RFID读写器内存数据结构

Data Structure in Memory of RFID Reader

在大型RFID应用中,需要将标签数据处理环节前移至读写器。由于读写器的硬件条件限制,要提高读写器的实时数据处理能力,就必须有适合RFID应用的高效的数据处理算法及存储结构。分析了RFID读写器数据处理的特点,提出了一种特殊的T链表树结构。在T树的结构基础上增加了双向链表结构,使得读写器在读周期的各个数据处理阶段都能保持很高的效率。在T链表树结构基础上,还设计了一套数据处理算法,结合特殊的数据结构,可以极大地提高读写器的实时数据处理能力。

In the large-scale application of RFID, it is necessary for tag data processing to be moved to readers.Due to hardware conditions of readers, it is imperative to have an effective arithmetic for data processing and data structure to improve real-time process capability of readers. Data processing features of RFID readers are analyzed and a special T-linked tree is put forward. On the basis of T tree, there is a doubly linked list structure added, which enables readers to maintain high efficiency at each stage of data processing in read cycles. In addition to Tlinked tree, a set of arithmetic for data processing with a special data structure is devised, which can enhance synchronous process ability of readers.
