摘　　要：随着物联网、人工智能等技术的飞速发展,基于物联网的“人-机-物”智能感知识别技术成为当前研究的热点方向。在众多的感知识别技术中,射频识别技术(Radio Frequency Identification, RFID)作为物联网的核心技术之一,被广泛应用在物流追踪、身份认证和室内定位等各个领域。由于目前广泛使用的个人移动设备并不支持RFID信息读取,限制了RFID技术的大范围应用。针对智能手机不能直接读取RFID标签信息的问题,提出一种利用用户预定义的基于RFID反射信号的手势特征实现面向智能手机和RFID标签之间的跨域互联方法。该方法不需要对部署的RFID系统或智能手机进行任何硬件修改,通过用户在感兴趣标签面前做出手势而产生的RFID相位特征,并与智能手机捕获到的运动传感器数据的相关时间戳进行匹配,从而实现了智能手机与RFID标签的关联配对。最后,通过实验验证了文中提出的跨域互联方法的可行性。With the rapid development of Internet of Things(IoT)and artificial intelligence(AI)technologies,the‘human⁃machine⁃things’intelligent perception and recognition technology based on IoT has become a hotspot.Among those perceptual identification technologies,radio frequency identification(RFID),as one of the core technologies of the IoT,has been widely applied to various fields,such as logistics tracking,identity authentication and indoor positioning.However,the limitation that smart phones cannot read RFID tags impedes more applications of RFID.In this regard,a cross domain interconnection method between mobile terminals and RFID tags is proposed by using the users􀆳predefined gesture features based on RFID reflected signals.This method does not modify any hardware of current RFID systems or smart phones.The RFID phase feature generated by the user􀆳s gesture in front of the tag of interest is matched with the relevant time stamp of the motion sensor data captured by the smart phone.Thus,the association and pairing between the smart phone and the RFID tag can be realized.Finally,the feasibility of the proposed cross domain interconnection method is verified by experiments.
