摘要
超高频RFID标签感应距离远、读写速度快,抗干扰能力强以及有限的存储能力。分析了RFID标签的性能和存储空间,提出了以RFID标签为记录载体、无需网络和数据库支持的移动考勤模式。通过编码,团队成员的基本信息如姓名、性别、年龄段和手机号码等记录在EPC存储器的96比特可写入段,扩展信息存储在标签用户存储器中。姓名汉字编码消除首字节高位冗余信息,手机号码的高3位和低8位独立编码,使成员基本信息得到压缩与保密。
Ultra-high frequency RFID tags provide some performances such as long response distance,fast read-write speed,high anti-interference ability and limited memory.Performance and memory structure of tags are analyzed.A novel mobile attendance method without networks and databases is proposed,in which RFID tags are record medium.Through encoding,basic information of team member such as name,sex,age and mobile phone is stored in writable segment of EPC memory in tags,and extend information is stored in user memory.Chinese codes of name are encoded by eliminating redundant.Mobile phone is encoded by dividing into 3 bits and 8 bit.Basic information is compressed and kept secret.
