【摘要】:射頻識別(Radio Frequency Identification, RFID),是一種具有廣泛的應(yīng)用前景非接觸的自動識別技術(shù)。在RFID應(yīng)用系統(tǒng)中,RFID中間件是其中重要的組成部分,其作為將RFID讀寫器設(shè)備與上層應(yīng)用系統(tǒng)連接起來的中間橋梁,負(fù)責(zé)它們之間的數(shù)據(jù)信息交互。物聯(lián)網(wǎng)技術(shù)發(fā)展中RFID產(chǎn)業(yè)規(guī)模位居前列,其應(yīng)用已遍及智能化工業(yè),畜牧業(yè),農(nóng)業(yè),物流,交通,貿(mào)易,環(huán)保,軍事,醫(yī)療,建筑等領(lǐng)域,簡化了產(chǎn)業(yè)應(yīng)用結(jié)構(gòu),為用戶提供便利的同時也給企業(yè)帶來了巨大的效益。物聯(lián)網(wǎng)實質(zhì)也就是將RFID技術(shù)與現(xiàn)實環(huán)境中網(wǎng)絡(luò)系統(tǒng)、數(shù)據(jù)庫等聯(lián)系起來,從而組建成一個由大量聯(lián)網(wǎng)通信的讀寫器設(shè)備及空間遍布標(biāo)簽組成比互聯(lián)網(wǎng)更為強(qiáng)大全面的網(wǎng)絡(luò)。面對當(dāng)前日趨復(fù)雜的市場應(yīng)用形勢,對嵌入式RFID中間件的應(yīng)用需求也是甚為強(qiáng)烈,深入研究并實現(xiàn)高性能的嵌入式RFID中間件,對RFID中間件技術(shù)的推廣和應(yīng)用具有重要的意義。 嵌入式RFID中間件推廣面臨的一大難點在于平臺的有限資源環(huán)境,在保證系統(tǒng)的各功能模塊正常工作的基礎(chǔ)上,合理分配優(yōu)化系統(tǒng)資源。本文提出的嵌入式RFID中間件體系框架,根據(jù)功能結(jié)構(gòu)劃分為三個層次,分別為設(shè)備管理層、數(shù)據(jù)管理層、應(yīng)用接口層等,并將各層功能實現(xiàn)以模塊劃分,使得各功能部分實現(xiàn)具有一定的獨立性,便于測試,實現(xiàn)了設(shè)備操控、網(wǎng)絡(luò)管理、標(biāo)簽數(shù)據(jù)讀寫、數(shù)據(jù)解析、數(shù)據(jù)過濾、數(shù)據(jù)存儲等功能。通過統(tǒng)一監(jiān)管讀寫器設(shè)備將各類設(shè)備對象標(biāo)準(zhǔn)化,只提供出一類標(biāo)準(zhǔn)形式接口給上層系統(tǒng)調(diào)用,底層設(shè)備數(shù)量及類型的變動不會影響上層應(yīng)用程序訪問操作,利用數(shù)據(jù)調(diào)度方法緩解了應(yīng)用環(huán)境中數(shù)據(jù)處理的壓力。加快整體運行速率,改善了系統(tǒng)工作性能。 最后本文在實驗室的嵌入式開發(fā)平臺環(huán)境中對所設(shè)計的嵌入式RFID中間件進(jìn)行了測試驗證。從底層標(biāo)簽數(shù)據(jù)讀寫,讀寫器設(shè)備管理,數(shù)據(jù)解析和過濾等數(shù)據(jù)處理,到應(yīng)用層用戶訪問操作,涵蓋系統(tǒng)整體架構(gòu)功能,測試結(jié)果表明該嵌入式RFID中間件各部分功能正常,性能指標(biāo)達(dá)到預(yù)定設(shè)計要求。整個嵌入式RFID中間件系統(tǒng)設(shè)計層次結(jié)構(gòu)清晰明了,具有較好的靈活性和可擴(kuò)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.
