公司銷售的進(jìn)口備件從國外生產(chǎn)廠家直接進(jìn)貨，

實(shí)行扁平化的銷售模式，給客戶節(jié)約了時間和成本。

我們的目標(biāo)就是國內(nèi)用戶采購國外備件遇到困難和疑難時都能找到我們。

我們能夠及時地報出優(yōu)惠的價格和迅捷的交貨期；國內(nèi)用戶采購國外備件受到*代理壟斷價格時，

我們會給用戶提供一個比較的機(jī)會，并且為客戶提供的解決方案。由于我們的訂單集中，訂貨量大，

因此我們能提供頗具競爭力的價格并能夠迅速交貨，我們*以來致力于解決國內(nèi)用戶采購國外備件中的疑難問題，

并為廣大用戶提供電氣及工控自動化成套設(shè)備的購銷、現(xiàn)場調(diào)試等全面周到的服務(wù)。

在每個平臺都有相應(yīng)的服務(wù)質(zhì)量（QoS）的要求。在ARC平臺對功耗、存儲量、處理速度、通訊能力等都有要求。S3C2410, CS8900A等芯片可以很好的滿足這些要求。在API平臺對運(yùn)行任務(wù)的個數(shù)，任務(wù)切換時間等也有要求，嵌進(jìn)式Web服務(wù)器和嵌進(jìn)式Linux能滿足這些要求。在ASP平臺要求進(jìn)行實(shí)時的參數(shù)查看和參數(shù)設(shè)定。采用Java Applet能很好的做到這些。VLT5022PT5C

對嵌進(jìn)式控制器系統(tǒng)進(jìn)行平臺的劃分，并且對各個平臺提出相應(yīng)的服務(wù)質(zhì)量參使我們在設(shè)計的初始階段對整個設(shè)計有全局的觀念，由于各個平臺之間相對獨(dú)對以后出現(xiàn)的新的設(shè)計要求和設(shè)計修改具有很好的適應(yīng)能力。

5 基于UML-RT的嵌進(jìn)式控制器設(shè)計

在對嵌進(jìn)式控制器劃分平臺后，我們可以用UML-RT的符號體系對嵌進(jìn)式控制器系統(tǒng)進(jìn)行建模。我們把建模的過程分為兩個階段。*階段是考慮系統(tǒng)的對外接口。第二階段是考慮系統(tǒng)內(nèi)部的平臺建模。

在*階段，嵌進(jìn)式控制器的建模見圖4。根據(jù)前面用例圖的需求分析，得出系統(tǒng)需要與環(huán)境交互的端口有兩個:一個是與控制對象即智能儀表進(jìn)行通訊。一個是和用戶進(jìn)行交互。為了支持和用戶交互以及控制對象通訊，我們定義了兩個容器（capsule）u :User InteRFace和t : Transfer Data。容器p :Process Data則是用來處理數(shù)據(jù)。容器可以包含相關(guān)的軟件和硬件結(jié)構(gòu)，數(shù)據(jù)傳送可通過并口和串口進(jìn)行，這種傳送和處理器藕合的很緊，我們用UML-RT的擴(kuò)展符號表示。同樣，《SW p1》表示在處理器P1上執(zhí)行的處理與控制對象通訊的程序。我們用這種方式還可以對u :User Interface和p :Process Data進(jìn)行細(xì)化。

圖4 嵌進(jìn)式控制器的*階段表示

在*階段的基礎(chǔ)之上，我們結(jié)合前面對平臺的劃分，進(jìn)行平臺建模。系統(tǒng)的ARC平臺的建模如圖5所示。

圖5 ARC平臺下的UML-RT建模

圖5表示了ARC平臺的基本組件和它們的拓?fù)鋱D結(jié)構(gòu)，利用這個圖可以進(jìn)一步的進(jìn)行對象建模。這個模型提供了一個框架，并可以方便的增加，移動，替換，修改框架內(nèi)的元素。UML-RT的端口可以有效的表示模型元素之間的接口。

API平臺處于ARC平臺和ASP平臺之間，包括RTOS嵌進(jìn)式Web服務(wù)器，設(shè)備驅(qū)動程序等。從UML-RT角度看，API平臺是ARC容器與ASP容器之間的通訊管道。在這里ARC容器和ASP容器直接通過連接器相連。

ARC Proxy從ASP容器的端口中接收調(diào)用信息，然后把這個信息通過RTOS API送到合適的設(shè)備驅(qū)動程序，讓設(shè)備驅(qū)動程序往和ARC平臺通訊。異步或同步的通訊可以通過這個方式進(jìn)行。驅(qū)動程序和RTOS是緊密相關(guān)的。ASP平臺的建模同樣可以通過類似的方式表現(xiàn)。

綜上所述，結(jié)合UML-RT和Platform進(jìn)行嵌進(jìn)式控制器的設(shè)計，我們看到它們能夠很好的對嵌進(jìn)式軟硬件進(jìn)行抽象，提供良好的文檔資料?；赨ML-RT和Platform設(shè)計的系統(tǒng)架構(gòu)，對設(shè)計過程出現(xiàn)的新的設(shè)計要求和設(shè)計修改具有很好的適應(yīng)能力，設(shè)計者可以及早的發(fā)現(xiàn)并更正錯誤。
