摘要:現(xiàn)代通信中，無線技術(shù)已經(jīng)進(jìn)入到我們的生活的方方面面。在各種工業(yè)應(yīng)用環(huán)境中、對有線通訊無法到達(dá)的區(qū)域、或人類無法到達(dá)的惡劣的環(huán)境中，無線節(jié)點(diǎn)能夠更好的發(fā)揮它的作用。無線微節(jié)點(diǎn)是近年來無線傳感器網(wǎng)絡(luò)應(yīng)用的主要形式。無線微節(jié)點(diǎn)所具有的超低功耗、體積小、能在各種惡劣的環(huán)境下工作的特點(diǎn)，使無線微節(jié)點(diǎn)得到越來越廣泛的應(yīng)用。 本論文針對交通檢測領(lǐng)域的無線應(yīng)用問題，基于TI公司無線微節(jié)點(diǎn)芯片CC1101研究設(shè)計(jì)和實(shí)現(xiàn)了一種具有超低能耗的、實(shí)時(shí)穩(wěn)定的微節(jié)點(diǎn)無線通信協(xié)議。論文簡要介紹了協(xié)議中數(shù)據(jù)包格式的確定、傳輸錯(cuò)誤的檢測與處理、數(shù)據(jù)收發(fā)端的同步等問題；詳細(xì)分析了使用CC1101進(jìn)行無線通信時(shí)的節(jié)能設(shè)計(jì)和防沖突設(shè)計(jì)原理，對通信實(shí)現(xiàn)時(shí)的數(shù)據(jù)包處理、收發(fā)協(xié)議的實(shí)現(xiàn)等做了闡述，同時(shí)也說明了使用89C52單片機(jī)進(jìn)行無線通信的軟硬件設(shè)計(jì)方法；最后用一個(gè)實(shí)例展示了無線通信協(xié)議的應(yīng)用。 關(guān)鍵詞: CC1101；無線通信；協(xié)議
Abstract:In modern communication, wireless technology has been applied into all aspects of our lives. Wireless nodes can play better role in the application of various industries unable to arrive at, the area that the wired communication can not reach, or the poor environment. Wireless micro node is the main form of the application of wireless sensor networks in recent years. Wireless micro node has the Characteristics of ultra low power consumption, small volume, working in a variety of harsh environment ,whitch make it possible that the application of the wireless micro node will get more and more extensive. In this paper, it designs and realizes a wireless communication protocol that has the character of real-time stability with low energy consumption whitch based on CC1101 chip made by TI comply for the wireless application problems on traffic detection field. This paper briefly introduces the problem of forming the protocol packet format, the determination of transmission error detection and data processing, such as synchronization of transmitter and receiver .It discribes detaily the analysis of the principle of energy-saving and the anti-collision in the use of CC1101. It also describes the processing of communication between the data packetand implementation of sending and receiving protocol, and the hardware and software design method using 89C52 microcontroller wireless communication. Finally ,it shows the application of wireless communication protocol through an example. Keywords: CC1101 Wireless communication Protocol
近年來由于微電子技術(shù)、計(jì)算機(jī)技術(shù)和無線通信技術(shù)的進(jìn)步，使得大量低功耗、多功能、低成本、對等通信的無線節(jié)點(diǎn)的問世成為可能。有多個(gè)節(jié)點(diǎn)共同構(gòu)成的網(wǎng)絡(luò)吸引了大量學(xué)者的興趣。在環(huán)境監(jiān)測、交通運(yùn)輸、醫(yī)療等領(lǐng)域的科學(xué)研究中得到廣泛的應(yīng)用。 無線節(jié)點(diǎn)通信的節(jié)點(diǎn)通常配備一個(gè)或多個(gè)不同的傳感器，用于完成采集物理數(shù)據(jù)的任務(wù)。同時(shí)在節(jié)點(diǎn)上還配置了存儲器、微處理器、執(zhí)行器、電源和射頻收發(fā)器等。與傳統(tǒng)的無線節(jié)點(diǎn)不同，現(xiàn)在的無線節(jié)點(diǎn)體積小、價(jià)格便宜，但是節(jié)點(diǎn)的能量相對較弱。除此之外，現(xiàn)代無線節(jié)點(diǎn)常用電池來供電，并且常常工作在惡劣的環(huán)境或是工作在敵方區(qū)域，不能提供電池補(bǔ)給或更換，因而電源也是約束無線節(jié)點(diǎn)的一個(gè)重要因素。 無線節(jié)點(diǎn)通信的研究目標(biāo)是滿足上述約束條件的同時(shí)完成指定的任務(wù)。引入新的設(shè)計(jì)概念、開發(fā)或改進(jìn)現(xiàn)有協(xié)議、開創(chuàng)新的應(yīng)用領(lǐng)域、開發(fā)新的算法，都將成為無線節(jié)點(diǎn)通信的熱點(diǎn)。
