所述射频信号处理单元12与天线单元11和处理器13连接，所述射频信号处理单元12用于对于天线单元13所发射的频段信号以及通过天线单元11接收到的RFID标签数据进行处理，比如通过天线单元13激活RFID标签、获取RFID标签中存储的信息、向RFID标签中写入信息以及对读写器一次读取到的多个RFID标签进行多信号处理，比如群读防撞(当有多个RFID标签均处于可测范围时，如何对于多个RFID标签分别进行读取和处理，以避免干扰)等。在本公开一实施例中，所述射频信号处理单元12还包括滤波器，用于在读写器一次读取到多个RFID标签数据时，对于多个RFID标签数据进行滤波处理，以获得高精度和高准确度的RFID标签数据。
优选地，所述射频信号处理单元12采用可处理超高频段信号的芯片处理器。
本领域技术人员可以了解，RFID标签是被动的，需要读卡器对其供电，所述射频信号处理单元12可以将能量通过天线发送给RFID标签，这时RFID标签会被激活，开始与读卡器通过天线通信。该通信的基本目标就是获取RFID标签上存储的信息，或者向RFID标签写入信息。但具体的获取过程取决于不同的标准，比如像EPCglobal 2的UHF标准，或者其他标准。
所述处理器13主要负责对通过射频信号处理单元12和天线单元11接收到的RFID标签数据进行处理，对RFID标签数据按照通信单元14 所支持的数据格式要求进行封装，并向通信单元14发送传送数据的命令，从而通过通信单元14将从天线单元11获得的RFID标签数据发送到其它通信设备上。

其中，所述处理器13至少包括数据处理芯片和封装单元，所述数据处理芯片用于对通过射频信号处理单元12和天线单元11接收到的RFID标签数据进行处理；所述封装单元用于将数据处理芯片处理后的RFID标签数据根据通信单元14所支持的数据格式进行封装。所述通信单元14与所述处理器13连接，主要负责所述可穿戴式RFID读写器与外部设备如PC端或移动设备等进行实时通信，从而将所述处理器13处理过的RFID标签数据，发送给外部设备进行进一步的分析处理或应用。
所述通信单元14至少包括通信芯片，所述通信芯片可以是有线通信芯片也可以是无线通信芯片，所述无线通信芯片可以为远程无线通信芯片也可以为近场无线通信芯片，所述远程无线通信芯片可以为以移动通信技术为支持的通信芯片，比如GPRS通信芯片、2G通信芯片、3G通信芯片、4G通信芯片等，或者多个无线通信芯片的组合；所述近场通信芯片可以为蓝牙通信芯片、红外通信芯片、WIFI通信芯片、传感器通信芯片、信标通信芯片等，或者多个近场通信芯片的组合。需要特别说明的是，上述通信芯片只是示例性的说明，并不用于限制本公开，任 何可实现远程、近场通信的组件均落入本公开的保护范围。在本公开一实施例中，采用WIFI通信芯片与外部设备进行实时通信和数据传输，从而使得后期数据处理设备，比如计算机，可以对于可穿戴式RFID读写器获得的RFID标签数据内容进行进一步处理和分析。
所述供电单元15的电源输出端与所述射频信号处理单元12、处理器13和通信单元14的电源输入端连接，以为所述射频信号处理单元12、处理器13和通信单元14提供电源。
所述供电单元15可为锂电池、聚合物电池、蓄电池、太阳能电池或上述电池的组合，在本公开一实施例中，所述供电单元15为聚合物电池，以减轻所述可穿戴式RFID读写器的重量。
所述固定单元2使用或者主要使用非金属材料制作，比如塑料、橡胶、纺织材料等，事实上，只要固定天线单元211的固定单元22部分或者附近不存在金属材料就可以。进一步地，所述固定单元2可以由柔性非金属材料制作也可以由非柔性非金属材料制作，具体的材料选择取决于所述可穿戴式RFID读写器的穿戴部位，比如所述固定单元2可制作为橡胶脚套，可制作为布质手环臂环、柔性项圈、针织手套，甚至还可以制作为可夹在人体某个部位或者衣物上的便携设备，用户还可以根据实际应用的需要定制符合人体工学的具体实施方式。
所述固定单元2与读写器本体1可通过多种方式连接，比如通过连接件进行物理连接或者直接制作为嵌入式连接，比如所述读写器本体1可以通过连接件固定在所述固定单元2的表面或一侧，也可以将固定单元2制作成环状，将读写器本体1嵌入或者分散嵌入到所述固定单元2中，这里分散嵌入的意思是将读写器本体1中的各个单元独立嵌入到固定单元2中，比如将柔性天线单元嵌入至被损坏风险较大的位置，将非柔性的处理器、供电单元和通信单元嵌入至被损坏风险较小的位置，已对其进行保护，当然，即使柔性天线单元不容易被损坏，但其形变会对收发性能产生不利的影响，因此也可将天线单元与其他单元一并放置在被损坏风险较小的位置上。需要特别说明的是，固定单元2与读写器本体1的连接方式只是示例性的说明，并不用于限制本公开，任何可实现 地、合理的连接方式和连接组件均落入本公开的保护范围。
以上仅为本公开的优选实施例，并非因此限制本公开的专利范围，凡是利用本公开说明书及附图内容所做的等效结构或等流程变换，或直接或间接运用在其他相关技术领域，均同理包括在本公开的专利保护范围内。
