【摘要】：WSN(Wireless Sensor Network)技術(shù)和RFID(Radio Frequency Identification)技術(shù)是物聯(lián)網(wǎng)中兩個(gè)重要技術(shù)。利用WSN技術(shù)可以實(shí)現(xiàn)對(duì)周圍環(huán)境的感知,利用RFID技術(shù)可以實(shí)現(xiàn)對(duì)物品的標(biāo)識(shí)。隨著物聯(lián)網(wǎng)在國民生活各個(gè)方面的推廣和使用,發(fā)現(xiàn)將兩種技術(shù)進(jìn)行整合可以充分發(fā)揮兩種技術(shù)的優(yōu)勢(shì),彌補(bǔ)兩者的不足。目前已經(jīng)有很多項(xiàng)目將兩者進(jìn)行整合使用,但這些整合技術(shù)目前還不夠成熟,不能完全解決應(yīng)用場(chǎng)景中的各種困難。一些項(xiàng)目還是針對(duì)特定的硬件和應(yīng)用場(chǎng)景開發(fā)。存在開發(fā)成本高,擴(kuò)展性差,維護(hù)難度大等問題。本文設(shè)計(jì)并實(shí)現(xiàn)了在WSN環(huán)境下的RFID中間件系統(tǒng),實(shí)現(xiàn)兩種技術(shù)在物聯(lián)網(wǎng)框架下的融合。本文以RFID中間件為研究主線,首先分析了RFID中間件系統(tǒng)的關(guān)鍵技術(shù)和研究進(jìn)展。之后研究了目前WSN技術(shù)和RFID技術(shù)的四種結(jié)合方式,由于在物聯(lián)網(wǎng)框架下的融合在所有結(jié)合方式中對(duì)硬件的依賴最小,具有良好的靈活性和可擴(kuò)展性。所以本文選擇在物聯(lián)網(wǎng)框架下實(shí)現(xiàn)兩種技術(shù)的結(jié)合。本文設(shè)計(jì)的WSN環(huán)境下RFID中間件具有如下特點(diǎn):1、基于EPCGlobal標(biāo)準(zhǔn)組織發(fā)布的ALE中間件標(biāo)準(zhǔn),并利用ALE標(biāo)準(zhǔn)中提供的擴(kuò)展點(diǎn)實(shí)現(xiàn)了WSN與RFID技術(shù)的融合。2、針對(duì)現(xiàn)有問題和實(shí)際需要,使用了多種的數(shù)據(jù)庫技術(shù)。使用MySQL關(guān)系型數(shù)據(jù)庫存儲(chǔ)中間件系統(tǒng)的基本信息;使用了兩種NoSQL數(shù)據(jù)庫:使用Redis內(nèi)存數(shù)據(jù)庫存儲(chǔ)傳感器數(shù)據(jù);使用HBase分布式數(shù)據(jù)庫存儲(chǔ)傳感器數(shù)據(jù)和RFID數(shù)據(jù)融合后的海量數(shù)據(jù),解決目前物聯(lián)網(wǎng)應(yīng)用中面臨的海量數(shù)據(jù)存儲(chǔ)問題。3、利用WebService技術(shù)實(shí)現(xiàn)中間件系統(tǒng)的跨平臺(tái)特性,即任何平臺(tái)的上層應(yīng)用都可以使用中間件系統(tǒng)提供的服務(wù)。4、本文設(shè)計(jì)中間件系統(tǒng)架構(gòu)在保證可擴(kuò)展性和通用性的情況下,可以靈活部署,適合大規(guī)模應(yīng)用。最后對(duì)本文設(shè)計(jì)的中間件系統(tǒng)進(jìn)行了詳盡的測(cè)試,包括單元測(cè)試和系統(tǒng)測(cè)試。測(cè)試結(jié)果表明WSN環(huán)境下RFID中間件各個(gè)功能模塊良好,具有良好的穩(wěn)定性和可擴(kuò)展性,滿足跨平臺(tái)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.
