????隨著微電子技術、計算機網絡技術和通信技術的發展，無線傳感器網絡日漸成為互聯網領域研究的熱點之一。無線傳感器網絡具有“無處不在”和節點數量龐大等特點，適用于軍事、智能家居、環境監測和預報、醫療護理、建筑物狀態監控、工業控制等領域。無線傳感器網絡節點設備是構成無線傳感器網絡的基礎，基本組成和功能包括如下幾個單元：傳感單元(由傳感器和模數轉換功能模塊組成)、處理單元(由嵌入式系統構成，包括CPU、存儲器等)、通信單元(由無線通信模塊組成)和電源單元，如圖l所示。此外，可選擇的其他功能單元包括定位系統、移動系統及電源自供電系統等。通常，此類設備具有微型、低功耗" title="低功耗">低功耗、低成本、可擴展性、高安全性等特點。
2 CC2510的功能及內部結構
2.1 功能
???
????CC2510是Chipcon公司于2005年11月推出的一款2.4 GHz射頻收發器。該器件成本低，包含UHF RF收發器和高性能低功耗8051微控制器，集成了32 KB在系統可編程Flash和外設" title="外設">外設內嵌4 KBSHAM。CC2510功能強大，擁有128位AES安全協處理器和DMA功能；系統時鐘是16MHz片內RC振蕩器或26 MHz晶體振蕩器" title="晶體振蕩器">晶體振蕩器，實時時鐘采用低功耗32.768 kHz晶體振蕩器或內部34 kHz RC振蕩器；具有高靈敏度(10 kb/s下為-100 dBm)和較高的接收靈敏度和阻塞功能，支持2-FSK,GFSK和MSK等調制方式；支持數字RSSI/LQI，工作電壓2.0 V~3.6V；具有21個通用I/O接口、兩個UART/SPI接口和可編程看門狗計時器，片內有1個16位定時器和3個8 位定時器，真正的隨機號碼發生器，支持硬件調試，有兩個數據指針。
??? CC2510采用Chipcon公司的Smart RF 04技術，以0.18μm CMOS工藝制成，只需極少外部元件就可以構成性能穩定且功耗極低的片上系統(SoC)。CC2510的選擇性和敏感性指數優越，可確保短距離通信的有效性和可靠性。除上述特點外，該器件還包含8路8~14位ADC具備4種靈活的降功耗模式，從休眠狀態到工作狀態的過渡時間非?？欤瑑惹稖囟葌鞲衅鳎浅＿m合作為無線傳感器網絡節點設備。

2.2 CC2510內部結構
??
????CC2510器件的內部結構如圖2所示。其中CC2510的處理器采用兼容8051單片機內核的結構及指令系統。該內核通過3種不同的內存訪問總線(SFR，DATA和CODE/XDATA)對內存進行訪問控制。SFR總線負責將所有的外設同內存仲裁相連接，還負責CPU與射頻寄存器之間的交互。此外，在系統中還存在有一個處于核心地位的設備——內存仲裁。內存仲裁通過SFR總線將CPU、DMA模塊、存儲器以及其他外設連接在一起。內存仲裁通過4個存儲器指針選擇接入SRAM、Flash存儲器或者SVR寄存器。系統通過中斷控制器維護4種不同優先級的18個中斷源，這些中斷源被分成6組，每組關聯一種中斷優先級。為降低功耗，系統可支持4種工作模式。表1給出了這4種工作模式的特點和狀態。

????CC2510包含有8路8~14位ADC，支持單端輸入和差分輸入兩種模式，能夠采用可選正向參考電壓。ADC中還包含了一個溫度傳感器通道，可以直接連接片內集成的溫度傳感器。ADC的輸入端口復用通用I/O端口的PO部分作為AIN0-AIN7端口。圖3給出了ADC模塊的框圖。CC2510的ADC轉換結果一般為13位，這些結果通常存放于ADC數據寄存器ADCH及ADCL中。ADC轉換結束能夠觸發自己中斷。即便是由于在ADCH與ADCL之間讀取而造成ADC無法訪問數據寄存器，并因此丟失了轉換數據，中斷仍會被觸發。

????天線接收的射頻信號經過低噪聲放大器和I/Q下變頻處理后，中頻信號只有2 MHz，此混合I/Q信號經過濾波、放大、AD變換、自動增益控制、數字解調和解擴，最終恢復出傳輸的正確數據。發射機部分基于直接上變頻。CC2510的發射部分基于RF頻率的直接合成。頻率合成器包括一個完整的片上LC壓控振蕩器和一個90°的相移器，產生接收模式時下變頻器所需的I和Q路信號。26 MHz晶體振蕩器產生的頻率作為合成器、AD時鐘和數字部分時鐘的參考頻率。系統使用SFR(特殊功能寄存器)寄存器作為接口為來自CPU的數據進行緩沖，寄存器的配置和狀態可以從寄存器映射存儲器XDATA中查詢。數字基帶信號支持通道配置，包處理和數據緩沖。片上的電壓校正器產生一個校正過的1.8 V供電電壓。
3 無線傳感器網絡節點設備設計
3.1 硬件設置
???
????針對無線傳感器網絡的特點，依據CC2510的內部結構，針對器件內部已嵌入的溫度傳感器，添加其他傳感器件，可以設計基于多傳感器的無線傳感器網絡節點設備。圖4給出了基于片內溫度傳感器和光敏器件的溫度-光強傳感器的節點設備電路圖。其中Pa為光敏電阻，C21為去耦電容。器件本振信號可由外部有源晶體提供，也可由內部電路提供。由內部電路提供時需外加晶體振蕩器和負載電容，電容的取值決定于晶體的頻率及輸入容抗等參數。該設備可采用3.0V電池供電。
?
?
????射頻輸入/輸出匹配電路主要用來匹配器件的輸入/輸出阻抗，使其輸入/輸出阻抗為50 Ω。發射部分經過前端π型匹配網絡向50 Ω垂直天線饋電，如果不希望采用上述匹配網絡，可以采用T型PCB天線直接與器件相連。
3.2 軟件設置
???
????軟件設置主要包括三個方面：主機調度函數、數據采集與處理方式、射頻數據收發處理函數。對于應用多傳感器的傳感器網絡節點設備，主機調度函數可以采用有競爭的中斷方式進行全局調度。數據采集與處理方式依據硬件自身特點實現。下面通過描述性語言給出主機調度函數的實現思想：
?
????CC2510內置一個可以在不同操作狀態(模式)之間轉換的狀態機。應用該狀態機，可以通過使用寫入指令來實現狀態之間的轉換。圖5給出了射頻控制的狀態轉換圖。這里借用MARCSTATE狀態寄存器中讀出的狀態字作為各個狀態的標識。
?
?
????在節點工作過程中，設定兩個激活狀態：接收(RX)和發送(TX)，通過CPU向RFST寄存器中寫入SRX和STX指令來實現狀態的遷移。當RX被激活時，器件將處于接收狀態，直至RX終止定時器超時或者成功地收到一個包。如果射頻控制器當前位于發送狀態，并且SRX寫入，當前的發送狀態被中止，開始向RX過渡。如果射頻控制器當前位于RX狀態，當STX或者SFSTX0N命令發布時，如果是暢通的信道就進入TX狀態。如果信道不暢通，器件仍將處于RX狀態。在任何時候，SIDLF命令總是能夠迫使射頻控制器進入空閑狀態。
???
????注意：由于使用了PQT、CS、最大同步字長和同步字評價模式，可以有效減少探測到錯誤同步字的可能性。在成功地接收到數據包以后，射頻控制器將根據系統設置進入如下狀態：
??? IDLE：空閑；
??? FSTXON：在TX頻率時，頻率合成器打開并且已經準備好。用STX激活TX；
??? TX：開始發送開端；
??? RX：開始搜尋一個新的包。
???
????類似地，當TX被激活時，器件一直處于TX狀態，直到當前的包被成功地發送出。然后狀態會根據MCSMl.TXOFF_MODE設置提示的狀態改變。有關狀態轉換條件需要根據實際應用場合人為地選擇設定，在此不再贅述。
4 配置傳感器網絡節點間的通信
???
????根據CC2510的特點，可以人為設定MAC層協議以完成節點間通信，從而構成星型或者網型(MESH)無線傳感器網絡。本文設計了一種基于載波偵聽、沖突避免機制的可變包長的MAC層協議——MAC_S，采用8 bit地址標識各個無線傳感器節點，該協議支持基于RSSI的LQI鏈路質量描述、物理層采用曼徹斯特碼編碼的2-FSK調制方式。在這里，可以利用CC2510中通過軟件設定讓信號通過一個高斯濾波器，從而產生一個GFSK調制信號。限于篇幅有關這一MAC層協議的細節將另撰文論述，這里僅簡單介紹包格式及其處理過程。圖6給出了上述MAC_S協議的包格式。
?
?
????其中，4字節引導字用于標識報文開端，同步字用于提取同步信息，包長度通常包括自身在內的后續地址和載荷報文長度，校驗域通過CRC-16算法進行校驗。在發送模式下，包處理器過程如下：發送的數據幀被送入RAM中的緩存區進行相應的幀打包操作，取發送凈荷依據轉發表填入地址并計算包長度，將一定數量的可編程的開端字節，MAC_S協議用4個開端字節，然后添加兩字節的同步字，在數字據中計算和加入CRC校驗和并發送出去。在接收模式時，包處理支持將會分解數據包：首先進行開端檢測、提取RSSI信息，然后進行同步字檢測，接著檢測地址、進行地址長度匹配并計算和檢查CRC。最后將數據凈荷提交上層進行處理，從而完成一次發送和接收交互。

5 結束語
???
????CC2510是一款高集成度的工業用射頻收發器，其MAC層和PHY層可以適用于多種協議標準，工作于2.4 GHz工業、科研和醫療頻段。通過添加簡單的外設，可構成功能強大的傳感器網絡節點設備。Chipcon公司在推出芯片的同時，還提供該器件的系列評估軟件-Smart RFStusio。通過該軟件設置可以對器件進行性能和功能測試，方便用戶進行二次開發。
