【摘要】：射频识别(Radio Frequency Identification, RFID),是一种具有广泛的应用前景非接触的自动识别技术。在RFID应用系统中,RFID中间件是其中重要的组成部分,其作为将RFID读写器设备与上层应用系统连接起来的中间桥梁,负责它们之间的数据信息交互。物联网技术发展中RFID产业规模位居前列,其应用已遍及智能化工业,畜牧业,农业,物流,交通,贸易,环保,军事,医疗,建筑等领域,简化了产业应用结构,为用户提供便利的同时也给企业带来了巨大的效益。物联网实质也就是将RFID技术与现实环境中网络系统、数据库等联系起来,从而组建成一个由大量联网通信的读写器设备及空间遍布标签组成比互联网更为强大全面的网络。面对当前日趋复杂的市场应用形势,对嵌入式RFID中间件的应用需求也是甚为强烈,深入研究并实现高性能的嵌入式RFID中间件,对RFID中间件技术的推广和应用具有重要的意义。嵌入式RFID中间件推广面临的一大难点在于平台的有限资源环境,在保证系统的各功能模块正常工作的基础上,合理分配优化系统资源。本文提出的嵌入式RFID中间件体系框架,根据功能结构划分为三个层次,分别为设备管理层、数据管理层、应用接口层等,并将各层功能实现以模块划分,使得各功能部分实现具有一定的独立性,便于测试,实现了设备操控、网络管理、标签数据读写、数据解析、数据过滤、数据存储等功能。通过统一监管读写器设备将各类设备对象标准化,只提供出一类标准形式接口给上层系统调用,底层设备数量及类型的变动不会影响上层应用程序访问操作,利用数据调度方法缓解了应用环境中数据处理的压力。加快整体运行速率,改善了系统工作性能。最后本文在实验室的嵌入式开发平台环境中对所设计的嵌入式RFID中间件进行了测试验证。从底层标签数据读写,读写器设备管理,数据解析和过滤等数据处理,到应用层用户访问操作,涵盖系统整体架构功能,测试结果表明该嵌入式RFID中间件各部分功能正常,性能指标达到预定设计要求。整个嵌入式RFID中间件系统设计层次结构清晰明了,具有较好的灵活性和可扩展性。
[Abstract]:Radio Frequency Identification (RFID) is a non-contact automatic identification technology with wide application prospects. As an intermediate bridge connecting the RFID reader equipment with the upper application system, it is responsible for the data and information exchange between them. In the development of Internet of things technology, the RFID industry is in the forefront, and its application has been widely used in intelligent industry, animal husbandry, etc. Agriculture, logistics, transportation, trade, environmental protection, military, medical care, construction and other fields have simplified the industrial application structure. The Internet of things, in essence, links RFID technology with network systems, databases, and so on in the real environment. In order to form a more powerful and comprehensive network composed of a large number of read and write devices with Internet communication and space all over the label. In the face of the increasingly complex market application situation, The application requirement of embedded RFID middleware is also very strong. It is of great significance for the popularization and application of RFID middleware technology to deeply research and implement high performance embedded RFID middleware. One of the major difficulties in the popularization of embedded RFID middleware is the limited resource environment of the platform. On the basis of ensuring the normal operation of the functional modules of the system, the system resources are allocated and optimized reasonably. The architecture of embedded RFID middleware is proposed in this paper. According to the function structure, it is divided into three levels, namely equipment management layer, data management layer, application interface layer and so on. The function of each layer is divided into modules, which makes each functional part have certain independence and is easy to test. It realizes the functions of device control, network management, label data reading and writing, data parsing, data filtering, data storage and so on. Only a class of standard interfaces are provided for upper system calls, and changes in the number and type of devices at the bottom do not affect the access operations of the upper application. The data scheduling method is used to relieve the pressure of data processing in the application environment, to speed up the overall running rate and to improve the performance of the system. Finally, this paper tests and verifies the embedded RFID middleware designed in the embedded development platform environment of the laboratory. It processes data from the bottom tag data reading and writing, reader device management, data parsing and filtering, etc. The user access operation to the application layer covers the whole architecture function of the system. The test results show that the function of each part of the embedded RFID middleware is normal. The design hierarchy of the whole embedded RFID middleware system is clear, flexible and extensible.
