【摘要】：WSN(Wireless Sensor Network)技术和RFID(Radio Frequency Identification)技术是物联网中两个重要技术。利用WSN技术可以实现对周围环境的感知,利用RFID技术可以实现对物品的标识。随着物联网在国民生活各个方面的推广和使用,发现将两种技术进行整合可以充分发挥两种技术的优势,弥补两者的不足。目前已经有很多项目将两者进行整合使用,但这些整合技术目前还不够成熟,不能完全解决应用场景中的各种困难。一些项目还是针对特定的硬件和应用场景开发。存在开发成本高,扩展性差,维护难度大等问题。本文设计并实现了在WSN环境下的RFID中间件系统,实现两种技术在物联网框架下的融合。本文以RFID中间件为研究主线,首先分析了RFID中间件系统的关键技术和研究进展。之后研究了目前WSN技术和RFID技术的四种结合方式,由于在物联网框架下的融合在所有结合方式中对硬件的依赖最小,具有良好的灵活性和可扩展性。所以本文选择在物联网框架下实现两种技术的结合。本文设计的WSN环境下RFID中间件具有如下特点:1、基于EPCGlobal标准组织发布的ALE中间件标准,并利用ALE标准中提供的扩展点实现了WSN与RFID技术的融合。2、针对现有问题和实际需要,使用了多种的数据库技术。使用MySQL关系型数据库存储中间件系统的基本信息;使用了两种NoSQL数据库:使用Redis内存数据库存储传感器数据;使用HBase分布式数据库存储传感器数据和RFID数据融合后的海量数据,解决目前物联网应用中面临的海量数据存储问题。3、利用WebService技术实现中间件系统的跨平台特性,即任何平台的上层应用都可以使用中间件系统提供的服务。4、本文设计中间件系统架构在保证可扩展性和通用性的情况下,可以灵活部署,适合大规模应用。最后对本文设计的中间件系统进行了详尽的测试,包括单元测试和系统测试。测试结果表明WSN环境下RFID中间件各个功能模块良好,具有良好的稳定性和可扩展性,满足跨平台使用的需求。
[Abstract]:WSN(Wireless Sensor Network and RFID(Radio Frequency Identification are two important technologies in the Internet of things.Using WSN technology can realize the perception of the surrounding environment, and using RFID technology can realize the identification of objects.With the popularization and use of the Internet of things in all aspects of national life, it is found that the integration of the two technologies can give full play to the advantages of the two technologies, and make up for the shortcomings of the two technologies.At present, there are many projects to integrate the two technologies, but these integration technologies are not mature enough to completely solve the difficulties in the application scenarios.Some projects are developed for specific hardware and application scenarios.There are problems such as high development cost, poor expansibility and difficult maintenance.In this paper, we design and implement the RFID middleware system based on WSN, and realize the integration of the two technologies under the framework of the Internet of things.Taking RFID middleware as the main research thread, this paper firstly analyzes the key technology and research progress of RFID middleware system.After that, four kinds of combination methods of WSN technology and RFID technology are studied. Because the integration in the Internet of things framework has the least dependence on hardware, it has good flexibility and expansibility.So this paper chooses to realize the combination of two technologies under the framework of Internet of things.The RFID middleware in the WSN environment designed in this paper has the following characteristics: 1, based on the ALE middleware standard issued by the EPCGlobal standard organization, and using the extension point provided in the ALE standard to realize the integration of WSN and RFID technology, aiming at the existing problems and actual needs.A variety of database techniques are used.MySQL relational database is used to store basic information of middleware system, two kinds of NoSQL database are used: Redis memory database is used to store sensor data, HBase distributed database is used to store sensor data and mass data after RFID data fusion.To solve the problem of mass data storage in the Internet of things application. 3, using WebService technology to realize the cross-platform characteristics of middleware system,The upper application of any platform can use the service provided by the middleware system. This paper designs the middleware system architecture which can be flexibly deployed and suitable for large-scale application under the condition of scalability and universality.Finally, the middleware system designed in this paper is tested in detail, including unit test and system test.The test results show that each function module of RFID middleware in WSN environment is good, has good stability and scalability, and meets the requirements of cross-platform use.
