定的物品上挂载标签,采用UHF射频卡读写器作为控制核心对目标标签加以识别与读取,配合链接MSP430处理器[2]及自制的圆极化天线,实现了物品的定位功能,并通过配合使用GSM模块,以短消息的方式告知主人物品的位置及安全信息。标签的信息可通过PC机键盘输入进行更改。UHF射频卡读写器中的防碰撞算法保证了标签读取的抗干扰性和稳定性[3],自制天线的高增益和优良性能为有效搜索范围提供了保障。本文网络版地址:http://www.eepw.com.cn/article/271651.htm
