【摘要】：在計算機技術(shù)、互聯(lián)網(wǎng)技術(shù)和通信網(wǎng)絡(luò)技術(shù)等第一、二次信息技術(shù)浪潮之后,以“物聯(lián)網(wǎng)”技術(shù)為代表的第三次信息技術(shù)浪潮正迎我們而來�！拔锫�(lián)網(wǎng)”基于互聯(lián)網(wǎng),通過射頻識別技術(shù)、傳感技術(shù)等技術(shù),將生活中的各種物件與互聯(lián)網(wǎng)組合成一個大的智慧網(wǎng)絡(luò)。射頻識別技術(shù)作為物聯(lián)網(wǎng)中的關(guān)鍵技術(shù)之一,已經(jīng)被應(yīng)用于我們生活的各個方面,如校園卡、公交IC卡、公路ETC收費等。簡單的來說,射頻識別技術(shù)是通過電磁或者電感耦合的技術(shù)手段,實現(xiàn)電子標(biāo)簽信息的非接觸獲取的一種自動識別技術(shù)。由于目前市場上存在的超高頻讀寫器采用有線供電,并采用有線通信方式與上位機通信,所以它不能獨立工作于戶外,這極大限制的讀寫器的應(yīng)用領(lǐng)域。為了解決此問題,本論文結(jié)合太陽能采集技術(shù),在詳細(xì)分析ISO/IEC 18000-6C協(xié)議和無線通信原理的基礎(chǔ)上,設(shè)計出一款太陽能供電的超高頻無線讀寫器,研究的主要內(nèi)容有:第一,采用太陽能供電。該讀寫器的應(yīng)用場合為戶外,將太陽能電池板采集的能量存儲到大容量鋰電池中,由鋰電池給系統(tǒng)供電,并設(shè)計出電源管理電路。第二,采用藍(lán)牙模塊實現(xiàn)無線通信。該藍(lán)牙模塊功耗低、通信距離遠(yuǎn),作為讀寫器和上位機無線通信的方式。第三,超高頻讀寫器硬件電路設(shè)計。該電路采用Cortex-M3系列低功耗芯片STM32F103VET6作為主控芯片,處理基帶信號。根據(jù)UHF協(xié)議的要求設(shè)計讀寫器的發(fā)射機和接收機電路。第四,詳細(xì)分析UHF RFID協(xié)議ISO/IEC 18000-6C,并用軟件實現(xiàn)基帶信號的處理。并提出一種新的CRC校驗算法,提高讀寫器的工作效率。第五,移植嵌入式實時操作系統(tǒng)?COS-II至STM32F103VET6,實現(xiàn)多任務(wù)處理。用VS2008實現(xiàn)上位機軟件的編寫。設(shè)計完成后,對該讀寫器進(jìn)行功能測試,并給出了讀寫器的測試數(shù)據(jù),并通過該數(shù)據(jù)的出結(jié)論,讀寫器工作良好,已經(jīng)達(dá)到設(shè)計目標(biāo)。
[Abstract]:After the first and second wave of information technology, such as computer technology, Internet technology and communication network technology. The third wave of information technology, represented by "Internet of things", is welcoming us. "Internet of things" is based on the Internet of things, through radio frequency identification technology, sensing technology and other technologies. As one of the key technologies in the Internet of things, RFID technology has been applied to all aspects of our life, such as campus cards. Bus IC card, highway ETC toll, etc. Simply put, radio frequency identification technology is through electromagnetic or inductive coupling technology. An automatic recognition technology for non-contact acquisition of tag information. Because of the existence of UHF reader-writer in the market at present, the UHF reader uses wired power supply and uses wired communication to communicate with the host computer. Therefore, it can not work independently outside, which greatly limits the application of the reader. In order to solve this problem, this paper combines solar energy acquisition technology. Based on the detailed analysis of ISO/IEC 18000-6C protocol and the principle of wireless communication, a solar-powered UHF wireless reader is designed. The main contents of the research are as follows: first. Solar power supply is used. The application of the reader is outdoor. The energy collected by solar panel is stored in the large capacity lithium battery. The system is powered by lithium battery and the power management circuit is designed. Bluetooth module is used to realize wireless communication. The Bluetooth module has low power consumption and long communication distance, which is used as a way of wireless communication between reader and host computer. Third. The hardware circuit of UHF reader is designed, which uses Cortex-M3 series low power chip STM32F103VET6 as the main control chip. Design transmitter and receiver circuit of reader according to the requirement of UHF protocol. 4th, analyze ISO/IEC 18000-6C of UHF RFID protocol in detail. A new CRC verification algorithm is proposed to improve the efficiency of the reader. 5th, transplant embedded real-time operating system? COS-II to STM32F103VET6 to achieve multi-task processing. Using VS2008 to realize the PC software programming. After the design is completed, the reader is tested. The test data of the reader are given, and the conclusion of the data shows that the reader works well and has reached the design goal.
