自动识别系统应用一定的识别装置,自动地获取被识别物品的相关信息,并提
供给后台的计算机处理系统来完成相关后续处理,近几十年来它在全球范围内得到
了迅猛发展,在社会的各个领域都起到了关键性的作用。在多种自动识别技术中,
射频识别技术是最有前景的,因为它安全可靠,采集数据迅速,随着硬件成本的不
断降低,射频识别技术的优势越来越明显,必将成为二十一世纪自动识别的主流技
术。
射频识别系统主要由读写器、天线、电子标签等硬件设备和数据采集、处理中
间件等软件组成。本文对组成射频识别系统的软硬件系统的结构和工作原理进行了
详细地、系统地研究,其中研究的重点集中在数据采集中间件。
数据采集中间件是一个复杂的子系统,它包括了数据平滑和过滤,读写器协调,
数据路由和整合,过程管理,数据安全管理,外部接口等多个方面。本文通过使用
STU650A 型读写器,Tag-it HF-I 型电子标签等硬件设备和 ,Visual
C++,SQL Server 等软件系统实现了了一个完整的射频识别系统,其中根据数据采
集中间件的思想实现了数据采集模块。数据采集模块主要实现了读写器的管理,数
据格式化转换,数据过滤,数据缓冲,数据存储等功能。
最后,通过路径跟踪和家校通系统,本文展示了射频识别系统的广泛的应用前
景。在这两个系统中,对被识别对象进行编码,然后将这些数字码作为写入标签,
这样标签中的数据就有了实际的意义,它们代表了实际的产品或学生。本文重点介
绍了系统对采集数据的处理和应用,显示了数据采集系统的优越性,为将来在社会
生产生活中将其实际应用积累宝贵和丰富的经验。

Abstract
Auto-ID System applies some identification instruments to collect the information of
objects, and then provides this information to puter systems for further
processing. Auto-ID technology has been developing rapidly all over the world and it has
been playing a key role in many fields. Among the various Auto-ID technologies, RFID
technology is the most promising one because of its security, reliability and high collecting
speed. With the development of technology and science, the cost of RF hardware
decreases continuously, and the applying edge of RFID technology is more and more
manifest. In the 21st Century, RFID technology will be the mainstream of Auto-ID.
Generally, RFID System consists of hardware instruments, such as RF reader,
antenna, transponder, and ponents such as data collecting and processing
Middleware. In this thesis we study the structure and working principle ponents
constituting RFID system detailedly and systematically, and play emphasis on the study of
data-collection middleware.
Data-collection middleware is a plicated sub-system, which includes data
filtering and management, reader coordination, data routing and integration, process
management, dat
