【摘要】： 无线射频识别技术(RFID)是一种新的自动识别技术,发展十分迅速。它的应用领域非常广泛,例如高速公路自动收费及交通管理、门禁保安、RFID卡收费、生产线自动化、仓储管理、汽车防盗、物流等。随着RFID技术应用的不断扩展,RFID中间件成为了RFID技术的研究热点。 RFID中间件是位于RFID硬件系统和RFID上层应用系统之间的软件,它的主要功能包括:屏闭低层硬件系统的特性,为上层应用系统提供统一的API接口;管理读写器;处理读写器反馈的原始标签数据。RFID中间件可以降低硬件系统与上层应用系统的耦合度,并为上层应用提供有效可靠实时的签信息。目前,已经有很多成熟的RFID中间件产品,这些中间件都是大型的软件,只能运行在PC或服务器上,而且价格昂贵。针对这种情况,本文提出并设计实现了一个嵌入式RFID中间件,该中间件基于EPCglobal的中间件标准Application Level Event(ALE),它能够运行在嵌入式的Linux系统上,在提供高效服务的同时,大大降低了中间件的成本,特别适合中小规模的应用。本文首先深入分析研究了ALE的技术规范,根据嵌入式设备的特点,提出了嵌入式中间件的设计要求;然后根据规范设计软件的系统架构和程序流程;最后是对软件的测试。
[Abstract]:Radio Frequency Identification (RFID) is a new automatic identification technology, which is developing rapidly. It is widely used in many fields, such as highway automatic toll collection and traffic management, entrance guard. RFID card charging, production line automation, warehousing management, automobile theft prevention, logistics, etc. With the continuous expansion of RFID technology application, RFID middleware has become a research hotspot of RFID technology. RFID middleware is the software between the RFID hardware system and the RFID upper application system. Its main functions include: the characteristics of the lower level hardware system. Provide unified API interface for upper application system; Manage the reader; The RFID middleware can reduce the coupling degree between the hardware system and the upper application system, and provide effective and reliable signature information for the upper application. At present, there are many mature RFID middleware products, these middleware are large software, can only run on the PC or server, and expensive. In this case. This paper proposes and designs an embedded RFID middleware. The middleware is based on the middleware standard of EPCglobal, Application Level event / event / Alley, which can run on embedded Linux system. At the same time, the cost of middleware is greatly reduced, which is especially suitable for small and medium scale applications. In this paper, the technical specifications of ALE are analyzed, and the design requirements of embedded middleware are put forward according to the characteristics of embedded devices. Then design the system structure and program flow of the software according to the specification; Finally, the software is tested.
