無線傳感器網(wǎng)絡(luò)是以遙感檢測目標(biāo)信息為主的一種新型無線網(wǎng)絡(luò)，主要由無線傳感器節(jié)點(diǎn)組成,。典型的無線傳感器系統(tǒng)如圖1,，主要由部署在遙感檢測區(qū)域內(nèi)的成千上萬個(gè)傳感器終端節(jié)點(diǎn),、匯聚節(jié)點(diǎn)（網(wǎng)關(guān)或基站）和監(jiān)控/管理中心及其他外部網(wǎng)絡(luò)組成。其中,，傳感器終端節(jié)點(diǎn)具有數(shù)據(jù)采集,、傳輸和轉(zhuǎn)發(fā)鄰節(jié)點(diǎn)數(shù)據(jù)的多重功能，它與匯聚節(jié)點(diǎn)能夠自動(dòng)形成一個(gè)自組織,、多跳的網(wǎng)絡(luò),，傳感器終端節(jié)點(diǎn)周期性或者觸發(fā)式地采集數(shù)據(jù)，并將數(shù)據(jù)經(jīng)過多跳路由傳輸?shù)絽R聚節(jié)點(diǎn),。匯聚節(jié)點(diǎn)是網(wǎng)絡(luò)的中心,，具有協(xié)調(diào)器和網(wǎng)關(guān)的作用，負(fù)責(zé)網(wǎng)絡(luò)的配置,、管理和數(shù)據(jù)的匯聚,，并負(fù)責(zé)與用戶PC機(jī)后臺(tái)監(jiān)控系統(tǒng)的通信。匯聚節(jié)點(diǎn)將匯集的數(shù)據(jù)轉(zhuǎn)發(fā)給后臺(tái)監(jiān)控系統(tǒng),，后臺(tái)監(jiān)控系統(tǒng)通過對(duì)數(shù)據(jù)的處理與判斷,，對(duì)傳感器終端節(jié)點(diǎn)進(jìn)行控制[1]。

3 無線傳感器網(wǎng)絡(luò)節(jié)點(diǎn)硬件設(shè)計(jì)
3.1 無線傳感器網(wǎng)絡(luò)節(jié)點(diǎn)
在本設(shè)計(jì)中,，考慮到系統(tǒng)的擴(kuò)展性和靈活性,，無線傳感器節(jié)點(diǎn)要定義統(tǒng)一、標(biāo)準(zhǔn)的接口,，在需要添加新的硬件部件時(shí)可以在現(xiàn)有節(jié)點(diǎn)上直接添加,，同時(shí)節(jié)點(diǎn)可以按照功能拆分成多個(gè)模塊，模塊之間可以通過標(biāo)準(zhǔn)接口自由組合,。在不同的應(yīng)用環(huán)境下選擇不同的模塊自由配置系統(tǒng),，這樣就不必為每個(gè)應(yīng)用都開發(fā)一套全新的硬件系統(tǒng)?；谝陨峡紤],，選擇了TI最新推出的高集成度的無線SoC CC1111。CC1111芯片在應(yīng)用方面易于擴(kuò)展,，只需要少許外圍元件就可以與傳感器相接,，也可以通過全速USB2.0的接口與計(jì)算機(jī)連接。圖2為基于CC1111的無線傳感器網(wǎng)絡(luò)的節(jié)點(diǎn)設(shè)計(jì)框架,。
?
傳感器終端節(jié)點(diǎn)主要由數(shù)據(jù)采集模塊(由傳感器和ADC模塊組成),、主控制模塊(包括微處理器、存儲(chǔ)器,、嵌入式操作系統(tǒng),、射頻通信模塊等)和電源模塊組成,。匯集節(jié)點(diǎn)實(shí)現(xiàn)兩個(gè)通信網(wǎng)絡(luò)之間數(shù)據(jù)的交換,，實(shí)現(xiàn)兩種協(xié)議棧之間的通信協(xié)議轉(zhuǎn)換,，它發(fā)布管理節(jié)點(diǎn)的監(jiān)測任務(wù)，并把收集到的數(shù)據(jù)轉(zhuǎn)發(fā)到外部網(wǎng)絡(luò)上,。它既可以是一個(gè)增強(qiáng)功能的傳感器節(jié)點(diǎn),，也可以是沒有監(jiān)測功能僅帶無線通信接口的特殊網(wǎng)關(guān)設(shè)備，主要包括數(shù)據(jù)采集模塊,、主控制模塊,、網(wǎng)關(guān)接口模塊和電源模塊。模塊之間相對(duì)獨(dú)立,，預(yù)留接口,，便于以后系統(tǒng)的升級(jí)和維護(hù)，同時(shí)也降低了系統(tǒng)成本,。實(shí)際部署在監(jiān)測區(qū)域內(nèi)的傳感器節(jié)點(diǎn)由數(shù)據(jù)采集模塊,、主控制模塊和電源構(gòu)成，只有傳感器節(jié)點(diǎn)充當(dāng)網(wǎng)關(guān)節(jié)點(diǎn)和系統(tǒng)維護(hù)時(shí)才接插網(wǎng)關(guān)接口模塊,。節(jié)點(diǎn)一般采用電池供電,，一旦電源耗盡，節(jié)點(diǎn)就失效了,。為了最大限度地節(jié)約電源,，在硬件設(shè)計(jì)方面，盡量選用低功耗,、高集成度的器件,，在節(jié)點(diǎn)空閑時(shí)切斷射頻模塊電源；在軟件設(shè)計(jì)方面,，各層通信協(xié)議都應(yīng)該以提高能量利用率為主,，獲得更高的電源效率。
3.2 數(shù)據(jù)采集模塊
節(jié)點(diǎn)的數(shù)據(jù)采集部分可根據(jù)實(shí)際需要選定參數(shù),、性能合適的傳感器,，例如溫度、濕度,、壓力,、加速度等。一般無線傳感器網(wǎng)絡(luò)系統(tǒng)要求傳感器體積小,、功耗低,、外圍電路簡單，最好采用不需要信號(hào)調(diào)理電路的數(shù)字式傳感器,。傳感器作為獲取外部狀態(tài)信號(hào)的一部分,，傳感器模塊通常由傳感器探頭和變送系統(tǒng)兩部分組成，都必須通過傳感器接口連接主控制模塊,。CC1111提供了19個(gè)I/O口,，便于擴(kuò)展,，連接不同類型的傳感器，它們可以對(duì)傳感器獲得的模擬信號(hào)進(jìn)行A/D轉(zhuǎn)換或?yàn)V波處理,，以達(dá)到數(shù)據(jù)處理和控制模塊所能接受的信號(hào)形式,。傳感器的工作原理如下：首先將測得的物理量通過一定的轉(zhuǎn)換機(jī)制轉(zhuǎn)換成電信號(hào)，然后將獲得的電信號(hào)通過積分電路,、放大電路進(jìn)行整形濾波處理,，最后通過采集電路將處理過的模擬信號(hào)轉(zhuǎn)換成數(shù)字信號(hào)。因此,，CC1111芯片適應(yīng)于各類數(shù)據(jù)采集情況,。
3.3 主控制模塊
本設(shè)計(jì)采用的主控制模塊為TI的SoC CC1111，它結(jié)合了多種器件的優(yōu)異性能,，其中包括TI最佳的RF收發(fā)器(CC1101),、增強(qiáng)型8051微控制器(每MHz性能可達(dá)標(biāo)準(zhǔn)8051性能的8倍)、8/16/32KB的可編程閃存,、1/2/4KB的RAM以及全速USB2.0控制器,，能夠顯著提高低功耗無線傳感器網(wǎng)絡(luò)的性能。RF收發(fā)器集成了一個(gè)高度可配置的調(diào)制解調(diào)器,，支持不同的調(diào)制格式,，其數(shù)據(jù)傳輸率可達(dá)500kb/s。通過開啟集成在調(diào)制解調(diào)器上的前向誤差校正選項(xiàng),，能使性能得到提升,。CC1111為數(shù)據(jù)包處理、數(shù)據(jù)緩沖,、突發(fā)數(shù)據(jù)傳輸,、清晰信道評(píng)估、連接質(zhì)量指示和電磁波激發(fā)提供廣泛的硬件支持,。所以,，CC1111芯片使原有的微處理器模塊和無線通信兩大模塊的設(shè)計(jì)只需要一塊芯片就可以完成，減小了整個(gè)系統(tǒng)的體積,，降低了成本和功耗,。而且無線收發(fā)電路和8051單片機(jī)系統(tǒng)有機(jī)地整合在同一晶片上，最大限度地減少了單片機(jī)數(shù)字電路對(duì)高頻模擬電路的干擾,，提高了可靠性,。
CC1111芯片集成了完整的無線收發(fā)電路。在接收模式下,，相當(dāng)于一個(gè)傳統(tǒng)的超外差接收器,，射頻(RF)輸入信號(hào)經(jīng)低噪聲放大器(LNA)放大后翻轉(zhuǎn)進(jìn)入混頻器，通過混頻器混頻產(chǎn)生中頻(IF)信號(hào)。在IF處理階段,該信號(hào)在送入解調(diào)器前被放大和濾波,?？蛇x的RSSI信號(hào)或IF信號(hào)也可通過混頻產(chǎn)生于引腳RSSI/IF。解調(diào)后從引腳DIO輸出解調(diào)數(shù)字信號(hào),，解調(diào)信號(hào)的同步由芯片提供的時(shí)鐘信號(hào)完成。在發(fā)送模式下,，芯片內(nèi)部VCO(壓控振蕩器)的輸出信號(hào)直接送入功率放大器,，RF輸出是由微控制器的數(shù)字比特流頻移鍵控形成的。頻率合成器產(chǎn)生的本振信號(hào)在接收模式時(shí)送到混頻器,，然后在發(fā)射模式時(shí)饋送到功率放大器[2],。
3.4 電源模塊
電能決定整個(gè)網(wǎng)絡(luò)的壽命，節(jié)點(diǎn)的電能一旦耗盡,，其壽命到期并退出網(wǎng)絡(luò),，由其余節(jié)點(diǎn)重新組網(wǎng)。所以節(jié)點(diǎn)的電源管理非常重要,。CC1111芯片有四種工作模式：PM0,、PM1、PM2和PM3,。通過軟件編程或硬件復(fù)位可以在四種模式下任意轉(zhuǎn)換,，有很強(qiáng)的操作性，并具有電源消耗低的特點(diǎn),。此芯片系統(tǒng)同時(shí)還支持節(jié)電模式下的外部中斷觸發(fā)（可支持所有引腳）喚醒及實(shí)時(shí)計(jì)數(shù)器事件觸發(fā)喚醒,。為了延長系統(tǒng)中電池的供電時(shí)間，無線傳感器節(jié)點(diǎn)通常在閑置時(shí)快速進(jìn)入休眠模式,，其外設(shè)模塊（各個(gè)傳感器功能模塊）進(jìn)入休眠狀態(tài),，或者電源管理部分不對(duì)這些外設(shè)模塊供電，因此電源管理部分應(yīng)具有對(duì)各個(gè)模塊是否供電的控制能力,，并由CPU 進(jìn)行控制[3],。另外，由于CC1111芯片同時(shí)集成了收發(fā)功能和處理功能,，提高了電源供電效率,。因此，只需使用兩節(jié)5號(hào)鋰電池,，根據(jù)節(jié)點(diǎn)工作頻率的不同,，電池可以工作1～5年而不需要更換。
3.5 PCB和天線的設(shè)計(jì)
射頻收發(fā)產(chǎn)品的PCB布局對(duì)整個(gè)系統(tǒng)的性能影響很大,，為了使用戶得到最好的收發(fā)性能,，TI給用戶提供了參考PCB。CC1111的PCB至少為4層板,，分別為頂層,、中間地層,、中間正電源層和底層。為了消除走線間的感性效應(yīng),，應(yīng)在PCB上空余的地方盡量多地布置一些過孔,，濾波電容也應(yīng)該盡量靠相應(yīng)的引腳布置，這樣可以得到更好的濾波性能,。芯片的接地引腳,，距離使用單獨(dú)過孔的封裝引腳越近越好。外圍元器件應(yīng)盡量小,，盡量使用體積小的貼片器件,。CC1111可使用單極天線、環(huán)形天線或螺旋天線,。單極天線的長度為波長的1/4,，其長度根據(jù)L=7125/f計(jì)算，其中f的單位是MHz,，L的單位是cm,；環(huán)形天線布在PCB上，使用非常方便,，但由于其輻射能力較差,，所以接收/發(fā)射性能也稍差些；螺旋天線是單極天線和環(huán)形天線的一種折衷方案,，其尺寸大小和接收/發(fā)射能力介于兩者之間,。
4 無線傳感器網(wǎng)絡(luò)節(jié)點(diǎn)軟件設(shè)計(jì)
無線傳感器網(wǎng)絡(luò)系統(tǒng)的數(shù)據(jù)傳輸主要由無線傳感器終端節(jié)點(diǎn)、匯聚節(jié)點(diǎn)和PC機(jī)組成,，PC機(jī)與匯聚節(jié)點(diǎn)間通過全速USB2.0接口通信,，整個(gè)系統(tǒng)的各個(gè)部分都是為無線數(shù)據(jù)傳輸服務(wù)的。所以,，在整個(gè)系統(tǒng)的軟件設(shè)計(jì)中,，無線數(shù)據(jù)傳輸是最主要的部分。圖3和圖4為無線數(shù)據(jù)傳輸?shù)陌l(fā)送和接收軟件流程,。

無線傳感器網(wǎng)絡(luò)技術(shù)具有成本低,、無需通訊電纜、不受應(yīng)用環(huán)境限制,、組網(wǎng)靈活,、重構(gòu)性強(qiáng)等優(yōu)點(diǎn)，這就給無線傳感器網(wǎng)絡(luò)技術(shù)帶來了很大的發(fā)展空間,?；贑C1111芯片構(gòu)成的無線傳感器網(wǎng)絡(luò)節(jié)點(diǎn)系統(tǒng)可以在多種環(huán)境中工作，按各種需要進(jìn)行配置完成系統(tǒng)功能，并且在成本,、空間,、功耗、靈活性等方面具有明顯的優(yōu)勢,，選擇的硬件模塊顯著延長了節(jié)點(diǎn)的工作壽命,，增加了節(jié)點(diǎn)的通信范圍，提高了節(jié)點(diǎn)的通信速率,；同時(shí),，由于沒有額外增加微處理器的開銷和總體功耗，為開發(fā)和構(gòu)造無線傳感器網(wǎng)絡(luò)開拓了新的應(yīng)用前景,。隨著MEMS等集成技術(shù)的進(jìn)一步發(fā)展和節(jié)點(diǎn)的大規(guī)模生產(chǎn)，單個(gè)節(jié)點(diǎn)的成本會(huì)很快下降,?？梢灶A(yù)見，CC1111將會(huì)得到越來越廣泛的應(yīng)用,。
