摘要

随着社会生产力的发展,科学技术的不断进步,射频识别(Radio Frequency Identification,RFID)技术近年来由于其显著的优点得到了广泛的应用,为了让作为RFID系统神经中枢的RFID中间件可以更好、更快地得到应用,使其能适应更多的应用需求,对现有的RFID中间件进行改进与优化是十分必要的,本文研究基于Java的分布式系统-Jini,给出基于Jini的RFID中间件平台的总体架构,利用RMI通信方式,实现RFID设备(虚拟的设备)在Jini环境下的自动识别、RFID中间件在Jini环境下的自动配置和管理以及RFID设备的"即插即用"的功能,同时对RFID中间件在Jini环境下的管理进一步地进行优化,使得基于EPCglobal标准的RFID中间件的设备配置与管理能在分布式环境下高效地运行.最后在实验中验证RFID中间件在Jini平台中的"即插即用"性.本文为RFID中间件与现代技术的结合提供思路和方法参考.%With the development of social productive forces and the advances of science and technology, Radio Frequency Identification(RFID) technology has been widely applied in recent years for its significant advantages. In order to make use of RFID systems better and faster to adapt to mere applications, it is necessary for us to improve and optimize the existing RFID middleware. This arficle is mainly for the optimization and improvement of RFID middleware communication mechanism. Based on the Java-based distributed system named Jini, this paper proposes the architecture of Jini-based RFID middlewarc, using RMI communication mechanism to implement the automatic identification of RFID device (virtual device) in middlewarc, realizing automatic configuration and management of RFID middleware as well as the “plug and play” of RFID devices. Meanwhile, the management of RFID middleware in the Jini environment is further optimized, making the configuration and management of RFID middlewarc based on EPCglobal standards mare efficiently in a distributed environment. Finally, through test cases, the “plug and play” of the RFID middleware is verified in the Jini platform. The paper provides a new idea and method for RFID middleware and modem technology.
